Flightdeck-UI MVM and Library 0.2.0 (Stable) Released
by fdui＠openlight.com 27 May '03

27 May '03

This is a stable (production) release of the Flightdeck-UI library and Multi-Variable Monitor (MVM). Downloads are available from the project homepage ("http://www.openlight.com/fdui/"). The screenshots are here: "http://www.openlight.com/fdui/screens.html". The goal of the Flightdeck-UI project is to apply ideas from aircraft instrumentation design to general purpose user interfaces. The project consists of a library (which provides widgets based on the basic instruments of flight) and the Multi-Level Monitor (MVM) monitoring application. MVM can be quickly configured to track data from several sources (for example free disk space on your machine, the local weather, the number of visits to your website, etc.). It will then sit in some corner of your desktop, allowing you to read this information with an occasional glance. MVM includes a graphical editor and theme support. Support for multiple concurrency models in MVM plug-ins has been added in this release (asynchronous I/O and thread pool examples are included in the distribution). In addition, it is now easier to write simple plug-in modules, with functions that return integer or floating point numbers. For more information, see the README-MVM.TXT file ("http://www.openlight.com/fdui/README-MVM.TXT"). A number of bugfixes (particularly in the graphical editor) as well as enhanced error notification have also been added. Some of the new plug-ins (most notably the ones using thread pools) perform a clean shutdown when you exit MVM. If your Internet connection is hung up, you might have to wait a little for the I/O to time out so that the threads can stop (it is not possible to interrupt a Python thread). MVM and the Flightdeck-UI library are both open source/free software. They have been tested under Linux (RedHat 7.2) and under Windows 95. Questions can be emailed to originator of this message. Your ideas and participation will be appreciated!

Next meeting: Tuesday night
by Peter Hansen 26 May '03

26 May '03

The Python user's group for the Greater Toronto Area will meet at the usual location (519 Church St.) on Tuesday, May 27, from 8 to 10 pm. Details are here: http://web.engcorp.com/pygta/wiki/NextMeeting I'm planning an informal presentation about a new tool we've developed at Kaval, which is a Python-based testing framework for Javascript in Internet Explorer on Windows. The combination of Python tools involved includes: - PyUnit (aka standard module unittest, for the tests) - win32com (Mark Hammond's amazing library, for ActiveX control of IE) - Twisted (for serving test pages locally) In a nutshell, tests are written in Python in the usual manner, but the code under test executes within IE, served up from localhost, under ActiveX control. -Peter

ANN: managesieve 0.2
by Hartmut Goebel 26 May '03

26 May '03

Announcing: managesieve ============= Version 0.2 A MANGAGESIEVE client library for remotely managing Sieve scripts, including an interactive 'sieveshell'. This module allows accessing a Sieve-Server for managing Sieve scripts there. For more information about the MANAGESIEVE protocol see draft http://www.ietf.org/internet-drafts/draft-martin-managesieve-04.txt . What is MANAGESIEVE? -------------------- Sieve scripts allow users to filter incoming email. Message stores are commonly sealed servers so users cannot log into them, yet users must be able to update their scripts on them. This module implements a protocol "managesieve" for securely managing Sieve scripts on a remote server. This protocol allows a user to have multiple scripts, and also alerts a user to syntactically flawed scripts. This an interim measure as it is hoped that eventually Sieve scripts will be stored on ACAP. Availablity ----------- 'managesieve' is available for download at http://www.crazy-compilers.com/py-lib/#managesieve Requirements ------------ Requires Python >= 2.0 Not yet implemented ------------------- - Only athentication method LOGIN is currently supported. - STARTTLS is not yet implemented. - sieve-names are only quoted dump (put into quotes, but no escapes yet).

python-dev Summary for 2003-05-01 through 2003-05-15
by drifty＠bigfoot.com 23 May '03

