The reason for this is to fix the automatic rebuild of libvirt-common.h.in.
All *.in files should be automatically rebuilt each time they're modified.
It works well for makefiles and pkgconfig files, since they do have a valid
dependency in the top-level Makefile. However, with libvirt-common.h.in
there is no dependency in the top-level Makefile and there's no need for it
either, so this rule
include/libvirt/libvirt-common.h: $(top_builddir)/config.status \
$(top_srcdir)/include/libvirt/libvirt-common.h.in
cd $(top_builddir) && $(SHELL) ./config.status $@
is never hit and should be moved to include/Makefile, but that's automake's
job. According to GNU automake docs:
"Files created by AC_CONFIG_FILES, be they
Automake Makefiles or not, are all removed by ‘make distclean’. Their inputs
are automatically distributed, unless they are the output of prior
AC_CONFIG_FILES commands. Finally, rebuild rules are generated in the Automake
Makefile existing in the subdirectory of the output file, if there is one, or
in the top-level Makefile otherwise."
Which means that if we want to have the rule for libvirt-common.h automatically
generated by automake, the include/Makefile.am needs to be moved into libvirt/
subdirectory and $SUBDIRS in the top-level Makefile need to be adjusted as
well. This patch moves Makefile.am from include/ to include/libvirt, adjusting
the prefixes accordingly as well as updates the top-level Makefile $SUBDIRS to
properly hint automake to generate all rules at proper places.
Best way to see the changes, use -M with 'git show'.

Using one Makefile per example subdirectory essentially serializes 'make'
calls. Convert to one example/Makefile that builds and distributes
all the subdir files. This reduces example/ rebuild time from about 5.8
seconds to 1.5 seconds on my machine.
One slight difference is that we no longer ship Makefile.am with the
examples in the rpm. This was virtually useless anyways since the Makefile
was very specific to libvirt infrastructure, so wasn't generically
reusable anyways.
Tested with 'make distcheck' and 'make rpm'
Commit e755186c5c added the rename example, but forgot to build some

Creating ACL rules is not exactly easy and existing examples are pretty
simple. This patch adds a somewhat complex example which defines several
roles. Admins can do everything, operators can do basic operations
on any domain and several groups of users who act as operators but only
on a limited set of domains.

You had only one job. That's what you can say about this example
binary. In future, parts of virsh that are usable for this binary

Initial scratch of the admin library. It has its own virAdmConnectPtr
that inherits from virAbstractConnectPtr and thus trivially supports
error reporting.
There's pkg-config file added and spec-file adjusted as well.
Since the library should be "minimalistic" and not depend on any other
library, the list of files is especially crafted for it. Most of them
could've been put to it's own sub-libraries that would be LIBADD'd to
libvirt_util, libvirt_net_rpc and libvirt_setuid_rpc_client to minimize
the number of object files being built, but that's a refactoring that
isn't the orginal aim of this commit.

There's this question on the list that is asked over and over again.
How do I get {cpu, memory, ...} usage in percentage? Or its modified
version: How do I plot nice graphs like virt-manager does?
It would be nice if we have an example to inspire people. And that's
what domtop should do. Yes, it could be written in different ways, but
I've chosen this one as I think it show explicitly what users need to
implement in order to imitate virt-manager's graphing.
Note: The usage is displayed from host perspective. That is, how much
host CPUs the domain is using. But it should be fairly simple to
switch do just guest CPU usage if needed.

The libvirt.so library has far too many library deps to allow
linking against it from setuid programs. Those libraries can
do stuff in __attribute__((constructor) functions which is
not setuid safe.
The virt-login-shell needs to link directly against individual
files that it uses, with all library deps turned off except
for libxml2 and libselinux.
Create a libvirt-setuid-rpc-client.la library which is linked
to by virt-login-shell. A config-post.h file allows this library
to disable all external deps except libselinux and libxml2.

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.

Nehal J. Wani reported on IRC a rather interesting build failure:
In file included from util/virnetdevbridge.c:53:0:
/usr/include/linux/in6.h:30:8: error: redefinition of 'struct in6_addr'
struct in6_addr {
^
I traced it to the fact that he ran 'git pull; make check' across
commit e62e0094. What happened is that the configure changes
result in a new variable that was set to be defined on his system,
but config.h was not regenerated to contain the value of that
variable. Running 'make' instead of 'make check' cleaned up the
problem. A bit more investigation, and I see that in Makefile.am,
automake sticks rules that rebuild config.h as part of 'make all',
and that we also had a dependency 'check-local: all'; BUT the
rule for check-local is run only at the point when the top-level
directory is visited. Automake documents that SUBDIRS should
contain an explicit '.' at the point the top-level should be
visited (defaulting to last, if it doesn't appear). Sure enough,
with this patch, 'make check' now does the top-level 'all' rules,
which regenerates 'config.h' BEFORE compiling any code that might
depend on changed content of that file.

Using s/#authorslist#/$$out/ makes perl eat @domain part of all email
addresses from $out since it tries to interpret them as array variables.
I'm not sure if we can escape those in s/// but I know we can use print:
s/#authorslist#// and print '$$out'
to tell perl not to even look inside $out.
This patch also fixes gen-AUTHORS so that it works in VPATH.
I noticed that on Fedora 18, xlstproc decides to regenerate
HACKING with additional whitespace. I haven't figured out why
that is happening (although fixing it would probably be a task
for xlstproc), but in the process of investigating, I noticed
that 'make HACKING' was completely silent, for no good reason.
* Makefile.am (gen-ChangeLog, gen-AUTHORS, NEWS)
($(top_srcdir)/HACKING): Mention which files we are generating.
AUTHORS.in tracks the maintainers, as well as some folks who were
previously in AUTHORS but don't have a git commit with proper
attribution.
Generated output is sorted alphabetically and lacks pretty spacing, so
tweak AUTHORS.in to follow the same format.
Additionally, drop the syntax-check rule that previously validated
AUTHORS against git log.
With this script you can run libvirt programs without needing to
install them first. You just have to do for example:
./run ./tools/virsh [args ...]
If you are already in the tools/ subdirectory, then the following
command will also work:
../run ./virsh [...]
You can also run the C programs under valgrind like this:
./run valgrind [valgrind opts...] ./program
or under gdb:
./run gdb --args ./program
This also works with sudo (eg. if you need root access for libvirt):
sudo ./run ./tools/virsh list --all
Derived from libguestfs and simplified. The ./run script in
libguestfs is much more sophisticated:

* configure.ac: Declare copyright.

The rule of thumb is that any file generated by config.status
is a) reproducible by any user, b) dependent on configure options.

Using 'int ret = strcmp(a, b)' in a qsort function is a valid use of

already has a tighter bound for strcmp, so we can copy that regex and
just check for strncmp, which results in fewer false positives that
require exceptions.

Adds initial support for dtrace static probes in libvirtd
daemon, assuming use of systemtap dtrace compat shim on
Linux. The probes are inserted for network client connect,
disconnect, TLS handshake states and authentication protocol
states.
This can be tested by running the xample program and then
attempting to connect with any libvirt client (virsh,
virt-manager, etc).
# stap examples/systemtap/client.stp
Client fd=44 connected readonly=0
Client fd=44 auth polkit deny pid:24997,uid:500
Client fd=44 disconnected
Client fd=46 connected readonly=1
Client fd=46 auth sasl allow test
Client fd=46 disconnected
The libvirtd.stp file should also really not be required,
since it is duplicated info that is already available in
the main probes.d definition file. A script to autogenerate
the .stp file is needed, either in libvirtd tree, or better
as part of systemtap itself.
