Stefano Lattarini 34001a98 2013-01-09T23:16:53 compile: use 'compile' script when "-c -o" is used with losing compilers Do so seen when only source files in the "current" directory are present. This commit is part of a series of related changes addressing automake bug#13378 (see also the plan 'PLANS/subdir-objects.txt'). Before this change, Automake-generated C compilation rules mistakenly passed the "-c -o" options combination unconditionally (even to losing compiler) when the 'subdir-objects' was used but sources were only present in the top-level directory. Issue spotted by Nick Bowler: <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=13378#35> <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=13378#44> We fix this by having Automake redefine AC_PROG_CC to take over the role of AM_PROG_CC_C_O and to require the 'compile' script unconditionally (albeit that will continue to be invoked only when inferior compilers are detected). Among other things, this means AM_PROG_CC_C_O explicitly is no longer required; that macro is still supported for backward-compatibility, but calling it is basically a no-op now. This change has some pros and some cons (obviously, we believe the former outweighs the latter). Here are the most relevant ones: + Pros 1: Some logic in the Automake script has been simplified. + Pros 2: That simplification has automatically fixed an actual bug (see Nick's mails referenced above; admittedly, that was present only in corner-case situations, but still); the test 't/ccnoco4.sh', which demonstrated the bug and has been failing so far, now passes. + Pros 3: Things works more "automagically" now (no need to manually add the AM_PROG_CC_C_O macro to configure.ac anymore). * Cons 1: The 'compile' script will be required in all projects using C compilation; this will only be a problem for packages not using '--add-missing'. However, such packages are definitely more rare than the ones using '--add-missing', and adjusting them will be trivial -- just copy the compile script over from the new Automake installation. * Cons 2: The copy & paste of autoconf internals hack this change has introduced in our "rewrite" of AC_PROG_CC is really an egregious abomination. It can only be justified with the fact that we expect future versions of autoconf to implement the semantics we need directly in AC_PROG_CC, so that we'll be able to leverage that (since Automake 1.14 will require the latest Autoconf version released). Now, the detailed list of file-by-file changes ... * automake.in ($seen_cc_c_o): Remove this global variable. (scan_autoconf_traces): Don't set it, and do not trace the 'AM_PROG_CC_C_O' m4 macro. (lang_c_rewrite): Remove, no longer needed. * doc/automake.texi: Adjust expected "autoreconf --install" output in the amhello example. Remove statements about the need for the AM_PROG_CC_C_O macro. Report it is obsolete now. * m4/init.m4: Re-write AC_PROG_CC to append checks about whether the C compiler supports "-c -o" together. These checks have basically been ripped out (with adaptations) from the 'AC_PROG_CC_C_O' macro of Autoconf and ... * m4/minuso.m4 (AM_PROG_CC_C_O): ... this macro of ours, which has thus basically become a no-op. * t/ax/am-test-lib.sh (am_setup_testdir): Also copy the 'compile' script in the test directory; if we don't do so, every test using AC_PROG_CC should call automake with the "--add-missing" option, or copy the 'compile' script itself. * t/cond11.sh: No need to create a dummy 'compile' script: that is already brought in by 'am_setup_testdir()', that is automatically invoked when 'test-lib.sh' is sourced. * t/add-missing.tap: Adjust: we expect the 'compile' script to be required by a mere AC_PROG_CC call now. * t/dist-auxdir-many-subdirs.sh: Likewise. * t/specflg6.sh: Likewise. * t/subobj4.sh: Likewise. * t/cxx-lt-demo.sh: Likewise, and update comments to match. * t/distcom2.sh: Enhance a little. * t/dollarvar2.sh: Adjust. * t/extra-portability.sh: Likewise. * t/libobj19.sh: Likewise. * t/per-target-flags.sh: Likewise. * t/repeated-options.sh: Likewise. * t/subobj.sh: Likewise, and enhance a little. * t/ccnoco2.sh: Remove as obsolete. * t/list-of-tests.mk (handwritten_TESTS): Adjust.

