"cout << "string" << endl;" in the test scripts (usages which can be
used in here documents defining C++ sources) are not flagged as uses
of bad delimiters for here documents. This change is not strictly
required for mainline automake, but will help in the Automake-NG

NEWS is updated w.r.t. $(VERSION); given the new way we manage NEWS,
that would cause gratuitous spurious failures.
* HACKING: Update.
tests: use 'parallel-tests' Automake option by default
This will help our transition from 'serial-tests' to 'parallel-tests'
as the default test suite driver enabled by a TESTS assignment in the
input Makefile.am. Note that that change of default will only take
place in master, though.
* defs: Pass the 'parallel-tests' option to the AM_INIT_AUTOMAKE
invocation in the created 'configure.ac' stub, unless the variable
'am_serial_tests' is set to "yes". Don't pay attention anymore to
the 'am_parallel_tests' variable, that's obsolete now.
* defs-static.in: Warn if the 'am_serial_tests' variable is set in the
environment; conversely, don't warn anymore about 'am_parallel_tests'
being set in the environment.
* Makefile.am (AM_TESTS_ENVIRONMENT): Nullify the 'am_serial_tests'
variable instead of the now-obsolete 'am_parallel_tests' one.
* syntax-checks.mk (sc_tests_obsolete_variables): Also warn against
uses of 'am_parallel_tests', which is now deprecated in favor of
'am_serial_tests'. Similarly, if a use of 'parallel_tests' is seen,
suggest using 'am_serial_tests' instead, not 'am_parallel_tests'.
* gen-testsuite-part: Now that we use the 'parallel-tests' by default
in our tests, we need to completely change the logic and semantics of
generation of sibling tests for those tests that check the Automake
generated testsuite harness itself. Do that, and give a complete
explanation of the new logic and semantics in the relevant comments.
* t/README: Update.
* Lots of test cases: Adjust.
doc: fix location of Automake's own test-suite.log file
* doc/automake.texi (Reporting Bugs): The global testsuite log of
Automake is now (basically since we have removed make recursion from
the Automake's build system) saved in the file 'test-suite.log', not

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.

The comments in 'lib/autoconf/autoconf.m4' from Autoconf 2.69 read:

names too. But users may still depend upon these, so reestablish
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.

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.

parallel-tests: separate different logs with an empty line
After commit v1.12-21-g5eeb366 "parallel-tests: optimize global log

separated by a blank line, causing unclear output like this:
FAIL: test1

FAIL: test2

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".

fixup: avoid unconditional re-bootstrapping on "make dist"
Since our 'bootstrap' script is distributed, the 'distdir' target depends
on it. But in our GNUmakefile, we also have a 'bootstrap' target declared
.PHONY, which when called re-bootstrap the Automake distribution. Thus,
whenever we run "make dist", GNU make sees it must remake the 'bootstrap'
target (as it is a dependency of the 'distdir' target), and thus ends up
re-bootstrapping all the package (because of the .PHONY 'bootstrap' target
in GNUmakefile).
We fix this issue by renaming our bootstrap script to 'bootstrap.sh'.
build: ensure release year in copyright notice is up-to-date

initialized from the value substituted for '@RELEASE_YEAR@'.
(@EXPORT): Add it.
* automake.in, aclocal.in: Use '$RELEASE_YEAR' (which will be
substituted at make time) instead of hard-coding the release
year. This should ensure the copyright range in the version
message and in the generated files (Makefile.in and aclocal.m4)
are automatically kept up-to-date.
* bootstrap (dosubst): Update, also substitute '@RELEASE_YEAR@'.
* THANKS: Use spaces, not tabs, to separate a reporter's name from
his e-mail address. Also, increase such spacing, to allow a more
consistent formatting with longer names.
readme: explicitly state we use ranges in copyright years
Reported by Jack Kelly in automake bug#11356.
* README: Explicitly state we use ranges in copyright years; this is
mandated by the GNU Coding Standards for each package that wants to
actually use ranges in copyright years.
Dependencies in the Automake build system are not completely specified
(see for example the commit log of recent commit 'v1.12-10-gab14841',
"build: avoid too greedy rebuilds in the testsuite"). In fact, some of
them cannot even be; for example, Makefile is generated at configure
time from Makefile.in, which should be regenerated by our bleeding-edge
automake script, which is generated by out Makefile -- specifying the
complete chain of dependencies here would bring to a circular dependency
issue.
For this reason, before testing or deploying a change, we are often
forced to perform a full re-bootstrap of the Automake package, to ensure
all our files are actually up-to-date. Until now, this has to be done
manually, thus causing wasted keystrokes and more possibilities of error.
With this change, we introduce a new 'bootstrap' make target to
automatize all the (easy) steps of this re-bootstrapping (plus some
minor bells & whistles since we are at it).
* GNUmakefile: Rewrite to allow an easy bootstrapping and clean rebuild
of the whole package, in particular with the help of ...

