List traffic problems
by barry＠python.org Oct. 30, 2002

Oct. 30, 2002

Many people have noticed that traffic on this list has been uncharacteristically light for the last few weeks. We traced the problem to the news->mail gateway on python.org, however the problem appeared to be that the news server that python-list gateways /from/ was giving us just a trickle of messages per day. We've now got word from our ISP that their upstream newsfeed supposedly "forgot" about us -- they actually have no record that they were supposed to be giving our ISP a comp.lang.python feed. Hmm. In any event they say that our feed should be restored in 24-36 hours. Whether that means we'll get a flood of back postings or not isn't clear. Please keep an eye on the list traffic and see if things get back to normal over the next several days. If by next week your normal deluge of python-list isn't restored, let me know and I'll re-open the trouble ticket. -Barry

ANN: Leo 3.8 outlining editor
by Edward K. Ream Oct. 30, 2002

Oct. 30, 2002

leo.py 3.8 is now available at: http://sourceforge.net/projects/leo/ leo.py requires Python 2.1 or above and tcl/tk 8.3 or above. Major improvements have been made to Leo as the result of user requests. The highlights of 3.8: ---------------------- - New @rawfile and @silentfile trees complement @file trees. @rawfile and @silentfile trees create derived files without using sections. @rawfile files contain only those sentinels needed to automatically untangle them. @silentfile trees contain no sentinels at all. - New @raw and @end_raw directives allow unformatted code within @file trees. - Much better support for CWEB. You may organize .w files using noweb! - The @comment and @language directives may now apply simultaneously. - Leo can now read, remember and write <?xml-stylesheet...?> lines, under control of the new stylesheet option. - The new output_newline option specifies the line endings used when writing files. - The new output_initial_comment option specifies the text to appear in an @comment sentinel at the start of each derived file. - New commands in the help menu make it much easier to change configuration options. - Dozens of minor improvements and bug fixes. What is Leo? ------------ - A programmer's editor, an outlining editor and a flexible browser. - A literate programming tool, compatible with noweb and CWEB. - A data organizer and project manager. Leo provides multiple views of projects within a single outline. - Fully scriptable using Python. Leo saves its files in XML format. - Portable. leo.py is 100% pure Python. - Open Software, distributed under the Python License.

S.I.A.M. minisymposium on python and scientific simulation
by R. T. Pierrehumbert Oct. 28, 2002

Oct. 28, 2002

Mini-Symposium on Scientific Simulation in Python I am organizing a mini-symposium at the March 27-31 S.I.A.M. Dynamical Systems meeting (Snowbird) on the subject of use of Python for steering scientific simulations and for exploration of nonlinear dynamical systems. I will present an overview of the experience at our NSF-ITR center on use of Python in climate modelling, and have lined up additional speakers who are in the trenches on Python and simulation. I have slots available for up to four additional speakers, and am interested in hearing from others who are using Python in scientific simulations. If you think you might be interested, please send email describing your python-related work to me at rtp1(a)geosci.uchicago.edu. The abstract deadline is Nov. 26, so time is of the essence. For information on the U. of Chicago Python ITR, see geosci.uchicago.edu/~rtp1/itr Regards, Raymond T. Pierrehumbert Professor in Geophysical Sciences The University of Chicago

ZODB 3.1 / ZEO 2.0 released
by Jeremy Hylton Oct. 28, 2002

Oct. 28, 2002

I am pleased to announce the final releases of ZODB3 3.1 and ZEO 2.0! ZODB is an object database for Python that provides transactional persistence while requiring few, if any, changes to application logic. ZEO is a client-server storage system for ZODB. The ZEO package is released on its own and as part of ZODB3. The separate release is for Zope users, who already have ZODB. Source releases are available from: http://www.zope.org/Products/StandaloneZODB http://www.zope.org/Products/ZEO http://sourceforge.net/projects/zodb The ZODB3 release requires a C compiler, while the ZEO2 release is pure Python. Windows users can download a binary installer for Python 2.2.2 from: http://www.zope.org/Products/StandaloneZODB The components you get with the ZODB3 release are: - Core ZODB, including the persistence machinery - Standard storages such as FileStorage - Supporting modules such as ExtensionClass - The persistent BTrees modules - ZEO (versions 1 and 2) - Experimental Berkeley storages - Updated documentation The final release contains roughly the same version of ZODB that is available with Zope 2.6. The two releases are not directly coordinated, so there may be some minor differences. Many people have contributed to ZODB3. Special thanks to Toby Dickenson for the new ZODB Connection cache. Many people at Zope Corp. have contributed code and tested unreleased versions. There was only one change since the last beta release. A problem with unexpected exceptions in conflict resolution was fixed to allow transactions to fail more gracefully. (This change actually restored the pre-ZODB3 behavior.) Jeremy

