We don't want to commit to the API yet before everything is worked out. Disable it for the 1.5 release. This commit is meant to be reverted after the 1.5 release. The disabling of the driver-specific options is achieved by applying the old checks while parsing the command line.

Test that qemu-img convert -c works when input image length is not a multiple of the cluster size. Previously an error message would be produced: qemu-img: error while compressing sector 0: Input/output error Now that qcow2 and qcow handle this case the test passes successfully.

If zero clusters are erroneously treated as unallocated, "qemu-img rebase" will copy the backing file's contents onto the cluster. The bug existed also in image streaming, but since the root cause was in qcow2's is_allocated implementation it is enough to test it with qemu-img.

Just create lots of images and try out each of the creation options that qcow2 provides (except backing_file/fmt for now) I'm not totally happy with the behaviour of qemu-img in each of the cases, but let's be explicit and update the test when we do change things later.

These check that a paused streaming job does not advance its offset. Sometimes the new test fails; the map is different between the source and the destination of the streaming because qemu-io does not always pack adjacent clusters that have the same allocated/unallocated state. However, this also happens with the existing test_stream testcase, and is better fixed in qemu-io.

Derived from the streaming test cases (030), this adds the following 9 tests: 1. For the following image chain, commit [mid] into [backing], and use qemu-io to verify [backing] has its original data, as well as the data from [mid] [backing] <-- [mid] <-- [test] 2. Verifies that 'block-commit' with the 'speed' parameter sets the speed parameter, as reported by 'query-block-jobs' 3. Verifies that a bogus 'device' parameter to 'block-commit' results in error 4-9: Appropriate error values returned for the following argument errors: * top == base * top is nonexistent * base is nonexistent * top == active layer (this is currently not supported) * top and base arguments are reversed * top argument is omitted Signed-off-by: NJeff Cody <jcody@redhat.com> Reviewed-by: NEric Blake <eblake@redhat.com> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

This tests establishes the basic post-conditions of the qcow2 lazy refcounts features: 1. If the image was closed normally, it is marked clean. 2. If an allocating write was performed and the image was not closed normally, then it is marked dirty. a. Written data can be read back successfully. b. The image file can be repaired and will be marked clean again. c. The image file is automatically repaired when opened read/write.

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.

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.

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.
