python-dev Summary for 2004-06-01 through 2004-06-15
by Brett Cannon 21 Jun '04

21 Jun '04

python-dev Summary for 2004-06-01 through 2004-06-15 ++++++++++++++++++++++++++++++++++++++++++++++++++++ This is a summary of traffic on the `python-dev mailing list`_ from June 01, 2004 through June 15, 2004. It is intended to inform the wider Python community of on-going developments on the list. To comment on anything mentioned here, just post to `comp.lang.python`_ (or email python-list(a)python.org which is a gateway to the newsgroup) 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 forty-third summary written by Brett Cannon (wonder if that summary count is correct?). To contact me, please send email to brett at python.org ; I do not have the time to keep up on comp.lang.python and thus do not always catch follow-ups posted there. 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; it's simple and is accepted for `PEP markup`_ and gives some perks for the HTML output. 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`_. .. _PEP Markup: 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/ and should be used when looking up any documentation on new code; otherwise use the current documentation as found at http://docs.python.org/ . PEPs (Python Enhancement Proposals) are located at http://www.python.org/peps/ . To view files in the Python CVS online, go to http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/python/ . Reported bugs and suggested patches can be found at the SourceForge_ project page. The `Python Software Foundation`_ is the non-profit organization that holds the intellectual property for Python. It also tries to forward the development and use of Python. But the PSF_ cannot do this without donations. You can make a donation at http://python.org/psf/donations.html . Every penny helps so even a small donation (you can donate through PayPal or by check) helps. .. _python-dev: http://www.python.org/dev/ .. _SourceForge: http://sourceforge.net/tracker/?group_id=5470 .. _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 .. _PSF: .. _Python Software Foundation: http://python.org/psf/ .. contents:: .. _last summary: http://www.python.org/dev/summary/2004-06-01_2004-06-15.html .. _original text file: http://www.python.org/dev/summary/2004-06-01_2004-06-15.ht Summary Announcements ===================== Wow, two summaries written in a single week. Hell has not frozen over, don't worry; work has just not started yet. =) Summaries ========= -------------------------------- New PEP on bytecode verification -------------------------------- As it stands now, unless you are running a debug build of Python, there are no checks that the bytecode being executed by the interpreter is valid. It is not terribly difficult to crash the interpreter with blatently invalid bytecode. In an attempt to resolve this, `PEP 330`_ has been written in hopes of coming up with a Python module in the stdlib that can have bytecode passed to it and attempt to perform some basic verification on it. .. _PEP 330: http://python.org/peps/pep-0330.html Contributing threads: - `PEP 330 Python bytecode verification <http://mail.python.org/pipermail/python-dev/2004-June/045082.html>`__ -------------------- 2.4a1 coming up soon -------------------- Python 2.4a1 should be coming out early July. If you have some bugs or patches you want to see in 2.4 then read Anthony's announcement for general guidelines on how to go about this. Jeremy Hylton pointed out that since the AST branch did not make it in before this announcement it would not be included in 2.4 (thus guaranteeing a sprint topic for PyCON 2005). Generator expressions *are* in this alpha with late bindings. If late bindings work out for you, or if you have an explicit use case in working code for early bindings, please speak up. Contributing threads: - `pre-announce: Python 2.4a1 is about a month away <http://mail.python.org/pipermail/python-dev/2004-May/045028.html>`__ -------------------------------------------------- The shaky courtship of 2.4 and function decorators -------------------------------------------------- With 2.4a1 ominously approaching on the horizon, Guido asked what people thought of holding off on including function decorators for 2.5. Some people said to put it in and if that meant using Guido's then so be it. Others said to wait and let Guido have more time since he wanted to consider Java 1.5's syntax. Guido said he would ask at EuroPython_ for more opinions. .. _EuroPython: http://www.europython.org/ Contributing threads: - `functions decorators in 2.4? <http://mail.python.org/pipermail/python-dev/2004-June/045124.html>`__ - `Dropping decorator syntax for 2.4? <http://mail.python.org/pipermail/python-dev/2004-June/045125.html>`__ ----------------------------------------------------------- Why Stackless is not about to be incorporated into the core ----------------------------------------------------------- Someone asked why Stackless_ is still not part of the Python core. After a bunch of talking, Guido spelled out a couple of reasons. One was a lack of a clear spec; if it is not obvious how it will behave it can't go in. Another was whether it could reasonably work on Jython; Python the language needs to be portable enough to be coded in C or Java. A third point was not wanting to rely on platform hacks in order for something to work; Stackless doesn't use the C stack and that can complicate things (and Guido put longjmp() from ISO C in this category so don't ever think of using it in a patch). In other words Stackless is not going to be integrated into the core at this time. .. _Stackless: http://www.stackless.com/ Contributing threads: - `Stackless Python <http://mail.python.org/pipermail/python-dev/2004-June/045074.html>`__ - `Re: Stackless Python <http://mail.python.org/pipermail/python-dev/2004-June/045098.html>`__ ------------------------------------------------------ Remember, some stdlib modules are maintained elsewhere ------------------------------------------------------ Greg Ward reminded python-dev that optparse is maintained as Optik_ and as a separate project. Some other modules are also maintained like this, so it is something to keep an eye out for if you are writing patches or reporting a bug. .. _Optik: http://optik.sf.net/ Contributing threads: - `Reminder: optparse.py is auto-generated <http://mail.python.org/pipermail/python-dev/2004-June/045176.html>`__ -------------- Python Bug Day -------------- The First Python Bug Day took place on June 5th, led by AM Kuchling. The end results are listed at http://www.python.org/moin/PythonBugDayStatus and look very good. Since SF troubles cropped up