ANN: PythonCard 0.6.9
by Kevin Altis Oct. 28, 2002

Oct. 28, 2002

PythonCard is a GUI construction kit for building cross-platform desktop applications on Windows, Mac OS X, and Linux. Release 0.6.9 includes over 30 sample applications and four tools to help users build applications in Python: codeEditor, findfiles, resourceEditor, and textEditor. A list of changes since release 0.6.8.1 is at the end of this message. All the information you need about PythonCard can be found on the project web page at: http://pythoncard.sourceforge.net/ The installation instructions and walkthroughs are available on the main documentation page: http://pythoncard.sourceforge.net/documentation.html Remember to backup or just delete your old PythonCardPrototype directory before installing a new version, so that the old files aren't still in the package directory. If you want to keep any of your userdata.txt or other configuration files (stc-styles.user.rc.cfg, pythoncard_user_config.py, etc.), back those up prior to doing the install, and then copy the files back afterwards. If you installed a previous version of PythonCard on Windows using the binary installer, then you should be able to remove the old package via the Add/Remove Programs Control Panel. The distutils installer will put the framework, components, docs, samples, and tools in Python22\Lib\site-packages. Of course, on Linux and Mac OS X that path will be slightly different and have forward slashes. You can download the latest release at: http://sourceforge.net/project/showfiles.php?group_id=19015 For a list of some of the samples that have been built with PythonCard and screenshots of them in action go to: http://pythoncard.sourceforge.net/samples.html A description of each sample is included in the readme.txt file in each sample directory. The kind people at SourceForge host the project: http://sourceforge.net/projects/pythoncard/ If you want to get involved the main contact point is the Mailing list: http://lists.sourceforge.net/lists/listinfo/pythoncard-users PythonCard requires Python 2.1.x (2.2.2 recommended) or later and wxPython 2.3.2.1 or later (2.3.3.1 recommended). wxPython can be downloaded at http://www.wxpython.org/ ka --- Kevin Altis altis(a)semi-retired.com --- changelog since release 0.6.8.1, 2002-07-17 Release 0.6.9 2002-10-23 added Thomas Heller's install-pythoncard.py script to create links under Windows added columnClick event to MultiColumnList added line and column display to statusbar in codeEditor added methods to graphic.Bitmap and BitmapCanvas classes to better support wxBimtap, wxImage and PIL updated webserver sample to run CGIs on Linux and Mac OS X; CGIs are no longer run as user 'nobody' added font utility functions to font.py module made resource argument optional for CustomDialog class added strings to dialog resources switched RadioGroup vertical and horizontal orientation added childWindow function to simplify loading windows added file_upload to webserver sample fixed label attribute in StaticBox Thomas Heller refactored the resourceEditor widget resizing runtime Property Editor fixes added jabberChat sample added code to disconnect wxEVT_KILL_FOCUS in WidgetDict to avoid hard crashes with wxPython 2.3.3 updated webserver.py with IE POST fixes and other Python lib changes added Robin Dunn's stattext.py and replacement StaticText component to the resourceEditor appcomponents fixed Scriptlets run code in textEditor to match codeEditor added dialog docs updated shell docs appled Tim Peters suggestions for sorting in flatfileDatabase for a roughly 5x sort time improvement added auto-rotation of images in pictureViewer and slideshow using EXIF.py and rotate90 method of the Bitmap class added EXIF.py by Gene Cash fixed typos in insertDialog.py scriptlet and scriptlet execution in textEditor fixed wxTAB_TRAVERSAL in panel switched back to a plain list in flatfileDatabase.py fixed missing webbrowser import in companies sample

