For the "commit" command, this is relatively easy, so implement it first (in the hope that indeed others will follow). As qemu-img does not have access to QMP (due to QMP being intertwined with basically everything in qemu), we cannot directly use QMP, but at least use the functions the corresponding QMP commands are using (which would be "block-commit", in this case). v11: - Rebased on Kevin's block branch git-backport-diff output against v10: Key: [----] : patches are identical [####] : number of functional differences between upstream/downstream patch [down] : patch is downstream-only The flags [FC] indicate (F)unctional and (C)ontextual differences, respectively 001/14:[----] [--] 'qcow2: Allow "full" discard' 002/14:[----] [--] 'qcow2: Implement bdrv_make_empty()' 003/14:[----] [--] 'qcow2: Optimize bdrv_make_empty()' 004/14:[----] [--] 'blockjob: Introduce block_job_complete_sync()' 005/14:[----] [--] 'blockjob: Add "ready" field' 006/14:[----] [-C] 'block/mirror: Improve progress report' 007/14:[----] [--] 'qemu-img: Implement commit like QMP' 008/14:[----] [--] 'qemu-img: Empty image after commit' 009/14:[----] [--] 'qemu-img: Enable progress output for commit' 010/14:[----] [--] 'qemu-img: Specify backing file for commit' 011/14:[----] [-C] 'iotests: Add _filter_qemu_img_map' 012/14:[----] [-C] 'iotests: Add test for backing-chain commits' 013/14:[----] [-C] 'iotests: Add test for qcow2's bdrv_make_empty' 014/14:[----] [--] 'iotests: Omit length/offset test in 040 and 041' Max Reitz (14): qcow2: Allow "full" discard qcow2: Implement bdrv_make_empty() qcow2: Optimize bdrv_make_empty() blockjob: Introduce block_job_complete_sync() blockjob: Add "ready" field block/mirror: Improve progress report qemu-img: Implement commit like QMP qemu-img: Empty image after commit qemu-img: Enable progress output for commit qemu-img: Specify backing file for commit iotests: Add _filter_qemu_img_map iotests: Add test for backing-chain commits iotests: Add test for qcow2's bdrv_make_empty iotests: Omit length/offset test in 040 and 041 block/Makefile.objs | 2 +- block/mirror.c | 34 ++-- block/qcow2-cluster.c | 27 ++- block/qcow2-snapshot.c | 2 +- block/qcow2.c | 388 ++++++++++++++++++++++++++++++++++++++- block/qcow2.h | 2 +- blockjob.c | 42 ++++- include/block/blockjob.h | 20 ++ qapi/block-core.json | 4 +- qemu-img-cmds.hx | 4 +- qemu-img.c | 149 ++++++++++++--- qemu-img.texi | 13 +- tests/qemu-iotests/040 | 4 +- tests/qemu-iotests/041 | 3 +- tests/qemu-iotests/097 | 122 ++++++++++++ tests/qemu-iotests/097.out | 119 ++++++++++++ tests/qemu-iotests/098 | 75 ++++++++ tests/qemu-iotests/098.out | 26 +++ tests/qemu-iotests/common.filter | 7 + tests/qemu-iotests/group | 2 + tests/qemu-iotests/iotests.py | 3 +- 21 files changed, 981 insertions(+), 67 deletions(-) create mode 100755 tests/qemu-iotests/097 create mode 100644 tests/qemu-iotests/097.out create mode 100755 tests/qemu-iotests/098 create mode 100644 tests/qemu-iotests/098.out -- 2.0.4
