maint: deprecate 'configure.in' as autoconf input

It has been years since that has been deprecated in the documentation,
in favour of 'configure.ac':

    Previous versions of Autoconf promoted the name configure.in, which
    is somewhat ambiguous (the tool needed to process this file is not
    described by its extension), and introduces a slight confusion with
    config.h.in and so on (for which '.in' means "to be processed by
    configure"). Using configure.ac is now preferred.

It's now time to start giving runtime warning about the use of
'configure.in', so that support for it can be removed in future
versions of autoconf/automake.

perf: beginning of a performance testsuite

Some tests in the Automake testsuite already aims only at verifying
the performance, rather than the correctness, of some operations.
Still, they are somewhat shoehorned and forced into the PASS/FAIL
framework (say, with the 'ulimit' shell builtin used to verify some
operation doesn't take up too much time or memory), but that is
conceptually a stretch, and has already caused problems in practice
(see automake bug#11512 for an example).

So we start moving the "performance tests" out of the testsuite proper,
and make them run only "on demand" (when the user exports the variable
'AM_TESTSUITE_PERF' to "yes").  Ideally, we should provide those tests
with a custom runner/driver that measures and displays the relevant
performance information, but doing that correctly and with the right
APIs is definitely more difficult, so we leave it for a later step

If Automake is used in non-recursive mode and one of the inputs is a
yacc file, for example, "src/grammar.y", ylwrap will remove too many
directories from the output file when it adjusts the paths in it.
This results in #line directives referring to "grammar.y" instead of
"src/grammar.y".

This is a result of $input_rx simply taking all the directory
components of the absolute input path and removing them.

One solution is to store the path passed to ylwrap and replace
$input_rx with it.  This is what we do.

tests: use append mode to capture parallel make output

This should fix the spurious failure reported in automake bug#11413.

This is due to the fact that the redirected output of parallel make
can racily loose lines.  For example, if GNU make (3.82) is run on
a Makefile like this:

  all = 0 1 2 3 4 5 6 7 8 9
  default: $(all)
  $(all):
        @sleep 0.$$(($RANDOM % 10)); echo $@

and has its standard output redirected in overwrite-mode to a regular
file, it looses a line of that output every 15 runs or so on a Fedora
17 system with 64 ppc64 cores and Linux 3.3.1.  Redirection in append
mode does not suffer of this problem.

See also similar commit 'Release-1-10-280-g6426999' of 2009-03-10,
"Use append mode to capture parallel test output", which tackled a
similar problem for 't/parallel-tests3.sh' and 't/lisp8.sh'.

* t/tap-more.sh: Use append mode for output from "make -j", to avoid

color-tests: coloring can be forced on non-ANSI terminals as well

Before this change, colorization of testsuite output was suppressed
whenever the terminal was recognized to be a "dumb" one, incapable
of handling ANSI coloring (i.e., when the environment variable TERM
had a value of "dumb").  This happened even when the AM_COLOR_TESTS
variable was set to a value of "always".

Such a behaviour was suboptimal and slightly confusing; in fact, if
a user wants to force coloring of testsuite output that is being
redirected to a regular file, he should be able to do so even if his
terminal is not capable of handling ANSI colors -- in fact, such
terminal wouldn't be involved with the testsuite output in any way,
so why should it be allowed to influence it?

Thus, we now enable coloring of test output whenever AM_COLOR_TESTS
is set to "always", irrespective of the value of the TERM environment
variable.

target (as it is a dependency of the 'distdir' target), and thus ends up
re-bootstrapping all the package (because of the .PHONY 'bootstrap' target
in GNUmakefile).

We fix this issue by renaming our bootstrap script to 'bootstrap.sh'.

* bootstrap: Renamed ...
* bootstrap.sh: ... to this.
* GNUmakefile (bootstrap): Adjust.

build: ensure release year in copyright notice is up-to-date

From a suggestion by Eric Blake.  See automake bug#11356.
This is a follow-up to previous patch 'v1.12-12-gb99b5be'.

