Since Testy is still not a mature framework, this could be a false positive but it deserves investigation to make sure.
To get to the artifacts and check the mismatch using testy:
fab launch-snapshot --snapshot-id=snap-09aac2847e7c4d77f # Log to the newly created host cd /srv/testy/ export PYTHONPATH=/srv/testy/wiredtiger/build/lang/python:/srv/testy/wiredtiger/tools:$PYTHONPATH sudo -HE env PATH=$PATH PYTHONPATH=$PYTHONPATH python3 wiredtiger/tools/wt_cmp_uri.py data/table:table_XPox8 data/table:table_XPox8_mirror
This should give you the following output:
for key=0000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000, value is different: data/table:table_XPox8: ouVuX8oX1HUCmBc1m9ZfY5tTJq0sxxQpQFAwzOAAzxPtS0xSseFSScU8vBWa26qT6ZqrHFRpoXK4b8aPEXyOwC22aUuRw3M6HQw3..., data/table:table_XPox8_mirror: U5LKTgNCfyzAI08Ge4bfAtYxMV9NssY81hcc0g7R05ZYJFA2C8ChtGpPVeoJWmTLcn7CWJiMtk7txCAd4cvXFwfKM4T297YSvIgg... 48 records read
The two values for that key are marked as value/ovfl.
Some context about how Testy works:
- A workgen workload runs continuously
- Snapshots of the instance are taken periodically, this means we the database is very likely to have unstable data at the time of the snapshot
- We run recovery on the database and verify using the wt utility tool
- We execute the validate_mirror_tables.py script to validate the mirrors - this is where the mismatch is discovered
