maint: drop bz2 tarball
|
|
At 2.68b, I asked whether anyone would miss .gz and .bz2 formats.
|
|
Consensus was overwhelming that .gz still holds a place in people's
|
|
hearts, in spite of .xz compressing to smaller files, but no one
|
|
was able to make a convincing argument for .bz2.
|
|
|
|
* configure.ac (AM_INIT_AUTOMAKE): Drop bzip2; xz wins hands down.

AC_INIT: remove a transitional warning
|
|
On bi-arch systems (such as x86 / x86_64) it is often necessary to pass
|
|
the --host option together with an appropriate value for CC. But this
|
|
triggers a warning:
|
|
|
|
$ ./configure --host=i686-pc-linux-gnu CC="gcc -m32 -march=i586"
|
|
configure: WARNING: if you wanted to set the --build type, don't use --host.
|
|
If a cross compiler is detected then cross compile mode will be used
|
|
..
|
|
|
|
This warning was introduced on 2000-06-30, in commit
|
|
<http://git.savannah.gnu.org/gitweb/?p=autoconf.git;a=commitdiff;h=cb2e761b8e1181f97e8e09d85526bd22078433db>
|
|
with the remark "Re-enable the old behavior of --host and --build."
|
|
|
|
This warning was meant to warn users about a changed semantics of
|
|
--build and --host. This change is now 12 years in the past; users
|
|
have had enough time to learn it. I therefore suggest to remove the
|
|
warning.
|
|
|
|
I've done lots of cross and bi-arch compilations in the last 10 years,
|
|
all with --host and without --build, and have never observed a problem
|
|
with it, except for the warning. Simply relying on config.guess is sufficient.
|
|
|
|
* lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Don't warn if --host
|
|
given without --build.

maint: drop syncing with Automake::Struct
|
|
The module Automake::Struct has been removed in automake master
|
|
branch (with yesterday's commit v1.11-2055-g74a7f49 "maint: drop
|
|
'Automake::Struct' module"): since Automake now requires Perl 5.6,
|
|
that module has become obsolete, being basically just a backport
|
|
of Perl 5.6's 'Class::Struct' to Perl 5.5. With this change, we
|
|
follow suite in Autoconf, which syncs some of its internal modules
|

tests: fix spurious failure due to Solaris XPG4 sh bug
|
|
On Solaris 10, the /usr/xpg4/bin/sh shell seems unable to execute
|
|
a shell script named 'script':
|
|
|
|
$ touch script
|
|
$ /bin/sh script; echo status: $? # As expected.
|
|
status: 0
|
|
$ /usr/xpg4/bin/sh script; echo status: $? # Weirdness follows.
|
|
/usr/xpg4/bin/sh: script: cannot execute
|
|
status: 1
|
|
|
|
This was causing a spurious testsuite failure for users which have
|
|
/usr/xpg4/bin in $PATH before /bin and /usr/bin. Fix that.
|
|
|
|
* tests/m4sh.at (Configure re-execs self with CONFIG_SHELL): Rename

m4sh: require that 'test -x' works
|
|
4.3BSD is no longer a reasonable portability target; and we are
|
|
pretty sure that these days we can find at least one shell on any
|
|
platform that supports 'test -x'. Drop a horribly unsafe use of
|
|
eval as a result. :)
|
|
|
|
Libtool still uses $as_executable_p without so much as calling
|
|
either AS_TEST_X or AS_EXECUTABLE_P; even though the latter has
|
|
existed, although undocumented, since at least 2.59; furthermore,
|
|
libtool uses it in a context where filtering out directories

would have been desirable. Shame on them.

maint: make position of gnulib checkout configurable
|
|
Some gnulib-related tools (most prominently, the gnulib-provided
|
|
'bootstrap' script) allow the user to define the position of his
|
|
gnulib's repository checkout through the use of the 'GNULIB_SRCDIR'
|
|
environment variable. We should do the same, for consistency and
|
|
to easily support slightly unusual layouts in developers' source
|
|
trees.
|
|
|
|
* cfg.mk (gnulib_dir): Define to "$GNULIB_SRCDIR" if that's set,
|
|
and to default value of "'$(abs_srcdir)'/../gnulib" otherwise.
|
|
Update comments.

build: fix automake error due to missing ChangeLog
|
|
Apparently, Automake does not accept the '$(srcdir)/ChangeLog'
|
|
target in Makefile.am as a declaration that ChangeLog is
|
|
automatically generated (and thus does not need to exist at
|
|
automake time). One has to use a *literal* 'ChangeLog' target.
|
|
|
|
Problem introduced in commit v2.68-118-g6ed5195 of 2012-01-17,
|
|
"maint: generate ChangeLog from git log".
|
|
|
|
* Makefile.ma ($(srcdir)/ChangeLog): Renamed ...
|
|
(ChangeLog): ... to this.

in the new Autom4te::Getopt module. This will make it simpler

|
now, Automake).
|

* lib/Automake/Makefile.am (dist_perllib_DATA): Add the new

tests: avoid spurious failure for each gnu-fortran-using test
|
|
The tests compare pre- and post-run lists of envvars, which must
|
|
be the same, modulo a list of known, filtered-out exceptions.
|
|
However, when running fortran-checking tests with GNU fortran, each
|
|
would fail due to the post-run addition of the GFC symbol added in
|
|
v2.68-97-gbd962ac.
|
|
* tests/local.at (AT_CHECK_ENV): Add GFC to the list of symbols
|
|
that we ignore in pre-/post-run environment diffs.

maint: generate ChangeLog from git log
|
|
Following the practice set by various other GNU projects, we start
|
|
to automatically generate the ChangeLog file from the git commit
|
|
messages. This will avoid duplication (as the ChangeLog entries
|
|
were always inserted both in the git commit message and in the
|
|
version-controlled ChangeLog file), and potential problems with
|
|
spurious merge conflicts (which, although greatly mitigated by
|
|
Bruno Haible's `git-merge-changelog' helper program, have never
|
|
been completely solved).
|
|
|
|
* ChangeLog: Moved ...
|
|
* ChangeLog.3: ... to this.
|
|
* build-aux/gitlog-to-changelog: New script, synced from gnulib.
|
|
* cfg.mk (gnulib-update): Also sync gitlog-to-changelog.
|
|
* Makefile.am (gen-ChangeLog): New .PHONY rule, generate the
|
|
ChangeLog for distribution.
|
|
(dist-hook): Depend on it.
|
|
($(srcdir)/ChangeLog): New dummy rule, to pacify automake "gnu"
|
|
strictness. Creates a dummy ChangeLog, that will be overridden
|
|
by the proper one at distribution time.
|
|
(gen_start_date): New variable, the date starting from which the
|
|
git log entries are to be copied in the generated ChangeLog.
|
|
(EXTRA_DIST): Add ChangeLog.3 and gitlog-to-changelog.
|
|
* configure.ac (AC_CONFIG_SRCDIR): Use 'lib/autoconf/autoconf.m4'
|
|
instead of 'ChangeLog' as the sentinel file.
|
|
* .gitignore: Add ChangeLog.
