Henry Robinson commented on ZOOKEEPER-510:

I should mention that the segfault issue is already reported at ZOOKEEPER-540 - 
this patch should fix that issue and this one.

> The current zkpython bindings always throw "IOError("text")" exceptions, even 
> for ZK specific exceptions such as NODEEXISTS. This makes it difficult (error 
> prone) to handle exceptions in python code. You can't easily pickup a 
> connection loss vs a node exists for example. Of course you could match the 
> error string, but this seems like a bad idea imo.
> We need to add specific exception types to the python binding that map 
> directly to KeeperException/java types. It would also be useful to include 
> the information provided by the KeeperException (like path in some cases), 
> etc... as part of the error thrown to the python code. Would probably be a 
> good idea to stay as close to java api as possible wrt mapping the errors.