23 May '03

+++++++++++++++++++++++++++++++++++++++++++++++++++++ python-dev Summary for 2003-05-01 through 2003-05-15 +++++++++++++++++++++++++++++++++++++++++++++++++++++ This is a summary of traffic on the `python-dev mailing list`_ from May 1, 2003 through May 15, 2003. It is intended to inform the wider Python community of on-going developments on the list and to have an archived summary of each thread started on the list. To comment on anything mentioned here, just post to python-list(a)python.org or `comp.lang.python`_ with a subject line mentioning what you are discussing. All python-dev members are interested in seeing ideas discussed by the community, so don't hesitate to take a stance on something. And if all of this really interests you then get involved and join `python-dev`_! This is the seventeenth summary written by Brett Cannon (going to grad school, baby!). All summaries are archived at http://www.python.org/dev/summary/ . Please note that this summary is written using reStructuredText_ which can be found at http://docutils.sf.net/rst.html . Any unfamiliar punctuation is probably markup for reST_ (otherwise it is probably regular expression syntax or a typo =); you can safely ignore it, although I suggest learning reST; its simple and is accepted for `PEP markup`__. Also, because of the wonders of programs that like to reformat text, I cannot guarantee you will be able to run the text version of this summary through Docutils_ as-is unless it is from the original text file. __ http://www.python.org/peps/pep-0012.html The in-development version of the documentation for Python can be found at http://www.python.org/dev/doc/devel/ . To view files in the Python CVS online, go to http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/python/ . .. _python-dev: http://www.python.org/dev/ .. _python-dev mailing list: http://mail.python.org/mailman/listinfo/python-dev .. _comp.lang.python: http://groups.google.com/groups?q=comp.lang.python .. _Docutils: http://docutils.sf.net/ .. _reST: .. _reStructuredText: http://docutils.sf.net/rst.html .. contents:: .. _last summary: http://www.python.org/dev/summary/2003-04-16_2003-04-30.html ====================== Summary Announcements ====================== So, to help keep my sanity longer than my predecessors I am no longer going to link to individual modules in the stdlib nor to files in CVS. It sucks down a ton of time and at least Raymond Hettinger thinks it clutters the summaries. Along the lines of the look of the summaries, I am trying out a new layout for listing splinter threads. If you have a preference in comparison to the old style or new style speak up and let me know. ========================== `Dictionary sparseness`__ ========================== __ http://mail.python.org/pipermail/python-dev/2003-May/035295.html Splinter threads: `Where'd my memory go?`__ __ http://mail.python.org/pipermail/python-dev/2003-May/035340.html After all the work Raymond Hettinger did on dictionaries he suggested two possible methods on dictionaries that would allow the programmer to control how sparse (at what point a dictionary doubles its size in order to lower collisions) a dictionary should be. Both got shot down on the grounds that most people would not know how to properly use the methods and are more likely to shoot themselves in the foot than get any gain out of them. There was also a bunch of talk about the "old days" when computers were small and didn't measure the amount of RAM they had in megabytes unless they were supercomputers. But then the discussion changed to memory footprints. There was some mention of the extra output one can get from a special build (all listed in Misc/SpecialBuilds.txt) such as Py_DEBUG. But the issue at hand is that there int, float, and frameobject free lists which keep alive any and all created constant values (although the frameobject is bounded in size). This is why if you do ``range(2000000)`` you won't get the memory allocated for all of those integers back until you shut down the interpreter. This led to the suggestion of just doing away with the free lists. There would be a performance hit since numerical constants would have to be reallocated if they are constantly created deleted, and then created again. It was also suggested to limit the size of the free lists and basically chop off the tail if they grew too large. But it turns out that the memory is allocated in large blocks that are chopped up by intobject.c. Thus there is no way to just get rid of a few entries without taking out a whole block of objects. ================================= `__slots__ and default values`__ ================================= __ http://mail.python.org/pipermail/python-dev/2003-May/035575.html Ever initialized a variable in a class that uses __slots__? If you have you may have discovered that the variable becomes read-only:: class Parrot(object): __ slots__ = ["dead"] dead = True bought_bird = Parrot() bought_bird.dead = False That raises an AttributeError saying that 'dead' is read-only. This occurs because the class attribute "overrides the descriptor created by __slots__" and "now appears read-only because there is no instance dict" thanks to __slots__ suppressing the creation of one. But don't go using this trick! If you want read-only attributes use a property with its set function set to raise an exception. If you want to avoid this problem just do your initialization of attributes in the __init__ call. You can also include __dict__ in __slots__ and then your instances will have a fully functioning instance __dict__ (new in 2.3). The key thing to come away with this twofold. One is the resolution order of attribute lookup when __slots__ is used which class/type and then the instances __slots__ attributes only if the class/type hierarchy did not turn up a data descriptor. The other is that __slots__ is meant purely to cut down on memory usage, nothing more. Do not start abusing it with little tricks like the one mentioned above or Guido will pull it from the language. ========= Quickies ========= `Draft of dictnotes.txt`__ After all the work Raymond Hettinger did to try to speed up dictionaries, he wrote a text file documenting everything he tried and learned. .. __: http://mail.python.org/pipermail/python-dev/2003-May/035246.html `_socket efficiencies ideas`__ This thread was first covered in the `last summary`_. Guido discovered that the socket module used to special-case receiving a numeric address in order to skip any overhead in bother to resolve the IP address. It has been put back into the code. .. __: http://mail.python.org/pipermail/python-dev/2003-May/035248.html `Demos and Tools in binary distributions`__ Jack Jansen asked where other platform-specific binary distributions of Python put the Demo and Tools directories. The thread ended with the winning solution be putting them in /Applications/Python2.3/Extras/ so they are a level below the root directory to prevent newbies from getting overwhelmed by the code there since it is not all simple. .. __: http://mail.python.org/pipermail/python-dev/2003-May/035252.html `updated notes about building bsddb185 module`__ Splinter threads: - `bsddb185 module changes checked in`__ Someone wanted the bsddb185 module back. Initially it was suggested to build that module as bsddb if the new bsddb3 module could not be built (since that module currently gets named bsddb). The final outcome was that bsddb185 will get built under certain conditions and be named bsddb185. .. __: http://mail.python.org/pipermail/python-dev/2003-May/035257.html __ http://mail.python.org/pipermail/python-dev/2003-May/035409.html `broke email date parsing`__ ... but it got fixed. .. __: http://mail.python.org/pipermail/python-dev/2003-May/035259.html `New thread death in test_bsddb3`__ This is a continuation from the `last summary`_.

