[Zodb-checkins] CVS: ZODB3/ZEO - ClientStub.py:1.10.2.1

[Jeremy Hylton]

Update of /cvs-repository/ZODB3/ZEO
In directory cvs.zope.org:/tmp/cvs-serv14016/ZEO

Modified Files:
      Tag: ZODB3-3_1-branch
	ClientStub.py 
Log Message:
Make sure invalidations are sent atomically by the ZEO server.

Extend zrpc with a way to call a method without also calling poll() to
do I/O.  The I/O is undesirable because it could allow a load from a
client to sneak in before the invalidation is sent.  The I/O is
unnecessary because the caller will return to the mainloop and do the
I/O when all the invalidations are sent.

Patch from Guido.
