2013-09-27qemu-iotests: Quote $TEST_IMG* and $TEST_DIR usageJeff Cody49-337/+337

2013-09-27qemu-iotests: Add basic ability to use binary sample imagesJeff Cody3-0/+35
For image formats that are not "QEMU native", but supported for compatibility, it is useful to verify that an image created with the 'gold standard' native tool can be read / written to successfully by QEMU. In addition to testing non-native images, this could also be useful to test against image files created by older versions of QEMU. This provides a directory to store small sample images, for use by scripts in tests/qemu-iotests. Image files should be compressed with bzip2. To use a sample image from a bash script, the _use_sample_img function will copy and decompress the image into $TEST_DIR, and set $TEST_IMG to be the decompressed sample image copy. To cleanup, call _cleanup_test_img as normal. Signed-off-by: Jeff Cody <jcody@redhat.com> Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2013-09-25qemu-iotests: Do not execute 052 with -nocacheMax Reitz1-0/+1
Test 052 uses qemu-io -s which will result in bdrv_open trying to create a temporary snapshot file in /tmp. However, since O_DIRECT and tmpfs do not work well together, disable this test for -nocache. Signed-off-by: Max Reitz <mreitz@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2013-09-25qemu-iotests: add test for backing file overridingFam Zheng2-1/+27
Test that backing.file.filename option can be parsed and override the backing file from image (backing file reflected with "info block"). Signed-off-by: Fam Zheng <famz@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2013-09-13qemu-iotests: Fix test 038Max Reitz2-6/+7
Test 038 uses asynchronous I/O, resulting (potentially) in a different output for every run (regarding the order of the I/O accesses). This can be fixed by simply sorting the I/O access messages, since their order is irrelevant anyway (for this asynchonous I/O).

2013-09-12qemu-iotests: Cleanup test image in test number 007Bharata B Rao1-1/+1
qemu-iotests number 007 doesn't do test image cleanup. This will affect those protocols that expect a clean state before every test. Hence ensure that test image is cleaned up in this test. Signed-off-by: Bharata B Rao <bharata@linux.vnet.ibm.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2013-09-12qemu-iotests: Adjustments due to error propagationMax Reitz6-40/+24
When opening/creating images, propagating errors instead of immediately emitting them on occurrence results in errors generally being printed on a single line rather than being split up into multiple ones. This in turn requires adjustments to some test results. Also, test 060 used a sed to filter out the test image directory and format by removing everything from the affected line after a certain keyword; this now also removes the error message itself, which can be fixed by using _filter_testdir and _filter_imgfmt. Finally, _make_test_img in common.rc did not filter out the test image directory etc. from stderr. This has been fixed through a redirection of stderr to stdout (which is already done in _check_test_img and _img_info). Signed-off-by: Max Reitz <mreitz@redhat.com>

2013-09-06qemu-iotests: Fixed test case 026Kevin Wolf3-17/+649
The reference output for test case 026 hasn't been updated in a long time and it's one of the "known failing" cases. This patch updates the reference output so that unintentional changes can be reliably detected again. The problem with this test case is that it produces different output depending on whether -nocache is used or not. The solution of this patch is to actually have two different reference outputs. If nnn.out.nocache exists, it is used as the reference output for -nocache; otherwise, nnn.out stays valid for both cases.

This is useful for targets such as rbd / ceph, where the target volume may already exist; we cannot always rely on qemu-img convert to create the image, as dependent on the output format, there may be parameters which are not possible to specify through the qemu-img convert command line.

We don't want to commit to the API yet before everything is worked out. Like already for 1.5, disable it again for the 1.6 release. This commit is meant to be reverted after the 1.6 release.

2013-07-15block: Don't parse protocol from file.filenameKevin Wolf2-0/+26
One of the major reasons for doing something new for -blockdev and blockdev-add was that the old block layer code parses filenames instead of just taking them literally. So we should really leave it untouched when it's passing using the new interfaces (like -drive file.filename=...). This allows opening relative file names that contain a colon.

2013-07-15blockdev: add sync mode to drive-backup QMP commandStefan Hajnoczi1-15/+21
The drive-backup command is similar to the drive-mirror command, except no guest data written after the command executes gets copied. Add a sync mode argument which determines whether the entire disk is copied, just allocated clusters, or only clusters being written to by the guest. Currently only sync mode 'full' is supported - it copies the entire disk. For read-only point-in-time snapshots we may only need sync mode 'none' since the target can be a qcow2 file using the guest's disk as its backing file (no need to copy the entire disk). Finally, sync mode 'top' is useful if we wish to preserve the backing chain. Note that this patch just adds the sync mode argument to drive-backup. It does not implement sync modes 'top' or 'none'. This patch is necessary so we can add a drive-backup HMP command that behaves like the existing drive-mirror HMP command and takes a sync mode.

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.

The iotests.compare_images() function returns True if two image files have the identical data.

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.
