        tests: drop unnecessary requirement in 'subpkg.test'
        * tests/subpkg.test ($required): Drop "bison", it is not required
        anymore since commit `v1.11-502-g7e5ae80'.

        gitlog-to-changelog: new auxiliary script, synced from gnulib

        We have plans to stop maintaining a version-controlled ChangeLog
        file in the Automake repository, and instead begin to generate it
        automatically from the git log messages.  To do so, we will use
        the `gitlog-to-changelog' script from gnulib.

        * lib/gitlog-to-changelog: New, synced from gnulib.
        * Makefile.am (fetch): Fetch and sync it.
        * lib/Makefile.am (EXTRA_DIST): Distribute it.

        regex: remove obsolete macro AM_WITH_REGEX
        Today, practically nobody uses the GNU rx library, which, according
        to its own website <http://www.gnu.org/software/rx/rx.html>, has
        been "decommissioned".  Consequently, the automake-provided macro
        AM_WITH_REGEX is not used nor required anymore.
        * m4/regex.m4: Delete.
        * m4/Makefile.am (dist_automake_ac_DATA): Do not list it anymore.
        * doc/automake.texi (Obsolete Macros): Remove description, and in
        fact any mention, of `AM_WITH_REGEX'.
        * tests/regex.test: Delete.
        * tests/help-regex.test: Likewise.
        * tests/regex-obsolete.test: Likewise.

        See also commits `v1.11-587-g5f335be' and `v1.11-433-g37b0aee',
        where that macro had been deprecated.

        tap/awk: "Bail out!" recognized also after leading whitespace
        Newer versions of TAP::Harness (e.g., 3.23 on Perl 5.14.1)
        recognize a "Bail out!" directive also when it is prepended by
        leading whitespace; this was not the case for older TAP:Harness
        versions, (e.g., for version 3.17 on Perl 5.12.4), and for our
        TAP driver implemented in awk.
        * lib/tap-driver.sh: Handle the "Bail out!" directive also when
        it is preceded by leading whitespace.
        * tests/tap-spurious.test: Remove the tests checking that a
        "Bail out!" string coming right after leading whitespace does
        not trigger a bailout action.
        * tests/tap-bailout-leading-space.test: New test.
        * tests/list-of-tests.mk: Add it.

        tests: fix spurious failure of cond29.test
        * tests/cond29.test: Limit the amount of virtual memory available
        to the automake process to ~ 150 MB, rather than only ~ 20 MB, to
        account for higher (but still acceptable) memory usages on some
        systems (in this case, a Fedora 16 distro on ppc64).  To be
        sure not to reduce coverage, increase the number of potential
        combinations of automake conditionals from 2**22 = 4194304 to
        2**24 = 16777216.
        We have actually verified that the new version of the test case
        catches the Automake 1.7 it is intended to check against, using
        the Automake 1.7.9 tarball downloaded from:
          <http://ftp.gnu.org/gnu/automake/automake-1.7.9.tar.gz>
        Reported by Jim Meyering in automake bug#10374.

        docs: "aclocal --install -I /abs/dir" actually copies files

        This change is for automake bug#8407.

        In the past, there had been some debate and confusion about
        whether "aclocal --install" should copy third-party .m4 files
        in the first directory passed to the `-I' option even when
        such directory was given as an absolute path, or whether it
        was better to do so only for directories specified with a
        relative path.

        The rationale for this latter behaviour was that, before the
        existence of the `ACLOCAL_PATH' variable, the only way (a poor
        way, I might add) for a common user to extend the search path
        of a system-wide installation of aclocal was to export something
        like ACLOCAL="aclocal -I /my/extra/macros" in the environment.
        Today, the correct way to proceed is undoubtedly through the
        use of ACLOCAL_PATH, so we can settle the question once and for
        all, and start verifying the correct behaviour of `-I' with a
        new test.

        * tests/aclocal-install-absdir.test: New test.
        * tests/Makefile.am (TESTS): Add it.
        * doc/automake.texi (aclocal Options): Be more explicit about
        this part of `--install' semantics.

        docs: fix node names for automake and aclocal invocations

        With the older node names, an "info automake" command issued
        from the command line would have opened the node about the
        invocation of the automake program, rather than the Top node
        of the automake documentation.  To invoke the Top node, one
        had to issue the command "info Automake" instead (note the
        different capitalization).  This was suboptimal, and certainly
        confusing.

        With this change, "info automake" will open the Top node of the
        automake documentation; to access the nodes about the invocation
        of the automake and aclocal program, one has now to issue "info
        automake-invocation" and "info aclocal-invocation" respectively.

        This change fixes automake bug#8071.

        See also commits `v2.61a-22-ge9215d1' and `v2.61a-72-g8c07b48' in
        the autoconf git repository, which tackled a similar issue.

        * doc/automake.texi (@direntry): Rename nodes `aclocal' and
        `automake' to `aclocal-invocation' and `automake-invocation'
        respectively.
        * NEWS: Update.

2011-12-26  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tests: tweak tests on silent-rules for makes without nested vars
        * tests/silent-nested-vars.test: Define $MAKE to `./mymake' in
        the environment, so that it will be automatically picked up by
        configure.  Related tweaks and simplifications.
        Remove the checks verifying that silent rules are respected also
        when the 'subdir-objects' option is set, the checks testing the
        old syntax for user-defined silent rules, and the tests using
        the default $MAKE programs: they are redundant w.r.t. other test
        cases.  Related simplifications.
        Remove the temporary files used in a sanity check as soon as they
        are not needed anymore.
        Do not capture also the standard error of configure: we only want
        to grep its standard output.
        Consistently use `stdout' for the name of files where to save the
        standard output captured from make and configure, for consistency
        with other tests.
        Make grepping of configure output and of the generated Makefile
        stricter.
        Improve and tweak the `mymake' script a little.
        * tests/silent6.test: Make grepping of make stdout slightly
        stricter.  After having configured with silent rules disabled,
        try to force the use silent rules with `make V=1'.

        silent-rules: fallback for makes without nested vars

        This fixes two problems reported for Automake (Bug#9928, Bug#10237)
        and is in response to a bug report for building coreutils on HP
        NonStop OS (Bug#10234).  The problem is that HP NonStop 'make'
        treats a line like "AM_V_CC = $(am__v_CC_$(V))" as one that
        expands a macro with the funny name am__v_CC_$(V instead of the
        desired name am__v_CC_1 or am__v_CC_0, and since the funny macro
        is not defined the line is equivalent to "AM_V_CC = )"; this
        inserts a stray ")" when $(AM_V_CC) is used, which eventually
        causes 'make' to fail.

        The basic idea is that instead of generating Makefile.in lines like
        "AM_V_CC = $(am__v_CC_$(V))", we generate
        "AM_V_CC = $(am__v_CC_@AM_V@)".  We then AC_SUBST $(V) for @AM_V@
        in the usual case where `make' supports nested variables,
        and substitute 1 (or 0) otherwise.  Similarly for usages like
        $(am__v_CC_$(AM_DEFAULT_VERBOSITY)).

        With this change, make implementations that doesn't grasp nested
        variable expansions will still be able to run Makefiles generated
        using the silent-rules option.  They won't allow the user to
        override the make verbosity at runtime through redefinition of
        $(V) (as in "make V=0"); but this is still an improvement over not
        being able to work at all.

        * NEWS: Document this.
        * automake.in (define_verbose_var): When defining the variables,
        use @AM_V@ rather than $(V), and use @AM_DEFAULT_V@ rather than
        $(AM_DEFAULT_VERBOSITY).
        * doc/automake.texi (Automake silent-rules Option): Explain new system.
        * m4/silent.m4 (AM_SILENT_RULES): Check whether `make' supports
        nested variables, and substitute AM_V and AM_DEFAULT_V accordingly.
        * tests/silent-nested-vars.test: New test.
        * tests/Makefile.am (TESTS): Add it.

        gitignore: use only one .gitignore file, in the top-level directory
        * doc/.gitignore, doc/amhello/.gitignore, lib/Automake/.gitignore,
        lib/Automake/tests/.gitignore, tests/.gitignore: Deleted, their
        contents merged into ...
        * .gitignore: ... this top-level file.  Since we are at it, improve
        it by anchoring files where it makes sense.

        tests: one more fixlet for gettext macros requirement
        * tests/gettext-macros.test (configure.in): Add calls to
        AC_INIT and AC_PROG_CC, to avoid a spurious failure in the
        later aclocal invocation.
        Luckily, this wart wasn't causing any spurious SKIP or FAIL,
        but only the redundant addition to the `-Wno-syntax' option
        to some aclocal invocations in the gettext tests.

        tests: fix handling of gettext macros requirement

        The code introduced in the earlier change `v1.11-581-gb7d67d5'
        and aimed at automatically fetching all the .m4 files provided by
        gettext has proven inadequate, since it hasn't managed to truly
        and always get *all* the required .m4 files.  For example, it has
        failed to fetch the file `intldir.m4' (present in gettext 0.18.1,
        and where the macro `AM_GNU_GETTEXT_INTL_SUBDIR' is defined),
        which in turn has caused spurious SKIPs of at least the test
        `gettext3.test'.

        The reason for this debacle is that autopoint looks at the version
        specified in AM_GNU_GETTEXT_VERSION to decide which version of the
        gettext infrastructure to bring in; since we were unconditionally
        specifying the older 0.10.35 version, the newer `.m4' files weren't
        brought in.

        * tests/gettext-macros.test: In AM_GNU_GETTEXT_VERSION, instead
        of unconditionally specifying the older 0.10.35 version, specify
        the version of the available `gettextize' or `autopoint' program,
        dynamically extracted with the help of ...
        (extract_program_version):... this new function, and saved ...
        ($autopoint_version): ... in this new variable.

2011-12-23  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tests: automatically handle deps also for generated tests
        * tests/gen-testsuite-part: The test scripts are now scanned for
        automatic dependency generation *after* the auto-generated tests
        have been created, so they too will be scanned.  It is a little
        tricky to ensure that the freshly-generated tests are correctly
        scanned, and we do that with the help of ...
        (@generated_tests): ... this new variable.
        Other related minor changes and refactorings.

        tests: auto-generate deps for tests requiring libtool/gettext
        * tests/gen-testsuite-part: Tests requiring libtool (or related
        programs) will need libtool-provided m4 macros, so they should
        be run after `libtool-macros.test'.  Similarly for gettext tests.
        So, generate proper declarations of such dependencies.
        * tests/Makefile.am: Remove now-unneeded hand-written declaration
        of those dependencies.

        tests: remove FIXME comments from tricks to pacify syntax checks
        Originally, I myself had insisted on adding those "FIXME" comments
        near every unusual construct or use of "creative quoting" whose
        only purpose was to avoid false positive from out syntax checks.
        I did that with the expectation that we could have easily and soon
        added a whitelisting capability to our maintainer-specific syntax
        checks.  This hasn't been the case unfortunately, and now those
        "FIXME" in the comments are just distracting noise, making it more
        difficult to grep the test cases for stuff that could really use a
        fix or an improvement.  So just get rid of them.

        tests: avoid spurious failure of libtool and gettext tests

        On Solaris 10 (and presumably earlier), /bin/sh trips up on
        here-documents that contains a command substitution *and* are
        fed to a shell function:

          # All as expected.
          $ cat <<END
          `pwd`
          END
          /home/stefano
          $ echo status = $?
          status = 0

          # An apparently innocuous function ...
          $ kitty () { cat; }
          # ... but hilarity ensues!
          $ kitty <<END
          `pwd`
          END
          /tmp/sh137723: cannot open
          $ echo status = $?
          status = 1

        We need to work around this misbehaviour in a couple of our
        tests (whose failures where causing cascading failures in a
        lot of other tests).

        * tests/gettext-macros.test: Avoid the use of command substitution
        in a here-document passed to the `indent' function, by using the
        `echo' builtin instead.
        * tests/libtool-macros.test: Likewise.

        regex: deprecate the obsolete macro AM_WITH_REGEX
        This is a backport of commit v1.11-433-g37b0aee.
        Today, practically nobody uses the GNU rx library, which, according
        to its own website <http://www.gnu.org/software/rx/rx.html>, has
        been "decommissioned".  Consequently, the automake-provided macro
        AM_WITH_REGEX is not used nor required anymore.  Deprecate it, so
        that it will be possible to safely remove it in the next major
        automake version.
        * m4/regex.m4 (AM_WITH_REGEX): Give a warning of the class
        `obsolete' when this macro is used.
        * doc/automake.texi (Public Macros): Move description of
        `AM_WITH_REGEX' from here ...
        (Obsolete Macros): ... to here, and declare it as obsolete
        and "to be removed in a future version".
        * tests/regex-obsolete.test: New test.

        maint: distribute .xz tarballs, not .bz2 ones
        Many GNU packages are moving towards xz-compressed tarballs, so
        let's follow suit, by dropping the creation and distribution of

        tests: better handling of gettext and libtool requirements

        This change fixes automake bug#9807.

        Before this change, the automake testsuite only looked for the
        `.m4' files containing libtool and gettext macros definitions in
        the directory `${prefix}/share/aclocal' (and in the directories
        specified by the `dirlist' file in there, if any), where ${prefix}
        was the configure-time automake installation prefix (defaulting
        to `/usr/local').

        This approach had various shortcomings and disadvantages.  Let's
        briefly describe the three major ones.

        First, on most GNU/Linux systems, a libtool or gettext installed
        from distro-provided packages (e.g., by dpkg on Debian/Ubuntu, or
        by rmp on RedHat/Fedora) would have `/usr', not `/usr/local', as
        its ${prefix}; so, trying to run the automake testsuite with a
        simple "./configure && make && make check" would have failed to
        execute the libtool and gettext tests on most GNU/Linux distros.
        It's true that it was quite easy to work around this issue, by
        creating a proper `/usr/local/share/aclocal/dirlist' file with
        an entry pointing to `/usr/share/aclocal' (a workaround in fact
        used by most automake developers); but the typical user wasn't
        aware of the necessity of this trick, so the libtool and gettext
        tests was usually skipped on testsuite runs "in the wild", thus
        needlessly reducing coverage.

        Second, the older testsuite behaviour made more difficult for
        the developers to run the testsuite with non-default libtool or
        gettext.  For example, assume the developer is working on a system
        that has a default libtool version 1.5 installed in the /usr/local
        hierarchy; to improve coverage, the developer installs also a more
        modern libtool version, say 2.4, in its home directory, let's say
        in ~/libtool-2.4; he then tries to run the automake testsuite with
        this more modern libtool by doing an (apparently) simple:
          $ PATH=$HOME/libtool-2.4:$PATH make check
        But the automake testsuite would still look for libtool macros in
        /usr/local/share/aclocal, not in ~/libtool-2.4/share/aclocal, so
        the wrong version of the macros would be picked up, and the tests
        would either fail spuriously or (which would be worse) pass without
        truly covering the libtool version the developers was thinking to
        be testing with.
        Worse again, the automake testsuite would *unconditionally* look
        for libtool macros in /usr/local/share/aclocal, so even something
        like:
          $ export ACLOCAL_PATH=$HOME/libtool-2.4/share/aclocal
          $ PATH=$HOME/libtool-2.4:$PATH make check
        wouldn't work.

        Third and last, during a "make distcheck", automake is configured
        with a ${prefix} pointing to a proper subdirectory of the build
        directory (usually `pwd`/_inst), which gets created on-the-fly;
        in this case, with the old approach, the automake testsuite never
        found the libtool and gettext macro files, ans so the libtool and
        gettext tests was *always* skipped in a "make distcheck".

        * tests/libtool-macros.test: New helper test, looking (with the
        help of the `libtoolize' script) for libtool macro files required
        by most libtool tests, and making them easily accessible.
        * tests/gettext-macros.test: New helper test, looking (with the
        help of the `libtoolize' script) for libtool macro files required
        by most libtool tests, and making them easily accessible.
        * tests/defs.in: Update to make it rely on the results and setups
        of `libtool-macros.test' and `gettext-macros.test'.
        * tests/Makefile.am: Declare dependency of all the logs of libtool
        tests from `libtool-macros.log', and all the logs of gettext tests
        from `gettext-macros.log'.
        (TESTS): Add the new tests.

        tests: report useful system information in 'test-suite.log'
        It has already happened various times that a user has run the
        automake testsuite, experienced a failure, read the messages
        telling him "See tests/test-suite.log" and "Please report to
        bug-automake@gnu.org", and done exactly that -- sending us only
        the contents of `tests/test-suite.log', which are usually not
        enough to start debugging the reported failure.  So we have to
        ask him for more details, and usually also for the `config.log'
        file generated by configure.  It's time to fix this recurring
        feedback inefficiency.  We do so by creating a dummy test case
        that takes care of copying the contents of `config.log', plus
        other useful system information, in the final `test-suite.log'.
        * tests/get-sysconf.test: New test, gathering system information
        and then always terminating with a SKIP, so that its output gets
        copied in `test-suite.log'.
        * tests/Makefile.am (TESTS): Add it.

        maint: snapshots from `maint' are still development snapshots
        The maintenance-oriented development line in the `maint' branch,
        while being usually pretty stable and 99% backward-compatible,
        is not always right off production-quality; but until now, the
        Automake package version declared in configure.ac hid this fact,
        since it appeared to be the version of a stable release (e.g.,
        11.1).  Fix this.
        * configure.ac (AC_INIT): Bump version to "1.11.0a".

        the user.
        * README-alpha: Delete, it's obsolete now (and in fact this file
        hasn't been touched in eleven years, since release 1.4b or so).

        devel: help in comparing Makefile.in from different commits
        Now that the generated Makefile.in, configure and aclocal.m4 files
        are no longer committed in Automake's git repository, a simple
        "git diff" or "git log" no longer shows if and how a change in
        Automake results in changes to the Makefile.in files and/or
        configure script of its own build system.  Still, the ability to
        peek so easily at such differences has proved itself quite useful
        in the past, often revealing inconsistencies and blunders, and
        sometimes even bugs; so it would be a pity to lose that altogether.
        With this change, we add a new maintainer recipe that re-introduces
        much of that capability, by generating and comparing on the fly the
        Makefile.in, configure and aclocal.m4 derived from two arbitrary
        commits of the Automake repository.
        * Makefile.am (autodiffs, compare-autodiffs): New phony targets.

2011-12-22  Stefano Lattarini  <stefano.lattarini@gmail.com>

        repo: don't commit generated files in the git repository anymore
        It has been quite some time since autoconf and libtool have stopped
        committing the generated autotools files in their git repositories,
        with no significant ill effects we're aware of.  It's true that the
        autoconf bootstrap process has now the minor annoyance that a
        pre-installed autoconf is required to complete it; but luckily
        automake will not have a similar annoyance, since our bootstrap
        script take care, through some hoops, to use the very automake and
        aclocal versions from the current git checkout to generate the
        required aclocal.m4 and Makefile.in files.  In fact, this has been
        a necessity also in the past, because automake has been known to
        use in its own build system new development features that hadn't
        been present in any previously released automake distribution.
        * .gitignore: Ignore configure, aclocal.m4, and all the
        Makefile.in files.
        * configure.ac (AC_PREREQ): New macro call, to require the
        latest autoconf (2.68 for the moment).

        missing: don't try to re-run tar with a munged command line
        * lib/missing: If the default `tar' program fails with the given
        arguments, and GNU tar is not available, don't try to re-run the
        default `tar' with a munged command line (e.g., ditching possibly
        unportable options), as that could be subtly alter the intended
        semantics (and maybe even create a somewhat corrupted tarball).
        Also, it's worth noting that the main purpose of the `missing'
        script is to allow a non-developer to build the package in the
        face of slightly-skewed timestamps, not to provide wrappers for
        all the maintainer tools -- so we don't have to try too hard
        when `missing' is just called to wrap `tar'.
        * tests/missing-tar.test: New test.
        * tests/Makefile.am (TESTS): Add it.

2011-12-22  Stefano Lattarini  <stefano.lattarini@gmail.com>

        missing: inform the user if GNU tar is called
        * lib/missing: If the code trying to run GNU tar is reached, it
        means that the previous attempt to run the default tar program
        has failed, very likely producing some error message.  At this
        point, just running GNU tar without further comments might be
        confusing.

2011-12-22  Stefano Lattarini  <stefano.lattarini@gmail.com>

        missing: if GNU tar exists but fails when called, give up
        * lib/missing: If the code trying to run GNU tar is reached,
        don't continue if the invoked GNU tar program fails, as there
        is little point in doing so (and can even be confusing and
        counter-productive).

        missing: miscellaneous fixlets
        * lib/missing: Some shells, such as Solaris or FreeBSD /bin/sh,

        Therefore, where we have to silently check whether a program
        exists, perform redirections on a subshell.

        yacc/lex tests: avoid too much failures with FreeBSD make

        In various Yacc/Lex tests, we used to run "make distcheck" commands
        whose value was mostly dubious, and, even when it was there, was
        very, very little.  The presence of these extra distchecks had two
        disadvantages: it slowed down our already-too-slow testsuite even
        more, and, much worse, caused a lot of extra failures with FreeBSD,
        all due to automake bug#7884, which is already exposed by the test
        case `yacc-dist-nobuild.test'.

        We can improve this situation by simply removing "make distcheck"
        calls from a few testcases, or making them conditional to the use
        of GNU make.

        dist-xz, dist-bzip2: don't hard-code -9, honor envvar settings
        Before the present change, automake-generated `dist-xz' rule used
        a hard-coded `xz -9'.  That was a problem because on this front,
        xz differs from gzip and bzip2.  While the latter two don't incur
        any run-time decompression penalty for using a higher compression
        level, specifying -9 with xz imposes a potentially fatal virtual
        memory requirement on any client that wants to decompress your
        tar.xz file.
        People have complained that a tarball compressed with -9 cannot
        be uncompressed in a low-memory environment (wrt-based embedded).
        Hence, instead of defaulting to -9, which is useful only for very
        large tarballs, it defaults to -e (equivalent to -6e).  This
        limits the default memory requirements imposed on decompressors,
        yet still gives very good compression ratios.
        * lib/am/distdir.am (dist-xz): Do not hard-code xz's -9: that made
        it impossible to override.  Actually don't default to -9, either,
        since that induced inordinately large virtual memory usage when
        merely decompressing.  Instead, use its XZ_OPT envvar, defaulting
        to -e if not defined.  Suggested by Lasse Collin.
        (dist-bzip2): Similarly, do not hard-code -9, but do continue to
        use -9 by default.  Honor the BZIP2 envvar.

        tests: fix spurious failures due to missing 'yywrap()' function

        The AC_PROG_LEX Autoconf macro does not diagnose a failure to find
        the "lex library" expected to provide a `yywrap' function (function
        which is required to link most lex-generated programs).  On the
        contrary, when all the link attempts (i.e., with `-ll' and `-lfl')
        fail, configure declares that no lex library is needed, and simply
        proceeds with the configuration process -- only for the build to
        possibly fail later, at make time.

        This behaviour is intended; the Autoconf manual reads:
         ``You are encouraged to use Flex in your sources, since it is
           both more pleasant to use than plain Lex and the C source it
           produces is portable.  In order to ensure portability, however,
           you must either provide a function `yywrap' or, if you don't use
           it (e.g., your scanner has no `#include'-like feature), simply
           include a `%noyywrap' statement in the scanner's source.''

        This AC_PROG_LEX behaviour is causing some spurious failures of
        the Automake testsuite in environments which lack a proper library
        providing `yywrap' (this happens for example on Fedora-based
        systems).   The proper workaround is to simply provide a fall-back
        implementation of `yywrap' in our lexers.

        See also partially-overlapping commit `v1.11-871-geb147a1' (from
        the 'testsuite-work' branch), which was motivated by similar
        spurious failures experienced when cross-compiling.

        `extra-portability' warning is).  Other minor extensions.  Remove
        some redundant, verbose comments about the expected diagnostic.

        info: allow user to inhibit creation/update of '${infodir}/dir'
        With this change, we allow the user to request the install-info
        rules not to update the `${infodir}/dir' file, by setting the
        environment variable `AM_UPDATE_INFO_DIR' to the value "no".
        This is especially useful to distro packagers, and is a definite
        improvement over our previous hack of looking whether the
        `install-info' program was the Debian or GNU version -- hack
        which had been silently broken with recent versions of debian
        install-info BTW (probably since dpkg 1.15.4, 2009-09-06).
        This change fixes automake bug#9773.  See also Debian Bug#543992.
        * lib/am/texinfos.am: Don't look anymore at the output of
        `install-info --version' to decide whether to use it to update

        variable `AM_UPDATE_INFO_DIR'.
        * tests/install-info-dir.test: New test.
        * tests/Makefile.am (TESTS): Add it.

        This change partly reverts commit "Create subdirs for generated

        That commit had caused the bugs #8485 and #8526.  Since we are
        nearing the bug-fixing automake release 1.11.2, the safest policy

        tests: fix spurious failures due to missing 'yywrap()' function

        The AC_PROG_LEX Autoconf macro does not diagnose a failure to find
        the "lex library" expected to provide a `yywrap' function (function
        which is required to link most lex-generated programs).  On the
        contrary, when all the link attempts (i.e., with `-ll' and `-lfl')
        fail, configure declares that no lex library is needed, and simply
        proceeds with the configuration process -- only for the build to
        possibly fail later, at make time.

        This behaviour is intended; the Autoconf manual reads:
         ``You are encouraged to use Flex in your sources, since it is
           both more pleasant to use than plain Lex and the C source it
           produces is portable.  In order to ensure portability, however,
           you must either provide a function `yywrap' or, if you don't use
           it (e.g., your scanner has no `#include'-like feature), simply
           include a `%noyywrap' statement in the scanner's source.''

        This AC_PROG_LEX behaviour is causing some spurious failures of
        the Automake testsuite in environments which lack a proper library
        providing `yywrap' (this happens for example on Fedora-based
        systems).   The proper workaround is to simply provide a fall-back
        implementation of `yywrap' in our lexers.

        See also partially-overlapping commit `v1.11-871-geb147a1' (from
        the 'testsuite-work' branch), which was motivated by similar
        spurious failures experienced when cross-compiling.

        <http://lists.gnu.org/archive/html/automake-patches/2011-10/msg00092.html>

        * tests/parallel-tests3.test: To ensure that the serial run of
        the dummy testsuite is still ongoing when the parallel run has
        terminated, use `kill -0', not a bare `kill'.  This will prevent
        a testsuite crash on NetBSD 5.1, and a testsuite hang on FreeBSD
        8.2.  Also, since we are at it, try harder to avoid possible

        dist: separate auxiliary file instantiation from DIST_COMMON update
        This change simplifies the automake internals dealing with the
        checking, copying and distributing of required auxiliary files.
        With this change, a required auxiliary file is *unconditionally*
        added to the contents of the DIST_COMMON variable in the generated
        Makefile.in, before checking whether it exists, or trying to copy
        it (if `--add-missing' is in use).  This shouldn't be a problem,
        since if the checking or copying of the file fails, automake will
        bail out, the Makefile.in won't be created, and thus its content
        will not matter.  OK, this is not completely true when threaded
        automake is in use, but then, such a situation was also possible
        before this patch, so no regression here, which is enough for us.
        This change is the first of a series of steps aimed at fixing
        the regression introduced in threaded automake usage by commit
        `v1.11-1219-g326ecba'.
        * automake.in (require_file_internal): Add the required file to
        DIST_COMMON unconditionally.
        * tests/missing-auxfile-stops-makefiles-creation.test: New test.
        * tests/Makefile.am (TESTS): Add it.

        This change fixes automake bug#9651.
        * automake.in (handle_dist): Files whose distribution is required
        by configure.ac are now correctly distributed even if the build-aux
        directory coincides with the top-level directory.
        * tests/Makefile.am (XFAIL_TESTS): Remove `dist-auxfile.test'.
        * NEWS: Update.

2011-10-08  Stefano Lattarini  <stefano.lattarini@gmail.com>

        dist: simplify automake code accordingly to the previous changes
        After the previous change `v1.11-1219-g326ecba', every Makefile.am
        requiring a file in the "config auxdir" will cause it to be listed
        in the DIST_COMMON variable of the corresponding generated
        Makefile.in, not only of the top-level Makefile.in.  Thus we don't
        need to worry anymore about trying to distribute files in the
        config auxdir from the top-level Makefile or the Makefile in
        config auxdir (if any).  This allows us to carry out some useful
        simplifications in the automake script.
        This will however cause some changes in the generated Makefile;
        for example, if the `PROGRAMS' primary is used only in a subdir
        Makefile.am, the `depcomp' script will be distributed only by
        `subdir/Makefile', not by the top-level Makefile.  This change
        can be seen as an internal detail though, and definitely warranted
        by the nice simplifications the current commit provides.
        * automake.in ($automake_will_process_aux_dir): Variable removed.
        (scan_autoconf_files): Adjust and simplify.
        (handle_makefiles_threaded): Likewise.
        (get_number_of_threads): Likewise.
        (require_file_internal): Likewise.
        (maybe_push_required_file): Its return value is not used anymore,
        so return nothing.  Add special handling for distributed files from
        `$config_libobj_dir'.  Also, catch "this can't happen" situations,
        and abort accordingly.  Fix function description to better fit its
        new role.
        * tests/libobj19.test: Extend to also check situations where the
        Makefile.am using $(LIBOBJS) is not the top-level one.
        * tests/distcom6.test: Delete, merged into ...
        * tests/distcom2.test: ... this test, which has been update to
        account for the changed automake semantics.
        * tests/Makefile.am (TESTS): Update.
        * NEWS: Update.

