        gitlog-to-changelog: new auxiliary script, synced from gnulib

        We have plans to stop maintaining a version-controlled ChangeLog
        file in the Automake repository, and instead begin to generate it
        automatically from the git log messages.  To do so, we will use
        the `gitlog-to-changelog' script from gnulib.

        * lib/gitlog-to-changelog: New, synced from gnulib.
        * Makefile.am (fetch): Fetch and sync it.
        * lib/Makefile.am (EXTRA_DIST): Distribute it.

        docs: "aclocal --install -I /abs/dir" actually copies files

        This change is for automake bug#8407.

        In the past, there had been some debate and confusion about
        whether "aclocal --install" should copy third-party .m4 files
        in the first directory passed to the `-I' option even when
        such directory was given as an absolute path, or whether it
        was better to do so only for directories specified with a
        relative path.

        The rationale for this latter behaviour was that, before the
        existence of the `ACLOCAL_PATH' variable, the only way (a poor
        way, I might add) for a common user to extend the search path
        of a system-wide installation of aclocal was to export something
        like ACLOCAL="aclocal -I /my/extra/macros" in the environment.
        Today, the correct way to proceed is undoubtedly through the
        use of ACLOCAL_PATH, so we can settle the question once and for
        all, and start verifying the correct behaviour of `-I' with a
        new test.

        * tests/aclocal-install-absdir.test: New test.
        * tests/Makefile.am (TESTS): Add it.
        * doc/automake.texi (aclocal Options): Be more explicit about
        this part of `--install' semantics.

        docs: fix node names for automake and aclocal invocations

        With the older node names, an "info automake" command issued
        from the command line would have opened the node about the
        invocation of the automake program, rather than the Top node
        of the automake documentation.  To invoke the Top node, one
        had to issue the command "info Automake" instead (note the
        different capitalization).  This was suboptimal, and certainly
        confusing.

        With this change, "info automake" will open the Top node of the
        automake documentation; to access the nodes about the invocation
        of the automake and aclocal program, one has now to issue "info
        automake-invocation" and "info aclocal-invocation" respectively.

        This change fixes automake bug#8071.

        See also commits `v2.61a-22-ge9215d1' and `v2.61a-72-g8c07b48' in
        the autoconf git repository, which tackled a similar issue.

        * doc/automake.texi (@direntry): Rename nodes `aclocal' and
        `automake' to `aclocal-invocation' and `automake-invocation'
        respectively.
        * NEWS: Update.

        tests: tweak tests on silent-rules for makes without nested vars
        * tests/silent-nested-vars.test: Define $MAKE to `./mymake' in
        the environment, so that it will be automatically picked up by
        configure.  Related tweaks and simplifications.
        Remove the checks verifying that silent rules are respected also
        when the 'subdir-objects' option is set, the checks testing the
        old syntax for user-defined silent rules, and the tests using
        the default $MAKE programs: they are redundant w.r.t. other test
        cases.  Related simplifications.
        Remove the temporary files used in a sanity check as soon as they
        are not needed anymore.
        Do not capture also the standard error of configure: we only want
        to grep its standard output.
        Consistently use `stdout' for the name of files where to save the
        standard output captured from make and configure, for consistency
        with other tests.
        Make grepping of configure output and of the generated Makefile
        stricter.
        Improve and tweak the `mymake' script a little.
        * tests/silent6.test: Make grepping of make stdout slightly
        stricter.  After having configured with silent rules disabled,
        try to force the use silent rules with `make V=1'.

        silent-rules: fallback for makes without nested vars

        This fixes two problems reported for Automake (Bug#9928, Bug#10237)
        and is in response to a bug report for building coreutils on HP
        NonStop OS (Bug#10234).  The problem is that HP NonStop 'make'
        treats a line like "AM_V_CC = $(am__v_CC_$(V))" as one that
        expands a macro with the funny name am__v_CC_$(V instead of the
        desired name am__v_CC_1 or am__v_CC_0, and since the funny macro
        is not defined the line is equivalent to "AM_V_CC = )"; this
        inserts a stray ")" when $(AM_V_CC) is used, which eventually
        causes 'make' to fail.

        The basic idea is that instead of generating Makefile.in lines like
        "AM_V_CC = $(am__v_CC_$(V))", we generate
        "AM_V_CC = $(am__v_CC_@AM_V@)".  We then AC_SUBST $(V) for @AM_V@
        in the usual case where `make' supports nested variables,
        and substitute 1 (or 0) otherwise.  Similarly for usages like
        $(am__v_CC_$(AM_DEFAULT_VERBOSITY)).

        With this change, make implementations that doesn't grasp nested
        variable expansions will still be able to run Makefiles generated
        using the silent-rules option.  They won't allow the user to
        override the make verbosity at runtime through redefinition of
        $(V) (as in "make V=0"); but this is still an improvement over not
        being able to work at all.

        * NEWS: Document this.
        * automake.in (define_verbose_var): When defining the variables,
        use @AM_V@ rather than $(V), and use @AM_DEFAULT_V@ rather than
        $(AM_DEFAULT_VERBOSITY).
        * doc/automake.texi (Automake silent-rules Option): Explain new system.
        * m4/silent.m4 (AM_SILENT_RULES): Check whether `make' supports
        nested variables, and substitute AM_V and AM_DEFAULT_V accordingly.
        * tests/silent-nested-vars.test: New test.
        * tests/Makefile.am (TESTS): Add it.

        contents merged into ...
        * .gitignore: ... this top-level file.  Since we are at it, improve
        it by anchoring files where it makes sense.

        tests: one more fixlet for gettext macros requirement
        * tests/gettext-macros.test (configure.in): Add calls to
        AC_INIT and AC_PROG_CC, to avoid a spurious failure in the
        later aclocal invocation.
        Luckily, this wart wasn't causing any spurious SKIP or FAIL,
        but only the redundant addition to the `-Wno-syntax' option
        to some aclocal invocations in the gettext tests.

        tests: fix handling of gettext macros requirement

        The code introduced in the earlier change `v1.11-581-gb7d67d5'
        and aimed at automatically fetching all the .m4 files provided by
        gettext has proven inadequate, since it hasn't managed to truly
        and always get *all* the required .m4 files.  For example, it has
        failed to fetch the file `intldir.m4' (present in gettext 0.18.1,
        and where the macro `AM_GNU_GETTEXT_INTL_SUBDIR' is defined),
        which in turn has caused spurious SKIPs of at least the test
        `gettext3.test'.

        The reason for this debacle is that autopoint looks at the version
        specified in AM_GNU_GETTEXT_VERSION to decide which version of the
        gettext infrastructure to bring in; since we were unconditionally
        specifying the older 0.10.35 version, the newer `.m4' files weren't
        brought in.

        * tests/gettext-macros.test: In AM_GNU_GETTEXT_VERSION, instead
        of unconditionally specifying the older 0.10.35 version, specify
        the version of the available `gettextize' or `autopoint' program,
        dynamically extracted with the help of ...
        (extract_program_version):... this new function, and saved ...
        ($autopoint_version): ... in this new variable.

        tests: fix failure due to debugging code forgotten into a test
        * tests/missing-tar.test: Don't ever call the `missing' script
        with `sh -x'; this was used for debugging, but an instance of
        it slipped into the committed test case.  Bug revealed by a
        failure on a Solaris 10 system with GNU tar installed as `gtar'.

2011-12-23  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tests: avoid spurious failure of libtool and gettext tests

        On Solaris 10 (and presumably earlier), /bin/sh trips up on
        here-documents that contains a command substitution *and* are
        fed to a shell function:

          # All as expected.
          $ cat <<END
          `pwd`
          END
          /home/stefano
          $ echo status = $?
          status = 0

          # An apparently innocuous function ...
          $ kitty () { cat; }
          # ... but hilarity ensues!
          $ kitty <<END
          `pwd`
          END
          /tmp/sh137723: cannot open
          $ echo status = $?
          status = 1

        We need to work around this misbehaviour in a couple of our
        tests (whose failures where causing cascading failures in a
        lot of other tests).

        * tests/gettext-macros.test: Avoid the use of command substitution
        in a here-document passed to the `indent' function, by using the
        `echo' builtin instead.
        * tests/libtool-macros.test: Likewise.

        hacking: distribute it, and mention it in the ChangeLog
        Not distributing the HACKING file might make it more difficult,
        for some random curious user, to get informed about or interested

        regex: deprecate the obsolete macro AM_WITH_REGEX
        This is a backport of commit v1.11-433-g37b0aee.
        Today, practically nobody uses the GNU rx library, which, according
        to its own website <http://www.gnu.org/software/rx/rx.html>, has
        been "decommissioned".  Consequently, the automake-provided macro
        AM_WITH_REGEX is not used nor required anymore.  Deprecate it, so
        that it will be possible to safely remove it in the next major
        automake version.
        * m4/regex.m4 (AM_WITH_REGEX): Give a warning of the class
        `obsolete' when this macro is used.
        * doc/automake.texi (Public Macros): Move description of
        `AM_WITH_REGEX' from here ...
        (Obsolete Macros): ... to here, and declare it as obsolete
        and "to be removed in a future version".
        * tests/regex-obsolete.test: New test.

        maint: distribute .xz tarballs, not .bz2 ones
        Many GNU packages are moving towards xz-compressed tarballs, so
        let's follow suit, by dropping the creation and distribution of
        a bzip2-compressed tarball and switching to xz instead.
        For compatibility and safeness, we will continue to create and
        distribute a gzip-compressed tarball as well.
        * configure.ac (AM_INIT_AUTOMAKE): Drop `dist-bzip2', add

        tests: better handling of gettext and libtool requirements

        This change fixes automake bug#9807.

        Before this change, the automake testsuite only looked for the
        `.m4' files containing libtool and gettext macros definitions in
        the directory `${prefix}/share/aclocal' (and in the directories
        specified by the `dirlist' file in there, if any), where ${prefix}
        was the configure-time automake installation prefix (defaulting
        to `/usr/local').

        This approach had various shortcomings and disadvantages.  Let's
        briefly describe the three major ones.

        First, on most GNU/Linux systems, a libtool or gettext installed
        from distro-provided packages (e.g., by dpkg on Debian/Ubuntu, or
        by rmp on RedHat/Fedora) would have `/usr', not `/usr/local', as
        its ${prefix}; so, trying to run the automake testsuite with a
        simple "./configure && make && make check" would have failed to
        execute the libtool and gettext tests on most GNU/Linux distros.
        It's true that it was quite easy to work around this issue, by
        creating a proper `/usr/local/share/aclocal/dirlist' file with
        an entry pointing to `/usr/share/aclocal' (a workaround in fact
        used by most automake developers); but the typical user wasn't
        aware of the necessity of this trick, so the libtool and gettext
        tests was usually skipped on testsuite runs "in the wild", thus
        needlessly reducing coverage.

