[ZODB-Dev] UndoSearch Timeout

[Brian Brinegar]

Hello,

We have a ZODB which is about 12 - 14 gigs when packed. We use 
FileStorage, and when anyone clicks Undo eventually times out. This is 
better now that the undoLog does not lock the database.

However if there are not enough transactions to fill the batch Undo is 
useless. So, everytime we upgrade to a new version of Zope I patch 
FileStorage.py to add a timeout. Used to be 3 seconds when the ZODB 
locked, now I've bumped it up to 10 seconds.

Has anyone else had this problem? Would adding the timeout, possibly set 
by an environment variable, be considered by the maintainers?

Thanks,