message. Ditto for the copyright notice in the generated Makefile.in
or aclocal.m4 files; and for those, since we are at it, prefer using
a range for copyright years, rather than listing each copyright year
individually.
maint: don't use "union" merge driver for NEWS anymore
The use of the "union" merge driver to avoid conflicts in NEWS has
proven to be problematic, as it often silently produced mis-merges
(instead of spurious conflicts, but a spurious conflict is better
than a mis-merge). Also, our new branching policy (see automake
bug#11153 for a description) should greatly mitigate the problem of
merge conflicts in NEWS. For further discussion, see:
<http://lists.gnu.org/archive/html/automake-patches/2012-04/msg00148.html>
The autogenerated makefile fragment 't/testsuite-part.am' used to depend
on the list of *all* the hand-written files. This was technically correct,
since that makefile fragment was (and still is) generated by the script
'gen-testsuite-part', which scans all the hand-written files to detect
implicit dependencies and to decide for which tests a further wrapper test
should be generated.
However, the presence of such a dependency implied that, whenever *any*
test case was modified (no matter how slightly), the 't/testsuite-part.am'
file was rebuilt, and since that is included by our 'Makefile.am', the
'Makefile.in' file was rebuilt as well by automake. In order to do so,
automake scanned our 'configure.ac' file, which requires the latest
Autoconf version (2.69 at the time of writing), and the casual user can
easily lack that on his machine (and that should be allowed, as automake
currently supports any autoconf version >= 2.62).
The described situation could hinder in-field testing or debugging by
users (even experienced ones) that are not automake developers; see for
example automake bug#11347.
So we drop the explicit dependency of 't/testsuite-part.am' on the
hand-written test cases. (As an aside, note that this has already
been done in Automake-NG, albeit for other reasons; see the commit
'v1.11b-129-g1690aca' of 2012-04-23, "[ng] build: define $(TESTS)
through a wildcard").
This is not a serious regression in the faithfulness of the Automake
build systems, since it unfortunately already had several undeclared
dependencies; e.g., 'Makefile.in' should depend on the automake script,
and 'aclocal.m4' should depend on the aclocal script (but this isn't
possible, as it would mean that distributed files depend on ones generated
at make time). Similarly, 'Makefile.in' should depend on some of the
'lib/am/*.am' files, but does not.
Currently, the workaround to get a faithful and correct rebuild is to run
./bootstrap && ./config.status --recheck && make clean all
and the present commit does not change that.
* Makefile.am ($(srcdir)/t/testsuite-part.am): Don't depend on
't/list-of-tests.mk' nor on '$(handwritten_TESTS)' anymore.
($(generated_TESTS)): Likewise, and don't depend on 'Makefile.am'
either.
The <cstdio> header from Xcode-4.3.2 on Mac OS X 10.7.3 declares a 'isatty'
function with C++ linkage, that conflicts with our dummy definition of the
same function, which in turn is required to work around the absence of the
unistd.h header on MinGW (see commit 'v1.11-2138-gfeea090' of 11-04-2012).
So we tweak the affected tests to work around this new problem as well.
This fixes automake bug#11345.
* t/lex-clean-cxx.sh ($required): Since we are at it, add an explicit
'c++' requirement.
* t/lex-depend-cxx.sh ($required): Likewise.
(my-hdr.hxx): Don't include <cstdio>. The "using namespace" directive
should still be enough to ensure the content of this header is not valid
C, albeit being of course valid C++.
Fix unrelated typos in comments.
(joe.ll): Adjust, by removing the call to 'printf'.
* THANKS: Add entry for reporter "Adam Mercer".
It is only from version 2.69 that the 'AC_PROG_FC' macro has started to
set the '$GFC' variable to "yes" if the selected Fortran compiler is a
GNU compiler. Since we use this variable in our configure.ac, we better
require autoconf 2.69 explicitly.
build: don't require minimal automake version in AM_INIT_AUTOMAKE
* configure.ac (AM_INIT_AUTOMAKE): Don't explicitly require a minimal
automake version number. Since the Automake build system is only meant
to work with the bleeding-edge automake, that requirement was redundant
and misleading.
* configure.ac (AC_INIT): Bump version number to 1.12.
* NEWS: Likewise.
* m4/amversion.m4 (AM_AUTOMAKE_VERSION): Likewise (autoupdated
by ./bootstrap).
coverage: test the internal $(am__relativize) variable
This new coverage might turn out be useful for the planned changes
in Automake-NG. Even if it eventually doesn't, we gen an improved
testsuite exposure of some non-trivial internals, so it's always a
win for us.
* t/relativize.tap: New test.
* t/list-of-tests.mk: Add it.
On at least OpenSUSE 12.1, "make install" will install libraries in
the '${prefix}/lib64' directory by default. This is due to the
$CONFIG_SITE set by /etc/profile.d/site.sh, which sets a libdir
that ends in '/lib64' rather than '/lib' if it finds that the compiler
is generating 64-bit code. This behaviour was causing some spurious
failures in our testsuite. Fix them.
* t/posixsubst-libraries.sh: Assume the libraries are installed in
'$(libdir)' rather than in '$(prefix)/lib'.
* t/posixsubst-ltlibraries.sh: Likewise.
* t/posixsubst-scripts.sh: Similarly, don't assume that '$(bindir)',
'$(sbindir)' and '$(libexedir)' always defaults to respectively
'$(prefix)/bin', '$(prefix)/sbin' and '$(prefix)/libexec'.
* t/transform3.test: Likewise.
* t/lex-libobj.sh: We used to pass LEXLIB='-L /lib' to the ./configure
invocation, to prevent it from explicitly searching for a "lex library".
But the linker on MacOS X 10.5 apparently chokes on that:
cc -g -O2 -o foo foo.o -L /lib yywrap.o
ld: file not found: /lib
collect2: ld returned 1 exit status
So, we now instead pass LEXLIB=' ', which being non-empty is enough
to prevent the search of a "lex library". And since we are at it,
enhance comments on this non-obvious usage.

