The gnulib testsuite is relatively stable - the only times it is
likely to have a test change from pass to fail is on a gnulib
submodule update or a major system change (such as moving from
Fedora 18 to 19, or other large change to libc). While it is an
important test for end users on arbitrary machines (to make sure
that the portability glue works for their machine), it mostly
wastes time for development testing (as most developers aren't
making any of the major changes that would cause gnulib tests
to alter behavior). Thus, it pays to make the tests optional
at configure time, defaulting to off for development, on for
tarballs, with autobuilders requesting it to be on. It also
helps to allow a make-time override, via VIR_TEST_EXPENSIVE=[01]
(much the way automake sets up V=[01] for overriding the configure
time default of how verbose to be).
Automake has some pretty hard-coded magic with regards to the
TESTS variable; I had quite a job figuring out how to keep
'make distcheck' passing regardless of the configure option
setting in use, while still disabling the tests at runtime
when I did not configure them on and did not use the override
variable. Thankfully, we require GNU make, which lets me
hide some information from Automake's magic handling of TESTS.
* bootstrap.conf (bootstrap_epilogue): Munge gnulib test variable.
* configure.ac (--enable-expensive-tests): Add new enable switch.
(VIR_TEST_EXPENSIVE_DEFAULT, WITH_EXPENSIVE_TESTS): Set new
witnesses.
* gnulib/tests/Makefile.am (TESTS): Make tests conditional on
configure settings and the VIR_TEST_EXPENSIVE variable.
* tests/Makefile.am (TESTS_ENVIRONMENT): Expose VIR_TEST_EXPENSIVE
to all tests.
* autobuild.sh: Enable all tests during autobuilds.
* libvirt.spec.in (%configure): Likewise.
* mingw-libvirt.spec.in (%mingw_configure): Likewise.
* docs/hacking.html.in: Document the option.
* HACKING: Regenerate.

Gettext annoyingly modifies CPPFLAGS in-place, putting
-I/usr/local/include into the search patch if libintl headers
must be used from that location. But since we must support
automake 1.9.6 which lacks AM_CPPFLAGS, and since CPPFLAGS is used
prior to INCLUDES, this means that the build picks up the _old_
installed libvirt.h in priority to the in-tree version, leading
to all sorts of weird build failures on FreeBSD.
Fix this by teaching configure to undo gettext's actions, but
to keep any changes required by gettext at the end of INCLUDES
after all in-tree locations are used first. Also requires
adding a wrapper Makefile.am and making gnulib-tool create
just gnulib.mk files during the bootstrap process.

This makes it so we record (via a git submodule)
a snapshot of whatever version of gnulib we're using,
and none of gnulib sources are in the libvirt repository.
The result is that we have as much reproducibility as when
we version-controlled imported copies of the gnulib sources,
but without the hassle of the manual process we used when
syncing with upstream.
Note that when you clone libvirt, you get only the libvirt
repository, but when you first run ./bootstrap, it clones
gnulib (at the SHA1 recorded via the submodule), creating
the .gnulib/ hierarchy. Then, the bootstrap script runs
gnulib-tool to populate gnulib/ with the files that make
up the selected modules.
Put the following in your ~/.gitconfig file.
[alias]
syncsub = submodule foreach git pull origin master
The update procedure is simple:
git syncsub
...build & test...
git commit -m 'gnulib: sync submodule to latest' .gnulib
* .gitmodules: New file.
* .gnulib: Initialize.
* bootstrap: Set up to use the new submodule.
Stop using --no-vc-files.
Don't remove .gitignore files.
Don't use or create .cvsignore.
Diagnose an invalid --gnulib-srcdir=DIR argument.
* build-aux/vc-list-files: Delete file, now pulled from gnulib.
* build-aux/useless-if-before-free: Likewise.
* po/POTFILES.in: Remove gnulib/lib/gai_strerror.c, since
it no longer contains translatable strings.
* gnulib/*: Remove gnulib/ hierarchy.
* bootstrap: Invoke gnulib-tool with its --no-vc-files
option, since we version-control the files it imports.
This tells it not to mark imported files as cvs-ignored.
(modules): Add ioctl.
* gnulib/lib/ioctl.c: New file.
* gnulib/lib/sys_ioctl.in.h: New file.
* gnulib/tests/sys_ioctl.in.h: Removed.
* gnulib/tests/ioctl.c: Removed.
* gnulib/lib/Makefile.am: Update.
* gnulib/m4/gnulib-cache.m4: Likewise.
* gnulib/m4/gnulib-comp.m4: Likewise.
* gnulib/tests/Makefile.am: Likewise.
* gnulib/lib/.cvsignore: Ignore sys_ioctl.h.
* gnulib/lib/.gitignore: Regenerate.
* bootstrap (modules): Add mkstemp.
The remainder of these changes are the result of running
./bootstrap, adding new files, and committing the result.
* gnulib/lib/gettimeofday.c: New file.
* gnulib/lib/mkstemp.c: New file.
* gnulib/lib/tempname.c: New file.
* gnulib/lib/tempname.h: New file.

(EXTRA_DIST): Add test-lib.sh.
* tests/test-lib.sh: Testing framework, from coreutils.
* tests/vcpupin: New file.
* build-aux/mktempd: New file, from gnulib.