Stefano Lattarini 5ddf1007 2012-10-27T16:41:39 tests: prefer including 'test-init.sh' rather than './defs' This is a follow-up to today's commit v1.12.4-22-g0610fc8, "tests: prepare to move ./defs to t/ax/test-init.sh" * All tests: To run the common setup, use the command: . test-init.sh instead of the older, "historical" one: . ./defs || exit 1 Note that the "|| exit 1" wasn't really useful, since the 'errexit' shell flag is in effect in both './defs' and 'test-init.sh', and all the known shells that are good enough to run the automake testsuite do automatically exit with error when a sourced file cannot be found (at least, they do so in non-interactive mode, which is the only mode that concerns us in the testsuite). * t/ax/tap-summary-aux.sh, t/ax/testsuite-summary-checks.sh: Likewise. * gen-testsuite-part: Do the same in the generated tests.

Jack Kelly 226be35f 2012-07-14T21:52:43 elisp: use suffix rules, get rid of 'elisp-comp' script (mostly a rewrite) Motivated by automake bug#11806. Traditionally, automake byte-compiled emacs-lisp '.el' files by invoking 'elisp-comp' on all of them in a bulk; this involved complex timestamping and file-locking logic. It was also brittle in any slightly-unusual setup, because 'elisp-comp' operated by copying all of the elisp files to be compiled into a temporary sub-directory and compiling them in there, the copying the resulting byte-compile files back in the build directory. This patch removes all of that juggling and chicanery in favour of defining a much simpler '.el.elc' suffix rule. Not only this is simpler, but it also interacts better with "make -jN" calls, which are becoming more and more common and useful on today's increasingly multicore systems. * Makefile.am (dist_script_DATA): Remove 'elisp-comp'. * automake.in (@common_files): Likewise. (handle_emacs_lisp): Do not require 'elisp-comp'. * doc/automake.texi: Remove references to 'elisp-comp'. * lib/am/lisp.am: Define elisp compilation via a suffix rule; this basically amounts to a complete re-write of the lisp byte-compilation rules. * lib/elisp-comp: Remove. * t/add-missing.tap: Remove elisp-comp test. * t/dist-auxdir-many-subdirs.sh: Remove reference to elisp-comp. * t/primary-prefix-invalid-couples.tap: Likewise. * t/primary-prefix-valid-couples.sh: Likewise. * t/lisp4.sh: Remove reference to elc-stamp. * t/lisp5.sh: Likewise. * t/lisp6.sh: Likewise. * t/lisp3.sh: Likewise. Also remove the recompilation check that involves a (message) call. * t/lisp7.sh: Remove check for "Warnings can be ignored".

