    "content": "Original (very broken) v1 posting:\n\n  https://lists.nongnu.org/archive/html/qemu-devel/2025-10/msg01650.html\n\nThe recent set of regressions identified in the LUKS block driver\nre-inforced that despite having a hugely useful set of I/O tests,\nour CI coverage is still letting through too many bugs.\n\nThe core goals of this series were/are:\n\n * Add LUKS and NBD to the tested formats/protocols\n   integrated into \"make check-block SPEED=thorough\"\n\n * Ensure that all qcow2 tests can be run with \"SPEED=slow\",\n   not staying limited to only the 'auto' group used by the\n   'make check-block' target in its default 'quick' mode\n\n * Add  'make check-block-$FORMAT' to expose a standalone\n   target for running all tests for a given format (or\n   equivalently a protocol)\n\n * Add GitLab CI jobs for exercising tests for all formats\n\nA sample pipeline for this is\n\n  https://gitlab.com/berrange/qemu/-/pipelines/2258731804/\n\nShowing the 'block-FORMAT-centos' jobs which test the 10\nblock formats/protocols currently enabled.\n\nThis series fixes a couple of bugs\n\n * sendmsg generates a deprecation warning on centos\n\n * Test 128 check for device mapper usage doesn't work\n   sufficiently well to detect gitlab's containe env\n   can't do dynamic devfs\n\n * Test 185 is reliably failing on gitlab\n\nI'm unclear if there are other non-deterministic failures that\nwould only appear if we start running the tests regularly, or\nagainst QEMU's private runners instead of gitlab shared runners.\n\nThe ones I've fixed have been consistent across quite a few test\npipelines so far with the shared runners.\n\nAt this point it is a chicken & egg problem though.\n\nIf we don't bite the bullet and enable block I/O tests in GitLab\nwe'll never find out if they're stable enough to rely on.\n\nAs a mitigation against instability a patch in this series adds\na QEMU_TEST_IO_SKIP env variable that we are able to set as a\nGitLab CI env variable. This lets us skip broken tests without\nwaiting for a git commit to disable them.\n\nChanged in v4:\n\n  - Remove tests from build-tcg-disabled job\n\nChanged in v3:\n\n  - Test whether dmsetup create device appeared or not, instead\n    of unconditionally skipping test 128 in GitLab\n  - Use 'driver' term instead of 'format' or 'protocol'\n  - Fix misc typos & rephrasing\n\nDaniel P. Berrangé (15):\n  Revert \"python/aqmp: fix send_fd_scm for python 3.6.x\"\n  tests: print reason when I/O test is skipped in TAP mode\n  tests: remove redundant meson suite for iotests\n  tests: ensure all qcow2 I/O tests are able to be run via make\n  scripts/mtest2make: ensure output has stable sorting\n  scripts/mtest2make: support optional tests grouping\n  tests: add a meson suite / make target per block I/O tests format\n  docs/devel/testing: expand documentation for 'make check-block'\n  tests: add nbd and luks to the I/O test suites\n  tests: use 'driver' as collective term for either format or protocol\n  tests: validate dmsetup result in test 128\n  tests: fix check for sudo access in LUKS I/O test\n  tests: add QEMU_TEST_IO_SKIP for skipping I/O tests\n  gitlab: add jobs for thorough block tests\n  gitlab: remove I/O tests from build-tcg-disabled job\n\n .gitlab-ci.d/buildtest.yml       | 101 ++++++++++++++++++++++++++++---\n docs/devel/testing/main.rst      |  33 +++++++++-\n python/qemu/qmp/qmp_client.py    |   9 +--\n scripts/mtest2make.py            |  30 ++++++---\n tests/Makefile.include           |   3 +-\n tests/qemu-iotests/128           |   6 ++\n tests/qemu-iotests/149           |  13 ++--\n tests/qemu-iotests/meson.build   |  59 +++++++++++++++---\n tests/qemu-iotests/testrunner.py |  18 +++++-\n 9 files changed, 229 insertions(+), 43 deletions(-)"