during the day (both frustration with people not being able to add files to bugs and patches created by other people and SF CVS going down), discussion of getting off of SF came up (this was also mentioned in several other minor threads). The desire to host off-site were brought up, but the issue of having enough volunteers to handle the load of managing a CVS or Subbversion repository was brought up. Also moving over to Roundup or GForge on a server under our control was also brought up. Nothing looks like it is going to happen any time soon, though (at least not until 2.4 is out the door). The next Bug Day has been tentatively scheduled for July 10. Contributing threads: - `Python bug day? <http://mail.python.org/pipermail/python-dev/2004-June/045090.html>`__ - `Bug day outcome <http://mail.python.org/pipermail/python-dev/2004-June/045235.html>`__ ---------------------------------------------------------- What it takes to have something to support weak references ---------------------------------------------------------- (should have been in last summary) Why don't strings and such support weak references? Turns out that variable-sized objects (i.e., tp_itemsize specified) cannot support them without direct support hard-coded in the struct. Since it would require more space and extra code for deallocation (and thus incur a performance penalty) for such common types as strings and tuples, it was decided that for such an infrequently used ability (at least in this case) it would not be worth the cost of adding support. Contributing threads: - `Why aren't more things weak referencable <http://mail.python.org/pipermail/python-dev/2004-May/045006.html>`__ ------------------------- Heterogeneous comparisons ------------------------- The list was reminded that in the future at some point, comparisons between heterogeneous types will raise TypeError except for '==' and '!='. This brought up the discussion of comparing floats to longs. Guido said he is going to make sure that they can still be compared without issue (part of the reason true division was introduced). People talked about the best way to go about it, but it was mostly just talk since this is not about to go into the core. Contributing threads: - `Comparing heterogeneous types <http://mail.python.org/pipermail/python-dev/2004-June/045111.html>`__ ----------------------- Finalizing Decimal type ----------------------- Facundo Batista posted an email summing up the last nagging features for the Decimal type and `PEP 327`_. He said he would post an updated PEP (which he has done) and get input from Tim Peters. Looks like this is almost in! .. _PEP 327: http://python.org/peps/pep-0327.html Contributing threads: - `Decimal issues - Conclusion <http://mail.python.org/pipermail/python-dev/2004-June/045209.html>`__ --------------- Free Icon books --------------- Tim Peters posted links to links to PDFs of three significant books on Icon_ (see the email for the links). Why would Python programmers care about the Icon programming language? Well, Python got the idea of generators from Icon. Plus it never hurts to know more languages, if anything just for new ideas for Python or to be able to emphatically state Python is better. =) Also, the book, 'The Icon Programming Language', is essentially the *only* book describing how a scripting language that is non-trivial is implemented. .. _Icon: http://www.cs.arizona.edu/icon/ Contributing threads: - `Free Icon books <http://mail.python.org/pipermail/python-dev/2004-June/045231.html>`__ ---------------------------------------- Documenting undocumented C API functions ---------------------------------------- Thomas Heller updated Doc/tools/undoc_symbols.py (which finds out what C API code is undocumented) and ran it. The list of undocumented C code is listed at http://starship.python.net/crew/theller/moin.cgi/Documenting_25CorePythonAp… . If you would like to help with documenting, helping with documenting what is listed at the wiki would be great. Contributing threads: - `undocumented api functions <http://mail.python.org/pipermail/python-dev/2004-June/045308.html>`__ --------------------------------------------- Tool for side-by-side diffs outputted in HTML --------------------------------------------- http://www.python.org/sf/914575 has a patch that adds the necessary code and a tool script for side-by-side diffs using difflib that output in a nice HTML format. While the code has not been accepted yet, I personally know how useful this functionality can be so I thought I would just let people know about the code. And if you find this code helpful, then doing a code review and adding a comment on the patch would be helpful in getting the code accepted, especially after the author gets his next patch uploaded. Contributing threads: - `Side by Side Differencing Patch <http://mail.python.org/pipermail/python-dev/2004-June/045304.html>`__ - `HTML side by side diff patch 914575 <http://mail.python.org/pipermail/python-dev/2004-June/045361.html>`__ ----------------------------------- Removing CLRFs in PCbuild directory ----------------------------------- Martin v. Lowis fixed the vcproj files in the PCbuild directory to have the proper line endings. Problem is that you must run ``cvs update -A`` on your PCbuild directory to add the -kb tag on the files since it is a sticky tag. Contributing threads: - `Changing PCBuild/*.vcproj to text mode <http://mail.python.org/pipermail/python-dev/2004-June/045401.html>`__ -------------------------------------------------------- Bounding free list creation for ints and such ain't easy -------------------------------------------------------- Bounding the size of the memory used by ints and other built-ins that have a custom allocator was brought up. The suggestion of moving them to pymalloc was suggested, but it was pointed out it would make it slower and waste more space on some platforms. And the ideas on how to deal with this all seemed difficult. No code was committed in the end. Contributing threads: - `Object free lists <http://mail.python.org/pipermail/python-dev/2004-June/045403.html>`__ ------------------------------------- How to search the python-dev archives ------------------------------------- One idea is to use gmane.org to do your searches since they index the mailing list. The one that I (and apparently Tim Peters) use is to do a Google search with ``site:mail.python.org python-dev`` at the beginning. I actually search the python-dev archives using the same technique; ``site:www.python.org "python-dev Summary"``. Contributing threads: - `python-dev archive searching ? <http://mail.python.org/pipermail/python-dev/2004-June/045325.html>`__

