Make testObjectEventQueue tolerant to NULL @event and move it so that it
does not require a prototype. Additionally we are now able to remove
locking when accessing driver->eventState, since it's using self-locking
APIs and the pointer is immutable.
When migration fails in qemuMigrationPrepareAny, we unconditionally call
qemuDomainRemoveInactive, which should only be called for transient
domains. The check for !vm->persistent was accidentally removed by
commit 540c339.

We already enable the parser option to detect invalid UTF-8, but
didn't test it. Also, JSON states that behavior of an object
with a duplicated key is undefined; we chose to reject it, but
were not testing it.
With the enhanced tests in place, we can simplify yajl2
initialization by relying on parser defaults being sane.

Yajl 2 has a nice feature that it can be configured whether to
allow multiple JSON objects parsed from a single stream, defaulting
to off. And yajl 1.0.12 at least provided a way to tell if all
input bytes were parsed, or if trailing bytes remained after a
valid JSON object was parsed. But we target RHEL 6 yajl 1.0.7,
which has neither of these. So fake it by always parsing '[...]'
instead, so that trailing garbage either trips up the array parse,
or is easily detected when unwrapping the result.

We have been allowing javascript style comments in JSON ever

(or even make it conditional, by adding a bool parameter to
the libvirt entry point).

Commit ceb496e5 fails on RHEL 6, with yajl 1.0.7, because that
version of yajl returns yajl_status_insufficient_data when the
parser is waiting for the rest of a token (this enum value was
dropped in yajl 2, so we have to wrap it). It also exposes a
problem where older yajl silently ignores trailing garbage after
a successful parse, so this patch works around that by changing
the testsuite. Another more invasive patch can add tighter
semantics to json parsing, but this is sufficient for a minimal
clean backport.
While touching this, fix up our error message cleanup. Yajl
documents that error messages produced by yajl_get_error()
MUST be cleaned with yajl_free_error(); this is certainly
true if we were to pass non-NULL allocator callbacks during
yajl_alloc(), but probably harmless in our usage of passing
NULL. But better safe than sorry.
* src/util/virjson.c (virJSONValueFromString): Allow different

In this patch we add VIR_DOMAIN_DEVICE_NET handlers implementation
for domainAttachDevice and domainDetachDevice callbacks.
As soon as we don't support this operation for hypervisor type domains,
we implement this functionality for containers only.
In detach procedure we find network device by MAC address.
Because PrlVmDevNet_GetMacAddress() returns MAC as a UTF-8 encoded
null-terminated string, we use memcmp() to compare it.
Also we remove corresponding virtual network by prlsdkDelNetAdapter call.

Rather than ignore the return status from virStorageBackendSCSIFindLUs,
cause a failure to start the pool if a -1 is returned. Issue was noted
during testing of the bz for iscsi that 'scsi' and 'fc' pools don't fail.
There are two macros used in the test: CAPSCOMP and CAPS_EXPECT_ERR.
Both run a test case and if a failure occurred, they set the @ret
variable to a value of -1 to indicate an error. Well, that's what they
should do. Due to a typo, they set the variable to a positive one
effectively masking any failed test.
Then, we have couple of tests failing. Fix them too.

Commit id '1feaccf0' attempted to handle an empty secrettype value; however,
it made a mistake by processing the secretType as if it was the original
secrettype string. The 'secretType' is actually whether 'usage' or 'uuid'
was used.
Thus adjust part of the change to make the same check for def->src->type !=
VIR_STORAGE_TYPE_VOLUME before setting auth_secret_usage from the
secrettype field.
Luckily the aforementioned commits misdeed would be overwritten by the

Commit id '832a9256' adjusted the code to recognize when the default
type of "unknown" was provided as the format type and to use "dos" if
found. Since the pool is built with "dos" and it could cause some
confusion when formatting the XML after building by seeing "unknown"
in the output, let's just adjust the pool's setting to "dos" so that
subsequent formats will see the value.
Currently the grammar uses "none" for a "valid" Disk Storage Pool
format type; however, virStoragePoolFormatDisk uses "unknown" so
virt-xml-validate will fail to validate when "unknown" is found
By trying to lead the way of clean includes, I sorted the lines
alphabetically and that is a problem for mingw builds with gnulib.
As 'configmake.h' defines DATADIR and 'datatypes.h' transitively
includes 'winsock.h' that uses 'DATADIR' as a name for a struct,
it's enough to reorder those.
Even though this might be worked around in gnulib later on, this
fixes the build for now.

Defining a domain with a SCSI disk attached via a hostdev
tag and a source address unit value longer than two digits
causes an error when editing the domain with virsh edit,
even if no changes are made to the domain definition.
The error suggests invalid XML, somewhere:
# virsh edit lmb_guest
error: XML document failed to validate against schema:
Unable to validate doc against /usr/local/share/libvirt/schemas/domain.rng
Extra element devices in interleave
Element domain failed to validate content
The virt-xml-validate tool fails with a similar error:
# virt-xml-validate lmb_guest.xml
Relax-NG validity error : Extra element devices in interleave
lmb_guest.xml:17: element devices: Relax-NG validity error :
Element domain failed to validate content
lmb_guest.xml fails to validate
The hostdev tag requires a source address to be specified,
which includes bus, target, and unit address attributes.
According to the SCSI Architecture Model spec (section
4.9 of SAM-2), a LUN address is 64 bits and thus could be
up to 20 decimal digits long. Unfortunately, the XML
schema limits this string to just two digits. Similarly,
the target field can be up to 32 bits in length, which
would be 10 decimal digits.

Since the reference unit and target fields are used in
several places in the XML schema, create a separate one
specific for SCSI Logical Units that will permit the
greater length. This permits both the validation utility
and the virsh edit command to succeed when a hostdev
tag is included.

I was adding a JSON test, and was shocked to find out our parser
treated the input string of "1" as invalid JSON. It turns out
that YAJL specifically documents that it buffers input, and that
if the last input read could be a prefix to a longer token, then
you have to explicitly tell the parser that the buffer has ended
before that token will be processed.
It doesn't help that yajl 2 renamed the function from what it was
in yajl 1.

If vm->def->cputune.nvcpupin is 0 in libxlDomainSetVcpuAffinities (as
seems to be the case on arm) then the VIR_FREE after cleanup: would be
operating on an uninitialised pointer in map.map.
Fix this by using libxl_bitmap_init and libxl_bitmap_dispose in the
appropriate places (like VIR_FREE, libxl_bitmap_dispose is also
idempotent, so there is no double free on exit from the loop).
libxl_bitmap_dispose is slightly preferable since it also sets
map.size back to 0, avoiding a potential source of confusion.
This fixes the crashes we've been seeing in the Xen automated tests on
ARM.
