[ZODB-Dev] ZEO trace info

[Jeremy Hylton]

The current distinction between trace and debug in ZEO is that the
trace messages capture the lowest layer of the zrpc protocol.  When
you turn on trace debugging, you get log messages for each message
sent and received.  The debug level messages, in turn, talk about the
methods that are invoked as a result of those methods calls.  I'd be
opposed to a change that collapsed those two levels of logging
together.
