log2() is heavy when ffs() can do the same thing. But ffs()
requires gnulib support for mingw.
This patch solves this linker error on Fedora 14.
/usr/bin/ld: libvirt_lxc-domain_conf.o: undefined reference to symbol 'log2@@GLIBC_2.2.5'
/usr/bin/ld: note: 'log2@@GLIBC_2.2.5' is defined in DSO /lib64/libm.so.6 so try adding it to the linker command line
/lib64/libm.so.6: could not read symbols: Invalid operation
collect2: ld returned 1 exit status
* .gnulib: Update to latest, for ffs.
* bootstrap.conf (gnulib_modules): Import ffs.
* src/conf/domain_conf.c (virDomainDefParseXML): Use ffs instead
of log2.

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.
* .gnulib: Update to latest, for vsnprintf fix.
* bootstrap.conf (gnulib_modules): Add vsnprintf, strdup-posix.

./autobuild.sh died on several messages resembling:
../../src/rpc/virnetsocket.c: In function 'virNetSocketNewListenTCP':
../../src/rpc/virnetsocket.c:231:9: error: implicit declaration of function 'bind_used_without_requesting_gnulib_module_bind' [-Wimplicit-function-declaration]
../../src/rpc/virnetsocket.c:231:9: error: nested extern declaration of 'bind_used_without_requesting_gnulib_module_bind' [-Wnested-externs]
Basically, gnulib socket fds are not safe to pass to mingw socket
functions unless we pull in those gnulib modules.
* bootstrap.conf (gnulib_modules): Add modules to handle socket
functions on mingw.
Done as a separate commit to make backporting the next patch easier.
We are already using "intprops.h", but this makes it explicit.
* .gnulib: Update, for syntax-check fix.
* bootstrap.conf (gnulib_modules): Make intprops use explicit.
* src/locking/domain_lock.c (includes): Drop unused header.
* src/nwfilter/nwfilter_learnipaddr.c (includes): Use "", not <>,
for gnulib.
Now that RHEL 5.6 ships with gettext 0.17, we can get out of the
stone age and use the newer gettext capabilities and improved
macros for certain configure tests.
* configure.ac (AM_GNU_GETTEXT_VERSION): Bump to 0.17.
(MKINSTALLDIRS): Delete hack that is no longer needed.
* bootstrap.conf (buildreq): Check for minimum gettext version.
Based on a report by Wen Congyang.
The libvirtd daemon uses fnmatch. Although we don't yet build
it on Win32, we should use gnulib's fnmatch module to ensure
portability to all platforms.
* bootstrap.conf: Add fnmatch
Always generate the rpc files, and require rpcgen during bootstrap.
* daemon/Makefile.am: Removed generated files with
maintainer-clean target
* src/Makefile.am: Removed generated files with
maintainer-clean target. Always run 'rpcgen' if
generated files are missing
Match the fact that we have virAsprintf and virVasprintf.
* src/util/buf.h (virBufferVasprintf): New prototype.
* src/util/buf.c (virBufferAsprintf): Move guts...
(virBufferVasprintf): ...to new function.
* src/libvirt_private.syms (buf.h): Export it.
* bootstrap.conf (gnulib_modules): Add stdarg, for va_copy.
This patch enables the migration of Qemu VMs between hosts of different endianess. I tested this by migrating a i686 VM between a x86 and ppc64 host.
I am converting the 'int's in the VM's state header to uint32_t assuming this doesn't break compatibility with existing deployments other than Linux.
* .gnulib: Update to latest, for pipe2.
* bootstrap.conf (gnulib_modules): Add pipe2.
* src/util/event_poll.c (virEventPollInit): Use it, to avoid
problematic virSetCloseExec on mingw.
Remove custom code for checking compiler warnings, using
gl_WARN_ADD instead. Don't list all flags ourselves, use
gnulib's gl_MANYWARN_ALL_GCC to get all possible GCC flags,
then turn off the ones we don't want yet.
* acinclude.m4: Rewrite to use gl_WARN_ADD and gl_MANYWARN_ALL_GCC
* bootstrap.conf: Add warnings & manywarnings
* configure.ac: Switch to gl_WARN_ADD
* m4/compiler-flags.m4: Obsoleted by gl_WARN_ADD
strcase{cmp/str} have the drawback of being sensitive to the global
locale; this is unacceptable in a library setting. Prefer a
hard-coded C locale alternative for all but virsh, which is user
facing and where the global locale isn't changing externally.
* .gnulib: Update to latest, for c-strcasestr change.
* bootstrap.conf (gnulib_modules): Drop strcasestr, add c-strcase
and c-strcasestr.
* cfg.mk (sc_avoid_strcase): New rule.
(exclude_file_name_regexp--sc_avoid_strcase): New exception.
* src/internal.h (STRCASEEQ, STRCASENEQ, STRCASEEQLEN)
(STRCASENEQLEN): Adjust offenders.
* src/qemu/qemu_monitor_text.c (qemuMonitorTextEjectMedia):
Likewise.
* tools/virsh.c (namesorter): Document exception.
Not every day you see a patch that nukes 27 files!
* .gnulib: Update to latest, for maint.mk improvements
* bootstrap: Resync to gnulib.
* bootstrap.conf (ACLOCAL): Swap the secondary aclocal include
directory, now that bootstrap picks up gnulib/m4 instead of m4.
* Makefile.am (syntax_check_exceptions, EXTRA_DIST): No longer
worry about nuked files.
* cfg.mk (sc_x_sc_dist_check): Delete dead rule.
(VC_LIST_ALWAYS_EXCLUDE_REGEX): Add HACKING.
(exclude_file_name_regexp--sc_*): Inline and simplify contents...
* .x-sc_*: ...from here, then delete the files.
A diff of 'make dist' from in-tree vs. a VPATH build showed
that we were missing docs/api_extension/*.patch files, but
shipping other files that we didn't need.
* bootstrap.conf (gnulib_extra_files): Don't distribute files we
don't care about.
* docs/Makefile.am (patches): Perform wildcard correctly.
Running 'make check' can sometimes fail in the gnulib/tests
subdirectory, when doing an incremental build, because
./bootstrap generates a Makefile.am that tries to refer to
../../.. instead of ../.., and gets lost.
This may be an upstream gnulib bug, where a more elegant
solution will present itself in the future:
http://thread.gmane.org/gmane.comp.lib.gnulib.bugs/24898
But in the meantime, I was able to reproduce both the issue,
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.
