Set up the types for the block pull functions and insert them into the

* src/libvirt_public.syms: export symbols

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
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
Since we virEventRegisterDefaultImpl is now a public API, callers need
a way to invoke the default registered Handle and Timeout functions. We
already have general functions for these internally, so promote
them to the public API.
v2:
Actually add APIs to libvirt.h
Pure python implementation. The handler callbacks have been altered
a bit compared to the C API: RecvAll doesn't pass length of the data read
since that can be trivially obtained from python string objects, and SendAll
requires the handler to return the string data to send rather than
store the data in a string pointer.
The return values for the python version are different that the C version
of virStreamSend: on success we return a string, an error raises an exception,
and if the stream would block we return int(-2). We need to do this
since strings aren't passed by reference in python.
virDomainBlockPullAll and virDomainBlockPullAbort are handled automatically.
virDomainBlockPull and virDomainBlockPullInfo require manual overrides since
they return a custom type.

Add public virDomainSendKey() and enum libvirt_keycode_set
for the @codeset.

This patch deprecates following enums:
VIR_DOMAIN_MEM_CURRENT
VIR_DOMAIN_MEM_LIVE
VIR_DOMAIN_MEM_CONFIG
VIR_DOMAIN_VCPU_LIVE
VIR_DOMAIN_VCPU_CONFIG
VIR_DOMAIN_DEVICE_MODIFY_CURRENT
VIR_DOMAIN_DEVICE_MODIFY_LIVE
VIR_DOMAIN_DEVICE_MODIFY_CONFIG
And modify internal codes to use virDomainModificationImpact.
If we can choose live or config when setting, then we need to
be able to choose which one we are querying.
Also, make the documentation clear that set must use a non-empty
subset (some of the hypervisors fail if params is NULL).
* include/libvirt/libvirt.h.in
(virDomainGetSchedulerParametersFlags): New prototype.
* src/libvirt.c (virDomainGetSchedulerParametersFlags): Implement
it.
* src/libvirt_public.syms: Export it.
* python/generator.py (skip_impl): Don't auto-generate.
* src/driver.h (virDrvDomainGetSchedulerParametersFlags): New
callback.
The new type is identical to the three old types that it replaces,
and by creating a common type, this allows future patches to share
common code that manipulates typed parameters.
This change is backwards-compatible in API (recompilation works
without any edits) and ABI (an older client that has not been
recompiled uses the same layout) for code using only public
names; only code using private names (those beginning with _)
will have to adapt.
* include/libvirt/libvirt.h.in (virTypedParameterType)
(VIR_TYPED_PARAM_FIELD_LENGTH, _virTypedParameter): New enum,
macro, and type.
(virSchedParameter, virBlkioParameter, virMemoryParameter):
Rewrite in terms of a common type, while keeping all old public
names for backwards compatibility.
(struct _virSchedParameter, struct _virBlkioParameter)
(struct _virMemoryParameter): Delete - these are private names.
* python/generator.py (enum): Cope with the refactoring.
This partially reverts (and fixes that part in a different way) commit
e4384459c93e3e786aa483c7f077d1d22148f689, which replaced
``/usr/bin/python'' with ``/usr/bin/env python'' in all examples or
scripts used during build to generate other files.
However, python bindings module is compiled and linked against a
specific python discovered or explicitly provided in configure phase.
Thus libvirt.py, which is generated and installed into the system,
should use the same python binary for which the module has been built.
The hunk in Makefile.am replaces $(srcdir) with $(PYTHON), which might
seem wrong but it is not. generator.py didn't use any of its command
line arguments so passing $(srcdir) to it was redundant.
This is more flexible regarding the location of the python binary
but doesn't allow to pass the -u flag. The -i flag can be passed
from inside the script using the PYTHONINSPECT env variable.
This fixes a problem with the esx_vi_generator.py on FreeBSD.
This patch adds a structure virMemoryParameter, it contains the name of
the
parameter and the type of the parameter along with a union.
dv:
+ rename enums to VIR_DOMAIN_MEMORY_PARAM_*
+ remove some extraneous tabs
v4:
+ Add unsigned int flags to the public api for future extensions
v3:
+ Protoype for virDomainGetMemoryParameters and dummy python binding.
v2:
+ Includes dummy python bindings for the library to build cleanly.
+ Define string constants like "hard_limit", etc.
+ re-order this patch.
This involved a few fixes. To start with,
an virDomainSnapshot object is really tied to a
domain, not a connection, so we have to generate
a slightly different object so that we can get
at self._dom for the object.
Next, we had to "dummy" up an override piece of
XML with a bogus argument that the function doesn't
actually take. That's so that the generator places
virDomainRevertToSnapshot underneath the correct
class (namely, the virDomain class).
Finally, we had to hand-implement the
virDomainRevertToSnapshot implementation, ignoring the
bogus pointer we are being passed.
With all of this in place, I was able to successfully
take a snapshot and revert to it using only the
Python bindings.

