Jyrki Pulliainen reopened COUCHDB-1105:
---------------------------------------
Skill Level: Regular Contributors Level (Easy to Medium)
After running more tests, it still seems to fail every now and then, at about
50% rate. However, that is an improvement to the previous state, where the
failing rate was 100%.
> Longpoll changes does not always work on OS X

> 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
