[Twisted-Python] any progress for Ticket #6346, #6378?
Hi All I am quite concerned about these two tickets due to recently I may port one of my systems to Ubuntu. By reading these comments, It looks like recent version of twisted may suffer from this problem. So what version of twisted should I use? Do I need to keep using 10.1? I always use the latest version on windows. Regards gelin yan

Hi Gelin, I don't have anything extra to add about the status of those two tickets (I think you meant #6373 rather than #6378, by the way) - which is exactly why I'm replying. Twisted development doesn't take place in secret. The issue tracker should always reflect the latest state of the development process. If an issue has had no comments and a branch no commits for a couple months, then it's almost certainly because no one has worked on the issue for a couple months. So you generally don't need to ask if there has been any progress, because progress will always be reflected in ticket history or in version control.

Perhaps you can help out with the tickets, then! As hopefully you've noticed, one of them is currently up for review. This means a developer believes a fix for the problem has been created and is just waiting for someone else to look it over and agree that it should be applied to trunk. If this happens, then the fix will be available in the next release of Twisted, 13.1.0, which will probably happen in just a few weeks.

Hi exarkun I noticed "review" tag has been removed for a while so does it imply this ticket is still pending? I am not quite familiar how epoll works on linux so my help probably can be neglected. I event can't sure how to reproduce this bug. By the way, Is it possible to use the "old" epoll implementation instead of the built in epoll from python with the latest version? It looks like this old one works quite well. Thanks Regards gelin yan

This problem is very frequent on Linux with Python 2.7 / Twisted 12
combination (we had to quickly roll back- cannot operate with that combo).
It never happened with Python 2.6 / Twisted 10 (as in years).
It happens very infrequently with Python 2.7 / Twisted 10.1 (as 1x in weeks)
Right now I have a server in this state on Python 2.7 / Twisted 10.1. It
refuses 30% of new connections, spewing this error:

If I restart the server, it will be stable for a couple of weeks, until some
event triggers this problem again. We hope that this problem is fixed before
we are really forced to migrate to newer Python, otherwise there's no real
upgrade path for us using Twisted.

A workaround for the problem is available on a branch for https://twistedmatrix.com/trac/ticket/6373. The remaining work is fairly trivial, I just haven't gotten around to it due to lack of free time. If you're interested you should (a) test the fix and (b) perhaps submit a patch that addresses the remaining review tickets. -Itamar

http://twistedmatrix.com/cgi-bin/mailman/listinfo/twisted-python Hi Itamar
I will give it a try without guarantee due to I am not quite familiar
with epoll itself :)
