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).

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.

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.

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.

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.
