6bdcef11e3 network: implement virNetworkUpdate for test_driver
The test driver does nothing outside of keeping track of each
network's config/state in the in-memory database maintained by
network_conf functions, so all we have to do is call the function that
updates the network's entry in the in-memory database.

f36309d688 network: utility functions for updating network config
These new functions are highly inspired by those in domain_conf.c (but
not identical), and are intended to make it simpler to update the
various combinations of live/persistent network configs.

The network driver wasn't previously as careful about the separation
between the live "status" in network->def and the persistent "config"
in network->newDef (or sometimes in network->def). This series
attempts to remedy some of that, but probably doesn't go all the way
(enough to get these functions working and enable continued work on
virNetworkUpdate though).

bridge_driver.c and test_driver.c were updated in a few places to take
advantage of the new functions and/or account for changes in argument
lists.

bb705e2519 Destroy virdomainlist.[ch]
As the consensus in:
https://www.redhat.com/archives/libvir-list/2012-July/msg01692.html,
this patch is to destroy conf/virdomainlist.[ch], folding the
helpers into conf/domain_conf.[ch].

* src/Makefile.am:
  - Various indention fixes incidentally
  - Add macro DATATYPES_SOURCES (datatypes.[ch])
  - Link datatypes.[ch] for libvirt_lxc

* src/conf/domain_conf.c:
  - Move all the stuffs from virdomainlist.c into it
  - Use virUnrefDomain and virUnrefDomainSnapshot instead of
    virDomainFree and virDomainSnapshotFree, which are defined
    in libvirt.c, and we don't want to link to it.
  - Remove "if" before "free" the object, as virObjectUnref
    is in the list "useless_free_options".

768007aedc maint: don't permit format strings without %
Any time we have a string with no % passed through gettext, a
translator can inject a % to cause a stack overread.  When there
is nothing to format, it's easier to ask for a string that cannot
be used as a formatter, by using a trivial "%s" format instead.

In the past, we have used --disable-nls to catch some of the
offenders, but that doesn't get run very often, and many more
uses have crept in.  Syntax check to the rescue!

The syntax check can catch uses such as
virReportError(code,
               _("split "
                 "string"));
by using a sed script to fold context lines into one pattern
space before checking for a string without %.

33dc8cf018 drivers: Implement virListAllDomains for drivers using virDomainObj
This patch adds support for listing all domains into drivers that use
the common virDomainObj implementation: libxl, lxc, openvz, qemu, test,
uml, vmware.

For drivers that don't support managed save images the guests are
treated as if they had none, so filtering guests that do have such an
image on this driver succeeds and produces 0 results.

4010217e73 test: Set the fixed uuid for the default XMLs
The objects (domain, pool, network, etc) for testing are defined/
started each time when opening a connect to test driver, and thus
the UUID for the objects will be generated each time, with different
values. e.g.

% for i in {1..3}; do ./tools/virsh --connect \
  test:///default dumpxml test | grep uuid; done
  <uuid>a1b6ee1f-97de-f0ee-617a-0cdb74947df5</uuid>

  <uuid>fecb1d3a-918a-8412-e534-76192cf32b18</uuid>

It's the potential bug which can cause operations like below to fail:

$ virsh -c test:///default dumpxml test > test.xml

[ Some modificatons, though it's not supported, but it should work ]

$ virsh -c test:///default define test.xml

This patch set fixed UUID for objects which support it. (domain,
pool, network).

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                            \

73b9977140 xml: use long long internally, to centralize overflow checks
On 64-bit platforms, unsigned long and unsigned long long are
identical, so we don't have to worry about overflow checks.
On 32-bit platforms, anywhere we narrow unsigned long long back
to unsigned long, we have to worry about overflow; it's easier
to do this in one place by having most of the code use the same
or wider types, and only doing the narrowing at the last minute.
Therefore, the memory set commands remain unsigned long, and
the memory get command now centralizes the overflow check into
libvirt.c, so that drivers don't have to repeat the work.

This also fixes a bug where xen returned the wrong value on
failure (most APIs return -1 on failure, but getMaxMemory
must return 0 on failure).

7c90026db9 npiv: Auto-generate WWN if it's not specified
The auto-generated WWN comply with the new addressing schema of WWN:

<quote>
the first nibble is either hex 5 or 6 followed by a 3-byte vendor
identifier and 36 bits for a vendor-specified serial number.
</quote>

We choose hex 5 for the first nibble. And for the 3-bytes vendor ID,
we uses the OUI according to underlying hypervisor type, (invoking
virConnectGetType to get the virt type). e.g. If virConnectGetType
returns "QEMU", we use Qumranet's OUI (00:1A:4A), if returns
ESX|VMWARE, we use VMWARE's OUI (00:05:69). Currently it only
supports qemu|xen|libxl|xenapi|hyperv|esx|vmware drivers. The last
36 bits are auto-generated.