This binds the virDomainGetBlockInfo API to python's blockInfo
method on the domain object

>>> f = d.blockInfo("/dev/loop0", 0)

* python/libvirt-override.c: Manual impl of virDomainGetBlockInfo
The generator code was totally wrong for the virDomainSnapshot
APIs, not generating the wrapper class, and giving methods the
wrong names
* generator.py: Set metadata for virDomainSnapshot type & APIs

This patch implements the core driver and provides
- management functionality for managing the filter XMLs
- compiling the internal filter representation into ebtables rules
- applying ebtables rules on a network (tap,macvtap) interface
- tearing down ebtables rules that were applied on behalf of an
interface
- updating of filters while VMs are running and causing the firewalls to
be rebuilt

This introduces a new event type
VIR_DOMAIN_EVENT_ID_GRAPHICS
The same event can be emitted in 3 scenarios
typedef enum {
VIR_DOMAIN_EVENT_GRAPHICS_CONNECT = 0,
VIR_DOMAIN_EVENT_GRAPHICS_INITIALIZE,
VIR_DOMAIN_EVENT_GRAPHICS_DISCONNECT,
} virDomainEventGraphicsPhase;
Connect/disconnect are triggered at socket accept/close.
The initialize phase is immediately after the protocol
setup and authentication has completed. ie when the
client is authorized and about to start interacting with
the graphical desktop
This event comes with *a lot* of potential information
- IP address, port & address family of client
- IP address, port & address family of server
- Authentication scheme (arbitrary string)
- Authenticated subject identity. A subject may have
multiple identities with some authentication schemes.
For example, vencrypt+sasl results in a x509dname
and saslUsername identities.
This results in a very complicated callback :-(
typedef enum {
VIR_DOMAIN_EVENT_GRAPHICS_ADDRESS_IPV4,
VIR_DOMAIN_EVENT_GRAPHICS_ADDRESS_IPV6,
} virDomainEventGraphicsAddressType;
struct _virDomainEventGraphicsAddress {
int family;
const char *node;
const char *service;
};
typedef struct _virDomainEventGraphicsAddress virDomainEventGraphicsAddress;
typedef virDomainEventGraphicsAddress *virDomainEventGraphicsAddressPtr;
struct _virDomainEventGraphicsSubject {
int nidentity;
struct {
const char *type;
const char *name;
} *identities;
};
typedef struct _virDomainEventGraphicsSubject virDomainEventGraphicsSubject;
typedef virDomainEventGraphicsSubject *virDomainEventGraphicsSubjectPtr;
typedef void (*virConnectDomainEventGraphicsCallback)(virConnectPtr conn,
virDomainPtr dom,
int phase,
virDomainEventGraphicsAddressPtr local,
virDomainEventGraphicsAddressPtr remote,
const char *authScheme,
virDomainEventGraphicsSubjectPtr subject,
void *opaque);
The wire protocol is similarly complex
struct remote_domain_event_graphics_address {
int family;
remote_nonnull_string node;
remote_nonnull_string service;
};
const REMOTE_DOMAIN_EVENT_GRAPHICS_IDENTITY_MAX = 20;
struct remote_domain_event_graphics_identity {
remote_nonnull_string type;
remote_nonnull_string name;
};
struct remote_domain_event_graphics_msg {
remote_nonnull_domain dom;
int phase;
remote_domain_event_graphics_address local;
remote_domain_event_graphics_address remote;
remote_nonnull_string authScheme;
remote_domain_event_graphics_identity subject<REMOTE_DOMAIN_EVENT_GRAPHICS_IDENTITY_MAX>;
};
This is currently implemented in QEMU for the VNC graphics
protocol, but designed to be usable with SPICE graphics in
the future too.

This introduces a new event type
VIR_DOMAIN_EVENT_ID_IO_ERROR
This event includes the action that is about to be taken
as a result of the watchdog triggering
typedef enum {
VIR_DOMAIN_EVENT_IO_ERROR_NONE = 0,
VIR_DOMAIN_EVENT_IO_ERROR_PAUSE,
VIR_DOMAIN_EVENT_IO_ERROR_REPORT,
} virDomainEventIOErrorAction;
In addition it has the source path of the disk that had the
error and its unique device alias. It does not include the
target device name (/dev/sda), since this would preclude
triggering IO errors from other file backed devices (eg
serial ports connected to a file)
Thus there is a new callback definition for this event type
typedef void (*virConnectDomainEventIOErrorCallback)(virConnectPtr conn,
virDomainPtr dom,
const char *srcPath,
const char *devAlias,
int action,
void *opaque);
This is currently wired up to the QEMU block IO error events

