Stefano Lattarini 74017b56 2013-05-16T12:18:43 tests: remove exec bit from all of them ('micro' branch) It gives the impression that they are directly runnable, as with "./t/foo.sh", but it has been a while since that was the case. Today, tests are runnable only through "make check" or "./runtest". This change is for the 'micro' branch (automake 1.13.2a). It will soon be followed by similar patches for the 'maint' branch (automake 1.13a) and the 'master' branch (automake 1.99a). * t/*.sh, t/*.tap: Remove executable bit. * maint.mk (sc_tests_executable): Remove. (syntax_check_rules): Adjust. * gen-testsuite-part: Set permissions of generated tests to '444' (-r--r--r--), rather than 555 (-r-xr-xr-x).

Stefano Lattarini edfd3bc4 2013-02-17T16:42:46 tar: format 'ustar' cannot support UID/GID longer than 21 bits See automake bug#8343 and bug#13588. POSIX 1988 'ustar' format is defined with *fixed-size* fields. There is notably a 21 bits limit (2097151) for the UID and the GID. Tom Rini tom_rini@mentor.com says (in bug#8343): When the user has a UID or GID that is larger than the ustar format supports, pax does not error out gracefully in some cases (FC13). Marc Herbert <marc.herbert@intel.com> adds (in bug#8343): When "configure" is run by a user with an UID bigger than 21 bits, BSD pax 3.4 aborts when trying to create the 'conftest.tar' test archive and leaves an empty or corrupted conftest.tar file behind. In the next step, pax tries to extract this incomplete or corrupted archive and this *** hangs the whole ./configure script ***. Note: GNU cpio 2.9 pretends to pass the test but it is a LIE: it silently truncates any big UID to its lower 21 bits. I don't know what can be the consequences of this lie. I think there is currently a design issue in automake/m4/tar.m4 considering that a ustar archive should should *never* succeed when ./configure is run from a big user ID. Months later, Petr Hracek <phracek@redhat.com> reports a similar issue (in bug#13588) for Fedora 17: I am trying to solve problem in case a user is created with big UID and during configuration pax hangs with message ATTENTION! pax archive volume change required. Ready for archive volume: 1 Input archive name or "." to quit pax. Archive name > and needs user interaction. Reference: <https://bugzilla.redhat.com/show_bug.cgi?id=843376> Time to fix this issue, on the line of a preliminary patch provided by Petr Hracek in bug#13588. The final patch ended up being remarkably different from that original proposition, though. * m4/tar.m4 (_AM_PROG_TAR): If the UID or GID of the current user is too high (> 2097151), the 'ustar' format cannot work. Adjust checks accordingly. Some related code reordering and clean-up. * t/tar-ustar-id-too-high.sh: New test. * t/list-of-tests.mk: Add it. * t/tar.sh: While at it, tweak and enhance a little. * t/tar2.sh: Likewise. * t/tar3.sh: Likewise. * t/tar-override.sh: Likewise. * NEWS: Update. * THANKS: Likewise.

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.

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.
