Setuptools 0.6c11 released
by P.J. Eby 20 Oct '09

20 Oct '09

Oops! ----- Due to a couple of last-minute issues with the 0.6c10 release, I've released an 0.6c11 update at: http://pypi.python.org/setuptools/ It fixes an error when running the "sdist" command on a package with no README, and includes the 64-bit Windows fix that was promised in 0.6c10 but wasn't actually checked in to SVN. You can install the updated version using easy_install (or pip!), by asking for setuptools==0.6c11. The Fine Print -------------- (Note for users of Distribute: Distribute and setuptools use the same package name 'setuptools', and thus cannot both be present on the same sys.path (e.g. in the same virtualenv). If you wish to switch a given environment from Distribute to setuptools or vice versa, you will need to completely uninstall one before installing the other. If you currently have Distribute installed, please follow Distribute's uninstall instructions if you wish to reinstall setuptools.) Please report any bugs to the setuptools bug tracker at: http://bugs.python.org/setuptools/ For faster response to questions, please use the distutils-sig mailing list, rather than the tracker. Setuptools documentation can be found via links at http://pypi.python.org/pypi/setuptools#using-setuptools-and-easyinstall -- and the pages on the PEAK wiki now load much, much faster than they did a few months ago. (They're static cached pages now, rather than dynamically generated, unless you're actually logged into the wiki.)

SQLObject 0.12.0
by Oleg Broytman 20 Oct '09

20 Oct '09

Hello! I'm pleased to announce version 0.12.0, the first stable release of branch 0.12 of SQLObject. What is SQLObject ================= SQLObject is an object-relational mapper. Your database tables are described as classes, and rows are instances of those classes. SQLObject is meant to be easy to use and quick to get started with. SQLObject supports a number of backends: MySQL, PostgreSQL, SQLite, Firebird, Sybase, MSSQL and MaxDB (also known as SAPDB). Where is SQLObject ================== Site: http://sqlobject.org Development: http://sqlobject.org/devel/ Mailing list: https://lists.sourceforge.net/mailman/listinfo/sqlobject-discuss Archives: http://news.gmane.org/gmane.comp.python.sqlobject Download: http://cheeseshop.python.org/pypi/SQLObject/0.12.0 News and changes: http://sqlobject.org/News.html What's New ========== Features & Interface -------------------- * .selectBy(), .deleteBy() and .by*() methods pass all values through .from_python(), not only unicode. * The user can choose a DB API driver for SQLite by using a "backend" parameter in DB URI or SQLiteConnection that can be a comma-separated list of backend names. Possible backends are: "pysqlite2" (alias "sqlite2"), "sqlite3", "sqlite" (alias "sqlite1"). Default is to test pysqlite2, sqlite3 and sqlite in that order. * The user can choose a DB API driver for PostgreSQL by using a "backend" parameter in DB URI or PostgresConnection that can be a comma-separated list of backend names. Possible backends are: "psycopg2", "psycopg1", "psycopg" (tries psycopg2 and psycopg1), "pygresql". Default is "psycopg". WARNING: API change! PostgresConnection's parameter "usePygresql" is now replaced with "backend=pygresql". * The user can choose a DB API driver for MSSQL by using a "backend" parameter in DB URI or MSSQLConnection that can be a comma-separated list of backend names. Possible backends are: "adodb" (alias "adodbapi") and "pymssql". Default is to test adodbapi and pymssql in that order. * alternateMethodName is defined for all unique fields, not only alternateID; this makes SQLObject create .by*() methods for all unique fields. * SET client_encoding for PostgreSQL to the value of "charset" parameter in DB URI or PostgresConnection. * TimestampCol() can be instantiated without any defaults, in this case default will be None (good default for TIMESTAMP columns in MySQL). Small Features -------------- * Imported DB API drivers are stored as connection instance variables, not in global variables; this allows to use different DB API drivers at the same time; for example, PySQLite2 and sqlite3. * Removed all deprecated attribute and functions. * Removed the last remained string exceptions. For a more complete list, please see the news: http://sqlobject.org/News.html Oleg. -- Oleg Broytman http://phd.pp.ru/ phd(a)phd.pp.ru Programmers don't die, they just GOSUB without RETURN.

