12 years agotexi: require Texinfo >= 4.9, related enhancements
Stefano Lattarini [Sun, 17 Jun 2012 10:23:18 +0000 (12:23 +0200)]
texi: require Texinfo >= 4.9, related enhancements

We start passing the '--build-dir' option to the texi2dvi and texi2pdf
invocations done in our Texinfo-related rules.  The argument for this
option will be specific for each info_TEXINFOS entry, to work around a
texi2dvi bug that could otherwise cause racy failures in parallel make
builds:
<http://lists.gnu.org/archive/html/automake-patches/2012-06/msg00073.html>
That bug seems already fixed in the development version of texi2dvi,
though:
<http://lists.gnu.org/archive/html/automake-patches/2012-06/msg00074.html>
so the details of our '--build-dir' usage can be revisited once we can
assume Texinfo 5.0 or later.

Since the '--build-dir' options has been only supported since Texinfo
4.9, we lose compatibility with all older Texinfo versions.

But we also get some real improvements.

First, the '--build-dir' option implies the '--tidy' option; this, like
the '--clean' option that we were formerly using, prevents cluttering of
the build directory with all the TeX and Texinfo auxiliary files and
build by-products, but, differently from '--clean', keeps them around
for later re-runs to use; this shortens the rebuild times considerably.

Second, the use of '--build-dir' also allows us to specify different
build directories for the PDF and DVI output, preventing the rules
building them from stomping on each other's feet when run in parallel.
This is demonstrated by the test cases 'txinfo-no-clutter.sh' and
'txinfo33.sh', which before this change used to fail when run with
MAKE="make -j4", but now succeed even in that case.

* NEWS: Update.
* lib/am/texibuilds.am: Do not try to avoid texi2dvi/texi2pdf option
'-o'; it has been supported since Texinfo 4.1, and we now require
Texinfo >= 4.9.  Remove an obsolete comment.  Modify calls to texi2dvi
and texi2pdf to use the '--build-dir' option, so that TeX auxiliary
files and build by-products for a 'foo.texi' input will be placed in
a 'foo.t2d' directory (for texi2dvi) or in a 'foo.t2p' directory (for
texi2pdf).
* automake.in (scan_texinfo_file): Greatly simplify the implementation,
since we don't need anymore to keep track of the TeX auxiliary files and
build by-products to clean.  Drop the '@CLEAN_FILES' part of the return
value.
(handle_texinfo_helper): Adjust the 'scan_texinfo_file()' call to its
new signature.  Append the "work directories" now created by texi2dvi
and texi2pdf invocation to the list of files/directories removed upon
"make mostlyclean".
* lib/am/texinfos.am: Update the cleaning rules (and comments)
accordingly.
* t/txinfo-no-clutter.sh: Minimal adjustment to avoid spurious failures.
* .gitignore: Update.

docs: recursive make considered harmful

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

careful organization in subdirectories, make no (or almost no) use of make
recursion (examples of such packages are GNU bison, GNU cppi, and Automake
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"
for more a more in-depth discussion:

    http://miller.emu.id.au/pmiller/books/rmch/

* doc/automake.texi (Directories): Clarify how a build system based on
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.

12 years agosubdirs: unify rules for "cleaning" and "normal" recursive targets
Stefano Lattarini [Sun, 10 Jun 2012 21:08:07 +0000 (23:08 +0200)]
subdirs: unify rules for "cleaning" and "normal" recursive targets

Before this change, the recursive invocation of cleaning targets in
the $(SUBDIRS) where done in inverse order, i.e., starting from the
last $(SUBDIRS) entry and proceeding towards the first.  According
to the code comments, this was done ...

    ... in an attempt to alleviate a problem that can happen when
    dependencies are enabled.  In this case, the .P file in one
    directory can depend on some automatically generated header
    in an earlier directory.  Since the dependencies are required
    before any target is examined, make bombs.

But this comment does not apply anymore to the current implementation
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.

* NEWS: Update.
* lib/am/subdirs.am ($(RECURSIVE_CLEAN_TARGETS), $(CLEAN_TARGETS)):

* t/subdir-distclean.sh: New test, check that "./configure && make

12 years agoperf: beginning of a performance testsuite
Stefano Lattarini [Tue, 29 May 2012 09:58:02 +0000 (11:58 +0200)]
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
APIs is definitely more difficult, so we leave it for a later step
(an hope we'll take such a step eventually).

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.
