+
+       docs: how to use '-I' option in AM_CPPFLAGS for best VPATH support
+       * doc/automake.texi (Program Variables): Recommend -I options to
+       both the build directory and the source directory when needed.
+
+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.

+
+       test defs: function 'is_newest' now works also with directories
+       * tests/defs (is_newest): Call `find' with the `-prune' option,
+       so that it won't descend in the directories (which could cause
+       spurious results).
+       * tests/self-check-is_newest: Extend accordingly.
+       From a report by Jim Meyering, see automake bug#9147.

+       tests: fix typos, grammaros and other blunders in comments

+
+       tests: more uses of the 'unindent' subroutine

+       * tests/autodist.test: Do not whitespace-indent `##' comments when

+       make.

+       compiled `.elc' files get installed by "make install", and
+       uninstalled by "make uninstall".
+       * tests/lisp4.test: Ensure installed `.el' files gets removed by

+       content of xfailing test `baz.test' with a "weaker" version that
+       fails unconditionally: the test must fail only when the 'strict'
+       pragma is in use, in order not to reduce coverage.

+
+       tests: portability fixes in tests on amhello examples
+       * tests/amhello-binpkg.test: Don't use "tar xzf too.tag.gz" to

+
+       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
+       ksh-derived shells" in GNU coreutils.

+       variable `$test_prefer_config_shell' has become an internal

+       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

+       the `errexit' flag.  Remove an unnecessary `|| Exit 1' guard.

        test defs: new function 'fatal_', for hard errors
        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.in (fatal_): New function.
+       * 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.

+
+       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

+
+2011-06-07  Stefano Lattarini  <stefano.lattarini@gmail.com>
+
+       tests: can use also $SHELL to check shell scripts from `lib/'

+       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

+       (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

+
+       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.

+       of the make output.  Work around this by using a wrapper script

+       tests: fix spurious failures in self tests
+       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 bug introduced by commit 'v1.11-874-g1321be7'.
+       * tests/defs: Only check that we can find the client test script
+       when we must re-execute it.
+       * tests/self-check-cleanup.test: Export `AM_TESTS_REEXEC' to "no"
+       before running the self tests.

+
+       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
+       the generic "Simple Tests" driver.
+       * tests/gen-parallel-tests: Update, mostly to reflect the new
+       `.ptest' extensions used for tests in $(parallel_tests).
+       * Makefile.am (TESTS_EXTENSIONS): Add `.ptest'.
+       (PTEST_LOG_COMPILER): Define, it calls `parallel-tests.sh'.
+       ($(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.
+       (EXTRA_DIST): Distribute `parallel-tests.sh'.
+       (MAINTAINERCLEANFILES): Don't remove the `$(parallel_tests)', it
+       is not necessary anymore.
+       (generated_tests): Variable definition removed.
+       (TESTS): Update, by listing `$(parallel_tests)' directly instead
+       of `$(generated_tests)'
+       (expected_list_of_tests): Remove `$(generated_tests)'.
+       (maintainer-check-list-of-tests): No need to explicitly depend on

+       coverage in case of cross-compiling, when GCC can be named e.g.,

+       Export `CC' to the overridden value only once.

+       The "avoid the requirement of a working compiler" we refer about

+       defining `CC' (and `EXEEXT', `OBJEXT', `CXX', etc., if needed) to
+       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

+       Other minor cosmetic changes.  Use a `timeout' program (if it's
+       available) to determine whether the script takes too long, instead
+       of just hoping that the user will notice an abnormally long test
+       execution time.
+       * tests/cond33.test: Extend a bit.  Fix heading comments.  Few more

+
+       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.
+       * tests/lex3.test: Likewise.

+
+       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.

+
+       testsuite: user can force skipping of compiler-requiring tests

+       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.

+
+       test defs: increase coverage w.r.t. GNU make
+       * tests/defs (GNUmake): Instead of just skipping the tests
+       requiring GNU make if $MAKE is not GNU make, try to look for
+       it and, if found, redefine $MAKE accordingly.  This will help

        tests: fix spurious failure in 'color2.test'
        * tests/color2.test: If $MAKE contains command-line arguments (as
        in e.g., "make -j2"), expect's directive "spawn $env(MAKE)" fails
        spuriously, because it tries to run "$MAKE" as a single command.
        Fix this with proper uses of the TCL `eval' builtin.

+       * tests/remake1a.test: Likewise.

+2011-05-01  Stefano Lattarini  <stefano.lattarini@gmail.com>
+
+       tests: extend tests on dependency tracking with VPATH
+       * tests/depmod-tests.sh: New script, fulfilling a threefold role:
+       1. it is called to generate a Makefile.am snippet, containing the
+          definition of proper lists of tests;
+       2. it is called to set up a directory containing some common data
+          files and autotools-generated files used by the aforementioned
+          tests (this is done for speed reasons only); and
+       3. it is called to properly run those tests, one at a time.
+       * tests/depcomp9.test: Delete, it's obsolete now.
+       * tests/depcomp10.test: Likewise.
+       * tests/Makefile.am ($(srcdir)/depmod-tests.am): Include this

+       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 $(depmod_tests).
+       (EXTRA_DIST): Distribute depmod-tests.sh.
+       Other minor cosmetic changes and reorderings.
+       * bootstrap: Generate depmod-tests.am.
+       * tests/.gitignore: Updated.
+
+2011-05-01  Stefano Lattarini  <stefano.lattarini@gmail.com>
+
+       tests: avoid extra test generation (for `instspc' tests)
+       We don't really need to generate tons and tons of wrapper test
+       scripts (presently, ~ 90) just to run what is basically a single
+       test (specifically, `instspc-tests.sh') with different parameters.
+       In fact, the possibility of running a single driver script with
+       multiple files/configurations/parameters is one of the major
+       selling points of the 'parallel-tests' testsuite driver of
+       automake.  So why not use ourselves more extensively the best
+       features we provide?
+       * tests/instspc-tests.sh: Update heading comments.  Expect
+       to be executed, not sourced.  Update handling of command-line
+       arguments.  Adjust to reflect the renaming of "instspc tests"
+       from `instspc-*.test' to `*.instspc'.
+       * tests/instspc-data.test: Update heading comments.  Execute
+       driver script `instspc-tests.sh', instead of sourcing it.
+       Give more informative messages in case of internal errors.
+       * tests/Makefile.am (TESTS_EXTENSIONS): Define explicitly (to
+       `.test' and `.instspc').
+       (TESTS): Add `$(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.

+       (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: add sanity check to 'self-check-cleanup.test'

+       `defs-static' used by the test differs from the "vanilla" one
+       in builddir.  This also offers a little more debugging output.

+       export it.
+       * tests/self-check-report.test: Prevent new spurious failures by
