---------------------------------
Component/s: Wish List
> Unify exception handling policy of TProcessor
> ---------------------------------------------
>
> Key: THRIFT-3607
> URL: https://issues.apache.org/jira/browse/THRIFT-3607
> Project: Thrift
> Issue Type: Improvement
> Components: Wish List
> Reporter: Aki Sukegawa
>
> A discussion in THRIFT-1805 uncovered inconsistent error handling behaviors
> of TProcessors across languages and releases.
> Most outstanding are Java sync and async processors as described there, but
> others are also subtly different in details.
> I propose unifying the TProcessor behavior by specifying mappings from
> "uncaught server handler exceptions" to "observable server behaviors" as
> follows:
> * TApplicationException -> send TApplicationException with the message and
> the type as thrown
> * TTransportException -> the connection is either already broken or newly
> broken
> * other exceptions -> send opaque TApplicationException(INTERNAL_ERROR)
> That way users can still arbitrarily disconnect the client by throwing
> TTransportException.
> (IMO ideally this should have been done by exposing "client context" object
> to the handler instead)
> The first one can be a bit controversial as it can be regarded as information
> leak.
> Also some may prefer unifying the TProcessor behavior to catch-all, so that
> servers never die on handler exceptions.
