11 years agotests: use append mode to capture parallel make output
Stefano Lattarini [Thu, 23 May 2013 23:13:40 +0000 (01:13 +0200)]
tests: use append mode to capture parallel make output

This will allow us to run the Automake testsuite forcing all the make
invocations in the test cases to run in parallel mode [1], but without
hitting the spurious failure reported in automake bug#11413.

See also:
<http://lists.gnu.org/archive/html/bug-make/2013-05/msg00135.html>

The make invocations in the test cases can be forced to run in parallel
mode by, e.g., invoking "make check" like this:

      make check AM_TESTSUITE_MAKE="make -j16"

The possible spurious failures hinted above are due to the fact that
the redirected output of parallel make can racily lose lines.  For
example, if GNU make (3.82) is run with -j10 on a Makefile like this:

    all = 0 1 2 3 4 5 6 7 8 9
    default: $(all)
    $(all):
            @sleep 0.$$(($RANDOM % 10)); echo $@

and has its standard output redirected in overwrite-mode to a regular
file, it looses a line of that output every 15 runs or so on a Fedora
17 system with 64 ppc64 cores.  Redirection in append mode does not
suffer of this problem, as explained here:
<http://lists.gnu.org/archive/html/automake-patches/2009-03/msg00073.html>

Stefano Lattarini [Tue, 21 May 2013 18:22:17 +0000 (20:22 +0200)]
tests: run_make: options to do command redirection

Let's improve the API of the 'run_make()' helper shell function by
adding three new options:

  -O   Save the standard output from make on disk, in a regular file
       named 'stdout'.

  -E   Save the standard error from make on disk, in a regular file
       named 'stderr'.

  -M   Save both the standard output and standard error from make on
       disk, in a regular file named 'output'. This option supersedes
       both the '-O' and '-E' options.

This new API has two main advantages.

  1. Its use will allow us to get rid of more cumbersome idioms
     like, e.g.,

       $MAKE check >stdout && { cat stdout; exit 1; }
       cat stdout

     That can now be substituted with a simpler one:

       run_make -e FAIL -O check

  2. More importantly, using the new API we will prevent any extra output
     from the shell traces of the code in run_make to be redirected along
     with the make stderr (where that was redirected).  This problem was
     present in usages like, e.g.,

       run_make TESTS=foo.test check 2>stderr && exit 1
       grep 'expected error message' stderr

     Such usages are now to be rewritten as follows:

       run_make -e FAIL -E TESTS=foo.test check
       grep 'expected error message' stderr

     ensuring that 'stderr' won't end up containing unrelated stuff.

Note that we do not convert in bulk the old idioms and the use of
redirected 'run_make' invocations with this patch.  We only convert
some occurrences, to ensure that the new implementation of 'run_make'
is sound enough.  More sweeping conversions will likely be done in
follow-up patches.

"patch bomb" effect (this commit is already too much of a bomb itself).
What we do in this commit is to get rid of all "$MAKE -e" invocations.

We admit that the implementation and feature-set of 'run_make()' are
far from perfect, but good enough for our current purposes.  We'll
improve 'run_make()' if and when the need arises.

* syntax-checks.mk (sc_tests_no_make_e): New syntax check, guard against
the use of "$MAKE -e".
(syntax_check_rules): Add it.
(sc_tests_overriding_macros_on_cmdline): Adjust.
(lint): New, alias for 'maintainer-check', for lazy typists.  Idea
backported from the 'maint' branch (Automake 1.13a).
* t/ax/am-test-lib.sh (run_make): New function.  Run $MAKE with the
given command-line arguments, handling command-line override of variable
definitions in a smart way (using AM_MAKEFLAGS if a non-GNU make
implementation is detected to be in use).
(useless_vpath_rebuild): Adjust to use 'run_make', to avoid a spurious
maintainer check failure.
(yl_distcheck): Use 'run_make' rather than bare '$MAKE'.
(single_quote, append_single_quoted, is_valid_varname): New auxiliary
function, used, directly or indirectly, by it.
* Many tests: Adjust to avoid the use of "$MAKE -e", and prefer the
use of 'run_make' in few other contexts as well, where it makes sense.
Other minor fixlets while at it.

11 years agotests: sanitize 'unset' usages
Stefano Lattarini [Fri, 17 May 2013 11:45:44 +0000 (13:45 +0200)]
tests: sanitize 'unset' usages

In some shells (e.g., Solaris 10 /bin/ksh, or NetBSD 5.1 /bin/sh),
"unset VAR" returns a non-zero exit status in case the VAR variable
is already unset.  This doesn't interact well with our usage of
"set -e" in the testsuite.  So far, we've avoided spurious failures
by either explicitly ignoring the exit status from unset:

    unset VAR || :

or explicitly ensuring that a variable is set, before trying to
unset it:

    VAR=; unset VAR

But we can do better, by aliasing the 'unset' command to a custom
function that will take care of these details for us.  This will
avoid us annoying spurious failures in the future, failures that
have already bitten us too much times.  For an example, refer to

make flags analysis: cater to GNU make 3.83 (still unreleased as of now)

The current development version of GNU make (that is planned to become
GNU make 3.83, sooner or later) has changed the format its $(MFLAGS)
variable slightly, removing the space between an option and its argument:

   # With GNU make 3.82, compiled from official tarball:
   $ make -f- <<<'all:; @echo "$$MFLAGS"' -I none
   -I none

   -Inone

This was done on purpose, in order to support more easily the new
option '-O', which takes an optional argument; see:

  <http://lists.gnu.org/archive/html/bug-make/2013-05/msg00001.html>

11 years agotar: format 'ustar' cannot support UID/GID longer than 21 bits
Stefano Lattarini [Sun, 17 Feb 2013 15:42:46 +0000 (16:42 +0100)]
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.
