Assume we have package satisfying the following conditions:
(1) automatic dependency tracking is enabled;
(2) the 'subdir-objects' Automake option is enabled;
(3) the package uses a recursive make setup.
Also assume that:
(a) a subdir Makefile declares a foo_SOURCES variable containing
a source file in the parent directory;
(b) that parent Makefile declare a compiled program itself.
Then BSD and Solaris make used to fail when running "make distclean",
because the 'distclean' target of the subdir Makefile removed the
whole '.deps' directory before the parent Makefile was done with the
included '.Po' makefile fragments in that directory. This issue was
revealed by failures in the 'subobj-vpath-pr13928.sh' test when those
make implementations were used.
We fix the issue by ensuring the 'distclean' target of any Makefile
only removed the '.Po' makefile fragments included by it, rather than
the whole '.deps' directory where such files resides.
This change should be the last step in fixing automake bug#13928
for good.
* bin/automake.in (handle_languages), lib/am/depend.am: Adjust
to implement the new 'distclean' logic.
* t/pr224.sh: Adjust to avoid a spurious failure.
* PLANS/subdir-objects.txt: Update.

See automake bug#10828.
POSIX will say in a future version that running "rm -f" with no argument
is OK: <http://austingroupbugs.net/view.php?id=542>).
We want to be able to make that assumption in our Makefile recipes.
So we introduce an aggressive probe to check that the usage we want is
actually supported "in the wild" to an acceptable degree.
* m4/init.m4 (AM_INIT_AUTOMAKE): Implement the probe. To make any issue
more visible, cause the running configure to be aborted by default if
the 'rm' program in use doesn't match our expectations; the user can
still override this though, by setting the ACCEPT_INFERIOR_RM_PROGRAM
environment variable to "yes".
* t/spy-rm.tap: Update heading comments.
* t/rm-f-probe.sh: New test.
* t/list-of-tests.mk: Add it.

OK, this is getting ridiculous, but we cannot remove this macro yet
(and, yes, the fault for this mess lies entirely on me; let's not
dwell on that, thank you very much).
Gettext (so far the greatest "offender" in the use of AM_PROG_MKDIR), in
its latest release 0.18.2, has removed all the uses of that macro still
present in its code base. So I thought we could finally and safely
remove it. Wrong. If a package's 'configure.ac' contains a call like:
AM_GNU_GETTEXT_VERSION([0.18])
then the 'autopoint' script will bring the data files from the Gettext
release *1.18* into the package's tree -- yes, even even if the developer
has installed *and is using* Gettext 1.18.2! Now, these data files
comprise m4 files (that will be seen by subsequent aclocal and autoconf
calls), and of course, the pre-0.18.2 version of some of these files
still contains occurrences of AM_PROG_MKDIR_P -- so Automake 1.13 errors
out, and we lose. This has already happened in practice:
<http://lists.gnu.org/archive/html/bug-grep/2013-01/msg00003.html>
Moreover, while we might see it as not unreasonable to ask a developer
using Automake 1.14 to also update Gettext to 1.18.2, that would not
be enough; in order for gettext to use the correct data files, our
developer would have to update his configure.ac to read:
AM_GNU_GETTEXT_VERSION([0.18.2])
thus requiring *all* of his co-developers to install Gettext 1.18.2,
even if they are still using, say, Automake 1.13. Bad.
So we re-instate this macro as a simple alias for AC_PROG_MKDIR (plus
a non-fatal runtime warning in the 'obsolete' category), and drop any
plan to remove it (see how much good those plans have done us so far).
Note that NEWS is not yet adjusted, since we'll have to adjust it in
maint before (to minimize spurious merge conflicts).
* doc/automake.texi: Update.
* PLANS/obsolete-removed/am-prog-mkdir-p.txt: Likewise.
* t/gettext-macros.sh: Adjust.
* t/am-prog-mkdir-p.sh: New test.
* t/mkdir_p.sh: Remove, folded into the new one.
* t/am-prog-mkdir-p-no-more: Remove as superseded.
* t/list-of-tests.mk: Adjust.
* t/obsolete-err.m4: Re-instate AM_PROG_MKDIR_P as a working
alias for AC_PROG_MKDIR_P (albeit giving runtime warnings, and
calling AC_SUBST on 'mkdir_p' too).
* m4/init.m4 (AM_INIT_AUTOMAKE): No longer call AC_SUBST for
'mkdir_p', as that is once again AM_PROG_MKDIR_P's business.

Individual files or sub-directories about future and on-going
development plans in Automake will be added in follow-up commits.
This new set of documents is meant to help ensure a more controlled
and smooth development and evolution for Automake, in several ways.
- Having the plans clearly spelled out should will avoid messy
roadmaps with no clear way forward or with muddy or ill-defined
aims or purposes; a trap this is too easy to fall into.
- Keeping planned changes cooking and re-hashed for a while should
ensure rough edges are smoothed up, transitions are planned in a
proper way (hopefully avoiding debacles like the AM_MKDIR_PROG_P
deprecation and the AM_CONFIG_HEADER too-abrupt removal), and
"power users" have more chances of getting informed in due time,
thus having all the time to prepare for the changes or raise
objections against them.
- Having the plans clearly stated and registered in a "centralized"
location should make it more difficult to them to slip through
the cracks, getting forgotten or (worse) only half-implemented.
- Even for discussions and plans registered on the Bug Tracker
as well, a corresponding entry in the PLANS directory can help
in keeping main ideas summarized, and consensus and/or objections
registered and easily compared.
Motivation:
<http://blog.flameeyes.eu/2013/01/autotools-mythbuster-automake-pains>
Not a flatting picture for us (and maybe a little too harsh), but
basically true and even spot-on in some regards.
* PLANS/README: New.
* Makefile.am (EXTRA_DIST): Distribute the whole PLANS directory.
