python: improve conversion validation

2012-04-05T03:37:51+00:00

https://bugzilla.redhat.com/show_bug.cgi?id=807751

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.

Add support for event tray moved of removable disks

2012-03-26T06:07:06+00:00

https://bugzilla.redhat.com/show_bug.cgi?id=575160

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);

python: Expose virDomain{G,S}etInterfaceParameters APIs in python binding

2012-02-21T08:32:33+00:00

The v4 patch corrects indentation issues.

The v3 patch follows latest python binding codes and change 'size'
type from int to Py_ssize_t.

An simple example to show how to use it:

import libvirt

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

print dom.interfaceParameters('vnet0', 0)

params = {'outbound.peak': 10,
          'inbound.peak': 10,
          'inbound.burst': 20,
          'inbound.average': 20,
          'outbound.average': 30,
          'outbound.burst': 30}

print dom.setInterfaceParameters('vnet0', params, 0)
print dom.interfaceParameters('vnet0', 0)