        Second, the older testsuite behaviour made more difficult for
        the developers to run the testsuite with non-default libtool or
        gettext.  For example, assume the developer is working on a system
        that has a default libtool version 1.5 installed in the /usr/local
        hierarchy; to improve coverage, the developer installs also a more
        modern libtool version, say 2.4, in its home directory, let's say
        in ~/libtool-2.4; he then tries to run the automake testsuite with
        this more modern libtool by doing an (apparently) simple:
          $ PATH=$HOME/libtool-2.4:$PATH make check
        But the automake testsuite would still look for libtool macros in
        /usr/local/share/aclocal, not in ~/libtool-2.4/share/aclocal, so
        the wrong version of the macros would be picked up, and the tests
        would either fail spuriously or (which would be worse) pass without
        truly covering the libtool version the developers was thinking to
        be testing with.
        Worse again, the automake testsuite would *unconditionally* look
        for libtool macros in /usr/local/share/aclocal, so even something
        like:
          $ export ACLOCAL_PATH=$HOME/libtool-2.4/share/aclocal
          $ PATH=$HOME/libtool-2.4:$PATH make check
        wouldn't work.

        Third and last, during a "make distcheck", automake is configured
        with a ${prefix} pointing to a proper subdirectory of the build
        directory (usually `pwd`/_inst), which gets created on-the-fly;
        in this case, with the old approach, the automake testsuite never
        found the libtool and gettext macro files, ans so the libtool and
        gettext tests was *always* skipped in a "make distcheck".

        * tests/libtool-macros.test: New helper test, looking (with the
        help of the `libtoolize' script) for libtool macro files required
        by most libtool tests, and making them easily accessible.
        * tests/gettext-macros.test: New helper test, looking (with the
        help of the `libtoolize' script) for libtool macro files required
        by most libtool tests, and making them easily accessible.
        * tests/defs.in: Update to make it rely on the results and setups
        of `libtool-macros.test' and `gettext-macros.test'.
        * tests/Makefile.am: Declare dependency of all the logs of libtool
        tests from `libtool-macros.log', and all the logs of gettext tests
        from `gettext-macros.log'.
        (TESTS): Add the new tests.

        tests: report useful system information in 'test-suite.log'
        It has already happened various times that a user has run the
        automake testsuite, experienced a failure, read the messages
        telling him "See tests/test-suite.log" and "Please report to
        bug-automake@gnu.org", and done exactly that -- sending us only
        the contents of `tests/test-suite.log', which are usually not
        enough to start debugging the reported failure.  So we have to
        ask him for more details, and usually also for the `config.log'
        file generated by configure.  It's time to fix this recurring
        feedback inefficiency.  We do so by creating a dummy test case
        that takes care of copying the contents of `config.log', plus
        other useful system information, in the final `test-suite.log'.
        * tests/get-sysconf.test: New test, gathering system information
        and then always terminating with a SKIP, so that its output gets
        copied in `test-suite.log'.
        * tests/Makefile.am (TESTS): Add it.

        maint: snapshots from `maint' are still development snapshots
        The maintenance-oriented development line in the `maint' branch,
        while being usually pretty stable and 99% backward-compatible,
        is not always right off production-quality; but until now, the
        Automake package version declared in configure.ac hid this fact,
        since it appeared to be the version of a stable release (e.g.,
        11.1).  Fix this.

        devel: help in comparing Makefile.in from different commits
        Now that the generated Makefile.in, configure and aclocal.m4 files
        are no longer committed in Automake's git repository, a simple
        "git diff" or "git log" no longer shows if and how a change in
        Automake results in changes to the Makefile.in files and/or
        configure script of its own build system.  Still, the ability to
        peek so easily at such differences has proved itself quite useful
        in the past, often revealing inconsistencies and blunders, and
        sometimes even bugs; so it would be a pity to lose that altogether.
        With this change, we add a new maintainer recipe that re-introduces
        much of that capability, by generating and comparing on the fly the
        Makefile.in, configure and aclocal.m4 derived from two arbitrary
        commits of the Automake repository.
        * Makefile.am (autodiffs, compare-autodiffs): New phony targets.

        repo: don't commit generated files in the git repository anymore
        It has been quite some time since autoconf and libtool have stopped
        committing the generated autotools files in their git repositories,
        with no significant ill effects we're aware of.  It's true that the
        autoconf bootstrap process has now the minor annoyance that a
        pre-installed autoconf is required to complete it; but luckily
        automake will not have a similar annoyance, since our bootstrap
        script take care, through some hoops, to use the very automake and
        aclocal versions from the current git checkout to generate the
        required aclocal.m4 and Makefile.in files.  In fact, this has been
        a necessity also in the past, because automake has been known to
        use in its own build system new development features that hadn't
        been present in any previously released automake distribution.
        * .gitignore: Ignore configure, aclocal.m4, and all the
        Makefile.in files.
        * configure.ac (AC_PREREQ): New macro call, to require the
        latest autoconf (2.68 for the moment).

        missing: don't try to re-run tar with a munged command line
        * lib/missing: If the default `tar' program fails with the given
        arguments, and GNU tar is not available, don't try to re-run the
        default `tar' with a munged command line (e.g., ditching possibly
        unportable options), as that could be subtly alter the intended
        semantics (and maybe even create a somewhat corrupted tarball).
        Also, it's worth noting that the main purpose of the `missing'
        script is to allow a non-developer to build the package in the
        face of slightly-skewed timestamps, not to provide wrappers for
        all the maintainer tools -- so we don't have to try too hard
        when `missing' is just called to wrap `tar'.
        * tests/missing-tar.test: New test.

        dist-xz, dist-bzip2: don't hard-code -9, honor envvar settings
        Before the present change, automake-generated `dist-xz' rule used
        a hard-coded `xz -9'.  That was a problem because on this front,
        xz differs from gzip and bzip2.  While the latter two don't incur
        any run-time decompression penalty for using a higher compression
        level, specifying -9 with xz imposes a potentially fatal virtual
        memory requirement on any client that wants to decompress your
        tar.xz file.
        People have complained that a tarball compressed with -9 cannot
        be uncompressed in a low-memory environment (wrt-based embedded).
        Hence, instead of defaulting to -9, which is useful only for very
        large tarballs, it defaults to -e (equivalent to -6e).  This
        limits the default memory requirements imposed on decompressors,
        yet still gives very good compression ratios.
        * lib/am/distdir.am (dist-xz): Do not hard-code xz's -9: that made
        it impossible to override.  Actually don't default to -9, either,
        since that induced inordinately large virtual memory usage when
        merely decompressing.  Instead, use its XZ_OPT envvar, defaulting
        to -e if not defined.  Suggested by Lasse Collin.
        (dist, dist-all) [?XZ?]: Likewise
        (dist-bzip2): Similarly, do not hard-code -9, but do continue to
        use -9 by default.  Honor the BZIP2 envvar.

        tests: fix spurious failures due to missing 'yywrap()' function

        The AC_PROG_LEX Autoconf macro does not diagnose a failure to find
        the "lex library" expected to provide a `yywrap' function (function
        which is required to link most lex-generated programs).  On the
        contrary, when all the link attempts (i.e., with `-ll' and `-lfl')
        fail, configure declares that no lex library is needed, and simply
        proceeds with the configuration process -- only for the build to
        possibly fail later, at make time.

        This behaviour is intended; the Autoconf manual reads:
         ``You are encouraged to use Flex in your sources, since it is
           both more pleasant to use than plain Lex and the C source it
           produces is portable.  In order to ensure portability, however,
           you must either provide a function `yywrap' or, if you don't use
           it (e.g., your scanner has no `#include'-like feature), simply
           include a `%noyywrap' statement in the scanner's source.''

        This AC_PROG_LEX behaviour is causing some spurious failures of
        the Automake testsuite in environments which lack a proper library
        providing `yywrap' (this happens for example on Fedora-based
        systems).   The proper workaround is to simply provide a fall-back
        implementation of `yywrap' in our lexers.

        See also partially-overlapping commit `v1.11-871-geb147a1' (from
        the 'testsuite-work' branch), which was motivated by similar
        spurious failures experienced when cross-compiling.

        maint-mode: fix botched configure messages
        This change fixes automake bug#9890.
        * m4/maintainer.m4 (AM_MAINTAINER_MODE): Fix the "checking ..."
        configure message related to the enabling/disabling of maintainer
        mode.
        * tests/help-maintainer.test: Renamed ...
        * tests/maintmode-configure-msg.test: ... to this, and extended
        to cover the fixed bug.  Also, since we are at it, make grepping
        of configure help screens stricter, and throw in some few other
        changes to reduce code duplication and enhance readability.
        * tests/Makefile.am (TESTS): Update.
        * THANKS: Update with Zack's new e-mail address.

        info: allow user to inhibit creation/update of '${infodir}/dir'
        With this change, we allow the user to request the install-info
        rules not to update the `${infodir}/dir' file, by setting the
        environment variable `AM_UPDATE_INFO_DIR' to the value "no".
        This is especially useful to distro packagers, and is a definite
        improvement over our previous hack of looking whether the
        `install-info' program was the Debian or GNU version -- hack
        which had been silently broken with recent versions of debian
        install-info BTW (probably since dpkg 1.15.4, 2009-09-06).
        This change fixes automake bug#9773.  See also Debian Bug#543992.
        * lib/am/texinfos.am: Don't look anymore at the output of
        `install-info --version' to decide whether to use it to update
        the `${infodir}/dir' or not; instead, honour the environment
        variable `AM_UPDATE_INFO_DIR'.
        * tests/install-info-dir.test: New test.
        * tests/Makefile.am (TESTS): Add it.
        * tests/defs: Also unset `AM_UPDATE_INFO_DIR', to avoid unwanted
        interferences from the environment.
        * doc/automake.texi (Texinfo): Update.
        * NEWS: Likewise.
        * THANKS: Likewise.

        deps: partially revert commit `v1.11-512-geeee551'
        This change partly reverts commit "Create subdirs for generated
        sources even when not dep tracking", of 2011-04-02.
        That commit had caused the bugs #8485 and #8526.  Since we are
        nearing the bug-fixing automake release 1.11.2, the safest policy
        at the moment is to just revert the problematic hunks: an older,
        known bug is better than a regression.
        * automake.in (handle_single_transform): Don't add a dirstamp
        dependency, even when $object is derived and lands in a subdir.
        * tests/Makefile.am (XFAIL_TESTS): Add lex-subobj-nodep.test,
        remove yacc-dist-nobuild-subdir.test.

        dejagnu: allow the package developer to extend site.exp

        $(EXTRA_DEJAGNU_SITE_CONFIG), if any.  Append their contents to
        the generated site.exp (still preserving user edits).

