Python - Killing an active Thrift call
Hi,
Is it possible to kill an active/open request in Python?
I have locking code around a thrift call, but sometimes the other side
(server) doesn't return (not in my control). I would like to force that
connection to close so that the thread can continue on.
I've tried to close the transport, thinking it would fail out, but no luck.
Thanks.

I asked a question like this awhile ago on this list. I was told that Thrift does not have a way to interrupt an ongoing RPC from the client. In the past I have done this by interrupting the thread that was making the call (this was in Java), but this is probably not quite right as I imagine it leaves the server spinning.

Quite

The Python TSocket class has a setTimeout method which IIUC is your best
bet for somewhere to bail on a call.
It raises some kind of exception IIRC (possibly socket.timeout, although
this would be trivial to check).
Example code here:

I don't know that there's a built-in facility for this, but it sounds like
what timeouts are often used for. How are you receiving the info that the
other side won't return? Can you use timeouts on the thrift client sockets
for this?
