> I have my own CouchDB driver for Tornado Asynchronous web framework called Trombi[1]. It's basically just a wrapper around HTTP calls to CouchDB, making them play nicely with the asynchronous nature of Tornado (unlike other Python CouchDB libraries). I've made a test[2] that opens up longpolling changes feed and writes a document in database and then waits to receive the same document via changes feed listener. What happens is that the changes feed listener never gets the reply or if it gets one, it is empty (ie. rows: []).
> Problem is not my library, Tornado or the underlying HTTP client (pycurl or pure-python implementation provided by Tornado). I can verify with tcpdump/tcpflow that CouchDB responds with empty changes feed result after the timeout. Tests pass on my Ubuntu computer.
> Steps to reproduce:
> 1) Clone Trombi[1]
> 2) Install tornado, pycurl and nose from PyPI using easy_install/pip
> 3) Run tests, nosetests -v. Should stall on the test mentioned [2]
> I've also posted about this on mailing list[3], but figured out it might be a better thing to create a ticket