ANN: ElementTree 1.2 final (june 18, 2004)
by Fredrik Lundh 19 Jun '04

19 Jun '04

The Element type is a simple but flexible container object, designed to store hierarchical data structures, such as simplified XML infosets, in memory. The ElementTree package provides a Python implementation of this type, plus code to serialize element trees to and from XML files. The 1.2 release adds limited support for XPath and XInclude, and also fixes a number of serialization bugs, mostly related to extensive use of namespaces and unicode in tags and attribute names. For a complete list of changes, see the CHANGES document in the source kit. You can get the ElementTree toolkit from: http://effbot.org/downloads Documentation, articles, and some code samples (including an XML-RPC unmarshaller in 16 lines) are available from: http://effbot.org/zone/element.htm enjoy /F

process.py: updated popen5 module
by Peter Åstrand 19 Jun '04

19 Jun '04

Seven months ago, I announced my popen5 module. Since then, I've made many changes: * The module has been renamed, and is now called 'process'. (As a separate project, this is bad name since there are already several other modules called 'process', but one explicit goal of this module is to have it included in the Python standard library. In this context, 'process' is the best suggestion so far.) * Support for Windows platforms has been added. Currently, the win32all extensions are required. (The idea is to remove this dependency by writing a small extension module, in the same way as _winreg works. Help is always appreciated...) * The run() function has been replaced with call() and callv(). See the documentation for details. * The attributes fromchild, tochild, and childerr has been renamed to stdout, stdin and stderr. * Many small improvements has been made, both in the module itself and the module tests. Note: The PEP is not yet updated to reflect these changes. The license is Python-style. The latest revision is 1.2, and is available from http://www.lysator.liu.se/~astrand/popen5/ . /Peter Astrand <astrand(a)lysator.liu.se> <P><A HREF="http://www.lysator.liu.se/~astrand/popen5/">process.py revision 1.2</A> - updated popen5 module (2004-06-04)

