These series makes tests pass with IMGOPTS='compression_type=zstd'
Also, python iotests start to support IMGOPTS (they didn't before). v4: 18,19: new: add unsupported_imgopts as suggested by Hanna. Vladimir Sementsov-Ogievskiy (19): iotests.py: img_info_log(): rename imgopts argument iotests.py: qemu_img*("create"): support IMGOPTS='compression_type=zstd' iotests: drop qemu_img_verbose() helper iotests.py: rewrite default luks support in qemu_img iotest 303: explicit compression type iotest 065: explicit compression type iotests.py: filter out successful output of qemu-img create iotests.py: filter compression type out iotest 302: use img_info_log() helper qcow2: simple case support for downgrading of qcow2 images with zstd iotests/common.rc: introduce _qcow2_dump_header helper iotests: massive use _qcow2_dump_header iotest 39: use _qcow2_dump_header iotests: bash tests: filter compression type iotests 60: more accurate set dirty bit in qcow2 header iotest 214: explicit compression type iotests: declare lack of support for compresion_type in IMGOPTS iotests.py: implement unsupported_imgopts iotests: specify some unsupported_imgopts for python iotests block/qcow2.c | 58 ++++++++++- tests/qemu-iotests/031 | 11 ++- tests/qemu-iotests/036 | 6 +- tests/qemu-iotests/039 | 22 ++--- tests/qemu-iotests/044 | 8 +- tests/qemu-iotests/044.out | 1 + tests/qemu-iotests/051 | 5 +- tests/qemu-iotests/060 | 22 ++--- tests/qemu-iotests/060.out | 2 +- tests/qemu-iotests/061 | 42 ++++---- tests/qemu-iotests/061.out | 12 +-- tests/qemu-iotests/065 | 19 ++-- tests/qemu-iotests/082.out | 14 +-- tests/qemu-iotests/112 | 3 +- tests/qemu-iotests/137 | 2 +- tests/qemu-iotests/149.out | 21 ---- tests/qemu-iotests/163 | 3 +- tests/qemu-iotests/165 | 3 +- tests/qemu-iotests/196 | 3 +- tests/qemu-iotests/198.out | 4 +- tests/qemu-iotests/206.out | 10 +- tests/qemu-iotests/209 | 7 +- tests/qemu-iotests/209.out | 2 + tests/qemu-iotests/210 | 8 +- tests/qemu-iotests/214 | 2 +- tests/qemu-iotests/237.out | 3 - tests/qemu-iotests/242 | 3 +- tests/qemu-iotests/242.out | 10 +- tests/qemu-iotests/246 | 3 +- tests/qemu-iotests/254 | 3 +- tests/qemu-iotests/255.out | 4 - tests/qemu-iotests/260 | 4 +- tests/qemu-iotests/274 | 3 +- tests/qemu-iotests/274.out | 39 +------- tests/qemu-iotests/280.out | 1 - tests/qemu-iotests/281 | 3 +- tests/qemu-iotests/287 | 8 +- tests/qemu-iotests/290 | 2 +- tests/qemu-iotests/296.out | 10 +- tests/qemu-iotests/302 | 4 +- tests/qemu-iotests/302.out | 7 +- tests/qemu-iotests/303 | 26 +++-- tests/qemu-iotests/303.out | 30 +++++- tests/qemu-iotests/common.filter | 8 ++ tests/qemu-iotests/common.rc | 22 +++++ tests/qemu-iotests/iotests.py | 99 +++++++++++++------ .../tests/migrate-bitmaps-postcopy-test | 3 +- tests/qemu-iotests/tests/migrate-bitmaps-test | 3 +- .../qemu-iotests/tests/migrate-during-backup | 3 +- .../tests/remove-bitmap-from-backing | 3 +- 50 files changed, 358 insertions(+), 236 deletions(-) -- 2.31.1
