Re: [Maria-developers] How handle_rpl_parallel_thread rollback partial transaction when STOP SLAVE In parallel replication

Kristian Nielsen <knielsen@knielsen-hq.org> writes:

The idea to fix this isas follows:

- We record which transactions have started to commit

- When we do STOP SLAVE we remember the transaction that last started to commit at the point at which we stopped.

- In handle_rpl_parallel_thread(), we only start skipping events from transactions that start strictly _after_ the stop point. Prior transactions have no events skipped.

I put my current patch here:

Hm, that patch is not sufficient, the bug is still there :-( Sorry about that. At least I did say that the patch was incomplete. I will fix it properly and let you know when I have something new. - Kristian.