VIR_DOMAIN_EVENT_ID_WATCHDOG
This event includes the action that is about to be taken
as a result of the watchdog triggering
typedef enum {
VIR_DOMAIN_EVENT_WATCHDOG_NONE = 0,
VIR_DOMAIN_EVENT_WATCHDOG_PAUSE,

This event includes the new UTC offset measured in seconds.
Thus there is a new callback definition for this event type
typedef void (*virConnectDomainEventRTCChangeCallback)(virConnectPtr conn,
virDomainPtr dom,
long long utcoffset,
void *opaque);
If the guest XML configuration for the <clock> is set to
offset='variable', then the XML will automatically be
updated with the new UTC offset value. This ensures that
during migration/save/restore the new offset is preserved.

The current API for domain events has a number of problems
- Only allows for domain lifecycle change events
- Does not allow the same callback to be registered multiple times
- Does not allow filtering of events to a specific domain
This introduces a new more general purpose domain events API
typedef enum {
VIR_DOMAIN_EVENT_ID_LIFECYCLE = 0, /* virConnectDomainEventCallback */
...more events later..
}
int virConnectDomainEventRegisterAny(virConnectPtr conn,
virDomainPtr dom, /* Optional, to filter */
int eventID,
virConnectDomainEventGenericCallback cb,
void *opaque,
virFreeCallback freecb);
int virConnectDomainEventDeregisterAny(virConnectPtr conn,
int callbackID);
Since different event types can received different data in the callback,
the API is defined with a generic callback. Specific events will each
have a custom signature for their callback. Thus when registering an
event it is neccessary to cast the callback to the generic signature
eg
int myDomainEventCallback(virConnectPtr conn,
virDomainPtr dom,
int event,
int detail,
void *opaque)
{
...
}
virConnectDomainEventRegisterAny(conn, NULL,
VIR_DOMAIN_EVENT_ID_LIFECYCLE,
VIR_DOMAIN_EVENT_CALLBACK(myDomainEventCallback)
NULL, NULL);
The VIR_DOMAIN_EVENT_CALLBACK() macro simply does a "bad" cast
to the generic signature
* include/libvirt/libvirt.h.in: Define new APIs for registering
domain events
* src/driver.h: Internal driver entry points for new events APIs
* src/libvirt.c: Wire up public API to driver API for events APIs

src/xenapi/xenapi_driver.c: Stub out new API entries
Introduce a new public API that provides a way to get progress
info on currently running jobs on a virDomainpPtr. APIs that
are initially within scope of this idea are
virDomainMigrate
virDomainMigrateToURI
virDomainSave
virDomainRestore
virDomainCoreDump
These all take a potentially long time and benefit from monitoring.
The virDomainJobInfo struct allows for various pieces of information
to be reported
- Percentage completion
- Time
- Overall data
- Guest memory data
- Guest disk/file data
* include/libvirt/libvirt.h.in: Add virDomainGetJobInfo
* python/generator.py, python/libvirt-override-api.xml,
python/libvirt-override.c: Override for virDomainGetJobInfo API
* python/typewrappers.c, python/typewrappers.h: Introduce wrapper
for unsigned long long type
The recent commit to implement a python version of this function
didn't drop an explicit 'ignore' check in the generator, so this
never ended up in the bindings.
adds a new python API call for retrieving the running
hypervisor version used by a connection: virConnectGetVersion
* python/generator.py: skip virConnectGetVersion from autogenerated
* python/libvirt-override-api.xml python/libvirt-override.c: define
direct native bindings
Enable virDomainMemoryStats in the python API. dom.memoryStats() will return a
dictionary containing the supported statistics. A dictionary is required
because the meaining of each quantity cannot be inferred from its index in a
list.
* python/generator.py: reenable bindings for this entry point
* python/libvirt-override-api.xml python/libvirt-override.c: the
generator can't handle this new function, add the new binding,
and the XML description
Set up the types for the domainMemoryStats function and insert it into the
virDriver structure definition. Because of static initializers, update
every driver and set the new field to NULL.
* include/libvirt/libvirt.h.in: new API
* src/driver.h src/*/*_driver.c src/vbox/vbox_tmpl.c: add the new
entry to the driver structure
* python/generator.py: fix compiler errors, the actual python binding is

* python/generator.py python/libvirt-override-api.xml
python/libvirt-override.c: implement the bindings for
virConnectListInterfaces() and virConnectListDefinedInterfaces()
There is currently no way to determine the libvirt version of a remote
libvirtd we are connected to. This is a useful piece of data to enable
feature detection.
A mistake in the generator was causing virInterface methods to be generated
with unpredicatable names ('ceUndefine', instead of just 'undefine'). This
fixes the method names to match existing convention.
Does anyone care if we are breaking API compat? My guess is that no one is
using the python interface bindings yet.
