prevent aclocal from preferring .m4 files under m4/ over the version
provided by gnulib, by using only one directory.
I have noticed this after './configure --help' gave me two different
versions of "--enable-threads". This was caused by aclocal that
preferred the version of lock.m4 provided by autopoint instead of
using the newer version distributed with gnulib.
Having two different directories made sense back when we checked
gnulib files into libvirt.git, but that was ages ago.

I noticed that in a fresh checkout, autogen.sh generated the
following output, but continued on with execution:
autoreconf: running: automake --add-missing --copy --force-missing
gnulib/tests/Makefile.am:28: TESTS was already defined in condition TRUE, which includes condition WITH_EXPENSIVE_TESTS ...
gnulib/tests/gnulib.mk:28: ... `TESTS' previously defined here
gnulib/tests/Makefile.am:19: `gnulib/tests/gnulib.mk' included from here
and after the run, line 28 of gnulib.mk lists GNULIB_TESTS, not TESTS.
After more investigation, I found that it is because gnulib bootstrap
provides two hooks, one before automake, and the other after; we used
the one that ran after, and were then rerunning automake ourselves;
and the warning was from the first run. But a manual second run is
pointless if we use the right hook in the first place.
The wrong function name has been latent since commit 38c9440, and we
tried to work around it in commit 6cbab7c, but it took commit 70363ea
to finally change output enough for me to realize the root cause.

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.

Since neither getpwuid_r() nor initgroups() are safe to call in
between fork and exec (they obtain a mutex, but if some other
thread in the parent also held the mutex at the time of the fork,
the child will deadlock), we have to split out the functionality
that is unsafe. At least glibc's initgroups() uses getgrouplist
under the hood, so the ideal split is to expose getgrouplist for
use before a fork. Gnulib already gives us a nice wrapper via
mgetgroups; we wrap it once more to look up by uid instead of name.

Commit 8fe455fd36 tried to work around
a regression introduced in upstream gnulib that requires gettext 0.18
or newer on all projects using bootstrap, by making libvirt require
gettext 0.18. But this fails on RHEL 6.2, which still ships gettext
0.17. Revert that change, and instead, import the latest round of
gnulib updates that fix that problem properly.
If you have already built in the window where libvirt required 0.18,
be aware that incremental updates may run into problems: this is
because 'autopoint --force' will not downgrade m4/po.m4 back to an
older version, but it must be downgraded back to 0.17 levels to work
with this patch. You may either manually remove that file then rerun
bootstrap, or it may prove easier to just clean up all non-git files
to start from a clean slate.

Commit c9cd419cab added copying of the

Recent discussions have illustrated the potential for DOS attacks
with the hash table implementations used by most languages and
libraries.
https://lwn.net/Articles/474912/
libvirt has an internal hash table impl, and uses hash tables for
a variety of purposes. The hash key generation code is pretty
simple and thus not strongly collision resistant.
This patch replaces the current libvirt hash key generator with
the (public domain) Murmurhash3 code. In addition every hash
table now gets a random seed value which is used to perturb the
hashing code. This should make it impossible to mount any
practical attack against libvirt hashing code.
* bootstrap.conf: Import bitrotate module
* src/Makefile.am: Add virhashcode.[ch]
* src/util/util.c: Make virRandom() return a fixed 32 bit
integer value.

Jiri Denemark reported an instance of bootstrapping libvirt
failing when run inside a sandbox, traced to rpm trying to

is not installed.
* bootstrap.conf (buildreq): Avoid rpm call if python-config
exists. Also, require patch, in case we have gnulib-local diffs.
We want our tarballs to be complete - this means that any
generated file that gets shipped as part of the tarball so that
ordinary users don't have to rebuild it must be something
that the maintainer can generate. There have been various
reports of random build failures when using libvirt.git
instead of a tarball, and often it is due to missing a
maintainer-specific tool to produce one of these generated
files. This patch raises the bar for what you must have
installed to build libvirt.git, but does not impact what
you can get away with for building tarballs.
Note: It still remains possible to do a successful 'make dist'
without these tools, when starting from a release tarball.
* bootstrap.conf (buildreq): Add tools that maintainers need for a
successful 'make dist' from a fresh git checkout.
Commit f7bd00c12 pulled in a gnulib module that fails to compile
on mingw. While it would be nice to pull in a newer version of
.gnulib that fixes this, it is difficult to backport any .gnulib
update to older releases. So, it makes sense to take advantage
of gnulib-tool's ability to support local diffs, where we can
apply specific diffs in our use of gnulib without waiting for
upstream gnulib to pick up those changes, as well as avoiding
a wholesale .gnulib update. The existence of local diffs will
also make it easier to backport fixes against a tarball (as long
as a tarball and libvirt.git share the same .gnulib commit, then
the tarball can be patched by applying the same local diffs as
a post-release libvirt.git commit, without having to rerun an
entire gnulib-tool bootstrap).
This patch introduces the framework for supporting local diffs,
without actually introducing any.
* bootstrap.conf (local_gl_dir): New variable.
* autogen.sh (bootstrap_hash): Hash any local diffs, to force a
re-bootstrap if just diffs change.

