9943276fd2 Cleanup for a return statement in source files
Return statements with parameter enclosed in parentheses were modified
and parentheses were removed. The whole change was scripted, here is how:

List of files was obtained using this command:
git grep -l -e '\<return\s*([^()]*\(([^()]*)[^()]*\)*)\s*;' |             \
grep -e '\.[ch]$' -e '\.py$'

Found files were modified with this command:
sed -i -e                                                                 \
's_^\(.*\<return\)\s*(\(\([^()]*([^()]*)[^()]*\)*\))\s*\(;.*$\)_\1 \2\4_' \
-e 's_^\(.*\<return\)\s*(\([^()]*\))\s*\(;.*$\)_\1 \2\3_'

Then checked for nonsense.

The whole command looks like this:
git grep -l -e '\<return\s*([^()]*\(([^()]*)[^()]*\)*)\s*;' |             \
grep -e '\.[ch]$' -e '\.py$' | xargs sed -i -e                            \
's_^\(.*\<return\)\s*(\(\([^()]*([^()]*)[^()]*\)*\))\s*\(;.*$\)_\1 \2\4_' \
-e 's_^\(.*\<return\)\s*(\([^()]*\))\s*\(;.*$\)_\1 \2\3_'

487c063381 Add support for the suspend event
This patch introduces a new event type for the QMP event
SUSPEND:

    VIR_DOMAIN_EVENT_ID_PMSUSPEND

The event doesn't take any data, but considering there might
be reason for wakeup in future, the callback definition is:

typedef void
(*virConnectDomainEventSuspendCallback)(virConnectPtr conn,
                                        virDomainPtr dom,
                                        int reason,
                                        void *opaque);

"reason" is unused currently, always passes "0".

a26a1969c3 Add support for event tray moved of removable disks
This patch introduces a new event type for the QMP event
DEVICE_TRAY_MOVED, which occurs when the tray of a removable
disk is moved (i.e opened or closed):

    VIR_DOMAIN_EVENT_ID_TRAY_CHANGE

The event's data includes the device alias and the reason
for tray status' changing, which indicates why the tray
status was changed. Thus the callback definition for the event
is:

enum {
    VIR_DOMAIN_EVENT_TRAY_CHANGE_OPEN = 0,
    VIR_DOMAIN_EVENT_TRAY_CHANGE_CLOSE,

\#ifdef VIR_ENUM_SENTINELS
    VIR_DOMAIN_EVENT_TRAY_CHANGE_LAST
\#endif
} virDomainEventTrayChangeReason;

typedef void
(*virConnectDomainEventTrayChangeCallback)(virConnectPtr conn,
                                           virDomainPtr dom,
                                           const char *devAlias,
                                           int reason,
                                           void *opaque);

2791b8ab9b python: always include config.h first
On RHEL 5.7, I got this compilation failure:

In file included from /usr/include/python2.4/pyport.h:98,
                 from /usr/include/python2.4/Python.h:55,
                 from libvirt.c:3:
../gnulib/lib/time.h:468: error: expected ';', ',' or ')' before '__timer'

Turns out that our '#define restrict __restrict' from config.h wasn't
being picked up.  Gnulib _requires_ that all .c files include <config.h>
first, otherwise the gnulib header overrides tend to misbehave.

Problem introduced by patch c700613b8.

The v4 patch corrects indentation issues.

dom = conn.lookupByName('foo')

print dom.interfaceParameters('vnet0', 0)

params = {'outbound.peak': 10,

c700613b8d python: use libvirt_util to avoid raw free
This patch starts the process of elevating the python binding code
to be on the same level as the rest of libvirt when it comes to
requiring good coding styles.  Statically linking against the
libvirt_util library makes it much easier to write good code,
rather than having to open-code and reinvent things locally.

Done by global search and replace of s/free(/VIR_FREE(/, followed
by hand-inspection of remaining malloc and redundant memset.

* cfg.mk (exclude_file_name_regexp--sc_prohibit_raw_allocation):
Remove python from exemption.
* python/Makefile.am (INCLUDES): Add gnulib and src/util.  Drop
$(top_builddir)/$(subdir), as automake already guarantees that.
(mylibs, myqemulibs): Pull in libvirt_util and gnulib.
(libvirtmod_la_CFLAGS): Catch compiler warnings if configured to
use -Werror.

7b4e5693c1 API: make declaration of _LAST enum values conditional
Although this is a public API break, it only affects users that
were compiling against *_LAST values, and can be trivially
worked around without impacting compilation against older
headers, by the user defining VIR_ENUM_SENTINELS before using
libvirt.h.  It is not an ABI break, since enum values do not
appear as .so entry points.  Meanwhile, it prevents users from
using non-stable enum values without explicitly acknowledging
the risk of doing so.

See this list discussion:
https://www.redhat.com/archives/libvir-list/2012-January/msg00804.html

* include/libvirt/libvirt.h.in: Hide all sentinels behind
LIBVIRT_ENUM_SENTINELS, and add missing sentinels.

baf2ff7e90 startupPolicy: Emit event on disk source dropping
If a disk source gets dropped because it is not accessible,
mgmt application might want to be informed about this. Therefore
we need to emit an event. The event presented in this patch
is however a bit superset of what written above. The reason is simple:
an intention to be easily expanded, e.g. on 'user ejected disk
in guest' events. Therefore, callback gets source string and disk alias
(which should be unique among a domain) and reason (an integer);

f2013c9dd1 snapshot: new virDomainSnapshotListChildrenNames API
The previous API addition allowed traversal up the hierarchy;
this one makes it easier to traverse down the hierarchy.

from the hand-written example of virDomainSnapshotListNames.

b590866bdb freebsd: Fix build problem due to picking up the wrong libvirt.h
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.

f2fb235b1d python: events: Fix C->Python handle callback prototype
If registering our own event loop implementation written in python,
any handles or timeouts callbacks registered by libvirt C code must
be wrapped in a python function. There is some argument trickery that
makes this all work, by wrapping the user passed opaque value in
a tuple, along with the callback function.

Problem is, the current setup requires the user's event loop to know
about this trickery, rather than just treating the opaque value
as truly opaque.

Fix this in a backwards compatible manner, and adjust the example
python event loop to do things the proper way.

f73198df3b python: avoid unlikely sign extension bug
Detected by Coverity.  cpumap was allocated with a value of
(unsigned short)*(int), which is an int computation, and then
promotes to size_t.  On a 64-bit platform, this fails if bit
32 of the product is set (because of sign extension giving
a HUGE value to malloc), even though a naive programmer would
assume that since the first value is unsigned, the product
is also unsigned and at most 4GB would be allocated.

Won't bite in practice (the product should never be that large),
but worth using the right types to begin with, so that we are
now computing (unsigned short)*(size_t).

a6135ec1e6 Introduce a new event emitted when a virtualization failure occurs
This introduces a new domain

  VIR_DOMAIN_EVENT_ID_CONTROL_ERROR

Which uses the existing generic callback

typedef void (*virConnectDomainEventGenericCallback)(virConnectPtr conn,
                                                     virDomainPtr dom,
                                                     void *opaque);

This event is intended to be emitted when there is a failure in
some part of the domain virtualization system. Whether the domain
continues to run/exist after the failure is an implementation
detail specific to the hypervisor.

The idea is that with some types of failure, hypervisors may
prefer to leave the domain running in a "degraded" mode of
operation. For example, if something goes wrong with the QEMU
monitor, it is possible to leave the guest OS running quite
happily. The mgmt app will simply loose the ability todo various
tasks. The mgmt app can then choose how/when to deal with the
failure that occured.
