[Zope-Checkins] CVS: ZODB3/ZEO/tests - InvalidationTests.py:1.10

[Tim Peters]

Update of /cvs-repository/ZODB3/ZEO/tests
In directory cvs.zope.org:/tmp/cvs-serv8025/ZEO/tests

Modified Files:
	InvalidationTests.py 
Log Message:
Various:  When we opened a new connection before checking BTrees, we also
created the possibility that the checking code would need to try to read
up data from a closed connection.  This turned out to be a frequent source
of new failures in checkConcurrentUpdates1Storage (both FileStorage and BDB
flavors).  Changed all of the relevant tests to grab the BTree anew from
the newly-opened connection.
