[ANN] SQLObject 0.6.1
by Ian Bicking Jan. 26, 2005

Jan. 26, 2005

SQLObject 0.6.1 --------------- Version 0.6.1 is a bug fix release for 0.6. Most of the work on this release has been thanks to the contributions of Oleg Broytmann. Thanks Oleg! A brief list of changes: * All class methods take a connection argument. * "DISTINCT" option for select results. * Connection objects have a new module attribute, to get access to the connection's exceptions. * New UnicodeCol() for encoding and decoding values from the database. * Added Indexing (patch from Jeremy Fitzhardinge). * Database connections explicitly closed, instead of just letting them be garbage collected. * selectBy can take be called with instances instead of only IDs for foreign key columns. * DBMConnection was removed (it's been broken a long time). What Is SQLObject? ------------------ SQLObject is an Object-Relational Mapper. Basically it makes your database rows feel like (relatively) normal Python objects: Tables are classes, rows are instances, columns are attributes. SQLObject both allows you to define your classes in Python, and SQLObject will create the tables on your behalf, or SQLObject may use database reflection to dynamically create a class given a table name. SQLObject portably supports a variety of database backends: MySQL, PostgreSQL, SQLite, Firebird, MaxDB/SAPDB, and SyBase. SQLObject is being used in a variety of external projects: ezSQLObject, sqlo for Zope 3, and Subway (a Ruby on Rails clone), among others. Where Is SQLObject? ------------------- Website: http://sqlobject.org News: http://sqlobject.org/docs/News.html#sqlobject-0-6-1 Documentation: http://sqlobject.org/docs/SQLObject.html Subversion repository: http://svn.colorstudy.com/trunk/SQLObject Mailing list: http://lists.sourceforge.net/mailman/listinfo/sqlobject-discuss Archives: http://dir.gmane.org/gmane.comp.python.sqlobject Download: http://prdownloads.sourceforge.net/sqlobject/SQLObject-0.6.1.tar.gz?download -- Ian Bicking / ianb(a)colorstudy.com / http://blog.ianbicking.org

[ANN] Python Spread Module 1.5 final released
by Tim Peters Jan. 25, 2005

Jan. 25, 2005

Release 1.5 (final) of the Spread Module for Python is now available: http://zope.org/Members/tim_one/spread No changes have been made since last week's 1.5 beta 1 release. The primary visible changes since release 1.4 are Mark McClain's new code to give Mailbox objects a multigroup_multicast() method, and that the Windows build now works with Spread 3.17.3. See the download page for details. About the Spread Module ----------------------- This package contains a simple Python wrapper module for the Spread toolkit (see below). It wraps Spread mailboxes and messages in Python objects with appropriate methods and attributes, and turns Spread errors into Python exceptions. Virtually all Spread features are accessible from Python. It's intended to be used with Spread 3.17.3 and Python 2.3.4, although other combinations are possible. A source tarball is available, and a Windows installer with a precompiled spread.pyd (which must be used with a Python in the 2.3 line). About Spread ------------ >From the Spread website (<http://www.spread.org>): Spread is a toolkit that provides a high performance messaging service that is resilient to faults across external or internal networks. Spread functions as a unified message bus for distributed applications, and provides highly tuned application-level multicast and group communication support. Spread services range from reliable message passing to fully ordered messages with delivery guarantees, even in case of computer failures and network partitions. Spread is designed to encapsulate the challenging aspects of asynchronous networks and enable the construction of scalable distributed applications, allowing application builders to focus on the differentiating components of their application.

