Assertion `!log->same_pk' failed in row_log_table_apply_delete





      • it can be related to MDEV-14837, or even be a direct consequence of it. If so, please feel free to close as a duplicate.
      • Please note that you (probably) need to apply the attached/pasted patch mtr_default_server.patch to MTR, and run the test case with --default-server-options. The patch doesn't do any dirty tricks, it simply makes MTR to bootstrap and run the server with real default server options. On some reason, I couldn't reproduce it otherwise, even by restoring all options changed by MTR to their true default values on the command line. Possibly it has something to do with how the server bootstraps, but I couldn't positively confirm it. In any case, I expect that the reason will become apparent when the cause of the failure is known.
      • Even with the MTR patch, the test case is highly non-deterministic and mustn't be put into the regression suite. The current test case runs 50 loops inside it (so there is no need to run with --repeat). On my machine it has always failed withing first 20 loops, but I assume it can vary.
      • It fails for me on an ASAN build, too.
