[Zope-Checkins] CVS: Packages/ZODB - FileStorage.py:1.135.6.6

Update of /cvs-repository/Packages/ZODB
In directory cvs.zope.org:/tmp/cvs-serv12383/ZODB

Modified Files:
      Tag: Zope-2_7-branch
	FileStorage.py 
Log Message:
Collector 1327:  FileStorage init confused by time travel

If the system clock moved back in time more than 30 days between
a FileStorage close and (re)open, new txn ids could be smaller
than txn ids already in the database.  Plugged that hole.

Includes a stripped-down rewrite of the new test in ZODB 3.3.  Main
difference is that this version doesn't automatically check that new
log messages are actually produced; that's easier to do in 3.3,
building on an extension to the logging package Jim wrote for Zope 3.
