2012-02-23qemu-iotests: Update rbd supportJosh Durgin1-1/+1
rbd implements bdrv_truncate, so test 025 will work. Signed-off-by: Josh Durgin <josh.durgin@dreamhost.com> Signed-off-by: Christoph Hellwig <hch@lst.de>

2012-02-23qemu-iotests: only run 016 for file and sheepdog protocolsChristoph Hellwig1-2/+1
016 writes past EOF which isn't support by most protocols, so limit it to file and sheepdog, which explicitly support it. Pointed out by Josh Durgin <josh.durgin@dreamhost.com>. Signed-off-by: Christoph Hellwig <hch@lst.de>
2012-02-23qemu-iotests: Use zero-based offsets for IO patternsStefan Hajnoczi12-1863/+1873
The io_pattern style functions have the following loop: for i in `seq 1 $count`; do echo ... $(( start + i * step )) ... done Offsets are 1-based so start=1024, step=512, count=4 yields: 1536, 2048, 2560, 3072 Normally we expect: 1024, 1536, 2048, 2560 Most tests ignore this detail, which means that they perform I/O to a slightly different range than expected by the test author. Later on things got less innocent and tests started trying to compensate for the 1-based indexing. This included negative start values in test 024 and my own attempt with count-1 in test 028! The end result is that tests that use io_pattern are hard to reason about and don't work the way you'd expect. It's time to clean this mess up. This patch switches io_pattern to 0-based offsets. This requires adjusting the golden outputs since I/O ranges are now shifted and output differs. Verifying these output diffs is easy, however. Each diff hunk moves one I/O from beyond the end of the pattern range to the beginning. Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> Signed-off-by: Christoph Hellwig <hch@lst.de>
2012-02-23qemu-iotests: add support for rbd and sheepdog protocolsMORITA Kazutaka31-4/+89

2012-02-23qemu-iotests: filter IMGFMT correctly in 019Stefan Hajnoczi3-4/+10
Test 019 can be run with qcow2 and qed image formats. Replace the specific image format value with "IMGFMT" so the golden output does not hardcode qcow2 or qed. This patch also includes a typo fix for "occurrences". Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> Signed-off-by: Christoph Hellwig <hch@lst.de>

2012-02-22qemu-iotests: update expected results after qemu-img changesKevin Wolf1-30/+90
The error message for leaked clusters has changed. qemu-iotests needs to be updated to pass 026 again. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Christoph Hellwig <hch@lst.de>
2012-02-22qemu-iotests: add read/write from smaller backing image testStefan Hajnoczi3-0/+560
Some image formats support backing images that are smaller than the image file. This patch adds a test that verifies that reads and writes beyond the end of backing image work. Unallocated reads beyond the end of the backing file should produce zeroes. Writes beyond the end of the backing file should copy-on-write using zeroes.

2012-02-22qemu-iotests: add sub-cluster allocating write test for sparse image formatsStefan Hajnoczi3-0/+101
Image formats that grow the image file on demand and are organized into clusters must handle sub-cluster allocating writes. Such writes touch a portion of a previously unallocated data cluster. After the image file is grown with the written data, reads of that cluster should work as expected: 1. Sectors before the written region are zero. 2. The written region is present and the data is uncorrupted. 3. Sectors after the written region are zero.

2012-02-22qemu-iotests: improve test for qemu-img convert with backing fileKevin Wolf1-23/+36
Additionally to testing the qemu-img convert -B option, also test -o backing_file. Also, the old test acidentlly used a pattern of zeros for most of the writes, so that the allocation test didn't really work out. This is fixed by using an explicit pattern.

2012-02-22qemu-iotests: consider more cases in parsing qemu-io outputKevin Wolf1-1/+1
I got a bug report with test output diffs like this: -4 KiB, X ops; XX:XX:XX.X (XXX YYY/sec and XXX ops/sec) +4 KiB, 1 ops; 0.0000 sec (inf EiB/sec and inf ops/sec) This patch extends the regular expression to consider terabytes, petabytes and exabytes, and to allow inf as value for the throughput.

2012-02-22qemu-iotests: explicitly use bash interpreterStefan Hajnoczi30-30/+30

2012-02-22qemu-iotests: test larger clusters sizes on qcow2Kevin Wolf7-818/+26645
This patch adds test case 023 which tests some more cluster sizes. For anythinger larger than 4k clusters we can't use requests that are l2_size or more (128k for 1k clusters, 2 MB for 4k clusters, 512 MB for 64k clusters). Therefore one of the common.pattern cases is changed and needs new expected results for some old test cases. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Christoph Hellwig <hch@lst.de>

2012-02-22qemu-iotests: align test requests according to cluster sizeKevin Wolf10-42/+59
Change the io_test and io_test2 functions to take the cluster size of the image and the number of test requests to issue. Tests are changed to specify a cluster size (usually 4k), but expected test results stay the same for now (apart from qemu-img printing the cluster size now).

2012-02-22qemu-iotests: fix pattern for write testStefan Weil1-1/+1
The write pattern value 0axb is invalid and evaluates to 0, so the read check (which uses a correct value of 0xab) will fail. This failure will only be detected with a separate patch for qemu-io. Without it, qemu-io cannot interpret hex values and always uses a pattern value of 0. Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Christoph Hellwig <hch@lst.de>
