Elixir 0.4.0 released!
by Gaetan de Menten 29 Oct '07

29 Oct '07

I am very pleased to announce that version 0.4.0 of Elixir is now available. As always, feedback is very welcome, preferably on Elixir mailing list. Highlights for this release ------------------------------------- - Implemented a new attribute-based syntax to declare fields and relationships, which is much closer to what is found in other Python ORM's. - Full support for SQLAlchemy 0.4 - Implemented polymorphic single-table inheritance as well as polymorphic and non-polymorphic multi-table (aka joined table) inheritance. - Added versioning extension to keep track to all changes to your entities by storing them in a secondary table. - Extended documentation (tutorial and others). Please see http://elixir.ematia.de/trac/wiki/Migrate03to04 for detailed upgrade notes. The full list of changes can be seen at: http://elixir.ematia.de/trac/browser/elixir/tags/0.4.0/CHANGES What is Elixir? --------------------- Elixir is a declarative layer on top of the SQLAlchemy library. It is a fairly thin wrapper, which provides the ability to create simple Python classes that map directly to relational database tables (this pattern is often referred to as the Active Record design pattern), providing many of the benefits of traditional databases without losing the convenience of Python objects. Elixir is intended to replace the ActiveMapper SQLAlchemy extension, and the TurboEntity project but does not intend to replace SQLAlchemy's core features, and instead focuses on providing a simpler syntax for defining model objects when you do not need the full expressiveness of SQLAlchemy's manual mapper definitions.

ANN: Veusz 1.0 - a scientific plotting package
by Jeremy Sanders 29 Oct '07

29 Oct '07

I'm pleased to announce Veusz 1.0. Source, windows and linux i386 binaries are available - Jeremy Sanders Veusz 1.0 --------- Velvet Ember Under Sky Zenith ----------------------------- http://home.gna.org/veusz/ Veusz is Copyright (C) 2003-2007 Jeremy Sanders <jeremy(a)jeremysanders.net> Licenced under the GPL (version 2 or greater). Veusz is a scientific plotting package written in Python, using PyQt4 for display and user-interfaces, and numpy for handling the numeric data. Veusz is designed to produce publication-ready Postscript/PDF output. The user interface aims to be simple, consistent and powerful. Veusz provides a GUI, command line, embedding and scripting interface (based on Python) to its plotting facilities. It also allows for manipulation and editing of datasets. Feature changes from 0.99.0: * Import of Text datasets * Labels can be plotted next to X-Y points * Numbers can be directly plotted by entering into X-Y datasets as X and Y * More line styles * Loaded document and functions are checked for unsafe Python features * Contours can be labelled with numbers * 2D dataset creation to make 2D datasets from x, y, z 1D datasets Bug and minor fixes from 0.99.0: * Zooming into X-Y images works now * Contour plots work on datasets with non equal X and Y sizes * Various fixes for datasets including NaN or Inf * Large changes to data import filter to support loading strings (and dates later) * Reduce number of undo levels for memory/speed * Text renderer rewritten to be more simple * Improved error dialogs * Proper error dialog for invalid loading of documents Features of package: * X-Y plots (with errorbars) * Line and function plots * Contour plots * Images (with colour mappings and colorbars) * Stepped plots (for histograms) * Fitting functions to data * Stacked plots and arrays of plots * Plot keys * Plot labels * LaTeX-like formatting for text * EPS/PDF/PNG export * Scripting interface * Dataset creation/manipulation * Embed Veusz within other programs * Text, CSV and FITS importing Requirements: Python (2.3 or greater required) http://www.python.org/ Qt >= 4.3 (free edition) http://www.trolltech.com/products/qt/ PyQt >= 4.3 (SIP is required to be installed first) http://www.riverbankcomputing.co.uk/pyqt/ http://www.riverbankcomputing.co.uk/sip/ numpy >= 1.0 http://numpy.scipy.org/ Microsoft Core Fonts (recommended for nice output) http://corefonts.sourceforge.net/ PyFITS >= 1.1 (optional for FITS import) http://www.stsci.edu/resources/software_hardware/pyfits For documentation on using Veusz, see the "Documents" directory. The manual is in pdf, html and text format (generated from docbook). Issues: * Reqires a rather new version of PyQt, otherwise dialogs don't work. * Can be very slow to plot large datasets if antialiasing is enabled. Right click on graph and disable antialias to speed up output. * The embedding interface appears to crash on exiting. If you enjoy using Veusz, I would love to hear from you. Please join the mailing lists at https://gna.org/mail/?group=veusz to discuss new features or if you'd like to contribute code. The latest code can always be found in the SVN repository.