2010-12-10  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Extend and improve tests on DejaGnu support.
        * tests/dejagnu.test: Do not create useless dummy test script.
        Add trailing `:' command.  In heading comments, add reference
        to ...
        * tests/check12.test: ... this new "semantic" test, covering
        concurrent use of dejagnu tests, simple tests and `check-local'
        target.
        * tests/dejagnu2.test: Make test more reliable, by avoid weak
        grepping of make output.  Prefer `cat' over `echo' to append
        to configure.in.  Quote literal dots in grep regexps.  Prefer
        `grep -c ...' over `grep ... | wc -l'.  Make grepping of
        automake stderr slightly stricter.  Add trailing `:' command.
        * tests/dejagnu3.test: Prefer `cat' over `echo' to append to
        configure.in.  Check stderr of expected-to-fail "make" call.
        Remove extra blank lines from Makefile.am.
        * tests/dejagnu4.test: Prefer `cat' over `echo' to append to
        configure.in.  Prefer `mv -f' over plain `mv' when the target
        file already exists.  Avoid extra mkdir calls by creating more
        directories at once.  Better use of blank lines.  Check that
        the `*.log' and `*.sum' files are created by runtest also when
        "make check" fails.
        * tests/dejagnu7.test: Prefer `cat' over `echo' to append to
        configure.in.  Better use of blank lines.  Add a trailing `:'
        command.
        * tests/dejagnu6.test: Likewise, and give the dejagnu test a
        more descriptive name.
        * tests/dejagnu5.test: Likewise.  Also, simply define package
        name to `$me' rather than using a non-obvious sed script to
        extract it from `AC_INIT', and write the Makefile.am with only
        one command.
        * tests/Makefile.am (TESTS): Updated.

        checking that $(YLWRAP) is defined and installed properly when
        ylwrap is in a default auxdir found in a parent package ...
        * tests/subpkg-yacc.test: ... into this new test, which carefully
        avoids to trigger the known bug#7884 (combo FreeBSD make plus Yacc
        plus VPATH build).

        tests: avoid spurious failure in 'parallel-tests3.test'
        This fixes automake bug#8788.
        * tests/parallel-tests3.test: To ensure that the serial run of
        the dummy testsuite is still ongoing when the parallel run has
        terminated, use `kill -0', not a bare `kill'.  This will prevent
        a testsuite crash on NetBSD 5.1, and a testsuite hang on FreeBSD
        8.2.  Also, since we are at it, try harder to avoid possible
        hangs of the script in other unusual situations.

        tests: fix spurious failures with "chatty" make implementations
        * tests/distcheck-missing-m4.test: On failure, some make
        implementations (such as Solaris make) print the whole failed
        recipe on standard output.  This was causing a spurious failure
        in the checks grepping the output from make.  Work around this.
        * tests/distcheck-outdated-m4.test: Likewise.

2011-10-20  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tests: fix spurious failure on fast machines
        * tests/aclocal-path-precedence.test: Also remove the `configure'

        by autoconf.  Add proper explicative comments.

        tests: avoid spurious failure of 'uninstall-fail.test' on Solaris
        * tests/uninstall-fail.test: All the Solaris 10 shells (/bin/sh,
        /bin/ksh, and /usr/xpg4/bin/sh), upon failing to chdir to a
        directory with the `cd' builtin, print a message like:
          "sh: /root: permission denied"
        which doesn't report the `cd' builtin anywhere.  Relax the grepping
        of the error message accordingly.

        tests: avoid spurious failure of 'uninstall-fail.test' on Cygwin
        * tests/uninstall-fail.test: Be sure to really skip this test

        directories.  Motivated by a spurious failure on Cygwin 1.5.

        tests: fix spurious failure with autoconf 2.62
        * tests/aclocal-path-precedence.test: Rewrite configure.in,
        rather than appending to it, to avoid spurious failures (at
        least with autoconf 2.62) due to repeated calls to AC_INIT.
        Also, add package name and version arguments to AC_INIT, to
        avoid spurious errors from automake.

        docs: avoid using colon character inside arguments of @pxref
        Fixes automake bug#9753
        * doc/automake.texi (VPATH Builds): Avoid using colon character
        `:' inside arguments of @pxref, as this can cause problems in
        the generated `.info' files, and such an usage will be explicitly
        forbidden by future texinfo documentation.

        parallel-tests: warn on conditional TEST_EXTENSIONS definition
        Before this change, automake would have still bailed out, but
        with a confusing error message (about an invalid redefinition
        of TEST_EXTENSIONS).
        * automake.in (handle_tests): Warn explicitly if TEST_EXTENSIONS
        has conditional contents.
        * tests/test-extensions-con.test: New test.
        * tests/Makefile.am (TESTS): Add it.

2011-10-06  Stefano Lattarini  <stefano.lattarini@gmail.com>

        parallel-tests: don't allow @substitutions@ in TEST_EXTENSIONS
        Even after the last commit `v1.11-476-g90bea64', the checks
        performed by automake on entries in $(TEST_EXTENSIONS) tried to
        allow for @substitited@ stuff.  This however ends up allowing
        quite brittle setups, which, most importantly, are of no real
        practical usefulness anyway.  So it's better to just disallow
        @substitutions@ in TEST_EXTENSIONS altogether, offering a clear
        error message, instead of risking weird bugs and unexpected
        behaviors in the generated Makefile.in.
        * automake.in ($TEST_EXTENSION_PATTERN): Turned from a regular
        expression ...
        (is_valid_test_extension): ... into this subroutine.  Don't allow
        generic @substitutions@ anymore (possibly making an exception for
        `@EXEEXT@' under the proper circumstances).
        * tests/test-extensions.test: Adjust and extend.

        tests: fix spurious failure in 'insthook.test'
        * tests/insthook.test (Makefile.am): Add a proper `uninstall-hook'
        target to remove the symlink created by the `install-exec-hook'
        target; this prevents "make distcheck" from failing spuriously.
        Since we are at it, delete an extra blank line, and add a trailing
        `:' command.

        parallel-tests: automake error our on invalid TEST_EXTENSIONS
        This change fixes automake bug#9400.
        * automake.in (handle_tests): Bail out if a suffix specified in
        TEST_EXTENSIONS would produce an invalid `xxx_LOG_COMPILER'
        variable or an invalid suffix rule.  Before this change, automake
        would have issued a confusing error messages (about invalid or
        non-POSIX variables being defined), and in some situations would
        have even produced a broken `Makefile.in' file.

        java: fix various blunders in test 'java-mix.test'
        * tests/java-mix.test: Add missing call to `set -e'.  Fix inverted
        semantics (`.java' files are expected *not* to be distributed by
        default, not the other way round).  Fix various typos in the name
        of the `.java' files.  Correct other minor blunders.  Improve some
        comments.

2011-04-23  Stefano Lattarini  <stefano.lattarini@gmail.com>

        java: allow both JAVA and nobase_JAVA in the same Makefile.am

        java: allow both dist_JAVA and nodist_JAVA in the same Makefile.am
        Fixes automake bug#8434.
        * automake.in (handle_java): Strip `dist_' and `nodist_' from
        the given prefix.  Define a new internal Makefile variable
        `am__java_sources'.  Related adjustments.
        * lib/am/java.am (JAVAC, JAVAROOT, CLASSPATH_ENV): Define only the
        first time this am file is processed.
        (class%DIR%.stamp): Stamp file renamed ...
        (class%NDIR%.stamp): ... to this, so that the `dist_' and `nodist_'
        prefixes are stripped from the name of the stampfile.  Adjust
        declaration of dependencies by using the new automake-generated
        internal variable `$(am__java_sources)'.  In the rule, use `$@'
        as the name of the target, rather than hard-coding it.
        * tests/java.test: Update and extend.

        tests: fix spurious failure on fast machines
        * tests/aclocal-acdir.test: Avoid spurious failures due to caching
        issues, by cleaning the autom4te cache between all the aclocal
        invocations, and by always calling autoconf with the `--force'
        flag.

2011-09-09  Stefano Lattarini  <stefano.lattarini@gmail.com>

        aclocal: better URL reference in error message
        * aclocal.in (scan_file): In the error message about underquoted
        definitions, reference the automake page at `www.gnu.org', not
        at `sources.redhat.com'.

2011-09-09  Stefano Lattarini  <stefano.lattarini@gmail.com>

2011-09-06  Stefano Lattarini  <stefano.lattarini@gmail.com>

        aclocal: more granularity in acdir overriding
        Before this change, using the `--acdir' option caused aclocal to
        redefine both the directory of automake-provided m4 macros and the
        directory of third-party system-wide m4 macros.  With this change,
        we deprecate the `--acdir' aclocal option, and introduce two new
        options `--automake-acdir' and `--system-acdir', to allow for more
        granularity.
        * aclocal.in (@automake_includes, @system_includes,
        @user_includes): Fix and extend comments.
        (usage): Update.
        (handle_acdir_option): New function.
        (parse_arguments): Recognize new options `--system-acdir' and
        `automake-acdir', and handle `--acdir' using the new function
        above.  Simplify logic by assuming that the directory of
        third-party system-wide m4 files always exists.
        * tests/aclocal.in: Update to use the new options, instead of
        the deprecated. `--acdir'.
        * m4/dirlist: Move ...
        * m4/acdir/dirlist: ... here.
        * m4/Makefile.am (EXTRA_DIST): Update.
        (m4datadir): Rename ...
        (automake_acdir): ... to this.  Accordingly, ...
        (dist_m4data_DATA): ... rename this ...
        (dist_automake_ac_DATA): ... to this.
        (system_acdir): New, directory.
        (dist_system_ac_DATA): New, defined to an empty value; this will
        ensure that the $(system_acdir) directory will be created by
        "make install".
        * tests/aclocal.test: Remove check about the `--print-ac-dir'
        option of aclocal, it has been moved into ...
        * tests/aclocal-print-acdir.test: ... this new test, and quite
        extended.
        * tests/aclocal-acdir.test: New test.
        * tests/Makefile.am (TESTS): Add the new tests.
        * NEWS, bootstrap: Update.
        * doc/automake.texi (aclocal Options, Macro Search Path): Update.

2011-09-05  Peter Rosin  <peda@lysator.liu.se>

        * tests/amhello-binpkg.test: Add missing $EXEEXT usage.

        * tests/Makefile.am (XFAIL_TESTS): Update.

2011-09-02  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tests: simplify wrapper for aclocal
        * tests/aclocal.in: Remove use of $ACLOCAL_TESTSUITE_FLAGS and
        extra `-I' flags; they are not really required, since the file
        `m4/amversion.m4' is generated in the srcdir anyway.
        * tests/acloca10.test: Remove use of $ACLOCAL_TESTSUITE_FLAGS.
        * tests/acloca18.test: Likewise.
        * tests/defs.in: Don't nullify $ACLOCAL_TESTSUITE_FLAGS, and do
        not export it.

2011-09-02  Stefano Lattarini  <stefano.lattarini@gmail.com>

        coverage: vala support failing for VPATH from-scratch builds

        * THANKS: Update.
        From a report by Zbigniew Jędrzejewski-Szmek.
        Related to automake bug#8753.

2011-09-01  Stefano Lattarini  <stefano.lattarini@gmail.com>

        docs: report few more automake parsing limitations
        Partly motivated by automake bug#8360.
        * doc/automake.texi (General Operation): Report few more automake
        limitations w.r.t. parsing of unusual makefile constructs.  Related
        minor reorderings.
        * tests/doc-parsing-buglets-colneq-subst.test: New test.
        * tests/doc-parsing-buglets-tabs.test: Likewise.
        * tests/Makefile.am (TESTS): Update.

2011-08-25  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tests: list "forgotten" test script in TESTS
        * tests/Makefile.am (TESTS): Also list ...
        * tests/java-empty-classpath.test: ... this test.  Since we are
        at it, remove trailing whitespace from a couple of lines.