* configure.ac (RELEASE_YEAR): New AC_SUBST'd variable, should hold
the value of the current year.
* Makefile.am (update-copyright): Be sure to also update the
definition of 'RELEASE_YEAR' in configure.ac.
* lib/Automake/Config.in ($RELEASE_YEAR): New exported variable,
initialized from the value substituted for '@RELEASE_YEAR@'.
(@EXPORT): Add it.
* automake.in, aclocal.in: Use '$RELEASE_YEAR' (which will be
substituted at make time) instead of hard-coding the release
year.  This should ensure the copyright range in the version
message and in the generated files (Makefile.in and aclocal.m4)
are automatically kept up-to-date.
* bootstrap (dosubst): Update, also substitute '@RELEASE_YEAR@'.

12 years agobootstrap: add convenience make target
Stefano Lattarini [Fri, 27 Apr 2012 16:48:27 +0000 (18:48 +0200)]
bootstrap: add convenience make target

Dependencies in the Automake build system are not completely specified
(see for example the commit log of recent commit 'v1.12-10-gab14841',
"build: avoid too greedy rebuilds in the testsuite").  In fact, some of
them cannot even be; for example, Makefile is generated at configure
time from Makefile.in, which should be regenerated by our bleeding-edge
automake script, which is generated by out Makefile -- specifying the
complete chain of dependencies here would bring to a circular dependency
issue.

For this reason, before testing or deploying a change, we are often
forced to perform a full re-bootstrap of the Automake package, to ensure
all our files are actually up-to-date.  Until now, this has to be done
manually, thus causing wasted keystrokes and more possibilities of error.

With this change, we introduce a new 'bootstrap' make target to
automatize all the (easy) steps of this re-bootstrapping (plus some
minor bells & whistles since we are at it).

* GNUmakefile: Rewrite to allow an easy bootstrapping and clean rebuild
of the whole package, in particular with the help of ...
(bootstrap): ...  this new target.

Stefano Lattarini [Thu, 26 Apr 2012 13:05:05 +0000 (15:05 +0200)]
build: avoid too greedy rebuilds in the testsuite

The autogenerated makefile fragment 't/testsuite-part.am' used to depend
on the list of *all* the hand-written files.  This was technically correct,
since that makefile fragment was (and still is) generated by the script
'gen-testsuite-part', which scans all the hand-written files to detect
implicit dependencies and to decide for which tests a further wrapper test
should be generated.

However, the presence of such a dependency implied that, whenever *any*
test case was modified (no matter how slightly), the 't/testsuite-part.am'
file was rebuilt, and since that is included by our 'Makefile.am', the
'Makefile.in' file was rebuilt as well by automake.  In order to do so,
automake scanned our 'configure.ac' file, which requires the latest
Autoconf version (2.69 at the time of writing), and the casual user can
easily lack that on his machine (and that should be allowed, as automake
currently supports any autoconf version >= 2.62).

The described situation could hinder in-field testing or debugging by
users (even experienced ones) that are not automake developers; see for
example automake bug#11347.

So we drop the explicit dependency of 't/testsuite-part.am' on the
hand-written test cases.  (As an aside, note that this has already
been done in Automake-NG, albeit for other reasons; see the commit
'v1.11b-129-g1690aca' of 2012-04-23, "[ng] build: define $(TESTS)
through a wildcard").

This is not a serious regression in the faithfulness of the Automake
build systems, since it unfortunately already had several undeclared
dependencies; e.g., 'Makefile.in' should depend on the automake script,
and 'aclocal.m4' should depend on the aclocal script (but this isn't
possible, as it would mean that distributed files depend on ones generated
at make time).  Similarly, 'Makefile.in' should depend on some of the
'lib/am/*.am' files, but does not.

Currently, the workaround to get a faithful and correct rebuild is to run

  ./bootstrap && ./config.status --recheck && make clean all

and the present commit does not change that.

* Makefile.am ($(srcdir)/t/testsuite-part.am): Don't depend on
't/list-of-tests.mk' nor on '$(handwritten_TESTS)' anymore.
($(generated_TESTS)): Likewise, and don't depend on 'Makefile.am'
either.