707781fe12 Only add the timer when a callback is registered
The lifetime of the virDomainEventState object is tied to
the lifetime of the driver, which in stateless drivers is
tied to the lifetime of the virConnectPtr.

If we add & remove a timer when allocating/freeing the
virDomainEventState object, we can get a situation where
the timer still triggers once after virDomainEventState
has been freed. The timeout callback can't keep a ref
on the event state though, since that would be a circular
reference.

The trick is to only register the timer when a callback
is registered with the event state & remove the timer
when the callback is unregistered.

The demo for the bug is to run

  while true ; do date ; ../tools/virsh -q -c test:///default 'shutdown test; undefine test; dominfo test' ; done

prior to this fix, it will frequently hang and / or
crash, or corrupt memory

34ad13536e Hide use of timers for domain event dispatch
Currently all drivers using domain events need to provide a callback
for handling a timer to dispatch events in a clean stack. There is
no technical reason for dispatch to go via driver specific code. It
could trivially be dispatched directly from the domain event code,
thus removing tedious boilerplate code from all drivers

Also fix the libxl & xen drivers to pass 'true' when creating the
virDomainEventState, since they run inside the daemon & thus always
expect events to be present.

d09f6ba5fe Return count of callbacks when registering callbacks
When registering a callback for a particular event some callers
need to know how many callbacks already exist for that event.

callbacks should return the count of callbacks. Also rename

f21d49144f test: fix potential lock corruption in test driver
In some error situations, the function testDomainRestoreFlags() could
unlock the test driver mutex without first locking it. This patch
moves the lock operation earlier, so that it occurs before any
potential jump down to the unlock call.

I found this problem while auditing the test driver lock usage to
determine the cause of a hang while running the following test:

  cd tests; while true; do printf x; ./undefine; done

This patch *does not* solve that problem, but we now understand its
actual source, and danpb is working on a patch.

c725e2dc5a blockstats: support lookup by path in blockstats
Commit 89b6284f made it possible to pass either a source name or
the target device to most API demanding a disk designation, but
forgot to update the documentation.  It also failed to update
virDomainBlockStats to take both forms. This patch fixes both the
documentation and the remaining function.

Xen continues to use just device shorthand (that is, I did not
implement path lookup there, since xen does not track a domain_conf
to quickly tie a path back to the device shorthand).

* src/libvirt.c (virDomainBlockStats, virDomainBlockStatsFlags)
(virDomainGetBlockInfo, virDomainBlockPeek)
(virDomainBlockJobAbort, virDomainGetBlockJobInfo)
(virDomainBlockJobSetSpeed, virDomainBlockPull): Document
acceptable disk naming conventions.
* src/qemu/qemu_driver.c (qemuDomainBlockStats)
(qemuDomainBlockStatsFlags): Allow lookup by source name.
* src/test/test_driver.c (testDomainBlockStats): Likewise.

209c2880b9 Fix default console type setting
The default console type may vary based on the OS type. ie a Xen
paravirt guests wants a 'xen' console, while a fullvirt guests
wants a 'serial' console.

A plain integer default console type in the capabilities does
not suffice. Instead introduce a callback that is passed the
OS type.

* src/conf/capabilities.h: Use a callback for default console
  type
* src/conf/domain_conf.c, src/conf/domain_conf.h: Use callback
  for default console type. Add missing LXC/OpenVZ console types.

59d042871c vcpu: teach getVcpusFlags about current
Now that virDomainSetVcpusFlags knows about VIR_DOMAIN_AFFECT_CURRENT,
so should virDomainGetVcpusFlags.

Unfortunately, the virsh counterpart 'virsh vcpucount' has already
commandeered --current for a different meaning, so teaching virsh
to expose this in the next patch will require a bit of care.

b1083a4c53 save: wire up trivial save/restore flags implementations
For all hypervisors that support save and restore, the new API
now performs the same functions as the old.

VBox is excluded from this list, because its existing domainsave
is broken (there is no corresponding domainrestore, and there
is no control over the filename used in the save).  A later
patch should change vbox to use its implementation for
managedsave, and teach start to use managedsave results.

461e0f1a2d flags: use common dumpxml flags check
The previous patches only cleaned up ATTRIBUTE_UNUSED flags cases;
auditing the drivers found other places where flags was being used
