ANN: ConfigObj 4.0.0 Beta 4
by Fuzzyman 08 Sep '05

08 Sep '05

Hello Pythoneers, ConfigObj 4.0.0 has a beta 4 release. This fixes a couple of moderately serious bugs - so it's worth switching to. http://cheeseshop.python.org/pypi/ConfigObj http://www.voidspace.org.uk/python/configobj.html http://www.voidspace.org.uk/cgi-bin/voidspace/downman.py?file=configobj-4.0… http://sf.net/projects/configobj What's New ? ============ (Since Beta 2 the last announced version) 2005/09/07 ---------- Fixed bug in initialising ConfigObj from a ConfigObj. Changed the mailing list address. 2005/09/03 ---------- Fixed bug in ``Section__delitem__`` oops. 2005/08/28 ---------- Interpolation is switched off before writing out files. Fixed bug in handling ``StringIO`` instances. (Thanks to report from "Gustavo Niemeyer" <gustavo(a)niemeyer.net>) Moved the doctests from the ``__init__`` method to a separate function. (For the sake of IDE calltips). Beta 3 2005/08/26 ---------- String values unchanged by validation *aren't* reset. This preserves interpolation in string values. What is ConfigObj ? =================== ConfigObj is a simple but powerful config file reader and writer: an ini file round tripper. Its main feature is that it is very easy to use, with a straightforward programmer's interface and a simple syntax for config files. It has lots of other features though : * Nested sections (subsections), to any level * List values * Multiple line values * String interpolation (substitution) * Integrated with a powerful validation system o including automatic type checking/conversion o allowing default values o repeated sections * All comments in the file are preserved * The order of keys/sections is preserved * No external dependencies ConfigObj is available under the very liberal BSD License. It addresses *most* of the limitations of ConfigParser as discussed at : http://wiki.python.org/moin/ConfigParserShootout Anything Else ? =============== ConfigObj stores nested sections which map names to members (effectively dictionaries) with values as lists *or* single items. In association with the validate module it can transparently translate values back into booleans, floats, integers, and of course strings. This makes it ideal for *certain* types of human readable (and writable) data persistence. There is a discussion of this (with accompanying code) at : http://www.voidspace.org.uk/python/articles/configobj_for_data_persistence.…

Flightdeck-UI -- the Online Version
by George Belotsky 07 Sep '05

07 Sep '05

The Flightdeck-UI project now has a web-based version, Flightdeck-UI Online. See "http://www.openlight.com" for a live demo. What is Flightdeck-UI --------------------- The goal of the Flightdeck-UI project is to apply ideas from aircraft instrumentation design to general purpose user interfaces. The new web service has a plug-in architecture, and can simultaneously monitor multiple data sources (including hosts on the Internet as well as embedded devices) at different sampling rates. Also, virtually any Unix command that you enter from the shell can be automatically executed by Flightdeck-UI Online, and the results displayed by the system's virtual instruments. Although the web service requires a Flash front end (developed using only the MTASC open source ActionScript compiler; see http://www.mtasc.org/) Flightdeck-UI Online is still primarily written in Python. The author welcomes any ideas and suggestions: please email them directly to "python(a)openlight.com" Best Wishes, George Belotsky.

py2exe 0.6.2 released
by Thomas Heller 07 Sep '05

07 Sep '05

This is a bugfix release for py2exe 0.6.1. py2exe 0.6.2 released ===================== py2exe is a Python distutils extension which converts python scripts into executable windows programs, able to run without requiring a python installation. Console and Windows (GUI) applications, windows NT services, exe and dll COM servers are supported. Changes in 0.6.2: * Several important bugfixes: - bundled extensions in packages did not work correctly, this made the wxPython single-file sample fail with newer wxPython versions. - occasionally dlls/pyds were loaded twice, with very strange effects. - the source distribution was not complete. - it is now possible to build a debug version of py2exe. Changes in 0.6.1: * py2exe can now bundle binary extensions and dlls into the library-archive or the executable itself. This allows to finally build real single-file executables. The bundled dlls and pyds are loaded at runtime by some special code that emulates the Windows LoadLibrary function - they are never unpacked to the file system. This part of the code is distributed under the MPL 1.1, so this license is now pulled in by py2exe. * By default py2exe now includes the codecs module and the encodings package. * Several other fixes. Homepage: <http://starship.python.net/crew/theller/py2exe> Download from the usual location: <http://sourceforge.net/project/showfiles.php?group_id=15583> Enjoy, Thomas