cx_Oracle 4.1
by Anthony Tuininga Jan. 24, 2005

Jan. 24, 2005

What is cx_Oracle? cx_Oracle is a Python extension module that allows access to Oracle and conforms to the Python database API 2.0 specifications with a few exceptions. Where do I get it? http://starship.python.net/crew/atuining What's new? 1) Added support for Python 2.4. In Python 2.4, the datetime module is used for both binding and fetching of date and timestamp data. In Python 2.3, objects from the datetime module can be bound but the internal datetime objects will be returned from queries. 2) Added pickling support for LOB and datetime data. 3) Fully qualified the table name that was missing in an alter table statement in the setup test script as noted by Marc Gehling. 4) Added a section allowing for the setting of the RPATH linker directive in setup.py as requested by Iustin Pop. 5) Added code to raise a programming error exception when an attempt is made to access a LOB locator variable in a subsequent fetch. 6) The username, password and dsn (tnsentry) are stored on the connection object when specified, regardless of whether or not a standard connection takes place. 7) Added additional module level constant called "LOB" as requested by Joseph Canedo. 8) Changed exception type to IntegrityError for constraint violations as requested by Joseph Canedo. 9) If scale and precision are not specified, an attempt is made to return a long integer as requested by Joseph Canedo. 10) Added workaround for Oracle bug which returns an invalid handle when the prepare call fails. Thanks to alantam(a)hsbc.com for providing the code that demonstrated the problem. 11) The cusor method arravar() will now accept the actual list so that it is not necessary to call cursor.arrayvar() followed immediately by var.setvalue(). 12) Fixed bug where attempts to execute the statement "None" with bind variables would cause a segmentation fault. 13) Added support for binding by position (paramstyle = "numeric"). 14) Removed memory leak created by calls to OCIParamGet() which were not mirrored by calls to OCIDescriptorFree(). Thanks to Mihai Ibanescu for pointing this out and providing a patch. 15) Added support for calling cursor.executemany() with statement None implying that the previously prepared statement ought to be executed. Thanks to Mihai Ibanescu for providing a patch. 16) Added support for rebinding variables when a subsequent call to cursor.executemany() uses a different number of rows. Thanks to Mihai Ibanescu for supplying a patch. 17) The microseconds are now displayed in datetime variables when nonzero similar to method used in the datetime module. 18) Added support for binary_float and binary_double columns in Oracle 10g. Changes since 4.1 beta 1 1) Fixed bug where subclasses of Cursor do not pass the connection in the constructor causing a segfault. 2) DDL statements must be reparsed before execution as noted by Mihai Ibanescu. 3) Add support for setting input sizes by position. 4) Fixed problem with catching an exception during execute and then still attempting to perform a fetch afterwards as noted by Leith Parkin. 5) Rename the types so that they can be pickled and unpickled. Thanks to Harri Pasanen for pointing out the problem. 6) Handle invalid NLS_LANG setting properly (Oracle seems to like to provide a handle back even though it is invalid) and determine the number of bytes per character in order to allow for proper support in the future of multibyte and variable width character sets. 7) Remove date checking from the native case since Python already checks that dates are valid; enhance error message when invalid dates are encountered so that additional processing can be done. 8) Fix bug executing SQL using numeric parameter names with predefined variables (such as what takes place when calling stored procedures with out parameters). 9) Add support for reading CLOB values using multibyte or variable length character sets. -- Anthony Tuininga anthony(a)computronix.com Computronix Distinctive Software.

