test case (to be run locally)

Not sure if it's a SocketStreamHandleCFNet or pywebsocket issue, but I couldn't open more than a few dozen connections to a local WebSocket server.

Please see attached test case. I'm getting results as low as 25 or as high as 89 randomly.

I want to have at least some large number guaranteed to make a test verifying that WebSocket is not subject to HTTP connection limit (currently 4 or 6 in different implementations, but it would be best to set a much higher threshold in the test).

r=me. The patch doesn't include a test case - would be nice to land the attached one at the same time.

This is the cause?
2010-01-18 13:25:39.906 DumpRenderTree_debug.exe[2688:994] *** More than MAXIMUM_WAIT_OBJECTS (64) ports add to a port set.  The last ones will be ignored.

Comment 10 Alexey Proskuryakov 2010-01-19 08:25:23 PST
Sounds like that!

64 is enough for my purposes - changed the test to only make 50 connections.
