Problem reported by Gerd Möllmann (Bug#68464).
* .gitignore: Ignore files in exec that are now copied from build-aux.
* admin/merge-gnulib (avoided_flags): Instead of clearing
autom4te.cache here ...
* autogen.sh (do_git): ... clear it here.
Use config.guess, config.sub and install-sh from
the Emacs repository, as they are more likely to be up to date.
This avoids unnecessary differences among different builders,
and avoids unnecessary ‘git diff’ output after autogen.sh.
Also, copy these files from build-aux to exec since there
should be no difference between the two copies.
* exec/config.guess, exec/config.sub, exec/install-sh:
Remove from repository, as autogen.sh now copies them from build-aux.
This should help avoid further Autoconf portability gotchas such as
the one recently fixed in 2022-06-27T04:26:01Z!meyering@fb.com.
* autogen.sh (autoconf_min): Adjust pattern to match
updated configure.ac.
* configure.ac: Quote arguments more consistently,
as per the Autoconf manual.
Restore lines saying "Maintainer: emacs-devel@gnu.org" when there is
no special maintainer for a file. Although this wasn't documented
it was common practice and removing the lines didn't have consensus.
5d24af8 Remove from docs references to obsolete MULE variables
2bdc419 Do potentially destructive operations in prepare-commit-msg
# Conflicts:
# src/search.c
* build-aux/git-hooks/prepare-commit-msg: If someone occasionally puts
Signed-off line, it will likely get there through -s option of git.
Exploit this fact to abort before a user got a chance to type commit
message. (Bug#35368)
Most of this change is to boilerplate commentary such as license URLs.
This change was prompted by ftp://ftp.gnu.org's going-away party,
planned for November. Change these FTP URLs to https://ftp.gnu.org
instead. Make similar changes for URLs to other organizations moving
away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and
fsf.org when this works, as this will further help defend against
man-in-the-middle attacks (for this part I omitted the MS-DOS and
MS-Windows sources and the test tarballs to keep the workload down).
HTTPS is not fully working to lists.gnu.org so I left those URLs alone
for now.
Its /bin/sh builtin ‘test’ command does not support -e.
* autogen.sh, build-aux/git-hooks/pre-commit:
* build-aux/gitlog-to-emacslog, make-dist:
Use test -r, not test -e.
Apparently Gitlab doesn’t create .git/hooks, like regular Git does.
Problem reported by Ted Zlatanov in:
http://lists.gnu.org/archive/html/emacs-devel/2017-08/msg00380.html
* autogen.sh (git_sample_hook_src): New function. Use it to work
even if .git/hooks or its samples do not exist.
* autogen.sh (get_version): Simplify and make more reliable
by using expr rather than echo | sed. Check exit status of program.
Run program in subshell in case it cannot be executed.
(check_version): Check exit status of command rather than its output.
Check return status of get_version.
* autogen.sh (get_version): Check return status of "--version".
(check_version): Try to distinguish between a missing tool
and a broken one. (Bug#27288)
This fixes some minor problems introduced in the recent switch to GNU
Make, discovered by further testing. Without some of these changes
'make -j' would sometimes have race conditions caused by missing
dependencies. (Bug#26100)
* .gitignore: Remove src/stamp-h.in, src/stamp-h1.
* Makefile.in ($(MAKEFILE_NAME)): Depend on configure, not
src/config.in, since the former's timestamp now represents
the latter's.
($(srcdir)/configure): Use plain ./autogen.sh, for consistency
with other autogen.sh invocations.
($(srcdir)/src/stamp-h.in):
Remove rule, as this file is no longer created.
* Makefile.in (top_distclean):
* src/Makefile.in (bootstrap-clean):
No need to remove stamp-h1, as that was an Automake byproduct
and Automake is no longer in use.
* lib/Makefile.in, src/Makefile.in:
(AUTOCONF_INPUTS, $(top_srcdir)/configure): Remove.
(../config.status, Makefile): Simplify by limiting dependencies
to files we care about and files in the repository, and by
using just one file to represent the timestamps on multiple
targets updated by the same rule.
* autogen.sh: Do not create or use src/stamp-h.in.
Instead, have 'find' test the two output files directly.