You can never removed a directory unless you have direct access the the physical directory on the CVS root server. The best you can do is to empty the directory (make sure to get files named ".*") and assume people will do an ``cvs update -dP``. You can also remove the empty directories locally by hand if you like. .. __: http://mail.python.org/pipermail/python-dev/2003-May/035270.html `posixmodule.c patch to support forkpty`__ A patch was sent to python-dev incorrectly that tries to get os.forkpty to work on more platforms.

Lots of talk about heaps, priority queues, and other theoretical algorithm talk. It was felt that a more thorough API to allow for more fancy heap implementations would be helpful than what heapq provides. .. __: http://mail.python.org/pipermail/python-dev/2003-May/035343.html Weekly Python Bug/Patch Summary First one ended on `2003-05-04 <http://mail.python.org/pipermail/python-dev/2003-May/035292.html>`__.

This instantly led to the discussion of whether Python's binary distribution for Windows should be moved off of VC 6 to 7. The biggest issue is that apparently passing FILE * values across library boundaries breaks code. The final decision seemed to be that Tim, Guido, and developers of major extensions should get free copies. Then an end date of when Python will be moved off of VC 6 and over to 7 will be decided. None of this will affect Python 2.3 . This thread was 102 emails long. I don't use Windows. This was painful. .. __: http://mail.python.org/pipermail/python-dev/2003-May/035375.html .. _Python UK: http://www.python-uk.org/ .. _Visual C++ 2003: http://msdn.microsoft.com/visualc/

RELEASED Python 2.2.3c1
by Barry Warsaw 23 May '03

23 May '03

I'm happy to announce the release of Python 2.2.3c1 (release candidate 1). This is a bug fix release for the stable Python 2.2 code line. Barring any critical issues, we expect to release Python 2.2.3 final by this time next week. We encourage those with an interest in a solid 2.2.3 release to download this candidate and test it on their code. The new release is available here: http://www.python.org/2.2.3/ Python 2.2.3 has a large number of bug fixes and memory leak patches. For full details, see the release notes at http://www.python.org/2.2.3/NEWS.txt There are a small number of minor incompatibilities with Python 2.2.2; for details see: http://www.python.org/2.2.3/bugs.html Perhaps the most important is that the Bastion.py and rexec.py modules have been disabled, since we do not deem them to be safe. As usual, a Windows installer and a Unix/Linux source tarball are made available, as well as tarballs of the documentation in various forms. At the moment, no Mac version or Linux RPMs are available, although I expect them to appear soon after 2.2.3 final is released. On behalf of Guido, I'd like to thank everyone who contributed to this release, and who continue to ensure Python's success. Enjoy, -Barry

Kodos 1.5 - Python regular expression debugger
by stuff＠nonpoint.mailzilla.net 22 May '03

22 May '03

Kodos 1.5 has been released and is available at: http://kodos.sourceforge.net Changes since 1.3: - New feature: examine regex has been added. The examine feature is useful in the event when a regex that you have been editing no longer matches the text string. In some instances you may have inadvertantly added a character. Normally, the only indication that you have that the regex doesn't match is the status bar indicator. Although this alone may be useful, Kodos provides the examine feature to help pinpoint errors. By examining the regex, Kodos will locate the longest possible match by scanning the current regex. - Bug fixes: the clear all option behaves better - Help: the help section has been redone. About Kodos: Kodos is a regular expression designer, tester, debugger and validator that allows a developer to create and modify regular expressions against a test string. The intuitive grahpical interface allows the developer the ability to modify the regular expression (regex) and to see the effects against their test string in real-time. Key Features: - Matches can be easily viewed and each match can be seen distinctly - Regex groups and named groups are clearly displayed - Sample source code is shown so even python developers new to regular expressions can quickly add the produced regular expressions to their own projects. - Ability to load and save your test cases - Kodos relies on PyQt for the GUI elements. http://kodos.sourceforge.net