ANN: Leo 4.3-a1 released
by Edward K. Ream Jan. 24, 2005

Jan. 24, 2005

Leo 4.3 alpha 1 is now available at http://sourceforge.net/projects/leo/ Leo 4.3 is the culmination of more than four months of work. In spite of its alpha status, I recommend Leo 4.3a1 over any 4.2 release. The defining features of Leo 4.3: --------------------------------- 1. Leo now stores options in @settings trees, that is, outlines whose headline is '@settings'. When opening a .leo file, Leo looks for @settings trees not only in the outline being opened but also in various leoSettings.leo files. The key design goal of @settings trees was that Leo's user options must be infinitely flexible. That goal has been accomplished. Indeed, users can create arbitrarily complex user options with @settings trees. Leo settings outlines are, in fact, infinitely more flexible and powerful than any scheme based on flat text. Readers of Python's configParser shootout take note. 2. The Preferences command temporarily replaces the outline pane with an outline showing all the @settings trees in effect. The Preferences command also replaces the body pane with a "settings pane". This settings pane allows you to change the settings selected in the outline pane using standard gui widgets. The settings pane is dynamically created from nodes in the settings tree; it is as extensible as the @settings tree itself. 3. Leo's read/write code in leoAtFile.py has been rewritten to support user-defined tangling and untangling. This is a major cleanup of Leo's core. 4. Leo now boasts a wonderful new Plugins Manager plugin. This plugin enables and disables plugins automatically. You never have to mess with pluginsManager.txt again. This plugin also tells you everything you need to know about each plugin. Finally, this plugin also lets you download plugins from Leo's cvs site. 5. You can install third-party extensions in Leo's extensions directory. Leo will attempt to import such extensions from the extensions directory if normal imports fail. As usual, version 4.3 contains many other improvements and bug fixes. What people are saying about Leo -------------------------------- "I am using Leo since a few weeks and I brim over with enthusiasm for it. I think it is the most amazing software since the invention of the spreadsheet." -- juergen_r "We who use Leo know that it is a breakthrough tool and a whole new way of writing code." -- Joe Orr "I am a huge fan of Leo. I think it's quite possibly the most revolutionary programming tool I have ever used and it (along with the Python language) has utterly changed my view of programming (indeed of writing) forever." -- Shakeeb Alireza "Thank you very much for Leo. I think my way of working with data will change forever...I am certain [Leo] will be a revolution. The revolution is as important as the change from sequential linear organization of a book into a web-like hyperlinked pages. The main concept that impress me is that the source listing isn't the main focus any more. You focus on the non-linear, hierarchical, collapsible outline of the source code." -- Korakot Chaovavanich "Leo is a quantum leap for me in terms of how many projects I can manage and how much information I can find and organize and store in a useful way." -- Dan Winkler "Wow, wow, and wow...I finally understand how to use clones and I realized that this is exactly how I want to organize my information. Multiple views on my data, fully interlinkable just like my thoughts." -- Anon. "A few years back I would have said Zope was #1 Python showcase, but I agree 100% that Leo is tops now." -- Jason Cunliffe "Leo is the most interesting Python project I know of...I see lots of stuff posted on the Daily Python page, but I usually yawn and come over to this forum to see what's cooking." -- Anon More quotes at: http://webpages.charter.net/edreamleo/testimonials.html What makes Leo special? ----------------------- - Leo's outlines add a new dimension to programming. - Leo shows you your code and data the way _you_ want to see them. - Leo extends, completes and simplifies literate programming. - Leo's script buttons bring scripts to data. 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. Leo requires Python 2.2.1 or above and tcl/tk 8.4 or above. Leo works on Linux, Windows and MacOs X.

Leo 4.2.1 final released
by Edward K. Ream Jan. 24, 2005

Jan. 24, 2005

Leo 4.2.1 Final is now available at http://sourceforge.net/projects/leo/ Version 4.2.1 corrects problems associated with Python 2.4: - Leo's Pretty Print command was broken by the new use of '@' in Python 2.4. - Leo's installer was broken by the new installer used in Python 2.4. This will likely be the last 4.2.x release of Leo. Leo 4.3 alpha 1 will be released shortly. In spite of its name, 4.3 alpha 1 should be solid enough for most people. Besides version numbers and readme files, there have been no changes made between 4.2.1 beta 1 and 4.2.1 final. Highlights of version 4.2: ------------------------- - @thin trees make Leo much more friendly to cvs. - Leo's data structures have been reorganized to make outline operations significantly faster. All old scripts still work. - @test and @script nodes convert scripts to unit tests automatically. You can convert scripts to unit tests in seconds! - A faster and more robust spell checker plugin. (requires Python 2.3) - Leo is now much more friendly to using spaces instead of tabs. - The Execute Script command reports erroneous lines more clearly. - Leo draws large outlines more quickly using less memory. - Dozens of other improvements. 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.

[ANN] PyComicsViewer 0.9.4
by ionutz Jan. 24, 2005

Jan. 24, 2005

PyComicsViewer-0.9.4 has been released. What is PyComicsViewer? ======================= Is a comics viewer written in python, PyGTK and PIL. I made it as I didn't fully like any of the existing viewers and I wanted something that works the same (nice) way on both Linux and Windows. Because of the way it was implemented, you can also use it like a kind of image browser/viewer, but this is not its primary destination. Browsing images from uncompressed directories is provided because resulted naturally from the implementation and because I've seen some people that distribute their scaned comics uncompressed. Changes in 0.9.4 (2005/01/24) ============================= * added distutils support * added a LICENSE file * alternate C rotation implementations for GdkStrategy * solved restauration of the initial size and position even when the viewer is closed when maximized or in fullscreen * pulse the progress during decompresion * display some text info during scanning the dir * refresh doesn't reset the current page * new stock icons and app icon * added code for the '...' buttons from the preferences dialog Licensing ========= PyComicsViewer is released under the GPL. Where can I get it? =================== You can download it from: http://borco.net/html/PyComicsViewer/ Cheers,
