By Mark's patches you mean the patches that I push to the public. We now have several people hacking on MySQL besides me. Ben Handy does the InnoDB SMP changes. I am trying to get Ben, Gene (show user_stats), Justin (replication), Yuan (MySQL to Bigtable/Hadoop/... replication) and Nick to submit proposals to the MySQL Conference. Some of the work in progress might be interesting to others. We have implemented binlog event checksums, global transaction IDs and a few bug fixes that make slave replication state crash proof. We want to extend the use of internal XA transactions to keep the SQL slave thread and storage engines in sync as an alternative to our current use hidden variables in the InnoDB tx log. We have many more SMP changes in progress but none are stable enough to share. Where in the land of drizzle branches is the change to clean up the net send/receive code so it uses blocking calls with timeouts rather than setsockopt(non blocking), try call, setsockopt(blocking), request a timeout alarm from another thread, do blocking call, ...? If you have it, I want to copy it. > > Cheers, > -Brian > > -- > _______________________________________________________ > Brian "Krow" Aker, brian at tangent.org > Seattle, Washington > http://krow.net/ <-- Me > http://tangent.org/ <-- Software > _______________________________________________________ > You can't grep a dead tree. > > > > -- Mark Callaghan [EMAIL PROTECTED] _______________________________________________ Mailing list: https://launchpad.net/~drizzle-discuss Post to : [email protected] Unsubscribe : https://launchpad.net/~drizzle-discuss More help : https://help.launchpad.net/ListHelp