2011-10-08  Stefano Lattarini  <stefano.lattarini@gmail.com>

        dist: auxiliary files can be distributed from subdir Makefiles
        With this change, we make it possible for a subdir Makefile.am
        to distribute files in the config auxdir; while this means that
        some files might be copied multiple times, it simplify some logic
        in the automake script, and fix at least one important bug.  In
        fact, before this change, the auxiliary script `test-driver' was
        not being distributed as expected when TESTS was defined only in
        a subdir Makefile (which is a pretty common setup indeed).  Now
        this does not happen anymore: so the present change fixes automake
        bug#9546.
        Another welcome collateral effect is that `dist-auxfile-2.test'
        now passes.
        OTOH, the present changes *breaks threaded automake*.  The reason
        is that automake needs to serialize file installations spawned
        by `--add-missing' (this isn't for cosmetic reasons, but is
        really needed to avoid possible race conditions and botched output
        files).  Currently the code that installs required files is
        intertwined with the code that declares the DIST_COMMON variables;
        so, upon de-serialization, the definition of DIST_COMMON might get
        emitted in the wrong Makefile.in.
        Some follow-up refactoring in automake will soon take care of
        remedying this situation.  For the moment, we just declare some
        "parallel-am" tests as xfailing.
        * automake.in (maybe_push_required_file): Add ad-hoc handling for
        the case where the directory part of the required file is different
        from the subdir where the current Makefile.am resides, but is equal
        to the "config-aux directory" ($config_auxdir).  This is needed to
        allow a construct in a non-top-level Makefile.am to require a file
        in the config-aux directory.
        * tests/test-driver-is-distributed.test: Extend and adjust.  This
        test now passes.
        * tests/java-compile-run-nested.test: Call automake with the `-a'
        option to ensure that the `test-driver' auxiliary script gets
        correctly installed.  This test now passes.
        * tests/distcom-subdir.test: New test.
        * tests/dist-readonly.test: Likewise.
        * tests/dist-repeated.test: Likewise.
        * tests/dist-auxdir-many-subdirs.test: Likewise.

        parallel-tests: don't allow @substitutions@ in TEST_EXTENSIONS
        Even after the last commit `v1.11-476-g90bea64', the checks
        performed by automake on entries in $(TEST_EXTENSIONS) tried to
        allow for @substitited@ stuff.  This however ends up allowing
        quite brittle setups, which, most importantly, are of no real
        practical usefulness anyway.  So it's better to just disallow
        @substitutions@ in TEST_EXTENSIONS altogether, offering a clear
        error message, instead of risking weird bugs and unexpected
        behaviors in the generated Makefile.in.
        * automake.in ($TEST_EXTENSION_PATTERN): Turned from a regular
        expression ...
        (is_valid_test_extension): ... into this subroutine.  Don't allow
        generic @substitutions@ anymore (possibly making an exception for
        `@EXEEXT@' under the proper circumstances).
        * tests/test-extensions.test: Adjust and extend.  This test does
        not cause any internal error in automake anymore now.

        tap/awk: improve comments about Korn shell signal handling issues
        * lib/tap-driver.sh: Link an Austin Group discussion about how
        shells are allowed, and even encouraged, to set the special
        variable `$?' to values greater than 256 to report termination

        workarounds for unusual korn shell signals' propagation.

        tap/awk: account for unusual korn shell signal handling behaviour
        This change has been motivated by a testsuite failure on Debian

        * lib/tap-driver.sh: Temporarily ignore some common signals when

        in Korn shells that propagate to themselves signals that have
        killed a child process.

        tap/awk: handle exit statuses > 256 (seen on few korn shells)
        Some Korn shells, when a child process die due to signal number
        n, can leave in $? an exit status of 256+n instead of the more
        standard 128+n.  Apparently, both behaviours are allowed by
        POSIX, so be prepared to handle them both.
        This change has been motivated by a testsuite failure on Debian
        with the AT&T Korn Shell version 93u-1.
        * lib/tap-driver.sh (get_test_exit_message): Handle the described
        Korn Shell behaviour too.

        tests: more granularity in variables for tools overriding
        Among the other things, this change makes it possible to use, at
        the same time, an autoconf version in the automake testsuite and
        another one in the automake build system; even more importantly, it
        makes it possible to use, say, a non-GNU make implementation in the
        test scripts, while at the same time using GNU make to drive the
        execution of the automake's test suite.
        * tests/defs-static.in (TEX, EGREP, FGREP, SHELL, PERL, MAKE,
        AUTOCONF, AUTOM4TE, AUTORECONF, AUTOHEADER, AUTOUPDATE,
        original_AUTOMAKE, original_ACLOCAL): Allow and prefer overriding
        through corresponding `AM_TESTSUITE_..' variables; for example,
        $GREP can now be overridden by an exported `$AM_TESTSUITE_GREP'

        * Makefile.am (sc_tests_tap_plan): It's OK for auto-generated
        TAP tests that sources an hand-written one not to declare a TAP
        plan: the sourced test will do so.
        * tests/Makefile.am (checked_test_extensions): Don't define
        anymore, the default value `$(TEST_EXTENSIONS)' is correct now.

2011-09-06  Stefano Lattarini  <stefano.lattarini@gmail.com>

        aclocal: more granularity in acdir overriding
        Before this change, using the `--acdir' option caused aclocal to
        redefine both the directory of automake-provided m4 macros and the
        directory of third-party system-wide m4 macros.  With this change,
        we deprecate the `--acdir' aclocal option, and introduce two new
        options `--automake-acdir' and `--system-acdir', to allow for more
        granularity.
        * aclocal.in (@automake_includes, @system_includes,
        @user_includes): Fix and extend comments.
        (usage): Update.
        (handle_acdir_option): New function.
        (parse_arguments): Recognize new options `--system-acdir' and
        `automake-acdir', and handle `--acdir' using the new function
        above.  Simplify logic by assuming that the directory of
        third-party system-wide m4 files always exists.
        * tests/aclocal.in: Update to use the new options, instead of
        the deprecated. `--acdir'.
        * m4/dirlist: Move ...
        * m4/acdir/dirlist: ... here.
        * m4/Makefile.am (EXTRA_DIST): Update.
        (m4datadir): Rename ...
        (automake_acdir): ... to this.  Accordingly, ...
        (dist_m4data_DATA): ... rename this ...
        (dist_automake_ac_DATA): ... to this.
        (system_acdir): New, directory.
        (dist_system_ac_DATA): New, defined to an empty value; this will
        ensure that the $(system_acdir) directory will be created by
        "make install".
        * tests/aclocal.test: Remove check about the `--print-ac-dir'
        option of aclocal, it has been moved into ...
        * tests/aclocal-print-acdir.test: ... this new test, and quite
        extended.

        testsuite: revamp generation of autogenerated tests
        With this change, we make generated tests be real scripts again
        -- albeit only thin layers around the tests they wrap.  It turned
        out that the apparently clever tricks we played by having lots
        of custom (and auto-generated) `..._LOG_COMPILER' variables and
        by having the tests in $(wrap_TESTS) not being real on-file-system
        scripts caused more pain and confusion than expected, for only
        marginal gains.  Also, that previous setup didn't interact very
        well with "make check RECHECK_LOGS=", since the log files for
        the "wrappee" tests were always considered out-of-date (which in
        hindsight is natural, since these log files depended on wrappee
        tests that didn't exist -- and weren't created).  And finally, it
        wasn't possible to easily and naturally run the wrappee tests
        from the command line -- definitely harmful for debugging and
        sanity checking.
        * tests/gen-wrap-tests: Deleted, its role subsumed into ...
        * tests/gen-tests-deps: ... this script, with the help of
        (unindent, atomic_write, build_matcher, write_wrapper_script,
        %test_generators): ... these new functions and variables.
        Other few minor fixlets and improvements.
        * tests/wrap-tests.sh: Delete, not needed anymore.
        * tests/Makefile.am ($(srcdir)/wrap-tests.am): Don't generate
        nor include anymore.
        (EXTRA_DIST): Update.
        (wrap_TESTS): Renamed to ...
        (generated_TESTS): ... this.
        ($(generated_TESTS)): Must have the same dependencies of
        `$(srcdir)/tests-deps.am'.
        Other minor related reordering and adjustments.
        * bootstrap: Do not generate `wrap-tests.am' anymore.
        * tests/.gitignore (wrap-tests.am): Don't ignore anymore.
        (*-w.test, *-w.tap): Ignore.
        * tests/README: Update paragraph on automatically-generated
        tests.

        ($(srcdir)/tests-deps.am): New rule.
        (include $(srcdir)/tests-deps.am): New inclusion.
        Remove hand-written dependencies for tests.  Other related
        updates.
        * tests/list-of-tests (tap_with_common_setup_TESTS,
        tap_other_TESTS): Delete, their content merged back into ...

        tests: avoid spurious failure due to bug in older TAP::Parser
        Older TAP::Parser versions (e.g., 3.10) erroneously convert a test

        * lib/tap-driver.pl (trap_perl_warnings_and_errors): Do not use
        the three-args version of the `open' builtin, it is not well
        supported by older perl versions (at least perl 5.6.2).
        (start): Add a no-op statement to pacify a "possible typo ... used
        only once" perl warning.

        tap/perl: be more portable to older TAP::Parser versions
        * lib/tap-driver.pl (start): Do not call the `ignore_exit' method
        on our TAP parser: it is not supported in older TAP::Parser
        versions (e.g., 3.10), and is not really required by our usage of
        the parser object.

        automake: fix regression due to de-ansification support removal
        The last change `v1.11-947-g136b489' removed code that automake
        was using to decide whether binary objects were built by the
        generated Makefile.in, so that it could avoid to emit unneeded
        code when this was not the case.  Re-introduce such code in a
        less-obfuscated form, and add a test to ensure we don't regress
        again.
        * automake.in ($must_handle_compiled_objects): New global
        variable, telling whether the generated Makefile has to build
        compiled objects.
        (initialize_per_input): Reset it.
        (handle_programs, handle_libraries, handle_ltlibraries): Set
        it to a true value when required.
        (handle_compile): Don't generate any code if the variable
        `$must_handle_compiled_objects' is not set to a true value.
        * tests/no-extra-makefile-code.test: New test.

        tests: better respect of TAP usage in wrapped tests
        * tests/gen-wrap-tests: Partial rewrite to take into account the
        possibility that the wrapped test uses the TAP protocol.  This
        complicates the code quite a bit, but is essential to ensure real
        correctness in all the wrapped scripts.

2011-08-29  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tests: list of tests placed in a separate Makefile fragment
        This change allows us to easily use make instead of by-hand (and
        more fragile) grepping to extract the list of hand-written tests
        from our Makefiles.
        * bootstrap (BOOTSTRAP_MAKE): New variable.
        Use it to run make in order to extract the list of hand-written

        tests: some minor fixlets w.r.t. TAP-based tests
        The variable that is used by our test scripts to decide whether
        they are "plain" or TAP-based is `using_tap'; however, some
        peripheral sanity checks and sanitization code in our testsuite
        were erroneously using the `use_tap' variable instead.  Fix that.
        * tests/Makefile.am (AM_TESTS_ENVIRONMENT): Nullify `using_tap',
        not `use_tap'.
        * tests/defs-static.in: Check that `using_tap', not `use_tap',
        is not exported.
        * tests/self-check-env-sanitize.test: Update.

2011-08-29  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tests: avoid re-running a test with the 'parallel-tests' option
        * tests/backcompat5.test (parallel_tests): Define to "no", to
        prevent the generation of a sibling test script that uses the
        'parallel-tests' driver.  That would be useless anyway, since
        we manually override the contents of configure.in, thus clobbering
        the `parallel-tests' option in AM_INIT_AUTOMAKE.
        Fix a typo in comments since we are at it.

        testsuite: different test scripts cannot share the same basename
        If two test scripts have the same basename, they will end up
        sharing the same log file, leading to all sort of undefined and
        undesired behaviours.  Add a Makefile check verifying that this
        is not the case.
        * tests/test-logs-repeated.test: New test, verifying previously
        unspecified semantics (in the definition of $(TEST_LOGS) from
        $(TESTS)) that we use in our new check.
        * tests/Makefile.am (TESTS): Update.
        (check-no-repeated-test-name): New .PHONY check.
        (check-local): Depend on it.

        tests: fix spurious failure for awk implementation of TAP driver
        * tests/tap-realtime.test: The awk+shell implementation of the TAP
        driver must "read ahead" of one line in order to catch the exit
        status of the test script it runs.  So, in the TAP-producer script
        here, be sure to echo one "dummy" line after each TAP result line
        in order not to cause false positives.

        tap/awk: allow escaping of TAP directives
        * lib/tap-driver.sh (setup_result_obj): Handle escaping of TAP
        directives in a way tat is (mostly) compatible by what is done
        by the TAP::Parser module.
        With this change, the tests `tap-escape-directive.test' and
        `tap-escape-directive-2.test' now also pass with the shell/awk
        implementation of the TAP driver.

2011-08-25  Stefano Lattarini  <stefano.lattarini@gmail.com>

        coverage: more about escaping of TAP directives
        * tests/tap-escape-directive.test: Make grepping of testsuite
        progress output slightly stricter.
        * tests/tap-escape-directive-2.test: New test (failing with the
        awk implementation of the TAP driver).
        * tests/Makefile.am (tap_with_common_setup_tests): Update.

2011-08-25  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tap: improve syncing between awk+shell and perl implementations
        * lib/tap-driver.pl (stringify_test_result): Renamed ...
        (stringify_result_obj): ... to this.  Break up a clause in the
        long "if/elsif/.../else" construct to avoid unaesthetic line
        breaks and to be more synced with the sibling function in
        `tap-driver.sh'.  Rename the `$result', `$PASS' and `$FAIL'
        variables to respectively `$result_obj', `$COOKED_PASS' and
        `$COOKED_FAIL', for clarity and better syncing.
        (handle_tap_test): Renamed  ...
        (handle_tap_result): ... to this, and change the name of the
        `$test' local variable to `$result_obj'.
        (extract_comment): Reimplement using the simpler `index' and
        `substr' builtins, rather than with more advanced uses of
        regular expressions.
        (%test_results, @test_results): Renamed respectively ...
        (%test_results_seen, @test_results_list): ... to these, and
        related adjustments throughout the `TEST_RESULTS' block.
        (main, get_global_test_result): Refactor and do some cosmetic
        changes to make these functions clearer and better synced with
        sibling code in `tap-driver.sh'.
        Other minor cosmetic and typo fixes.
        * lib/tap-driver.sh (extract_tap_comment): Remove outdated
        "FIXME" comments.
        (get_global_test_result): Small reordering to make it better
        synced with its sibling function in `tap-driver.pl'.
        (stringify_result_obj): Consistently use `result_obj' as the
        parameter name.
        Other minor cosmetic and typo fixes.

        tap/perl: don't redirect perl warnings/errors to log files
        With this change, the test `tap-driver-stderr.test' also passes
        with the perl implementation of the TAP driver.
        * lib/tap-driver.pl (start): Save the original stderr into the
        `OLDERR' file handle, and call ...
        (trap_perl_warnings_and_errors): ... this new function, trapping
        the `__WARN__' and `__DIE__' "pseudo-signals" to ensure that the
        warning and error messages goes to that original stderr stream.
        Since we are at it, be sure to prepend all possible "die" message
        with the name of the script as given by the `$ME' variable.

2011-08-25  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tap/perl: add copyright notice, version string, and emacs stuff
        * lib/tap-driver.pl: Add proper copyright notice and bug reporting
        address.  Remove obsolete heading comments.  Add trailing comments
        for emacs w.r.t. code-formatting rules and automatic updating of
        the date-based script version saved into the `$VERSION' variable.
        ($VERSION): Define to the current UTC date.

        tap/awk: don't redirect awk stderr to log files
        * lib/tap-driver.sh: Handle the file descriptors redirections
        more smartly, to avoid sending error messages from awk (about
        e.g. syntax or I/O errors) to the log files instead that to the
        console.
        * tests/tap-driver-stderr.test: New test, verifying the improved
        driver behaviour.  Notice that this test still fails when using
        the perl implementation of the TAP driver.
        * tests/Makefile.am (tap_other_tests): Update.

2011-08-24  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tap/awk: remove obsolete "FIXME" comment

        a "controlled" production environment.

2011-08-22  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tap/awk: handle non-zero exit status from the test command
        * lib/tap-driver.sh (get_test_exit_message): New function in the

        or at least a good guess of it.
        (write_test_results): Use it, reporting an ERROR result if it
        detects that the test program exited with a non-zero status.
        * tests/tap-signal.test: Account for the differences in the
        error messages generated by the awk and perl TAP drivers.  Fix

2011-08-22  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tap/awk: refactor for future changes
        * lib/tap-driver.sh: Rewrite the awk script so that the parsing

        seems to be more portable to Solaris 10 XPG4 awk.

2011-08-22  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tap/awk: support Solaris /usr/bin/nawk
        * lib/tap-driver.sh (close_or_die): Remove, the use of the `close'
        builtin in there was confusing /usr/bin/nawk from Solaris 10 into
        a syntax error.
        (write_test_results): Simply use `close' on the `*.trs' file, that
        should be enough.

2011-08-21  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tap/awk: correctly extract message from SKIP plans
        * lib/tap-driver.sh (/^1\.\.0+[ \t]*#/): Add a forgotten `?' to
        the regex used to extract the skip message from a "1..0" TAP plan.
        * tests/planskip.test: Check for the just-fixed bug.
        * tests/tap-planskip-unplanned-corner.test: Don't be too strict
        w.r.t. the formatting of the "skip whole test" message, to avoid
        failing due to bugs irrelevant for this test (like the one just
        fixed).

2011-08-21  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tap/awk: support colorized output
        * lib/tap-driver.sh: Pass definition of colors to the BEGIN block
        of the awk script, using ...
        ($init_colors): ... this new variable, which supersedes ...
        ($red, $grn, $lgn, $blu, $mgn, $std): ... these variables, which
        have been consequently removed.
        ($color_tests): We don't have to pass this anymore to the awk
        script, so do not convert it to a numeric boolean.
        (decorate_result): Implement for real.
        With this change, the test 'tap-color.test' now passes.

2011-08-21  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tap: real (but still incomplete) awk implementation of TAP driver
        * lib/tap-driver.sh: Add an incomplete, but mostly working,
        implementation of a TAP parser and driver in awk.  It doesn't yet
        support colorized output, fetching of exit status from test
        programs, nor a way to escape TAP directives in TAP result lines,
        but passes all the tests of TAP support in the automake testsuite,
        apart from the following ones:
          - tap-color.test
          - tap-escape-directive.test
          - tap-exit.test
          - tap-missing-plan-and-bad-exit.test
          - tap-passthrough-exit.test
          - tap-planskip-badexit.test
          - tap-planskip-unplanned-corner.test
          - tap-signal.test
        Tested on Debian GNU/Linux with GNU awk 3.1.7 and 3.0.2, "original
        awk" 2010-05-23-1, and mawk 1.3.3-15 (with which also the test
        `tap-realtime.test' fails, in addition to those listed above).

        coverage: some more tests on corner cases of TAP support
        * tests/tap-no-spurious.test: Extend checks verifying that a line

        TAP result.
        * tests/tap-no-spurious-numbers.test: New test, checking that our
        TAP driver doesn't spuriously recognize as TAP result numbers what
        is not (even if it seems pretty close).
        * tests/tap-negative-numbers.test: New test, checking that our
        TAP driver doesn't spuriously recognize negative TAP result
        numbers, but correctly interprets them as test descriptions
        instead.
        * tests/tap-plan-leading-zero.test, tap-numbers-leading-zero.test:
        New tests, checking how our driver fares in recognizing numbers
        with leading zeroes in TAP results or TAP plans.
        * tests/tap-planskip-malformed.test: New test, checking that a
        malformed TAP plan is not recognized as a valid plan.
        * tests/tap-plan-whitespace.test: New test, checking that a TAP
        plan line with trailing whitespace is recognized and handled
        correctly.
        * tests/Makefile.am (tap_with_common_setup_tests): Update.

        testsuite: various fixlets and tweakings
        * tests/seenc.test: Make grepping of automake stderr stricter.
        Add a trailing `:' command.
        * tests/symlink.test: Likewise.  Also, define `$am_create_testdir'
        to "empty" to avoid bringing in unused auxiliary files (only to
        have to remove them right away), and use proper m4 quoting in
        `configure.in'.
        * tests/vpath.test: Make grepping of generated `Makefile.in'
        slightly stricter.  Prefer trailing `:' over trailing `Exit 0'.
        * tests/suffix6c.test: Unset OBJEXT to avoid interferences from
        the environment.
        * tests/suffix12.test: Do not whitespace-indent `##' comments
        when they are embedded in a makefile rule: having them indented
        is not part of the Automake API, and might cause failures with
        e.g., Tru64 make.
        * tests/syntax.test: Simplify the `Makefile.am' to ensure that
        automake doesn't fail for the wrong reasons.  Make grepping of
        automake stderr slightly stricter.
        * tests/test-harness-vpath-rewrite.test: Remove useless variable

2011-08-16  Stefano Lattarini  <stefano.lattarini@gmail.com>

        parallel-tests: no more spurious successes for FreeBSD make
        Work around a bug of FreeBSD make bug that was causing the
        automake-generated "check" target to complete with success
        even if some tests failed; this happened only when FreeBSD
        make was run in concurrent mode (as in, e.g., "make -j2
        check").  The bug is not present in NetBSD make.
        This change fixes automake bug#9245:
         <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9245>
        See also FreeBSD PR bin/159730:
         <http://www.freebsd.org/cgi/query-pr.cgi?pr=159730>
        * lib/am/check.am [%?PARALLEL_TESTS%] $(TEST_SUITE_LOG): Use a
        more "safe" (and apparently redundant) idiom to exit with error,
        so that the non-zero exit status is picked up also by FreeBSD
        make when it's running in concurrent mode.
        * NEWS: Update.
        * tests/check-concurrency-bug9245.test: New test.
        * tests/Makefile.am (TESTS): Update.

        tap: correctly handle string "0" in TAP messages
        * lib/tap-driver.pl (is_null_string): New function, can be used
        to determine whether a given string variable is empty or undefined.
        Useful to avoid pitfalls like:
          if ($message) { print "$message\n"; }
        which wouldn't print anything if $message is the literal "0".
        (handle_tap_test, handle_tap_plan, handle_tap_bailout): Use it,
        to avoid missing messages composed only by a literal "0" in TAP
        result descriptions and in skip, todo and bailout explanations.
        * tests/tap-message-0.test: Enhance.
        * tests/Makefile.am (XFAIL_TESTS): Remove it, it passes now.

        tap: add a dummy TAP driver script implemented in shell + awk
        The user can also now decide which implementation of the TAP driver
        to use in the testsuite by defining the `$am_tap_implementation'
        variable to either "perl" or "shell".  Future enhancements will
        allow the testsuite to automatically run the test scripts on TAP
        support with both the TAP driver implementations, to improve
        coverage.
        * tests/defs (fetch_tap_driver): Honor the `$am_tap_implementation'
        variable to decide which implementation of the TAP driver to fetch.
        ($am_tap_implementation): Default to "perl".
        * tests/tap-common-setup.test: Do not fetch the TAP driver, the
        code in tap-setup.sh does that already (and respecting runtime
        overriding of `$am_tap_implementation').
        * lib/tap-driver: Renamed ...
        * lib/tap-driver.pl: ... to this, and ...

        it, rewrite it to make it easier to add new entries in the future.

        testsuite: refactor tests on TAP support in view of future changes
        * tests/defs (fetch_tap_driver): New subroutine; it fetches the
        automake-provided TAP driver from the `lib/' directory into the
        current directory, and edits its shebang line so that it will be
        run with the perl interpreter determined at configure time.
        * tests/tap-setup.sh: Use it.
        * tests/tap-common-setup.test: There's no need to AC_SUBST `PERL'
        anymore, nor to use it in the Makefile to run the TAP driver.
        Also, use the `fetch_tap_driver' function instead of copying the
        `tap-driver' auxiliary script directly.

        (Throughout the file): Use more complex semantics for `$plan_seen',
        which now also remember whether the plan that has been seen is an
        "early" or "late" plan; in turn, this makes ...
        ($tap_stopped): ... this variable redundant; remove it.
        (handle_tap_plan): Adjust to avoid producing spurious or confusing
        error messages about extra or mismatched "late" TAP plans.
        * tests/tap-plan-corned.test: Adjust and extend.
        * tests/tap-color.test: Likewise.

        telling whether a "Bail out!" directive has been seen or not.
        (handle_tap_bailout): This function does not anymore stop the
        reading from TAP stream; instead, it sets `$bailed_out' to a
        true value, so that only the subsequent parsing of the input
        TAP stream is stopped.
        (finish): Remove, no more needed, its contents inlined into ...
        (main): ... this function, with related adjustments in the code
        flow.
        (get_test_exit_message): Do not "flush" the input TAP stream
        to fetch the exit status of test script, it is not anymore
        required.  Add a sanity check.
        * tests/tap-bailout-and-logging.test: New test.

2011-08-12  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tap: non-zero exit status after "Bail out!" should not be reported
        This new behaviour is more consistent with that of the `prove'
        utility.  Also, experience with the use of TAP in the Automake's
        own test suite has shown that reporting non-zero exit status from
        a script after it has issued a "Bail out!" directive is mostly
        redundant, more introducing noise rather than conveying useful
        information.
        * lib/tap-driver (finish): Inline the part of it that was getting
        the script exit status ...
        (main): ... in here.
        * tests/tap-bailout-badexit.test: New test.
        * tests/Makefile.am (tap_with_common_setup_tests): Update.

2011-08-11  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tap: a "plan with SKIP" after test results is an error
        This new behaviour is both more natural and more consistent with
        that of the `prove' utility.
        * lib/tap-driver (handle_tap_plan): Do not stop TAP parsing when
        a "plan with SKIP" line (e.g., "1..0 # SKIP") is encountered, and
        do not print a "SKIP" line if some TAP result has already been
        seen.

        test harness: avoid possible fork bomb
        This fixes a regression w.r.t. the master branch, exposed by
        test 'parallel-tests-fork-bomb.test'.
        * lib/am/check.am (am--redo-logs): Detect possible infinite
        recursion due to a test log in $(TEST_LOGS) being the same
        as $(TEST_SUITE_LOG).

        coverage: possible infinite recursion in the test harness
        Motivated by a regression in the 'test-protocols' branch.
        * tests/parallel-tests-fork-bomb.test: New test, checking that
        if $(TEST_SUITE_LOG) is in $(TEST_LOGS), we obtain a diagnosed
        error rather than a make hang or a fork bomb.
        * tests/Makefile.am (TESTS): Update.

        testsuite: avoid confusing SKIP messages for errored tests
        * tests/defs [$use_tap] (exit trap): Don't print the test plan
        in case the client script exited with a non-zero status.  This
        avoids the display of redundant "SKIP" messages for tests with
        lazy plans that error out before any test is run.

2011-08-13  Stefano Lattarini  <stefano.lattarini@gmail.com>

        testsuite: keep more debugging info around in 'add-missing.tap'
        * tests/add-missing.tap: Use a different directory for each test,
        so that in case of failure more information is kept around.
        Since we are at it, remove redundant TAP diagnostic, and define
        `$am_create_testdir' to "empty" to avoid bringing in unused
        auxiliary files.

2011-08-13  Stefano Lattarini  <stefano.lattarini@gmail.com>

        which keep more granular counts.
        ($tap_pass_count_: New variable.
        * tests/defs (exit trap): Adjust and simplify accordingly.

2011-08-13  Stefano Lattarini  <stefano.lattarini@gmail.com>

        testsuite: fixlets and improvements in two long TAP-based tests
        * tests/depmod.tap: Clean up the subdirectories used by tests that
        passed, to avoid ending up with a too big test directory.  This is
        especially important since, on each and every system, at least some
        tests in this script are expected to be skipped (which ones exactly
        depends on the system), thus causing the test directory not to be
        removed when the script terminates.
        * tests/instspc.tap: Likewise (with the difference that tests here
        are not expected to be skipped, but to xfail).  Give more explicit
        error message in case of setup failure.  Skip the proper number of
        tests when required, to avoid spurious errors due to mismatched
        plan.  Also, really avoid to run the unsupported test cases when
        the need to skip them is detected.

        Problem detected by the `sc_tests_make_without_am_makeflags'
        maintainer check.

2011-08-09  Stefano Lattarini  <stefano.lattarini@gmail.com>

        testsuite: improvements to our shell TAP library and APIs
        These improvements impact only the Automake's own testsuite.
        * tests/tap-functions.sh (plan_): Allow new special arguments
        "unknown" a.k.a. "later" and "lazy" a.k.a. "now".  Perform
        sanity check the given arguments.  Adjust incorrect comments.
        (lazy_plan_): Removed, superseded by the new version of `plan_'.
        (not): New function, run a command and inverts its exit status.
        (ok_, not_ok_, skip_): These are just shorthands for common
        `result_' usages.
        (xfail_, xpass_, reset_test_count_): Removed, they are not used,
        nor does a legitimate use for them seem in sight.
        (not): New function, to run a command inverting its exit status.
        (command_not_ok_): Removed, superseded by `command_ok_' + `not'.
        (command_ok_): Extended to accept TAP directives.
        * tests/defs (trap): Don't use `late_plan_' anymore, use
        `plan_ "now"' instead.
        * tests/ac-output-old.tap: Update to take advantage of the new
        APIs.
        * tests/self-check-env-sanitize.tap: Likewise.

