[Twisted-Python] Twisted Project Jobs Volunteer
by Adi Roiban Nov. 17, 2011

Nov. 17, 2011

Hi, I have been using Twisted for about 6 months and looking for ways in which I could help the project. I just read the announcement and I would like to volunteer for one of the Twisted jobs. I am familiar with bzr and git and for the beginning I would like to start with maintaining the version control mirrors (bzr and git) and if this will not consume all my free time, I would also like to take care of buildbot master and slaves (or some other job that you consider is more important). Beside the job description, I was thinking that creating repositories mirrors on Github/Gitorious could be useful. The Launchpad BZR mirror seems to be functional. Hoping that I can be useful, please let know if my application is accepted. Cheers, -- Adi Roiban

[Twisted-Python] Boston Twisted Sprint: November Edition
by Tenth Nov. 9, 2011

Nov. 9, 2011

In an attempt to get back into the habit of holding Monthly sprints planned somewhat more in advance, I'm pleased to announce that we'll be hosting another Twisted Sprint at the Smarterer offices on Sunday, November 13th, from about 1:00 to 9:00 PM. If you'd like to attend but aren't on the contact list, let me know! We prefer that sprinters RSVP for food planning purposes (and to receive more detailed instructions about getting into the building, which is locked down on weekends). Thanks, - Dave

[Twisted-Python] Docs HTML suggestion/request for moving between versions.
by Phil Mayers Nov. 6, 2011

Nov. 6, 2011

Lately, I've taken to finding Twisted docs by writing: twisted.internet.task.Cooperator ...into the Chrome bar'o'magic and hitting return to get the Google hit. This is great, except that the resultant Google hits almost always point me to the 8.2.0 HTML docs. 2nd hit is (currently) 11.0 docs. Obviously it's tricky to force Google to put "current" at the top! But could we maybe have a little <select> dropdown in the top-right that shows the version, and lets you pick a new one and have the page reload? It strikes me that this would be useful in general, for flicking back and forward between two versions of the docs page for a given method/API.

[Twisted-Python] Ideas on limiting/throttling spawnProcess
by Daryl Herzmann Oct. 31, 2011

Oct. 31, 2011

Hi, I have an application that ingests data and does a reactor.spawnProcess() for each chunk of data (a product) to pass it as STDIN to a compiled binary and then I harvest the STDOUT. It has been working well, but I have an issue when my data rates get too high and the machine gets overloaded with spawned processes (I think) and starts running out of file descriptors (yes I can raise it :) causing all sorts of pain. I'm wondering about a mechanism to throttle the number of spawned processes going at one time? It'd be nice to only have 10 of these spawned processes going at any one time. Thanks for your ideas :) daryl code snipet: class SHEFIT(protocol.ProcessProtocol): def __init__(self, tp): self.tp = tp self.data = "" def connectionMade(self): self.transport.write( self.tp.raw ) self.transport.closeStdin() def outReceived(self, data): self.data = self.data + data def errReceived(self, data): print "errReceived! with %d bytes!" % len(data) print data def outConnectionLost(self): really_process(self.tp, self.data) def got_product(): shef = SHEFIT( tp ) reactor.spawnProcess(shef, "shefit", ["shefit"], {}) def really_process(tp,data): print 'Do some work'

[Twisted-Python] [ANN] Pyflakes 0.5.0
by Tristan Seligmann Oct. 31, 2011

Oct. 31, 2011

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 It is my unexpected pleasure to announce the release of Pyflakes 0.5.0, the first release in several years, and available now from PyPI[1]. Highlights of this release include the use of the built-in AST instead of the compiler module, and support for various new syntax constructs in Python 2.7. Note that development of Pyflakes (as well as the other divmod.org projects) has moved to Launchpad[2] since the last release.

[Twisted-Python] Moving tickets forward
by Itamar Turner-Trauring Oct. 29, 2011

Oct. 29, 2011

Ticket #3690 was filed as "serial ports do not call connectionLost on their protocol", but along the way became a ticket for testing *all* of the serial port code. Since the latter is much harder, it got stuck in addressing review comments, and the simpler original problem was not fixed. In this case, the perfect was the enemy of the good. To prevent this sort of thing, if you end up enlarging the scope of a ticket dramatically, please open a new ticket and divide the work up. Splitting up large amounts of work into smaller units is good even if the scope of the ticket hasn't changed. Smaller units of work are easier on everyone, developers and reviewers; please look for opportunities to break up tickets into multiple smaller tickets if that will help get code merged.

[Twisted-Python] Status of the Bazaar mirror
by exarkun＠twistedmatrix.com Oct. 27, 2011

Oct. 27, 2011

Hello committers, There's a new svn post-commit hook that should keep the bzr mirror up to date. It might slow down commits a little bit, maybe by 10 seconds or so. You can find the bzr mirror at <http://svn.twistedmatrix.com/svn/Twisted> (/trunk, /branches/halfclose- tls-5341, etc). Let me know if you notice any problems with it. Thanks to Adi Roiban for writing the scripts to keep the mirror up to date and to James Knight for pointing out flock(1) as a way to avoid problems with concurrency. Jean-Paul

[Twisted-Python] First pre-release of Twisted 11.1.0
by Thomas Hervé Oct. 26, 2011

Oct. 26, 2011

Hello, fine people of the intraweb, We're dangerously approaching the end of the year, without a second release done, which is obviously unacceptable. I thus present you with Twisted 11.1.0pre1: http://people.canonical.com/~therve/Twisted/11.1.0pre1/ Some hightlights of the 178 tickets closed: * The poll reactor as default where applicable, instead of select everywhere. * A new SSL implementation only relying on OpenSSL for cryptography, (not I/O) making it more robust, and adding IOCP support in the process. * Several improvements to the fresh HTTP/1.1 client implementation, including proxy and cookie support. * My personal favorite: a new howto has been published on test-driven development with Twisted. * A special mention to the new abortConnection support on TCP and SSL connections, heroically pushed by Itamar and Jean-Paul, and the oldest ticket closed by this release. Please give it all the testing love it deserves (and be harsh if necessary). Release-manager-ly yours, -- Thomas
