[Twisted-Python] Twisted Python 0.7.0 Prerelease Testing
by Glyph Lefkowitz Aug. 5, 2021

Aug. 5, 2021

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. ______ __ __ _____ _ _ | ____ | \_/ |_____] |_____| |… [View More]

[Twisted-Python] Handling of NMEA messages
by Albert Brandl Dec. 1, 2010

Dec. 1, 2010

Hi! We are working on a project that has to extract weather information from an NMEA stream. There is a NMEAReceiver class, but it only extracts GPS information - as expected, since the class is defined in t.p.gps.nmea. We intend to add the NMEA-0183 messages necessary for my purposes. The question is: should we just extend the NMEAReceiver? Weather information is not exactly what one would expect in a class below t.p.gps... On the other hand, it would be strange to create a different kind … [View More]

[Twisted-Python] Missing connections with Perspective Broker ( newbie alert )
by Grant Mckenzie Nov. 30, 2010

Nov. 30, 2010

Hi, I am using a Perspective Broker to service requests from a client on the same machine ( Windows XP ). This works fine most of the time however occasionally I see strange behaviour. The client uses connectTCP and provides a timeout of 5 seconds. Logging indicates that the client attempts to make a connection to the server, server logging in the remote methods indicates that the method is not called. Also my error callback on the client is not invoked after the timeout period. Unfotunately … [View More]

[Twisted-Python] twisted.web, url -> resource mapping and isLeaf questions
by David Nov. 30, 2010

Nov. 30, 2010

Hi, I am following "twisted in 60sec" series, but even the simple examples are a bit unclear to me, especially w.r.t. url mapping. For example: # assume the right imports... class MainPage(Resource): isLeaf = True def render_GET(self, request): return "somestring" resource = MainPage() factory = Site(resource) reactor.listenTCP(8880, factory) reactor.run() I was expecting that accessing any other 'path' besides the main url would cause 404, e.g. "http://localhost:8880/… [View More]

Twisted 10.2.0, the third Twisted release of 2010, has emerged from the mysterious depths of Twisted Matrix Labs, as so many releases before it. Survivors of the release process - what few there were of them - have been heard to claim that this version is "awesome", "even more robust", "fun-sized" and "oven fresh". Crossing several things that shouldn't ought to be, including the streams and the rubicon, I have assumed the triple responsibilities of feature author, project leader, *and* … [View More]

[Twisted-Python] ANNOUNCING Tahoe, the Least-Authority File System, v1.8.1
by Zooko O'Whielacronx Nov. 29, 2010

