This is just movement and minor reorganization of code; no semantic
change is intended.

(am__TEST_BASES, am__xfail_test_bases): Redefine using that function.
(am__cooked_tests, am__cooked_xfail_tests): Remove as obsolete.
* t/parallel-tests-empty-tests.sh: Don't bother checking the contents
of $(am__cooked_tests) anymore.
[ng] refactor: get rid of am__EXEEXT (automake conditional and %transform)
We can substitute that with a static automake conditional %HANDLE-EXEEXT%
and a make runtime check on the non-emptiness of $(EXEEXT).
* automake.in (preprocess_file): New transform '%HANDLE-EXEEXT%', TRUE
if 'EXEEXT' has been AC_SUBST'd, FALSE otherwise.
(handle_tests): Don't define the transform '%HANDLE-EXEEXT%' anymore
when processing 'check.am': that is now done transparently by the
'preprocess_file' function.
(handle_per_suffix_test): Don't process the transform '%am__EXEEXT%'
anymore when reading 'check2.am'. It's superseded by '%HANDLE-EXEEXT%'
and ...
* lib/am/check2.am [%HANDLE-EXEEXT%]: ... by a make-runtime check that
$(EXEEXT) is not empty.
* m4/init.m4 (AM_INIT_AUTOMAKE): Simplify, taking advantage of the fact
that we don't need the Automake conditional "am__EXEEXT" anymore.
* t/parallel-tests-exeext.sh: Tiny simplification.
[ng] check: big refactoring with semantic changes in parallel-tests support
In this change, we move some further processing related to the parallel
testsuite harness support from Automake runtime to make runtime.
A welcome collateral effect of this is that we are now able to cope
with test scripts whose name ends with several concatenated suffixes.
Another (less welcome) collateral effect of the present change is that
the user now cannot override TEST_LOGS at make runtime anymore:
# This won't work anymore!
make check TESTS_LOGS="foo.log bar.log baz.log"
This admittedly is a small(ish) regression. But it's not a real problem,
since we now explicitly allow *and document* that TESTS can be overridden
at runtime without bothering to add the test suffixes to its entries:
# This will work even if complete names of the tests are (say)
# "foo.test", "bar.test$(EXEEXT)" and "baz$(EXEEXT)".
make check TESTS="foo bar baz"
With such usage, the user don't have to bother knowing which the exact
extensions of each tests are -- which was precisely the only advantage
of overriding TEST_LOGS instead of TESTS.
* NG-NEWS: Update.
* doc/automake.texi: Likewise.
* lib/am/header-vars.am (am__strip_suffixes_0, am__strip_suffixes): New
internal macros ...
* t/internals.tap: ... covered by new checks in this test, and used ...
* lib/am/check.am (am__xfail_test_bases): ... to define this new internal
variable in term of $(am__cooked_xfail_tests) (and thus eventually of
$(XFAIL_TESTS)), and to ...
(am__TEST_BASES): ... (re)define this pre-existing internal variable in
terms of $(am__cooked_tests) (and thus eventually of $(TESTS)), rather
than in terms of $(TEST_LOGS) as was done before.
(am__TEST_RESULTS, am__TEST_LOGS): Define in terms of $(am__TEST_BASES).
(TEST_LOGS): Define to $(am__TEST_LOGS), for backward-compatibility.
($(TEST_SUITE_LOG)): Depend on $(am__TEST_RESULTS) rather than on
$(TEST_LOGS).
(am__check_pre): Use $(am__xfail_test_bases) and new temporary shell
variable $f2, instead of $(am__cooked_xfail_tests) and $f, to decide
whether a test is expected to fail or not.
Fix some imprecise or botched comments since we are at it.
(check-TESTS, recheck): When re-invoking make recursively, override
am__TEST_BASES rather than TEST_LOGS. Relate tweaks.
* automke.in (handle_tests): Pass new transform %HANDLE-EXEEXT% when
including check.am (used for the definitions of am__xfail_test_bases
and am__TEST_BASES). Don't define the TEST_LOGS make variable, nor the
auxiliary make variables am__test_logs1, am__test_logs2, etc. Put
$(am__TEST_LOGS) and $(am__TEST_RESULTS) among the "mostlyclean" files
(rather than "$(TEST_LOGS)" and "$(TEST_LOGS:.log=.trs)" as before).
* t/parallel-tests-concatenated-suffix.sh: New test.
* t/nodeps.sh: Delete, it was causing too much spurious failures.
* t/color2.sh: Avoid a spurious failure by not calling make with
the '-e' flag.
* t/parallel-tests-exeext.sh: Extended to check the user is not
forced to specify the test suffixes nor the $(EXEEXT) suffix
when overriding TESTS on the command line.
* t/check-concurrency-bug9245.sh: Adjust to the new semantics of "no
TEST_LOGS overriding from the command line".
* t/parallel-tests-cmdline-override.sh: Likewise.