Bazaar 0.92 release candidate 1
by Andrew Bennetts 28 Oct '07

28 Oct '07

I'm happy to announce the first release candidate of Bazaar 0.92. This release contains around 30 distinct user visible enhancements and bug-fixes. There are some substantial improvements to speed, particularly of commit operations. A new experimental repository format has been added. Details of the changes are given below. Bazaar is a fast, friendly and free distributed revision control system written in Python and available under the GPL v2 or later. See http://bazaar-vcs.org/ for more details. The Python source code is available from http://bazaar-vcs.org/releases/src/bzr-0.92rc1.tar.gz. Packages and Windows installers will be linked from http://bazaar-vcs.org/Download as they become available. This release will become Bazaar 0.92 in about a week, depending on user feedback. We'd particularly appreciate feedback on use of Bazaar on non-Linux i386 platforms. Thank you very much to the many people that have contributed to this release! -Andrew, on behalf of the Bazaar team bzr 0.92rc1 2007-10-29 ====================== CHANGES: * ``bzr`` now returns exit code 4 if an internal error occurred, and 3 if a normal error occurred. (Martin Pool) * ``pull``, ``merge`` and ``push`` will no longer silently correct some repository index errors that occured as a result of the Weave disk format. Instead the ``reconcile`` command needs to be run to correct those problems if they exist (and it has been able to fix most such problems since bzr 0.8). Some new problems have been identified during this release and you should run ``bzr check`` once on every repository to see if you need to reconcile. If you cannot ``pull`` or ``merge`` from a remote repository due to mismatched parent errors - a symptom of index errors - you should simply take a full copy of that remote repository to a clean directory outside any local repositories, then run reconcile on it, and finally pull from it locally. (And naturally email the repositories owner to ask them to upgrade and run reconcile). (Robert Collins) FEATURES: * New ``knitpack-experimental`` repository format. This is interoperable with the ``dirstate-tags`` format but uses a smarter storage design that greatly speeds up many operations, both local and remote. This new format can be used as an option to the ``init``, ``init-repository`` and ``upgrade`` commands. See http://doc.bazaar-vcs.org/latest/developers/knitpack.html for further details. (Robert Collins) * For users of bzr-svn (and those testing the prototype subtree support) that wish to try packs, a new ``knitpack-subtree-experimental`` format has also been added. This is interoperable with the ``dirstate-subtrees`` format. (Robert Collins) * New ``reconfigure`` command. (Aaron Bentley) * New ``revert --forget-merges`` command, which removes the record of a pending merge without affecting the working tree contents. (Martin Pool) * New ``bzr_remote_path`` configuration variable allows finer control of remote bzr locations than BZR_REMOTE_PATH environment variable. (Aaron Bentley) * New ``launchpad-login`` command to tell Bazaar your Launchpad user ID. This can then be used by other functions of the Launchpad plugin. (James Henstridge) PERFORMANCE: * Commit in quiet mode is now slightly faster as the information to output is no longer calculated. (Ian Clatworthy) * Commit no longer checks for new text keys during insertion when the revision id was deterministically unique. (Robert Collins) * Committing a change which is not a merge and does not change the number of files in the tree is faster by utilising the data about whether files are changed to determine if the tree is unchanged rather than recalculating it at the end of the commit process. (Robert Collins) * Inventory serialisation no longer double-sha's the content. (Robert Collins) * Knit text reconstruction now avoids making copies of the lines list for interim texts when building a single text. The new ``apply_delta`` method on ``KnitContent`` aids this by allowing modification of the revision id such objects represent. (Robert Collins) * Pack indices are now partially parsed for specific key lookup using a bisection approach. (Robert Collins) * Partial commits are now approximately 40% faster by walking over the unselected current tree more efficiently. (Robert Collins) * XML inventory serialisation takes 20% less time while being stricter about the contents. (Robert Collins) * Graph ``heads()`` queries have been fixed to no longer access all history unnecessarily. (Robert Collins) IMPROVEMENTS: * ``bzr+https://`` smart server across https now supported. (John Ferlito, Martin Pool, #128456) * Mutt is now a supported mail client; set ``mail_client=mutt`` in your bazaar.conf and ``send`` will use mutt. (Keir Mierle) * New option ``-c``/``--change`` for ``merge`` command for cherrypicking changes