vala: configure exit with status 77, not 1, if valac version is too old
From a report by Bruno Haible in automake bug#1193. This change should
also automatically avoid spurious testsuite failures with older vala
versions.
* m4/vala.m4 (AM_PROG_VALAC): Exit with status 77, rather than 1, if
the Vala compiler found older than the minimal required version (if
any). This is more consistent with what is done by other macros like
AM_PROG_UPC or AC_PROG_CC.
* NEWS: Update.
* t/vala-headers.sh: Adjust, so that the test is only skipped of the
vala compiler is too old or the required PKG_CHECK_MODULES third-party
macro is not found by aclocal, and not if a generic error happens in
the configure script.
* t/vala-libs.sh: Likewise.
* t/vala2.sh: Likewise.
* t/vala3.sh: Likewise.
* t/vala5.sh: Likewise.
* t/vala-vpath.sh: Likewise (but don't check for the potential error
with PKG_CHECK_MODULES, as that macro is not used in any way here).
* t/vala4.sh: Adjust, to avoid the new semantic causing this test to
skip instead of failing.
This is a pure refactoring, with no intended functional or semantic
changes. It breaks up an overly-long function in three smaller
sub-functions. This change will very especially useful for the work
on Automake-NG.
* lib/Automake/Rule.pm (define): Move quite a lot of code out, into ...
(_rule_defn_with_exeext_awareness, _maybe_warn_about_duplicated_target,
_conditionals_for_rule): ... these new subroutines.
automake: refactor pre-processing of makefile fragments
This change will provide the automake script with a new function that
reads in a Makefile fragment *without* performing Automake ad-hoc parsing,
but only the pre-processing step, i.e., removal of '##' comments and
substitution of tokens like '%SUBDIRS%', '%?LIBTOOL%' or '?GENENRIC?'.
This will very likely be useful for the work on Automake-NG.
This is a pure refactoring, with no intended functional or semantic
changes.
* automake.in (preprocess_file): New function, extracted ...
(make_paragraphs): ... from here.
Autoconf 2.13 is definitely obsolete today, so giving hints or caveats
about it in the Automake documentation is not only obsolescent, but
also counter-productive, as it suggests that autoconf 2.13 is still
relevant.
* doc/automake.texi: Adjust. Related rewordings. Since we are at it,
prefer using a more modern autoconf version number (2.68 instead of 2.57)
in an example showing how to correctly use 'AC_PREREQ' in third-party
.m4 files.
tests: fix spurious failure with non-ANSI terminals
* t/ax/tap-summary-aux.sh: When checking colored testsuite output,
be sure to export the TERM variable to the value "ansi"; otherwise
the automake testsuite driver will not display colored output, not
even if AM_COLOR_TESTS is exported to "always". Failure revealed
by NixOS Hydra.
