    make check TESTS="x.test k.test"

which are somewhat unusual, but not invalid.  So we need a more resilient
implementation, as we did for the detection of the '-n' flag.

This implementation is now provided by the new private macro
'$(am__make_keepgoing)' (introduced in recent commits); so we can

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.

  perl: perl subroutine prototypes are problematic, don't use them

11 years agoperl: perl subroutine prototypes are problematic, don't use them
Stefano Lattarini [Tue, 5 Mar 2013 17:30:03 +0000 (18:30 +0100)]
perl: perl subroutine prototypes are problematic, don't use them

Basically, in perl, "subroutine prototypes" are not prototypes at all;
rather, they are a trick to allow user-defined subroutines that behave
like perl built-in functions.  For example, prototyped subroutines can
be called without parentheses, and can impose context on their arguments.

Such semantics can be useful in some selected situations, but might also
easily cause unexpected and harmful behaviours and side effects if we
try to use perl prototypes as we would use C prototypes.

See the excellent article "Far More than Everything You've Ever Wanted
to Know about Prototypes in Perl" by Tom Christiansen for more detailed
information:

    <http://www.perlmonks.org/?node_id=861966>
    <http://web.archive.org/web/20080421062920/\
     library.n0i.net/programming/perl/articles/fm_prototypes>

It is important to note that modern perl allows a non-predeclared
subroutine to be called without the '&' character, as long as its
call uses proper parentheses:

    foo 'str', 2;   # will trigger errors if foo is not predeclared
    foo('str', 2);  # ok even if foo is not predeclared
    &foo('str', 2); # ditto; but the '&' is old-style and redundant

Note also that the prototype indicating "no argument":

    sub func() { ... }

can actually be useful, and has no discernible downsides, so we'll
keep using it where it makes sense.

Also, in few, selected cases, we *want* to have subroutines behave like
perl builtins (e.g., we want the 'append_exeext' function to be able
to take a code block as first argument).  In such cases, we will of
course continue to make use of perl subroutine prototypes.

Let's finally see an example that might clarify the kind of problems the
use of subroutine prototypes in perl can cause.  This is just scratching
the surface; there are several other aspects, typically subtler and more
dangerous, that are not touched here.

If you have the prototyped subroutine definition:

    sub foo ($@)
    {
        my $s = shift;
        print "SCALAR: $s\n";
        print "ARRAY: @_\n";
    }

and call 'foo' in code like:

    @list = (-1, 0, 1);
    foo(@list);

you won't get a compile-time nor a runtime error (as a naive interpretation
of the "prototype" characterization would let you think).  Rather, the
prototype will cause the array '@list' will be coerced into scalar context
before being passed too 'foo', which means that its *length* (3) will be
passed to 'foo' as first argument; and since no further arguments are
present after '@list', that *void* will be coerced to an empty list before
being passed to 'foo'.

So code above will have the result of printing:

  SCALAR: 3
  ARRAY:

Quite tricky, and definitely a behaviour we don't want to rely on.

* automake.in: Delete most subroutine prototypes.  Fix few of the
remaining ones.  Related minor simplifications and adjustments.
* lib/gen-perl-protos: Adjust.

aclocal: just warn if the primary local m4 dir doesn't exist (don't error)

Related to automake bug#13514.

Every package which does not need to have the local m4 macro
directory pre-existing in the version control system (because
e.g., it does not have nor need any private m4 macros) would
fail during the "autoreconf -vfi" phase if AC_CONFIG_MACRO_DIRS([m4])
is specified in configure.ac (it could be to instruct tools like
'autopoint' and 'libtoolize' to use 'm4' as the local directory
where to install definitions of their m4 macros, and to instruct
aclocal to look into it).  The failure would go like this:

  autoreconf: Entering directory `.'
  autoreconf: running: aclocal --force
  aclocal: error: couldn't open directory 'm4': No such file or directory
  autoreconf: aclocal failed with exit status: 1

The problem is that when 'aclocal' is run for the first time during
'autoreconf', the directory 'm4' does not exist yet.  It will be
created by e.g., 'libtoolize' or 'autopoint' later on.  During the
second 'aclocal' run, the 'm4' directory exists and aclocal does not
complain.

To work around this issue, we degrade the error to a simple warning.
The warning is still quite useful when aclocal is run by hand - so
we are not removing completely.