RELEASED: pynits 040617
by François Pinard 17 Jun '04

17 Jun '04

Hi, my Python and Vim friends. Here is the second release of `pynits'. The documentation has been revised. Messages have been internationalised, defaulting to English, with French as a localisation. Thanks to those who were courageous enough to look at the initial release! :-) ============================================================================== Pynits is a useful tool while editing Python source code from within Vim, for tidying up individual sources lines, and doing some auxiliary tasks. I find it particularly helpful when formatting lines containing long or complex expressions. This tool requires a Python-enabled Vim. The Pynits tool may be downloaded from: http://fp-etc.progiciels-bpi.ca/showfile.html?mode=archives while installation directions may be found at: http://fp-etc.progiciels-bpi.ca/showfile.html?name=pynits/README The documentation file is also available on the Web as: http://fp-etc.progiciels-bpi.ca/showfile.html?name=pynits/pynits.txt There are three sets of commands in this tool. A first set takes an entire line of Python source code (which may contain line continuations) and works hard at choosing a "best" surface representation, completely rebuilt from its syntax tree. A second set is meant to discover and report various formatting nits, and even to correct them when a correction recipe is known. A final set contains random commands, usually for a few simple reformatting tasks. -- François Pinard http://www.iro.umontreal.ca/~pinard

Everyone should upgrade if possible to this bugfix release. 2.4a should be ready by mid-July. The email server I use (not under my control) decided to change their IMAP server. Unfortunately it is not playing nicely with Thunderbird or the mbox format, so I am being forced to use Apple Mail in order to delete emails. Since I am not used to Mail's threading I may have missed some threads. If I did, sorry about that and they will be covered in the next summary. Summaries ========= ----------------------------- Generator expressions are in! ----------------------------- Generator expressions have been checked in. They are currently using late bindings (see the `last summary`_ for an explanation of what that means). If using late binding semantics doesn't work for you, do express your opinion since it can be changed before the beta is released. Contributing threads: - `PEP 289 - Generator Expressions <http://mail.python.org/pipermail/python-dev/2004-May/044684.html>`__ - `PEP 289 - Generator Expressions - Let's Move For ward <http://mail.python.org/pipermail/python-dev/2004-May/044643.html>`__ ------------------------------------------ Following the docs, not the implementation ------------------------------------------ What happens if you rely on an implementation when the documentation explicitly states the semantics in another way? Well, "you will pay for your sin in a special kind of hell set aside for people who take the implementation as the spec" according to Guido. Some things in CPython go against the spec for performance reasons, but there is nothing stopping from it being changed at another point to more closely follow the spec. Contributing threads: - `Passing compile(...,'exec') code to 'eval' <http://mail.python.org/pipermail/python-dev/2004-May/044683.html>`__ --------------------------------------------- What you need to get a module into the stdlib --------------------------------------------- In order to prevent the stdlib from getting bloated with unneeded modules, new ones need to have seen use "in the field", as Guido put it. Contributing threads: - `New Subscriber <http://mail.python.org/pipermail/python-dev/2004-May/044709.html>`__ --------------------- 2.3.4 is out the door --------------------- Python 2.3.4 has been released. Being a bugfix there are no new features. It is recommended that everyone upgrade to this version. Contributing threads: - `Python 2.3.4 schedule <http://mail.python.org/pipermail/python-dev/2004-May/044661.html>`__ - `release23-maint tree closed for 2.3.4rc1 <http://mail.python.org/pipermail/python-dev/2004-May/044771.html>`__ - `Python 2.3.4, release candidate 1 - BUG FIX <http://mail.python.org/pipermail/python-dev/2004-May/044854.html>`__ - `python 2.3.4 delayed for a week <http://mail.python.org/pipermail/python-dev/2004-May/044921.html>`__ - `2.3.4 release this thursday <http://mail.python.org/pipermail/python-dev/2004-May/044954.html>`__ - `ELEASED Python 2.3.4 (final) <http://mail.python.org/pipermail/python-dev/2004-May/044984.html>`__ ----------------------- IPv6 for Windows in 2.4 ----------------------- For those of you wanting IPv6 support on Windows in the binary build, you will get it in 2.4 . The reason it isn't in 2.3.x is that the branch is compiled with VC 6 which can only compile in IPv6 support with a separate SDK. VC 7, on the other hand, does not have this issue. Contributing threads: - `IPv6 support in Win binary again <http://mail.python.org/pipermail/python-dev/2004-May/044779.html>`__ ----------------------- cookielib in the stdlib ----------------------- A module named cookielib was added to the stdlib to allow transparent handling of cookies for modules such as urllib2. Contributing threads: - `cookielib module in 2.4? <http://mail.python.org/pipermail/python-dev/2004-May/044785.html>`__ - `cookielib <http://mail.python.org/pipermail/python-dev/2004-May/045015.html>`__ ------------------------ cmp doesn't call __cmp__ ------------------------ It was pointed out that calling ``cmp(x,x)``` does not call ``x.__cmp__(x)`` but instead uses PyObject_RichCompareBool(). The issue with this is that PyObject_RichCompareBool() has a short-circuit for when the object being compared is the same, thus skipping a possible call to x.__cmp__ and saving some time. This can be an issue, though, if you want something other than True or False to be returned. Basically what came out of this thread was that C functions can short-circuit comparisons so be careful if you want to make sure that __cmp__ is called; use '==' and the other comparison operators instead. Contributing threads: - `cmp(x,x) <http://mail.python.org/pipermail/python-dev/2004-May/044885.html>`__ ---------------------------------- Posssible improvements to import.c ---------------------------------- Tim Peters asked if anyone knew the working details of import.c; no one spoke up. The question was brought up because Tim would like to see failed imports not lead to mangled modules being in sys.modules and thus being considered properly imported. The suggestion of also handling circular imports came up as well. Contributing threads: - `import.c <http://mail.python.org/pipermail/python-dev/2004-May/044998.html>`__

