Since blkhash is available only via copr now, the new command is added as optional feature, built only if blkhash-devel package is installed.
Changes since v1 (Hanna): - Move IO_BUF_SIZE to top of the file - Extend TestFinder to support format or cache specific out files - Improve online help (note about optimization and lint to blkhash project) - Guard blkhash.h include with CONFIG_BLKHASH - Using user_creatable_process_cmdline() instead of user_creatable_add_from_str() - Rename ret to exit_code - Add static assert to ensure that read buffer is algined to block size - Drop unneeded pnum variable - Change test to work like other tests; use iotest.imgfmt and iotest.cachemode - Simplify test to test only raw and qcow2 format using file protocol - Fix code style issues (multi-line comments, missing braces) - Make error checking more clear (checksum_block_status(s) < 0) v1: https://lists.nongnu.org/archive/html/qemu-block/2022-09/msg00021.html v1 discussion: - https://lists.nongnu.org/archive/html/qemu-block/2022-10/msg00602.html - https://lists.nongnu.org/archive/html/qemu-block/2022-10/msg00603.html - https://lists.nongnu.org/archive/html/qemu-block/2022-10/msg00604.html - https://lists.nongnu.org/archive/html/qemu-block/2022-11/msg00171.html - https://lists.nongnu.org/archive/html/qemu-block/2022-11/msg00173.html Nir Soffer (5): qemu-img.c: Move IO_BUF_SIZE to the top of the file Support format or cache specific out file qemu-img: Add checksum command iotests: Test qemu-img checksum qemu-img: Speed up checksum docs/tools/qemu-img.rst | 24 ++ meson.build | 10 +- meson_options.txt | 2 + qemu-img-cmds.hx | 8 + qemu-img.c | 390 +++++++++++++++++- tests/qemu-iotests/findtests.py | 10 +- tests/qemu-iotests/tests/qemu-img-checksum | 63 +++ .../tests/qemu-img-checksum.out.qcow2 | 11 + .../tests/qemu-img-checksum.out.raw | 10 + 9 files changed, 523 insertions(+), 5 deletions(-) create mode 100755 tests/qemu-iotests/tests/qemu-img-checksum create mode 100644 tests/qemu-iotests/tests/qemu-img-checksum.out.qcow2 create mode 100644 tests/qemu-iotests/tests/qemu-img-checksum.out.raw -- 2.38.1