Stefano Lattarini c2a52bf0 2012-06-24T10:36:15 tests: simpler workaround for shells losing the exit status in exit trap Now that we can assume our tests are run by a decent POSIX shell, we can simplify our workaround aimed at having the exit status propagated correctly to the code in the exit trap. Unfortunately, we cannot dispense with such a workaround altogether, because it's still required by some shells we need to support (at least Solaris 10 /bin/ksh and /usr/xpg4/bin/sh). For more information about the need of that workaround, see the entry about 'trap' in the section "Limitations of Shell Builtins" in the Autoconf manual: <http://www.gnu.org/software/autoconf/manual/autoconf.html#trap> The new workaround has been tested successfully with the following shells: - Bash 4.1 - Bash 3.2 - Bash 3.0 - Bash 2.05b - dash 0.5.5.1 - dash 0.5.2 - AT&T Ksh 93u (from official Debian package) - MirBSD Korn Shell 40.2 (from official Debian package) - Solaris 9, 10 and 11 /bin/ksh - Solaris 9, 10 and 11 /usr/xpg4/bin/sh - NetBSD 5.1 /bin/sh - NetBSD 5.1 /bin/ksh * t/ax/test-init.sh (Exit): Rename ... (_am_exit): ... like this. (exit): New alias for '_am_exit'. We cannot simply redefine 'exit' as a shell function, because some shells (dash 0.5.5.1, Solaris 10 /bin/ksh and /usr/xpg4/bin/sh) do not allow it. (_am_exit, trap): Add extra escaping for 'exit' calls, to ensure we really invoke the 'exit' builtin and not our alias with the same name. * configure.ac: Check that the shell selected to run our testsuite supports aliases named like shell builtins. * t/REAMDE: Adjust. * All tests: Adjust, by simply using 'exit' instead of 'Exit'. * t/self-check-explicit-skips.sh: Adjust: the first usage of 'exit' after it has been redefined as an alias must be on a new line w.r.t. that where the alias is defined, in order for the redefinition to be honored. * syntax-checks.mk (sc_tests_Exit_not_exit): Delete. (sc_tests_exit_not_Exit): New. (syntax_check_rules): Adjust. (sc_tests_automake_fails): Simplify the recipe a little. * Several tests: Remove now useless spurious quoting once required to placate the 'sc_tests_Exit_not_exit' maintainer check. * gen-testsuite-part: Likewise. Also, avoid uses of 'Exit' in the generated scripts. Signed-off-by: Stefano Lattarini <stefano.lattarini@gmail.com>

Stefano Lattarini 6e713425 2012-06-14T13:13:58 tests: use more POSIX shell features our test scripts Since commit 'v1.12-36-g2d68fd9' of 2012-05-07, "configure: search a sturdy POSIX shell to be used in the testsuite", the shell running our test script is assured to be a POSIX-conforming shell, so we can use the more modern and flexible idioms and features that we couldn't use when we also aimed at compatibility with non-POSIX Bourne shells, like Solaris /bin/sh. * t/README: Suggest to use POSIX shell features liberally in test cases, with possible exception of Makefile recipes and configure shell code. * Several tests: Adjust to use more POSIX shell features; e.g., $(...) rather than `...`, $((...)) rather than `expr ...`, "if ! CMD; then ..." instead of "if CMD; then :; else ...", and so on. In several places, when using the 'test' built-in, prefer '-eq' over '=' for numeric comparisons, and prefer "grep -c PATTERN FILE" over "grep PATTERN FILE | wc -l". Throw in other low-hanging easy improvements and fixlets while we are at it. * t/ax/depcomp.sh, t/ax/tap-summary-aux.sh, t/ax/tap-functions.sh, defs, defs-static.in: Likewise.

Stefano Lattarini 8a5096d1 2012-04-06T13:12:25 tests: rename 'tests/' => 't/', '*.test' => '*.sh' When we (soon) convert the Automake testsuite to a non-recursive make setup, we'll have to fix the entries of $(TESTS) to be prepended with the subdirectory they are in; this will increase the length of $(TESTS), and thus increase the possibility of exceeding the command-line length limits on some systems (most notably, MinGW/MSYS). See automake bug#7868 for more information. Thus we rename the 'tests/' subdirectory to 't/', and each 'x.test' script in there to 'x.sh'; this way, the $(TESTS) entry 'foo.test' will become 't/foo.sh', which have the same number of characters. * tests/: Rename ... * t/: ... to this. * t/*.test: Rename ... * t/*.sh: ... to this. * t/.gitignore: Removed as obsolete. * t/defs: Adjust. * t/gen-testsuite-part: Likewise. * t/list-of-tests.mk: Likewise. * t/ccnoco.sh: Likewise. * t/ccnoco3.sh: Likewise. * t/self-check-cleanup.tap: Likewise. * t/self-check-dir.tap: Likewise. * t/self-check-me.tap: Likewise. * t/self-check-reexec.tap: Likewise. * README: Likewise. * bootstrap: Likewise * configure.ac: Likewise. * Makefile.am: Likewise. * .gitignore: Likewise. * syntax-check.mk: Likewise.
