[Twisted-Python] Buildbot downtime
by Tom Prince 03 Mar '22

03 Mar '22

I am plannig to upgrade twisted's buildbot in the near future. In preperation for that, I am going to take down the production buildbot on Tuesday, June 26, around 1600 UTC[1]. During that time, the result of any builds done will be lost. Thus, I'd ask that people avoid committing to trunk during that time. I will send a reminder before I take down the buildbot both here, and on #twisted and #twisted-dev. Tom [1] http://timeanddate.com/worldclock/meetingtime.html?iso=20120626&p1=80&p2=22…

[Twisted-Python] Twisted Python 0.7.0 Prerelease Testing
by Glyph Lefkowitz 05 Aug '21

05 Aug '21

hi there, folks: I'd really like to release 0.7.0 but I would like it to be at least a little bit tested before I do so. Could those of you with CVS trees check everything out and see if it performs as advertised? Deeper bugs than that will have to wait for the next release, but I'd at least like to know if it works for someone other than me. Thanks. ______ __ __ _____ _ _ | ____ | \_/ |_____] |_____| |_____| |_____ | | | | @ t w i s t e d m a t r i x . c o m http://www.twistedmatrix.com/~glyph/

[Twisted-Python] Twisted tips for designing highly concurrent twisted REST API
by Waqar Khan 14 Jul '19

14 Jul '19

Hello folks, I recently stumbled upon twisted and was wondering if it could suit my needs. On one hand, I want to use python but on another hand there are all these scalability concerns with this language so, I though I would pick the brains of the community. So.. a flask based app would look something like this. similar_types = ['foo', 'bar', 'baz'] def long_computation(rec_type): # some long computation return recs @app.route('/fetch_similar_users/<user_id>' def fetch_similar_users(user_id) r = json.loads(requests.get('url/to/fetch/%s'%user_id).text) recs = {} for stype in similar_types: recs[stype] = long_computation(rec_type) return recs Now, I tried to "twistify" but it failed. @defer.inlinecallbacks def long_computation(rec_type): # some long computation *defer.returnValue(recs)* @defer.inlinecallbacks def fetch_data(user_id): r = yieldjson.loads(requests.get('url/to/fetch/%s'%user_id).text) defer.returnValue(r) @defer.inlinecallbacks def fetch_recs(user_id): data = yield fetch_data(user_id) recs = {} for stype in similar_types: d = defer.ToThread(fetch_data, *(stype)) rec = yield d recs[stype] = rec defer.returnValue(recs) I wrapped all the above in twisted render_Get method.. but then I did a load test with locust (https://docs.locust.io/en/latest/what-is-locust.html) framework. It choked. As the time progressed, the response time increased. I am guessing, things are still blocking. Can you please help me look into the right place. Why exactly am I seeing increase in response time as the time progresses. I am guessing things are still working in "blocking" fashion but i thought the above should run things in async. Thanks

[Twisted-Python] some logging thoughts
by Glyph 12 Jul '19

12 Jul '19

L. Daniel Burr and I got up to some interesting reflections on Twisted's logging system in this Ampoule PR: https://github.com/twisted/ampoule/pull/29/files/268e4dcd8072d37780fd7ff0d8… <https://github.com/twisted/ampoule/pull/29/files/268e4dcd8072d37780fd7ff0d8…> This discussion may be of some general interest to folks on this list. (Also, this is a good opportunity to remind anybody who is looking for small ways to improve Twisted that porting things from twisted.python.log to twisted.logger is generaly a net win :)) -glyph
