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 + (an hope we'll take such a step eventually). + + * t/cond29.sh: Move ... + * t/perf/cond.sh: ... here, and adjust. + * t/testsuite-recheck-speed.sh: Move ... + * t/perf/testsuite-recheck.sh: ... here. + * t/testsuite-summary-speed.sh: Move ... + * t/perf/testsuite-summary.sh: ... here. + * t/list-of-tests.mk (perf_TESTS): New variable, listing the tests in + the 't/perf' directory. + (handwritten_TESTS): Adjust. + * defs: Skip any tests in the 't/perf/' subdirectory unless the + 'AM_TESTSUITE_PERF' variable is set to "yes" or "y". + * .gitignore: Update. + +2012-05-29 Stefano Lattarini <stefano.lattarini@gmail.com> + + Merge branch 'fix-pr11543' into maint + + * fix-pr11543: + aclocal: declare function prototypes, do not use '&' in function calls + +2012-05-29 Stefano Lattarini <stefano.lattarini@gmail.com> + + aclocal: declare function prototypes, do not use '&' in function calls + + This change will also fix automake bug#11543 (from a report by Matt + Burgess). + + * aclocal.in: Declare prototypes for almost all functions early, before + any actual function definition (but omit the prototype for the dynamically + generated '&search' function).

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).

Later, the msvc branch was merged + directly into branch-1.11, in order to rush the new features to the + market and to keep the released scripts (lib/ar-lib, lib/compile and + lib/depcomp) consistent with those on the master branch. However, + some changes had to be made to the features added by the msvc branch + in order for them to fit the requirements of branch-1.11, notably that + the warnings issued in the extra-portability class cannot be enabled + by -Wall in the 1.11.x maintenance releases. + + In retrospect, it would have been better to not merge msvc directly + into branch-1.11, but instead do it via the maint branch (followed up + with a dummy merge from maint into master) the moment it was decided + that the msvc changes should make it into branch-1.11. + + All in all, this merge is going to affect neither the master branch + nor branch-1.11, since it is followed up with dummy merges masking all + changes.

This had the annoying side effect of + requiring that, whenever a non-default make program was to be used + in the test cases, that same make program had to be used to drive + the execution of the automake testsuite; otherwise, the recursive + make invocations could pick up $MAKE from the environment, and use + that instead of re-executing with the correct make. + + So, for example, if one wanted to try how Solaris /usr/ccs/bin/make + behaved in the automake test cases, he couldn't run the testsuite + in parallel mode, because that make lacks support for concurrent + execution of recipes; on fast machines, this easily meant a 4x or + higher slow-down. + + Once the problem is clear, the solution is pretty simple: allow + the use of another variable, besides $MAKE, to override the make + program to be used in the test cases. + + See also commit `v1.11-1318-g3ceeef4', that introduced a more + general version of this change to the master branch. + + * tests/defs.in: Allow the make implementation to be used by the + test cases to be overridden by the `$AM_TESTSUITE_MAKE' variable, + in preference to the `$MAKE' variable. + +2011-12-30 Stefano Lattarini <stefano.lattarini@gmail.com> + + docs: fix a couple broken anchors + + * doc/automake.texi: In previous commit v1.11-605-g5f71f2b (related + to automake bug#8071), we had renamed the chapters about aclocal + and automake invocation, and added anchors to the old names as not + to break hyperlinks to our on-line manual.