2011-08-09  Stefano Lattarini  <stefano.lattarini@gmail.com>

        testsuite: convert some `suffix*' tests to TAP
        This will allow us to explicitly declare some expected failures
        involving Solaris make as such, instead of partly papering over
        them with skips and partly letting them fail too loudly.
        * tests/suffix-chain.test: Rename ...
        * tests/suffix-chain.tap: ... to this, and convert to the use of
        TAP.  Also, fix some bugs since we are at it, and ...

        See automake bug#7670 and bug#7824.
        * tests/defs (make_can_chain_suffix_rules): New function, tell
        whether the make implementation in use can chain suffix rules
        automatically or not.
        * tests/suffix3.test: Use it to avoid issuing calls to make that
        are unportable to make implementations that are not smart enough
        to chain suffix rules automatically.
        * tests/suffix8.test: Use it to avoid issuing calls to make that

2011-08-09  Stefano Lattarini  <stefano.lattarini@gmail.com>

        gitignore: more use of anchors

        in its subdirectories.
        * doc/.gitignore, doc/amhello/.gitignore, lib/Automake/.gitignore,
        lib/Automake/tests/.gitignore, tests/.gitignore: Likewise.  Also,
        where needed, add new entries that were once implied by the
        non-anchored entries in the upper-level `.gitignore' files.

2011-08-09  Stefano Lattarini  <stefano.lattarini@gmail.com>

        self tests: avoid spurious output on console, and related fixlets
        * tests/self-check-cleanup.test: Set `$stderr_fileno_' to `2'
        in the self tests, to avoid spurious diagnostic on console.
        * tests/self-check-exit.tap: Only unset `am_explicit_skips' and
        `$stderr_fileno_' in the self tests, not at the global level, it
        is more correct.
        ($init): New variable, to reduce code duplication.
        Some refactoring and adjustments to the name of the tests.

2011-08-09  Stefano Lattarini  <stefano.lattarini@gmail.com>

        test defs: few more sanity checks
        * tests/defs: Catch some more (very unlikely) set-up or internal
        errors, and diagnose them explicitly.  This is intended mostly
        to be a theoretic-only improvement.

2011-08-09  Stefano Lattarini  <stefano.lattarini@gmail.com>

        test defs: really make them "set -e" clean
        Motivated by a spurious failure of test `instsh3-w.shtst' on
        Solaris 10.
        * tests/defs: Make really "set -e" clean, to avoid spurious
        failures in case this file is sourced by a test script that has
        already set the `errexit' flag.  To be sure we don't regress,
        move the `set -e' call much earlier, and make the comment telling
        about the expected "set -e" cleanliness more loud and outstanding.

2011-08-09  Stefano Lattarini  <stefano.lattarini@gmail.com>

        self tests: register an expected failures with Solaris /bin/sh
        Solaris 10 /bin/sh erroneously exit with success right away when
        the following three conditions are met at the same time:
         1. the `errexit' flag is active,
         2. an exit trap is installed, and
         3. a non-existing command is issued.
        * tests/self-exit.tap: When that bug is detected, issue an XFAIL
        rather than a FAIL.  Since we are at it, improve by avoiding
        creation of stray temporary files when testing for non-executable
        commands.

2011-08-09  Stefano Lattarini  <stefano.lattarini@gmail.com>

        gitignore: update and improve for the testsuite files
        * tests/.gitignore: Don't ignore temporary partial log files,

        anymore.  Anchor all the remaining patterns.

2011-08-09  Stefano Lattarini  <stefano.lattarini@gmail.com>

        self tests: some new uses of TAP, few extensions

        Set `$stderr_fileno_' to `2', to avoid spurious messages on the

2011-08-09  Stefano Lattarini  <stefano.lattarini@gmail.com>

        test defs: test directory creation more configurable
        After this change, the individual tests will be able to tell
        `./defs' whether or not to create a temporary test directory
        for them, and if yes, whether or not to pre-populate it.
        * tests/defs: Only create the temporary test directory if the
        variable `$am_create_testdir' is not set to "no".  In this
        case, only pre-populate it if that variable is not set to
        `$empty'.
        * tests/defs-static.in: Check that `$am_create_testdir' is not
        exported in the environment.
        * tests/self-check-env-sanitize.test: Update.
        * tests/self-check-dir.test: Extend, and make deeper and more

        * tests/README (Section "Writing test cases" subsection "Do"):
        Update.
        * tests/autodist.test: Set `$am_create_testdir' instead of

        testsuite: more uses of the `seq_' function
        * tests/parallel-tests-exit-statuses.test: Use the `seq_' function

2011-08-08  Stefano Lattarini  <stefano.lattarini@gmail.com>

        test defs: small cleanups and tweakings
        * tests/defs: Where possible, prefer `framework_failure_' or
        `fatal_' to `Exit 99'.  Try to catch more possible hard errors
        and setup failures.  Do not hide expected error messages.  Avoid
        a couple of forks when copying files from `$(top_srcdir)/lib'.
        ($signal): Remove, no more needed.

2011-08-08  Stefano Lattarini  <stefano.lattarini@gmail.com>

        testsuite: improve interface for giving early TAP plan
        Since commit `v1.11-976-g4740f56', an early TAP plan can also be
        specified after input lines have already been seen, as long as
        no one of them is a TAP result line.  We can now take advantage
        of this in our own testsuite, allowing the TAP-based scripts to
        specify their earlier plan after having included `./defs'.  In
        particular, this offers the benefit of allowing those scripts to
        issue a "skip all" plan (e.g., "1..0 # SKIP reason ...") after
        the inclusion of `./defs', which wasn't possible with the older
        interface (introduced in commit `v1.11-1114-g0286308').
        * tests/defs: Don't try to call `plan_' if `$planned' is defined,
        the calling scripts can do that directly now.
        * tests/ac-output-old.tap: Use `plan_' directly instead of
        setting `$planned' before including `./defs'.
        * tests/automake-cmdline.tap: Likewise.
        * tests/depmod.tap: Likewise.
        * tests/instspc.tap: Likewise.

2011-08-08  Stefano Lattarini  <stefano.lattarini@gmail.com>

        test defs: fix skip directives to work also with TAP-based tests
        * test/defs: Use `skip_all_', not `skip_', to issue a skip of the

        minimize the risk of unwanted VPATH rewrites.
        (check-TESTS): Likewise, and normalize trailing whitespace

        Bugs exposed by test cases `check6-p.test' and `check7-p.test'.

2011-08-08  Stefano Lattarini  <stefano.lattarini@gmail.com>

        test harness: "make -n check" works correctly with Solaris make
        To avoid some recipes being executed with "make -n", we used the
        trick of issuing recursive make calls not directly with $(MAKE),
        but with a simple indirection instead:
          ...
          am__stealth_MAKE = $(MAKE)
          ...
          target:
              ... $(am__stealth_MAKE) ...
          ...
        This hack worked with GNU make, but, unfortunately, not with
        Solaris make.  The present change removes the hack, and uses more
        proper idioms to avoid unwanted recipe executions with "make -n".
        Bug exposed by test case `parallel-tests-dry-run.test'.
        * lib/am/check.am (am__stealth_MAKE): Remove, no more used.
        (.log.trs): Break recipe in multiple shell invocations.
        ($(TEST_SUITE_LOG)): Likewise, and move some corner-case parts of
        the recipe to ...
        (am--redo-logs): ... this new internal helper .PHONY target.

        liberally with AM_DISTCHECK_CONFIGURE_FLAGS, since the line breaks
        so introduced, in conjunction with single quotes, might confuse
        Solaris make.

        exposing the problem fixed by this change

        parallel-tests: work around Solaris XPG4 make segfault
        Issue exposed by test `posixsubst-tests-p.test', and similar to
        the problem solved by commit `v1.11-159-ge7aa360'.
        * lib/am/check.am [%?PARALLEL_TESTS%] (check-TESTS): Trim trailing
        whitespace from $list, to avoid triggering a nasty bug (potential
        segfault) on Solaris XPG4 make and Heirloom make.

        testsuite: fix weird spurious failure with Solaris /bin/sh
        Solaris /bin/sh, when killed with a SIGTERM or SIGINT signal, can
        apparently end up exiting with exit status 208, instead of leaving
        the correct wide exit status to the parent.  See:
         <http://dbaspot.com/shell/396118-bourne-shell-exit-code-term.html>
        Work around this incompatibility.
        * tap-signal.test: Look for the above Solaris bug.

        * tests/parallel-tests-log-override-recheck.test: Filter make
        output before grepping it, for make implementations that, like
        Solaris' one, print the whole of the failed recipe on failure.

        testsuite: fix two spurious failures on Solaris make
        * tests/tests-environment-and-log-compiler.test: Do not fail if

        (peek_tap_line, unget_tap_line, @tap_lines): Remove, they're not
        used anymore.
        (TAP_PEEKING): Block deleted, all its subroutines and variables
        having been removed.

2011-08-07  Stefano Lattarini  <stefano.lattarini@gmail.com>

        testsuite: fix spurious failure in a test on TAP support
        * tests/tap-passthrough-exit.test: When the `--ignore-exit' flag
        of the TAP driver is used, don't look for a message reporting the
        non-zero exit statuses of tests in the log files; such message is
        not expected to be there anymore.  Related simplifications.

2011-08-07  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tap: plan location is more liberal w.r.t. non-TAP lines
        With this change, only lines that are TAP results will matter
        w.r.t. the position of the TAP plan in the input; for example,
        this input:
          this is a non-TAP line
          # and this a TAP diagnostic line
          1..1
          ok 1
        was considered to be an error, diagnosed with a message "test
        plan in middle of output"; as effect of the current change, such
        input is now valid.  This is more consistent with the behaviour
        of the `prove' utility.
        * lib/tap-driver ($lineno): Removed, no more needed.
        ($tap_stopped): New global variable.
        (stringify_test_result): Return "ERROR" if a TAP result is found
        when `$tap_stopped' is set to true.
        (handle_tap_test): Diagnose TAP results that comes after a late
        plan.  Add a couple of blank lines, for clarity.
        (handle_tap_plan): Set `$tap_stopped' to true after a late plan
        is encountered.  Do not complain anymore for extra non-TAP lines
        preceding or following the plan.  Adjust comments.
        (main): Don't increment $lineno anymore.
        * tests/tap-plan.test: Extend a bit, and remove stale comment.
        * tests/tap-color.test: Adjust.
        * tests/tap-passthrough.test: Likewise.
        * tests/tap-plan-corner.test: Adjust and extend.

2011-08-07  Stefano Lattarini  <stefano.lattarini@gmail.com>

        test defs: get name of TAP-using tests correctly
        This change fixes the names of the temporary directories used
        by the TAP-based tests (e.g., test `foo.tap' now uses `foo.dir'
        rather than `foo.tap.dir'); more importantly, this make the
        variable `$destdir' defined in `tests/defs' usable also in the
        TAP tests.
        ($me): Also strip the any `.tap' suffix from the name of the
        test.

2011-08-07  Stefano Lattarini  <stefano.lattarini@gmail.com>

        testsuite: TAP tests properly decide when to remove tempdirs
        Before this change, the TAP tests in the Automake testsuite were
        removing the temporary test directory even when they failed or
        were skipped, thus making debugging more difficult.
        * tests/tap-functions.sh (incr_tap_count): Removed, superseded
        by ...
        (incr_): ... this function, which can increment the value of any
        variable passed to it.
        (result_):  Updated to use `incr_' instead of the now-removed
        `incr_tap_count_'.  Keep count of failures, xfailures, xpasses,
        and skips, using ...
        ($tap_skip_count_, $tap_bad_count, _$tap_xfail_count_): ...
        these new variables.
        * tests/defs (trap): Try to use their values to decide whether
        the temporary directory being used by the test script should be
        removed or not.  Other code reorganizations.  And move the code
        for the removal of the temporary directory out to ...
        (rm_rf_): ... this new subroutine.
        (Main code): Use that instead of duplicating the code.

        testsuite: improve and refactor our custom TAP shell library
        This change is mostly done in preparation for the next one.
        * tests/tap-functions.sh (result_with_directive_): Merge into ...
        (result_): ... this function, which has been greatly extended and
        improved in various ways.
        (ok_, not_ok_, skip_, xfail_, xpass_): Adjust.
        Adjust comments.  Remove an extra empty line.
        * tests/instspc.tap: Use the new improved interface of `result_'.
        * tests/tap-bad-prog.tap: Likewise.

2011-08-07  Stefano Lattarini  <stefano.lattarini@gmail.com>

        testsuite: update "user interface" description in tests/README
        * tests/README (Subsection "Interpretation"): Mention the "ERROR"
        outcome.
        (Subsection "Getting details from failures"): Don't tell that the
        test scripts can be run directly, this is not 100% true; anymore;
        instead ...
        (Subsection "About the tests"): ... use this new subsection to
        explain how to run the tests (either simple or TAP-based) by hand.
        (Subsection "Supported shells"): Extend to refer to TAP tests too.

2011-08-07  Stefano Lattarini  <stefano.lattarini@gmail.com>

        testsuite: TAP tests can have early plan now
        * tests/defs: When using TAP, allow the user to specify the number
        of tests through the `$planned' variable.
        (trap): Do not print the auto-generated plan if an explicit one
        has already been printed.
        * tests/defs-static.in: Complain and bail out if the `$planned'
        variable is exported in the environment.  Reformat the code to
        facilitate future additions.
        * tests/Makefile.am (TESTS_ENVIRONMENT): Neutralize `$planned'.
        * tests/self-check-env-sanitize.test: Update.
        * tests/ac-output-old.tap: Give an explicit TAP plan, by defining
        `$planned' just before including `./defs'.

        * tests/automake-cmdline.tap: Likewise.
        * tests/tap-bad-prog.tap: Likewise.

        plan, and tell why.

2011-08-07  Stefano Lattarini  <stefano.lattarini@gmail.com>

        testsuite: run autogenerated tests with $(LOG_COMPILER) too
        This change enhances consistency in the testsuite.
        * tests/Makefile.am: Some cosmetic reordering, to keep the
        definition of FOO_LOG_COMPILER near to the place where `.foo'
        is added to $(TEST_EXTENSIONS).
        (PTEST_LOG_COMPILER): Run `$(srcdir)/parallel-tests.sh' with
        `$(LOG_COMPILER)', not with `$(SHELL)'.
        (SHTST_LOG_COMPILER): Likewise.

2011-08-07  Stefano Lattarini  <stefano.lattarini@gmail.com>

        testsuite: run TAP and "plain" tests with the same $(LOG_COMPILER)
        With this change, it will be easier to override, at make time, the
        shell used to run the tests.
        * tests/Makefile.am (LOG_COMPILER): Define to `$(SHELL)'.
        (TEST_LOG_COMPILER): Re-define to `$(LOG_COMPILER)'.
        (TAP_LOG_COMPILER): Likewise.

2011-08-06  Stefano Lattarini  <stefano.lattarini@gmail.com>

        testsuite: run TAP-based tests explicitly with $(SHELL)
        * tests/Makefile.am (TAP_LOG_COMPILER): Define to `$(SHELL)'.

2011-08-06  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tap driver: handle signals received by the tests being run
        * lib/tap-driver (get_test_exit_message): Also deal with signals,
        by using the `wait' method of the TAP::Parser object instead of
        the `exit' method.  This required the use of the standard perl
        module `POSIX'.
        * doc/automake.texi (Use TAP with the Automake test harness):
        Document that `--ignore-exit' has effect also on terminating
        signals.  Add a "synchronizing" comment that references the tests
        'tap-exit.test' and 'tap-signal.test'.
        * tests/tap-signal.test: Extend and adjust.

2011-08-06  Stefano Lattarini  <stefano.lattarini@gmail.com>

        test driver: a preparatory refactoring (2)
        * lib/tap-driver (finish): Move code to fetch the message about
        the exit status of the test being run to ...
        (get_test_exit_message): ... this new subroutine.

2011-08-06  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tap driver: a preparatory refactoring (1)
        * lib/tap-driver (finish): Do not flush the TAP stream nor
        fetch the exit status of the TAP producer if running with
        the `--ignore-exit' option.  Obviously, don't try to write
        such exit status in the test log anymore.

2011-08-06  Stefano Lattarini  <stefano.lattarini@gmail.com>

        cosmetics: typofix in the name of a function in the TAP driver
        * lib/tap-driver (testuite_error): Renamed ...
        (testsuite_error): ... to this, and minor related reformatting.

2011-08-06  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tap: scripts with a SKIP plan but with exit status != 0 must error
        This change has been motivated by Automake's own testsuite.  Some
        TAP tests there were erroring out (due to unexpected, unhandled
        failures) before having encountered TAP result, so that the
        simple-minded shell library implementing TAP generation ended up
        printing a "1..0" trailing test plan; this caused the script to be
        reported as a SKIP rather than an ERROR -- a nasty false negative.
        * lib/tap-driver: Add prototypes for each subroutine, to free up
        the order in which they can be defined and called.
        (main): Move the code checking for a bad exit status of the TAP
        producer ...
        (finish): ... here, and flush the TAP stream to ensure that the
        parser always obtains the producer's exit status.
        * tests/tap-skip-whole-badexit.test: New test.
        * tests/Makefile.am (tap_with_common_setup_tests): Add it.

2011-08-06  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tap: fix whitespace munging of diagnostic messages
        * lib/tap-driver (extract_tap_comment): Pass the `g' flag to the
        substitution operator, to strip also trailing whitespaces.  Fixes
        a failure in test `tap-whitespace-normalization.test'.

2011-08-06  Stefano Lattarini  <stefano.lattarini@gmail.com>

        testsuite: refactor and cleanup 'instspc.tap'

        (define_problematic_string): Likewise.  Also, rename the special
        arguments `build-fail' and 'install-fail' to respectively
        `builddir-fail' and `destdir-fail', and other related changes.
        (Test data definition): Adapt.
        ($instspc_xfail_builds_list): Renamed ...

        Add some explicative and "FIXME" comments.

        testsuite: use TAP for `depmod*' tests, related simplifications
        * tests/depmod-tests.sh: Delete this complex and multifarious
        script, moving all it checks it used to perform into ...
        * tests/depmod.tap: ... this TAP-based test script.  And extend
        it quite a bit, since the new form of the test was papering over
        some pre-existing failures (this was due to the fact that the
        values used for the VPATH were shorter in the new test script).
        * tests/depmod-data.test: Deleted.

        testsuite: do fd redirections with $(AM_TESTS_FD_REDIRECT)
        * tests/Makefile.am: The redirections of file descriptors needed
        by our test scripts is now done using the $(AM_TESTS_FD_REDIRECT)
        variable (the new blessed way since commit `v1.11-906-gb9e9d54'),
        not using an hack involving $(AM_TESTS_ENVIRONMENT).  This has
        the further benefit of allowing the use of $(TESTS_ENVIRONMENT)
        again on part of the users.
        * tests/Makefile.am (AM_TESTS_ENVIRONMENT): Remove redirection of
        file descriptors.
        (AM_TESTS_FD_REDIRECT): Redirect file descriptor 9 to original

        testsuite: use custom TAP diagnostic in our own tests
        This change allow us to easily and transparently avoid spurious
        TAP diagnostic in our own testsuite, with the help of the new
        `--diagnostic-string' option of our TAP test driver.
        * tests/Makefile.am (TAP_LOG_DRIVER_FLAGS): Also pass option
        `--diagnostic-string' with value `#%#' (necessarily obtained
        through some shell indirections).
        * tests/tap-functions.sh (diag_): Assume that the string denoting

2011-08-05  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tap: new option to change the string designating TAP diagnostic
        Here we introduce a new option `--diagnostic-string' in our TAP
        test driver, that allows the user to specify which string should
        denote the beginning of a TAP diagnostic line.  This change is
        not gratuitous, nor result if over-engineering: it is motivated
        by real issues that have emerged during the use of TAP in the
        Automake's own testsuite (see the commit `v1.11-1082-g9b967c2'
        "testsuite: yet more use of TAP, and related extensions").
        * doc/automake.texi (Use TAP with Automake test harness): Document
        the new option.
        (Incompatibilities with other TAP parsers and drivers): Report it
        as a potential source of incompatibility.
        * lib/tap-driver ($diag_string): New global variable, defaulting
        to "#", and whose value can be changed ...
        (Getopt::Long::GetOptions): ... by the newly recognized option
        `--diagnostic-string'.
        (handle_tap_comment): Subroutine removed, some of its simple logic
        inlined ...
        (main): ... in here, where now ...

        check.

2011-08-05  Stefano Lattarini  <stefano.lattarini@gmail.com>

        check: update comments to reflect recent heavy changes
        * lib/am/check.am [%?PARALLEL_TESTS%]: Update the comments to
        reflect the recent changes.  Remove quite many comments that
        were merely duplicating excerpts from the Automake manual.

2011-08-05  Stefano Lattarini  <stefano.lattarini@gmail.com>

        check: small cleanups and refactorings in test harness and drivers
        * lib/tap-driver (yn): New subroutine, converts a boolean value to
        a "yes" or "no" string.
        (write_test_results): Use it, and related reformatting.
        * lib/test-driver (trap): Also remove the `.trs' file on signals,
        for extra safety.
        (fatal): Remove this function, it's never used.
        ($logfile, $trsfile): Renamed ...
        ($log_file, $trs_file): ... to these, for clarity, and in order to
        be more consistent with the `tap-driver' script.
        Improve a couple of comments.
        * automake.in (handle_tests): Don't define anymore the now-obsolete
        make macro `$(TEST_LOGS_TMP)', nor add it to the list of files to
        be removed upon "make mostlyclean".
        * lib/am/check.am ($(TEST_SUITE_LOG)): New shell function `f_ok',
        tells whether a path refers to an existing, regular, readable file.
        Use it throughout.
        (recheck): Be safer w.r.t. make implementation that run recipes
        with `errexit' shell flag active.

2011-08-05  Stefano Lattarini  <stefano.lattarini@gmail.com>

        testsuite: use AM_TESTS_FD_REDIRECT where appropriate
        * parallel-tests-interrupt.test: Use AM_TESTS_FD_REDIRECT, not
        AM_TESTS_ENVIRONMENT, to define file descriptors' redirection
        for "make check".  Fix botched comment.

2011-08-05  Stefano Lattarini  <stefano.lattarini@gmail.com>

        docs: some fixlets in documentation on testsuites support
        * doc/automake.texi (Script-based Testsuites): Rename node ...
        (Scripts-based Testsuites): ... to this.  Break overly long lines
        in an example (were causing problems with PDF output).
        (Parallel Test Harness): Don't intend paragraphs that come after
        examples or bulleted list.
        (Overview of Custom Test Drivers Support): Fix typo s/the the/the/.
        (Declaring Custom Test Drivers): When giving an aside, prefer comma

        (API for Custom Test Drivers): Remove a sentence that was basically
        duplicated from the previous subsection.
        (Command-line arguments for test drivers): Don't intend paragraph
        coming after an itemized list.  Clarify wording and fix grammaros.

2011-08-04  Stefano Lattarini  <stefano.lattarini@gmail.com>

        test harness: be aware of more metadata, simplify test drivers
        * lib/am/check.am ($(TEST_SUITE_LOG)):  When producing the
        global test log, take into account the new metadata field
        `:global-test-result:, to write nicely formatted RST section
        titles, instead of leaving this chore to the individual test
        drivers.
        (am_rst_section): Re-introduce this variable, as removed in
        commit `v1.11-870-ga27c9c4'.
        * lib/test-driver, lib/tap-driver: Write the global test result
        as metadata in the `.trs' file, not as (part of) a formatted RST
        subsection title in the `.log' file.  Related simplifications;
        in particular, get rid of temporary files usage.
        * doc/automake.texi (Log files generation and test results
        recording): Document the new metadata.
        * tests/check12.test: Update.

2011-08-03  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tap: check that also a trailing TAP plan can hold a skip directive
        * tests/tap-skip-whole-lastline.test: New test.
        * tests/Makefile.am (tap_with_common_setup_tests): Add it.

2011-08-04  Stefano Lattarini  <stefano.lattarini@gmail.com>

        testsuite: more correct names for a couple of tests

2011-08-04  Stefano Lattarini  <stefano.lattarini@gmail.com>

        testsuite: fix another spurious failure
        * tests/parallel-tests-ext-driver.test: Name out custom/dummy
        log compilers as `foo-compiler' rather `foo-driver'; not only
        this is less confusing, it also avoids errors due to the dummy
        log compiler `test-driver' overriding the `test-driver' helper
        script installed by Automake.
        * tests/parallel-tests-ext-driver-prog.test: Adjust heading
        comments.

2011-08-04  Stefano Lattarini  <stefano.lattarini@gmail.com>

        testsuite: fix a spurious failure
        * tests/parallel-tests-ext-driver.test: Exporting of environment
        variables directly from $(LOG_COMPILER) variables is not allowed
        anymore.  Adjust to this.

2011-08-04  Stefano Lattarini  <stefano.lattarini@gmail.com>

        testsuite: yet more use of TAP, and related extensions
        * tests/defs (show_): New function, display the contents of one or
        more files on stdout, with bells & whistles (both for cosmetic and
        practical reasons, the latter aimed at avoiding spurious TAP
        diagnostic).
        (AUTOMAKE_run): Extend and adapt to make it compatible with TAP
        based tests.  Since we are at it, make its implementation more
        namespace-safe, and improve its command-line interface.
        (AUTOMAKE_fails): Adapt to the new command-line interface of
        `AUTOMAKE_run'.
        * tests/add-missing.test: Renamed ...
        * tests/add-missing.tap: ... to this, and converted to the use
        of the TAP protocol, and of the new `show_' function.
        * tests/automake.test: Renamed ...
        * tests/automake-cmdline.tap: ... to this, and converted to the
        use of the TAP protocol.

        of `AUTOMAKE_run'.

        reported in the testsuite progress output.

2011-08-03  Stefano Lattarini  <stefano.lattarini@gmail.com>

        maintcheck: fix more maintainer-check failures
        * tests/test-driver-custom-no-html.test (no-rst): Use `EOF',
        not `EoL', as the here-document delimiter.
        * tests/test-trs-basic.test: Use `cat + here-doc' rather
        than `echo' when creating the dummy test scripts, to please
        maintainer-check.
        * tests/test-trs-recover.test: Use creative quoting where
        needed, to please maintainer-check.

2011-08-03  Stefano Lattarini  <stefano.lattarini@gmail.com>

        maintcheck: fix maintainer-check failures, both real and spurious
        * tests/amhello-binpkg.test: Use "$MAKE", not bare "make".
        * Makefile.am (sc_perl_local): Also allow perl special variable
        `$~' to be localized.  And be slightly laxer in the regexp, to
        allow for usages like "local $_ = $foo;".
        (sc_tests_overriding_macros_on_cmdline): Also allow for command
        line overriding of the `DISABLE_HARD_ERRORS' make variable.  Try
        to avoid false positives for usages like "$MAKE || st=$?".