by Aahz 07 Sep '05

07 Sep '05

DATE CHANGE: The next meeting of BayPIGgies will be Thurs, September 15 at 7:30pm at Google. We still don't have a room at Google; Paul Marxhausen has accepted the task of pinging people, but we may need to switch to Ironport if we don't get a room by Tuesday. Agenda has not been finalized -- we've got several topics and are juggling them. Stay tuned! BayPIGgies meetings alternate between IronPort (San Bruno, California) and Google (Mountain View, California). For more information and directions, see http://www.baypiggies.net/ Before the meeting, we plan to meet at 6pm for dinner. Discussion of dinner plans is handled on the BayPIGgies mailing list. Advance notice: The October 13 meeting agenda has been set. Please send e-mail to baypiggies(a)baypiggies.net if you want to suggest an agenda (or volunteer to give a presentation). We've got some options on the plate for November but haven't settled anything yet. -- Aahz (aahz(a)pythoncraft.com) <*> http://www.pythoncraft.com/ The way to build large Python applications is to componentize and loosely-couple the hell out of everything.

PyGreSQL 3.7 released
by D'Arcy J.M. Cain 07 Sep '05

07 Sep '05

Announce: Release of PyGreSQL version 3.7 =========================================== PyGreSQL v3.7 has been released. It is available at: ftp://ftp.druid.net/pub/distrib/PyGreSQL-3.7.tgz. If you are running NetBSD, look in the packages directory under databases. There is also a package in the FreeBSD ports collection. >From March 1 2001 the PyGreSQL development has moved into the PostgreSQL development tree. Starting with the 3.3 release it has been moved back to a separate project. PostgreSQL is a database system derived from Postgres4.2. It conforms to (most of) ANSI SQL and offers many interesting capabilities (C dynamic linking for functions or type definition, etc.). This package is copyright by the Regents of the University of California, and is freely distributable. Python is an interpreted programming language. It is object oriented, simple to use (light syntax, simple and straightforward statements), and has many extensions for building GUIs, interfacing with WWW, etc. An intelligent web browser (HotJava like) is currently under development (November 1995), and this should open programmers many doors. Python is copyrighted by Stichting S Mathematisch Centrum, Amsterdam, The Netherlands, and is freely distributable. PyGreSQL is a python module that interfaces to a PostgreSQL database. It embeds the PostgreSQL query library to allow easy use of the powerful PostgreSQL features from a Python script. PyGreSQL 2.0 was developed and tested on a NetBSD 1.3_BETA system. It is based on the PyGres95 code written by Pascal Andre, andre(a)chimay.via.ecp.fr. I changed the version to 2.0 and updated the code for Python 1.5 and PostgreSQL 6.2.1. While I was at it I upgraded the code to use full ANSI style prototypes and changed the order of arguments to connect. Later versions are fixes and enhancements to that. The latest version of PyGreSQL works with Python 1.5.2 and PostgreSQL 7.0.x Important changes from PyGreSQL 3.6.2 to PyGreSQL 3.7 - Fixes to quoting function. - Use Python datetime if mxDatetime is not available. - Add checks for valid database connection to methods. - Improved namespace support, handle search_path correctly. - Removed old dust and unnessesary imports, added docstrings. - Internal sql statements as one-liners, smoothed out ugly code. - Major improvements in classic pg module. Important changes from PyGreSQL 3.5 to PyGreSQL 3.6.2 - Further fixes to namespace handling Important changes from PyGreSQL 3.5 to PyGreSQL 3.6.1 - Fix namespace handling Important changes from PyGreSQL 3.5 to PyGreSQL 3.6 - Better DB-API 2.0 compliance - Exception hierarchy moved into C module and made available to both APIs - Fix error in update method that caused false exceptions - Moved to standard exception hierarchy in classic API - Added new method to get transaction state - Use proper Python constants where appropriate - Use Python versions of strtol, etc. Allows WIN32 build - Bug fixes and cleanups Important changes from PyGreSQL 3.4 to PyGreSQL 3.5 - Add interval to list of data types - fix up method wrapping especially close() - retry pkeys once if table missing in case it was just added - wrap query method separately to handle debug better - use isinstance instead of type - fix free/PQfreemem issue - finally Important changes from PyGreSQL 3.3 to PyGreSQL 3.4 - Moved back out of PostgreSQL tree - Allow for larger integer returns - Return proper strings for true and false - Cleanup convenience method creation - Enhance debugging method - Add reopen method - Allow programs to preload field names for speedup - Move OID