2011-08-25  Eric Blake  <eblake@redhat.com>

        ylwrap: fix unusual indentation whitespace
        * lib/ylwrap: Convert tabs to spaces.

        java: avoid compilation errors when CLASSPATH is empty
        * lib/am/java.am (CLASSPATH_ENV): When redefining `$CLASSPATH',
        do not append an empty component in case the previous value of
        CLASSPATH is empty or unset.
        * tests/java-empty-classpath.test: New test.
        * tests/Makefile.am (TESTS): Update.
        Fixes automake bug#9306.

2011-08-16  Stefano Lattarini  <stefano.lattarini@gmail.com>

        parallel-tests: no more spurious successes for FreeBSD make
        Work around a bug of FreeBSD make bug that was causing the
        automake-generated "check" target to complete with success
        even if some tests failed; this happened only when FreeBSD
        make was run in concurrent mode (as in, e.g., "make -j2
        check").  The bug is not present in NetBSD make.
        This change fixes automake bug#9245:
         <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9245>
        See also FreeBSD PR bin/159730:
         <http://www.freebsd.org/cgi/query-pr.cgi?pr=159730>
        * lib/am/check.am [%?PARALLEL_TESTS%] $(TEST_SUITE_LOG): Use a
        more "safe" (and apparently redundant) idiom to exit with error,
        so that the non-zero exit status is picked up also by FreeBSD
        make when it's running in concurrent mode.
        * NEWS: Update.
        * tests/check-concurrency-bug9245.test: New test.
        * tests/Makefile.am (TESTS): Update.

        hacking: we now require autoconf 2.68
        * HACKING ("Working in git"): Use autoconf and autom4te 2.68,
        not 2.67, in the examples.

2011-08-08  Stefano Lattarini  <stefano.lattarini@gmail.com>

        test defs: more environment cleanup
        * tests/defs.in: Also unset variables AM_COLOR_TESTS and
        AM_TESTS_ENVIRONMENT.

2011-08-08  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tests: fix spurious failure with Solaris make
        * tests/distcheck-configure-flags-am.test: Avoid using `+=' too
        liberally with AM_DISTCHECK_CONFIGURE_FLAGS, since the line breaks
        so introduced, in conjunction with single quotes, might confuse
        Solaris make.

2011-08-03  Stefano Lattarini  <stefano.lattarini@gmail.com>

        maintcheck: fix maintainer-check failures, both real and spurious
        * tests/amhello-binpkg.test: Use "$MAKE", not bare "make".
        * Makefile.am (sc_perl_local): Also allow perl special variable
        `$~' to be localized.  And be slightly laxer in the regexp, to
        allow for usages like "local $_ = $foo;".
        (sc_tests_overriding_macros_on_cmdline): Also allow for command
        line overriding of the `DISABLE_HARD_ERRORS' make variable.  Try
        to avoid false positives for usages like "$MAKE || st=$?".

2011-07-23  Stefano Lattarini  <stefano.lattarini@gmail.com>

        tests: relax a test on amhello examples to cater to Solaris tar
        * tests/amhello-binpkg.test: When the tar implementation in use
        is not GNU tar, relax the tests on tar output, to avoid spurious
        failures.  For example, "tar cvf ..." with GNU tar can output
        lines like "./usr/bin/hello" on the standard output, while with
        Solaris tar it can output lines like "a ./usr/bin/hello 8K" on
        standard output, and with Heirloom tar it can output lines like
        "a ./usr/bin/hello 15 tape blocks" on standard error.

        tests: fix weakness in 'tests-environment-backcompat.test'
        * tests/tests-environment-backcompat.test: Do not override the
        content of xfailing test `baz.test' with a "weaker" version that
        fails unconditionally: the test must fail only when the 'strict'
        pragma is in use, in order not to reduce coverage.

        tests: portability fixes in tests on amhello examples
        * tests/amhello-binpkg.test: Don't use "tar xzf too.tag.gz" to
        extract a gzip-compressed tarball, that's unportable to some
        tar implementations; use the "gzip -dc fo.tar.gz | tar xf -"
        idiom instead.

        check: don't use multi-line coloring for the report
        "less -R" can't handle multi-line coloring as it is done for the
        check reports of the serial and parallel testsuite, because of
        performance reasons.  Thus, color each line of the check report
        by its own.

        docs: AM_DISTCHECK_CONFIGURE_FLAGS is for corner cases
        * doc/automake.texi (Checking the Distribution): Explain that the

        requiring any special configure options, so that in general
        AM_DISTCHECK_CONFIGURE_FLAGS shouldn't be used.  Give an example
        of where its use is legitimate.
        Suggestions from Ralf Wildenhues and Eric Blake.

        test defs: new function 'fatal_', for hard errors
        Before this patch, the only way offered by tests/defs to
        properly signal a hard error was the `framework_failure_'
        function.  But the error message issued by that function,
        as its name would suggest, refers to a set-up failure in the
        testsuite, while hard errors can obviously also be due to
        other reasons.  The best way to fix this inconsistency is to
        introduce a new function with a more general error message.
        Inspired by a recent similar change to Gnulib's tests/init.sh.
        * tests/defs.in (fatal_): New function.
        * tests/README (Section "Writing test cases" subsection "Do"):
        Suggest the use of `fatal_', not of `framework_failure_', for
        generic hard errors.  The latter should be reserved for "real"
        set-up failures.

        remake: behave better with non-GNU make in subdirectories
        Currently, with every decent make program, it is possible to
        rebuild out-of-date autotools-generated files with a simple
        "make Makefile" -- but for this to work reliably with non-GNU
        make implementations, the command must be issued from the

        automake, aclocal: honour configure-time AUTOCONF and AUTOM4TE
        Currently, the Automake's own configure script allow definition
        of AUTOCONF and AUTOM4TE, expected to point respectively to an
        autoconf and autom4te programs.  But while these definitions are
        honoured in the Automake's build systems and test suite, they
        were *not* honoured in the generated `automake' and `aclocal'
        scripts.  This behaviour, apart from being wrong in that it does
        not allow the user enough freedom in choosing his tools, also
        caused inconsistencies in the test suite, brining to spurious
        failures.
        Problem reported by Graham Reitz on the automake list; see thread:
        <http://lists.gnu.org/archive/html/automake/2011-05/msg00022.html>
        * automake.in ($traces): Use `@am_AUTOCONF', not simply `autoconf'.
        * aclocal.in ($traces): Use `@am_AUTOM4TE', not simply `autom4te'.
        * Makefile.am (do_subst): Substitute also `@am_AUTOCONF' and

        build: the user can override AUTOM4TE, AUTORECONF and AUTOUPDATE too
        Our build system allows the user to override AUTOCONF and AUTOHEADER
        at configure time, and honours these overrides in our testsuite.
        But it didn't do the same with AUTOM4TE, AUTORECONF and AUTOUPDATE.
        This change fixes that inconsistency.
        * configure.ac (am_AUTOM4TE, am_AUTOUPDATE, am_AUTORECONF): New
        AC_SUBSTitutions.  Update comments.

        tests/README: fix example about `make -e' usage
        * tests/README (Section "Writing test cases" subsection "Do"): When
        some variable is never initialized in the Makefile, `-e' is not
        necessary in order to override it.  DESTDIR is such a variable: we
        ensure that we do not ever initialize it.  And as such, it is quite
        portable to use:
          $ make DESTDIR=/foo/bar install
        and in fact, quite widely used.
        So our example about when `make -e' is required, which references
        the `DESTDIR' variable, is poorly chosen, if not downright wrong.
        Rewrite it to use `prefix' as the overridden variable instead.

        testsuite: avoid re-running few tests with 'parallel-tests' option
        Some tests in our testsuite use the 'simple-tests' driver only
        marginally, or simply as a mean to conveniently check unrelated
        invariants.  It makes little sense to force these tests to also
        run with the 'parallel-tests' Automake option active, as doing so
        offers no real gain in coverage, while often causing a measurable
        overhead in execution time (for an already too-slow testsuite).
        * tests/pr401.test (parallel_tests): Define to "no", to prevent
        the generation of a sibling test script using the 'parallel-tests'
        driver.

        tests/README: update obsoleted advice
        * tests/README (Section "Writing test cases" subsection "Do"):
        Do not suggest to use the `*-p.test' pattern for the names of
        hand-written tests which use the `parallel-tests' Automake option.
        Not only is this not respected by the existing tests, but it is
        more likely to cause conflicts with auto-generated tests.
        So, suggest to *avoid* using the `*-p.test' pattern in names
        of hand-written tests instead.
        (Section "Writing test cases" subsection "Do not"):  When
        suggesting not to override Makefile variables using command
        line arguments, do not use the badly outdated variables `U'
        and 'ANSI2KNR' in the example; instead, use the more common
        and typical `DESTDIR'.

        This is required because at least FreeBSD `ls' do not sort files
        with the same timestamp in alphabetical order when using the `-t'

        tests defs: allow requirements for compilers (mostly dummy)
        Most of the new requirements that are now accepted in `$required'
        as consequence of this patch are still dummy.  They are planned
        to be implemented only in master (or in some derived branch), but
        having them here (even just as no-op) will allow for an easier
        integration/backporting of potential new testcases.
        * tests/defs.in (cc, c++, fortran, fortran77): New requirements,
        still dummy.

        implementation, looking for a generic `lex' program, will follow
        in the future.

        test defs: fix 'javac' requirement for older JDK versions
        The Java compiler from JDK 1.5 (and presumably earlier versions)
        cannot handle the `-version' option by itself; and while it does
        print the version number, it then errors out with an usage error:
          $ javac -version
          javac 1.5.0_22
          javac: no source files
          Usage: javac <options> <source files>

        maintcheck: look for problematic names of testcases
        The configure.in stub created by default by `tests/defs' obtains
        the first argument of AC_INIT from the test name, and this can
        cause some supported autoconf versions to fail with a spurious
        error if that test name contains the name of an m4 or m4sugar
        builtin or macro (e.g., `defn' or `m4_undefine').
        See for example the bug fixed by commit v1.11-287-g1325a8a.
        This change add a maintainer check that warns about test names
        which are possibly problematic in this regard.
        * Makefile.am (sc_test_names): New maintainer-check target.
        (syntax_check_rules): Add it.

        libtool: suggest LT_INIT if LTLIBRARIES primary is used
        When the LTLIBRARIES primary was used, but $(LIBTOOL) wasn't
        defined, automake suggested to add a call to AC_PROG_LIBTOOL
        in configure.ac.  But that macro is deprecated since Libtool
        version 1.9b (2004-08-29), in favor of the newer LT_INIT.  So
        suggest the use of this latter macro instead.
        * lib/Automake/Variable.pm (%_am_macro_for_var): Pair 'LIBTOOL'
        with 'LT_INIT', not with 'AC_PROG_LIBTOOL'.
        * tests/libtool4.test: Adjust and extend.  Also, add a call to
        macro AC_PROG_CC in configure.in, to help ensuring that automake

        * tests/ltinit.test: New test, ensure that automake's libtool
        support works with LT_INIT-based interface.

