Description Radim Vansa 2013-11-04 08:49:15 UTC

Situation with optimistic TX, originator = entry's primary owner:

1. The conditional check suceeds when the command is executed
2. In TxDistributionInterceptor, ignorePreviousValue is set to true
3. The command is then enlisted in the modifications list with the ignorePreviousValue set to true
4. During the prepare/commit phase the command ignores the condition

Result:
Two commands, replace(key, A, B), replace(key, A, C) may both overwrite the entry (and the one committed later wins, actually overwriting B instead of A).
