2016-04-15qemu-iotests: tests: do not set unused tmp variableSascha Silbe1-1/+0
The previous commit removed the last usage of ${tmp} inside the tests themselves; the only remaining users are sourced by check. So we can now drop this variable from the tests.

2016-01-20qemu-iotests: Reduce racy output in 028Eric Blake1-2/+4
On my machine, './check -qcow2 028' was failing about 80% of the time, due to a race in how many times the repeated attempts to run 'info block-jobs' could occur before the job was done, showing up as a failure of fewer '(qemu) ' prompts than in the expected output. Silence the output during the repetitions, then add a final clean command to keep the expected output useful; once patched, I was finally able to run the test 20 times in a row with no failures.

2014-08-20qemu-iotests: Fix 028 reference output for qedKevin Wolf1-0/+1
We need to filter out driver-specific options in the "Formatting..." string printed by qemu when creating the backup image. Reported-by: Peter Wu <peter@lekensteyn.nl> Signed-off-by: Kevin Wolf <kwolf@redhat.com> Tested-by: Peter Wu <peter@lekensteyn.nl>
2014-07-18qemu-iotests: fix 028 failure due to disk image pathStefan Hajnoczi1-1/+3
The disk image path is echoed by QEMU's readline when the "drive_backup disk ${TEST_IMG}.copy" HMP command is issued. Unfortunately it is very hard to filter out the path due to readline's character-by-character output (with terminal escape sequences). Just redirect this command to /dev/null for now.

2014-07-09block/backup: Fix hang for unaligned image sizeKevin Wolf1-1/+26
When doing a block backup of an image with an unaligned size (with respect to the BACKUP_CLUSTER_SIZE), qemu would check the allocation status of sectors after the end of the image. bdrv_is_allocated() returns a result that is valid for 0 sectors in this case, so the backup job ran into an endless loop. Stop looping when seeing a result valid for 0 sectors, we're at EOF then. The test case looks somewhat unrelated at first sight because I originally tried to reproduce a different suspected bug that turned out to not exist. Still a good test case and it accidentally found this one. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com>
2014-02-09qemu-iotests: change _supported_proto to file for various testsPeter Lieven1-1/+1
all these tests do anything of the following and thus fail with any protocol other than file: - the tests use rm, cp or mv shell commands which only work on file - the tests use qcow2.py - the images construct new filenames (e.g. backing file names) and the logic is broken for anything else than file Signed-off-by: Peter Lieven <pl@kamp.de> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2012-02-29qemu-iotests: Test rebase with short backing fileKevin Wolf1-0/+5
This tests that qemu-img rebase doesn't assume that the backing file has the same size as the image, but considers that it can be smaller. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Reviewed-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>
2012-02-23qemu-iotests: Use zero-based offsets for IO patternsStefan Hajnoczi1-5/+5
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>

2012-02-22qemu-iotests: add read/write from smaller backing image testStefan Hajnoczi1-0/+101
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.
