Since 2.72[abcde] did not get widely used, squash all the NEWS entries
since 2.71 together, and delete things that were only of interest to
people going from a,b,c to d to e. Finalize the release date.
* cfg.mk (local-checks-to-skip): Add sc_unportable_grep_q, which has
too many false positives to bother with; for instance, it triggers
on autoconf.texi’s discussion of why grep -q is unportable, and on
the code in maint.mk that implements the check!
(old_NEWS_hash): Update for commit b751bf4949,
which fixed spelling errors in old NEWS.
* doc/autoconf.texi: Remove a doubled word.
* lib/autoconf/programs.m4: Remove a space immediately before a tab.
* lib/m4sugar/m4sh.m4 (_AS_IF): Rephrase documentation to avoid saying
“if IF-FALSE” which triggers the prohibit_doubled_word check.
Matching the commits on the release branch:
* NEWS: Bring over record of release notes.
* .prev-version: Record previous version.
* cfg.mk (old_NEWS_hash): Auto-update.
Using HTTP::Tiny to talk to the network, instead of wget, means that
we can make just one TCP connection to git.savannah.gnu.org to do the
whole job, which is quite a bit faster. It should also be more
robust against weird characters in filenames / URLs and stuff.
The script has a higher requirement for Perl than is the standard in
autoconf -- 5.14 (first version with HTTP::Tiny), with IO::Socket::SSL
installed -- but that’s ok, I hope, because it’s maintainer-only and
not installed.
fetch.sh was the sole user of move-if-change, and the Perl script does
that job itself, but I left move-if-change in build-aux and on the fetch
list anyway, in case we discover another use for it in the future.
* build-aux/fetch.sh: Replace with...
* build-aux/fetch.pl: ... reimplementation in Perl.
* cfg.mk (fetch): Update to match.
‘make fetch’ pulls the files maintained by Automake from gitweb, so we
always get the HEAD revision at the time of the operation. The files
maintained by Gnulib, on the other hand, are just copied from whatever
local gnulib checkout you happen to have on your hard drive at the
time, which might not have been updated recently and might not even be
checked out from gnulib trunk.
This patch makes us use the same logic for Gnulib that we do for
Automake. It also pulls all of the code out of cfg.mk to a separate
shell script. The lists of files to update from each repository are
also moved to that file.
* build-aux/fetch.sh: New script. Lists of files to fetch from
Gnulib and Automake are now kept here.
* cfg.mk (fetch): Run fetch.sh, it does all the work.
(gnulib-update, autom4te-update, WGETFLAGS, automake_gitweb)
(autom4te_files, move_if_change): Delete.
This macro was replaced by AC_CONFIG_HEADERS many years ago (before
the beginning of the VCS history) and isn’t even documented, but we
never got around to making autoupdate notice it. Problem reported
*in 2006* by jensseidel@users.sf.net.
There was one use of AC_CONFIG_HEADER in our source tree, which is
converted. Also, to avoid confusing people reading old NEWS or TODO
entries, all mentions of AC_CONFIG_HEADER therein are also replaced
with AC_CONFIG_HEADERS.
* lib/autoconf/status.m4 (AC_CONFIG_HEADER): Make an AU_ALIAS for
AC_CONFIG_HEADERS.
There are two errors caught by make syntax-check currently.
First, the recent make update-copyright
(d78a7dd95f) missed autoconf.texi, I
think because there are a bunch of .texi files in doc/ whose copyright
years should *not* be updated (e.g. standards.texi, fdl.texi) and the
exclusion pattern is too broad. I can't actually *find* the exclusion
pattern in the twisty maze of .mk files, all alike, so I just manually
updated autoconf.texi.
Second, it objects to an edit to an old section of NEWS. This is
because of d3dcd5895d, which is a
legitimate change (replacing http:// with https:// in a URL) so the
correct action is to change old_NEWS_hash to match.
* doc/autoconf.texi: Update copyright year.
* cfg.mk (old_NEWS_hash): Update to acknowledge commit
d3dcd5895d.
Done via 'make update-copyright', since all files are effectively
modified and distributed this year via public version control.
* all files: Update copyright year.
Rather than reading it dynamically from the ChangeLog -- that,
remember, is only a dummy in a Git checkout! To avoid risking
the definition to get out-of-sync, let's enhance the maintainer
target 'update-copyright' to update it automatically (the same
way it's done in the Automake build system).
* configure.ac (RELEASE_YEAR): New AC_SUBST'd variable.
* cfg.mk (update-release-year): New maintainer-specific target
to automatically update the value of that variable.
(update-copyright): Depend on the new target.
* bin/local.mk (RELEASE_YEAR): Drop definition.
(edit): Simplify quoting of $(RELEASE_YEAR).
* lib/Makefile.am (RELEASE_YEAR): Drop definition.
(m4sugar/version.m4): Simplify quoting of $(RELEASE_YEAR).