ANN: ElementTree 1.2 release candidate 1
by Fredrik Lundh 16 Jun '04

16 Jun '04

The Element type is a simple but flexible container object, designed to store hierarchical data structures, such as simplified XML infosets, in memory. The ElementTree package provides a Python implementation of this type, plus code to serialize element trees to and from XML files. The 1.2 release adds limited support for XPath and XInclude, and also fixes a number of serialization bugs, mostly related to extensive use of namespaces and unicode in tags and attribute names. For a complete list of changes, see the CHANGES document in the source kit. You can get the ElementTree toolkit from: http://effbot.org/downloads Brief documentation and some code samples (including an XML-RPC unmarshaller in 16 lines) are available from: http://effbot.org/zone/element.htm enjoy /F

[ANNOUNCE] Sixteenth release of PythonCAD now available
by Art Haas 16 Jun '04

16 Jun '04

Hi. Due to packaging problems in the fifteenth release, and a code snafu the bit the Cocoa interface, I'm releasing the sixteenth version of PythonCAD. The missing Cocoa files have been added, and a patch addressing the Layer problems on Cocoa have been applied. Additionally a small patch for chamfers and fillets is in this release as well, but otherwise this release is identical to the fifteenth release. My thanks to David Haas for contributing the Cocoa interface code, and resolving the problems in the fifteenth release.

ANN: Spineless game engine 0.0.1
by Jussi Lepistö 16 Jun '04

16 Jun '04

Spineless is a generic 3D game engine implemented in Python with C++ optimizations. Focus is on clean design and ease of use, not pure speed. It is still very incomplete and not really useful yet for serious use, but I would appreciate feedback, comments and suggestions. Notable features: - Clean design - Both 2D and 3D graphics accelerated with OpenGL - Custom, completely resolution-independent GUI module - Resource management (fonts, textures, sound samples) - Scene graph with collision detection - Physical simulation with collision response and friction Note that the engine is still very unpolished and unoptimized and lacks proper documentation. However, you can mail me with questions and suggestions. You can find the Spineless web page here: http://spineless.sourceforge.net/ -Jussi

