Twisted Introduction
hi dave, I’m Jayson Pryde, and I’m new to twisted. I’ve been learning Twisted via your awesome tutorial, and I am already in part 13. I tried to implement my own client-server system, but I am encountering some hangs in the client. It’s probably because I messed up with callbacks in the deferred. I’ve asked this via this link in stackoverflow: http://stackoverflow.com/questions/42418021/asynchrono
Benchmarking Tornado vs. Twisted Web vs. Tornado on Twisted | Programming Zen
Benchmarking Tornado vs. Twisted Web vs. Tornado on Twisted FriendFeed, which was recently acquired by Facebook, just released an interesting piece of open source software. Tornado is an open source version of the scalable, non-blocking web server and tools that power FriendFeed. The FriendFeed application is written using a web framework that looks a bit like web.py or Google’s webapp, but with a
MySQLPlus と NeverBlock
前に Rails がマルチスレッドになっても MySQL のドライバとかがブロックしたらダメじゃないの？ という話をちらっと書いた. やっぱりダメというのが結論らしい. MySQLplus は そんな問題に対処する ruby の MySQL ドライバ拡張だというので眺めてみた. MySQL の API がブロッキングで困るだなんて, まったく他人事には思えない. MySQL ドライバの API は基本的にマルチスレッド+ブロッキングを前提とした設計をしており, 刺さりそうな場所は多い. 中でも一番困りそうなのは mysql_query() や mysql_real_query() だろう. ばしっとクエリーを投げて結果を受けとるこれらの API は, MySQL から返事が戻ってくるまでデータを待ち続ける. MySQL/Ruby もこの API を使っている. 普通に考えるとお手上げに見え

Twistedでテスト用SMTPサーバーを書く - Doge log
メールのテストとかってめんどい。 Mockとかそーいうのすらもめんどい。 もうサーバーを書いてしまった方がいいんじゃない？ってひと向け。 Twisted本持ってるひとには無用のエントリだね、そのまんまだから。 mailserver.py from twisted.mail import smtp, maildir from zope.interface import implements from twisted.internet import protocol, reactor, defer import os from email.Header import Header class MaildirMessageWriter(object): implements(smtp.IMessage) def __init__(self, user_dir): print "mailbox %
Twistedで☆をつけまくる - Doge log
何かと話題のはてなスターにTwistedでアクセス。 star.py # coding=utf-8 from twisted.internet import reactor from twisted.application.internet import TimerService from twisted.web import client from urllib import urlencode import re CONST_LOGIN = 'https://www.hatena.ne.jp/login' CONST_ADD_STAR = 'http://s.hatena.ne.jp/star.add.json?%s' const_title_re = re.compile(r'<title>([^<]*) - ([^<]*)</title>', re.M | re.I) dummy_
Genshi Templates in Nevow
Karl Bartel said... This is really interesting. I prefer Genshi templates to the nevow XML templates. But I'm using Genshi directly on top of twisted.web . Which nevow benefits are left, when you don't use its templating system? Anything except the possibility to use athena? 2:12 PM Duncan McGreggor said... Well, since I do lots of non-web Twisted and much of it can integrate with the web, I like