from one revision. (Alexander Belchenko, #141368) * Show encodings, locale and list of plugins in the traceback message. (Martin Pool, #63894) * Experimental directory formats can now be marked with ``experimental = True`` during registration. (Ian Clatworthy) DOCUMENTATION: * New *Bazaar in Five Minutes* guide. (Matthew Revell) * The hooks reference documentation is now converted to html as expected. (Ian Clatworthy) BUG FIXES: * Connection error reporting for the smart server has been fixed to display a user friendly message instead of a traceback. (Ian Clatworthy, #115601) * Make sure to use ``O_BINARY`` when opening files to check their sha1sum. (Alexander Belchenko, John Arbash Meinel, #153493) * Fix a problem with Win32 handling of the executable bit. (John Arbash Meinel, #149113) * ``bzr+ssh://`` and ``sftp://`` URLs that do not specify ports explicitly no longer assume that means port 22. This allows people using OpenSSH to override the default port in their ``~/.ssh/config`` if they wish. This fixes a bug introduced in bzr 0.91. (Andrew Bennetts, #146715) * Commands reporting exceptions can now be profiled and still have their data correctly dumped to a file. For example, a ``bzr commit`` with no changes still reports the operation as pointless but doing so no longer throws away the profiling data if this command is run with ``--lsprof-file callgrind.out.ci`` say. (Ian Clatworthy) * Fallback to ftp when paramiko is not installed and sftp can't be used for ``tests/commands`` so that the test suite is still usable without paramiko. (Vincent Ladeuil, #59150) * Fix commit ordering in corner case. (Aaron Bentley, #94975) * Fix long standing bug in partial commit when there are renames left in tree. (Robert Collins, #140419) * Fix selftest semi-random noise during http related tests. (Vincent Ladeuil, #140614) * Fix typo in ftp.py making the reconnection fail on temporary errors. (Vincent Ladeuil, #154259) * Fix failing test by comparing real paths to cover the case where the TMPDIR contains a symbolic link. (Vincent Ladeuil, #141382). * Fix log against smart server branches that don't support tags. (James Westby, #140615) * Fix pycurl http implementation by defining error codes from pycurl instead of relying on an old curl definition. (Vincent Ladeuil, #147530) * Fix 'unprintable error' message when displaying BzrCheckError and some other exceptions on Python 2.5. (Martin Pool, #144633) * Fix ``Inventory.copy()`` and add test for it. (Jelmer Vernooij) * Handles default value for ListOption in cmd_commit. (Vincent Ladeuil, #140432) * HttpServer and FtpServer need to be closed properly or a listening socket will remain opened. (Vincent Ladeuil, #140055) * Monitor the .bzr directory created in the top level test directory to detect leaking tests. (Vincent Ladeuil, #147986) * The basename, not the full path, is now used when checking whether the profiling dump file begins with ``callgrind.out`` or not. This fixes a bug reported by Aaron Bentley on IRC. (Ian Clatworthy) * Trivial fix for invoking command ``reconfigure`` without arguments. (Rob Weir, #141629) * ``WorkingTree.rename_one`` will now raise an error if normalisation of the new path causes bzr to be unable to access the file. (Robert Collins) * Correctly detect a NoSuchFile when using a filezilla server. (Gary van der Merwe) API BREAKS: * ``bzrlib.index.GraphIndex`` now requires a size parameter to the constructor, for enabling bisection searches. (Robert Collins) * ``CommitBuilder.record_entry_contents`` now requires the root entry of a tree be supplied to it, previously failing to do so would trigger a deprecation warning. (Robert Collins) * ``KnitVersionedFile.add*`` will no longer cache added records even when enable_cache() has been called - the caching feature is now exclusively for reading existing data. (Robert Collins) * ``ReadOnlyLockError`` is deprecated; ``LockFailed`` is usually more appropriate. (Martin Pool) * Removed ``bzrlib.transport.TransportLogger`` - please see the new ``trace+`` transport instead. (Robert Collins) * Removed previously deprecated varargs interface to ``TestCase.run_bzr`` and deprecated methods ``TestCase.capture`` and ``TestCase.run_bzr_captured``. (Martin Pool) * Removed previous deprecated ``basis_knit`` parameter to the ``KnitVersionedFile`` constructor. (Robert Collins) * Special purpose method ``TestCase.run_bzr_decode`` is moved to the test_non_ascii class that needs it. (Martin Pool) * The class ``bzrlib.repofmt.knitrepo.KnitRepository3`` has been folded into ``KnitRepository`` by parameters to the constructor. (Robert Collins) * The ``VersionedFile`` interface now allows content checks to be bypassed by supplying check_content=False. This saves nearly 30% of the minimum cost to store a version of a file. (Robert Collins) * Tree's with bad state such as files with no length or sha will no longer be silently