That file has been removed in the master branch of Automake, since
Automake 1.14 will remove support for 'configure.in' as a name for
Autoconf input files. See commits 'v1.13-17-gbff57c8' and
'v1.13-21-g7626e63' in the Automake repository.
* cfg.mk (autom4te_files): Remove 'Autom4te/Configure_ac.pm'.

Automake 1.13 will be changing the semantics of 'missing'; maintaining
our own copy in version control risks problems if our version does
not match automake's expectations. As a result, gnulib no longer
mirrors 'missing'. Furthermore, gnulib originally added the
'elisp-comp' module with the explanation that autoconf uses it, but
we don't use it anywhere other than the manner in which automake
will byte-compile our .el files; since we don't document the script,
we should be just fine using the version that was installed by automake.
See more discussion in the thread starting here:
https://lists.gnu.org/archive/html/automake-patches/2012-06/msg00154.html
* cfg.mk (gnulib-update): Drop files installed by automake and no
longer present in gnulib.
* .gitattributes: Delete references to files not in git.
Upstream gnulib maint.mk improvements caught a few issues we
should fix, as well as a few issues in files we copy from
other sources that we will just ignore here.
* doc/autoconf.texi (Generic Programs, Special Shell Variables)
(Limitations of Builtins): Use references correctly.
* cfg.mk
(exclude_file_name_regexp--sc_prohibit_undesirable_word_seq)
(exclude_file_name_regexp--sc_useless_cpp_parens): Add exemptions.
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
with Automake.
* lib/Autom4te/Struct.pm: Delete.
* lib/Autom4te/Makefile.am (dist_perllib_DATA): Don't list it
anymore.
* cfg.mk: Don't sync it with the Automake repository anymore.
* lib/Autom4te/Request.pm: Use 'Class::Struct' instead of
'Autom4te::Struct'.
Many of the .x-sc_* exemptions were no long necessary. Remove those
files and instead, provide exemptions via variable definitions in
cfg.mk to address the few remaining exceptions.
* .x-sc_prohibit_atoi_atof: Remove file.
* .x-sc_space_tab: Likewise.
* .x-sc_sun_os_names: Likewise.
* .x-sc_trailing_blank: Likewise.
* .x-sc_two_space_separator_in_usage: Likewise.
* .x-sc_useless_cpp_parens: Likewise.
* cfg.mk: Add minimal exemptions.
* cfg.mk: Add minimal exemptions.
* doc/standards.texi (Standard C): Address the sole useless-cpp-parens
violation in this file:
-#if defined (__STDC__) || defined (WINDOWSNT)
+#if defined __STDC__ || defined WINDOWSNT
With that, the only remaining offender is config.guess, whose name
is now listed in cfg.mk.
Suggested by Eric Blake.
* cfg.mk (local-checks-to-skip): List failing tests, so we skip
them, for now.
(old_NEWS_hash): Update.
* doc/autoconf.texi: Per suggestion from Eric Blake, obfuscate
the first word of "Filesystem Hierarchy Standard" as File@/system
so it continues to render as one word, yet doesn't trigger the
syntax-check prohibition.
* cfg.mk (gnulib-update): Add them to the list.
* maint.mk: Update from gnulib.
* build-aux/gitlog-to-changelog: Likewise.
* build-aux/useless-if-before-free: New file, from gnulib.
* doc/gnu-oids.texi: Update.
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.
* lib/Autom4te/Getopt.am: The master copy of this file has
been moved to the Automake repository (see Automake commit
'v1.11-662-g52246cc' 2012-01-18, "cmdline parsing: move into
a dedicated perl module"). So we now we sync it from there,
by listing it ...
* cfg.mk (autom4te_files): ... in this variable.
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.
* README: Copy coreutils wording for allowing copyright year
ranges.
* cfg.mk (UPDATE_COPYRIGHT_USE_INTERVALS): Now that GNU Coding
Standards permit it, prefer shorthand copyright.
* .x-update-copyright: Exempt an imported file.

* maint.mk (PREV_VERSION_REGEXP): New macro, missed when
backporting update-NEWS_hash from gnulib.
* cfg.mk (old_NEWS_hash): Correctly generate.
* build-aux/gendocs.sh: Temporarily break sync from upstream, to
avoid including spurious directories in info source tarball.