A-A-P does more than make
by Bram Moolenaar Oct. 28, 2002

Oct. 28, 2002

A-A-P version 0.100 has been released. This is the first milestone for the A-A-P project. The main item in this release is the "aap" program. WHAT DOES THIS DO? The "aap" program is make on steroids. It does everything that make does, has a powerful script language build-in and has integrated internet support. You can use it to: - Build a program, on multiple platforms and in several variants - Maintain a web site (A-A-P is used for the Vim web site) - Download and install an application (like FreeBSD ports) - Obtain a module from CVS, update files in CVS - Generate and filter files Most of these things can be done with a recipe of just a few lines. Have a look at the examples: http://www.a-a-p.org/examples.html . The A-A-P recipe works better than a Makefile in many ways: - Uses signatures to avoid trouble with timestamps; restoring an old version of a file causes recompiling - Integrated support for up- and downloading - Integrated support for CVS (other version control systems can be added) - Python script can be used for more complicated tasks - Messages are brief, a log file contains the details - Reduces the need for shell scripts, improves portability - Automatically figures out dependencies for C programs - Simple syntax: mostly like a Makefile but avoids the need for line continuation backslashes, spaces in a file name are possible - Good support for a project with multiple directories A-A-P is written in Python. It currently runs on any Unix system with Python 1.5 or later. MS-Windows and Mac support is to be added later. WHAT IS A-A-P? A-A-P makes it easy to locate, download, build and install software. It also supports browsing source code, developing programs, managing different versions and distribution of software and documentation. This means that A-A-P is useful both for users and for developers. The current release is able to execute recipes. Further development will include an IDE framework, which makes it possible for existing tools to work together. For example: to use Vim with gdb for debugging, lookup remote documentation with the cross referencer, preview a TeX file, etc. A-A-P is still under development. Although the current version is working, not everything has been properly tested. There might be a few problems, use with care. A-A-P is open source under the GNU GPL. You are welcome to help improving A-A-P!

Sybase module 0.35pre2 released
by Dave Cole Oct. 28, 2002

Oct. 28, 2002

WHAT IS IT: The Sybase module provides a Python interface to the Sybase relational database system. It supports all of the Python Database API, version 2.0 with extensions. NOTES: In this release the module uses callback instead of inline error handling from the Sybase CT library. This has caused quite extensive changes to the threading support inside the low level extension module. One of the nice side effects of using callback error handling is that server errors while executing stored procedures will now be reported correctly. FreeTDS support is much improved in this version. You can build for FreeTDS like this: python setup.py build_ext -D HAVE_FREETDS -U WANT_BULKCOPY python setup.py install The module is available here: http://www.object-craft.com.au/projects/sybase/download/sybase-0.35pre2.tar… The module home page is here: http://www.object-craft.com.au/projects/sybase/ CHANGES SINCE 0.35pre1: * Changed ignored server messages to (5701, 5703). Thanks to Kevin Jacobs. * Allocate a new CS_COMMAND for each command executed on a cursor. This behaves like an explicit close() on the cursor in between commands. This makes it possible to perform multiple .execute() commands on a cursor with FreeTDS. * Added array binding to cursor to gain extra performance. Set the arraysize cursor attribute before executing a command. * Made connection locking optional. Sybase.connect(..., locking = 0) * Native DateTime types now has separate str() and repr(). print used to display "'11/01/63'". ARRAY BINDING: The following is a little test program to see the performance effect of array binding in the .fetchmany() cursor method. It looks like the speed was mostly going in function calls due to locking and single row fetching. run locking array functions time (ave 10 runs) test-array l Y N 88586 1.3248 secs test-array N N 20450 0.9803 secs test-array al Y Y 9458 0.5188 secs test-array a N Y 7262 0.5002 secs - - test-array.py - - - - - - - - - - - - - - - - - - - - - - - - import sys, Sybase def array_bind(): db = Sybase.connect('SYBASE', 'sa', '', 'sybsystemprocs', locking = do_locking) c = db.cursor() c.arraysize = 32 c.execute('select text from syscomments') num_rows = 0 while 1: rows = c.fetchmany() if not rows: break num_rows += len(rows) print num_rows, 'rows' def single_bind(): db = Sybase.connect('SYBASE', 'sa', '', 'sybsystemprocs', locking = do_locking) c = db.cursor() c.execute('select text from syscomments') num_rows = 0 while 1: row = c.fetchone() if not row: break num_rows += 1 print num_rows, 'rows' def main(): if do_array: array_bind() else: single_bind() do_profile = len(sys.argv) > 1 and sys.argv[1].find('p') >= 0 do_locking = len(sys.argv) > 1 and sys.argv[1].find('l') >= 0 do_array = len(sys.argv) > 1 and sys.argv[1].find('a') >= 0 if do_profile: import profile profile.run('main()') else: main() - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -- http://www.object-craft.com.au