handling so that it returns long instead of int - Miscellaneous cleanups and formatting Important changes from PyGreSQL 3.2 to PyGreSQL 3.3 - Added NUMERICOID to list of returned types. This fixes a bug when returning aggregates in the latest version of PostgreSQL. Important changes from PyGreSQL 3.1 to PyGreSQL 3.2 Note that there are very few changes to PostgreSQL between 3.1 and 3.2. The main reason for the release is the move into the PostgreSQL development tree. Even the WIN32 changes are pretty minor. - Add WIN32 support (gerhard(a)bigfoot.de) - Fix some DB-API quoting problems (niall.smart(a)ebeon.com) - Moved development into PostgreSQL development tree. Important changes from PyGreSQL 3.0 to PyGreSQL 3.1 - Fix some quoting functions. In particular handle NULLs better. - Use a method to add primary key information rather than direct manipulation of the class structures. - Break decimal out in _quote (in pg.py) and treat it as float. - Treat timestamp like date for quoting purposes. - Remove a redundant SELECT from the get method speeding it, and insert since it calls get, up a little. - Add test for BOOL type in typecast method to pgdbTypeCache class. (tv(a)beamnet.de) - Fix pgdb.py to send port as integer to lower level function (dildog(a)l0pht.com) - Change pg.py to speed up some operations - Allow updates on tables with no primary keys. Important changes from PyGreSQL 2.4 to PyGreSQL 3.0: - Remove strlen() call from pglarge_write() and get size from object. (Richard(a)Bouska.cz) - Add a little more error checking to the quote function in the wrapper - Add extra checking in _quote function - Wrap query in pg.py for debugging - Add DB-API 2.0 support to pgmodule.c (andre(a)via.ecp.fr) - Add DB-API 2.0 wrapper pgdb.py (andre(a)via.ecp.fr) - Correct keyword clash (temp) in tutorial - Clean up layout of tutorial - Return NULL values as None (rlawrence(a)lastfoot.com) (WARNING: This will cause backwards compatibility issues.) - Change None to NULL in insert and update - Change hash-bang lines to use /usr/bin/env - Clearing date should be blank (NULL) not TODAY - Quote backslashes in strings in _quote (brian(a)CSUA.Berkeley.EDU) - Expanded and clarified build instructions (tbryan(a)starship.python.net) - Make code thread safe (Jerome.Alet(a)unice.fr) - Add README.distutils (mwa(a)gate.net & jeremy(a)cnri.reston.va.us) - Many fixes and increased DB-API compliance by chifungfan(a)yahoo.com, tony(a)printra.net, jeremy(a)alum.mit.edu and others to get the final version ready to release. Important changes from PyGreSQL 2.3 to PyGreSQL 2.4: - Insert returns None if the user doesn't have select permissions on the table. It can (and does) happen that one has insert but not select permissions on a table. - Added ntuples() method to query object (brit(a)druid.net) - Corrected a bug related to getresult() and the money type - Corrected a bug related to negative money amounts - Allow update based on primary key if munged oid not available and table has a primary key - Add many __doc__ strings. (andre(a)via.ecp.fr) - Get method works with views if key specified Important changes from PyGreSQL 2.2 to PyGreSQL 2.3: - connect.host returns "localhost" when connected to Unix socket (torppa(a)tuhnu.cutery.fi) - Use PyArg_ParseTupleAndKeywords in connect() (torppa(a)tuhnu.cutery.fi) - fixes and cleanups (torppa(a)tuhnu.cutery.fi) - Fixed memory leak in dictresult() (terekhov(a)emc.com) - Deprecated pgext.py - functionality now in pg.py - More cleanups to the tutorial - Added fileno() method - terekhov(a)emc.com (Mikhail Terekhov) - added money type to quoting function - Compiles cleanly with more warnings turned on - Returns PostgreSQL error message on error - Init accepts keywords (Jarkko Torppa) - Convenience functions can be overridden (Jarkko Torppa) - added close() method Important changes from PyGreSQL 2.1 to PyGreSQL 2.2: - Added user and password support thanks to Ng Pheng Siong <ngps(a)post1.com> - Insert queries return the inserted oid - Add new pg wrapper (C module renamed to _pg) - Wrapped database connection in a class. - Cleaned up some of the tutorial. (More work needed.) - Added version and __version__. Thanks to thilo(a)eevolute.com for the suggestion. Important changes from PyGreSQL 2.0 to PyGreSQL 2.1: - return fields as proper Python objects for field type - Cleaned up pgext.py - Added dictresult method Important changes from Pygres95 1.0b to PyGreSQL 2.0: - Updated code for PostgreSQL 6.2.1 and Python 1.5. - Reformatted code and converted to ANSI . - Changed name to PyGreSQL (from PyGres95.) - Changed order of arguments to connect function. - Created new type pgqueryobject and moved certain methods to it. - Added a print function for pgqueryobject - Various code changes - mostly stylistic.