Emacs assumes GNU Make, and GNU Make has much of the functionality of
Automake built-in. The Emacs build process uses Automake primarily
because Emacs uses some Gnulib code and Gnulib formerly required
Automake. Now that Gnulib no longer requires Automake, Emacs can
stop using Automake and this should simplify Emacs maintenance
in the future (Bug#26100). Although this patch may look long, most of
it is generated automatically: the changes to build-aux/config.guess,
build-aux/config.sub, build-aux/install-sh, and lib/gnulib.mk.in are
all done by admin/merge-gnulib.
* .gitignore: Remove build-aux/ar-lib, build-aux/compile,
build-aux/config.guess, build-aux/config.sub, build-aux/depcomp,
build-aux/install-sh, build-aux/missing, and lib/Makefile.in,
as they are no longer built by autogen.sh.
Add lib/gnulib.mk, as it is now built by 'configure'.
Remove nt/gnulib.mk, as it is no longer built by 'make'.
* INSTALL.REPO, README, admin/make-tarball.txt:
Remove mention of Automake.
* Makefile.in (AUTOCONF, AUTOMAKE, AUTOHEADER, ACLOCAL, lib)
(AUTOCONF_INPUTS, ACLOCAL_PATH, ACLOCAL_INPUTS)
($(srcdir)/aclocal.m4, AUTOMAKE_INPUTS)
($(srcdir)/lib/Makefile.in, $(srcdir)/nt/gnulib.mk, am--refresh):
Remove.
($(MAKEFILE_NAME)): Depend on lib/gnulib.mk.in.
($(srcdir)/configure, $(srcdir)/src/stamp-h.in)
($(srcdir)/src/config.in):
Use autogen.sh instead of doing it by hand.
* admin/merge-gnulib (AVOIDED_MODULES, avoided_flags)):
New vars, to simplify processing of avoided modules.
(GNULIB_TOOL_FLAGS): Move --avoid flags into AVOIDED_MODULES.
Add --gnu-make, and change makefile name to gnulib.mk.in.
Copy config.guess, config.sub, and install-sh too, since
Automake no longer does that for us.
* admin/notes/copyright:
* admin/update_autogen (genfiles):
Update list of files.
Remove hack for nt/gnulib.mk, a file that is no longer needed.
* autogen.sh (progs): Remove Automake.
(automake_min): Remove.
Build aclocal.m4 so that autoreconf need not use aclocal.
* build-aux/config.guess, build-aux/config.sub:
* build-aux/install-sh:
New files, copied from Gnulib. These are now updated by
admin/merge-gnulib instead by autogen.sh.
* configure.ac (AC_PROG_MAKE_SET, ACLOCAL_PATH, AM_CONDITIONAL):
Remove.
(AM_INIT_AUTOMAKE, AM_SILENT_RULES): Remove call.
(AC_PROG_CC_C_O): Call this instead of AM_PROG_CC_C_O.
(BUILDING_FOR_WINDOWSNT, HYBRID_MALLOC_LIB): Remove; no longer needed.
(--disable-silent-rules): New option, since Automake no longer
does this for us.
(AM_V, AM_DEFAULT_V): Set unconditionally, and do not bother
with AM_SUBST_NOTMAKE.
(AC_PROG_INSTALL): Add call.
(MAKEINFO): Do not bother with the 'missing' program.
(MAKEINFO, SYSTEM_TYPE): AC_SUBST.
(AC_CONFIG_FILES): Add Makefile, lib/gnulib.mk.
(SUBDIR_MAKEFILES): Remove duplication.
* lib/Makefile.am: Remove, replacing with:
* lib/Makefile.in: New file, with the old Makefile.am contents
and with the following changes:
(AUTOMAKE_OPTIONS, BUILT_SOURCES, CLEANFILES, EXTRA_DIST)
(MOSTLYCLEANDIRS, MOSTLYCLEANFILES, noinst_LIBRARIES, SUFFIXES)
(AM_CFLAGS, DEFAULT_INCLUDES, libegnu_a_SOURCES, libegnu_a_LIBADD)
(EXTRA_libegnu_a_SOURCES, libegnu_a_SHORTNAME, libegnu_a_CPPFLAGS):
Remove.