        Improve, extend and tweak tests on Texinfo support.
        * tests/instdir-texi.test: Add a call to `ls -l' after that to
        `make', for debugging.  When looking for required tools, do not
        redirect the output of "$tool --help" to /dev/null, and do not
        uselessly run it in a subshell.
        * tests/txinfo.test: Rewritten to run autoconf, ./configure and
        make.  All checks moved into Makefile.am.

        Makefile.in stricter.
        * tests/txinfo7.test: Enable `errexit' shell flag, and related
        changes.  Add trailing `:' command.  Do not add unnecessary stuff
        to Makefile.am.
        * tests/txinfo9.test: Verify that more targets which are expected
        to be generated only once really are.  Make grepping less strict,
        to avoid exposing too much internal details.  More minor changes.
        * tests/txinfo16.test: Add trailing `:'.  Prefer cat over echo
        for appending to configure.in.  Updated/fixed heading comments.
        * tests/txinfo23.test: Likewise, and extended a little by making

        cleaned also by "make clean", not only by "make distclean".
        * tests/txinfo22.test: Prefer `$me' over hard-coded test name,
        and added trailing `:' command.  This testcase also used to check
        that automake ignores in-line comments when using variables, but
        preserves them in the output; these checks (added in commit
        "Release-1-7f-4-g9177ef8") do not really pertain to this test,
        so they have been moved ...
        * tests/comments-in-var-defn.test: ... into this new test.
        * tests/txinfo4.test: Escape literal dots in grep regexps.  Add
        trailing `:' command.
        * tests/txinfo29.test: Likewise.  Relax grepping of generated
        Makefile.in w.r.t. whitespaces.  Prefer `cat' over `echo' to
        append to configure.in.
        * tests/txinfo3.test: Likewise.
        * tests/vtexi.test: Improve grepping of Makefile.in (sometimes
        make it stricter, sometimes laxer).  Move `set -e' setting just
        after the inclusion of ./defs.  De-uglify a sed command.  Other
        minor cosmetic improvements.
        * tests/vtexi2.test: Make grepping of Makefile.in stricter.  Add
        trailing `:' command.

        Fix spurious failures in `silent*.test' for $CC != gcc
        In some tests on automake-produced silent rules, we forced the
        use of gcc depmode to improve testsuite coverage; but this has
        unsurprisingly led to spurious failures when some non-GNU C
        compilers were used.  So we are now careful to require GCC in

        * config-ml.in: Add Go support: treat GOC and GOCFLAGS like other
        compiler/flag environment variables.

2010-11-19  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Automake::Config: remove extra trailing semicolon.
        * lib/Automake/Config.in: Remove extra trailing semicolon.

        help4.test: fix botched heading comment.
        * tests/help4.test: Fixed the heading comment, since it
        didn't correctly describe what checks the testcase was
        supposed to perform.

        help2.test: add checks on aclocal too.
        * tests/help2.test: Check that also `aclocal --version' and
        `aclocal --help' work with configure.in and acinclude.m4 both
        broken.

2010-11-17  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Fix spurious failures of silent-rules tests with Sun Fortran.
        * tests/silentf77.test: Strip from the make output some verbose
        messages possibly printed by the SunStudio fortran compilers, to
        avoid spurious failures.  Add a trailing `:' command.
        * tests/silentf90.test: Likewise.

2010-11-17  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Fix spurious failures of silent5.test with Sun Fortran.
        * tests/silent5.test: Strip from the make output some verbose
        messages possibly printed by the SunStudio fortran compilers,
        to avoid spurious failures.  This bug has been there from the
        very first version of this test script.

2010-11-16  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Fix regression in colon{5,6}.test (failures on AIX 5.3).
        * tests/colon5.test: Also substitute `@SHELL@' with `$SHELL' when
        post-processing the generated Makefile.in, to work around a bug
        of AIX 5.3 make which doesn't allow setting the `$(SHELL)' macro
        on the commend line.  Calls to `$MAKE' adjusted accordingly.
        * tests/colon6.test: Likewise.
        Regression introduced in commit v1.11-175-gf9fe878 "Modernize,
        improve and/or extend tests `colon*.test", and reported by Ralf
        Wildenhues.

2010-11-16  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Fix regression in ansi.test (failure on AIX 5.3).
        * tests/ansi.test: Remove redundant hackish check done using a
        hand-postprocessed Makefile.in.  This check worked by setting
        the `$(SHELL)' macro on the command line of make, but this is
        not supported by the AIX 5.3 make implementation.
        This bug has been lurking for a long time, and was activated by
        commit v1.11-125-gc1f6cdb "Enable `errexit' shell flag in various
        tests".  Report by Ralf Wildenhues.

2010-11-16  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        tests: avoid '##'-style comments inside recipe commands.
        * tests/confh.test, tests/confh8.test: Remove
        double-hash comments from makefile rule commands, they
        are not part of the Automake API.

2010-11-14  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        tests: work around dash quoting issue in case statements.
        * tests/color.test, tests/color2.test: Quote variable in case
        pattern, to avoid skipping tests with dash 0.5.5.1.

2010-11-14  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Rebuild menus in the manual.
        * doc/automake.texi: Rebuild menus (using ^C ^U ^A in emacs).
        Thanks to Ian Lance Taylor for the suggestion.

        Fix install-strip when $(STRIP) contains several words.
        * lib/am/install.am (install-strip): Update comment.  Use
        separate sub-make invocations for empty and nonempty $(STRIP),
        to fix quoting issues.
        * tests/strip2.test, tests/strip3.test: New tests.
        * tests/Makefile.am (TESTS): Adjust.

2010-11-10  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        * tests/yaccdry.test: Require bison.
        Found by NixOS Hydra.

2010-11-07  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Fix a bug in variable concatenation with `+='.
        * lib/Automake/VarDef.pm (append): Since the content of the
        "appended-to" variable is going to be unconditionally normalized
        later, simply separate the appended value with a single whitespace
        character, instead of trying to be uselessly smarter by using
        escaped newlines.  This fixes a bug in which extra backslashes
        where erroneously inserted in the variable's final value.
        * tests/pluseq11.test: New test, exposing the bug.
        * tests/Makefile.am (TESTS): Update.
        Reported by Andy Wingo.

2010-11-06  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Fix bug in rules for creating vala vapi/header files.
        * automake.in (lang_vala_finish_target): Add forgotten "fi" in an
        if control structure in a generated make rules.  Bug introduced
        by previous commit `v1.11-221-gd7c1679', and revealed by failure
        of test `vala2.test'.

2010-11-01  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Fix and document rules to not touch the tree with `make -n'.
        * doc/automake.texi (Multiple Outputs): Document the problem of
        modifications during dry-run execution, propose solution.
        * NEWS: Update.
        * automake.in (lang_vala_finish_target): Split recipe so the
        stamp file is not removed with GNU `make -n'.
        (lang_yacc_target_hook): Separate removal of parser output file
        and header remaking.
        * lib/am/lisp.am ($(am__ELCFILES)): Determine whether -n was
        passed to make, take care not to remove any files in that case.
        * lib/am/remake-hdr.am (%CONFIG_H%): Separate removal of
        %STAMP% file from induced remaking of config header.
        * tests/autohdrdry.test, tests/lispdry.test, tests/yaccdry.test:
        New tests.
        * tests/Makefile.am (TESTS): Update.

2010-11-01  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Add FAQ entry for bug reporting instructions.
        * doc/automake.texi (Reporting Bugs): New section.

        Add support for newer python versions.
        * m4/python.m4 (AM_PATH_PYTHON): Add python2.7 and python3.2 to
        _AM_PYTHON_INTERPRETER_LIST.  Since we are at it, break a long
        line and fix indentation.
        * THANKS: Updated.
        From a report by Thomas Klausner.

        Add test for `AM_WITH_DMALLOC' macro.
        * tests/dmalloc.test: New test.
        * tests/Makefile.am (TESTS): Update.

        Fix nits and bugs in tests `help*.test'.
        * tests/help4.test: Fix broken sed commands used to strip `-W...'
        flags away from "$AUTOMAKE" and "$ACLOCAL".
        * tests/help3.test: Likewise, and fix a botched comment.
        * tests/help.test: Likewise.  Also, use "AUTOMAKE_fails ..."
        instead of "$AUTOMAKE ... && Exit 1", for consistency and to
        please maintainer-check.
        * tests/help2.test: Likewise.

2010-10-03  Stefano Lattarini  <stefano.lattarini@gmail.com>
            Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Improve tests `help*.test' (also fixes maintcheck failures).
        * tests/help.test: To run automake, use `$AUTOMAKE' with all `-W'
        flags stripped away rather than hard-coded `automake-$APIVERSION',
        to better honour user-overrides.  Similarly for aclocal.
        * tests/help2.test: Likewise.
        * tests/help3.test: Likewise.
        * tests/help4.test: Likewise.

2010-10-03  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Document and fix expansion of variables before rules.
        * doc/automake.texi (General Operation): Document that variables
        are expanded before rules.
        * lib/am/check.am (am__check_post): Reword a bit so it does not
        get matched as a rule.
        Suggestion by Ben Pfaff.

2010-10-02  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Revert "parallel-tests: avoid command-line length limit issue."
        This reverts commit 24e3b4ee2f8cb9f72dd94a05a893f3d4e88b7835,
        because it re-opened the bug fixed by v1.11-10-g218e678.

        2010-09-07  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        parallel-tests: avoid command-line length limit issue.

        substitution %MAKEFILE%.
        (generate_makefile): Adjust.
        * lib/am/check.am [%?PARALLEL_TESTS%] (check-TESTS): Pass
        sanitized TEST_LOGS value as makefile snippet on standard
        input to $(MAKE), to avoid exceeding the command line limit on
        w32 (MSYS).
        * NEWS: Update.
        Report by Bob Friesenhahn.

2010-09-26  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Extend tests on `--help' and `--version' options.
        * tests/help.test: Create a new empty directory and chdir into
        it, rather than removing already present files.  Run the aclocal
        and automake wrapper scripts directly, instead of relying on
        $AUTOMAKE and $ACLOCAL.  Be sure to correctly match literal dots
        in aclocal's and automake's stderr.  Add a trailing `:' command.
        * tests/help2.test: New test, checking that options `--help' and
        `--version' works in directories with broken `configure.in'.
        * tests/help3.test: New test, checking that options `--help' and
        `--version' take precedence on the other options.
        * tests/help4.test: New test, checking that the first among the
        `--help' and `--version' options to be specified on the command
        line wins.

        Testsuite: Use `$PATH_SEPARATOR', not `:', when extending PATH.
        * tests/compile2.test: Do no uselessly (implicitly) repeat the
        computation of PATH_SEPARATOR again.
        * tests/instmany-mans.test: Use `$PATH_SEPARATOR', not `:', when
        extending/redefining PATH.

        Updated.
        * Makefile.am (sc_tests_PATH_SEPARATOR): New maintainer check.
        (syntax_check_rules): Updated.

        Testsuite: new variables `$PATH_SEPARATOR' and `$APIVERSION'.

