7b35fd718d python: Fix bindings for virDomainSnapshotGet{Domain,Connect}
https://bugzilla.redhat.com/show_bug.cgi?id=895882

virDomainSnapshot.getDomain() and virDomainSnapshot.getConnect()
wrappers around virDomainSnapshotGet{Domain,Connect} were not supposed
to be ever implemented. The class should contain proper domain() and
connect() accessors that fetch python objects stored internally within
the class. While domain() was already provided, connect() was missing.

This patch adds connect() method to virDomainSnapshot class and
reimplements getDomain() and getConnect() methods as aliases to domain()
and connect() for backward compatibility.

2349d51fbe Make python objects inherit from 'object' base class
As of python >= 2.2, it is recommended that all objects inherit
from the 'object' base class. We already require python >= 2.3
for libvirt for thread macro support, so we should follow this
best practice.

54dd75fd97 Add virTypedParams* APIs
Working with virTypedParameters in clients written in C is ugly and
requires all clients to duplicate the same code. This set of APIs makes
this code for manipulating with virTypedParameters integral part of
libvirt so that all clients may benefit from it.

3d1596b048 Introduce an LXC specific public API & library
This patch introduces support for LXC specific public APIs. In
common with what was done for QEMU, this creates a libvirt_lxc.so
library and libvirt/libvirt-lxc.h header file.

The actual APIs are

  int virDomainLxcOpenNamespace(virDomainPtr domain,
                                int **fdlist,
                                unsigned int flags);

  int virDomainLxcEnterNamespace(virDomainPtr domain,
                                 unsigned int nfdlist,
                                 int *fdlist,
                                 unsigned int *noldfdlist,
                                 int **oldfdlist,
                                 unsigned int flags);

which provide a way to use the setns() system call to move the
calling process into the container's namespace. It is not
practical to write in a generically applicable manner. The
nearest that we could get to such an API would be an API which
allows to pass a command + argv to be executed inside a
container. Even if we had such a generic API, this LXC specific
API is still useful, because it allows the caller to maintain
the current process context, in particular any I/O streams they
have open.

NB the virDomainLxcEnterNamespace() API is special in that it
runs client side, so does not involve the internal driver API.

7ecc1d814a virNodeGetCPUMap: Define public API.
Adding a new API to obtain information about the
host node's present, online and offline CPUs.

int virNodeGetCPUMap(virConnectPtr conn,
                     unsigned char **cpumap,
                     unsigned int *online,
                     unsigned int flags);

The function will return the number of CPUs present on the host
or -1 on failure;
If cpumap is non-NULL virNodeGetCPUMap will allocate an array
containing a bit map representation of the online CPUs. It's
the callers responsibility to deallocate cpumap using free().
If online is non-NULL, the variable pointed to will contain
the number of online host node CPUs.
The variable flags has been added to support future extensions
and must be set to 0.

Extend the driver structure by nodeGetCPUMap entry in support of the
new API virNodeGetCPUMap.
Added implementation of virNodeGetCPUMap to libvirt.c

7ba5defb5a Add support for SUSPEND_DISK event
This patch adds support for SUSPEND_DISK event; both lifecycle and
separated.  The support is added for QEMU, machines are changed to
PMSUSPENDED, but as QEMU sends SHUTDOWN afterwards, the state changes
to shut-off.  This and much more needs to be done in order for libvirt
to work with transient devices, wake-ups etc.  This patch is not
aiming for that functionality.

283f1c4aef python: keep consistent handling of Python integer conversion
libvirt_ulonglongUnwrap requires the integer type of python obj.
But libvirt_longlongUnwrap still could handle python obj of
Pyfloat_type which causes the float value to be rounded up
to an integer.

For example
 >>> dom.setSchedulerParameters({'vcpu_quota': 0.88})
 0
libvirt_longlongUnwrap treats 0.88 as a valid value 0

However
 >>> dom.setSchedulerParameters({'cpu_shares': 1000.22})
libvirt_ulonglongUnwrap will throw out an error
"TypeError: an integer is required"

The patch make this consistent.

37bb0447bb list: add virDomainListAllSnapshots API
There was an inherent race between virDomainSnapshotNum() and
virDomainSnapshotListNames(), where an additional snapshot could
be created in the meantime, or where a snapshot could be deleted
before converting the name back to a virDomainSnapshotPtr.  It
was also an awkward name: the function operates on domains, not
domain snapshots.  virDomainSnapshotListChildrenNames() suffered
from the same inherent race, although its naming was nicer.

This patch makes things nicer by grabbing a snapshot list
atomically, in the format most useful to the user.

bd34cc8c45 python: add API exports for virConnectListAllDomains()
This patch adds export of the new API function
virConnectListAllDomains() to the libvirt-python bindings. The
virConnect object now has method "listAllDomains" that takes only the
flags parameter and returns a python list of virDomain object
corresponding to virDomainPtrs returned by the underlying api.