2011-07-23  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tests: relax a test on amhello examples to cater to Solaris tar
        * tests/amhello-binpkg.test: When the tar implementation in use
        is not GNU tar, relax the tests on tar output, to avoid spurious
        failures.  For example, "tar cvf ..." with GNU tar can output
        lines like "./usr/bin/hello" on the standard output, while with
        Solaris tar it can output lines like "a ./usr/bin/hello 8K" on
        standard output, and with Heirloom tar it can output lines like
        "a ./usr/bin/hello 15 tape blocks" on standard error.

        spurious results).
        * tests/self-check-is_newest: Extend accordingly.

        fails unconditionally: the test must fail only when the 'strict'

2011-08-03  Stefano Lattarini  <stefano.lattarini@gmail.com>

        testsuite: scaffolding to allow use of TAP in our own tests
        Now that Automake has initial support for the TAP test protocol,
        we can start "eating our own dog food" and rewrite some tests to
        use TAP; this should allow for better granularity, especially in
        the control of skips and expected failures.  With this change, we
        set up the initial scaffolding required by the planned TAP tests,
        and convert few older tests to use TAP, mostly in order to verify
        that there are no obvious errors.  The tests in our testsuite that
        use the TAP protocol will be marked by the new `.tap' extension.
        * tests/plain-functions.sh: New file containing definition of
        helper shell functions used by the "protocol-less" tests of the
        Automake testsuite.
        * tests/tap-functions.sh:  New file containing definition of
        helper shell functions used by the TAP-producing tests of the
        Automake testsuite.
        * tests/defs: Remove definitions of some functions that are
        now defined in `plain-functions.sh'.  Instead, source one of
        `plain-functions.sh' or `tap-functions.sh', depending on whether
        `$use_tap' is set to "no" or "yes".
        (exit trap): Call `late_plan_' if `$use_tap' is true.  Also,
        unset shell traces before issuing the latest commands, to avoid
        confusing the tap driver with spurious output.
        * tests/defs-static.in ($use_tap): New variable, by default set
        to "yes" if the calling test script has a `.tap' suffix, and to
        "no" otherwise.  The individual scripts can override it though.
        In code sanity-checking the environment, verify that `$use_tap'
        is not exported.
        * tests/self-check-env-sanitize.test: Update, and small related
        reformatting.
        * tests/self-check-tap.test: New very minimal self test.
        * tests/acoutbs.test, tests/acoutbs2.test, tests/acoutnoq.test,
        tests/acoutpt.test, tests/acoutpt2.test, tests/acoutqnl.test:
        Removed, merged into ...
        * tests/ac-output-old.tap: ... this new test, that uses TAP.
        * tests/Makefile.am (TAP_LOG_DRIVER): Define to invoke our own
        `tap-driver' script.
        (TAP_LOG_DRIVER_FLAGS): Define to `--merge', so that the stdout
        and stderr of the test scripts remains synced.
        (TEST_EXTENSIONS): Define, to add the `.tap' suffix; also list
        the `.test' suffix explicitly.
        (EXTRA_DIST): Distribute the new files `plain-functions.sh' and
        `tap-functions.sh'.
        ($(TEST_LOGS)): Depends on them.
        (AM_TESTS_ENVIRONMENT): Ensure that `use_tap' is not exported in
        the environment of the tests.
        (TESTS): Update.

        testsuite: optimize tests on TAP for speed and against duplication
        The creation and configuration of common files and data used by
        many tests on TAP is, with this change, factored out into a new
        dedicated auxiliary test, from which those tests will depend upon.

        test harness: use new `.trs' files to hold test metadata
        With this change, the test harness will keep test metadata in
        dedicated `.trs' files, instead of having them embedded into the
        `.log' files.  This allows for easier forward-compatibility and
        extension of test metadata, and for more flexibility in the
        format of the `.log' files.  Note that this change makes the
        `:end-metadata:' field obsolete.
        * doc/automake.texi (Parallel Test Harness, Log files generation

        `check2.am', substitute %BASE% with the basename of the `.log'
        file being created by a rule.  Add the generated `.trs' files

        * lib/am/check.am (am__test_driver_flags): Rename ...

        the proper rules in `check2.am'.
        (am__TEST_BASES): New internal variable, holding the names of
        the tests, with any registered extension removed.
        (am__stealth_MAKE): New internal variable, can be used instead of
        $(MAKE) in recipes requiring a recursive call to make, but which
        are not intended to be executed by "make -n".
        (.log.trs): New suffix rule, to recover from deletion of `.trs'
        files.
        ($(TEST_SUITE_LOG)): Almost completely rewritten to follow the
        new API of "test logs in `.log' files, test metadata in `.trs'
        files".  It goes to some length to work correctly in face of
        unreadable or missing `.log' and `.trs' files, and to error out
        with proper error messages when this is not possible.
        [%?PARALLEL_TESTS%] (check-TESTS): Also remove relevant "stale"
        `.trs' files (in addition to `.log files) before remaking the
        $(TEST_SUITE_LOG).
        (recheck, recheck-html): Look for the `:recheck:' field in the

        test harness: allow more metadata in log files
        This change reworks and improves the parallel test harness to use
        more specialized reStructuredText fields in the log files (instead
        of relying on specially-placed of "magic lines" and more indirect
        semantical formatting); the new fields are the following:
         - ":recheck:": tell whether the associated test will have to be
           re-run by "make recheck";
         - ":copy-in-global-log:": tell whether the content of the log
           file should be copied in the "global log" `test-suite.log';
         - ":end-metadata:", which inhibits the scanning of the rest of
           the log file (for what concerns test metadata).
        Also, the special `:test-result:' value "END" has been removed,
        superseded by the new `:end-metadata:' field.
        * doc/automake.texi (Log files generation and test results
        recording): Document the new API and semantics.  Remove or fix
        some obsolete comments.
        * lib/am/check.am ($(TEST_SUITE_LOG), recheck, recheck-html):
        Adjust comments and code.

        (must_recheck, copy_in_global_log): ... these new functions.

        testsuite: fix a spurious failure with non-bash shells
        * tests/tap-fancy2.test: Remove an unportable use of backslashes
        with the `echo' builtin, which was causing some shells (among them
        bash and Debian /bin/ksh) to print a `\\' string, while other
        shells (among them zsh, dash, and Solaris /bin/sh and /bin/ksh)
        were unexpectedly printing a single `\' character.  Since we are
        at it, add a sanity check to ensure that this issue does not
        resurface.

        testsuite: fix spurious failures with Solaris /bin/sh
        * tests/tap-more.test: Use `echo > file', not `: > file', to
        create empty files in the "for" loops; this is required since,
        as documented in the autoconf manual, Solaris 10 /bin/sh
        "optimizes" away the `:' command after the first iteration,
        even if it is redirected.
        * tests/test-driver-custom-multitest-recheck2.test: Likewise.
        * tests/tap-numeric-description.test: Partial rewrite to avoid
        using positional parameters from the 10th onward, which are
        unportable to Solaris /bin/sh (using `${10}' causes the shell
        to die with "bad substitution").

        simple tests: support developer-defined fd redirections
        Motivated by coreutils bug#8846, and related discussions:
         <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=8846>
         <http://lists.gnu.org/archive/html/bug-autoconf/2011-06/msg00002.html>
        In those threads it has been shown how problematic it can be to do
        portable file descriptor redirections in the testsuite when using
        the Automake testsuite harness.  This change should remedy to that
        situation.
        * lib/am/check2.am (?GENERIC?%EXT%$(EXEEXT).log,
        ?GENERIC?%EXT%.log, ?!GENERIC?%OBJ%): Append redirection defined

        couple of still valid checks, to keep the test more in sync with
        the documentation.  Improve debugging information.

        Other related typofixes and rewordings throughout the manual;
        in particular, avoid to use the term "test driver" for three

        parallel-tests: simplify testsuite summary
        Prefer a more deterministic, "tabular" format for the testsuite
        summary, always listing the numbers of passed, failed, xfailed,
        xpassed, skipped and errored tests, even when these numbers are
        zero.  This simplify the logic of testsuite summary creation,
        makes it more easily machine-parseable, and will probably allow
        for easier addition of new kinds of test results in the future.
        * lib/am/check.am (am__tty_colors_dummy): New make variable, to
        reduce code duplication.  Extracted from previous versions of

2011-07-07  Stefano Lattarini  <stefano.lattarini@gmail.com>

        parallel-tests: make parsing of test results safer
        The new code for parsing the testsuite-generated `.log' files,
        as introduced in commit `v1.11-872-gc96b881', considers each
        `:test-result:' field anywhere in a `.log' file as a declaration
        of a test result, and accounts for it as such in the testsuite
        summary.  Unfortunately this could easily cause spurious test
        failures being reported in the testsuite summary.  This happened
        in practice with the Automake's own testsuite; for example:
          $ make check TESTS='check12-p.test'; echo exit: $?
          ...
          PASS: check12-p.test
          =====================================
          4 of 5 tests failed
          See tests/test-suite.log
          Please report to bug-automake@gnu.org
          =====================================
          make[2]: *** [test-suite.log] Error 1
          make: *** [check-am] Error 2
          exit: 2
        This change introduces a new special `:test-result:' "END", that,
        when seen, prevents the rest of the log file from being parsed.
        For more information, refer to the thread:
        <http://lists.gnu.org/archive/html/automake-patches/2011-06/msg00199.html>
        * lib/am/check.am ($(TEST_SUITE_LOG)): Stop the parsing of a log
        file as soon as the special ":test-result:END" directive is seen.

        global log and the console testsuite summary to make it able to
        grasp multiple results per test script.  This is required in order
        to introduce the planned support for test protocols, like TAP and
        SubUnit, which can indeed run multiple tests per test script, each
        with its individual result.
        The implementation makes use of a custom reStructuredText field
        `:test-result:'.
        Note that no new documentation is added by this change; that is
        be left for follow-up changes.
        * lib/check.am ($(TEST_SUITE_LOG)): When processing .log files,
        recognize a report of a test's result only if it is declared with
        the custom `:test-result:' reStructuredText field placed at the
        beginning of a line.  Extend and add explanatory comments.
        (recheck, recheck-html): Add explanatory comments.
        * lib/test-driver: Write an appropriate reStructuredText field
        `:test-result:' in the generated log file.  Use a reStructuredText
        transition to better separate the test outcome report from the
        test script's registered output.  Improve comments.

        parallel-tests: allow custom driver scripts
        Allow suffix-based definition of custom "driver script" for the
        test scripts.  These driver scripts will be responsible of
        launching the tests (or their corresponding $(LOG_COMPILER), if
        they have an associated one), interpreting and displaying the
        test results, and writing the `.log' files.
        This new API should allow easy and flexible use of different
        test protocols in the future; in particular, we plan to use it
        to implement TAP and SubUnit harnesses.
        Note that no new documentation is added by this change; that is
        be left for follow-up changes.
        * automake.in (handle_tests): Define default for $(LOG_DRIVER),

        for $(<ext>_LOG_DRIVER).  Substitute %DRIVER% using these new
        variables, instead of the old internal $(am__test_driver).  When
        processing check2.am, also substitute %DRIVER_FLAGS%.
        Require auxiliary script `test-driver' only if no driver has been
        explicitly defined for the test script kinds.
        * am/check2.am (?GENERIC?%EXT%$(EXEEXT).log, ?GENERIC?%EXT%.log,
        ?!GENERIC?%OBJ%): Pass the %DRIVER_FLAGS% to the %DRIVER% call.

        parallel-tests: add auxiliary script 'test-driver', refactor
        This refactoring should cause no API of functionality change,
        and is meant only to simplify the future implementation of TAP
        and SubUnit testsuite drivers.  More precisely, our roadmap is
        to move most of the "testsuite driving" features out of the
        Automake-generated Makefiles, and into external scripts with
        well-defined interfaces.  This will allow the user to define
        its own personalized testsuite drivers, and will also offer us
        a framework upon which to implement our new TAP and SubUnit
        drivers, all in a very unobtrusive way and retaining an high
        degree of code reuse and backward-compatibility.
        * lib/test-driver: New auxiliary script.
        * lib/Makefile.am (dist_SCRIPT_DATA): Add it.
        * automake.in (handle_tests): Require the new auxiliary script
        `test-driver', and define a new internal makefile variable
        `$(am__test_driver)', used to call it.  Perform new substitution
        on `DRIVER' when processing the `check2.am' file.
        * lib/check.am (am__tty_colors): Define new shell variable
        `$am__color_tests'.
        (am__rst_section): Removed, its role taken over by the new
        `test-driver' script.
        (am__test_driver_flags): New variable, contains the command
        line options passed to `test-driver'.
        (am__check_pre): Do not deal with temporary files and exit
        traps anymore, as the `test-driver' script takes care of that
        now.  Define shell variable `$am__enable_hard_errors', used by
        `$(am__test_driver_flags)'.  Reorder so that we don't need to
        save and restore the value of the `TERM' environment variable
        anymore.
        Other related adjustments.
        (am__check_post): Remove, as its role has been completely taken
        over by the `test-driver' script.
        * am/check2.am (?GENERIC?%EXT%$(EXEEXT).log, ?GENERIC?%EXT%.log,
        ?!GENERIC?%OBJ%): Call the test script through the Automake
        substituted `%DRIVER%', and honor the command-line options
        in `$(am__test_driver_flags)'.  Do not call the obsoleted
        `$(am__check_post)' anymore.
        * doc/automake.texi (Auxiliary Programs): Mention the new
        `test-driver' script.
        (Optional): Mention `test-driver' in AC_CONFIG_AUX_DIR.
        Since we are at it, break the list of auxiliary scripts by
        placing one per line, to simplify potential future additions
        of new scripts.

        test defs: fix ksh-related portability bug in warning messages
        Running "make check" normally prints a diagnostic to the outermost
        stderr (usually a tty) to explain why a test is skipped, thus
        giving better and faster feedback to the user.  It used to do
        so by redirecting file descriptor 9 to stderr (via "exec 9>&2")
        before invoking the test scripts, which then would write any skip
        explanation to file descriptor 9 via the `skip_' function defined
        in `tests/defs'.
        However, various Korn Shells (at least Solaris 10's /bin/ksh and
        Debian GNU/Linux's /bin/ksh) and the HP-UX's /bin/sh close open
        file descriptors > 2 upon an `exec' system call; thus the effects
        of "exec 9>&2" are cancelled upon fork-and-exec, so we would get
        a "Bad file number" diagnostic and no skip explanation with those
        shells.
        The present change remedies this situation.
        * tests/Makefile.am (AM_TESTS_ENVIRONMENT): Redirect more portably,
        via a trailing "9>&2", rather than the prior "exec 9>&2; ...".  Add
        explanatory comments.
        * tests/defs (stderr_fileno_): Update the advice in comments.
        Based on commit v8.12-82-g6b68745 "tests: accommodate HP-UX and

        Since commit `v1.11-910-g7df1a9b', the once user-overridable
        variable `$test_prefer_config_shell' has become an internal
        detail, and the test scripts now complain and bail out if it is
        set in the environment.
        * tests/Makefile.am (AM_TESTS_ENVIRONMENT): Unset the variable
        `test_prefer_config_shell' if it is set in the environment.

2011-06-13  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tests: autogenerate list of wrapped tests for `lib/' shell scripts
        * tests/gen-config-shell-tests: New script, generates distributed
        makefile snippet `tests/config-shell-tests.am' to list all tests
        that use the `get_shell_script' function, with names mangled to
        use suffix `-w.shtst', in ...
        * tests/Makefile.am (config_shell_tests): ... this macro, whose
        definition has been consequently removed from Makefile.am.
        (EXTRA_DIST): Distribute the new script.
        ($(srcdir)/config-shell-tests.am): Generate using the new script.
        (include): Include the `config-shell-tests.am' fragment.
        * bootstrap: Invoke `tests/gen-config-shell-tests' to generate
        `tests/config-shell-tests.am'.
        * tests/.gitignore: Ignore `config-shell-tests.am'.
        * tests/gen-parallel-tests: Fixlet in heading comments.

2011-06-13  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tests: test mdate-sh with /bin/sh too
        * tests/mdate5.test: Fetch the `mdate-sh' script using the
        `get_shell_script' function, and run it directly instead of
        using `$SHELL'.
        * tests/mdate6.test: Likewise.  Since we are at it, make checks
        on the `mdate-sh' output stricter, remove now unneeded calls to
        aclocal and automake and creation/extension of `configure.in',
        `Makefile.am' and `textutils.tex' files, and add a trailing `:'
        command.
        * tests/Makefile.am (config_shell_tests): Add `mdate5-w.shtst'
        and `mdate6-w.shtst'.

2011-06-13  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tests: extend tests on `--add-missing' and `--copy' a bit
        * tests/add-missing.test: Fix typo in heading comments.  Try with
        another testcase that install many (but not all) the auxiliary
        scripts at once, and uses non-standard (but valid and documented)
        setups (e.g., defining YACC in Makefile.am instead of calling
        AC_PROG_YACC from configure.in).
        * tests/copy.test: Reference `add-missing.test' in heading
        comments.  Try few more test scenarios.

2011-06-16  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tests: few fixlets and improvements
        * tests/cond31.test ($required): Remove `cc', it's not really
        needed.
        * tests/confh.test: Call autoheader too.  The lack of this call
        wasn't causing spurious failures because the automatic remake
        rules were somehow invoking it on our behalf (at make time).
        * tests/fn99subdir.test: Use $subdirname throughout, instead of
        ${subdirname}, for consistency with the rest of the testsuite.
        Avoid an unnecessary subshell, which could also cause spurious
        passes, being guarded by a trailing `|| Exit 1', which neutralize
        the `errexit' flag.  Remove an unnecessary `|| Exit 1' guard.
        * tests/insh2.test: Rewrite to avoid hackish Makefile.in munging,
        and to also run configure and make.

2011-06-13  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tests: don't hard-code test name in txinfo21.test
        * tests/txinfo21.test: Use `$me' instead of hard-coding the
        current testcase name "txinfo21".  Add a trailing `:' command
        since we are at it.

2011-06-10  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tests: new test dedicated to `--add-missing' and `--copy'
        * tests/add-missing.test: New test.
        * tests/Makefile.am (TESTS): Update.
        Suggested by Peter Rosin.

2011-06-08  Stefano Lattarini  <stefano.lattarini@gmail.com>

        testsuite: use 'fatal_' and 'framework_failure_' for hard errors
        * tests/defs (require_xsi): Use `fatal_', not `framework_failure',
        to report an invalid usage.
        * tests/remake-gnulib-remove-header.test: Prefer using `fatal_'
        with a proper error message over a direct call to `Exit 99'.
        * tests/pr8365-remake-timing.test: Likewise.
        * tests/cygnus-imply-foreign.test: Likewise.

        * tests/cond33.test: Likewise.
        * tests/python-virtualenv.test: Prefer using `framework_failure_'
        with a proper error message over a direct call to `Exit 99'.
        * tests/instspc-tests.sh: Prefer using `framework_failure_' and
        `fatal_' over direct calls to `Exit 99'.
        (fatal_): Define this (which is a simplified version of the one
        in `tests/defs') for early uses (i.e., before `tests/defs'
        gets sourced).
        * tests/depmode-tests.sh: Likewise.  Also, simplify the
        'get_depmodes' function and calls to it accordingly.

2011-06-08  Stefano Lattarini  <stefano.lattarini@gmail.com>

        self tests: check new 'fatal_' function
        * tests/self-check-exit.test: Also check the new 'fatal_'
        function.

2011-06-08  Stefano Lattarini  <stefano.lattarini@gmail.com>

        test defs: new function 'fatal_', for hard errors
        Before this patch, the only way offered by tests/defs to
        properly signal a hard error was the `framework_failure_'
        function.  But the error message issued by that function,
        as its name would suggest, refers to a set-up failure in the
        testsuite, while hard errors can obviously also be due to
        other reasons.  The best way to fix this inconsistency is to
        introduce a new function with a more general error message.
        Inspired by a recent similar change to Gnulib's tests/init.sh.
        * tests/defs (fatal_): New function.
        * tests/README (Section "Writing test cases" subsection "Do"):
        Suggest the use of `fatal_', not of `framework_failure_', for
        generic hard errors.  The latter should be reserved for "real"
        set-up failures.

        py-compile: '--' and non-option arguments terminate the option list
        * lib/py-compile: Any non-option argument, or the special `--'
        argument, now explicitly terminates the list of options.
        * tests/py-compile-option-terminate.test: New test.
        * tests/Makefile.am (TESTS): Update.

        * tests/py-compile-usage.test: Extend accordingly.
        * NEWS: Update.

2011-06-08  Stefano Lattarini  <stefano.lattarini@gmail.com>

        py-compile: normalize error and help messages
        * lib/py-compile: Now error messages do not begin with a capital
        letter, nor end with a period, as per GNU standards.  Prepend the
        error messages with the name of the script, not with its path.
        When an invalid usage is recognized, always display the customary
        message "Try `py-compile --help' ..." on a line of its own.
        ($me): New variable, containing the name of the
        program, i.e., `py-compile'.  Use it throughout.
        (usage_error): New function, used to display error messages about
        invalid usage.
        * tests/py-compile-usage.test: Extend and tighten accordingly.

2011-06-08  Stefano Lattarini  <stefano.lattarini@gmail.com>

        py-compile: the '--destdir' option now accepts a blank argument
        * lib/py-compile (Option parsing): Do not count an empty argument
        to `--destdir' or `--basedir' as a missing argument.
        * lib/python.am: Simplify accordingly, passing the `--destdir'
        option to py-compile unconditionally, even if `$(DESTDIR)' is
        empty.
        * NEWS: Update.

2011-06-08  Stefano Lattarini  <stefano.lattarini@gmail.com>

        python: run the 'py-compile' script with $(SHELL)
        * lib/python.am (install-%DIR%PYTHON): Run each instance of
        py-compile using $(SHELL).  Since we are at it, break overly
        long lines.
        (am__py_compile): New variable, to reduce code duplication.


2011-06-07  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tests: `lib/' shell scripts transparently tested also with $SHELL
        With the previous commit, the user could prefer the use of $SHELL
        over /bin/sh in some tests checking the Automake-provided shell
        scripts by manually exporting `test_prefer_config_shell' to "yes"
        in the environment.  With this commit, we ensure that such tests
        *always* and *transparently* run using both $SHELL and /bin/sh
        to execute the checked scripts.  The `test_prefer_config_shell'
        variable becomes an internal detail, and is no more meant to be
        manually defined or overridden.
        * tests/defs-static.in: Check that `test_prefer_config_shell' is
        not exported in the environment.  Error out if this is the case.
        * tests/config-shell-tests.sh: New file, driver script to run
        checks on the shell scripts in `lib/' using the $SHELL determined
        at configure time instead of the default system shell /bin/sh.
        * Makefile.am (TESTS_EXTENSIONS): Add `.shtst'.
        (SHTST_LOG_COMPILER): Define, it calls `config-shell-tests.sh'.
        (config_shell_tests): Define to a list of tests that wraps other
        `*.test' tests using `config-shell-tests.sh'.
        ($(config_shell_tests)): Dummy dependency declaration required
        in order to have make actually produce expected log files from
        the `.shtst.log' suffix rule.
        (EXTRA_DIST): Distribute `config-shell-tests.sh'.
        (TESTS): Add `$(config_shell_tests)'.
        * tests/self-check-env-sanitize.test: Update, by checking that
        `test_prefer_config_shell' isn't exported in the environment.

2011-06-07  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tests: can use also $SHELL to check shell scripts from `lib/'
        * tests/ar-lib.test: If the variable `$test_prefer_config_shell'
        is set to "yes", run the script under test with configure-time
        determined $SHELL, rather than with /bin/sh.
        The `$test_prefer_config_shell' variable defaults to empty, but
        can be overridden at runtime by the user, thus allowing more
        coverage.

        (xsi-lib-shell): If `$test_prefer_config_shell' is set to "yes",
        check that $SHELL, not /bin/sh, supports XSI constructs, as we
        expect the test will use $SHELL and not /bin/sh to run the
        script being tested.

2011-06-07  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tests defs: better requirements for XSI shells
        This change avoids potential spurious failures with tests using
        the requirement 'xsi-shell' to mean that they want */bin/sh* (not
        $SHELL) to be XSI-conforming.  This idiom used to work before
        commit `v1.11-874-g1321be7' (as back then the test scripts were
        unconditionally run with /bin/sh), but has become inconsistent
        now that the test scripts re-execute themselves with configure
        determined $SHELL.
        The described spurious failures have already occurred in practice,
        for examples on Solaris systems which also had GNU Bash installed.
        From a suggestion by Peter Rosin.  See discussion at:
        <http://lists.gnu.org/archive/html/automake-patches/2011-06/msg00016.html>
        * tests/defs (xsi-shell): Now check that $SHELL, rather than the
        shell currently running the test script, is an XSI shell.
        (xsi-bin-sh): New requirement, checking that /bin/sh (which can
        differ from $SHELL) is an XSI shell.
        (xsi-lib-shell): New requirement, checking that the shell that
        should be used to test the Automake-provided scripts from `lib/'
        is an XSI shell.  For the moment, this is just an alias for
        `xsi-bin-sh'.
        (require_xsi): New subroutine, used to factor out code common to
        the requirements above.
        ($xsi_shell_code): New variable, contains shell code supposed to
        work only with XSI shells.  Used by the new subroutine above.
        * tests/ar-lib.test ($required): Require 'xsi-lib-shell' instead
        of 'xsi-shell', since the script we test here is run with /bin/sh,
        not with $SHELL.
        * tests/compile3.test: Likewise.
        * tests/compile6.test: Likewise.

        tests: fix typo-related error in auxdir2.test
        * tests/auxdir2.test (configure.in):  Close m4 quoting in the
        argument to AC_CONFIG_AUX_DIR.  Without this, aclocal fails with
        "ERROR: end of file in string".  This problem hasn't been exposed
        by the testsuite before because this test is in XFAIL_TESTS, so
        its failure went unnoticed, even if it was due to a wrong cause.
        Bug introduced in commit v1.11-249-g49ac3de.

        self tests: check that `$me' can be overridden
        * tests/self-check-me.test: Check that `$me' can be overridden
        before sourcing ./defs, with or without sourcing ./defs-static
        beforehand, and that this override is honored.  Update heading
        comments.

2011-06-02  Stefano Lattarini  <stefano.lattarini@gmail.com>

        self tests: fix another spurious failure
        Our ad-hoc usage of `tests/defs' in the testsuite's self tests
        stopped working properly when we made the test scripts re-execute
        themselves with the configure-time $SHELL.  Fix this.
        Fixes a regression introduced by commit 'v1.11-874-g1321be7'.
        * tests/self-check-exit.test: Export `AM_TESTS_REEXEC' to "no"
        before running the self tests.  This fixes a spurious failure
        present only when the test was run by hand.

        silent-rules tests: fix spurious failures with Sun Studio C++
        * tests/silentcxx.test: The C++ compiler from Sun Studio is named
        `CC'.  Account for this in our grepping checks on the make output.
        Since we are at it, throw in a couple of improvements to comments
        and formatting.
        * tests/silent-many-generic.test: The C++ compiler from Sun Studio
        is named `CC', and this can cause spurious failures in our grepping
        of the make output.  Work around this by using a wrapper script
        around the C++ compiler (generated on the fly), since filtering the
        make output proved to be too fragile.

        tests: fix spurious failure in backcompat2.test on NetBSD
        * tests/backcompat2.test: Add trailing `:' in the body of a `for'

        different 0.  This work around `set -e' issues in some BSD shells,
        e.g., NetBSD /bin/ksh.

        (sc_diff_aclocal_in_aclocal): New maintainer check, similar to
        the above, and checking that only 10 lines are changed from
        `aclocal.in' to `aclocal'.
        (syntax_check_rules): Update.
        (sc_tests_Exit_not_exit): Exempt self tests `self-check-*.test'
        from this check, as they can legitimately use the bare `exit'
        builtin in various places.
        * doc/automake.texi (Python): Remove stray `@' from the end of
        a line.  Typo introduced in commit `v1.11-312-g5bf7af6'.
        * tests/depcomp8a.test: Pass DISTCHECK_CONFIGURE_FLAGS to make

        remake: behave better with non-GNU make in subdirectories
        Currently, with every decent make program, it is possible to
        rebuild out-of-date autotools-generated files with a simple
        "make Makefile" -- but for this to work reliably with non-GNU
        make implementations, the command must be issued from the
        top-level directory.  This patch removes such limitation.

        tests: prefer ulimit over timeout in test on a memory-hogging bug
        * tests/cond29.test: Use 'ulimit' instead of 'timeout' to ensure
        that automake does not uses up too much resources.  This is really
        and improvement because the bug tested by this script wasn't just
        a "it hangs" or "it runs too slow" bug, but rather a memory-hogging
        bug (due to combinatorial explosion when many Automake conditionals
        had to be handled) which could easily crash the whole system, which
        is unacceptable.  The requirement of a proper and working 'ulimit'
        builtin might cause the test to be skipped on more systems, but
        that shouldn't be a problem since the bug isn't about a portability
        issue, but is rather an automake internal implementation problem.
        I've verified that the test as updated by this patch still passes
        with automake 1.8.5, automake 1.10.2, and obviously the development
        version of automake, and that it fails with automake 1.7.9.

        testsuite: avoid generating `*-p.test' tests, use a wrapper script
        The generated `*-p.test' tests had already become just thin layers
        around the corresponding test scripts.  This change makes the final
        step, converting to the use of a generic wrapper script and thus
        avoiding the extra test generation (similarly to what is done for
        the `*.instspc' and `*.depmod' tests).
        * tests/parallel-tests.sh: New file, driver script to run checks
        the on the `parallel-tests' semantics by wrapping tests that use

        `.ptest' extensions used for tests in $(parallel_tests).