by Jacob Smullyan 06 Sep '05

06 Sep '05

I'm pleased to announce the release of PyDO-2.0b2. What's New ---------- * the project() method now takes the keyword argument "mutable", which overrides the mutability of the base class. * new, more declarativeshortcuts for defining associations between tables: ForeignKey, OneToMany, and ManyToMany. * several bugfixes, with corresponding tests. What it is ---------- PyDO is Drew Csillag's ORM (Object-Relational Mapper) database access library for Python that facilitates writing a Python database access layer. PyDO attempts to be simple, flexible, extensible, and unconstraining. PyDO 2 is a rewrite of the 1.x series distributed with SkunkWeb. It has several enhancements: * PyDO can now be used in multi-threaded or twisted-style asynchronous sitations, with or without a customizable connection pool. * PyDO objects are now dict subclasses, but also support attribute access to fields. * Projections -- subsets of the field list of a super-class -- are now supported by the PyDO.project() method. * Table attributes are now declared in a more concise way. * PyDO2 supports runtime table introspection. * Overall, the API has been tightened and the code restructured. PyDO 2 requires Python 2.4 or later. It currently supports PostgreSQL, MySQL, Sqlite, MSSQL, and Oracle, and support for other databases is planned. PyDO is dual GPL/BSD licensed. The source tarball is available at SkunkWeb's berlios site: https://developer.berlios.de/projects/skunkweb/ or, more directly: http://download.berlios.de/skunkweb/PyDO-2.0b2.tar.gz Questions pertaining to PyDO can be addressed to the SkunkWeb mailing list at sourceforge: http://lists.sourceforge.net/lists/listinfo/skunkweb-list Cheers, js -- Jacob Smullyan

what is it ---------- A simple Server which enables tests of Python regular expressions (re module) in a webbrowser. Uses SimpleHTTPServer and AJAX. You need: Python, a modern webbrowser like Firefox, IE (from 5.5), Safari or Opera (from 8) which handles XMLHttpRequests. license ------- This work is licensed under a Creative Commons License. download -------- current version: retest-0.4.zip - 050906, from http://cthedot.de/retest/ Tested with Python 2.4.1, Firefox 1.06, Internet Explorer 6 and Opera 8.02 on Windows XP only. Seems to work best with Firefox and Opera, any feedback (success or failure ;) is welcome. usage ----- Start the server with >python reserver.py and open http://localhost:8087/ in your webbrowser. You might want to adjust the PORT used in reserver.py. The usage of the application itself should be self explanatory, take a look in the Python documentation for the re module. any comment will be appreciated, thanks christof hoeke <P><A HREF="http://cthedot.de/retest/">retest 0.4</A> - test Python regular expressions in a webbrowser (06-Sep-05)

ANNOUNCE: PyGTK 2.6.3
by Johan Dahlin 06 Sep '05

06 Sep '05

I am pleased to announce version 2.6.3 of the Python bindings for GTK. The new release is available from ftp.gnome.org as and its mirrors as soon as its synced correctly: http://ftp.gnome.org/pub/GNOME/sources/pygtk/2.6/pygtk-2.6.3.tar.gz Changes since 2.6.2: - gtk.TreeView.map_extended_row refcount fix (Tim Evans, Gustavo) - win32 build fix (Cedric Gustin) - Allow fundamental types to be registered (Edward Hervey) Blurb: GTK is a toolkit for developing graphical applications that run on POSIX systems such as Linux, Windows and MacOS X (provided that the X server for MacOS X has been installed). It provides a comprehensive set of GUI widgets, can display Unicode bidi text. It links into the Gnome Accessibility Framework through the ATK library. PyGTK provides a convenient wrapper for the GTK+ library for use in Python programs, and takes care of many of the boring details such as managing memory and type casting. When combined with PyORBit and gnome-python, it can be used to write full featured Gnome applications. Like the GTK+ library itself PyGTK is licensed under the GNU LGPL, so is suitable for use in both free software and proprietary applications. It is already in use in many applications ranging from small single purpose scripts up to large full features applications. PyGTK requires GTK+ >= 2.6 and Python >= 2.3 to build. Bug reports, as always, should go to Bugzilla; check out http://pygtk.org/developer.html and http://pygtk.org/feedback.html for links to posting and querying bug reports for PyGTK. -- Johan Dahlin johan(a)gnome.org