        ($ACLOCAL, $AUTOMAKE): Use it.
        ($PATH_SEPARATOR):  New AC_SUBST'd variables.
        ($PATH): Use it.

2010-09-22  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Manual: be more agnostic w.r.t. version control system used.
        * doc/automake.texi (Basics of Distribution): Also refer to `.svn'
        directories as a type of probably-unwanted files that are copied
        regardless when adding directories to EXTRA_DIST.
        (The dist Hook): Show a dist-hook example which removes Subversion
        `.svn' private directories from distdir, rather than CVS private
        directories.
        (missing and AM_MAINTAINER_MODE): Try to be more agnostic w.r.t.
        the version control system used.

        Manual: index refer to target "git-dist", not "cvs-dist".
        * doc/automake.texi (General Operation): Index the non-standard
        example about "git-dist" under the "git-dist" label, not under
        the "cvs-dist" one.

        Perl modules: remove references to "Automake CVS repository".
        * lib/Automake/Channels.pm: Update comments to refer to "Automke's

        lib/Automake/.cvsignore, lib/Automake/tests/.cvsignore,
        m4/.cvsignore, tests/.cvsignore: Files deleted.  Even when using
        savannah's CVS readonly mirror there's no way to commit back to
        the real repository, so this files are not worth maintaining or
        keeping around.

2010-09-21  Stefano Lattarini  <stefano.lattarini@gmail.com>

        * m4/dmalloc.m4: Bump serial number and copyright years.

2010-09-20  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Fix broken link in `AM_WITH_DMALLOC' help screen.
        * m4/dmalloc.m4 (AM_WITH_DMALLOC): Refer only to the dmalloc site
        `http://www.dmalloc.com', not to the dmalloc tarball there (which
        seems to have been removed, substituted by multiple release
        tarballs now).

2010-09-12  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Fix regression in test `colon4.test'.
        * tests/colon4.test: Fix botched editing to `configure.in'
        that made the test useless.  Since we are at it, improve
        comments and make grepping of generated Makefile.in slightly
        stricter.
        Regression introduced by change "Modernize, improve and/or
        extend tests `colon*.test" (Stefano Lattarini, 2010-08-08).

2010-09-08  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Do not require "gzip" explicitly in tests.
        The gzip utility is simply expected to be present on any decent
        target system for Automake.  So it's pointless to put it in
        $required.
        * tests/install2.test ($required): Do not require "gzip".
        * tests/lex3.test: Likewise.
        * tests/pr9.test: Likewise.
        From a suggestion by Ralf Wildenhues.

        Make some `confh*.test' tests more "semantic" (plus tweakings).
        * tests/confh.test: Run "autoconf", "configure" and "make check",
        instead of munging/grepping the generated `Makefile.in'.
        * tests/confh4.test: Relax the grepping of Makefile.in w.r.t.
        white spaces.  Do not create useless dummy source file `foo.c'
        and useless dummy header file `acconfig.h'.
        (configure.in): Remove superfluous call to `AC_OUTPUT'.
        * tests/confh6.test: Add trailing `:' command.
        * tests/confh7.test: In comments, add reference to ...
        * tests/confh8.test: ... this new test, "semantic" sister
        of `confh7.test'.
        * tests/Makefile.am (TESTS): Updated.
        Prompted by a report from Ralf Wildenhues.

        Remove useless whitespace padding in XFAIL_TESTS definition.
        * tests/Makefile.am (XFAIL_TESTS): Remove whitespace padding.

2010-08-27  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Fix bug in test missing6.test.
        * tests/missing6.test: Fix the hack used to edit `configure.in',
        to avoid producing a configure script that breaks with shells
        that do not support $LINENO.  Also throw in a couple of cosmetic
        changes.

2010-08-21  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Improve robustness of mdate-sh script.

            Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Docs: clarify how to avoid automatic dependencies tracking.
        * doc/automake.texi (Automatic dependency tracking): Mention that
        automatic dependencies tracking is enabled by default, but that
        the package developer can disable it altogether.  Add a reference
        to the proper section for a more in-depth explanation.

        Fix typo in manual (`Makefile.in' instead of `Makefile.am').
        * doc/automake.texi (Automatic dependency tracking): Fix typo.

2010-08-16  Bruno Haible  <bruno@clisp.org>

        Don't hide the table of contents.

        `cmp', and add some "cosmetic" blank lines.

2010-08-09  Stefano Lattarini  <stefano.lattarini@gmail.com>

        `CC=gcc' to configure explicitly (it's already exported globally
        in ./defs, since we have "gcc" in $required).  Use the stub for
        `configure.in' created by ./defs, rather than writing it from
        scratch.  Do not create dummy files required by "gnu" mode (e.g.
        README, NEWS), since we run automake in foreign mode anyway.

        Add some comments explaining why we don't use the `configure.in'
        stub preset be ./defs.
        * tests/confh.test: Use the `configure.in' stub created by ./defs,
        rather than writing one from scratch, and do not call AC_OUTPUT.
        Enable `errexit' shell flag, and related changes.  Prefer diff over
        cmp to compare text files. Prefer perl over sed to fetch the value

        and make grepping of `config.h' and `config.h.in' stricter.
        * tests/conf2.test: Renamed ...
        * tests/confh7.test: ... to this.  Use the `configure.in' stub
        created by ./defs, rather than writing one from scratch.  Try to
        run the checks both with and without AC_PROG_CC and AC_OUTPUT in
        `configure.in'.
        * tests/Makefile.am (TESTS): Updated.

        * tests/depcomp.test: Do not create useless dummy source files.
        Add a trailing `:' command.
        * tests/depcomp2.test: Use `unset' on the CFLAG variable to ensure
        it's not in in the environment, rather than exporting it with an
        empty value.  Do not pass CC=gcc to configure, as that's already
        done in ./defs since we have gcc in $required.  Ensure verbose
        printing of captured stderr, and normalize its checking.  Add a
        trailing `:' command.
        * tests/depcomp3.test: Quote literal dots and dollar characters in
        grep regexps.  Always use `: >' rather than `touch' to create empty

        configure.in.  Cosmetic fixes to spacing.  Make the "dummy" `if'
        statement required by OpenBSD's sh `set -e' more robust, and add
        explanatory comments to it.

        Separate failing part of test `all.test'.
        * tests/all.test: Keep only (x)failing part of the test.  Working
        checks moved out to ...
        * tests/all2.test: ... this new test.

        `Makefile.in' stricter.
        * tests/subobj5.test: Add trailing `:' command.  Move setting of
        `errexit' shell flag earlier in the script (just after inclusion
        of ./defs).
        (configure.in): Use the stub created by `./defs', rather than
        writing it from scratch, and avoid obsolescent constructs.
        * tests/subobj6.test: Add trailing `:' command.  Move setting of
        `errexit' shell flag earlier in the script (just after inclusion
        of ./defs).  Do not create useless dummy ac-init file `f'.
        * tests/subobj7.test: Do not create useless dummy ac-init file
        `f'.
        (configure.in): Use the stub created by `./defs', rather than
        writing it from scratch, and avoid obsolescent constructs.
        * tests/subobj9.test: Move setting of `errexit' shell flag earlier
        in the script (just after inclusion of ./defs).  Fail the test if
        `make distcheck' fails.  Ensure verbose printing of captured make
        stdout.  Avoid useless fork by doing simple grep instead of using
        test -n "`COMMAND | grep ...`".
        (configure.in): Normalize the call to AC_INIT w.r.t. other tests.
        (Makefile.am): Explicitly mark target "print" as phony.
        * tests/subobj10.test: Removed duplicated call to `set -e'.  Add
        trailing `:' command.
        (configure.in): Normalize the call to AC_INIT w.r.t. other tests.

        Remove a couple of obsoleted tests.

        autoconf and autom4te programs used by the bootstrap process.

        Bootstrap: fixlet.
        * bootstrap: Do not remove `lib/Automake/Config.pm' anymore,
        since we don't generate it.  Correctly quote arguments of
        `eval' builtin.  Fixed a botched error message.  Removed an
        extra blank line.

        Bootstrap: don't search perl in $PATH.
        * bootstrap: Do not explicitly search perl in $PATH anymore.
        ($PATH_SEPARATOR): Removed, it's no more needed.

        Bootstrap: let the user choose which autoconf to use.
        * bootstrap ($AUTOCONF): New variable, from the environment.
        ($AUTOM4TE): Likewise, for clarity.

        time stamp differences.

        Sync auxiliary files from upstream.
        * lib/config.guess, lib/config.sub, lib/texinfo.tex:
        Sync from upstream.

        Work around a nasty bug (segfault) of Solaris make.
        * lib/am/check.am (recheck, recheck-html): Trim trailing spaces
        from $list, to avoid triggering a nasty bug (potential segfault)
        on Solaris make.

2010-08-06  Peter Rosin  <peda@lysator.liu.se>

        Make cond5.test more robust on MSYS.
        * tests/cond5.test: Add delay before the first kill attempt to
        cater for problems with MSYS bash.

2010-07-31  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Add example git work flow; discuss merge --log in HACKING.
        * HACKING: Update.
        Suggestion by Stefano Lattarini.

        Add more hints for debugging make rules.
        * doc/automake.texi (Debugging Make Rules): Show command to find

        variable, rather than re-evaluating the shell expression for
        the condition.
        * tests/cond40.test: Extend test.
        * NEWS: Update.

        Avoid syntax error if IF-TRUE part of AM_COND_IF expands empty.
        * m4/cond-if.m4 (AM_COND_IF): Ensure IF-TRUE part is never empty
        to avoid shell syntax error if the m4 expansion is empty.
        * tests/cond40.test: Enhance test.

2010-07-21  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Modernize and improve test scripts `subdir*.test'.
        * tests/subdir.test: Enable `errexit' shell flag, and related
        changes.  Use the `configure.in' stub created by `./defs',
        rather than writing one from scratch.
        * tests/subdir2.test: Likewise.
        * tests/subdir4.test: Likewise.
        * tests/subdir3.test: Enable `errexit' shell flag, and related
        changes.  Do not create useless dummy source files.
        * tests/subdir5.test: Make grepping of Makefile.in (in topdir
        and in subdirs) stricter.  Some minor changes to keep it more
        in sync with the related test `subdir8.test'.
        * tests/subdir8.test: Likewise (but with the related test being
        `subdir5.test' here).
        * tests/subdir6.test: Cosmetic change in spacing.
        * tests/subdir9.test: Define and use new variable `$distdir'.  Add
        trailing `:' command.
        * tests/subdir10.test: Cosmetic consistency-related change.
        * tests/subdirbuiltsources.test: Cosmetic changes in spacings.
        (configure.in): Use stub created by `./defs', rather than writing
        it from scratch.  Do not use obsoleted and/or deprecated forms of
        autoconf/automake macros.