        (PTEST_LOG_COMPILER): Define, it calls `parallel-tests.sh'.
        ($(parallel_tests)): Do not really generate `*-p.test' tests
        anymore; this is now just a dummy dependency declaration required
        in order to have make actually produce expected log files from
        the `.ptest.log' suffix rule.

        automake, aclocal: honour configure-time AUTOCONF and AUTOM4TE
        Currently, the Automake's own configure script allow definition
        of AUTOCONF and AUTOM4TE, expected to point respectively to an
        autoconf and autom4te programs.  But while these definitions are
        honoured in the Automake's build systems and test suite, they
        were *not* honoured in the generated `automake' and `aclocal'
        scripts.  This behaviour, apart from being wrong in that it does
        not allow the user enough freedom in choosing his tools, also
        caused inconsistencies in the test suite, brining to spurious
        failures.
        Problem reported by Graham Reitz on the automake list; see thread:

        build: the user can override AUTOM4TE, AUTORECONF and AUTOUPDATE too
        Our build system allows the user to override AUTOCONF and AUTOHEADER
        at configure time, and honours these overrides in our testsuite.
        But it didn't do the same with AUTOM4TE, AUTORECONF and AUTOUPDATE.
        This change fixes that inconsistency.

        tests/README: fix example about `make -e' usage
        * tests/README (Section "Writing test cases" subsection "Do"): When
        some variable is never initialized in the Makefile, `-e' is not
        necessary in order to override it.  DESTDIR is such a variable: we
        ensure that we do not ever initialize it.  And as such, it is quite
        portable to use:
          $ make DESTDIR=/foo/bar install
        and in fact, quite widely used.
        So our example about when `make -e' is required, which references
        the `DESTDIR' variable, is poorly chosen, if not downright wrong.
        Rewrite it to use `prefix' as the overridden variable instead.

        tests: tweak and improve tests on Automake conditionals
        The "avoid the requirement of a working compiler" we refer about

        dummy values, either directly in the `Makefile.am', or by AC_SUBST
        in `configure.in'.
        The "cosmetic changes" we refer about below consists in, e.g.,
        adding a trailing `:' command to a script, using proper m4 quoting
        in `configure.in' files, adding commands that offer more debugging
        output, explicitly declaring phony targets as such in Makefiles,
        making use of idioms more consistent with those employed in other

        of just hoping that the user will notice an abnormally long test
        execution time.

        lex tests: avoid spurious failures when LEXLIB isn't found
        The AC_PROG_LEX Autoconf macro does not diagnose a failure to find
        the "lex library" expected to provide a `yywrap' function (function
        which is required to link most lex-generated programs).  On the
        contrary, when all the link attempts (i.e., with `-ll' and `-lfl')
        fail, configure declares that no lex library is needed, and simply
        proceeds with the configuration process -- only for the build to
        possibly fail later, at make time.
        This behaviour might be (partly) intended; the Autoconf manual
        reads:
         ``You are encouraged to use Flex in your sources, since it is
           both more pleasant to use than plain Lex and the C source
           it produces is portable.  In order to ensure portability,
           however, you must either provide a function `yywrap' or, if
           you don't use it (e.g., your scanner has no `#include'-like
           feature), simply include a `%noyywrap' statement in the
           scanner's source.''
        This AC_PROG_LEX behaviour is causing some spurious failures of the
        Automake testsuite in environments which lack a proper library
        providing `yywrap' (this happens for example in Linux->MinGW cross
        compilations).  But at this point is clear that a proper workaround
        is to simply provide a fall-back implementation of `yywrap' in our
        lexers.
        * tests/cond35.test: Provide a dummy `yywrap' function.

        testsuite: allow user to ask for stricter skip semantics
        Given how the Automake testsuite is currently structured, if a
        command in a test script fails with status `77', the global test
        outcome is considered a SKIP, because the value of `77' for `$?'
        is passed to the exit trap.  Indeed, this happens in practice, as
        an autoconf-generated configure script can exit with status `77'
        if it fails to find, e.g., a required compiler.
        While this behaviour is quite useful for avoiding spurious test
        failures in the wild, it can also sometimes prevent the Automake
        developers to easily see and declare the requirements of their
        tests.
        This change introduces a new variable `am_explicit_skips', meant to
        be user-overridable, and which, when set to a "true" value (i.e.,
        `yes' or `1'), require a direct call to `Exit 77' in order to make
        the test outcome be considered a SKIP.
        * tests/defs.in ($am__test_skipped): New variable, initialized
        to `no'.
        (Exit): Set `$am__test_skipped' to `yes' if passed an exit status
        of 77.
        (trap '...' 0): When `$am_explicit_skips' is set to a "true" value,
        reset an exit status of `77' to `78' if $am__test_skipped is not
        set to `yes'.
        * tests/self-check-exit.test: Adjust: unset `am_explicit_skips'.
        * tests/self-check-explicit-skips.test: New test.
        * tests/Makefile.am (TESTS): Update.

2011-05-24  Stefano Lattarini  <stefano.lattarini@gmail.com>

        testsuite: user can force skipping of compiler-requiring tests
        * tests/defs (cc, c++, fortran, fortran77): Skip the test if
        the relevant compiler is disabled by having the corresponding
        variable (CC, CXX, FC and F77, respectively) set to "false".
        (yacc): For consistency, skip the test when the YACC variable
        is set to "false", not when it's set to "no".  Since we are at
        it, fix the skip message to be shorter and more consistent.

        with GNU Coding Standards.
        * tests/parallel-tests3.test: Use a shorter and clearer skip
        message.  Use the `unindent' subroutine to improve readability
        of indented loop bodies.  Simplify the hack used to please
        maintainer-check.
        * tests/parallel-tests5.test: Make formatting of created *.c
        files more consistent with GNU Coding Standards.  Use the
        `unindent' subroutine to improve readability of indented loop
        bodies.
        * tests/parallel-tests10.test: Add blank line, for clarity.
        Prefer trailing `:' over trailing `Exit 0', for consistency
        with other tests.

        * tests/defs-static.in ($host_alias, $build_alias): New variables,
        exported, user-overridable, defaults AC_SUBST'd by configure.
        * tests/defs (cross_compiling): Consider cross-compilation mode
        active only if `$host_alias' is not empty *and* it differs from
        `$build_alias'.  This is more faithful to the way configure
        determines whether it is cross-compiling, but still allows the
        user to easily force cross-compilation by overriding `host_alias'
        and `build_alias' at runtime.

2011-05-20  Stefano Lattarini  <stefano.lattarini@gmail.com>

        testsuite: avoid re-running few tests with 'parallel-tests' option
        Some tests in our testsuite use the 'simple-tests' driver only
        marginally, or simply as a mean to conveniently check unrelated
        invariants.  It makes little sense to force these tests to also
        run with the 'parallel-tests' Automake option active, as doing so
        offers no real gain in coverage, while often causing a measurable
        overhead in execution time (for an already too-slow testsuite).
        * tests/pr401.test (parallel_tests): Define to "no", to prevent
        the generation of a sibling test script using the 'parallel-tests'
        driver.

        to any other value.  Extend heading comments to give a rationale
        for this behaviour.

        tests/README: update obsoleted advice
        * tests/README (Section "Writing test cases" subsection "Do"):
        Do not suggest to use the `*-p.test' pattern for the names of
        hand-written tests which use the `parallel-tests' Automake option.
        Not only is this not respected by the existing tests, but it is
        more likely to cause conflicts with auto-generated tests.
        So, suggest to *avoid* using the `*-p.test' pattern in names
        of hand-written tests instead.
        (Section "Writing test cases" subsection "Do not"):  When
        suggesting not to override Makefile variables using command
        line arguments, do not use the badly outdated variables `U'
        and 'ANSI2KNR' in the example; instead, use the more common
        and typical `DESTDIR'.

        * tests/extradep.test: When using `ls -t' to determine whether a
        file has been updated, make sure to use as reference a file whose
        timestamp is expected to be *strictly* older that that of the file
        being checked.  This is required because at least FreeBSD `ls' do

        wrong since it gets run before `./defs' is sourced, and thus `$nl'

        lex: "make clean" removes .c files from non-distributed .l
        Previously, while automake did *not* distribute C source and header
        files derived from non-distributed Lex sources, it still caused
        them to be removed only by "make maintainer-clean" only, and not by
        simply "make clean" or "make distclean".
        This caused "make distcheck" to fail, unless the developer put
        those generated .c files in CLEANFILES or in DISTCLEANFILES by
        hand.
        This change fixes this issue, by making non-distributed `.c' files
        generated by non-distributed Lex sources cleaned by "make clean".
        A similar problem for Yacc support had been fixed with the commit
        v1.11-263-ged2c8bc.
        * tests/automake.in (lang_lex_target_hook): Make C source files
        derived from non-distributed Lex files cleaned by "make clean",
        not only by "make maintainer-clean".
        * tests/lex-clean.test: New test.

        lex tests: remove erroneous check about ylwrap distribution
        * tests/lex5.test: Do not check that the ylwrap script is *not*
        distributed when there is only one lexer, as ylwrap is in fact
        expected to distributed unconditionally (at least starting from
        commit `Release-1-9-323-gc5881cc' of 19-08-2006).  Note that this
        bogus check wasn't triggering any failure because it was done at
        the wrong time (i.e. from the VPATH build directory), so that it
        could never fail anyway.
        Instead, check that ylwrap is distributed even when there is only
        one lexer.
        Since we are at it, add a couple of `ls -l' calls, to get better
        debugging info.

2011-05-04  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tests defs: allow requirements for compilers (mostly dummy)
        Most of the new requirements that are now accepted in `$required'
        as consequence of this patch are still dummy.  They are planned
        to be implemented only in master (or in some derived branch), but
        having them here (even just as no-op) will allow for an easier
        integration/backporting of potential new testcases.
        * tests/defs.in (cc, c++, fortran, fortran77): New requirements,
        still dummy.
        (flex): New requirement, picking LEX for configure.
        (lex): New requirement, alias for `flex'.  A more appropriate
        implementation, looking for a generic `lex' program, will follow
        in the future.

2011-05-04  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tests: 'silent-many-gcc.test' improved and made more robust
        * tests/silent-many-gcc.test:  Also force "fast" gcc depmode

        cache variables we force are really used by configure.  Fix
        typo in comments.

        tests: drop useless requirements of 'g++'
        * tests/lflags2.test ($required): Remove 'g++', as any working

        test to skip if no working C++ compiler is found.
        * tests/yflags2.test: Likewise.

        tests defs: one more environment sanitization (corner case)
        * tests/defs (am__using_gmake): Initialize.  The `using_gmake'
        subroutine was using this variable for caching, but wasn't

        newly generated `*.depmod' tests.
        (TESTS_EXTENSIONS): Add `.depmod'.
        (DEPMOD_LOG_COMPILER): Define.  It calls `depmod-tests.sh', so that
        the "depmode tests" will be executed by passing that driver script
        a proper parameter.
        ($(depmod_tests)): New dependency declaration (dummy, but required
        in order to have make actually produce expected log files from the
        `.depmod.log' suffix rule).
        (TESTS): Add $(depmod_tests).
        (EXTRA_DIST): Distribute depmod-tests.sh.
        Other minor cosmetic changes and reorderings.
        * bootstrap: Generate depmod-tests.am.

        We don't really need to generate tons and tons of wrapper test
        scripts (presently, ~ 90) just to run what is basically a single
        test (specifically, `instspc-tests.sh') with different parameters.
        In fact, the possibility of running a single driver script with
        multiple files/configurations/parameters is one of the major
        selling points of the 'parallel-tests' testsuite driver of
        automake.  So why not use ourselves more extensively the best
        features we provide?
        * tests/instspc-tests.sh: Update heading comments.  Expect
        to be executed, not sourced.  Update handling of command-line
        arguments.  Adjust to reflect the renaming of "instspc tests"
        from `instspc-*.test' to `*.instspc'.
        * tests/instspc-data.test: Update heading comments.  Execute
        driver script `instspc-tests.sh', instead of sourcing it.
        Give more informative messages in case of internal errors.
        * tests/Makefile.am (TESTS_EXTENSIONS): Define explicitly (to
        `.test' and `.instspc').
        (TESTS): Add `$(instspc_tests)'.
        (generated_tests): Remove `$(instspc_tests)'.
        (INSTSPC_LOG_COMPILER): Define.  Calls `instspc-tests.sh', so
        that the "instspc tests" will be now executed by passing that
        driver script a proper parameter.
        ($(instspc_tests)): Remove, we don't need anymore to generate
        this tests.
        ($(instspc_tests:.test=.log)): Remove, substituted by ...
        ($(instspc_tests:.instspc=.log)): ... this.
        ($(instspc_tests)): New dependency declaration (dummy, but
        required in order to have make actually produce expected log
        files from the `.instspc.log' suffix rule).
        (MAINTAINERCLEANFILES, generated_tests): Don't extend with
        $(instspc_tests) anymore.
        Update comments.

        build: improve the definition of the list of testcases
        * tests/Makefile.am (handwritten_tests): New variable.
        (generated_tests): Likewise.
        (TESTS): Redefine as the union of the above.
        (EXTRA_DIST): Extend using $(handwritten_tests) and
        $(generated_tests) rather than $(TESTS).
        * tests/gen-parallel-tests: Update accordingly, and
        make more robust.

2011-05-01  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tests skips: shorter and clearer messages
        * tests/defs: Use shorter messages when giving reasons for test
        skipping; it turns out these shorter messages are also clearer.
        If more info might be useful, send them to the log file only.

        tests: fix self check spurious failure with older bash versions
        * tests/self-check-cleanup.test: Add trailing `:' to the test code
        passed to $SHELL, otherwise older versions of bash (at least 2.05
        and 3.2.39) fail to correctly remove the temporary directory in
        the exit trap.

2011-05-01  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tests: add sanity check to 'self-check-cleanup.test'
        * tests/self-check-cleanup.test: Check that the "hacked" file
        `defs-static' used by the test differs from the "vanilla" one
        in builddir.  This also offers a little more debugging output.

2011-05-01  Stefano Lattarini  <stefano.lattarini@gmail.com>

        testsuite: display reasons for skips to the console
        * tests/Makefile.am (AM_TESTS_ENVIRONMENT): Open file descriptor
        `9' to the original stderr; define `stderr_fileno_' to `9', and
        export it.
        * tests/self-check-report.test: Prevent new spurious failures by
        removing from the environment any definition of `stderr_fileno_'.

        testsuite: use `skip_' for skipping of tests
        * tests/defs: Use the `skip_' subroutine for test skipping.  Also

        * tests/defs-static.in: ... in here, with some optimizations to
        avoid useless forks.  Also, do the same checks for the variables
        `original_AUTOMAKE' and `original_ACLOCAL' too.
        * tests/self-check-env-sanitize.test: Update.
        * tests/Makefile.am (TESTS_ENVIRONMENT): Unset also variables
        `original_AUTOMAKE' and `original_ACLOCAL'.

        * tests/parallel-tests-reset-term.test: Use AM_TESTS_ENVIRONMENT

        not present in the displayed test name, since the simple-tests
        driver do not try to strip them.

        * tests/Makefile.am (TESTS): Update.

2011-05-03  Stefano Lattarini  <stefano.lattarini@gmail.com>

2011-04-18  Stefano Lattarini  <stefano.lattarini@gmail.com>

        check: rename AM_TESTS_SETUP -> AM_TESTS_ENVIRONMENT
        The AM_TESTS_SETUP naming was not a good one after all.  It may
        be technically more correct than AM_TESTS_ENVIRONMENT, but the
        latter is a better one simply because it is easier to remember,
        and even if you've never heard of it and only know the semantics
        of TESTS_ENVIRONMENT, you can have a straightforward way to
        figure out how AM_TESTS_ENVIRONMENT would work.
        * tests/check.am (am__check_pre): Update.
        * doc/automake.in (Simple Tests using parallel-tests): Update.
        * tests/parallel-tests-am_tests_setup.test: Renamed ...

        * tests/Makefile.am (TESTS): Update.

        yacc: extension of headers modelled after extension of sources
        With this change, if '-d' is in *YFLAGS, a yacc input file named
        foo.y++ will cause a foo.h++ header to be generated, instead of a
        foo.h header.  Similarly for foo.ypp, foo.yxx and foo.yy.
        This way, the name of the files generated by an automake-created
        `ylwrap' invocation should be consistent with those generated by
        a `bison -o' call.
        Related to automake bug#7648 and PR automake/491.

        tests: don't define YACC and LEX in the Makefiles
        We don't want YACC and LEX defined as make variables, otherwise
        the values determined at configure time will override those from
        the environment, even in the make-spawned testcases.  For example,
        before this change, with the following usage:
          $ ./configure YACC=yacc
          $ export YACC='bison -y'
          $ make check
        the testsuite would have ended up, very counterintuitively, with
        YACC defined to 'yacc' in the testcases' environment.

        of automake error messages stricter.  Do not redirect output of
        grep to /dev/null.  Move call to aclocal earlier.  Reduce the
        number of empty blank lines.  Fix a typo in comments.
        * tests/yacc8.test: Fixed bugs that reduced the completeness of
        the tests.  Added trailing `:' command.
        (configure.in): Use pre-populated skeleton set up by ./defs,
        instead of writing one from scratch.
        * tests/yaccpp.test: Test also extensions `.y++', `.ypp', and
        `.yxx', rather than only `.yy'.
        * tests/Makefile.am (TESTS): Update.

        yacc: "make clean" removes .c and .h files from non-distributed .y
        Previously, while automake did *not* distribute C source and header
        files derived from non-distributed Yacc sources, it still caused
        them to be removed only by "make maintainer-clean" only, and not by
        simply "make clean" or "make distclean".
        This caused "make distcheck" to fail, unless the developer put
        those generated .c and .h files in CLEANFILES or in DISTCLEANFILES
        by hand.
        This change fixes this issue, by making non-distributed `.c' and
        `.h' files generated by non-distributed Yacc sources cleaned by
        "make clean".
        * tests/automake.in (lang_yacc_target_hook): Make C source and
        header files derived from non-distributed Yacc files cleaned by
        "make clean", not only by "make maintainer-clean".

        has left part of an intended comment not prefixed by `#', thus
        causing shell syntax errors.  In this same comment, break a
        too-long reported error message on multiple lines, for clarity.
        Add reference to the relevant bug report.  Add a comment which

        test defs: fix 'javac' requirement for older JDK versions
        The Java compiler from JDK 1.5 (and presumably earlier versions)
        cannot handle the `-version' option by itself; and while it does
        print the version number, it then errors out with an usage error:
          $ javac -version
          javac 1.5.0_22
          javac: no source files
          Usage: javac <options> <source files>

        maintcheck: look for problematic names of testcases
        The configure.in stub created by default by `tests/defs' obtains
        the first argument of AC_INIT from the test name, and this can
        cause some supported autoconf versions to fail with a spurious
        error if that test name contains the name of an m4 or m4sugar
        builtin or macro (e.g., `defn' or `m4_undefine').
        See for example the bug fixed by commit v1.11-287-g1325a8a.
        This change add a maintainer check that warns about test names
        which are possibly problematic in this regard.

        libtool: suggest LT_INIT if LTLIBRARIES primary is used
        When the LTLIBRARIES primary was used, but $(LIBTOOL) wasn't
        defined, automake suggested to add a call to AC_PROG_LIBTOOL
        in configure.ac.  But that macro is deprecated since Libtool
        version 1.9b (2004-08-29), in favor of the newer LT_INIT.  So
        suggest the use of this latter macro instead.
        * lib/Automake/Variable.pm (%_am_macro_for_var): Pair 'LIBTOOL'
        with 'LT_INIT', not with 'AC_PROG_LIBTOOL'.
        * tests/libtool4.test: Adjust and extend.  Also, add a call to

        tests: optimize `instspc-*.test' for speed
        After the split of `instspc.test' into various generated tests,
        the running time of the testsuite has noticeably increased, since
        all of these new generated tests must run aclocal, autoconf and
        automake, whereas previously they were run only once (at the
        beginning of `instspc.test').  But luckily, since the new tests
        share the same input files for the autotools, this situation can
        be easily worked around (at the expenses of a slight increase of
        complexity for the testsuite scaffolding).
        * tests/instspc-data.test: New helper test, properly calling
        the `instspc-tests.sh' script to generate input data for the

        * tests/instspc-tests.sh: Recognize new action `generate-data',
        and use it to create hand-written and autotools-generated static
        files shared by all the `instspc-*.test' tests.
        When sourced by the `instspc-*.test' tests, use those previously
        created files instead of recreating them from scratch.
        (unindent, create_input_data): New subroutines.
        Some other related changes and refactorings.
        From a suggestion by Ralf Wildenhues.

        python: fix spurious failure in tests
        * tests/python-vars.test: Ignore cached values from config.site
        by exporting CONFIG_SITE=/dev/null.  Be laxer in matching the
        expected values of output variables `pythondir' and `pyexecdir',
        since they can change quite unpredictably among different python
        installations.  Also, avoid "hyping" debugging output, thus
        offering smaller trace output and more informative diff.
        Report and suggestions by Ralf Wildenhues.
        * tests/python-virtualenv.test: Require python, since we call it
        even after the virtualenv has been deactivated.  Ignore cached
        values from config.site by exporting CONFIG_SITE=/dev/null.

        tests: tweak few tests on simple and parallel test drivers
        * tests/check-exported-srcdir.test: Improve heading comments.
        * tests/check-tests-in-builddir.test: Likewise.  Also, unset the
        `FOO_EXIT_STATUS' variable, so that any pre-existing value in the
        environment won't risk to interfere with the test.
        Suggestions by Ralf Wildenhues.

2011-02-06  Stefano Lattarini  <stefano.lattarini@gmail.com>

        python: extend and improve tests, fix minor glitches
        * m4/python.m4 (AM_PATH_PYTHON): Ensure the "checking ..." messages
        from configure are always complete, even in case of failure.  Tiny
        cosmetic improvement in info/error messages.
        * tests/python.test: Also check that automake complains if the
        PYTHON primary is used but the `py-compile' script is not present.
        Make grepping of generated Makefile.in laxer w.r.t. whitespace.
        Add trailing `:' command.
        * tests/python2.test: Remove repeated calls aclocal: they are
        useless because configure.in is never modified.  Make grepping
        of automake stderr more comprehensive.  Remove the pre-existing
        `py-compile' file before trying to install it with `--add-missing'.
        Add trailing `:' command.
        * tests/python3.test: Add trailing `:' command.
        * tests/python11.test: Likewise.
        * tests/python4.test: Likewise.  Also, try to pass PYTHON config
        variable to configure from the environment, rather than only from
        the command line.
        * tests/python5.test: Ensure that the "checking ..." messages from
        configure are always complete.  Use proper m4 quoting.  Add a
        trailing `:' command.
        * tests/python6.test: Simplify test logic, by checking for files
        created by configure rather then grepping its output.
        * tests/python7.test: Likewise.
        * tests/python8.test: Also check that `$PYTHON' is meaningfully
        set in the ACTION-IF-TRUE argument of AM_PATH_PYTHON.
        * tests/python9.test: Likewise.
        * tests/python10.test: Add trailing `:' command.
        (Makefile.am): Declare `disttest' target as `.PHONY', and add
        an `ls -l' to its recipe, for debugging.
        * tests/nobase-python.test: In testing "make uninstall" and
        "make install" results, prefer idioms that make verbose logs
        more helpful.  Remove a couple of lines of dead code.  Add a
        trailing `:' command.
        * tests/python5b.test: New test, checking that configure performs
        the check on the python version even when the choice of the python
        interpreter is forced by the user.
        * tests/python-dist.test: New test, checking the distribution of
        *_PYTHON files.
        * tests/python-vars.test: New test, checking that AM_PATH_PYTHON
        correctly set all the output variables advertised in the manual.
        * tests/python-virtualenv.test: New test, checking that python
        support offered by automake works well with "virtual python
        environments" created by the `virtualenv' program.
        * tests/instdir-prog.test: Also check `$(pyexecdir)'.  Existing
        checks made slightly stricter.
        * tests/instdir-prog.test: Also check `$(pyexecdir)'.  Existing
        * tests/instdir-ltlib.test: Likewise.
        * tests/Makefile.am (TESTS): Update.

        docs: color-tests issues with parallel make
        * doc/automake.texi (Simple Tests): Document that automatic
        recognition of a capable terminal attached to stdout can fail
        with some make implementation when running in parallel mode,
        thus causing colored test output not to be automatically
        activated when it should.

2011-01-23  Stefano Lattarini  <stefano.lattarini@gmail.com>

        coverage: test semantics of "dummy" per-target flags

        per-target flags triggers the use of renamed objects.
        * tests/Makefile.am (TESTS): Update.
        Suggestion by Ralf Wildenhues.

2011-01-23  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tests: avoid instspc* failures due to make's whitespace trimming
        * tests/instspc-tests.sh: Prepend './' when passing the test
        characters, to avoid leading whitespace characters to be trimmed
        from macros set from environment variables.  Fixes testsuite
        failures with HP-UX and Tru64/OSF make.

2011-01-22  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        tests: fix VPATH auto-expansion workarounds.
        * tests/suffix10.test, tests/suffix11.test, tests/suffix12.test,
        tests/suffix3.test, tests/suffix5.test, tests/suffix8.test:
        Ensure $< is not surrounded by white space, to prevent Solaris
        make from applying automatic VPATH text expansion.

        tests: fix VPATH auto-expansion workarounds.
        * tests/parallel-tests8.test, tests/suffix13.test:

        * tests/yflags2.test: Likewise.

2011-01-22  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        tests: avoid fn99*.test failures due to buggy AIX 5.3 cp -R.
        * tests/fn99.test, tests/fn99subdir.test: Skip if an initial
        `cp -R' of the subdir tree already fails; AIX 5.3 cp messes
        up its internal memory when copying this tree.

2011-01-22  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>
            Stefano Lattarini  <stefano.lattarini@gmail.com>

        * lib/am/check.am (check-TESTS): Update comment.

2011-01-20  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        tests: less strict double-colon spy.test again.
        * tests/spy.test: We know BSD make doesn't invoke more than one
        double-colon rule, so no need to expose that failure.

2011-01-19  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        install-sh: avoid Tru64 sh `test' operator precedence issues.
        * lib/install-sh: Protect file names and directory components
        that consist of `=', `(', `)', or `!'.  Move protection as early
        as possible, to avoid errors such as with Tru64 sh `test -z ='.
        * tests/instsh2.test: Extend test to cover more possibilities.
        Fixes 1.12 instspc-equal-install.test failure on Tru64/OSF 5.1.

        docs: automake testsuite doesn't use TESTS_ENVIRONMENT anymore
        * doc/automake.texi (Simple Tests): Do not claim Automake uses
        TESTS_ENVIRONMENT for the perl driver.  Instead, point to the
        parallel-tests driver.

2011-01-21  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        tests: check for presence of cscope with redirected input.

        Fixes cscope3.test hang with Sun C 5.9 cscope.

        tests: avoid false failure in cygnus-dependency-tracking.test.
        * tests/cygnus-dependency-tracking.test: Be less restrictive
        when grepping the compiler error message, GCC 3.4.6 on FreeBSD
        does not mention an undefined symbol.

2011-01-20  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        tests: revert not turning off errexit in instspc-test.sh
        * tests/instspc-tests.sh: Turn off errexit while sourcing defs,
        the scripts might still not be clean.

2011-01-19  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        tests: work around Tru64 sh -e issues for instspc*.test.
        Apparently, Tru64 sh does not like turning off errexit mode,
        and gets confused.
        * tests/defs: Document 'errexit' cleanliness requirement.
        * tests/defs-static.in: Likewise.  Avoid error from command
        substitution to abort instspc*.test with Tru64/OSF 5.1 sh.
        * tests/instspc-tests.sh: Drop now-unneeded temporary errexit
        dropping.  Add strategic '|| Exit' to let tests work on Tru64.

        * tests/vartypo2.test, tests/vartypos.test: Rewrite to not use
        a command substitution with a nonzero exit status, that causes
        IRIX and Tru64/OSF sh to fail the whole test.

        parallel-tests: work around Tru64/OSF 5.1 sh read bugs.
        * lib/am/check.am ($(TEST_SUITE_LOG), recheck, recheck-html):
        Test file readability before redirecting input from it, to avoid
        exiting Tru64/OSF 5.1 sh which treats read as special builtin.
        * tests/parallel-tests-unreadable-log.test: New test.

        tests: hard error in case of internal failures or signal caught
        * tests/defs: Exit with status 99 (hard error) rather than
        1 (failure) on unexpected/internal errors, or when a signal
        is caught by the client script.

        Tests defs: don't let useless variables leak in test scripts.
        * tests/defs ($priv_check_temp, $overwrite_status, $ro_dir_temp,
        $create_status, $r2h, $libtool_found, $gettext_found, $aclocaldir,

        Fix parallel-tests.test failure with HP-UX make.
        * tests/parallel-tests.test: Sleep inside inner tests, so logs

2011-01-15  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        docs: ensure example are separated with empty lines in the input
        * doc/automake.texi (Extending aclocal, Emacs Lisp, Rebuilding)
        (API Versioning, Renamed Objects, Multiple Outputs): Add empty

        tests: fix spurious failures in two texinfo tests
        * tests/txinfo.test ($required): Add 'makeinfo'.
        * tests/txinfo8.test: Create a dummy 'textutils.info' file, so
        that make won't try to run makeinfo (which could be unavailable)
        to build it.
        Found by NixOS Hydra, reported by Ralf Wildenhues.

2011-01-15  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Update docs w.r.t. warning and strictness options.
        * doc/automake.texi (Strictness): Document that some warnings are
        turned off by default in `foreign' strictness.
        (Options): Divide into new sections "Options generalities" and
        "List of Automake options".  Fix typo (colon instead of full
        stop).  Document option precedence (AUTOMAKE_OPTIONS wins over
        AM_INIT_AUTOMAKE which wins over command line).  Also document
        interactions between options specifying strictness and those
        specifying warnings.

        More tests on warnings/strictness precedence.
        * tests/warning-groups-win-over-strictness.test: New test, similar
        to `warnings-win-over-strictness.test', but checking the explicit
        catch-all warning flags (like `-Wall' and `-Wnone').
        * tests/Makefile.am (TESTS): Update.

        Update NEWS about the warnings-over-strictness precedence.
        * NEWS: Automake explicit warning levels always take precedence
        over the implicit warning levels implied by Automake strictness.

