Commit f2013c9dd1ce468b8620ee35c232a93ef7026fb0 added implementation of
virDomainSnapshotListChildrenNames override export, but registration of
the newly exported function was not added.
*python/libvirt-override.c: - register export of function
This patch adds binding for virNodeGetMemoryStats method of libvirtd.
Return value is represented as a python dictionary mapping field
names to values.
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);
The previous API addition allowed traversal up the hierarchy;
this one makes it easier to traverse down the hierarchy.
In the python bindings, virDomainSnapshotNumChildren can be
generated, but virDomainSnapshotListChildrenNames had to copy
from the hand-written example of virDomainSnapshotListNames.
* include/libvirt/libvirt.h.in (virDomainSnapshotNumChildren)
(virDomainSnapshotListChildrenNames): New prototypes.
(VIR_DOMAIN_SNAPSHOT_LIST_DESCENDANTS): New flag alias.
* src/libvirt.c (virDomainSnapshotNumChildren)
(virDomainSnapshotListChildrenNames): New functions.
* src/libvirt_public.syms: Export them.
* src/driver.h (virDrvDomainSnapshotNumChildren)
(virDrvDomainSnapshotListChildrenNames): New callbacks.
* python/generator.py (skip_impl, nameFixup): Update lists.
* python/libvirt-override-api.xml: Likewise.
* python/libvirt-override.c
(libvirt_virDomainSnapshotListChildrenNames): New wrapper function.
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.

I went with the shorter license notice used by src/libvirt.c,
rather than spelling out the full LGPLv2+ clause into each of
these files.
* configure.ac: Declare copyright.
* all Makefile.am: Likewise.
This patch adds the Python bindings for virDomainGetVcpuPinInfo API.
* python/generator.py: add it to generator skip list
* python/libvirt-override-api.xml: provide an override description
* python/libvirt-override.c: provide an override binding implementation
This patch adds the Python bindings for virDomainPinVcpuFlags API.
* python/generator.py: add it to the generator skip list
* python/libvirt-override-api.xml: provide override description
* python/libvirt-override.c: provide override bindings implementation
This patch adds the Python bindings for
virDomainGetSchedulerParametersFlags API.
* python/libvirt-override-api.xml: provide and override description
* python/libvirt-override.c: implement the bindings
When an operation started by virDomainBlockPull completes (either with
success or with failure), raise an event to indicate the final status.
This API allow users to avoid polling on virDomainGetBlockJobInfo if
they would prefer to use an event mechanism.
* daemon/remote.c: Dispatch events to client
* include/libvirt/libvirt.h.in: Define event ID and callback signature
* src/conf/domain_event.c, src/conf/domain_event.h,
src/libvirt_private.syms: Extend API to handle the new event
* src/qemu/qemu_driver.c: Connect to the QEMU monitor event
for block_stream completion and emit a libvirt block pull event
* src/remote/remote_driver.c: Receive and dispatch events to application
* src/remote/remote_protocol.x: Wire protocol definition for the event
* src/remote_protocol-structs: structure definitions for protocol verification
* src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h,
src/qemu/qemu_monitor_json.c: Watch for BLOCK_STREAM_COMPLETED event
from QEMU monitor
virDomainGetBlockJobInfo requires manual override since it returns a
custom type.
* python/generator.py: reenable bindings for this entry point
* python/libvirt-override-api.xml python/libvirt-override.c:
manual overrides
Set up the types for the block pull functions and insert them into the
virDriver structure definition. Symbols are exported in this patch to
prevent
documentation compile failures.
* include/libvirt/libvirt.h.in: new API
* src/driver.h: add the new entry to the driver structure
* python/generator.py: fix compiler errors, the actual python bindings
* are
implemented later
* src/libvirt_public.syms: export symbols
* docs/apibuild.py: Extend 'unsigned long' parameter exception to this
* API
Commit 8665f85523f0451c changed generated.stamp to $(GENERATE).stamp,
but missed one instance in the CLEANFILES list. This can break the
build in case the generated code is deleted but the .stamp file stays
around and therefore the code isn't regenerated.
The current API build scripts will continue and exit with a zero
status even if they find problems. This has been the cause of many
build problems, or hidden build errors, in the past. Change the
scripts so they always exit with a non-zero status for any problems
they do not understand. Also turn off all debug output by default
so they respect $(AM_V_GEN)
* docs/Makefile.am: Use $(AM_V_GEN) for API/HTML scripts
* docs/apibuild.py, python/generator.py: Exit with non-zero status
if problems are found. Also be silent, not outputting any debug
messages.
* src/Makefile.am: Use $(AM_V_GEN) for ESX generator
* python/Makefile.am: Tweak rule
According to the automake manual, CPPFLAGS (aka INCLUDES, as spelled
in automake 1.9.6) should only include -I, -D, and -U directives; more
generic directives like -Wall belong in CFLAGS since they affect more
phases of the build process. Therefore, we should be sticking CFLAGS
additions into a CFLAGS container, not a CPPFLAGS container.
* src/Makefile.am (libvirt_driver_vmware_la_CFLAGS): Use AM_CFLAGS.
(INCLUDES): Move CFLAGS items...
(AM_CFLAGS): ...to their proper location.
* python/Makefile.am (INCLUDES, AM_CFLAGS): Likewise.
* tests/Makefile.am (INCLUDES, AM_CFLAGS): Likewise.
(commandtest_CFLAGS, commandhelper_CFLAGS)
(virnetmessagetest_CFLAGS, virnetsockettest_CFLAGS): Use AM_CFLAGS.
Commit cd48c3f4e95597 added a Py_ssize_t typedef for Python < 2.7.
But Py_ssize_t was added in Python 2.5. This makes the build fail
for Python 2.6.
Adjust the check to match Python < 2.5 to fix this.
I'm not sure when Py_ssize_t was introduced; but Fedora 14 Python 2.7
has it, while RHEL 5 Python 2.4 lacks it. It should be easy enough
to adjust if someone runs into problems.
* python/typewrappers.h (Py_ssize_t): Define for older python.
On RHEL 5, I got:
/usr/bin/python ./generator.py /usr/bin/python
File "./generator.py", line 427
"virStreamFree", # Needed in custom virStream __del__, but free shouldn't
^
SyntaxError: invalid syntax
* python/generator.py (function_skip_python_impl): Use same syntax
as other skip lists.
Turns out I was right in removing this the first time :) This is
needed in our custom __del__ function, but the C code wasn't
being generated. Add new infrastructure to do what we want
These functions aren't intended to be called directly by users, so mark
them as private.
While we're at it, remove unneeded exception handling, and break some
long lines.
