* maint: automate creation of release tagEric Blake2016-12-313-23/+29
| | | | | | | | | | | | The gnulib makefile was already set up to automate things with 'make release ...', but we were still doing things by hand, and thereby risking missing some steps. * m4/gnulib-cache.m4 (gl_MODULES): Import do-release-commit-and-tag. * gnulib: Update, for latest version of the script. * HACKING: Mention its use.

* maint: generate ChangeLog from git commitsEric Blake2016-12-316-104/+50
| | | | | | | | | | | | | | | | | | | | | | Follow the practice set in numerous other GNU projects, where the ChangeLog (since 2015) is generated from git commit messages. This avoids duplication or subtle differences between the two, as well as making it easier to merge patches across branches (as good as Bruno Haible's 'git-merge-changelog' helper program is, it still doesn't handle cross-branch cherry-picks very well). * ChangeLog: Move... * ChangeLog-2014: ...to this. * Makefile.am (EXTRA_DIST): Ship renamed file. (gen-ChangeLog): New rule, copied mostly from coreutils. (dist-hook): Generate the ChangeLog. * m4/gnulib-cache.m4 (gl_MODULES): Import gitlog-to-changelog. * .gitignore: Ignore ChangeLog. * .gitattributes: Likewise. * HACKING: Reword to match new procedure, and simplify by referring to an external description of ChangeLog style.

* maint: make silent builds the defaultEric Blake2016-12-312-0/+5
| | | | | | | | | | | | The user still has full control over verbosity levels, both setting their per-project defaults at configure time (or even in a config.site file), as well as a per-run override. But these days, most projects are defaulting to silent rules without user intervention. * configure.ac (AM_SILENT_RULES): Add, to match what most projects are doing these days.

* maint: release no longer creates a diff fileEric Blake2016-12-312-5/+6
| | | | | | | | | Ever since commit f1cf390 (1.4.14 release), we no longer create diff files as part of the release process. These days, it is assumed that it is easier to download a fresh tarball rather than to try and use a diff file to patch an older tarball. Signed-off-by: Eric Blake <eblake@redhat.com>
* doc: drop obsolete @setcontentsaftertitlepageEric Blake2016-12-302-3/+5
| | | | | | | | | | | | | | | | texinfo 6.1 complains (during 'make dvi'): /home/eblake/m4-1.4/doc/./m4.texi:9: @setcontentsaftertitlepage has been remove d as a Texinfo command; move your @contents command if you want the contents af ter the title page.. It turns out that eliminating the command has no effect - modern tools correctly emit the contents in-place, right after the title page, so it was leftover cruft from an older time. * doc/m4.texi: Satisfy newer texinfo.

| | | | | | | | | | | | | | | | | | Dagobert Michelsen reported that in a setup that uses git to track patches on top of the distributed tarball, we ended up having configure defaults that did not play nicely with the Sun Studio 12.3 compiler. Gnulib has fixed the problems with detecting (un-)supported compiler flags, and additionally we can use a better witness file of whether we are likely to be a developer where it is worth enabling warnings by default. * gnulib: Update to latest gnulib. * configure.ac (gl_WARN_ADD): Drop flags now guaranteed by gnulib.

* build: avoid test failure on HPUXEric Blake2013-03-152-0/+13
| | | | | | | | | | | | | | | | | | | | | | POSIX permits implementations to open fd 0, 1, and 2 on exec(), even when the user tried to close them. HPUX-11.23 is one of the implementations that does not allow closed standard descriptors, leading to a failure of test 005.command_li. But a test that makes sure we behave gracefully in the face of closed standard descriptors makes no sense on a platform where we can never have them closed, so add some code to skip the test on "helpful" platforms. Note - HPUX opens any closed standard descriptor as O_WRONLY on /dev/null. This means that attempts to close stdout generally result in silent success, but attempts to close stdin often still result in failure when it is not possible to read from the O_WRONLY stdin. * doc/m4.texi (Command line files): Skip tests on systems where it is impossible to start with stdin/out closed.

* maint: update to latest gnulibEric Blake2013-03-122-0/+5
| | | | | | | | | | | | | | | | | | | | | With the latest gnulib, 'make check' no longer fails to compile for mingw. There are still six gnulib unit test failures, and I'm still investigating if I can come up with some gnulib fixes in the next day or two. But in looking at those failures: FAIL: test-localeconv.exe FAIL: test-lock.exe FAIL: test-mbrtowc1.sh FAIL: test-mbrtowc-w32=1.sh FAIL: test-thread_self.exe FAIL: test-thread_create.exe None of them are show-stoppers to a release of m4 itself, since we still haven't converted m4 to use anything other than the C locale, and since we are single-threaded and don't care about multi-thread locking. * gnulib: Update to latest, for mingw compile fixes.

* build: fix large diversions on mingwEric Blake2013-03-113-0/+23
| | | | | | | | | | | | | | | | | | | | | Gnulib's clean-temp module defaults to using _O_TEMPORARY on mingw, which has the effect of deleting a file the first time it is closed. This resulted in a testsuite failure in 146.diversions, with m4 complaining that it could not create a temporary file for holding a diversion. In reality, m4 was trying to rename the file, but because mingw does not allow renaming an open file, we have to close it first - but closing it first deleted the file. For now, we will just work around the gnulib issue by disabling the use of _O_TEMPORARY. This was probably introduced in commit da5f6db (1.4.13), although my testing environment was painfully slow to confirm this, so I did not call out a 'regression since xyz' in the NEWS entry. * gl/lib/clean-temp.c.diff: New file.

| | | | | | | | | | | | | | | | | | | | Upstream gnulib has added several improvements: - the regex module allows for rational range interprtation (that is, guaranteeing that the regex "[a-z]" evaluates to the same 26 bytes as in ASCII, even when in a non-C locale). Technically, m4 isn't yet using non-C locales, so I don't know if this will make much difference, but it can't hurt to include - various build fixes that I found while smoke-testing on alternative platforms - bump the copyright year to 2013 (I'll do m4 next) * gnulib: Update to latest, for rational range regex, build fixes, copyright update. * m4/gnulib-cache.m4: Regenerate. * NEWS: Document this.