MacOS lacks ptsname_r, and gnulib doesn't (yet) provide it.
But we can avoid it altogether, by using gnulib openpty()
instead. Note that we do _not_ want the pt_chown module;
gnulib uses it only to implement a replacement openpty() if
the system lacks both openpty() and granpt(), but all
systems that we currently port to either have at least one of
openpty() and/or grantpt(), or lack ptys altogether. That is,
we aren't porting to any system that requires us to deal with
the hassle of installing a setuid pt_chown helper just to use
gnulib's ability to provide openpty() on obscure platforms.
* .gnulib: Update to latest, for openpty fixes
* bootstrap.conf (gnulib_modules): Add openpty, ttyname_r.

Commit 1726a73 hacked around MacOS' lack of fdatasync, since
gnulib did not have it at the time. But now that we use newer
gnulib, we can avoid the hack.
* bootstrap.conf (gnulib_modules): Add fdatasync.
* configure.ac (AC_CHECK_FUNCS_ONCE): Drop our own check.
Mingw lacks fsync, but gnulib provides that. Meanwhile, gnulib does
not (yet) provide fdatasync, so this is a quick hack to fake that
function on MacOS X; we can revert this configure change once gnulib
gives us a real module.
We have been implicitly relying on gnulib's largefile module being
pulled in by other modules, but it's better to make that explicit.
* bootstrap.conf (gnulib_modules): Add fsync. Make largefile use
explicit.
* configure.ac (AC_CHECK_FUNCS_ONCE): Check for fdatasync, and
fake it with fsync when not present.
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.

Gnulib documents that mingw vsnprintf is broken (it returns -1
on out-of-space, instead of the count of what would have been
printed); but while we were using the snprintf wrapper, we had
not yet been using the vsnprintf wrapper.
Meanwhile, mingw (but not mingw64) has a replacement snprintf
that fixes return values, but still lacks %1$s support; so in
that case, gnulib didn't replace snprintf, but libintl then
went ahead and installed a version that supported %1$s but not
return values. Gnulib has since been fixed to guarantee that
the snprintf module will always guarantee the constraints needed
by libintl.
Also, we want to guarantee that strdup sets errno on failure.

