Author: Daniel P. Berrange <berrange@redhat.com>
Date: Wed May 9 15:18:56 2012 +0100
Allow stack traces to be included with log messages
Sometimes it is useful to see the callpath for log messages.
This change enhances the log filter syntax so that stack traces
can be show by setting '1:+NAME' instead of '1:NAME'.
With the huge & ever increasing number of logging statements per file,
this will be incredibly verbose and have a major performance penalty.
This makes the feature impractical to use widely and as such it is not
worth the code maint cost.
Removing this seldom used feature allows us to drop the 'execinfo'
module in gnulib which provides the backtrace() function which doesn't
exist on non-Linux.
Users who want to get stack traces of parts of libvirt can use GDB,
or systemtap for live tracing with minimal perf impact.

The Perl bindings for libvirt use the test driver for unit tests. This

The problem is that virFileActivateDirOverride is called by our various

uses libvirt.so
To deal with this we allow the LIBVIRT_DIR_OVERRIDE=1 env variable to be

will correctly resolve files to the source tree.

vircapstest has code to add a full host NUMA topology, that
is, one that includes all information about nodes and CPUs
including IDs; testQemuCapsInit(), which is used to create a
mock virCapsPtr for QEMU tests, however, just fakes it by
setting nnumaCell_max to some number.
While the latter approach has served us well so far, we're
going to need all the information to be filled in soon. In
order to do that, we can just move the existing code from
vircapstest to testutils and, with some renaming and
trivial tweaking, use it as-is.
Interestingly, the NUMA topology generated by the function
is rigged up so that the NUMA nodes aren't (necessarily)
numbered starting from 0, which is a nice way to spot
mistaken assumptions in our codebase.

Commit 8563560026 switched from

(fixedcontent is *sometimes* a copy of strcontent with a \n

test case output being a 0 length file.
This patch creates a new const char *cmpcontent initialized to
strcontent, but changed to fixedcontent if/when fixedcontent is
created, then always uses cmpcontent instead of (str|fixed)content.
Commit ca32929908 added function
virTestCompareToFile(), but forgot to use a fixedcontent value for the

<vcpu id='1' enabled='no' hotpluggable='yes'/>

The 'enabled' attribute allows to control the state of the vcpu.
'hotpluggable' controls whether given vcpu can be hotplugged and 'order'

Currently we spawn couple of binaries in our test suite.
Moreover, we provide some spoofed versions of system binaries
hoping that those will be executed instead of the system ones.
For instance, for testing SSH socket we have written our own ssh
binary for producing predictable results. We certainly don't want
to execute the system ssh binary.
However, in order to prefer our binaries over system ones, we
need to set PATH environment variable. But this is done only at
the Makefile level. So if anybody runs a test by hand that
expects our spoofed binary, the test ends up executing real
system binaries. This is not good. In fact, it's terribly wrong.
The fix lies in a small trick - putting our build directory at
the beginning of the PATH environment variable in each test.
Hopefully, since every test has this VIRT_TEST_MAIN* wrapper, we
can fix this at a single place.
Moreover, while this removes setting PATH for our tests written
in bash, it's safe as we are not calling anything ours that would
