Debug build, -DEXTRA_DEBUG
Description
parts.partition_debug fails with 2 warnings "Table: ./test/t1#P#p2 is open on rename new table2"
This happens only in 10.7 (I could not repeat it with 10.6) when compiled with DBUG
I can repeat it to 100% on my desktop.
parts.partition_debug [ fail ] Found warnings/errors in server log file!
Test ended at 2022-01-24 15:59:58
line
Warning: Table: ./test/t1#P#p2 is open on rename new table2
Warning: Table: ./test/t1#P#p2 is open on rename new table2
A shorter test case, just for debugging:
(The normal test case, parts.partition_debug only needs to be extended with this MDEV number). Note that it is the new code for CONVERT PARTITION that is generating the issue.
As a separate issue, I noticed that the code does try to rename files that does not exists:
error: error: 7 message: 'Error on rename of './test/tp2.MYD' to './test/t1#P#p2.MYD' (Errcode: 2 "No such file or directory")
That code could probably be cleaned up so that we don't generate errors/warnings that are not needed (for example by testing if the file exists or not before doing a rename)