        Modernize and improve test scripts `dist*.test'.
        * tests/distcleancheck.test: Do not add useless `-e' option to
        a $MAKE call.  Extend test by grepping stderr of make.
        * tests/distcom2.test: Do not run the same test script on the
        Makefile.in twice, but save its output in an intermediate file
        instead.  Make grepping of DIST_COMMON definition stricter.
        Display the content of more files, to ease debugging.  Add a
        trailing `:' command.  Improved heading comments w.r.t. sister
        test(s).
        * tests/distcom6.test: Likewise, and avoid to uselessly run
        autoconf.
        * tests/distcom3.test: Ensure verbose printing of captured stdout
        and stderr.  Make grepping of captured stderr stricter.  Also,
        add trailing `:' command.
        * tests/distcom4.test: Declare the target `test' in the generated
        Makefile.am as `.PHONY'.  Display content of more files, to ease
        debugging.  Add trailing `:' command.
        * tests/distcom5.test: Likewise.  Also, factor out common sed
        script in subroutine `extract_distcommon'.
        * tests/distcom7.test: Prefer cat + here-doc over echo to write
        test Makefile.am files.  Add a trailing `:' command.
        * tests/distname.test: Prefer `gzip -d' over `gunzip'.  Move the
        call to `set -e' earlier.  Be stricter and more verbose in the
        checking of the generated tarball.
        (configure.in): Use the stub provided by ./defs, instead of
        writing it from scratch.  Avoid obsoleted constructs.  Remove
        useless call to `AM_PROG_CC_C_O'.
        * tests/distdir.test: Various minor improvements/normalizations.
        * tests/distlinks.test: Likewise.

2010-07-18  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Improve and extend test cond5.test.
        * tests/cond5.test: Do not blindly sleep 60 seconds before polling
        the background automake process, but poll it every 10 seconds for
        at most 30 times (this makes the test both faster on good machines,
        and more resilient to spurious timeout-due failures when in low
        priority or on heavily-loaded systems).
        Check also that automake writes the expected error messages on the
        standard error.
        Enable `errexit' flag, and related changes.
        Rely on the `configure.in' stub created by `./defs', rather than
        writing one from scratch.

2010-06-26  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Update program --help output to match current GCS.

        Fix typo-related bug in test script silent5.test.
        * tests/silent5.test: Use $EGREP, not $GREP (which is not even
        defined).

        Tests: remove useless repetitions of `foreign' automake option.
        * tests/multlib.test (configure.in): Remove useless use of
        `foreign' option in AM_INIT_AUTOMAKE (the `--foreign' option is
        already in $AUTOMAKE by default, so no point in repeating it).
        * tests/subobj10.test: Likewise.
        * tests/subobj9.test: Likewise.

        Fix bugs in test script silent5.test.
        * tests/silent5.test: Fixed a nasty bug (due to the use of grep
        instead of egrep) that could have led to false negatives.

2010-06-21  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Add a test checking that distributed broken symlinks cause

        declaration, to please compilers.

2010-06-21  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Fix bugs in Automake Yacc/Lex support w.r.t. $(AM_FLAGS) and
        $(FLAGS) precedence.
        * automake.in: Fix registration of languages "Lex", "Lex (C++)",
        "Yacc" and "Yacc (C++)", so that $(LFLAGS) has precedence over
        $(AM_LFLAGS) and $(YFLAGS) has precedence over $(AM_YFLAGS).
        * tests/Makefile.am (XFAIL_TESTS): Updated accordingly.
        * NEWS: Updated.

        New tests, exposing bugs in Automake Yacc/Lex support w.r.t.
        $(AM_FLAGS) and $(FLAGS) precedence.

        changes.  Make grepping of Makefile.in slightly stricter.
        * tests/suffix.test: Enable `errexit' shell flag, and related
        changes.  Also, do not redirect grep output to /dev/null, as this
        might unmotivatedly hide useful information.
        * tests/suffix2.test: Move setting of `errexit' shell flag earlier
        in the script (just after inclusion of ./defs).  Use a more
        idiomatic way to count text occurrences in Makefile.in with
        grep.  Do not create useless dummy source files.
        * tests/suffix10.test: Ensure verbose printing of captured make
        stdout.  Minor cosmetic changes.
        * tests/suffix8.test: Likewise.  Also, drop useless call to the
        env(1) utility, and make grepping of make output stricter by using
        $FGREP rather than plain grep.
        * tests/suffix11.test: Likewise.
        * tests/suffix12.test: Likewise.
        * tests/suffix9.test: Prefer cat + here-doc over echo to append to

        useless `if' statement is indeed required.

        Add useful comment in test script obsolete.test.
        * tests/obsolete.test: Add a comment explaining why we need
        an indirection in adding $AUTOUPDATE to $required.

        Normalize whitespaces in 'tests/Makefile.am'.
        * tests/Makefile.am (TESTS): Use only spaces, not tabs, in the
        definition of this variable.

2010-06-12  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Remove a couple of unneeded conditionals from tests.

        * tests/forcemiss2.test: ... and this one.
        * tests/symlink2.test: Enable `errexit' shell flag, make test
        stricter, and skip it if symlink creation is not supported.
        * tests/postproc.test: Enable `errexit' shell flag, related
        changes, and a couple of unrelated cosmetic changes.
        * tests/recurs.test: Use the `configure.in' stub created by
        `./defs', rather than writing one from scratch.  Make grepping
        of Automake stderr slightly stricter.
        * tests/substtarg.test: Likewise.
        * tests/strip.test: Likewise, and move the call to `set -e'
        earlier (just after the inclusion of `./defs'). Also, make sure
        that the script installed by `make install-script' is equal to
        the original one.
        * tests/substref.test: Use the `configure.in' stub created by
        `./defs', rather than writing one from scratch.  Move the call
        to `set -e' earlier (just after the inclusion of `./defs').
        Avoid to explicitly export CC for configure (that's already done
        in ./defs).  Avoid potential problems with unpredictable make
        output.  Finally, make grepping of Makefile.in stricter.

        Modernize, improve and/or fix tests `pluseq*.test.
        * tests/pluseq5.test: Append to configure.in using cat with an
        here-doc, not using echo.
        * tests/pluseq10.test: Make sure that the captured output of
        `make' command is always displayed. Where possible, use $FGREP
        instead of grep (this change makes some checks slightly stricter).
        * tests/pluseq8.test: Enable `errexit' shell flag, with related
        changes.
        * tests/pluseq.test: Likewise.  Also, do not create useless dummy

        Testsuite: ensure verbose printing of captured stderr.
        * tests/acloca18.test: Print captured stderr before either failing
        or grepping it.  Be sure to send captured stderr to stderr, not to
        stdout.

        dummy source file.
        * tests/acoutpt2.test: Enable the `errexit' shell flag, and some
        related changes.  Do some cosmetic improvements in the generated
        `configure.in' file.

            Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Extend tests/README w.r.t. trailing `:' in test scripts.
        * tests/README (section "Writing test cases" subsection "Do"):
        Explain why apparently redundant trailing `:' and `Exit 0' in
        test scripts can indeed be useful.

2010-06-11  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Improve determination of PATH separator in bootstrap script.
        * bootstrap: Determine what the PATH separator is the same way
        autoconf does.

        Minor improvements in bootstrap script.
        * bootstrap: Consistently use two-spaces indentation.  Cosmetic
        improvement to comments.
        ($me): New variable, containing program basename.
        Prepend it to all error messages.

        Testsuite now works with BSD make in parallel mode.
        * tests/defs.in: Unset variables __MKLVL__ and MAKE_JOBS_FIFO,
        which are exported by BSD make when run in parallel mode, and
        which can confuse make processes spawned by our testsuite.
        This change fixes a lot of spurious failure when the testsuite
        is run with BSD make in parallel mode.

2010-06-09  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Modernize, improve and/or fix various test scripts.
        * tests/sanity.test: Rely on the `configure.in' stub created by
        `./defs', rather than writing one from scratch.

        the inclusion of `./defs', instead that later in the script.
        * tests/canon5.test: Avoid a useless `|| Exit 1' after a call to
        $AUTOMAKE, and improve the positioning of an $ACLOCAL call.
        * tests/exeext4.test: Use $FGREP instead of grep, where possible.
        Make auxiliary rules in the generated Makefile more silent.
        These changes make some checks slightly stricter.
        * tests/ext2.test: Call `Exit 1' if inclusion of `./defs' fails.
        * tests/gettext2.test: Place final `:' at the end of the script,
        rather than in the middle.

        plain `mv', just to be sure.

        changes.  Also, modernize the generated configure.in.
        * tests/cond9.test: Likewise.  Also, rely on the `configure.in'

        since that flag is already provided by $AUTOMAKE.
        * tests/mdate.test: Made stricter, by checking that Automake
        actually failed, and by making a stricter grep on the error
        message.  Also, set shell `errexit flag'.
        * tests/python2.test: Improved verbose messages.

        Make test `ammissing.test' stricter.
        * tests/ammissing.test: Fail if $ACLOCAL succeeds unexpectedly.

        * tests/mdate.test: Likewise.
        Prompted by Stefano Lattarini's change to discover.test.

        Improve ext.test semantics, avoid OpenBSD sh errexit issue.
        * tests/ext.test: Inside shell compound command, use
        `if $cmd; then Exit 1; fi' rather than `$cmd && Exit 1', to
        fix failure with OpenBSD sh introduced with last patch.
        Actually ensure that a rule for .EXT.o is created for each
        known extension EXT.

2010-06-06  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Make tests on user extensibility of silent-rules mode stricter.
        * tests/silent6.test: Made stricter w.r.t. the grepping of the
        output produced by `make'.
        * tests/silent7.test: Likewise.

        Tests on silent-mode for C/Libtool made stricter.
        * tests/silent.test: Made stricter w.r.t. the grepping of the
        output produced by `make'.
        * tests/silent2.test: Likewise.
        * tests/silent4.test: Likewise.
        * tests/silent9.test: Likewise.
        * tests/silent3.test: Likewise, and add a final `make distclean'
        command to keep it better in sync with tests/silent{4,9}.test.

        Improved test silent5.test.
        * tests/silent5.test: Remove by hand all generated C files after
        non-verbose builds, to ensure the following builds are clean.
        Try to clean and rebuild with the same verbosity and without
        removing generated sources in between, to check that this does
        not trigger a different set of rules.  Make grepping of make's
        output stricter.  Improved/added some comments.

        New tests for Automake silent-mode with Fortran.
        * tests/silentf77.test: New test.
        * tests/silentf90.test: Likewise.

        * tests/Makefile.am (TESTS): Updated accordingly.

        Relax tests on silent-rules to cater to overly verbose makes.
        * tests/silent.test: When testing silent builds, don't fail if
        make's output simply contains the `mv' substring, but only if
        it contains the `mv ' substring (note the trailing space).
        * tests/silent2.test: Likewise.

2010-01-24  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Fix silent-rules output for disabled dependency tracking.
        * lib/am/depend2.am [!%FASTDEP%]: Rework silent-rules variable
        expansion code to also work in the case where %AMDEP% expands
        to FALSE at config.status time, using new substitution string
        %VERBOSE-NODEP%.
        * automake.in (verbose_nodep_flag): New function, appending
        `@am__nodep@' to the verbose-variable name.
        (handle_languages): If dependencies are not disabled, use it to
        set %VERBOSE-NODEP%.
        * m4/depend.m4: Substitute am__nodep as '_no', so the second
        verbose-variable will always expand to an empty string, if
        dependencies are enabled.
        * tests/silent5.test: Also test --disable-dependency-tracking;
        also test per-target flags for non-C language files.
        * tests/silent9.test: New test, like silent4.test but disable
        dependency tracking.
        * tests/Makefile.am: Adjust.
        * NEWS, THANKS: Update.
        Report by Dmitry V. Levin <ldv@altlinux.org>.