        For PR automake/547:
        Warnings win over strictness in AUTOMAKE_OPTIONS.
        Ensure that, for what concerns the options specified in
        AUTOMAKE_OPTIONS, explicitly-defined warnings always take
        precedence over implicit strictness-implied warnings.
        This finally fixes Automake bug#7669 a.k.a. PR/547.
        * automake.in (handle_options): Call 'process_option_list'
        only once per set of options.
        * lib/Automake/Options.pm (process_global_option_list,
        process_option_list): Add sanity checks.
        ($_options_processed, $_global_options_processed): New
        internal variables, used by the sanity checks above.
        * tests/warnings-win-over-strictness.test: Extend.

        For PR automake/547:
        Change signature of 'Automake::Options::_process_option_list()'.
        This only modifies internal details in the automake implementation,
        bearing no externally visible effect, but preparing the way for the
        final fix of Automake bug#7669 a.k.a. PR/547.
        * lib/Automake/Options.pm (_process_option_list): Accept as
        arguments a list of hash references with keys 'option' and 'where',
        where 'option' is an option as might occur in AUTOMAKE_OPTIONS or
        AM_INIT_AUTOMAKE, and 'where' is the location where it occurred.
        (process_option_list, process_global_option_list): Updated.
        * automake.in (handle_options, scan_autoconf_traces): Update.

        Add more tests about AUTOMAKE_OPTIONS.
        In view of soon-to-follow refactorings (still in the pursuit of a
        fix for Automake bug#7669 a.k.a. PR/547), add some more tests on
        AUTOMAKE_OPTIONS support, to prevent obvious regressions.
        * tests/amopts-variable-expansion.test: New test.
        * tests/amopts-location.test: Likewise.
        * tests/Makefile.am (TESTS): Update.

        For PR automake/547:
        Warnings win over strictness in AM_INIT_AUTOMAKE.
        This change ensures that, for what concerns the options specified
        in AM_INIT_AUTOMAKE,  explicitly-defined warnings always take
        precedence over implicit strictness-implied warnings.  Related to
        Automake bug#7669 a.k.a. PR/547.
        * lib/Automake/Options.pm (_process_option_list): Parse explicit
        warnings only after the strictness level has been set.  Fix POD
        documentation.
        * tests/warnings-win-over-strictness.test: Extend.

        For PR automake/547:
        Warnings win over strictness on command line.
        Ensure that, on the command line at least, explicitly defined
        warnings always take precedence over implicit strictness-implied
        warnings.  Related to Automake bug#7669 a.k.a. PR/547.
        * automake.in (parse_arguments): Parse warnings only after the
        strictness level has been processed.
        * tests/gnuwarn.test: Update, plus miscellaneous improvements.
        * tests/warnings-win-over-strictness.test: New test.
        * tests/Makefile.am (TESTS): Update.

        tests: avoid spurious failures due to fork failure in test setup
        * tests/defs: Ensure $me is always nonempty, to avoid spurious
        failures on MinGW/MSYS in case the preceding sed command could
        not be spawned.

        Avoid configure warnings from wait about reused PIDs.

        * tests/automake.test: Added trailing `:' command.  Removed
        redundant checks on `--help' and `--version' option (already

2011-01-11  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tests: texinfo unrecognized extensions
        * tests/txinfo-unrecognized-extension.test: New test.
        * tests/Makefile.am (TESTS): Update.

        Improve, extend and tweak tests on Texinfo support.
        * tests/instdir-texi.test: Add a call to `ls -l' after that to
        `make', for debugging.  When looking for required tools, do not
        redirect the output of "$tool --help" to /dev/null, and do not
        uselessly run it in a subshell.
        * tests/txinfo.test: Rewritten to run autoconf, ./configure and
        make.  All checks moved into Makefile.am.
        * tests/txinfo8.test: Likewise, and modernize the generated
        configure.in.
        * tests/txinfo2.test: Moved checks into Makefile.am, and other
        minor improvements.
        * tests/txinfo5.test: Enable `errexit' shell flag, and related
        changes.  Add trailing `:' command.
        * tests/txinfo6.test: Likewise, and make grepping of generated
        Makefile.in stricter.
        * tests/txinfo7.test: Enable `errexit' shell flag, and related
        changes.  Add trailing `:' command.  Do not add unnecessary stuff
        to Makefile.am.
        * tests/txinfo9.test: Verify that more targets which are expected
        to be generated only once really are.  Make grepping less strict,
        to avoid exposing too much internal details.  More minor changes.
        * tests/txinfo16.test: Add trailing `:'.  Prefer cat over echo
        for appending to configure.in.  Updated/fixed heading comments.
        * tests/txinfo23.test: Likewise, and extended a little by making
        it check that no info file is created in the $(srcdir).
        * tests/txinfo24.test: Likewise.
        * tests/txinfo25.test: Likewise.
        * tests/txinfo18.test: Add trailing `:'.  Prefer cat over echo
        for appending to configure.in.  Also, check that index files are
        cleaned also by "make clean", not only by "make distclean".
        * tests/txinfo22.test: Prefer `$me' over hard-coded test name,
        and added trailing `:' command.  This testcase also used to check
        that automake ignores in-line comments when using variables, but
        preserves them in the output; these checks (added in commit
        "Release-1-7f-4-g9177ef8") do not really pertain to this test,
        so they have been moved ...
        * tests/comments-in-var-defn.test: ... into this new test.
        * tests/txinfo4.test: Escape literal dots in grep regexps.  Add
        trailing `:' command.
        * tests/txinfo29.test: Likewise.  Relax grepping of generated
        Makefile.in w.r.t. whitespaces.  Prefer `cat' over `echo' to
        append to configure.in.
        * tests/txinfo3.test: Likewise.
        * tests/vtexi.test: Improve grepping of Makefile.in (sometimes
        make it stricter, sometimes laxer).  Move `set -e' setting just
        after the inclusion of ./defs.  De-uglify a sed command.  Other
        minor cosmetic improvements.
        * tests/vtexi2.test: Make grepping of Makefile.in stricter.  Add
        trailing `:' command.
        * tests/vtexi3.test: New test on version.texi support.
        * tests/vtexi4.test: Likewise.

        * automake.in (lang_yacc_target_hook): Warn if any of the relevant

        exposes automake bug#7800 -- "automake fails to honor `-d' in
        AM_YFLAGS when variable expansions are involved".
        * tests/yflags-d-false-positive.test: New test, checking that
        automake do not spuriously see `-d' in *YFLAGS when that isn't
        really there.
        * tests/yflags-force-override.test: New test, checking that
        automake can cope with definition of the YFLAGS variable in
        Makefile.am (even if that is an extremely bad practice, as that
        variable is user-reserved).
        * tests/yflags-cmdline-override.test: New test, checking that
        automake can cope with user-redefinition of YFLAGS at configure

        * tests/lex.test: Don't create useless dummy source file joe.l.

        useless lex source file.
        * tests/lex2.test: Likewise.  Call automake with the `-a' option,
        so that it doesn't fail for the absence of `ylwrap' script.  Make
        grepping of automake stderr stricter.
        * tests/yacc7.test: Add trailing `:' command.  Enable `errexit'
        shell flag earlier (just after having sourced ./defs).
        * tests/yacc4.test: Likewise.  Also ...
        (configure.in): Use pre-populated skeleton set up by ./defs,
        instead of writing one from scratch.
        Other minor cosmetic changes.
        * tests/yacc5.test: Likewise.

        grepping the distribution tarball.  Extend the test on the
        created binary, and be sure to avoid hangs.  Add some comments.
        * tests/yacc.test: Use stricter grepping.  Add trailing `:'.
        * tests/yacc6.test: Likewise.
        * tests/yacc3.test: Likewise.  Do not create the unused file
        `Makefile.sed'.  Remove useless rules from Makefile.am.  Other
        minor cosmetic changes.
        * tests/yacc2.test: Make grepping of generated `Makefile.in' and
        of automake error messages stricter.  Do not redirect output of
        grep to /dev/null.  Move call to aclocal earlier.  Reduce the
        number of empty blank lines.  Fix a typo in comments.
        * tests/yacc8.test: Fixed bugs that reduced the completeness of
        the tests.  Added trailing `:' command.
        (configure.in): Use pre-populated skeleton set up by ./defs,
        instead of writing one from scratch.
        * tests/yaccpp.test: Test also extensions `.y++', `.ypp', and

        yacc: "make clean" removes .c and .h files from non-distributed .y
        Previously, while automake did *not* distribute C source and header
        files derived from non-distributed Yacc sources, it still caused
        them to be removed only by "make maintainer-clean" only, and not by
        simply "make clean" or "make distclean".
        This caused "make distcheck" to fail, unless the developer put
        those generated .c and .h files in CLEANFILES or in DISTCLEANFILES
        by hand.
        This change fixes this issue, by making non-distributed `.c' and
        `.h' files generated by non-distributed Yacc sources cleaned by
        "make clean".
        * tests/automake.in (lang_yacc_target_hook): Make C source and
        header files derived from non-distributed Yacc files cleaned by

2010-12-23  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Improve and extend tests `suffix*.test'.
        * tests/suffix.test: Check that suffix rules for C compilation are
        only included once.  Try also with a static library.
        * tests/suffix2.test: Add a new grep to help potential debugging.
        Do not run automake with the `--add-missing' options, since we
        already create all the needed auxiliary files.  Try also *without*
        the `no-dependencies' automake option.
        * tests/suffix4.test: Make grepping of Makefile.in stricter.
        * tests/suffix3.test: Rewritten to run also autoconf, ./configure
        and make.
        * tests/suffix5.test: Likewise.
        * tests/suffix6.test: Fix botched recipe indentation (eight spaces
        were used instead of a tabulation character).  Extend to check
        that `.obj' is handled like `.$(OBJEXT)' (as is done for `.o').
        Improved parsing & grepping of generated Makefile.in.  Other minor
        fixes and improvements.
        * tests/suffix10.test: Move some checks in Makefile.am.  Also run
        "make all".
        * tests/suffix12.test: Likewise, and account for VPATH issues in
        weaker make implementations.
        * tests/suffix11.test: Likewise.  Also, run "make distcheck", for
        completeness, and related changes.
        * tests/suffix8.test: Likewise.  Also, do not put `gcc' anymore
        in $required.
        * tests/suffix13.test: Do not use the `--force-missing' automake
        option unnecessarily.
        * tests/suffix6b.test: New test, semantic sister of `suffix6.test'.
        * tests/suffix6c.test: Likewise.
        * tests/Makefile.am (TESTS): Updated.

            Stefano Lattarini  <stefano.lattarini@gmail.com>

        Work around a bug in file-inclusion mechanism of Solaris make.
        * automake.in (handle_single_transform): In the name of the
        dependency file: collapse multiple slash characters into a single
        one.
        * tests/subobj11a.test: New test.
        * tests/subobj11b.test: Likewise.

        patch and tests by Stefano Lattarini.

2010-12-22  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Fix two spurious testsuite failures on IRIX 6.5.
        * tests/suffix13.test (Makefile.am): Account for VPATH issues on
        weaker make implementations (e.g. IRIX 6.5).
        * tests/parallel-tests8.test: Likewise, plus a required related
        change.
        Reported by Ralf Wildenhues.  The bugs have been there from the
        first versions of the affected test scripts.

2010-12-22  Stefano Lattarini  <stefano.lattarini@gmail.com>

        docs: cygnus mode doesn't require AM_CYGWIN32 macro.
        * doc/automake.texi (Cygnus): Mode 'cygnus' does not require
        the AM_CYGWIN32 macro (and indeed hasn't required it since at
        least commit Release-1-2-31-g3038064 "merged changes from
        Cygnus" of 1997-08-25).

2010-12-22  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Add some tests on 'cygnus' mode.
        * tests/clean2.test: Extend.
        * tests/cygnus-check-without-all.test: New test.
        * tests/cygnus-dependency-tracking.test: Likewise.
        * tests/cygnus-distclean.test: Likewise.

2010-12-22  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Fix parallel testsuite run with Zsh.
        This change deals with a Zsh incompatibility in the handling
        of the special shell variable `$0' in sourced files; this
        incompatibility used to cause utter breakage when the
        Automake testsuite was run in parallel mode with Zsh as
        the $(TEST_LOG_COMPILER).
        For more information, please refer to the thread "Fix parallel
        testsuite run with zsh" on automake-patches, dated 2010-12-22:
         <http://lists.gnu.org/archive/html/automake-patches/2010-12/msg00135.html>
        This change works around the problems described above for Zsh 4.3
        or later, and offers better error messages (instead of random
        failures) for earlier Zsh version.
        * tests/README (Supported shells): When describing the manual
        workaround about the Zsh incompatibility in the handling of `$0',
        tell that it is now needed only with Zsh versions preceding 4.3.
        Done also some minor rewordings.
        * tests/defs-static.in ($argv0): New variable, offers a workaround
        for the Zsh incompatibility in the handling of `$0'.
        Abort if that variable cannot be correctly set (can happen only
        in older Zsh version).
        * tests/defs ($me): Define using `$argv0', not `$0'.

2010-12-22  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Tests defs: keep track of original $AUTOMAKE and $ACLOCAL values.
        This is especially useful for tests which might want to run
        automake and aclocal without additional flags and warnings.
        * tests/defs-static.in ($original_ACLOCAL): New variable.
        ($original_AUTOMAKE): Likewise.
        * tests/help.test: Use them.
        * tests/help2.test: Likewise.
        * tests/help3.test: Likewise.
        * tests/help4.test: Likewise.
        From a suggestion by Ralf Wildenhues.

2010-12-22  Stefano Lattarini  <stefano.lattarini@gmail.com>

        distlinksbrk.test: Work around botched "make -k".
        * tests/distlinksbrk.test: Run "make" multiple times and grep
        its output each time for a single error message, rather than
        running "make -k" one single time and grepping its output for
        all the expected error messages.  This should work around make
        implementations with limited (broken?) `-k' support; for more
        information, see these subthreads on the automake-patches list:
          - 2010-11-15, "Testsuite failures on HP-UX 11.23",

2010-12-21  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Minor improvements to test 'amopts.test'.
        * tests/amopts.test: Remove botched comment.  Make grepping of
        automake stderr slighty stricter.  Add trailing `:' command.

2010-12-21  Stefano Lattarini  <stefano.lattarini@gmail.com>

        backcompat6.test: avoid comments inside recipe commands.
        * tests/backcompat6.test: Remove shell comments from makefile rule
        commands, as they are not portable to (at least) Tru64 make.

2010-12-21  Stefano Lattarini  <stefano.lattarini@gmail.com>

        man8.test: avoid comments inside recipe commands.
        * tests/man8.test: Remove shell comments from makefile rule
        commands, as they are not portable to (at least) Tru64 make.

2010-12-21  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Fix sed-related buglet in test "subdir5.test"
        * tests/subdir5.test: Always terminate text passed to the
        `i' sed command with a newline, to work around limitations
        in e.g. older OpenBSD sed.

2010-12-21  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Fix spurious failures in tests on AC_CONFIG_AUX_DIR.
        * tests/auxdir7.test: Do not try to needlessly overwrite the files
        `install-sh' and `missing'.  This avoid spurious failures in "make
        distcheck", when those files might be copied as read-only from the
        `lib' directory.
        * tests/auxdir8.test: Likewise.

2010-12-18  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Make test 'posixsubst-script' portable to MinGW/MSYS.
        * tests/posixsubst-script.test: Ensure that the generated dummy
        scripts really start with a shebang line, to work around a
        limitation of 'test -x' on MinGW/MSYS.
        Reported by Ralf Wildenhues.

        Improve comments in tests `posixsubst*.test'.
        * tests/posixsubst-data.test: Improve comment explaining why we
        try also empty match suffix.

        docs: fix blunder in example about python extension modules
        * doc/automake.texi (Python): Use `quaternion_la_SOURCES',
        not `quaternion_SOURCES', to declare the sources of python
        extension module `quaternion.la'.

2010-12-16  Stefano Lattarini  <stefano.lattarini@gmail.com>

        docs: list LTLIBRARIES among Automake primaries
        * doc/automake.texi (Uniform): List `LTLIBRARIES' among

        XSI-conformance checks in sync with libtool.

2010-12-17  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Minor cleanups in canon7.test.
        * tests/canon7.test (_foo_bar_SOURCES): Remove libs.c.
        (configure.in): Remove AC_PROG_CXX.

2010-12-16  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Avoid false positive in sc_tests_plain_make maintainer-check.
        * Makefile.am (sc_tests_plain_make): Ensure to only match full
        `make' words.  Avoid false positive with remake11.test.

2010-12-16  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Fix canon7.test failure.
        * tests/canon7.test (_foo_bar_SOURCES): Add foobar.c.

        Fix typos in test comments.
        * tests/posixsubst-data.test, tests/posixsubst-extradist.test,
        tests/posixsubst-ldadd.test, tests/posixsubst-libraries.test,
        tests/posixsubst-ltlibraries.test, tests/posixsubst-programs.test,

        tests/posixsubst-tests.test: Fix typos.

2010-12-14  Stefano Lattarini  <stefano.lattarini@gmail.com>

        More uses of AS_HELP_STRING in automake macros.
        * m4/depend.m4 (AM_DEP_TRACK): Use `AS_HELP_STRING' to format
        the help message added to the generated configure.
        * m4/dmalloc.m4 (AM_WITH_DMALLOC): Likewise.
        * m4/lispdir.m4 (AM_PATH_LISPDIR): Likewise.
        * m4/maintainer.m4 (AM_MAINTAINER_MODE): Likewise.
        * m4/multi.m4 (AM_ENABLE_MULTILIB): Likewise.
        Also, bumped all serial numbers of the modified m4 files.

2010-12-14  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Improve tests on generated portions of configure help screen.
        * tests/help-depend.test: Grepping of configure help screen
        relaxed to cater for possible line wrapping, and tightened in
        other respects.
        * tests/help-depend2.test: Likewise.
        * tests/help-dmalloc.test: Likewise.
        * tests/help-lispdir.test: Likewise.

2010-12-15  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Extended tests on AC_CONFIG_AUX_DIR.
        * tests/auxdir.test: Enable `errexit' shell flag.  Prefer `$me'
        over hard-coded test name.  Use proper m4 quoting.  Add trailing
        `:' command.
        * tests/auxdir2.test: Likewise.  Try to call automake also with
        the `-a' option, so that it will not fail for spurious reasons.
        * tests/auxdir3.test: Add an explanatory comment and a trailing
        `:' command.
        * tests/auxdir4.test: Prefer `$me' over hard-coded test name.
        Make grepping of automake stderr slightly stricter.  Also, now
        this test just checks about Automake's reaction to unportable
        auxiliary directory names (and it has been extended in this
        respect).  Moved the checks about non-existent auxiliary
        directories to ...
        * tests/auxdir5.test: ... this new test.
        * tests/auxdir6.test: New test.
        * tests/auxdir7.test: Likewise.
        * tests/auxdir8.test: Likewise.

2010-12-06  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Tests: extend checks on remake rules.
        This adds proper semantical tests (i.e. run make to check the
        rebuild rules are correctly triggered) in addition to tentative
        grepping of the generated Makefile.in(s).
        * tests/remake.test: Enable `errexit' shell flag, and related
        changes.  Modernize `configure.in'.  Add trailing `:' command.
        Improve heading comments, and add a reference to new sister test
        remake1a.test.
        * tests/remake3.test: Likewise (but with sister test being
        remake3a.test).
        * tests/remake2.test: Improve heading comments.  Enable `errexit'
        shell flag, and related changes.  Modernize `configure.in'.  Make
        grepping of `Makefile.in' slightly stricter.  Add trailing `:'
        command.
        * tests/remake5.test: Also run the `distcheck' target.  Add
        trailing `:' command.  Use proper m4 quoting in configure.in.
        * tests/remake4.test: Prefer `$me' over hard-coded test name.
        * tests/remake7.test: Use the `configure.in' stub created by
        ./defs, rather than writing it from scratch.
        * tests/remake6.test: Likewise.  Also, add trailing `:' command,
        and ensure verbose printing of captured make output.
        * tests/remake1a.test: New test, sister of remake.test.
        * tests/remake3a.test: New test, sister of remake3.test.
        * tests/remake8a.test: New test.
        * tests/remake8b.test: Likewise.

        * tests/Makefile.am (TESTS): Updated.

2010-12-11  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Improve and extend tests on canonicalization.
        * tests/canon-name.test: Add trailing `:' command.  When writing
        configure.in, prefer to use $me instead of hard-coding the test
        name.
        * tests/canon3.test: Prefer trailing `:' over trailing `Exit 0'.
        * tests/canon4.test: Likewise.  Make grepping of Makefile.in
        stricter.  Improve heading comment, and add reference to ...
        * tests/canon6.test: ... this new test (sister test of the
        previous one).
        * tests/canon.test: Prefer cat + here-doc over echo to append
        text to configure.in.  Extend grepping of Automake stderr.  Add
        trailing `:' command.
        * tests/canon5.test: Likewise.
        * tests/canon7.test: New file, stress test on canonicalization.
        * tests/canon8.test: New test, for better coverage (check that
        the `@' character is not transliterated in canonicalizations).
        * tests/Makefile.am: Updated.

2010-12-13  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Libobj tests: refer to automake bug tracker for limitations.
        * tests/libobj15b.test (configure.in): In the comment explaining
        why an apparently redundant AC_OUTPUT is indeed needed, refer
        to the relevant entry in the Automake bug tracker rather than
        describing the bug in detail with a FIXME-style comment.
        * tests/libobj15c.test: Likewise.
        * tests/libobj20b.test: Likewise.

        Libobj tests: do not use `##' automake comments in-line.
        * tests/libobj19.test (Makefile.am): Do not use inline `##'
        comments in the definition of AUTOMAKE_OPTIONS.
        * tests/libobj20c.test: Likewise.
        Report by Ralf Wildenhues.

2010-12-12  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Tests defs: more uses of $top_testsrcdir.
        * tests/compile6.test: Use `$top_testsrcdir' instead of
        `$testsrcdir/..'.

2010-11-12  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Tests required tools: also try `-v' option for GNU compilers.
        * tests/defs.in: In the loop on "$required" tools, for gcc
        and g++, also run "gcc -v" (resp. "g++ -v"), to get more
        information, and for consistency with gcj.

2010-11-12  Stefano Lattarini  <stefano.lattarini@gmail.com>
            Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Tests defs: avoid some useless subshells.
        * tests/defs: In the loop on "$required" tools: avoid subshells
        where not needed.

2010-12-09  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Extend tests on AC_LIBOBJ and friends.
        * tests/aclibobj.test: Removed, superseded by ...
        * tests/libobj-basic.test: ... this new test, which runs autoconf,
        ./configure and make, to ensure everything really works.
        * tests/libobj3.test: Add trailing `:' command.  Escape literal
        dot in grep regexp.
        * tests/libobj4.test: Enable `errexit' shell flag, and related
        changes.  Add trailing `:' command.  Use proper m4 quoting.
        * tests/ltlibobjs.test: Likewise.
        * tests/libobj5.test: Enable `errexit' shell flag, and related
        changes.  Add trailing `:' command.  Make more robust by using
        longer filenames to be grepped.
        * tests/libobj8.test: Enable `errexit' shell flag, and related
        changes.  Add trailing `:' command.  Use the configure.in
        stub provided by ./defs, rather than writing it from scratch.
        * tests/libobj2.test: Likewise.  Also, add calls to autoconf,
        ./configure and make, to ensure everything really works.
        * tests/libobj7.test: Likewise, and ensure that at least one
        function listed in AC_REPLACE_FUNCTIONS is truly replaced.
        * tests/libobj13.test: Make grepping of Automake stderr slightly
        stricter.  Add trailing `:' command.
        * tests/libobj12.test: Likewise.  Also, prefer "cat + here-doc"
        over "echo" to append to Makefile.am, and some cosmetic changes
        in spacing.
        * tests/libobj14.test: Call `Exit 1' if sourcing of ./defs fails.
        Slighty improve m4 quoting.  Add trailing `:' command.
        * tests/libobj10.test: Add calls to autoconf, ./configure and
        make, to ensure everything really works.  Also, remove tests that

        Fix spurious failures in `silent*.test' for $CC != gcc
        In some tests on automake-produced silent rules, we forced the
        use of gcc depmode to improve testsuite coverage; but this has
        unsurprisingly led to spurious failures when some non-GNU C
        compilers were used.  So we are now careful to require GCC in
        tests that force gcc depmode.
        From reports by Ralf Wildenhues.

        * tests/silent-many-generic.test, tests/silent-many-gcc.test: ...

        separate sub-make invocations for empty and nonempty $(STRIP),
        to fix quoting issues.
        * tests/strip2.test, tests/strip3.test: New tests.
        * tests/Makefile.am (TESTS): Adjust.

2010-11-12  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Fix bug in test `backcompat6.test' (MSYS portability).
        * tests/backcompat6.test (Makefile.am): Grep the output from the
        test program, rather than diffing it, to avoid spurious failures
        on MinGW/MSYS due to LF vs. CRLF line endings.
        Reported by Ralf Wildenhues.

2010-11-13  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Deprecate obsolete macro AM_WITH_REGEX.
        * m4/regex.m4: Document the `AM_WITH_REGEX' macro as obsolete,
        and state that it should be removed two years from now.
        (AM_WITH_REGEX): Raise an m4-time warning of the "obsolete"
        category when this macro is used.
        * doc/automake.texi (Public Macros): Move description of
        `AM_WITH_REGEX' from here ...
        (Obsolete Macros): ... to here, and declare it as obsolete
        and "to be removed in a future version".
        * tests/regex-obsolete.test: New test.
        * tests/Makefile.am (TESTS): Update.

2010-11-08  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Improve and extend tests on man pages support.
        * tests/man.test: Enable `errexit' shell flag, and related changes.
        Make grepping of generated Makefile.in slightly stricter.
        * tests/man3.test:  Add trailing `:' command.
        * tests/man5.test: Prefer cat + here-doc over echo to append to
        configure.in.
        * tests/man2.test: Likewise, and add trailing `:' command.
        * tests/man4.test: More thorough and consistent checking of make
        error messages.  Place fake `help2man' program in a new `bin'
        directory rather than in `.'.  Move the checks using the real
        `help2man' program to ...
        * tests/man6.test: ... this new test, and extend them.  This test
        passes with GNU make and Solaris make, still fails with BSD make.
        * tests/man7.test: New test, extracted from old man4.test, which
        checks for a bug in maintainer-clean w.r.t. generated manpages.
        * tests/man8.test: New test, extracted from old man4.test, which
        checks for a bug in distcheck w.r.t. generated manpages.  Passes
        with GNU make and Solaris make, still fails with BSD make.

2010-11-08  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Minor improvements and extensions to various tests.
        * tests/defun.test: Also run autoconf and grep the generated
        configure to make sure that aclocal truly picks up all the
        required macros.
        * tests/compile_f_c_cxx.test: Prefer trailing `:' over trailing
        `Exit 0'.  Do not create useless dummy source files.  Do not set
        useless `$(foo_LDADD)' variable in `Makefile.am'.  Do not call
        useless macro `AC_F77_LIBRARY_LDFLAGS' in `configure.in'.
        * tests/compile_f90_c_cxx.test: Likewise.
        * tests/suffix10.test: Slightly stricter grepping of make output.
        * tests/compile.test: Add trailing `:' command.
        * tests/defun2.test: Likewise.
        * tests/vars3.test: Likewise.
        * tests/vartar.test: Likewise.
        * tests/vars.test: Likewise.  Also, extend test by checking
        that the definition of `MY_FLAGS*' variables is preserved in
        the generated `Makefile.in'.
        * tests/stamph2.test: Prefer trailing `:' over trailing `Exit 0'.
        Use proper m4 quoting in `configure.in'.

2010-11-11  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Tests defs: improve messages for skipped tests.
        * tests/defs: Give meaningful messages about the reasons of a
        test skip; this is especially useful as this file is run without
        verbose xtraces on.  Related reorderings in the code and new
        comments.

2010-11-10  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Tests defs: move static definitions in a new file `defs-static'.
        The new file is meant to be idempotent w.r.t. multiple inclusions.
        * tests/defs.in: Removed, its contents split among ...
        * tests/defs-static.in: ... this new file ...
        * tests/defs: ... and this new file, including the former.
        * configure.ac (AC_CONFIG_FILES): Remove `tests/defs', add
        `tests/defs-static'.
        (AC_CONFIG_LINKS): Add `tests/defs'.
        * tests/Makefile.am ($(parallel_tests)): Update.
        ($(instspc_tests)): Likewise.
        * tests/.gitignore: Update.

        Tests defs: $testsbuilddir is now AC_SUBST'ed.
        * tests/defs.in ($testsbuilddir): Substitute from @abs_builddir@.
        Add sanity check on $testsbuilddir, similar to those on
        $testsrcdir and $top_testsrcdir.

        Tests defs: do not print message "Running test $0" anymore.
        * tests/defs.in: Printing the message "=== Running test $0" at
        the beginning of each tests made sense when Automake used the old
        test-driver, which sent all the output directly to stdout/stderr.
        Now that the parallel test-driver is used, which saves output of
        each test in its corresponding log file, that old message is just
        useless noise.

        Tests defs: rename $curdir -> $testbuilddir
        * tests/defs.in: Rename $curdir to $testbuildir, for clarity and
        consistency with $testsrcdir and $top_testsrcdir.

        Tests defs: prefer "$curdir" over "`pwd`".
        * tests/defs.in: We already save the value of `pwd` in $curdir
        early in the file, so there no need to recalculate it later, when
        the current working directory is not changed.

