2013-07-04add a header file for atomic operationsPaolo Bonzini
We're already using them in several places, but __sync builtins are just too ugly to type, and do not provide seqcst load/store operations. Reviewed-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2013-07-02int128: optimize and add test casesPaolo Bonzini
For add, the carry only requires checking one of the arguments. For sub and neg, we can similarly optimize computation of the carry. For ge, we can just do lexicographic order. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2013-06-28qemu-iotests: extract wait_until_completed() into iotests.pyStefan Hajnoczi
The 'drive-mirror' tests often issue 'block-job-complete' and wait for the QMP completion event. Other types of block jobs also want to wait for completion but they may not need to issue 'block-job-complete'. Extract wait_until_completed() from 041 and put it into iotests.py. Return the QMP event object so the caller can make additional assertions, if necessary. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2013-06-14ide-test: fix failure for test_flushMichael Roth
bd07684aacfb61668ae2c25b7dd00b64f3d7c7f3 added a test to ensure BSY flag is set when a flush request is in flight. It does this by setting a blkdebug breakpoint on flush_to_os before issuing a CMD_FLUSH_CACHE. It then resumes CMD_FLUSH_CACHE operation and checks that BSY is unset. The actual unsetting of BSY does not occur until ide_flush_cb gets called in a bh, however, so in some cases this check will race with the actual completion. Fix this by polling the ide status register until BSY flag gets unset before we do our final sanity checks. According to f68ec8379e88502b4841a110c070e9b118d3151c this is in line with how a guest would determine whether or not the device is still busy.

2013-06-04qemu-iotests: make compare_images() commonStefan Hajnoczi
The iotests.compare_images() function returns True if two image files have the identical data. Previously this was implemented by converting images to raw and then comparing their contents using Python. Since "qemu-img compare" is now available and is more efficient, switch to it.

2013-05-30qapi: pad GenericList value fields to 64 bitsMichael Roth
With the introduction of native list types, we now have types such as int64List where the 'value' field is not a pointer, but the actual 64-bit value. On 32-bit architectures, this can lead to situations where 'next' field offset in GenericList does not correspond to the 'next' field in the types that we cast to GenericList when using the visit_next_list() interface, causing issues when we attempt to traverse linked list structures of these types. To fix this, pad the 'value' field of GenericList and other schema-defined/native *List types out to 64-bits. This is less memory-efficient for 32-bit architectures, but allows us to continue to rely on list-handling interfaces that target GenericList to simply visitor implementations. In the future we can improve efficiency by defaulting to using native C array backends to handle list of non-pointer types, which would be more memory efficient in itself and allow us to roll back this change.

2013-05-29tests: set MALLOC_PERTURB_ to expose memory bugsStefan Hajnoczi
glibc wipes malloc(3) memory when the MALLOC_PERTURB_ environment variable is set. The value of the environment variable determines the bit pattern used to wipe memory. For more information, see http://udrepper.livejournal.com/11429.html. Set MALLOC_PERTURB_ for gtester and qemu-iotests. Note we pick a random value from 1 to 255 to expose more bugs. If you need to reproduce a crash use 'show environment' in gdb to extract the MALLOC_PERTURB_ value from a core dump. Both make check and qemu-iotests pass with MALLOC_PERTURB_ enabled.

2013-05-15qapi: fix leak in unit testsMichael Roth
qmp_output_get_qobject() increments the qobject's reference count. Since we currently pass this straight into qobject_to_json() so we can feed the data into a QMP input visitor, we never actually free the underlying qobject when qmp_output_visitor_cleanup() is called. This causes leaks on all of the QMP serialization tests. Fix this by holding a pointer to the qobject and decref'ing it before returning from qmp_deserialize().