2010-05-23  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Extend test on `nostdinc' automake option.
        * tests/nostdinc.test: Enable `errexit' shell flag.  Related and
        unrelated minor changes.  Make the grepping of the generated
        Makefile.in slightly stricter.  Generate and run configure, so that
        the generated Makefile can be grepped too.

2010-05-23  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Make gnupload portable to EBCDIC hosts.
        * lib/gnupload: Use literal newline as argument for 'tr' rather
        than \015, for EBCDIC hosts.  Also, avoid unportable nested
        double-quotes and backquotes.
        * THANKS: Update.
        Report from Eric Blake and Steve Goetze via gnulib.

2010-05-23  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Fix Autoconf version required by Automake's configure.
        Automake configure script used to tell that automake required
        autoconf 2.60 or later, but then it checked for autoconf >= 2.62,
        and if that was not found, it gave an error saying that Automake
        required configure 2.61a-341 or later.  This change should
        eliminate such inconsistencies.
        * configure.ac ($required_autoconf_version): New variable.
        Use it throughout.

2010-05-23  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Fix unportable sed script in maintainer-check test.
        * Makefile.am (sc_tests_Exit_not_exit): Rewrite sed script to
        not contain semicolon after 'b' or brace commands, for NetBSD.

        Wildcards are not portable to NetBSD make.
        * doc/automake.texi (Wildcards): Document portability issue.
        * tests/extra10.test, tests/extra11.test, tests/extra12.test:
        Require GNU make.

2010-05-23  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Make test for configure.in vs. configure.ac stricter.
        * tests/configure.test: Use a configure.in file that provokes
        an automake error, to ensure configure.ac is preferred.

        Avoid possible false negatives in dejagnu7.test.
        * tests/dejagnu7.test: Enable shell `errexit' flag.  Also, avoid
        unportable use of fgrep option `-e'.

        Fix conflnk3.test to work with Solaris/Heirloom Sh.
        * tests/conflnk3.test: Use `test -r FILE' and `test ! -r FILE'
        instead of respectively `test -e FILE' and `test ! -e FILE',
        since Solaris Sh doesn't grok the latter.  Do not SKIP the test
        if the shell doesn't support `test -e'.

2010-04-25  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Fix typo in manual.
        * doc/automake.texi (Simple Tests using parallel-tests): Add
        missing closing parenthesis.

        Fix leftover call to removed function macros_dump.
        * automake.in (read_main_am_file): Call variables_dump, not
        macros_dump.  Print actual error before list of variables.

2010-04-25  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Minor improvements in comments of test `silent3.test'.
        * tests/silent3.test: Tell to keep it in sync with `silent9.test'
        too.

2010-04-25  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        testsuite: ensure verbose printing of captured output.
        * tests/acloca14.test, tests/acloca18.test, tests/aclocal.test,
        tests/fort2.test, tests/help.test, tests/missing3.test,
        tests/missing6.test: Print captured stdout or stderr before
        grepping it.

2010-04-20  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Make test badopt.test stricter (by enabling `set -e').
        * tests/badopt.test: Add call to `set -e'.  Due to this change,
        an unexpected failure in the call to `$ACLOCAL' (whose outcome
        was previously unchecked) would cause the whole test to fail.
        Also, bumped the copyright years.

        Make test for configure.in vs. configure.ac stricter.
        * tests/configure.test: Use a configure.in file that provokes
        an automake error, to ensure configure.ac is preferred.

        Use `set -e' in confsub.test (avoids possible false negatives).
        * tests/confsub.test: Enable shell `errexit' flag, and related
        changes (this helps avoiding some possible minor false negatives).
        Also, bumped copyright years.

2010-04-20  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Fix -Werror handling for presence of configure.in and configure.ac.
        * lib/Automake/Variable.pm (Automake::Variable): Do not initialize
        $configure_ac at the global level, before command-line arguments
        have been parsed.
        (require_variables): Initialize it here.
        * tests/configure.test: New test.
        * tests/Makefile.am: Update.
        Report by Stefano Lattarini.

2010-04-20  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Avoid possible false negatives in confh5.test.
        * tests/confh5.test: Enable shell `errexit' flag, and bumped
        copyright years.  Due to this change, any unexpected failure
        in calls to $ACLOCAL, $AUTOMAKE, $AUTOCONF or $AUTOHEADER, or
        a failure in grepping expected text in output files should now
        cause the whole test to fail.

2010-04-17  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Fixed typo in POD documentation of Automake::Channels.
        * lib/Automake/Channels.pm: Fixed typo in POD documentation:
        @<...> was used instead of C<...>.

2010-04-14  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Refactor tests on Automake TESTS color output.
        * tests/color.test: Tests using the expect program moved out to...
        * tests/color2.test: ... this new file.
        * tests/Makefile.am (TESTS): Extended accordingly.

2010-04-12  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Fix typos in comments in test confh5.test
        * tests/confh5.test: Fix a couple of typos in comments.

        Avoid possible false negatives in canon-name.test.
        * tests/canon-name.test: Enable shell `errexit' flag.  Improve
        test description.

2010-04-11  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Fix per-Makefile.am setting of -Werror.
        Before this patch, 'AUTOMAKE_OPTIONS = -Werror' in one
        Makefile.am would carry over to other Makefile.am files
        treated afterwards by the same thread, causing inconsistent
        and unstable exit status values.
        * lib/Automake/Channels.pm (dup_channel_setup)
        (drop_channel_setup): Save and restore the setting of
        $warnings_are_errors.
        * tests/werror3.test: New test.
        * tests/Makefile.am: Adjust.
        * NEWS: Update.

2010-04-11  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Bugfix in confh5.test w.r.t. Solaris/Heirloom Sh.
        * tests/confh5.test: In the generated Makefile.am: do not use
        `test ! -e FILE' to check for the non-existence of a file, since
        that is not supported by Solaris/Heirloom Sh.

        Make test `aclocal3.test' stricter.
        * tests/aclocal3.test: Add call to `set -e'.  Fail if $ACLOCAL
        succeds unexpectedly.

        Add tests checking that symlinks are resolved by `make dist'.
        * tests/distlinks.test: New test.
        * tests/Makefile.am (TESTS): Updated accordingly.
        Suggested by observations from Ralf Wildenhues.

2010-04-11  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Use -9 for maximum xz compression with dist-xz.
        * lib/am/distdir.am (dist-xz, dist, dist-all): Pass -9 to xz.
        * NEWS, THANKS: Update.
        Report by Pavel Sanda.

2010-03-30  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Avoid an unportable use of `$status' shell variable.
        * Makefile.am (path-check): Don't use the `$status' shell variable
        in the target's rules, as it's special in Zsh (equivalent to `$?',
        and readonly).

        Avoid another use of `chmod -R'.
        * Makefile.am (path-check): To be safe, do not use `chmod -R' on
        $(distdir) before removing it (as Solaris `chmod -R' touches
        symlink targets).  Instead, use the cleanup strategy used in
        distdir.am.

2010-03-28  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Remove uses of @acronym and @sc.
        * doc/automake.texi (Public Macros, Limitations on File Names):
        Remove all usage of @acronym and @sc in the manual.
        Suggested by Karl Berry.

2010-03-13  Karl Berry  <karl@freefriends.org>

        GNU hello uses fdl.texi, not gpl.texi.
        * doc/automake.texi (Texinfo): Adjust example to upstream
        change.

2010-03-06  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Formatting cleanups in macro comments.
        * automake.in, lib/Automake/Channels.pm,

2010-03-04  Stefano Lattarini  <stefano.lattarini@gmail.com>
            Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Avoid generation of `tests/defs-p' file.
        * tests/defs.in: In the generated `configure.in' snippet: call
        `AM_INIT_AUTOMAKE' with the `parallel-tests' option if the shell
        variable `parallel_tests' is set to `yes'.
        * tests/Makefile.am (defs-p): Target removed.
        (check_SCRIPTS): Removed `defs-p'.
        (clean-local-check): Do not unlink `defs-p' anymore.
        ($(parallel_tests)): Transformation rules for the test scripts
        adjusted.
        * tests/gen-parallel-tests: Selection rules for the test
        scripts adjusted.
        * tests/parallel-tests.test: Set `$parallel_tests' to `yes'
        then include `./defs' (rather than simply including `./defs-p').
        * tests/parallel-tests2.test: Likewise.
        * tests/parallel-tests3.test: Likewise.
        * tests/parallel-tests4.test: Likewise.

        Adjusted the parts referring to tests checking `parallel-tests'
        behaviour.  Some other minor related improvements.
        * tests/.gitignore (defs-p): Removed.

2010-03-04  Stefano Lattarini  <stefano.lattarini@gmail.com>

        Remove redundant unset of variable TESTS from some test scripts.
        * tests/color.test: Do not unset the `TESTS' variable, as it's
        already unset in the `defs' file.
        * tests/check5.test: Likewise.
        * tests/check8.test: Likewise.
        * tests/check9.test: Likewise.

        * tests/parallel-tests7.test: Likewise.

2010-02-22  Karl Berry  <karl@gnu.org>

        Improve help message of mdate-sh.
        * mdate-sh: mention actual output format in help message.

        EXTRA_DIST when $builddir != $srcdir.
        * tests/Makefile.am (TESTS): Updated accordingly.
        Necessity of these new tests suggested by Braden McDaniel

            Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Fix exit status of signal handlers in shell scripts.
        The value of `$?' on entrance to signal handlers in shell scripts
        cannot be relied upon, so set the exit code explicitly to
        128 + SIG<SIGNAL>.
        * lib/am/check.am (am__check_pre): Use `exit 143' in signal handler.
        * lib/elisp-comp: Likewise.
        * lib/install-sh: Likewise.
        * lib/ylwrap: Likewise.  Also, fix script to trap signal 13, not 3.

        Slighty improve tests acoutbs.test and acoutbs2.test.
        * tests/acoutbs2.test: Enable `errexit' shell flag.  Check that
        autoconf and configure work, that the file `zot' is created by
        configure, and that no file containing a backslash in its name is
        created.
        * tests/acoutbs.test: Likewise, plus updated copyright years.

        Fix test acoutbs2.test.
        * tests/acoutbs2: In the generated configure.in: add proper calls
        to AC_INIT and AM_INIT_AUTOMAKE, and remove explicit definition of
        PACKAGE and VERSION. Add a call to aclocal before calling automake.
        Updated copyright years.
        * tests/Makefile.am (XFAIL_TESTS): Removed acoutbs2.test.

        Add forgotten test scripts to $(TESTS).
        * tests/Makefile.am (TESTS): Added test scripts present on the
        filesystem, which were erroneously left out from $(TESTS):