and this solution to work around it.
* bootstrap.conf (bootstrap_epilogue): Ensure that no stray
../../.. components remain in gnulib/tests/Makefile.in.
Reported by Serge Hallyn.
* .gnulib: Update to latest, for sigpipe and sigaction modules.
* bootstrap.conf (gnulib_modules): Add siaction, sigpipe, strerror_r.
* tools/virsh.c (vshSetupSignals) [!SIGPIPE]: Delete, now that
gnulib guarantees it.
(SA_SIGINFO): Define for mingw fallback.
* src/util/virterror.c (virStrerror): Simplify, now that gnulib
guarantees the POSIX interface.
* configure.ac (AC_CHECK_FUNCS_ONCE): Drop redundant check.
(AM_PROG_CC_STDC): Move earlier, to keep autoconf happy.
* .gnulib: Update to latest.
* bootstrap.conf (gnulib_modules): Import pipe-posix and waitpid
for mingw.
* src/remote/remote_driver.c (pipe) [WIN32]: Drop dead macro.
* daemon/event.c (pipe) [WIN32]: Drop dead function.
* .gnulib: Update to latest, for bootstrap fixes.
* bootstrap: Synchronize with upstream.
* bootstrap.conf: Add pkg-config pre-requisite.
* autogen.sh: Tweak wording message.
Reported by Justin Clift, and with feedback from Bruno Haible.
Partial reversion of commit 76d87a59, now that bootstrap is smarter.
* .gnulib: Update to latest, for poll and bootstrap fixes.
* bootstrap: Resync from gnulib.
* autogen.sh: Drop redundant tool checks; bootstrap does them
better, by honoring environment variables.
* examples/domain-events/events-c/Makefile.am (INCLUDES)
(event_test_LDADD): Use gnulib library during build.
* bootstrap.conf (gnulib_tool_option_extras): Revert --libtool
addition, now that updated bootstrap does it for us.
Reported by Justin Clift.
snprintf is currently implicitly picked up by getaddrinfo, but we
might as well make it explicit so that mingw doesn't break if
getaddrinfo changes to drop the dependency.
func doesn't matter for gcc compilation, but may help other compilers
cope with our use of __func__.
* bootstrap.conf (gnulib_modules): Add snprintf and func.
With the previous storage pool UUID source not all storage pools
had a proper UUID, especially GSX storage pools. The mount path
is unique per host and cannot change during the lifetime of the
datastore. Therefore, it's MD5 sum can be used as UUID.
Use gnulib's crypto/md5 module to generate the MD5 sum.
On Fedora 13 with sufficient mingw32-* packages installed, running
./autobuild.sh failed to cross-compile to mingw because
mingw32-pthreads installed a broken <pthread.h>. With that
issue fixed, the build still failed due to use of O_SYNC.
Meanwhile, recent .spec.in changes got out of sync.
* bootstrap.conf (gnulib_modules): Add fcntl-h, for O_SYNC.
* .gnulib: Update to latest, to work around buggy pthreads-win32
library.
* bootstrap: Import latest from gnulib.
* mingw32-libvirt.spec.in: Distribute new file.
Gnulib can guarantee that pthread.h exists, but for now, it is a dummy
header with no support for most pthread_* functions. Modify our
use of pthread to use function checks, rather than header checks,
to determine how much pthread support is present.
* bootstrap.conf (gnulib_modules): Add pthread.
* configure.ac: Drop all pthread.h checks. Optimize function
checks. Add check for pthread functions.
* src/Makefile.am (libvirt_lxc_LDADD): Ensure proper link.
* src/remote/remote_driver.c (remoteIOEventLoop): Depend on
pthread_sigmask, now that gnulib guarantees pthread.h.
* src/util/util.c (virFork): Likewise.
* src/util/threads.c (threads-pthread.c): Depend on
pthread_mutexattr_init, as a witness of full pthread support.
* src/util/threads.h (threads-pthread.h): Likewise.
strtok_r will be used in the ESX driver to replace scanf-based code.
MinGW lacks strtok_r, so we need gnulib to provide it, but until now
strtok_r was licensed LGPL3.
Fix invalid code generating in esx_vi_generator.py regarding deep copy
types that contain enum properties.
Add strptime and timegm to bootstrap.conf. Both are used to convert a
xsd:dateTime to calendar time.
Add a testcase of the xsd:dateTime conversion.
rsync is used to download .po files, but SKIP_PO=true is set and
downloading .po files is skipped.
This also fixes a problem with MinGW builds, because rsync is not
available for MinGW.
The current code for "nodeinfo" is pretty naive
about socket and thread information. To determine the
sockets, it just takes the number of cpus and divides
by the number of cores. For the thread count, it always
sets it to 1. With more recent Intel machines, however,
hyperthreading is again an option, meaning that these
heuristics no longer work and give bogus numbers. This
patch goes through /sys to get the additional
information so we properly report it.
Note that I had to edit the tests not to report on
socket and thread counts, since these are determined
dynamically now.
v2: As pointed out by Eric Blake, gnulib provides
count-one-bits (which is LGPLv2+). Use it instead
of a hand-coded popcnt.

Requiring git 1.6.4, just for the optional GNULIB_SRCDIR support,
was too harsh. Resynchronize from gnulib.
* .gnulib: Import from latest gnulib.
* bootstrap: Re-synchronize from .gnulib/build-aux.
* bootstrap.conf: Drop git to 1.5.5.
* README-hacking: Document use of GNULIB_SRCDIR.
Copy the latest gnulib bootstrap, which runs autoreconf and
generates po/Makevars for us. Other improvements include some
improved prerequisite tool checking.
This also fixes a bug in the .pot files, regarding the copyright holder.
* bootstrap: Update to version in .gnulib/build-aux.
* bootstrap.conf (MSGID_BUGS_ADDRESS, COPYRIGHT_HOLDER, SKIP_PO)
(gnulib_mk, ACLOCAL, bootstrap_epilogue): Provide overrides.
* autogen.sh (autoreconf): Avoid redundant autoreconf if bootstrap
was run.
* po/Makevars: Delete, now that bootstrap creates it.
* po/.gitignore: Update.
Borrow ideas from gnulib/build-aux/bootstrap, in order to factor the
specifics of libvirt into bootstrap.conf, while allowing future
upgrades of bootstrap to happen with less effort.
* bootstrap (gnulib_tool): Update invocation to be closer to
gnulib's version. Move libvirt specifics...
* bootstrap.conf: ...into new file.