* t/parallel-tests-empty-tests.sh: Likewise, and extended to check
that an empty TESTS produces am__cooked_tests, am__TEST_RESULTS,
am__TEST_BASES and am__TEST_LOGS that are empty as well.
* t/parallel-tests.sh: Adjust to the new semantics of "no TEST_LOGS
overriding from the command line". Remove a workaround required only
by HP-UX make. Make some "FIXME"-style comments stick out.
* t/serial-tests.sh: Adjust some checks that grep the Automake
generated Makefile.in.
* t/memoize.tap: Four new tests: three on memoized variables expanded
as arguments of a function call, one on memoized variables expanded
inside other memoized variables. While we are at it, improve brief
description of few existing tests.
Since that bug basically prevents dynamically reassigning to a variable
inside the expansion of the variable itself, we reimplement memoization
by having the memoized variable expanding to an $(if) branching either
to evaluate-and-store in *another* memo variable, else to the value of
that memo variable.
The new workaround works also in the situation that was causing our
previous workaround (as implemented in commit v1.12-217-gd55204f of
2012-05-12, "[ng] vars: implement memoization of make variables (new
'am__memoize' func)") to fail.
Approach suggested by Akim Demaille:
<http://lists.gnu.org/archive/html/automake-ng/2012-05/msg00074.html>
and coded by Stefano Lattarini.
* lib/am/header-vars (am__memoize): Change API and implementation.
(am__memoize_0): Delete, it's not needed anymore.
* t/memoize.tap: Update to new API, also removing checks that makes no
more sense with it.
* t/spy-override.sh: Delete, it's not needed anymore.
When trying to use 'am__memoize' in a non-trivial setup (to optimize
the new form of the parallel-tests harness implemented by the series
http://lists.gnu.org/archive/html/automake-ng/2012-05/msg00015.html),
we stumbled upon that bug again. At this point, it's quite clear that
there is no safe way to safely avoid it, so we'll have to find a way
to enable memoization (that is just an optimization) only with GNU
make >= 3.83 (once that is out).
Here, we just enhance our testsuite to expose the (re)discovered
issue.
* t/memoize.tap: Enhance. The new check fails with GNU make <= 3.82,
and passes with the development version of GNU make (which should
become GNU make 3.83 eventually).
[ng] vars: implement memoization of make variables (new 'am__memoize' func)
This is a preparatory patch that introduces on-demand memoization through
the use of the new internal make function 'am__memoize'. Rationale and a
more detailed explanation follow.
In GNU make (as well as in portable make), "recursive" variables (the
default kind, deriving from assignments like "var = value") have their
value recomputed every time they get expanded.
Most of the time, this has no actual impact on performance, since the
value of a recursive variable is usually either static:
prefix = /usr/local
or only contains references to other recursive variables with static
values:
datadir = ${prefix}/share
In other cases, though, the expansion of the value might require some
non-trivial calculation, or other time-costly operation:
Having such operation performed over and over again (each time the
variable is expanded) might become inefficient, sometimes intolerably
so.
"Immediate" variables (deriving from assignments like "var := value")
are better in this respect, since their definition evaluates the RHS
(Right-Hand Side) immediately, and only once.
But immediate variables have their drawbacks as well.