ANN: IbPy 0.4 - Interactive Brokers Python API
by Troy Melhase 16 Jun '04

16 Jun '04

IbPy - Interactive Brokers Python API ===================================== IbPy 0.4 Released 15 June 2004 What is IbPy? ------------------------------------------------------------------------------ IbPy is a third-party implementation of the API used for accessing the Interactive Brokers on-line trading system. IbPy implements functionality that the Python programmer can use to connect to IB, request stock ticker data, submit orders for stocks and futures, and more. What's new in this release? ------------------------------------------------------------------------------ The focus of this release is compatibility with recent versions of the TWS application. TWS Build 826.4 is the most current as of this writing, and IbPy functions as expected with it. The other notable features of this release are: * Execution filters * Orders with combo legs * Method 'request_auto_open_orders' * Method 'request_all_open_orders' * Method 'request_managed_accounts' Many thanks to Mike Lynch for his testing and feedback. Where can I get IbPy? ------------------------------------------------------------------------------ IbPy is available for download from SourceForge.net. http://sourceforge.net/project/showfiles.php?group_id=53862 Project page: http://ibpy.sourceforge.net/ How do I use IbPy? ------------------------------------------------------------------------------ In order to use IbPy, the TWS application provided by IB must be installed and running. See the note "What is TWS?" for more information. IbPy is used in the same manner as all socket clients supplied by Interactive Brokers. The typical sequence of operations is: * Start the browser-based or stand-alone TWS application * In TWS, enable socket clients via the Configure -> API menu * Connect to TWS from external application * In TWS, accept the incoming connection * External application requests ticker updates, sends orders, receives account data, portfolio data, etc. To connect to TWS and interact with the brokers trading system, the Python developer defines methods or functions to act as callbacks and associates these with an Ib.Socket.SocketConnection object. Refer to the Demo.py file in the distribution for a complete example. In lieu of IbPy documentation, developers are referred to the IbPy source code and the documentation supplied by Interactive Brokers. What are the requirements? ------------------------------------------------------------------------------ IbPy requires Python 2.3 or newer. Previous versions may or may not work. TWS requires a web browser capable of executing Sun(R) Java(tm) applets. TWS can also be started directly with Sun(R) Java(tm) and the stand-alone package supplied by Interactive Brokers. What is Interactive Brokers? ------------------------------------------------------------------------------ >From the "About The Interactive Brokers Group" page (http://interactivebrokers.com/html/companyInfo/about.html): The Interactive Brokers Group is a group of electronic brokerage and market making firms at the forefront of the electronic brokerage industry. We have revolutionized the securities and derivatives markets by providing investors with high-speed, direct access to stock, options and futures products worldwide. We specialize in providing investors with technology that offers efficient, fast access to the world's markets at the lowest possible cost. What is TWS? ------------------------------------------------------------------------------ >From the page "Trader Execution and Clearing System Features" (http://interactivebrokers.com/html/companyInfo/market_ib.html): * IB's Trader Workstation can be run directly from your browser, or you can install it on your PC and run it from your desktop. This Java based application allows traders to quickly enter orders and see results. * Direct Access: Unlike other "online" brokers that send your order through an e-mail type system, IB offers a direct-access order entry system that transmits your order to the proper market center, usually within one second of entry. * Real-Time Streaming Quotes: Display real-time, streaming quotes for markets of interest to the investor. Quotes are live and change continuously as the markets change, no periodic manual update or "refresh" is required. What Else? ------------------------------------------------------------------------------ IbPy is not a product of Interactive Brokers, nor am I affiliated with IB. I am a satisfied IB customer, of course. IbPy is installed with distutils. Refer to the Python distutils documentation for more information. The digest version is: # tar xzf IbPy-0.4.tar.gz # cd IbPy-0.4 # python setup.py install The TWS demo system is available here: http://interactivebrokers.com/cgi-pub/jtslink.pl?user_name=edemo The stand-alone TWS and other API software is available from IB: http://interactivebrokers.com/ IbPy is licensed under the BSD License. I'm very interested in your experience with IbPy. Please drop me an note with any feedback you have. Troy Melhase mailto:troy@gci.net

[ANNOUNCE] Fifteenth release of PythonCAD now available
by Art Haas 15 Jun '04

15 Jun '04

I'm pleased to announce the fifteenth development release of PythonCAD, a CAD package for open-source software users. As the name implies, PythonCAD is written entirely in Python. The goal of this project is to create a fully scriptable drafting program that will match and eventually exceed features found in commercial CAD software. PythonCAD is released under the GNU Public License (GPL). PythonCAD requires Python 2.2 or Python 2.3. The interface is GTK 2.0 based, and uses the PyGTK module for interfacing to GTK. The design of PythonCAD is built around the idea of separating the interface from the back end as much as possible. By doing this, it is hoped that both GNOME and KDE interfaces can be added to PythonCAD through usage of the appropriate Python module. Addition of other interfaces will depend on the availability of a Python module for that particular interface and developer interest and action. The fifteenth release of PythonCAD offers users on Mac OS X a native, Cocoa based interface utilizing the Python/Objective-C bridge. The Python/Objective-C code is available at http://pyobjc.sf.net/. A nice side benefit from the development of the Cocoa code was the exposure of various bugs and design issues in the interface neutral code. Bugs exposed by this work have been fixed, and several design improvements are now in the code thanks to this work. The Cocoa interface code is contributed by David Haas, and I thank him greatly for his work. This release includes several more undo/redo improvements. The addition and removal of points on a polyline can now be undone or redone, and assorted other editing operations have improved undo/redo handling as well. A variety of bug fixes have also been added in this release. Small bugs regarding entity searching, arc boundaries, layer addition and removal, and entity storage have been fixed. A few code improvements appear in this release also. The mailing list for the development and use of PythonCAD is available. Visit the following page for information about subscribing and viewing the mailing list archive: http://mail.python.org/mailman/listinfo/pythoncad Visit the PythonCAD web site for more information about what PythonCAD does and aims to be: http://www.pythoncad.org/ Come and join me in developing PythonCAD into a world class drafting program!