        Tests defs: use `$me' in more error messages.
        * tests/defs.in: Also use `$me' in error messages referring to
        missing `defs' or `defs.in', since that variable is now defined
        before those checks.

        Tests defs: do not use `Exit' where plain `exit' suffices.
        * tests/defs.in: Use "exit 77" rather than "Exit 77" to skip the
        test when required libtool/gettext macros are not found, since
        such skips would take place before the exit trap is installed.

        Tests defs: improve and extends comments.
        * tests/defs.in: Improve and extends some comments, especially in
        relation with the changes introduced by the previous reordering.

        Tests defs: various reorderings.
        * tests/defs.in: Reordered various snippets of code in a
        clearer way.

2010-11-09  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Fix bug in test `backcompat4.test' (stale autom4te cache).
        * tests/backcompat4.test: Remove stale autom4te cache directory
        before re-running aclocal and automake.  Also, since we are at
        it, be more verbose in displaying contents of generated files,
        to ease debuggability.
        Reported by Ralf Wildenhues.

2010-11-07  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Fix a bug in variable concatenation with `+='.
        * lib/Automake/VarDef.pm (append): Since the content of the
        "appended-to" variable is going to be unconditionally normalized
        later, simply separate the appended value with a single whitespace
        character, instead of trying to be uselessly smarter by using
        escaped newlines.  This fixes a bug in which extra backslashes
        where erroneously inserted in the variable's final value.
        * tests/pluseq11.test: New test, exposing the bug.
        * tests/Makefile.am (TESTS): Update.
        Reported by Andy Wingo.

2010-11-07  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Modernize, improve and/or tweak various test scripts.
        * tests/stamph2.test: Improve m4 quoting in `configure.in', and
        prefer trailing `:' over trailing `Exit 0'.
        * tests/syntax.test: Escape literal dots in grep regexps.
        * tests/copy.test: Enable `errexit' shell flag.  Extend test by
        checking with `test' utility that the script `install-sh' is
        copied, but not symlinked.
        * tests/depdist.test: Move setting of `errexit' shell flag earlier
        in the script (just after inclusion of ./defs).  Avoid obsoleted
        constructs in generated `configure.in'.  Prefer to do our checks
        by running configure and make over grepping Makefile.in.
        * tests/target-cflags: Move setting of `errexit' shell flag
        earlier in the script (just after inclusion of ./defs). Use the
        `configure.in' stub created by `./defs', rather than writing it
        from scratch.
        * tests/target-clash: Do not uselessly run autoconf.
        * tests/ctarget1.test: Renamed ...
        * tests/cond-basic.test: ... to this.  Use the `configure.in' stub
        created by `./defs', rather than writing it from scratch.
        Move setting of `errexit' shell flag earlier in the script (just
        after inclusion of ./defs).  Other minor cosmetic changes.
        * tests/Makefile.am (TESTS): Updated.

2010-11-06  Stefano Lattarini  <stefano.lattarini@gmail.com>

        New tests on obsoleted usages of automake/autoconf macros (such
        as AC_INIT, AM_INIT_AUTOMAKE and AC_OUTPUT).
        * tests/backcompat.test: New test script.
        * tests/backcompat2.test: Likewise.
        * tests/backcompat3.test: Likewise.
        * tests/backcompat4.test: Likewise.
        * tests/backcompat5.test: Likewise.
        * tests/backcompat6.test: Likewise.
        * tests/init.test: Extended and improved, esp. by trying more
        combinations of calls to AC_INIT and AM_INIT_AUTOMAKE with few
        arguments.
        * tests/Makefile.am (TESTS): Updated.

2010-11-06  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Fix bug in rules for creating vala vapi/header files.
        * automake.in (lang_vala_finish_target): Add forgotten "fi" in an
        if control structure in a generated make rules.  Bug introduced
        by previous commit `v1.11-221-gd7c1679', and revealed by failure
        of test `vala2.test'.

2010-11-01  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Fix and document rules to not touch the tree with `make -n'.
        * doc/automake.texi (Multiple Outputs): Document the problem of
        modifications during dry-run execution, propose solution.
        * NEWS: Update.
        * automake.in (lang_vala_finish_target): Split recipe so the
        stamp file is not removed with GNU `make -n'.
        (lang_yacc_target_hook): Separate removal of parser output file
        and header remaking.
        * lib/am/lisp.am ($(am__ELCFILES)): Determine whether -n was
        passed to make, take care not to remove any files in that case.
        * lib/am/remake-hdr.am (%CONFIG_H%): Separate removal of
        %STAMP% file from induced remaking of config header.
        * tests/autohdrdry.test, tests/lispdry.test, tests/yaccdry.test:
        New tests.
        * tests/Makefile.am (TESTS): Update.

2010-11-05  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Fix potential bug in generated tests `instpc-*.test'.
        This bug is due to the changes introduced by the recently-merged
        "tests-init" branch.  In that branch, `tests/defs' didn't define
        anymore `$srcdir', instead defining directly `$testsrcdir'; but
        the generated tests were using `$srcdir', hence the bug.
        Luckily, since the Automake parallel test driver automatically
        exports `srcdir' to a proper value, that prevented the bug from
        manifesting itself.
        * tests/Makefile.am ($(instspc_tests)): In the generated test
        scripts, use `$testsrcdir', not `$srcdir'.

2010-11-03  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Overhauled and modularized tests in `instspc.test'.
        The test `instspc.test' was way too big and fragile.  Its running
        time was very long.  It also produced a log that was nearly
        unreadable due to its length, making it very difficult to find
        out the reason for failures.
        Also, it was too much monolithic, with a single (maybe spurious)
        failure in a corner case causing the whole test to fail (even if
        everything worked as expected in the other 99% of cases).
        The present change should solve these problems, by separating
        `instspc.test' into many smaller, self-contained, auto-generated
        tests.
        * tests/instspc.test: Removed.
        * tests/instspc-tests.sh: New script, fulfilling a double role:
        1. it generates a Makefile.am snippet `tests/instspc-tests.am',
        containing the definition of a list of new tests which will take
        over the older `instspc.test', and
        2. it is sourced by said generated tests with proper parameters
        pre-set, to run the "meat" of the checks.
        This apparent abuse is indeed required because the test generation
        code and test execution code are inevitably intertwined.
        * tests/Makefile.am ($(srcdir)/instspc-tests.am): Include this
        snippet, which (among the other things) defines ...
        (instspc_tests): ... this new macro, containing the list of the
        newly generated `instspc*.test' tests, and ...
        (instspc_xfail_tests): ... this new macro, containing the list
        of the `instspc*.test' tests expected to fail.
        ($(instspc_tests)): New rule, generates the `instspc*.test' tests.
        ($(instspc_tests:.test=.log)): New rule, registers the dependency
        of all `instspc*.test' tests on the `instspc-tests.sh' script.
        (TESTS): Add `$(instspc_tests)', remove `instspc.test'.
        (XFAIL_TESTS): Add `$(xfail_instspc_tests)'.
        (EXTRA_DIST): Distribute instspc-tests.sh.
        (MAINTAINERCLEANFILES): Added $(instspc_tests).
        Other minor cosmetic changes.
        * bootstrap: Generate instspc-tests.am.
        * tests/.gitignore: Updated.

2010-11-01  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Add FAQ entry for bug reporting instructions.
        * doc/automake.texi (Reporting Bugs): New section.

2010-10-07  Peter Rosin  <peda@lysator.liu.se>

        depcomp: add new one-pass depmode for MSVC 7 and later.
        * lib/depcomp: Add new depmodes 'msvc7' and 'msvc7msys' which
        make use of the -showIncludes option added in MSVC 7.
        * m4/depend.m4 (_AM_DEPENDENCIES): Handle the new depmodes
        similarly to 'msvisualcpp' and 'msvcmsys' as MSVC does not
        support the -o option.

2010-10-04  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Add support for newer python versions.
        * m4/python.m4 (AM_PATH_PYTHON): Add python2.7 and python3.2 to
        _AM_PYTHON_INTERPRETER_LIST.  Since we are at it, break a long
        line and fix indentation.
        * THANKS: Updated.
        From a report by Thomas Klausner.

        Add test for `AM_WITH_DMALLOC' macro.
        * tests/dmalloc.test: New test.
        * tests/Makefile.am (TESTS): Update.

        Fix nits and bugs in tests `help*.test'.
        * tests/help4.test: Fix broken sed commands used to strip `-W...'
        flags away from "$AUTOMAKE" and "$ACLOCAL".
        * tests/help3.test: Likewise, and fix a botched comment.
        * tests/help.test: Likewise.  Also, use "AUTOMAKE_fails ..."
        instead of "$AUTOMAKE ... && Exit 1", for consistency and to
        please maintainer-check.
        * tests/help2.test: Likewise.

        Improve tests `help*.test' (also fixes maintcheck failures).
        * tests/help.test: To run automake, use `$AUTOMAKE' with all `-W'
        flags stripped away rather than hard-coded `automake-$APIVERSION',
        to better honour user-overrides.  Similarly for aclocal.
        * tests/help2.test: Likewise.
        * tests/help3.test: Likewise.
        * tests/help4.test: Likewise.

2010-10-03  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        tests: fix ar-lib.test for echo that interprets backslashes.
        * tests/ar-lib.test: Use printf instead of echo.  Avoid test -a.
        More robust quoting.

        maintainer-check coverage for variables before rules.
        * Makefile.am (sc_ensure_testsuite_has_run): Suggest keeping
        around the test directories.

        catch ordering violations.

        Document and fix expansion of variables before rules.
        * doc/automake.texi (General Operation): Document that variables
        are expanded before rules.
        * lib/am/check.am (am__check_post): Reword a bit so it does not
        get matched as a rule.

        * NEWS: Update.
        Suggested by Eric Blake.

        tests: avoid running into timing issues due to sanity change.
        * tests/acloca10.test, tests/acloca18.test, tests/aclocal9.test:
        Insert strategic sleep before aclocal reruns, to ensure files
        are newer.
        * tests/python11.test: Use --force for repeated autotools runs.
        Reports from the NixOS Hydra build daemon via Ludovic Courtès.

        Fix timestamp issues by ensuring configure takes at least a second.
        * m4/sanity.m4 (AM_SANITY_CHECK): If we didn't sleep here,
        start a sleep in the background and wait for it to finish
        before creating config.status, hopefully fixing all spurious
        testsuite failures involving botched time stamps.
        * NEWS: Update.

2010-09-26  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Extend tests on `--help' and `--version' options.
        * tests/help.test: Create a new empty directory and chdir into
        it, rather than removing already present files.  Run the aclocal
        and automake wrapper scripts directly, instead of relying on
        $AUTOMAKE and $ACLOCAL.  Be sure to correctly match literal dots
        in aclocal's and automake's stderr.  Add a trailing `:' command.
        * tests/help2.test: New test, checking that options `--help' and
        `--version' works in directories with broken `configure.in'.
        * tests/help3.test: New test, checking that options `--help' and
        `--version' take precedence on the other options.
        * tests/help4.test: New test, checking that the first among the
        `--help' and `--version' options to be specified on the command
        line wins.

        computation of PATH_SEPARATOR again.
        * tests/instmany-mans.test: Use `$PATH_SEPARATOR', not `:', when

2010-09-22  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Manual: be more agnostic w.r.t. version control system used.
        * doc/automake.texi (Basics of Distribution): Also refer to `.svn'
        directories as a type of probably-unwanted files that are copied
        regardless when adding directories to EXTRA_DIST.
        (The dist Hook): Show a dist-hook example which removes Subversion
        `.svn' private directories from distdir, rather than CVS private
        directories.
        (missing and AM_MAINTAINER_MODE): Try to be more agnostic w.r.t.
        the version control system used.

        Manual: index refer to target "git-dist", not "cvs-dist".
        * doc/automake.texi (General Operation): Index the non-standard
        example about "git-dist" under the "git-dist" label, not under
        the "cvs-dist" one.

        Perl modules: remove references to "Automake CVS repository".
        * lib/Automake/Channels.pm: Update comments to refer to "Automke's
        git repository" rather than to "Automake's CVS repository".

        lib/Automake/.cvsignore, lib/Automake/tests/.cvsignore,
        m4/.cvsignore, tests/.cvsignore: Files deleted.  Even when using
        savannah's CVS readonly mirror there's no way to commit back to
        the real repository, so this files are not worth maintaining or
        keeping around.

2010-09-21  Stefano Lattarini  <stefano.lattarini@gmail.com>

        * m4/dmalloc.m4: Bump serial number and copyright years.

        Fix broken link in `AM_WITH_DMALLOC' help screen.
        * m4/dmalloc.m4 (AM_WITH_DMALLOC): Refer only to the dmalloc site
        `http://www.dmalloc.com', not to the dmalloc tarball there (which
        seems to have been removed, substituted by multiple release
        tarballs now).

2010-09-21  Peter Rosin  <peda@lysator.liu.se>

        compile: implement library search to support MSVC static linking
        * lib/compile (func_cl_wrapper): Implement library search and
        -static option so that the user can select whether to prefer
        dll import libraries or static libraries.  This enables MSVC to
        link against dlls generated by libtool without requiring libtool
        or workarounds such as -lfoo.dll etc.  Makes the tests/static.at
        test case in libtool pass.
        * tests/compile3.test: Don't trip up if there happens to exist
        a "foo" library in the library search path.
        * tests/compile6.test: New test, verifying the library search.
        * tests/Makefile.am (TESTS): Update.

        * Makefile.am (recheck, dist-hook, git-dist, path-check, fetch)
        (release-stats): Use `$(am__cd)' rather than plain `cd'.
        * tests/Makefile.am ($(srcdir)/parallel-tests.am): Likewise.

2010-09-12  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Fix regression in test `colon4.test'.
        * tests/colon4.test: Fix botched editing to `configure.in'
        that made the test useless.  Since we are at it, improve
        comments and make grepping of generated Makefile.in slightly
        stricter.
        Regression introduced by change "Modernize, improve and/or
        extend tests `colon*.test" (Stefano Lattarini, 2010-08-08).

2010-09-08  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Do not require "gzip" explicitly in tests.
        The gzip utility is simply expected to be present on any decent
        target system for Automake.  So it's pointless to put it in
        $required.
        * tests/install2.test ($required): Do not require "gzip".
        * tests/lex3.test: Likewise.
        * tests/pr9.test: Likewise.
        From a suggestion by Ralf Wildenhues.

2010-09-09  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Use AS_HELP_STRING in AM_SILENT_RULES.
        * m4/silent.m4 (AM_SILENT_RULES): Use `AS_HELP_STRING' to format
        help message regarding configure options `--enable-silent-rules'
        and `--disable-silent-rules'.  Also throw in a couple of cosmetic
        changes in the related `case' statement (indentation, balancing
        of parentheses).
        * THANKS: Update.
        From a report by Jeff A. Daily.

2010-09-08  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Make some `confh*.test' tests more "semantic" (plus tweakings).
        * tests/confh.test: Run "autoconf", "configure" and "make check",
        instead of munging/grepping the generated `Makefile.in'.
        * tests/confh4.test: Relax the grepping of Makefile.in w.r.t.
        white spaces.  Do not create useless dummy source file `foo.c'
        and useless dummy header file `acconfig.h'.
        (configure.in): Remove superfluous call to `AC_OUTPUT'.
        * tests/confh6.test: Add trailing `:' command.
        * tests/confh7.test: In comments, add reference to ...

        of `confh7.test'.
        * tests/Makefile.am (TESTS): Updated.
        Prompted by a report from Ralf Wildenhues.

2010-09-08  Stefano Lattarini  <stefano.lattarini@gmail.com>

        substitution %MAKEFILE%.
        (generate_makefile): Adjust.
        * lib/am/check.am [%?PARALLEL_TESTS%] (check-TESTS): Pass
        sanitized TEST_LOGS value as makefile snippet on standard
        input to $(MAKE), to avoid exceeding the command line limit on
        w32 (MSYS).
        * NEWS: Update.
        Report by Bob Friesenhahn.

        Posix 2008 requires make to set errexit.
        * lib/am/check.am: Update comment.

2010-09-06  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Tests defs: remove variable $testaclocaldir.

        * tests/aclocal.test: Use `$top_testsrcdir/m4' directly, not
        `$testaclocaldir'.

        * tests/defs.in ($srcdir): Remove, define $testsrcdir directly.
        * tests/Makefile.am ($(parallel_tests)): Generation of derived
        tests updated.

        Tests defs: new variable $top_testsrcdir.
        * tests/defs.in ($top_testsrcdir): Define unconditionally
        to @abs_top_srcdir@.  Use it throughout.
        * tests/ar-lib.test: Use `$top_testsrcdir' instead of
        `$testsrcdir/..'.
        * tests/auxdir.test: Likewise.

        Tests defs: $srcdir is unconditionally substituted.
        * tests/defs.in ($srcdir): Define unconditionally to @abs_srcdir@.
        Remove code for $srcdir normalization, which is now useless.

2010-09-02  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Tests defs: make spacing more consistent.
        * tests/defs.in: Make spacing more consistent in indentation.
        Especially, indent using only spaces, not tabs.  Also, move
        a comment to a better position.

        Improve code for requiring libtool and gettext in tests.
        * tests/defs.in: Stricter (and more correct) detection of wheter
        libtool, libtoolize and/or gettext are in $required.


2010-08-27  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Fix bug in test missing6.test.
        * tests/missing6.test: Fix the hack used to edit `configure.in',
        to avoid producing a configure script that breaks with shells
        that do not support $LINENO.  Also throw in a couple of cosmetic
        changes.

2010-09-02  Peter Rosin  <peda@lysator.liu.se>

        Make ar-lib support backslashed files in archives.
        * lib/ar-lib: If an archive member contains a backslash, make sure
        it is escaped when the archive member is extracted.
        * tests/ar-lib.test: Test the above.

2010-08-31  Peter Rosin  <peda@lysator.liu.se>

        * lib/am/ltlib.am (clean-%DIR%LTLIBRARIES): Rewrite using just
        one `rm' invocation.
        Report by Bob Friesenhahn.

        Improve robustness of mdate-sh script.
        * lib/mdate-sh: Sanitize zsh behavior on startup, to ensure
        $ls_command is word-split properly upon invocation.
        (error): New function.
        (main): Use it.  Improve error checking to avoid endless loop
        in case $ls_command gave bogus output.  Fix eval quotation.
        * tests/mdate6.test: New test, to expose eval quotation error.
        * tests/Makefile.am: Update.

2010-08-18  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Fix potential regressions in depcomp{3,5}.test.
        * tests/depcomp3.test: Do not uselessly escape the character `$'
        in makefile rules, when it's used to expand a make macro.
        * tests/depcomp5.test: Likewise.

2010-08-17  Stefano Lattarini  <stefano.lattarini@gmail.com>
            Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Docs: clarify how to avoid automatic dependencies tracking.
        * doc/automake.texi (Automatic dependency tracking): Mention that
        automatic dependencies tracking is enabled by default, but that
        the package developer can disable it altogether.  Add a reference
        to the proper section for a more in-depth explanation.

        Fix typo in manual (`Makefile.in' instead of `Makefile.am').
        * doc/automake.texi (Automatic dependency tracking): Fix typo.

2010-08-16  Bruno Haible  <bruno@clisp.org>

        Don't hide the table of contents.
        * doc/automake.texi: Move the table of contents to the beginning.

2010-08-16  Peter Rosin  <peda@lysator.liu.se>

        Optimize compile script on MSYS.
        * lib/compile (func_file_conv): Add new argument 'lazy' which
        takes an optional list of conversion types where the requested
        conversion isn't needed.
        (func_cl_wrapper): Take advantage of the above for cases where
        MSYS is doing the conversion for us.
        Suggested by Ralf Wildenhues.

2010-08-16  Peter Rosin  <peda@lysator.liu.se>

        Support more C++ file extensions for MSVC in the compile script.
        * lib/compile (func_cl_wrapper): MSVC only recognizes the .cpp
        file extension as C++, unless it's given a hint. So hint about
        .cc, .CC, .cxx, .CXX, c++ and C++. Also do path conversion on
        .c, .cpp, .CPP, .lib, .LIB and .Lib files.
        * tests/compile3.test: Test the C++ hinting.

        `cmp', and add some "cosmetic" blank lines.

2010-08-09  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Tweak and extend tests `pr[!0-9]*.test'.
        * tests/primary3.test: Add trailing `:' command.

        * tests/pr300-ltlib.test: Likewise, and ensure verbose printing
        of captured make stdout.
        * tests/pr211.test: Add trailing `:' command.  Also, use the
        `configure.in' stub created by ./defs, rather than writing it
        from scratch.
        * tests/pr204.test: Likewise, plus cosmetic spacing changes.
        * tests/pr287.test: Likewise, and move setting of `errexit' shell
        flag earlier in the script (just after inclusion of ./defs).

        Also, add trailing `:' command, and cosmetic changes in spacing.
        * tests/pr224.test: Move setting of `errexit' shell flag earlier
        in the script (just after inclusion of ./defs).  Do not export
        `CC=gcc' to configure explicitly (it's already exported globally
        in ./defs, since we have "gcc" in $required).  Use the stub for
        `configure.in' created by ./defs, rather than writing it from
        scratch.  Do not create dummy files required by "gnu" mode (e.g.
        README, NEWS), since we run automake in foreign mode anyway.
        * tests/pr72.test: Enable `errexit' shell flags, and related
        changes.  Extend existing checks a bit.
        * tests/pr9.test: Likewise.  Also, avoid obsolescent constructs in
        the generated `configure.in', and extend existing checks over the
        generated tarball a bit.
        * tests/pr87.test: Enable `errexit' shell flags, and related
        changes.  Add a trailing `:' command.  Also, do not create dummy
        files required by "gnu" mode (e.g. README, NEWS), since we run
        automake in foreign mode anyway.
        * tests/pr243.test: Avoid obsolescent constructs in the generated
        `configure.in'.  Enable the `errexit' shell flag, and related
        changes.  Cosmetic changes to spacing, add trailing `:' command,
        and add a "FIXME" comment.
        * tests/pr266.test: Likewise, and add explicit command line switch
        `--enable-dependency-tracking' to the ./configure call.
        * tests/pr279.test: Avoid obsolescent constructs in the generated
        `configure.in'; also, use the `configure.in' stub created by
        ./defs, rather than writing it from scratch.  Enable `errexit'
        shell flag, and related changes.  Add trailing `:' command.
        * tests/pr279-2.test: Likewise, and make grepping of Makefile.in
        stricter.
        * tests/pr307.test: Move setting of `errexit' shell flag earlier
        in the script (just after inclusion of ./defs).  Escape literal
        dots in grep regular expressions.  Also, add a trailing `:'
        command, and cosmetic changes to spacing.

        Modernize, improve and/or extend tests `colon*.test.
        * tests/colon.test: Rely on the `configure.in' stub created by

        * tests/confvar2.test: Likewise.
        * tests/conflnk3.test: Cosmetic changes.  Re-enable a temporarily
        disabled test (which didn't work with autoconf <= 2.59, but now we
        are requiring autoconf 2.62, so...)
        * tests/conflnk4.test: Cosmetic changes, and extend existing tests
        accordingly to "TODO" comments.
        * tests/conff2.test: Make grepping of Automake's stderr stricter.
        Add some comments explaining why we don't use the `configure.in'
        stub preset be ./defs.
        * tests/confh.test: Use the `configure.in' stub created by ./defs,
        rather than writing one from scratch, and do not call AC_OUTPUT.

        Add a trailing `:' command.
        * tests/depcomp2.test: Use `unset' on the CFLAGS variable to ensure
        it's not in in the environment, rather than exporting it with an
        empty value.  Do not pass CC=gcc to configure, as that's already
        done in ./defs since we have gcc in $required.  Ensure verbose
        printing of captured stderr, and normalize its checking.  Add a
        trailing `:' command.
        * tests/depcomp3.test: Quote literal dots and dollar characters in
        grep regexps.  Always use `: >' rather than `touch' to create empty

        Makefile.am.  Add a trailing `:' command.
        * tests/depcomp4.test: Quote literal dots and dollar characters in
        grep regexp.  Explicitly declare phony targets as such in the
        created Makefile.am.  Ensure verbose printing of captured makes'
        stoud/stderr.  Add a trailing `:' command.
        * tests/depcomp5.test: Move setting of `errexit' shell flag earlier
        in the script (just after inclusion of ./defs).  Quote literal dots
        and dollar characters in grep regexps.  Explicitly declare phony
        targets as such in the created Makefile.am.  Add a trailing `:'
        command.
        * tests/depcomp6.test: Consistently use m4 quoting in the generated
        configure.in.  Cosmetic fixes to spacing.  Make the "dummy" `if'
        statement required by OpenBSD's sh `set -e' more robust, and add
        explanatory comments to it.
        * tests/depcomp7.test: Likewise, and add  a trailing `:' command.

        Separate failing part of test `all.test'.
        * tests/all.test: Keep only (x)failing part of the test.  Working
        checks moved out to ...
        * tests/all2.test: ... this new test.

        `Makefile.in' stricter.
        * tests/subobj5.test: Add trailing `:' command.  Move setting of
        `errexit' shell flag earlier in the script (just after inclusion
        of ./defs).
        (configure.in): Use the stub created by `./defs', rather than
        writing it from scratch, and avoid obsolescent constructs.
        * tests/subobj6.test: Add trailing `:' command.  Move setting of
        `errexit' shell flag earlier in the script (just after inclusion
        of ./defs).  Do not create useless dummy ac-init file `f'.
        * tests/subobj7.test: Do not create useless dummy ac-init file
        `f'.
        (configure.in): Use the stub created by `./defs', rather than
        writing it from scratch, and avoid obsolescent constructs.
        * tests/subobj9.test: Move setting of `errexit' shell flag earlier
        in the script (just after inclusion of ./defs).  Fail the test if
        `make distcheck' fails.  Ensure verbose printing of captured make
        stdout.  Avoid useless fork by doing simple grep instead of using
        test -n "`COMMAND | grep ...`".
        (configure.in): Normalize the call to AC_INIT w.r.t. other tests.
        (Makefile.am): Explicitly mark target "print" as phony.
        * tests/subobj10.test: Removed duplicated call to `set -e'.  Add
        trailing `:' command.
        (configure.in): Normalize the call to AC_INIT w.r.t. other tests.

        Remove a couple of obsoleted tests.
        * tests/fpinstall.test: Removed.

        Bootstrap: fixlet.
        * bootstrap: Do not remove `lib/Automake/Config.pm' anymore,
        since we don't generate it.  Correctly quote arguments of
        `eval' builtin.  Fixed a botched error message.  Removed an
        extra blank line.

        Bootstrap: don't search perl in $PATH.
        * bootstrap: Do not explicitly search perl in $PATH anymore.
        ($PATH_SEPARATOR): Removed, it's no more needed.

        Bootstrap: let the user choose which autoconf to use.
        * bootstrap ($AUTOCONF): New variable, from the environment.
        ($AUTOM4TE): Likewise, for clarity.
        Use "$AUTOCONF" instead of calling "autoconf" directly.

        Minor improvements to tests ar*.test.
        * tests/ar.test: Add trailing `:' command.
        * tests/ar2.test: Likewise, and make grepping of generated

        Fix maintainer-check failure.
        * tests/cond5.test: Quote sleep argument, this isn't about
        time stamp differences.

        Sync auxiliary files from upstream.
        * lib/config.guess, lib/config.sub, lib/texinfo.tex:
        Sync from upstream.

2010-08-01  Peter Rosin  <peda@lysator.liu.se>

        Wrap some MSVC options in the compile script.
        * lib/compile: MSVC supports naming the output file, the option
        is just not called -o, so transform -o into the appropriate form
        for MSVC. Also wrap some other options while at it (-L, -l, -Wl,
        -Xlinker and -I) and convert file names to windows form where
        needed for those options to make MSVC more usable in an
        autotooled environment.
        * doc/automake.texi (Auxiliary Programs): Document the above
        extension of the compile script.
        * NEWS: Updated.

        variable, rather than re-evaluating the shell expression for
        the condition.
        * tests/cond40.test: Extend test.
        * NEWS: Update.

        Avoid syntax error if IF-TRUE part of AM_COND_IF expands empty.
        * m4/cond-if.m4 (AM_COND_IF): Ensure IF-TRUE part is never empty
        to avoid shell syntax error if the m4 expansion is empty.
        * tests/cond40.test: Enhance test.

        Coverage: bogus option to AM_INIT_AUTOMAKE.
        * tests/init2.test: New test.
        * tests/Makefile.am: Update.

2010-07-21  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Modernize and improve test scripts `subdir*.test'.
        * tests/subdir.test: Enable `errexit' shell flag, and related
        changes.  Use the `configure.in' stub created by `./defs',
        rather than writing one from scratch.
        * tests/subdir2.test: Likewise.
        * tests/subdir4.test: Likewise.
        * tests/subdir3.test: Enable `errexit' shell flag, and related
        changes.  Do not create useless dummy source files.
        * tests/subdir5.test: Make grepping of Makefile.in (in topdir
        and in subdirs) stricter.  Some minor changes to keep it more
        in sync with the related test `subdir8.test'.
        * tests/subdir8.test: Likewise (but with the related test being
        `subdir5.test' here).
        * tests/subdir6.test: Cosmetic change in spacing.
        * tests/subdir9.test: Define and use new variable `$distdir'.  Add
        trailing `:' command.
        * tests/subdir10.test: Cosmetic consistency-related change.
        * tests/subdirbuiltsources.test: Cosmetic changes in spacings.
        (configure.in): Use stub created by `./defs', rather than writing
        it from scratch.  Do not use obsoleted and/or deprecated forms of
        autoconf/automake macros.

