Hi all, Back in 2021, I amended the xfs create-a-filesystem helper code to support the generation of compressed metadumps. Unfortunately, I neglected to submit the other half of that code which detects a *compressed* metadump file and uses it, which means that the metadump caching used by all the xfs fuzz tests have been broken ever since, but only if DUMP_COMPRESSOR is set by the user. Fast-forward to 2022, and I noticed that fuzz tests runs would occasionally complain about POPULATE_METADUMP not pointing to a valid file if DUMP_COMPRESSOR is set, and no dump file exists, compressed or uncompressed. After some curious looks from Zorro, I finally realized that POPULATE_METADUMP points to the uncompressed file, so checking for its existence is not correct. Hence port all the code that fixed mdrestore of compressed metadumps further down the patch stack, and fix the broken conditional to get things running again. This is an extraordinary way to destroy everything. Enjoy! Comments and questions are, as always, welcome. --D --- common/ext4 | 21 +++++++++++++++++++++ common/fuzzy | 5 ++--- common/populate | 15 ++------------- common/xfs | 29 +++++++++++++++++++++++++++++ tests/xfs/129 | 2 +- tests/xfs/234 | 2 +- tests/xfs/253 | 2 +- tests/xfs/284 | 2 +- tests/xfs/291 | 2 +- tests/xfs/336 | 2 +- tests/xfs/432 | 2 +- tests/xfs/503 | 8 ++++---- 12 files changed, 65 insertions(+), 27 deletions(-)