Alpha 2.3.3 port to Symbian OS UIQ (P800, P900) available
by Tim Ocock 15 Jun '04

15 Jun '04

At http://www.monkeyhouse.eclipse.co.uk/mobile/python.htm you can find my independent attempt to port Python to Symbian OS devices. It is a new port from the generic Python 2.3.3 sources. The Python interpreter works in console mode, and most of the standard library modules work as expected. I am launching the project publicly now as I have completed the first proof of concept and am now inviting ideas and contributions. There is still lots of work to do. The software runs inside the emulator, but is of no use on a real device as there is no way to enter text (except possibly with an IR keyboard, but I haven't tried that). I have not seen the Nokia Series 60 runtime, but am aware of it. I don't know what their intentions are regarding open source licensing, but if their work is available on appropriate terms, then I would rather use that for this project than reinvent the wheel. Currently, the Python interpreter runs and you can interactively enter Python programs or code fragments. Please get in touch if you are interested in contributing.

RELEASED: pynits 040615
by François Pinard 15 Jun '04

15 Jun '04

Hi, my Python and Vim friends. Here is the initial release of `pynits', and the beginning of its documentation file. I hope some courageous souls will help me at eradicating packaging and other blunt bugs! :-) *pynits.txt* Tidying up Python files TIDYING PYTHON CODE WITHIN VIM François Pinard pinard(a)iro.umontreal.ca Pynits is a tool which I find useful while editing Python source code with Vim, for tidying up individual sources lines, and some auxiliary tasks. It is particularly helpful when formatting lines holding long or complex expressions. This tool requires a Python-enabled Vim. 1. Introduction |pynits-introduction| 2. Finding nits |pynits-finding-nits| 3. Reformatting lines |pynits-reformatting| 4. Other commands |pynits-other-commands| The Pynits tool may be downloaded from: http://fp-etc.progiciels-bpi.ca/showfile.html?mode=archives while installation directives may be found at: http://fp-etc.progiciels-bpi.ca/showfile.html?name=pynits/README This file you are reading is also available on the Web as: http://fp-etc.progiciels-bpi.ca/showfile.html?name=pynits/pynits.txt WARNING: This tool is in alpha state, its specifications may change. Write to the author for corrections, suggestions or bug reports. ============================================================================== 1. Introduction *pynits-introduction* I once had to take over the maintenance of a set of big Python modules, written by someone without much concern about source line length limits, and also a bit lacking in the area of sound coding standards. The sources were hard to read on an usual terminal screen, hard to print without stunts on a printer, hard to edit: in a word, hard to maintain. When it comes to source coding standards, people develop religious feelings. My personal coding practices, which are somehow reflected in this tool, are surely debatable and questionable, yet I dare to think they are quite reasonable. I use an eclectic choice of good ideas from various sources: the Python mode as written for GNU Emacs, the standard Python plugin for Vim, Guido's own style as he documented it, some relevant parts of GNU and Gnits standards, good horse sense, but also, my own programming experience, accumulated for a good while by now. Source code lines are often carefully crafted by programmers, and a reformatting tool may defeat local art work. This is why I think reformatting is best done from with a scalpel, like Vim may be, than operated in bulk or in batch. The programmer may choose to accept or refuse, on a line basis, suggestions made by a tool like this one. There are three sets of commands in this tool. The first set is meant to discover and report various formatting nits. The programmer may then ask the tool for correcting them, when a correction recipe is known. The second set takes a whole Python source line, possibly continued, and fully rebuilds a surface representation from its syntax tree. The third set contains a few random commands for simple tasks.