First of all, the fact that the RHS is expanded immediately means that
the definition of immediate variables is overly sensitive to ordering,
in that any variable referenced in the RHS must be completely defined
before the definition of the affected immediate variable is seen.
Ensuring this might be tricky in general, and even more so with Automake,
which performs non-trivial reordering of make variable.
Also, the RHS of an immediate variable definition is computed
unconditionally, which might be wasteful if only few of the immediate
variables defined in the Makefile are actually going to be used in
a given make invocation.
So we'd like to go for a good middle ground solutions: implementing
memoization for recursive-evaluations variable which are expected to
be expanded often.
Still, we *seem* to have found an implementation that works around the
above issue. Referencing again the examples above, we would now write
something like this:
This API is a little more verbose and clumsy than we'd like, but since
it apparently doesn't tickle the nasty bug referenced above, we'll stick
with it for the moment.
The idea of memoizing recursive variables stemmed from a suggestion
by Akim Demaille:
<http://lists.gnu.org/archive/html/automake-ng/2012-05/msg00062.html>
* lib/am/header-vars.am (am__memoize): New internal function.
(am__memoize_0): Likewise.
* t/memoize.tap: New test, checking $(am__memoize).
* t/spy-override.sh: New test, check that we can use the 'override'
directive as we do in the 'am__memoize' implementation.
* ng/distdir-refactor:
[ng] dist: optimize calculation of list of distributed file
[ng] dist: rename some non-public vars to make clear they are internal
[ng] dist: strip duplicates from dist files at make (not automake) runtime
[ng] dist: simplify VPATH handling
[ng] dist: optimize calculation of list of distributed file
Our implementation of the $(am__uniq) make function is slow as
hell when applied to big lists. Since that function is used to
(re)calculate the list of distributed files, its inefficiency
reflects on *every* run of a Makefile generated by Automake which
distributes a lot of files. For example, a null build of the
Automake tree now takes 20 seconds (!) on my Debian system, while
earlier it was practically instantaneous (less than half a second).
Luckily, the GNU make manual documents that the $(sort) built-in
also strip duplicates from the sorted list. Since we don't care
about the order of the distributed files (or directories thereof),
we can use $(sort ...) instead of $(call am__uniq, ...), and live
happily.
* lib/am/distdir.am (am__dist_files)_: Uniqify content using
'$(sort)', not '$(am__uniq)'.
(am__dist_parent_dirs): Likewise.
Pattern rules are cleaner, safer, and vouched for in the GNU make manual
itself. Supporting them instead of suffix rules will also allow us to
simplify a little the automake script, auxiliary perl modules, and
documentation.
This change introduces a slight backward-incompatibility now, in that
user provided definitions of the SUFFIXES variable or of the .SUFFIXES
target, as well as old-fashioned suffix rules, are now rejected.
Automake-NG still tries to parse and understand suffix-based pattern
rules though, to retain support for user-added file extensions in the
_SOURCES variables (see "Handling new file extensions" in the Automake
manual).
Note that suffix-based pattern rules with dot-less suffix are *not*
supported.
* NG-NEWS: Update.
* doc/automake.texi: Likewise.
* lib/am/footer.am: Declare '.SUFFIXES:' with empty dependencies, to

