Review: Approve I did not like very much the versioning solution for the collection deadlock. It certainly does not work with multi-threading. But this is not the only thing that is wrong for multi-threading, so I will approve.
I think a better solution would be that any dml:collection() function that is executed within a nonmaterialize pragma acquires the collection lock in exclussive mode. Of course that would require changes in the compiler, runtime, and store api. -- https://code.launchpad.net/~zorba-coders/zorba/bug-1026250/+merge/138044 Your team Zorba Coders is subscribed to branch lp:zorba. -- Mailing list: https://launchpad.net/~zorba-coders Post to : firstname.lastname@example.org Unsubscribe : https://launchpad.net/~zorba-coders More help : https://help.launchpad.net/ListHelp