(VPATH, abs_top_builddir, top_builddir, top_srcdir, all, AM_V_AR)
(AM_V_CC, AM_V_GEN, AM_V_at, DEPDIR, DEPFLAGS, MKDEPDIR, SYSTEM_TYPE)
(libgnu.a, libegnu.a, ETAGS, $(ETAGS), tags, TAGS, clean)
(mostlyclean, distclean, bootstrap-clean, maintainer-clean):
New macros and rules, since Automake no longer does them.
Include ../nt/gnulib-cfg.mk if SYSTEM_TYPE is windows-nt,
instead of including ../nt/gnulib.mk if BUILDING_FOR_WINDOWS_NT.
Include dependency files if AUTO_DEPEND.
(ALL_CFLAGS, AUTOCONF_INPUTS, libgnu_a_OBJECTS, libegnu_a_OBJECTS):
New macros.
(bootstrap-clean): Depend on distclean, not maintainer-clean,
and remove gnulib.mk.
(AUTOCONF_INPUTS, $(top_srcdir)/configure, ../config.status, Makefile):
New macros and rules, copied from ../Makefile.in.
($(libegnu_a_OBJECTS), $(libgnu_a_OBJECTS)): Depend on BUILT_SOURCES.
(.c.o, e-%.o): New generic rules.
* lib/gnulib.mk: Remove.
* lib/gnulib.mk.in: New file, which is built by autogen.sh
and contains much of what used to be in lib/gnulib.mk.
* m4/gnulib-common.m4: Copy from gnulib.
* make-dist: Do not distribute build-aux/compile, build-aux/depcomp,
build-aux/missing, build-aux/ar-lib, lib/Makefile.am, nt/gnulib.mk,
nt/gnulib-modules-to-delete.cfg. Distribute lib/Makefile.in,
lib/gnulib.mk.in, and nt/gnulib-cfg.mk instead.
* nt/Makefile.in (AM_V_GEN, am__v_GEN_, am__v_GEN_0)
(am__v_GEN_1, ${srcdir}/gnulib.mk): Remove.
* nt/gnulib-cfg.mk: New file, which supersedes ...
* nt/gnulib-modules-to-delete.cfg: ... this file, which is removed.
* src/Makefile.in (ACLOCAL_INPUTS): Remove.
(AUTOCONF_INPUTS): Merge ACLOCAL_INPUTS into it.
($(top_srcdir)/configure, ../config.status, config.in Makefile):
Defer to parent Makefile.
* autogen.sh: Do both autoconf and git setup when invoked
as ‘./autogen.sh autoconf git’. Avoid unnecessary newline in chatter.
Mention new --no-check option in usage message. (Bug#25359)
* autogen.sh (gnulib.mk): Make the Sed script more portable.
* nt/Makefile.in (${srcdir}/gnulib.mk): Adapt the Sed command to
the changes in autogen.sh.
Problem reported by Sam Steingold (Bug#25347).
* autogen.sh: Don't assume 'sed -f-' reads a script from stdin, as
POSIX does not require it and it does not work on Darwin.
This was proposed by Paul Eggert <eggert@cs.ucla.edu>,
with the purpose of avoiding manual maintenance of
nt/gnulib.mk.
* nt/gnulib-modules-to-delete.cfg: New file.
* nt/Makefile.in (AM_V_GEN, am__v_GEN_, am__v_GEN_0)
(am__v_GEN_1): New variables.
(${srcdir}/gnulib.mk): Rules to generate gnulib.mk from
lib/gnulib.mk and list of modules in gnulib-modules-to-delete.cfg.
* make-dist (nt): Add gnulib-modules-to-delete.cfg to the list of
files to link.
* configure.ac (GNULIB_MK): Compute the value according to $opsys.
* autogen.sh: Create nt/gnulib.mk if it doesn't exist, before
running autoreconf.
* Makefile.in (gnulib_mk): New variable.
($(srcdir)/nt/gnulib.mk): Rule to produce it.
(AUTOMAKE_INPUTS): Use $(gnulib_mk) instead of a literal file
name.
* .gitignore: Add nt/gnulib.mk.
* src/w32.c (acl_errno_valid): Implement it here, as we no longer
build the acl-permissions module from Gnulib.