[ng] rules: can pass deps to &Automake::Rule::define
This change is only useful in view of future changes.

Adjust comments and POD documentation.
* automake.in (file_contents_internal, read_am_file) [/$RULE_PATTERN/]:
Also pass the list of dependencies to the 'Automake::Rule::define'
invocation.
[ng] am: prefer pattern rules over old-fashioned suffix rules
The use of pattern rules is cleaner, safer, and vouched for in the
GNU make manual itself. Moreover, it will allow us to obtain some
simplifications in the automake script and the documentation in
future changes.

[ng] cleanup: remove unused function 'scan_variable_expansions'

"[ng] vars: don't warn about non-POSIX names or GNU make function calls".
[ng] cleanup: use .DEFAULT_GOAL to set the default rule
This change should introduce no semantic change, but allows
a minor simplification in automake.in.
* automake.in ($output_all): Don't define nor use anymore,
its role and function merged with '$output_rules'.
* lib/am/header-vars.am (.DEFAULT_GOAL): Define to 'all'.
* NG-NEWS: Don't list the fact that "support for silent rules is now

[ng] dist: rename some non-public vars to make clear they are internal
The variable $(DISTFILES), $(DIST_COMMON) and $(DIST_SOURCES) have never

This is absolutely not evident from their names, though. So rename them
like this:
* NG-NEWS: Update.
* automake.in: Adjust code and comments.
* lib/am/configure.am, lib/am/data.am, lib/am/java.am, lib/am/lisp.am,
lib/am/python.am, lib/am/scripts.am, lib/am/texi-vers.am: Likewise.
* lib/am/distdir.am: Likewise, and related variable renamings.
And throw in a few improvements to comments since we are at it.
* Several tests: Adjust.
* syntax-checks.mk: Add rules (and supporting variables) verifying
that the obsolete 'DIST*' variables are actually not used anymore.
[ng] dist: strip duplicates from dist files at make (not automake) runtime
We can do this thanks to the new make macros '$(am__uniq)' introduced in
the recent commit 'v1.12-145-g112d08a'.
* automake.in (handle_dist): Don't "uniq"ify the contents of DIST_COMMON
here, but instead ...
* lib/am/distdir.am: ... "uniq"ify the contents of DISTFILES here.
* t/dist-repeated.sh: Remove sanity check checking for a once expected
invariant that is not there anymore now.
* t/distcom4.sh, t/distcom5.sh: Adjust.
Now that we don't need to cater to Sun and Tru64 make, we can simplify
and rationalize our VPATH support in the creation of the distribution
directory. Since we are at it, we clarify some existing comments, add
some new ones, and remove the obsolete ones.
This change has a little collateral effect in that after it the use of
"bare" wildcards in EXTRA_DIST does not work as intended anymore:
# Won't distribute all test files in the builddir anymore.
EXTRA_DIST = *.test
One will have to use the $(wildcard) GNU make builtin instead, as in:
EXTRA_DIST = $(wildcard *.test)
This new limitation is deemed acceptable, especially because "bare"
wildcards suffer of a number of issues and inconsistencies, and their
use is mostly deprecated in favor of the $(wildcard) builtin (refer
to the GNU make manual for more details).
* lib/am/distdir.am (distdir): Extend the comments explaining why, while
filling up the dist directory, we need to check whether any distributed
file already exists in there; in particular, refer to some relevant bug
numbers and past commit IDs. Remove workarounds and hack required to
support automatic VPATH rewrites with Sun and Tru64 make. Refactor the
recipe using ...
(am__dist_files_1, am__dist_files_2, am__dist_files,
am__dist_parent_dirs): This new internal custom GNU make macros.
* NG-NEWS: Document that "bare" wildcards are not supported anymore
in EXTRA_DIST definition.
* t/extra12.sh: Adjust accordingly.
* t/nodep.sh: Remove, it's giving too much false positives to be
usable.
* t/dist-srcdir.sh: New test.

We discourage the use of the non prefixed macro names: M4sugar maps
all the builtins into 'm4_'. Autoconf has been converted to these

them.
Alas, in our init.m4 files, we were still using m4 builtins without
prefixing them with "m4_". Not nice for a package that is one of the
major clients of Autoconf, and an integral part of the GNU Autotools!
Fix the issue.

The new support for Objective C++ (to be added in Automake 1.12.1) can be
simplified if we assume Autoconf version 2.65 or later (2.65 being the
version that introduced support for Objective C++). Since such an Autoconf
version is two and half years old now (and will likely be almost three
years old when Automake 1.13 gets released), requiring it is acceptable.
This will also simplify testing and maintenance of Automake, because we'll
need to test with fewer Autoconf version, and possibly rely on new Autoconf
features.

tests: use append mode to capture parallel make output
This should fix the spurious failure reported in automake bug#11413.
This is due to the fact that the redirected output of parallel make
can racily loose lines. For example, if GNU make (3.82) is run on
a Makefile like this:
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 and Linux 3.3.1. Redirection in append
mode does not suffer of this problem.
See also similar commit 'Release-1-10-280-g6426999' of 2009-03-10,
"Use append mode to capture parallel test output", which tackled a
similar problem for 't/parallel-tests3.sh' and 't/lisp8.sh'.
* t/tap-more.sh: Use append mode for output from "make -j", to avoid
dropped lines.
* t/parallel-tests3.sh, t/lisp8.sh: Enhance comments.
parallel-tests: separate different logs with an empty line
After commit v1.12-21-g5eeb366 "parallel-tests: optimize global log
creation", the log files copied in the global log are not anymore
separated by a blank line, causing unclear output like this:
FAIL: test1
===========
output from test 1
FAIL: test2
===========
output from test 2
where we would want something like this:
FAIL: test1
===========
output from test 1
FAIL: test2
===========
output from test 2
Fix this regression.

