14062e6fe5 internal: Introduce virCheckNonEmptyStringArgGoto and reuse it
The helper makes sure that strings passed to APIs are non-NULL and
non-empty. This allows to drop some inlined checks where it does not
make sense.

d637017f9b vz: Fix build after recent commit
Function prlsdkGetStatsParam was missing a prototype or the static

1. Use vzDomObjFromDomainRef/virDomainObjEndAPI pair to get domain

comments.

2. Balloon statistics is not applicable to containers. Fault

In my previous fix (1310b1358) I've tried to solve an ordering

70d75ffc79 qemuBuildMemoryBackendStr: Honour passed @pagesize
So far the argument has not much meaning and was practically ignored.
This is not good since when doing memory hotplug, the size of desired
hugepage backing is passed in that argument. Taking closer look at the
tests I'm fixing reveals the bug. For instance, while the following is
in the test:

    <memory model='dimm'>
      <source>
        <nodemask>1-3</nodemask>
        <pagesize unit='KiB'>4096</pagesize>
      </source>
      <target>
        <size unit='KiB'>524287</size>
        <node>0</node>
      </target>
      <address type='dimm' slot='0' base='0x100000000'/>
    </memory>

the generated commandline corresponding to this XML was:

    -object memory-backend-ram,id=memdimm0,size=536870912,\
    host-nodes=1-3,policy=bind

Have you noticed? Yes, memory-backend-ram! Nothing can be further away
from the right answer. The hugepage backing is requested in the XML
and we happily ignore it. This is just not right. It's
memory-backend-file which should have been used:

    -object memory-backend-file,id=memdimm0,prealloc=yes,\
    mem-path=/dev/hugepages4M/libvirt/qemu,size=536870912,\
    host-nodes=1-3,policy=bind

The problem is, that @pagesize passed to qemuBuildMemoryBackendStr
(where this part of commandline is built) was ignored. The hugepage to
back memory was searched only and only by NUMA nodes pinning. This
works only for regular guest NUMA nodes.

Then, I'm changing the hugepages size in the test XMLs too. This is
simply because in the test suite we create dummy mount points just for
2M and 1G hugepages. And in the test 4M was requested. I'm sticking to
2M, but 1G should just work too.

f8e9deb1d4 qemuBuildMemoryBackendStr: Fix hugepages lookup process
https://bugzilla.redhat.com/show_bug.cgi?id=1196644

This function constructs the backend (host facing) part of the
memory device.  At the beginning, the configured hugepages are
searched to find the best match for given guest NUMA node.
Configured hugepages can have a @nodeset attribute to specify on
which guest NUMA nodes should be the hugepages backing used.
There is, however, one 'corner case'. Users may just tell 'use
hugepages to back all the nodes'. In other words:

  <memoryBacking>
    <hugepages/>
  </memoryBacking>

  <cpu>
    <numa>
      <cell id='0' cpus='0-1' memory='1024000' unit='KiB'/>
    </numa>
  </cpu>

Our code fails in this case. Well, since there's no @nodeset (nor
any <page/> child element to <hugepages/>) we fail to lookup the
default hugepage size to use.

cb005533ab json: enhance parser test

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.

7cd991b74c json: reject trailing garbage
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.

* src/util/virjson.c (virJSONValueFromString): With older json,
wrap text to avoid trailing garbage.
* tests/jsontest.c (mymain): Add tests for this.

the libvirt entry point).

f2acaebd40 json: cope with older yajl semantics
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
error code.  Use canonical cleanup of error message.
(VIR_YAJL_STATUS_OK): New helper macro.
* tests/jsontest.c (mymain): Wrap text to avoid difference in
trailing garbage handling

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.