The implementation is done manually as the generator does not support
wrapping list of virDomainPtrs into virDomain objects.

747f64eeaf lib: Add public api to enable atomic listing of guest
This patch adds a new public api that lists domains. The new approach is
different from those used before. There are key points to this:

1) The list is acquired atomically and contains both active and inactive
domains (guests). This eliminates the need to call two different list
APIs, where the state might change in between the calls.

2) The returned list consists of virDomainPtrs instead of names or ID's
that have to be converted to virDomainPtrs anyways using separate calls
for each one of them. This is more convenient and saves hypervisor calls.

3) The returned list is auto-allocated. This saves a lot of hassle for
the users.

4) Built in support for filtering. The API call supports various
filtering flags that modify the output list according to user needs.

Available filter groups:
    Domain status:
    VIR_CONNECT_LIST_DOMAINS_ACTIVE, VIR_CONNECT_LIST_DOMAINS_INACTIVE

    Domain persistence:
    VIR_CONNECT_LIST_DOMAINS_PERSISTENT,
    VIR_CONNECT_LIST_DOMAINS_TRANSIENT

    Domain state:
    VIR_CONNECT_LIST_DOMAINS_RUNNING, VIR_CONNECT_LIST_DOMAINS_PAUSED,
    VIR_CONNECT_LIST_DOMAINS_SHUTOFF, VIR_CONNECT_LIST_DOMAINS_OTHER

    Existence of managed save image:
    VIR_CONNECT_LIST_DOMAINS_MANAGEDSAVE,
    VIR_CONNECT_LIST_DOMAINS_NO_MANAGEDSAVE

    Auto-start option:
    VIR_CONNECT_LIST_DOMAINS_AUTOSTART,
    VIR_CONNECT_LIST_DOMAINS_NO_AUTOSTART

    Existence of snapshot:
    VIR_CONNECT_LIST_DOMAINS_HAS_SNAPSHOT,
    VIR_CONNECT_LIST_DOMAINS_NO_SNAPSHOT

5) The python binding returns a list of domain objects that is very neat
to work with.

The only problem with this approach is no support from code generators
so both RPC code and python bindings had to be written manually.

*include/libvirt/libvirt.h.in: - add API prototype
                               - clean up whitespace mistakes nearby

4a86c2bb4b python: improve conversion validation
Laszlo Ersek pointed out that in trying to convert a long to an
unsigned int, we used:

long long_val = ...;
if ((unsigned int)long_val == long_val)

According to C99 integer promotion rules, the if statement is
equivalent to:

(unsigned long)(unsigned int)long_val == (unsigned long)long_val

since you get an unsigned comparison if at least one side is
unsigned, using the largest rank of the two sides; but on 32-bit
platforms, where unsigned long and unsigned int are the same size,
this comparison is always true and ends up converting negative
long_val into posigive unsigned int values, rather than rejecting
the negative value as we had originally intended (python longs
are unbounded size, and we don't want to do silent modulo
arithmetic when converting to C code).

Fix this by using direct comparisons, rather than casting.

checks.

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                                                                 \

-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*;' |             \

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.

85f3493f34 domiftune: Add API virDomain{S,G}etInterfaceParameters
The APIs are used to set/get domain's network interface's parameters.
Currently supported parameters are bandwidth settings.

* include/libvirt/libvirt.h.in: new API and parameters definition
* python/generator.py: skip the Python API generation
* src/driver.h: add new entry to the driver structure
* src/libvirt_public.syms: export symbols

ae3315aa4a python: Fix problems of virDomain{Set, Get}BlockIoTune bindings
The parameter 'params' is useless for virDomainGetBlockIoTune API,
and the return value type should be a virTypedParameterPtr but not
integer. And "PyArg_ParseTuple" in functions
libvirt_virDomain{Set,Get}BlockIoTune misses format unit for "format"
argument.

* libvirt-override-api.xml: Remove useless the parameter 'params'
from virDomainGetBlockIoTune API, and change return value type from
integer to virTypedParameterPtr.

* python/libvirt-override.c: Add the missed format units.

78496224f7 python: plug memory leak on libvirt_virConnectOpenAuth
* Detected by valgrind. Leak introduced in commit 5ab109f.

* python/libvirt-override.c: avoid memory leak on libvirt_virConnectOpenAuth.

* How to reproduce?

  % valgrind -v --leak-check=full virt-clone --print-xml
  Note: it can hit the issue although options are incomplete.

* Actual valgrind result:

conn = libvirt.open(None)
dom = conn.lookupByName('test')

mem_contents = dom.memoryPeek(0, 32, libvirt.VIR_MEMORY_VIRTUAL);
sys.stdout.write(mem_contents)

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);