silent rules: support for them is always active now
Before this change, support for silent rules was optional and activated
only if the 'silent-rules' option was specified.
The rationale behind that behaviour was that the silent-rules machinery
originally only worked with make implementations supporting nested
variables expansions, which isn't (or wasn't) a POSIX-specified features;
so that packages wanting to be "extra-portable" couldn't use the
silent-rules machinery at all.
But after Paul Eggert's commit 'v1.11-598-g8493499' of 25-12-2011,
"silent-rules: fallback for makes without nested vars" (motivated
by automake bugs #9928 and #10237), Makefiles generated when the
'silent-rules' option is enabled can work also with those make
implementations that don't support nested variables expansion (albeit
the configure-time selected verbosity cannot be overridden at make
runtime in such case).
In light of that, and since silent rules are disabled by default even
when the 'silent-rules' option is given (unless the developer explicitly
makes them enabled by default be calling "AM_SILENT_RULES([yes])" in
configure.ac), we can now have the support for silent rules always
enabled.
The 'silent-rules' option will thus become a no-op, but will reaming a
valid option for the time being, for better backward-compatibility.
A collateral effect of this change is that the use of the 'silent-rules'
option will not anymore automatically disable the warnings in the
'portability-recursive' category.
The present change is basically a backport of the Automake-NG commit
'v1.11d-75-g61ca923' of 19-04-2012, "[ng] silent rules: support for
them is always active now". Stemmed by this thread on the Automake-NG

color-tests: coloring can be forced on non-ANSI terminals as well
Autoconf 2.65 is almost three years old now, so requiring it is
acceptable. Also, the soon-to-appear support for Objective C++
in Automake will be simplified if we can assume that Autoconf
version (which is the one that introduced support for Objective
C++).
* NEWS (Planned future backward-incompatibilities): Automake 1.13
will require Autoconf 2.65 or later.
readme: update INSTALL to latest version from Autoconf
* INSTALL: Updated to the version coming with Autoconf 2.69. This
is warranted now that we use and require that same Autoconf version
in our build system.
color-tests: coloring can be forced on non-ANSI terminals as well
Before this change, colorization of testsuite output was suppressed
whenever the terminal was recognized to be a "dumb" one, incapable
of handling ANSI coloring (i.e., when the environment variable TERM
had a value of "dumb"). This happened even when the AM_COLOR_TESTS
variable was set to a value of "always".
Such a behaviour was suboptimal and slightly confusing; in fact, if
a user wants to force coloring of testsuite output that is being
redirected to a regular file, he should be able to do so even if his
terminal is not capable of handling ANSI colors -- in fact, such
terminal wouldn't be involved with the testsuite output in any way,
so why should it be allowed to influence it?
Thus, we now enable coloring of test output whenever AM_COLOR_TESTS
is set to "always", irrespective of the value of the TERM environment
variable.
* NEWS: Update.
* lib/am/check.am [%?COLOR%] (am__tty_colors): Activate colorization
of testsuite output whenever AM_COLOR_TESTS has the value of "always".
* t/ax/tap-summary-aux.sh: Export the TERM environment variable to
"dumb" when forcing colorization of the testsuite output; this should
*not* prevent such colorization from taking place, and we want to
check that this expectation really holds.

* t/color.sh: Likewise, and adjust some grepping checks.
* t/tap-color.sh: Likewise. Also, remove redundant "make check"
invocation since we are at it.
* t/color2.sh: Likewise, and check that exporting TERM=dumb actually
prevents testsuite output colorization when AM_COLOR_TESTS is unset.
* t/parallel-tests-reset-term.sh: Relax, to prevent it from failing
spuriously due to the new semantic.
