[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] What does the LGPL mean in terms of python?
by Chris Green 03 Jun '04

03 Jun '04

Hey folks, I've checked out the archives but almost everything I've read just amounted to "it's under the LGPL, read that". I understand the LGPL with regards to the classic case of C libraries. You can call the public functions, even add your own new public functions but the code that is in the library itself has to be released under the terms of the LGPL. The examples in the LGPL of using just the header file doesn't really map into python. For example, is a subclass a derivative work? By the LGPL, it seems to be since it's combined completely with the code that is under the LGPL. Let's say I had ChatServer derived from TCPServer, is it the intent of the licensing that my code must be placed under the LGPL? If subclassing is allowed to occur and those new classes can be placed under any license the user desires, it seems that any licensing inconvenience that doesn't involve cutting and pasting code can be worked around by merely extending the existing classes. If it's not allowed, I'm still not sure what the boundary lines are. This would be great information to add to the FAQ and include with the distribution as licensing clarifications and what the intent of the licensing scheme is. Thanks, Chris -- Chris Green <cmg(a)dok.org> Warning: time of day goes back, taking countermeasures.

[Twisted-Python] can you use log on a service thread
by Bill la Forge 30 May '04

30 May '04

Can you log from a service thread? I looked at log and didn't see any thread locking or anything, except for the following: threadable.synchronize(LogPublisher) threadable.whenThreaded(initThreads) Is logging thread safe? There seems to be a lot of magic here. ===== Bill la Forge http://www.geocities.com/laforge49/ ________________________________________________________________________ Yahoo!

Cool - definitely will. The whole conch area seems to be rather interesting - digging for more documentation on insults as well as I'm not quite the "read the API and code" learner yet. Now if someone could just show me the trick to learning this all faster, I'd be set;-) scp python.twisted.* me@brian.self://long/term/memory/ !!! Jamie

[Twisted-Python] Enterprise Rowobject and generating primary keys
by Guenther Starnberger 28 May '04

28 May '04

Hi all, I have a problem creating primary key values for enterprise rowobjects. The KeyFactory class says "This is deprecated. Use the underlying database to generate keys, or just roll your own.". As I am using Postgresql the ideal solution would be to just use the 'nextval' function (which is used as default value for the primary key in my schema, therefore I could skip this column in my insert statement). The problem now is, that I need to assign a value to the rowobject primary key column, otherwise i get an exception from twisted ('instance has no attribute...'). Just excluding the primary key column from my rowColumns attribute doesn't work either as this results in twisted to hang. Manually selecting the nextval function with the adbapi and using the result as primary key works, but this solution isn't really nice. Any other proposals for an elegant solution to create primary keys when inserting new rowobjects? cu /gst

[Twisted-Python] Twisted sshd examples?
by James R. Saker Jr. 28 May '04

28 May '04

Anyone familiar with a good implementation of twisted's ssh server? I'm looking to interface a menu application with SSH and instead of setting the python app as the UNIX shell, I'd like twisted to handle sshd so my application can permit different user logins (vs. being bound to a particular user's shell via that approach). The Twisted example provided (http://www.twistedmatrix.com/documents/current/examples/sshsimpleserver.py) appears to fail and I wonder if its outdated as the current API doesn't reference realm under conch: from twisted.conch import error, realm ... Traceback (most recent call last): File "sshd.py", line 3, in ? from twisted.conch import error, realm ImportError: cannot import name realm Thanks... Jamie

[Twisted-Python] TieredServices
by Bill la Forge 27 May '04

27 May '04

I've cleaned up the TieredServices code for handling partial failure during initialization of related services. Its posted to my web site, together with test code, at http://compstrm.sourceforge.net/twcs/tieredservices.html This code DOES NOT use anything from CompStrm. Please consider this a contribution to Twisted, as I'm consigning the copyright to Glyph so that it can be included. (Consignment contingent on inclusion, of course.) ===== Bill la Forge http://www.geocities.com/laforge49/ ________________________________________________________________________ Yahoo!
