[Twisted-Python] subpackages not getting installed
by Andrea Arcangeli 26 Jan '05

26 Jan '05

Why? This below workaround make my software working again. I assume I must be missing something, otherwise I don't see the point of disabling packages without giving a command line switch to force a full install. (I did a quick search but I couldn't find a way to install without backing out the ignore switch) If this is just work-in-progress code feel free to ignore this email of course. Thanks.

[Twisted-Python] Twisted Wiki?
by Doug Ransom 26 Jan '05

26 Jan '05

Twisted is pretty hard to ramp up on. I wonder if twisted discussions and howtos were discussed in a wiki if twisted could become more documented and palatable to the masses? Doug Ransom

[Twisted-Python] live - debug?
by Luciano Andrade 25 Jan '05

25 Jan '05

Hello every one...I start using twisted matrix and develop an aplication (both server and client) realativly easy but it seems every once in a wille the server (some times the client too) hung showing traceback from an error, the problem is that the software works, but i like to put some debug(or a log system) to see if ther server crashed (sometimes acsidentally crash the reactor), can any one use something like that, also I like to use some sort of restart-on-halt system. Any ideas (except gramatical/ortographics corrections) are wellcome. PS: I really sorry if hurt to read my email. __________________________________________________ Correo Yahoo!

[Twisted-Python] Importing twisted.names.client blocks
by Ralf Schmitt 25 Jan '05

25 Jan '05

Hi, I started testing a program today which imported twisted.names.client. On every second run, the program didn't return from the import and hung for some time (until I pressed some key, strange...). Turns out, that I don't have Crypto installed and twisted.protocol.dns then tries to read 2 bytes from /dev/random, /dev/srandom, and /dev/urandom (in that order, until first success) in order to determine a random source. If it succeeds with one of those devices, it will also use that method later to read a random integer. The man page for urandom (on linux+fbsd) tells me that /dev/random is for 'uses that need very high quality randomness such as one-time pad or key generation' and that reads to /dev/random will block when the entropy pool is empty. In contrast /dev/urandom will not block, but it's output may be analyzed by an attacker ('Knowledge of how to do this is not available in the current non-classified literature'...but then that linux man page is very old...). I suggest that the usage of /dev/random should be stopped. If it doesn't bite you on import, it will do so later, when you're doing lots of dns request (a coworker of mine had written http crawler and told me, that it started getting slower after 3 hours or so, guess that was the time when /dev/random ran out of entropy). After all, when none of those devices is available, the code will also fallback to using random.randint. - Ralf

[Twisted-Python] Serving Compressed HTTP
by Doug Ransom 25 Jan '05

25 Jan '05

Any thoughts on serving compressed HTTP. I didn't see anything in twisted to do this out of the box. Do I need to create a new reactor? Here are some use cases: if a user-agent accepts compressed data - compress static content - compress static content, caching the result somewhere - return compressed "memory" data. - return compressed dynamic data - return compressed dynamic data only when certain mime types are supplied.

[Twisted-Python] VFS
by Tim Terlegård 25 Jan '05

25 Jan '05

I'm thinking about implementing an application that can browse filesystems (through ssh,ftp etc), databases, snmp mibs, zip/tar/gz files, a little toolbox where you can do all kinds of stuff with an mc like interface. Did anyone implement this already? I've checked the examples on the twistedmatrix site and all protocols like ssh, ftp, imap seem to have their own interface. IMHO, a common interface for browsing would be nice, something like VFS (e.g. Gnome VFS). With Gnome VFS you have the same interface for webdav, ftp, gzip, cdda and others. Also, IMHO, simpleftpclient.py and simplesshclient.py should differ only one or very few lines, the authentication part. Everything else should be the same. Am I making sense? What do you think about this? Tim

Hi Im new, This this is a good thing you guys are doing. The windows installs have all worked fine for me, however im having trouble with mandrake linux. My problem: I trying to instal on Mandrake linux 10 (run all patches) and for some reason my Python 2.3 directory does not have the config/makefile in it, could I just copy this from somewhere?

[Twisted-Python] [noob][Q] Is Twisted the right tool for my job?
by Tentochi 22 Jan '05

22 Jan '05

I am fairly experienced with Python (I also use wxPython a lot), and I have a fair amount of experience with TCP/IP in terms of mechanics and troubleshooting. I have almost no experience in network programming. I am working on a computer graphics application (Python/C++ hybrid) which demands a lot of CPU time. I am in the planning stages of converting it to distribute the work over many computers on the same local network (although I would eventually like to expand that as well). There will be a main computer which checks to see who is available to participate. That main computer will also be helping with the processing load. After that, it is basically all computers sending out either requests for information or sending data in response to a request (data can also be sent unsolicited). So I guess my question is--is Twisted more than what I need? I am sure it will do the job. I have read quite a bit of material on the web site already. But would it be faster and easier to just code this by hand or to use some other network programming framework/development tool? Thanks!!! Todd __________________________________ Do you Yahoo!?