ANN: PyGUI 1.3 released (Greg's Pythonic GUI Framework)
by greg 14 Jun '04

14 Jun '04

PyGUI (Greg's Pythonic GUI Framework) Version 1.3 ================================================= Some of you may remember the project I started a few years ago to define a pythonic GUI API for implementation on multiple platforms. I didn't make much progress on it for a while, but the project wasn't dead, just resting. Following a recent burst of activity, I am now pleased to announce the release of version 1.3. This release marks a milestone in the development of PyGUI, because, for the first time, implementations for two platforms are included: * MacOS X, via Carbon * Linux, via Gtk The Gtk implementation should also be usable on other Unix/X11 systems, or on Windows, if suitable libraries are installed. Download from here, or read the documentation online: http://www.cosc.canterbury.ac.nz/~greg/python_gui/ Note: This version is not quite complete yet; support for images is missing, and a few classes remain to be documented. I expect to remedy these things soon. Greg Ewing greg(a)cosc.canterbury.ac.nz

ZODB 3.2.2 beta 1 released
by Tim Peters 11 Jun '04

11 Jun '04

I'm pleased to announce the release of ZODB 3.2.2 beta 1. This is a bugfix release for the ZODB 3.2 line, and will be the version of ZODB released with Zope 2.7.1b2. The ZODB 3.2.2b1 release requires Python 2.3.3 or later. The ZODB 3.2 line supports Zope 2 only; Zope 3 requires ZODB 3.3. You can download a source tarball or Windows installer from: http://zope.org/Products/ZODB3.2 The changes since ZODB 3.2.1 consist of bugfixes, to BTrees, parts of ZODB proper, and support tools. See the news file for details: http://zope.org/Products/ZODB3.2/NEWS Important notes about Berkeley-based storages: Support for the experimental Berkeley-based storages has been dropped: they created more problems than the community has been able to fix, and nobody has done work on them for many months. Unfortunately, removing the code for BDBFullStorage and BDBMinimalStorage is also delicate, and it still exists in this release. We recommend not using it; the Berkeley code has already been removed from the ZODB 3.3 line. Note too that if you don't have "the right" version of Sleepycat Berkeley DB installed on your system, ZODB's test suite may fail-- or even segfault --as a result. This isn't an issue on Windows, because Python on Windows includes a suitable Sleepycat release (4.1.25). The problem appears most likely to occur on Linux systems with a bsddb from the later 4.2 line. While there's no resource to work on Berkeley problems, I'll at least try to disable the Berkeley tests for ZODB 3.2.2 final.

SC-Track Roundup 0.7.4 - an issue tracking system
by Richard Jones 11 Jun '04

11 Jun '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Roundup is a simple-to-use and -install issue-tracking system with command-line, web and e-mail interfaces. It is based on the winning design from Ka-Ping Yee in the Software Carpentry "Track" design competition. 0.7.4 is a bug fix release, including: - - re-acquire the OTK manager when we re-open the database - - mailgw handler can close the database on us - - fixed grouping by a NULL Link value - - fixed anydbm import/export (sf bugs 965216, 964457, 964450) - - fix python 2.3.3 strftime deprecation warning (sf patch 968398) - - fix some column datatypes in postgresql and mysql (sf bugs 962611, 959177 and 964231) - - fixed RDBMS journal packing (sf bug 959177) - - fixed filtering by floats in anydbm (sf bug 963584) - - fixed mysql upgrading of journals (sf bug 950410) If you're upgrading from an older version of Roundup you *must* follow the "Software Upgrade" guidelines given in the maintenance documentation. Roundup requires python 2.1.3 or later for correct operation. To give Roundup a try, just download (see below), unpack and run:: python demo.py Source and documentation is available at the website: http://roundup.sourceforge.net/ Release Info (via download page): http://sourceforge.net/projects/roundup Mailing lists - the place to ask questions: http://sourceforge.net/mail/?group_id=31577 About Roundup ============= Roundup manages a number of issues (with flexible properties such as "description", "priority", and so on) and provides the ability to: (a) submit new issues, (b) find and edit existing issues, and (c) discuss issues with other participants. The system will facilitate communication among the participants by managing discussions and notifying interested parties when issues are edited. One of the major design goals for Roundup that it be simple to get going. Roundup is therefore usable "out of the box" with any python 2.1+ installation. It doesn't even need to be "installed" to be operational, though a disutils-based install script is provided. It comes with two issue tracker templates (a classic bug/feature tracker and a minimal skeleton) and seven database back-ends (anydbm, bsddb, bsddb3, sqlite, metakit, mysql and postgresql). -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (GNU/Linux) iD8DBQFAyR3FrGisBEHG6TARAuA7AJ9NQWbNkfKfw/qnSBrjdvCtgvY51ACfZfBy IUbri/6bXheF9XN3gOrwfBQ= =EEkB -----END PGP SIGNATURE-----