Nov. 29, 2010

Folks: Tahoe-LAFS uses Twisted extensively, and we try to contribute a few patches back to Twisted itself when we can. Regards, Zooko ANNOUNCING Tahoe, the Least-Authority File System, v1.8.1 The Tahoe-LAFS team is pleased to announce the immediate availability of version 1.8.1 of Tahoe-LAFS, an extremely reliable distributed storage system. Get it here: http://tahoe-lafs.org/source/tahoe/trunk/docs/quickstart.html Tahoe-LAFS is the first distributed storage system to offer "provider-… [View More]independent security" — meaning that not even the operators of your storage servers can read or alter your data without your consent. Here is the one-page explanation of its unique security and fault-tolerance properties: http://tahoe-lafs.org/source/tahoe/trunk/docs/about.html The previous stable release of Tahoe-LAFS was v1.8.0, which was released September 23, 2010 [1]. v1.8.1 is a stable bugfix release correcting a number of minor issues. It also includes a modest performance improvement in downloading, and a fix for a security issue involving HTTP proxies. See the NEWS file [2] for details. WHAT IS IT GOOD FOR? With Tahoe-LAFS, you distribute your filesystem across multiple servers, and even if some of the servers fail or are taken over by an attacker, the entire filesystem continues to work correctly, and continues to preserve your privacy and security. You can easily share specific files and directories with other people. In addition to the core storage system itself, volunteers have built other projects on top of Tahoe-LAFS and have integrated Tahoe-LAFS with existing systems, including Windows, JavaScript, iPhone, Android, Hadoop, Flume, Django, Puppet, bzr, mercurial, perforce, duplicity, TiddlyWiki, and more. See the Related Projects page on the wiki [3]. We believe that strong cryptography, Free and Open Source Software, erasure coding, and principled engineering practices make Tahoe-LAFS safer than RAID, removable drive, tape, on-line backup or cloud storage. This software is developed under test-driven development, and there are no known bugs or security flaws which would compromise confidentiality or data integrity under recommended use. (For all important issues that we are currently aware of please see the known_issues.rst file [4].) COMPATIBILITY This release is compatible with the version 1 series of Tahoe-LAFS. Clients from this release can write files and directories in the format used by clients of all versions back to v1.0 (which was released March 25, 2008). Clients from this release can read files and directories produced by clients of all versions since v1.0. Servers from this release can serve clients of all versions back to v1.0 and clients from this release can use servers of all versions back to v1.0. This is the twelfth release in the version 1 series. This series of Tahoe-LAFS will be actively supported and maintained for the forseeable future, and future versions of Tahoe-LAFS will retain the ability to read and write files compatible with this series. LICENCE You may use this package under the GNU General Public License, version 2 or, at your option, any later version. See the file "COPYING.GPL" [5] for the terms of the GNU General Public License, version 2. You may use this package under the Transitive Grace Period Public Licence, version 1 or, at your option, any later version. (The Transitive Grace Period Public Licence has requirements similar to the GPL except that it allows you to delay for up to twelve months after you redistribute a derived work before releasing the source code of your derived work.) See the file "COPYING.TGPPL.html" [6] for the terms of the Transitive Grace Period Public Licence, version 1. (You may choose to use this package under the terms of either licence, at your option.) INSTALLATION Tahoe-LAFS works on Linux, Mac OS X, Windows, Cygwin, Solaris, *BSD, and probably most other systems. Start with "docs/quickstart.html" [7]. HACKING AND COMMUNITY Please join us on the mailing list [8]. Patches are gratefully accepted -- the RoadMap page [9] shows the next improvements that we plan to make and CREDITS [10] lists the names of people who've contributed to the project. The Dev page [11] contains resources for hackers. SPONSORSHIP Tahoe-LAFS was originally developed by Allmydata, Inc., a provider of commercial backup services. After discontinuing funding of Tahoe-LAFS R&D in early 2009, they continued to provide servers, bandwidth, small personal gifts as tokens of appreciation, and bug reports. Google, Inc. sponsored Tahoe-LAFS development as part of the Google Summer of Code 2010. They awarded four sponsorships to students from around the world to hack on Tahoe-LAFS that summer. Thank you to Allmydata and Google for their generous and public-spirited support. HACK TAHOE-LAFS! If you can find a security flaw in Tahoe-LAFS which is serious enough that we feel compelled to warn our users and issue a fix, then we will award you with a customized t-shirts with your exploit printed on it and add you to the "Hack Tahoe-LAFS Hall Of Fame" [12]. ACKNOWLEDGEMENTS This is the sixth release of Tahoe-LAFS to be created solely as a labor of love by volunteers. Thank you very much to the team of "hackers in the public interest" who make Tahoe-LAFS possible.

So in my opinion, the function should really return the list of actually opened files in all cases, and not fallback to a list of possible list, otherwise the test case makes no sense. Of course this means trying all fds as last resort on platforms that don't provide a simpler way to do it. Doing it there or doing it by ignoring EBADF on close() later would be the same, as far as "suboptimization" is concerned. Another (nicer?) possibility to achieve the "close non standard fds" would be to use closefrom(). > I don't think the patch is quite correct, since ''at most'' the one extra > `os.listdir` file descriptor should be in the result set. Anything more > than that indicates the desired functionality isn't being provided. The > more correct test assertion would be that the output is ''either'' > range(3) or range(4). However, I'm not sure what you mean by the "uses a > pair of interconnected pipes" comment. Uses it for what? To implement > `os.listdir`? No, it's much worse :) While trying to fix the issue, I was surpised to notice that python had 5 opened fds by default here... After digging a bit further, I found out it is actually due to python being linked with libpthread, which installs a pair of pipe at init... > It would be nice if we didn't have to scan and close all of > range(RLIMIT_NFILES) on OpenBSD though.

[Twisted-Python] wxReactor Issues

Hello, My Twisted Python application with wxReactor crashes every time the user exits the application. The OnClose event calls a method that does reactor.stop(). I've ran this through gdb, and have noticed that this is because 2 threads aren't getting closed. What I find strange though, that is if the server closes the connection to the user, the 2 threads exit, and you are able to close the application our properly. I have tried running reactor.disconnectAll() before the reactor.stop() in my … [View More]

My simple batch processing system is moved here: http://code.google.com/p/batch-queue/ Seems to be reasonably functional. Any suggestions/contributions appreciated. One thing todo is to add some authentication. For now the server listens for xmlrpc requests and will run any command without authentication. In my current environment (single user system, firewalled), that's not a fatal flaw.
