* tests: simplify checks for some expected variables values in MakefilesStefano Lattarini2013-06-195-48/+37
| | | | | | | | | | | | | | | | | | | | | Do so by using our custom 'is' auxiliary script rather than grepping the output from make. This is more natural, more robust, and often shorter to write. Unfortunately, we can't do that in all cases: sometimes we really need to match the content of a variable against a regular expressions, and we can't know nor are interested in its exact value. This is basically a follow-up on commit v1.11-1830-g96401cb of 2012-02-08 (tests: better way to compare lists in Makefile rules). * t/subst-no-trailing-empty-line.sh: Adjust. * t/pluseq10.sh: Likewise. * t/check5.sh: Likewise, and enhance a little while at it. * t/check7.sh: Likewise. * t/exeext.sh: Likewise.

I thought that the sleeps implicit in the configure invocation were enough, but they were not, actually. Here is what can happen: 1. The config.status script is generated by a configure run. 2. ./config.status and make are run. 3. The 'print-version' script is modified. 4. Since that script is listed in $(CONFIGURE_DEPENDENCIES), autoconf is re-run. 5. On a fast-enough machine, the three steps 2-4 above, even combined, might have taken less than a second to run; 6. If the filesystem doesn't have a sub-second timestamp resolution, that means the newly-generated configure has the same timestamp of the old config.status; 7. So, config.status is not re-run, and the Makefiles are not updated. 8. Spurious failure! So we really need more explicit sleeps. Signed-off-by: Stefano Lattarini <stefano.lattarini@gmail.com>

This behaviour is highly inconsistent with that of the other macros related to C compiler checks -- which test only $CC. It can also cause unwarranted uses of the 'compile' script on systems where the default 'cc' is inferior, but the user is compiling with a proper, different compiler (e.g., gcc). ** Practical problems with our previous implementation of C support m4 macros in Automake: - AM_PROG_AR must now be called *before* AC_PROG_CC; this wasn't the case before, and it turns out there are packages in the wild that relied on the old behaviour. - The cross-referenced requirements and macro rewrites juggled among AC_PROG_CC, AC_PROG_CC_C_O and AM_PROG_CC_C_O caused warnings in autoconf; for example, in our test 't/libobj3.sh', we could see warnings like these (here slightly tweaked for legibility): configure.ac:5: AC_REQUIRE: `AC_PROG_CC' expanded before required autoconf/c.m4:567: AC_PROG_CC_C_O is expanded from... autoconf/c.m4:429: AC_LANG_COMPILER(C) is expanded from... autoconf/lang.m4:329: AC_LANG_COMPILER_REQUIRE is expanded from... autoconf/general.m4:2606: AC_COMPILE_IFELSE is expanded from... m4sugar/m4sh.m4:639: AS_IF is expanded from... autoconf/general.m4:2031: AC_CACHE_VAL is expanded from... autoconf/general.m4:2052: AC_CACHE_CHECK is expanded from... aclocal.m4:70: AM_PROG_AR is expanded from... configure.ac:5: the top level ** Fix all of that: We fix all of the described issues with a new internal m4 macro _AM_PROG_CC_C_O (inspired to, but not based on, AC_PROG_CC_C_O) that gets tacked on to AC_PROG_CC automatically (this is done in the Automake-generated aclocal.m4) and that takes care of checking and adjusting '$CC' for "-c -o" support. The macro AM_PROG_CC_C_O is still present, but is now just a thin wrapper around such Automake-enhanced AC_PROG_CC. It is worth noting that the present patch causes three slight *backward-incompatibilities*: 1. The name cache variable used by AM_PROG_CC_C_O is no longer computed (at configure runtime!) from the content of '$CC', but is statically defined as 'am_cv_prog_cc_c_o'. 2. 'cc' is no longer checked by AM_PROG_CC_C_O, only '$CC' is. 3. AM_PROG_CC_C_O no longer AC_DEFINE the C preprocessor symbol 'NO_MINUS_C_MINUS_O'. Given however that the third change can easily be worked around, that the first two changes can be legitimately seen as bug fixes, and that the new semantics introduced by such changes will simplify the transition to Automake 2.0 (when the 'subdir-objects' will always be enabled unconditionally), we believe they are acceptable to be shipped with Automake 1.14. With this patch, we also revert some of the testsuite adjustments done in previous commit v1.13.2-178-g9877109 of 2013-05-24 (compile: rewrite AC_PROG_CC with AM_PROG_CC_C_O contents). Such adjustments are no longer needed. * m4/minuso.m4 (_AM_PROG_CC_C_O): New internal macro, basically and adjusted version of a merge between Autoconf-provided AC_PROG_CC_C_O and our old implementation of AM_PROG_CC_C_O. (AM_PROG_CC_C_O): Redefine as a simple wrapper around AC_PROG_CC. * m4/init.m4 (AC_PROG_CC): Append _AM_PROG_CC_C_O, not AM_PROG_CC_C_O, to the pre-existing expansion of this macro. * m4/ar-lib.m4 (AM_PROG_AR): No longer require it to be expanded after AC_PROG_CC. * t/aclocal-deps.sh: Move AC_PROG_CC invocation after AC_PROG_RANLIB and AM_PROG_AR invocations.

Not only this change simplifies the code a little, but has the welcome collateral effect of making automatic dependency tracking work better with compilers that doesn't grasp the '-c' and '-o' options together. Issues in that setup have been caught by several failures in the target 'check-no-cc-c-o'. Unfortunately, this change has less welcome collateral effects: 1. AM_PROG_AR must now be called *after* AC_PROG_CC; 2. Autoconf emits extra warnings when used with Automake-generated aclocal.m4. These are unacceptable regressions for a release, but since we are going to fix them soon enough in a follow-up patch (surely to be applied before Automake 1.14 is released) we don't worry too much. * m4/init.m4: Redefine AC_PROG_CC early, to automatically invoke AM_PROG_CC_C_O as well. Accordingly, drop now-unneeded "automagical" AM_PROG_CC_C_O expansion at later time (which took place thanks to a AC_CONFIG_COMMANDS_PRE call). * m4/minuso.m4 (AM_PROG_CC_C_O): Ensure the expansion of the body of this macro takes place with C as "current Autoconf language" (use AC_LANG_PUSH/AC_LANG_POP). * m4/ar-lib.m4 (AM_PROG_AR): Likewise. Also, require this macro to be expanded *after* AC_PROG_CC (so that any rewrite of $CC, if required, has already taken place). * t/add-missing.tap: Adjust to avoid spurious failures. * t/aclocal-deps.sh: Likewise, by having AM_PROG_AR called *after* AC_PROG_CC. * t/subobj-clean-lt-pr10697.sh: Likewise. * t/alloca.sh: Likewise. * t/condlib.sh: Likewise. * t/discover.sh: Likewise. * t/objc-megademo.sh: Likewise. * t/ccnoco.sh: Extend a little. * t/ccnoco-deps.sh: New test. * t/ccnoco-lib.sh: Likewise. * t/ccnoco-lt.sh: Likewise. * t/list-of-tests.mk: Add them.