        Modernize and improve test scripts `dist*.test'.
        * tests/distcleancheck.test: Do not add useless `-e' option to
        a $MAKE call.  Extend test by grepping stderr of make.
        * tests/distcom2.test: Do not run the same test script on the
        Makefile.in twice, but save its output in an intermediate file
        instead.  Make grepping of DIST_COMMON definition stricter.
        Display the content of more files, to ease debugging.  Add a
        trailing `:' command.  Improved heading comments w.r.t. sister
        test(s).
        * tests/distcom6.test: Likewise, and avoid to uselessly run
        autoconf.
        * tests/distcom3.test: Ensure verbose printing of captured stdout
        and stderr.  Make grepping of captured stderr stricter.  Also,
        add trailing `:' command.
        * tests/distcom4.test: Declare the target `test' in the generated
        Makefile.am as `.PHONY'.  Display content of more files, to ease
        debugging.  Add trailing `:' command.
        * tests/distcom5.test: Likewise.  Also, factor out common sed
        script in subroutine `extract_distcommon'.
        * tests/distcom7.test: Prefer cat + here-doc over echo to write
        test Makefile.am files.  Add a trailing `:' command.
        * tests/distname.test: Prefer `gzip -d' over `gunzip'.  Move the
        call to `set -e' earlier.  Be stricter and more verbose in the
        checking of the generated tarball.
        (configure.in): Use the stub provided by ./defs, instead of
        writing it from scratch.  Avoid obsoleted constructs.  Remove
        useless call to `AM_PROG_CC_C_O'.
        * tests/distdir.test: Various minor improvements/normalizations.
        * tests/distlinks.test: Likewise.

2010-07-18  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Improve and extend test cond5.test.
        * tests/cond5.test: Do not blindly sleep 60 seconds before polling
        the background automake process, but poll it every 10 seconds for
        at most 30 times (this makes the test both faster on good machines,
        and more resilient to spurious timeout-due failures when in low
        priority or on heavily-loaded systems).
        Check also that automake writes the expected error messages on the
        standard error.
        Enable `errexit' flag, and related changes.
        Rely on the `configure.in' stub created by `./defs', rather than
        writing one from scratch.

2010-06-26  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Update program --help output to match current GCS.

        is not defined, for compatibility to Autoconf < 2.64.
        * Makefile.am (do_subst): Substitute PACKAGE_BUGREPORT and
        PACKAGE_URL.
        (sc_diff_automake_in_automake): Update number of diff lines for
        additional substitutions.
        * aclocal.in (usage): Use PACKAGE_BUGREPORT.  Point to Automake
        home page and GNU general help page.
        * automake.in (usage): Likewise.
        * doc/automake.texi: New flag PACKAGE_BUGREPORT, to factor email
        address.
        (Introduction, Creating amhello, amhello Explained, Options):
        Use it throughout.
        * lib/Automake/Makefile.am (do_subst): Substitute
        PACKAGE_BUGREPORT.
        * lib/Automake/Config.in ($PACKAGE_BUGREPORT): New global.
        * lib/Automake/ChannelDefs.pm: Use it for footer of fatal
        messages.

        Clean up @var handling in the manual.
        * doc/automake.texi: Throughout the manual, lower-case @var
        names, replace a few one-character names.

2010-06-26  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Fix typo-related bug in test script silent5.test.
        * tests/silent5.test: Use $EGREP, not $GREP (which is not even
        defined).

        Tests: remove useless repetitions of `foreign' automake option.
        * tests/multlib.test (configure.in): Remove useless use of
        `foreign' option in AM_INIT_AUTOMAKE (the `--foreign' option is
        already in $AUTOMAKE by default, so no point in repeating it).
        * tests/subobj10.test: Likewise.
        * tests/subobj9.test: Likewise.
        * tests/lex3.test (Makefile.am): Similarly, remove useless use
        of `foreign' option in AUTOMAKE_OPTIONS.
        * tests/lex5.test: Likewise.
        * tests/pr279.test: Likewise.
        * tests/pr279-2.test: Likewise.
        * tests/specflg3.test: Likewise.
        * tests/target-cflags.test: Likewise.

        Drop useless requirement "gzip" in lex5.test.
        * tests/lex5.test ($required): Do not list "gzip", as it's
        never used.

2010-06-24  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Fix bugs in test script silent5.test.
        * tests/silent5.test: Fixed a nasty bug (due to the use of grep
        instead of egrep) that could have led to false negatives.

2010-06-21  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Add a test checking that distributed broken symlinks cause
        `make dist' to fail.

        Fix minor testsuite issues, update docs, for Yacc/Lex changes.
        * doc/automake.texi (Yacc and Lex): Mention AM_YFLAGS, YFLAGS
        and AM_LFLAGS, LFLAGS in the order in which they now appear in
        the rules.
        * NEWS: Update.
        * tests/lflags.test, tests/lflags2.test, tests/yflags.test,
        tests/yflags2.test: Prefer `make -e' over `make VAR=VAL', to
        please maintainer-check.  Ensure generated C files contain a
        declaration, to please compilers.

2010-06-21  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Fix bugs in Automake Yacc/Lex support w.r.t. $(AM_FLAGS) and
        $(FLAGS) precedence.
        * automake.in: Fix registration of languages "Lex", "Lex (C++)",
        "Yacc" and "Yacc (C++)", so that $(LFLAGS) has precedence over
        $(AM_LFLAGS) and $(YFLAGS) has precedence over $(AM_YFLAGS).
        * tests/Makefile.am (XFAIL_TESTS): Updated accordingly.
        * NEWS: Updated.

        New tests, exposing bugs in Automake Yacc/Lex support w.r.t.
        $(AM_FLAGS) and $(FLAGS) precedence.
        * tests/lflags.test: New test, check that user $(LFLAGS) takes
        precedence over automake (AM_LFLAGS) and (foo_LFLAGS).  Still
        xfailing.
        * tests/lflags2.test: Likewise.
        * tests/yflags.test: New test, check that user $(YFLAGS) takes
        precedence over automake (AM_YFLAGS) and (foo_YFLAGS).  Still
        xfailing.
        * tests/yflags2.test: Likewise.

        * tests/suffix5.test: Enable `errexit' shell flag, and related
        changes.  Make grepping of Makefile.in slightly stricter.
        * tests/suffix.test: Enable `errexit' shell flag, and related
        changes.  Also, do not redirect grep output to /dev/null, as this
        might unmotivatedly hide useful information.
        * tests/suffix2.test: Move setting of `errexit' shell flag earlier
        in the script (just after inclusion of ./defs).  Use a more
        idiomatic way to count text occurrences in Makefile.in with
        grep.  Do not create useless dummy source files.
        * tests/suffix10.test: Ensure verbose printing of captured make
        stdout.  Minor cosmetic changes.
        * tests/suffix8.test: Likewise.  Also, drop useless call to the

        $FGREP rather than plain grep.
        * tests/suffix11.test: Likewise.
        * tests/suffix12.test: Likewise.
        * tests/suffix9.test: Prefer cat + here-doc over echo to append to

        * tests/suffix13.test: Cosmetic spacing change.

2010-06-13  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Add useful comment in test script ext.test.
        * tests/ext.test: Add a comment explaining why an apparently
        useless `if' statement is indeed required.

2010-06-13  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Add useful comment in test script obsolete.test.
        * tests/obsolete.test: Add a comment explaining why we need
        an indirection in adding $AUTOUPDATE to $required.

        Normalize whitespaces in 'tests/Makefile.am'.
        * tests/Makefile.am (TESTS): Use only spaces, not tabs, in the
        definition of this variable.

        Parallel tests generation: improve comments (tiny change).
        * tests/Makefile.am ($(parallel_tests)): Added useful comment to
        generated tests.

        Tests defs: truly get rid of `$am_defs_included' (unused variable)
         * tests/defs.in ($am_defs_included): Remove, its now unused.  It
        should have been removed in a previous changeset, but the removal
        was done only partially (oversight).

2010-06-12  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Remove a couple of unneeded conditionals from tests.
        * tests/pr243.test, tests/pr266.test, tests/strip.test: No need
        for the FOOTEST conditional.

2010-06-12  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Modernize, improve and/or fix various test scripts.
        * tests/symlink3.test: Deleted, separated into two new, more
        complete tests ...
        * tests/forcemiss.test: ... this one ...
        * tests/forcemiss2.test: ... and this one.
        * tests/symlink2.test: Enable `errexit' shell flag, make test
        stricter, and skip it if symlink creation is not supported.
        * tests/postproc.test: Enable `errexit' shell flag, related
        changes, and a couple of unrelated cosmetic changes.
        * tests/recurs.test: Use the `configure.in' stub created by
        `./defs', rather than writing one from scratch.  Make grepping
        of Automake stderr slightly stricter.
        * tests/substtarg.test: Likewise.
        * tests/strip.test: Likewise, and move the call to `set -e'
        earlier (just after the inclusion of `./defs'). Also, make sure
        that the script installed by `make install-script' is equal to
        the original one.
        * tests/substref.test: Use the `configure.in' stub created by
        `./defs', rather than writing one from scratch.  Move the call
        to `set -e' earlier (just after the inclusion of `./defs').
        Avoid to explicitly export CC for configure (that's already done
        in ./defs).  Avoid potential problems with unpredictable make
        output.  Finally, make grepping of Makefile.in stricter.
        * tests/substre2.test: Ensure verbose printing of the captured
        make's output, and make its grepping slightly stricter.
        * tests/cygwin32.test: Enable `errexit' shell flag, and related
        changes.  Also, do not create useless dummy source/data files.
        * tests/scripts.test: Likewise.
        * tests/recurs2.test: Likewise.  Also, use the `configure.in'
        stub created by `./defs'.
        * tests/Makefile.am (TESTS): Updated.

        Modernize, improve and/or fix tests `pluseq*.test.
        * tests/pluseq5.test: Append to configure.in using cat with an
        here-doc, not using echo.
        * tests/pluseq10.test: Make sure that the captured output of
        `make' command is always displayed. Where possible, use $FGREP
        instead of grep (this change makes some checks slightly stricter).
        * tests/pluseq8.test: Enable `errexit' shell flag, with related
        changes.
        * tests/pluseq.test: Likewise.  Also, do not create useless dummy
        data files, and use better m4 quoting in generated configure.in.
        * tests/pluseq2.test: Likewise.  Also, append to configure.in
        using cat with an here-doc, not using echo.
        * tests/pluseq3.test: Likewise.
        * tests/pluseq4.test: Likewise.
        * tests/pluseq6.test: Likewise.
        * tests/pluseq7.test: Do not create useless dummy source file.

        * tests/cscope.test: Print captured stderr before failing.

2010-06-12  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Testsuite: ensure verbose printing of captured stderr.
        * tests/acloca18.test: Print captured stderr before either failing
        or grepping it.  Be sure to send captured stderr to stderr, not to
        stdout.
        * tests/ansi3b.test: Likewise.
        * tests/cond39.test: Likewise.

        * tests/missing4.test: Likewise, and fix a call to grep not to use
        the `-c' flag.
        * tests/ansi3.test: Likewise, and rely on the `configure.in' stub
        created by `./defs', rather than writing one from scratch.

        Enable `errexit' shell flag in various tests.
        * tests/backsl.test: Enable the `errexit' shell flag, and
        related changes.

        dummy source file.
        * tests/acoutpt2.test: Enable the `errexit' shell flag, and some

        * tests/ansi.test: Enable the `errexit' shell flag, and related
        changes.  Extended, esp. by running autoconf, ./configure and

2010-06-12  Stefano Lattarini  <stefano.lattarini@gmail.com>
            Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Extend tests/README w.r.t. trailing `:' in test scripts.
        * tests/README (section "Writing test cases" subsection "Do"):
        Explain why apparently redundant trailing `:' and `Exit 0' in
        test scripts can indeed be useful.

2010-06-11  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Improve determination of PATH separator in bootstrap script.
        * bootstrap: Determine what the PATH separator is the same way
        autoconf does.

        Minor improvements in bootstrap script.
        * bootstrap: Consistently use two-spaces indentation.  Cosmetic
        improvement to comments.
        ($me): New variable, containing program basename.
        Prepend it to all error messages.

        Testsuite now works with BSD make in parallel mode.
        * tests/defs.in: Unset variables __MKLVL__ and MAKE_JOBS_FIFO,
        which are exported by BSD make when run in parallel mode, and
        which can confuse make processes spawned by our testsuite.
        This change fixes a lot of spurious failure when the testsuite
        is run with BSD make in parallel mode.

2010-06-09  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Modernize, improve and/or fix various test scripts.
        * tests/sanity.test: Rely on the `configure.in' stub created by
        `./defs', rather than writing one from scratch.
        * tests/depend2.test: Likewise.  Also, call `set -e' just after
        the inclusion of `./defs', instead that later in the script.
        * tests/canon5.test: Avoid a useless `|| Exit 1' after a call to
        $AUTOMAKE, and improve the positioning of an $ACLOCAL call.
        * tests/exeext4.test: Use $FGREP instead of grep, where possible.
        Make auxiliary rules in the generated Makefile more silent.
        These changes make some checks slightly stricter.
        * tests/ext2.test: Call `Exit 1' if inclusion of `./defs' fails.
        * tests/gettext2.test: Place final `:' at the end of the script,
        rather than in the middle.
        * tests/exeext.test: Call `set -e' just after the inclusion of
        `./defs', instead that later in the script.
        * tests/extra5.test: Likewise.

        plain `mv', just to be sure.
        * tests/depcomp.test: Enable `errexit' shell flag, with related
        changes.  Also, modernize the generated configure.in.
        * tests/cond9.test: Likewise.  Also, rely on the `configure.in'
        stub created by `./defs', rather than writing one from scratch.
        * tests/cond10.test: Likewise.
        * tests/depcomp2.test: Likewise.
        * tests/depend3.test: Likewise.
        * tests/distcom7.test: Likewise.
        * tests/fortdep.test: Likewise.  Also, remove definition of
        AUTOMAKE_OPTIONS to `foreign' in the generated Makefile.am,
        since that flag is already provided by $AUTOMAKE.
        * tests/mdate.test: Made stricter, by checking that Automake
        actually failed, and by making a stricter grep on the error
        message.  Also, set shell `errexit flag'.
        * tests/python2.test: Improved verbose messages.

        Make test `ammissing.test' stricter.
        * tests/ammissing.test: Fail if $ACLOCAL succeeds unexpectedly.
        Enable `errexit' shell flag.

        Fix error in generation of parallel tests.
        * tests/defs.in ($am_skip_defs): New variable, to be used when
        ./defs must be sourced multiple times.  If set, unset it and
        only define $srcdir; otherwise, also go through the rest of
        the script.
        ($am_defs_included): Remove, no more needed.
        * tests/Makefile.am ($(parallel_tests)): Update accordingly,
        using only $srcdir from defs.
        Fixes potential test failures of tests that use $required.

        command substitution.
        * tests/unused.test: Likewise, and don't use an easily-avoided
        command substitution.
        * tests/version.test: Likewise, and avoid deprecated constructs

        Improve declaration of dependencies in the testsuite.
        * tests/Makefile.am (check_SCRIPTS): Remove.  Instead, let ...
        ($(TEST_LOGS)): ... all test logs depend on the scripts.
        * test/gen-parallel-tests: For each parallel test foo-p.test,
        let `foo-p.log' also depend on `foo.test', since it is sourced.

2010-06-06  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Prefer AUTOMAKE_fails over `$AUTOMAKE | grep' in tests.
        * tests/ldadd.test: Enable errexit.  Use AUTOMAKE_fails so
        the verbose log contains all output.
        * tests/mdate.test: Likewise.
        Prompted by Stefano Lattarini's change to discover.test.

2010-06-06  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        being different from the value at developer `make dist' time.
        * tests/defs.in: Protect against multiple inclusion, by using ...
        ($am_defs_included): ... this new variable.
        ($srcdir): Do not compute, but simply define to `@abs_srcdir@'
        as substituted by configure.
        Report, suggestions and first fix by Ralf Wildenhues, final
        patch by Stefano Lattarini.

        * tests/ext.test: Inside shell compound command, use
        `if $cmd; then Exit 1; fi' rather than `$cmd && Exit 1', to

2010-06-06  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Tiny fix in silent8.test (display output of `make' command).
        * tests/silent8.test: Make sure that the captured output of `make'
        command is always displayed.

        Make tests on user extensibility of silent-rules mode stricter.
        * tests/silent6.test: Made stricter w.r.t. the grepping of the
        output produced by `make'.

        command to keep it better in sync with tests/silent{4,9}.test.

        Improved test silent5.test.
        * tests/silent5.test: Remove by hand all generated C files after
        non-verbose builds, to ensure the following builds are clean.
        Try to clean and rebuild with the same verbosity and without
        removing generated sources in between, to check that this does
        not trigger a different set of rules.  Make grepping of make's
        output stricter.  Improved/added some comments.

        New tests for Automake silent-mode with Fortran.

        Relax tests on silent-rules to cater to overly verbose makes.
        * tests/silent.test: When testing silent builds, don't fail if
        make's output simply contains the `mv' substring, but only if
        it contains the `mv ' substring (note the trailing space).

        Extend test on `nostdinc' automake option.
        * tests/nostdinc.test: Enable `errexit' shell flag.  Related and
        unrelated minor changes.  Make the grepping of the generated
        Makefile.in slightly stricter.  Generate and run configure, so that
        the generated Makefile can be grepped too.

2010-05-23  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Make gnupload portable to EBCDIC hosts.

2010-05-23  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Fix Autoconf version required by Automake's configure.
        Automake configure script used to tell that automake required
        autoconf 2.60 or later, but then it checked for autoconf >= 2.62,
        and if that was not found, it gave an error saying that Automake
        required configure 2.61a-341 or later.  This change should
        eliminate such inconsistencies.
        * configure.ac ($required_autoconf_version): New variable.
        Use it throughout.

2010-05-23  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        * Makefile.am (sc_tests_Exit_not_exit): Rewrite sed script to
        not contain semicolon after 'b' or brace commands, for NetBSD.

        Wildcards are not portable to NetBSD make.
        * doc/automake.texi (Wildcards): Document portability issue.
        * tests/extra10.test, tests/extra11.test, tests/extra12.test:
        Require GNU make.

2010-05-23  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Make test for configure.in vs. configure.ac stricter.
        * tests/configure.test: Use a configure.in file that provokes
        an automake error, to ensure configure.ac is preferred.

        Avoid possible false negatives in dejagnu7.test.
        * tests/dejagnu7.test: Enable shell `errexit' flag.  Also, avoid
        unportable use of fgrep option `-e'.

        Fix conflnk3.test to work with Solaris/Heirloom Sh.
        * tests/conflnk3.test: Use `test -r FILE' and `test ! -r FILE'
        instead of respectively `test -e FILE' and `test ! -e FILE',
        since Solaris Sh doesn't grok the latter.  Do not SKIP the test
        if the shell doesn't support `test -e'.

2010-04-25  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Warning and error message formatting cleanups.
        * aclocal.in (parse_arguments, main): Remove trailing period or
        newline in error or warning messages, avoid capitalization of
        the first word of a message.

        * tests/ltinstloc.test, tests/suffix11.test: Adjust expected
        error message.
        * lib/Automake/Channels.pm (setup_channel): Reword error message
        to be the same as in msg.

        * aclocal.in (usage): Likewise.  Also, fix indentation.

        Fix more duplicate message prefixes.
        * lib/Automake/XFile.pm (seek): Do not prepend $me.
        ($me): Remove now-unused package-global.
        * aclocal.in (check_acinclude): Remove duplicate 'warning: '
        prefix.

        Fix typo in manual.
        * doc/automake.texi (Simple Tests using parallel-tests): Add
        missing closing parenthesis.

        Fix leftover call to removed function macros_dump.
        * automake.in (read_main_am_file): Call variables_dump, not
        macros_dump.  Print actual error before list of variables.

2010-04-22  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Minor improvements in comments of test `silent3.test'.
        * tests/silent3.test: Tell to keep it in sync with `silent9.test'
        too.

2010-04-25  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        testsuite: ensure verbose printing of captured output.
        * tests/acloca14.test, tests/acloca18.test, tests/aclocal.test,
        tests/fort2.test, tests/help.test, tests/missing3.test,
        tests/missing6.test: Print captured stdout or stderr before
        grepping it.

2010-04-20  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Make test badopt.test stricter (by enabling `set -e').
        * tests/badopt.test: Add call to `set -e'.  Due to this change,
        an unexpected failure in the call to `$ACLOCAL' (whose outcome
        was previously unchecked) would cause the whole test to fail.
        Also, bumped the copyright years.

        Make test for configure.in vs. configure.ac stricter.
        * tests/configure.test: Use a configure.in file that provokes
        an automake error, to ensure configure.ac is preferred.

        Use `set -e' in confsub.test (avoids possible false negatives).
        * tests/confsub.test: Enable shell `errexit' flag, and related
        changes (this helps avoiding some possible minor false negatives).
        Also, bumped copyright years.

2010-04-20  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Fix -Werror handling for presence of configure.in and configure.ac.
        * lib/Automake/Variable.pm (Automake::Variable): Do not initialize
        $configure_ac at the global level, before command-line arguments
        have been parsed.
        (require_variables): Initialize it here.
        * tests/configure.test: New test.
        * tests/Makefile.am: Update.
        Report by Stefano Lattarini.

2010-04-20  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Avoid possible false negatives in confh5.test.
        * tests/confh5.test: Enable shell `errexit' flag, and bumped
        copyright years.  Due to this change, any unexpected failure
        in calls to $ACLOCAL, $AUTOMAKE, $AUTOCONF or $AUTOHEADER, or
        a failure in grepping expected text in output files should now
        cause the whole test to fail.

2010-04-17  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Fixed typo in POD documentation of Automake::Channels.
        * lib/Automake/Channels.pm: Fixed typo in POD documentation:
        @<...> was used instead of C<...>.

2010-04-14  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Refactor tests on Automake TESTS color output.
        * tests/color.test: Tests using the expect program moved out to...
        * tests/color2.test: ... this new file.
        * tests/Makefile.am (TESTS): Extended accordingly.

2010-04-12  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Fix typos in comments in test confh5.test
        * tests/confh5.test: Fix a couple of typos in comments.

        Avoid possible false negatives in canon-name.test.
        * tests/canon-name.test: Enable shell `errexit' flag.  Improve
        test description.

2010-04-11  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Print 'warnings are treated as errors' note if needed.
        * lib/Automake/Channels.pm: Fix typo in comment.
        (_print_message): If -Werror is enabled, print a 'warnings are
        treated as errors' note before the first such warning.
        * tests/warnopts.test: Adjust comment to mention expected warning.
        Adjust code to ignore 'warnings are treated as errors' note.
        * tests/location.test: Adjust expected output with -Werror.
        * tests/werror4.test: New test.
        * tests/Makefile.am: Update.
        * NEWS: Update.

        Ensure we don't print 'warning:' or 'error:' twice.
        * Makefile.am (sc_ensure_testsuite_has_run): New helper rule.
        (sc_tests_logs_duplicate_prefixes): New rule, to check for
        wrong-looking warning and error messages in the test suite logs.
        * aclocal.in (scan_configure_dep, scan_file): Remove duplicate
        `warning: ' prefix.
        * tests/vars3.test: Rename variable to avoid false positive.

        Prepend type to warning, error, and fatal messages.
        For the first part of messages of types `error' or `fatal',
        prepend `error: ' to the message.  Prepend `warning: ' to
        warning messages, whatever the setting of -Werror.
        * lib/Automake/Channels.pm (partial): Move up definition.
        (_format_message): Emit `header' and `footer' strings only with
        the first resp. last part of a set of partial messages.
        * lib/Automake/ChannelDefs.pm: Add missing '1;' statement at the
        end of the module.
        (Automake::ChannelDefs): Setup warning channels with header
        `warning: ', error and fatal messages with header `error: '.
        * tests/condinc2.test, tests/ltinstloc.test: Adjust expected
        error messages.
        * tests/comment5.test: Likewise.  Also, include stack notes
        should not start with `error:'.
        * tests/location.test: Likewise.  Also, try both -Werror and
        -Wno-error.
        * NEWS: Update.
        Report by Bruno Haible.

        Fix capitalization of error messages, reword one message.
        * lib/Automake/Variable.pm (define): Do not capitalize the first
        word in the error message.
        * automake.in (require_file_internal): Likewise.  Also, reword
        and line-wrap for better readability.
        * tests/distcom7.test, tests/pluseq5.test, tests/pluseq9.test:
        Adjust tests.

        Fix connected warnings about obsolete exeext override.
        * lib/Automake/Rule.pm (define): Merge two warnings that belong
        together, by setting the 'partial' flag for the first one.

        Fix per-Makefile.am setting of -Werror.
        Before this patch, 'AUTOMAKE_OPTIONS = -Werror' in one
        Makefile.am would carry over to other Makefile.am files
        treated afterwards by the same thread, causing inconsistent
        and unstable exit status values.
        * lib/Automake/Channels.pm (dup_channel_setup)
        (drop_channel_setup): Save and restore the setting of
        $warnings_are_errors.
        * tests/werror3.test: New test.
        * tests/Makefile.am: Adjust.
        * NEWS: Update.

2010-04-11  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Bugfix in confh5.test w.r.t. Solaris/Heirloom Sh.
        * tests/confh5.test: In the generated Makefile.am: do not use
        `test ! -e FILE' to check for the non-existence of a file, since
        that is not supported by Solaris/Heirloom Sh.

        Make test `aclocal3.test' stricter.
        * tests/aclocal3.test: Add call to `set -e'.  Fail if $ACLOCAL
        succeeds unexpectedly.

        Add tests checking that symlinks are resolved by `make dist'.
        * tests/distlinks.test: New test.
        * tests/Makefile.am (TESTS): Updated accordingly.
        Suggested by observations from Ralf Wildenhues.

2010-04-11  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Use -9 for maximum xz compression with dist-xz.
        * lib/am/distdir.am (dist-xz, dist, dist-all): Pass -9 to xz.
        * NEWS, THANKS: Update.
        Report by Pavel Sanda.

2010-04-11  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Avoid possible false negatives in cond46.test.
        * tests/cond46.test: Enable shell `errexit' flag (and bumped
        copyright years).  Due to this change, the testcase should now
        fail on unexpected failures in calls to $ACLOCAL/$AUTOMAKE (whose
        outcomes were previously unchecked), and on failures in grepping
        the expected diagnostic in Automake stderr.

2010-04-04  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Generated tests are now just a thin layer around other tests.
        * tests/Makefile.am: Rewrite the rule to generate the `*-p.test'
        test scripts so that any of them simply includes the corresponding
        `*.test' script (after setting `$parallel_tests' to `yes').
        * tests/.gitignore: Add wildcard for temporary files used in the
        generation of `*-p.test' tests.

2010-03-30  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Avoid an unportable use of `$status' shell variable.
        * Makefile.am (path-check): Don't use the `$status' shell variable
        in the target's rules, as it's special in Zsh (equivalent to `$?',
        and readonly).

        Avoid another use of `chmod -R'.
        * Makefile.am (path-check): To be safe, do not use `chmod -R' on
        $(distdir) before removing it (as Solaris `chmod -R' touches
        symlink targets).  Instead, use the cleanup strategy used in
        distdir.am.

2010-03-28  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Remove uses of @acronym and @sc.
        * doc/automake.texi (Public Macros, Limitations on File Names):
        Remove all usage of @acronym and @sc in the manual.
        Suggested by Karl Berry.

2010-03-13  Karl Berry  <karl@freefriends.org>

        GNU hello uses fdl.texi, not gpl.texi.
        * doc/automake.texi (Texinfo): Adjust example to upstream
        change.

2010-03-06  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Formatting cleanups in macro comments.
        * automake.in, lib/Automake/Channels.pm,
        lib/Automake/FileUtils.pm, lib/Automake/Options.pm,
        lib/Automake/Variable.pm, lib/Automake/XFile.pm,
        m4/options.m4, m4/substnot.m4: Fix macro comment format.

2010-03-04  Stefano Lattarini  <stefano.lattarini@gmail.com>
            Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Avoid generation of `tests/defs-p' file.
        * tests/defs.in: In the generated `configure.in' snippet: call
        `AM_INIT_AUTOMAKE' with the `parallel-tests' option if the shell
        variable `parallel_tests' is set to `yes'.
        * tests/Makefile.am (defs-p): Target removed.
        (check_SCRIPTS): Removed `defs-p'.
        (clean-local-check): Do not unlink `defs-p' anymore.
        ($(parallel_tests)): Transformation rules for the test scripts
        adjusted.
        * tests/gen-parallel-tests: Selection rules for the test
        scripts adjusted.
        * tests/parallel-tests.test: Set `$parallel_tests' to `yes'

        Fix exit status of signal handlers in shell scripts.

        %VERBOSE-NODEP%.
        * automake.in (verbose_nodep_flag): New function, appending
        `@am__nodep@' to the verbose-variable name.
