missing: --run is supported again (as a no-op) for use by older automake

Commit v1.12.1-87-ga22717d of 2012-06-21 ("missing: do not touch
timestamps; only warn for out-of-date files") has removed the '--run'

<http://lists.gnu.org/archive/html/bug-m4/2012-06/msg00001.html>), then
the 'Makefile' in that project will fail due to passing the '--run'

12 years agomissing: do not touch timestamps; only warn for out-of-date files
Stefano Lattarini [Fri, 15 Jun 2012 09:13:00 +0000 (11:13 +0200)]
missing: do not touch timestamps; only warn for out-of-date files

Before this change, the missing script had a twofold role:

  - it warned the user if some required maintainer tools was missing,
    or too old;

  - in such a case, it tried to "fix" the timestamp of the files that
    should have been rebuilt by that tool (without actually updating
    the file contents, of course), to allow the build to continue.

The second capability used to be quite useful in the days when most
projects committed files generated by maintainer-only tools in their
VCS repository (today the trend is not to keep such generated files
VCS-committed anymore).  In such a setup, the "timestamp-fixing"
capability of 'missing' was quite useful, in that it allowed users
lacking some required maintainer tool to build from a VCS checkout
in the face of skewed timestamps (as could have been caused by
"cvs update" or "git checkout").

But then, when the automatic remake rules kicked in due to the
generated files being *actually out-of-date* (e.g., because the user
had modified 'configure.ac' but lacked a modern-enough autoconf to
rebuild it), that behaviour of 'missing' caused the same problem that
plagued AM_MAINTAINER_MODE; i.e., the user would get non-dependable
builds and inconsistent statuses of the build tree -- changes to
source files don't reflect on generated files, and this can be very
confusing and cause hard-to-spot errors).

So we now believe that the best approach to deal with timestamp-related
issues is not to have 'missing' to "automagically" try to resolve
them (with all the risk and brittleness entailed), but rather to
suggest those projects still keeping generated files committed in their
VCS to provide a proper (say) 'fix-timestamp.sh' script that touches
the timestamp of the checked-out files, to ensure no spurious rebuild
will be triggered.  As a bonus, such a script can be more aware of the
particularities, nooks and corner cases of a project, and thus more
reliable than the old 'missing' script.

An example of this approach is offered by GNU awk (release 4.0.1, Git
tag 'gawk-4.0.1', commit b85b04e8).  The GNU awk maintainers commit
the Autotools-generated files (configure, Makefile.in, etc.) and other
generated in the project's Git repository, but offer a useful script
'bootstrap.sh' that fixes the timestamps of those files, to ensure no
useless remake is triggered in a freshly cloned repository:

    #! /bin/sh
    # bootstrap.sh --- touch relevant files to avoid out-of-date issues
    #                  in Git sandboxes
    touch aclocal.m4
    find awklib -type f -print | xargs touch
    sleep 1
    touch configure
    sleep 2
    touch configh.in
    sleep 1
    touch test/Maketests
    find . -name Makefile.in -print | xargs touch
    touch doc/*.info
    touch po/*.gmo
    touch po/stamp-po
    touch awkgram.c
    touch command.c
    touch version.c

A similar, simplified script is also reported as an example in the
manual.

* NEWS: Update.
* doc/automake.texi (Auxiliary Programs, maintainer-mod): Update.
(CVS): Do not suggest that 'missing' can "automagically" fix botched

example of a custom 'fix-timestamp.sh' script that can be used to

In the documentation, we shouldn't confuse "packages using subdirectories"

itself).

In fact, make recursion should be used as seldom as possible, because it
makes the build system more brittle and dependency declarations less
faithful.  See Peter Miller's article "Recursive Make Considered Harmful"

make recursion does.  Observe that such a system, albeit being very
widespread, has its own issues and drawbacks, and that one can have a
non-recursive setup also for projects using complex directory layout.

of automatic dependency tracking: the '.Po' and '.Plo' files does not
depend on any C header or source file, ever!

So it seems that the distinction between "normal" and "cleaning"
recursive targets is a stale leftover of an older implementation of
the automatic dependency tracking.  In fact, the Automake History
manual seems to confirm this suspect; the section "First Take on
Dependency Tracking" reads:

    Because each .P file was a dependency of Makefile, this meant
    that dependency tracking was done eagerly by make.  For instance,
    "make clean" would cause all the dependency files to be updated,
    and then immediately removed.  This eagerness also caused problems
    with some configurations; if a certain source file could not be
    compiled on a given architecture for some reason, dependency
    tracking would fail, aborting the entire build.

and the following section "Dependencies As Side Effects" reads:

    In this approach, the .P files were included using the -include
    command, which let us create these files lazily.  This avoided
    the "make clean" problem.

So the distinction between "normal" and "cleaning" recursive targets
has likely been obsolete since by then already.  We can thus remove
such distinction, thus reducing some complications and duplication in
our rules.  Doing so, the whole testsuite still passes (both with GCC
and Sun C 5.9), even the test 'c-demo.sh', which, among the other
things, exercise the setup described in the obsolete code comment
referenced above.

Finally, note that we still keep '$(RECURSIVE_CLEAN_TARGETS)' and
'$(RECURSIVE_TARGETS)' as two distinct variables, to ensure a better
backward-compatibility for any user-defined rules that happen to use
those variables.

perf: beginning of a performance testsuite

Some tests in the Automake testsuite already aims only at verifying
the performance, rather than the correctness, of some operations.
Still, they are somewhat shoehorned and forced into the PASS/FAIL
framework (say, with the 'ulimit' shell builtin used to verify some
operation doesn't take up too much time or memory), but that is
conceptually a stretch, and has already caused problems in practice
(see automake bug#11512 for an example).

So we start moving the "performance tests" out of the testsuite proper,
and make them run only "on demand" (when the user exports the variable
'AM_TESTSUITE_PERF' to "yes").  Ideally, we should provide those tests
with a custom runner/driver that measures and displays the relevant
performance information, but doing that correctly and with the right

ylwrap: preserve subdirectories in "#line" munging

If Automake is used in non-recursive mode and one of the inputs is a
yacc file, for example, "src/grammar.y", ylwrap will remove too many
directories from the output file when it adjusts the paths in it.
This results in #line directives referring to "grammar.y" instead of
"src/grammar.y".

This is a result of $input_rx simply taking all the directory
components of the absolute input path and removing them.

One solution is to store the path passed to ylwrap and replace
$input_rx with it.  This is what we do.

Suggestion and initial patch (without tests) by Nikolai Weibull:
