[Twisted-Python] We have Apple's ear (cont'd)
by Cory Dodt Jan. 29, 2003

Jan. 29, 2003

Just a list of things I plan to ask for anyway (in no particular order): * hardware * money * engineers to fix Mac-related bugs in Twisted (or other dependencies) directly ... the list could provide me with a log of a run of trial to help here * a list of the problems python users are most likely to mention to Apple sales engineers, and solutions for same __________________________________________________ Do you Yahoo!?

[Twisted-Python] ANN: Twisted 1.0.2 [short version]
by Itamar Shtull-Trauring Jan. 29, 2003

Jan. 29, 2003

What's New in 1.0.2 =================== - Serial port support. - GPS (global positioning system), supporting NMEA 0183 and Rockwell Zodiac devices. - GTK2 event loop. - Improved event scheduling support. - Many new examples, including an example of Cocoa (Mac OS X) integration. - Fancy Win32 installer, with Start menu integration. - Large number of improvements to the SSH server. In addition, Twisted now ships with a command-line ssh client (conch), with same options as openssh client. Also included is a Tk GUI ssh client, that does not require a terminal emulator, and a program for generating ssh keys. - Simplified HTTP client API, for fetching URLs. - Dict protocol implementation (RFC 2229). - Improvements to cReactor, a networking event loop implemented in C. - Lenient mode for microdom, which allows parsing very non-standard HTML, and many improvements to the DOM support. - Trial, a unit testing framework, replaces use of Python's unittest.py. The API is almost identical to Python's. - Google querying support. - Shoutcast protocol support. - Client XML-RPC support. - Many improvements to Twisted's DNS support, both client and server. - Bug fixes, more tests and documentation.

[Twisted-Python] PLEASE: Add changelog entries when adding new features
by Itamar Shtull-Trauring Jan. 29, 2003

Jan. 29, 2003

Serial support, GPS support, GTK2 reactor, and no doubt other stuff were NOT mentioned as being added in the ChangeLog. This makes life harder for people writing release announcements, and for users who don't hear about all the nifty and cool new features you implemented. You do want people to use them, right? :) Oh, and is GTK2 listed in the "choosing a reactor" doc? -- Itamar Shtull-Trauring http://itamarst.org/ Available for Python, Twisted, Zope and Java consulting ***> http://VoteNoWar.org -- vote/donate/volunteer <***

[Twisted-Python] Ephemeral Adapters
by Kevin Turner Jan. 29, 2003

Jan. 29, 2003

Forever struggling with what is persistent and what is not, today I have an Adapter I think may be Ephemeral. (It's based on im.basechat.ChatUI, and its state is largely Protocol instances and things indexed by them.) What do I do about this? Should Componentized weed all Ephemerals from its _adapterCache in Componentized.__getstate__? It feels like too much mucking around with internals to do that in a subclass. -- The moon is waning crescent, 13.0% illuminated, 26.1 days old.

[Twisted-Python] Woven Refactor
by Donovan Preston Jan. 27, 2003

Jan. 27, 2003

Hello everyone in Twisted land, This is an experimental Woven View refactoring that I have been working on for the past two weekends. What does it do? * Uses a flat list of outstanding DOM nodes instead of recursion to keep track of where Woven is in the page rendering process * Removes View's dependency on DOMTemplate as a base class, in preparation for deprecation of DOMTemplate (all of the same semantics are now directly implemented in View). As a result, View has no base classes, making the inheritance chain cleaner. * Stores the namespace stacks (model, view, and controller name lookup chain) in the View directly, and each widget gets an immutable reference to it's position in the lookup chain when it is created, making re-rendering Widgets more reliable * Represents the namespace stacks as a cons-like tuple structure instead of mutable python lists, reducing confusion and list-copying; instead of copying the current stack lists each time a Widget is created, it just gets a reference to the current tuples for each of the stacks What does that mean? * The tracebacks are far shorter now, since we're no longer recursing deeply into the DOM tree * Namespace stack behavior is less buggy now; some of the outstanding mysterious bugs regarding rendering Widgets that have a Deferred model should hopefully go away * View has no base classes now, making the inheritance tree much shallower What do I need before I check it in? * Feedback! If you have a Woven application, please apply this patch and let me know if anything breaks. There are no API changes, and behavior should be the same (unless you were relying on the older, possibly buggy behavior; this shouldn't be the case) Assuming all goes well, I will check this in this weekend. Once I do, it paves the way for further cleanup of the Woven codebase. Onward and upward towards stable Woven! Donovan

Or is this too hard? -Andrew.

Jan. 26, 2003

This is from the python-au mailing list... I thought people might like to know that we've got yet another happy "customer" ;) The other thing I find amazing is the "about 5 minutes to understand" -- but then the docs are much better than when I first used Twisted :) -Andrew. ----- Forwarded message from Graeme Matthew <graeme_matthew(a)hotmail.com> ----- From: "Graeme Matthew" <graeme_matthew(a)hotmail.com> To: python-au(a)python.net Subject: [Python-au] Twisted Rocks !!!!! Date: Wed, 22 Jan 2003 15:46:03 +1100 Garth, mate this Twisted stuff rocks, I cannot believe a Win32 install is 700kb, took 1 minute to setup, and about 5 minutes to understand the basics in writing a client / server for data exchange, mate u have saved me heaps of stress, thanks again ! _________________________________________________________________ Add photos to your e-mail with MSN 8.

[Twisted-Python] FTPClient put
by Luciano Ramalho Jan. 26, 2003

Jan. 26, 2003

Can the FTPClient class be used to *send* files (STOR)? If yes, how? I've succesfully used the ftpclient.py example to retrieve a file listing from a server, but reading the API docs and the source of the ftp.py module has not given me a clue about how to *send* a file. Best regards, Luciano