Setuptools 0.6c10 released
by P.J. Eby 19 Oct '09

19 Oct '09

The long-overdue setuptools 0.6c10 update is now available on PyPI, at: http://pypi.python.org/setuptools/ Major updates and fixes include: * Support for SVN 1.6 and Python 2.6 * Fix for the Python 2.6.3 build_ext API change * Support for the most recent Sourceforge download link insanity * Fix for Vista UAC errors running easy_install.exe or other "installer-looking" executables * Fix for errors launching 64-bit Windows Python * Stop crashing on certain types of HTTP error * Stop re-trying URLs that already failed retrieval once * Fixes for various dependency management problems such as looping builds, re-downloading packages already present on sys.path (but not in a registered "site" directory), and randomly preferring local -f packages over local installed packages * Prevent lots of spurious "already imported from another path" warnings (e.g. when pkg_resources is imported late) * Ensure C libraries (as opposed to extensions) are also built when doing bdist_egg Other changes: * Misc. documentation fixes * Improved Jython support * Fewer warnings under Python 2.6+ * Warn when 'packages' uses paths instead of package names (because it causes other problems, like spurious "already imported" warnings) * Stop using /usr/bin/sw_vers on Mac OS (replaced w/'platform' module calls) You can install the updated version using easy_install (or pip!), asking for setuptools==0.6c10. (Note for users of Distribute: Distribute and setuptools use the same package name 'setuptools', and thus cannot both be present on the same sys.path (e.g. in the same virtualenv). If you wish to switch a given environment from Distribute to setuptools or vice versa, you will need to completely uninstall one before installing the other. If you currently have Distribute installed, please follow Distribute's uninstall instructions if you wish to reinstall setuptools.)

APSW 3.6.19-r1 released (Another Python SQLite Wrapper)
by Roger Binns 17 Oct '09

17 Oct '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 APSW 3.6.19-r1 is now available. The home page is at http://code.google.com/p/apsw/ which includes full documentation, source and binary distributions for Windows (Python 2.3 onwards including 3.0 & 3.1). APSW is a wrapper around SQLite that provides all SQLite API functionality in Python. It is not DBAPI compliant as it provides SQLite semantics. pysqlite provides DBAPI semantics. You can see the two approaches contrasted at http://apsw.googlecode.com/svn/publish/pysqlite.html Changelist is below and a clickable version at http://apsw.googlecode.com/svn/publish/changes.html Backwards incompatible change: Fixed issue 72 where APSW wasn’t zero basing virtual table BestIndex() constraints returned as documented. If you have working BestIndex code then you need to update it for this release. Thanks to Lefteris for finding this issue. Backwards incompatible change: The complete() method has moved from Connection to apsw where it should have been all along. You should now call apsw.complete() instead. (It even had an example showing it to be part of the module and not a specific connection!) There is now an interactive shell very similar to that provided by SQLite. You can embed it in your own program, inherit from it to provide more commands and output modes, or just run it like this: $ python -c "import apsw ; apsw.main()" Added the SQLITE_LIMIT_TRIGGER_DEPTH, SQLITE_OPEN_PRIVATECACHE and SQLITE_OPEN_SHAREDCACHE constants. The setup.py file now has the various options available made applicable to appropriate commands only. Read the updated documentation. You can now specify build --enable=stat2 to setup.py to enable advanced statistics gathering for query planning. setup.py can automatically fetch the Asynchronous VFS extension for you. If the source is present when APSW is built then it will be automatically included and the API provided. A fork_checker() is available which turns on detection when you have used SQLite objects across a fork (a very bad thing). This is possible on Unix like operating systems, especially if you use the multiprocessing module. Extension loading is now compiled in by default when using the amalgamation and compiled out when using existing libraries. This is more likely to match your machine. You can use --omit=load_extension or --enable=load_extension to the build/build_ext commands to explicitly disable/enable extension loading. (Issue 67). setup.py will now abort on a download that has no checksum. See more information on checksums in the documentation. setup.py can also fetch the version of SQLite currently under development before a release. Use --version=fossil. Updated which code uses experimental SQLite APIs based on changes in SQLite. The test suite will also work correctly with experimental on or off. (It is on by default.)

rst2pdf version 0.12.1 released
by Roberto Alsina 14 Oct '09

14 Oct '09

I just uploaded rst2pdf 0.12.1 to http://rst2pdf.googlecode.com This release has no new features, just some bugs fixed. If you had problems with previous releases, this could be a good one to try ;-) For more details, see the changelog: http://code.google.com/p/rst2pdf/source/browse/branches/0.12/CHANGES.txt Rst2pdf is a tool to generate PDF files directly from restructured text sources via reportlab. Rst2pdf aims to support the full restructured text feature set, and is very close to that goal, while also including some of the more experimental features, like a source code directive with syntax highlighting and math notation support with LaTeX-like syntax. It supports embedding arbitrary fonts, both True Type and PS Type 1, both raster and vector images (including SVG and PDF), page transition effects, multiple, flexible page layouts, cascading styles, and much, much more.