accepted by the repository XML serialiser. To serialise inventories without such data, pass working=True to write_inventory. (Robert Collins) * ``VersionedFile.fix_parents`` has been removed as a harmful API. ``VersionedFile.join`` will no longer accept different parents on either side of a join - it will either ignore them, or error, depending on the implementation. See notes when upgrading for more information. (Robert Collins) INTERNALS: * ``bzrlib.transport.Transport.put_file`` now returns the number of bytes put by the method call, to allow avoiding stat-after-write or housekeeping in callers. (Robert Collins) * ``bzrlib.xml_serializer.Serializer`` is now responsible for checking that mandatory attributes are present on serialisation and deserialisation. This fixes some holes in API usage and allows better separation between physical storage and object serialisation. (Robert Collins) * New class ``bzrlib.errors.InternalBzrError`` which is just a convenient shorthand for deriving from BzrError and setting internal_error = True. (Robert Collins) * New method ``bzrlib.mutabletree.update_to_one_parent_via_delta`` for moving the state of a parent tree to a new version via a delta rather than a complete replacement tree. (Robert Collins) * New method ``bzrlib.osutils.minimum_path_selection`` useful for removing duplication from user input, when a user mentions both a path and an item contained within that path. (Robert Collins) * New method ``bzrlib.repository.Repository.is_write_locked`` useful for determining if a repository is write locked. (Robert Collins) * New method on ``bzrlib.tree.Tree`` ``path_content_summary`` provides a tuple containing the key information about a path for commit processing to complete. (Robert Collins) * New method on xml serialisers, write_inventory_to_lines, which matches the API used by knits for adding content. (Robert Collins) * New module ``bzrlib.bisect_multi`` with generic multiple-bisection-at-once logic, currently only available for byte-based lookup (``bisect_multi_bytes``). (Robert Collins) * New helper ``bzrlib.tuned_gzip.bytes_to_gzip`` which takes a byte string and returns a gzipped version of the same. This is used to avoid a bunch of api friction during adding of knit hunks. (Robert Collins) * New parameter on ``bzrlib.transport.Transport.readv`` ``adjust_for_latency`` which changes readv from returning strictly the requested data to inserted return larger ranges and in forward read order to reduce the effect of network latency. (Robert Collins) * New parameter yield_parents on ``Inventory.iter_entries_by_dir`` which causes the parents of a selected id to be returned recursively, so all the paths from the root down to each element of selected_file_ids are returned. (Robert Collins) * Knit joining has been enhanced to support plain to annotated conversion and annotated to plain conversion. (Ian Clatworthy) * The CommitBuilder method ``record_entry_contents`` now returns summary information about the effect of the commit on the repository. This tuple contains an inventory delta item if the entry changed from the basis, and a boolean indicating whether a new file graph node was recorded. (Robert Collins) * The python path used in the Makefile can now be overridden. (Andrew Bennetts, Ian Clatworthy) TESTING: * New transport implementation ``trace+`` which is useful for testing, logging activity taken to its _activity attribute. (Robert Collins) * When running bzr commands within the test suite, internal exceptions are not caught and reported in the usual way, but rather allowed to propagate up and be visible to the test suite. A new API ``run_bzr_catch_user_errors`` makes this behavior available to other users. (Martin Pool) * New method ``TestCase.call_catch_warnings`` for testing methods that raises a Python warning. (Martin Pool)

ANNOUNCE: wxPython 2.8.6.1
by Robin Dunn 28 Oct '07

28 Oct '07

Announcing ---------- The 2.8.6.1 release of wxPython is now available for download at http://wxpython.org/download.php. This release has a number of important bug fixes and is a general improvement of the 2.8.6.0 release. Source code is available, as well as binaries for Python 2.3, 2.4 and 2.5, for Windows and Mac, as well some pacakges for various Linux distributions. A summary of changes is listed below and also at http://wxpython.org/recentchanges.php. What is wxPython? ----------------- wxPython is a GUI toolkit for the Python programming language. It allows Python programmers to create programs with a robust, highly functional graphical user interface, simply and easily. It is implemented as a Python extension module that wraps the GUI components of the popular wxWidgets cross platform library, which is written in C++. wxPython is a cross-platform toolkit. This means that the same program will usually run on multiple platforms without modifications. Currently supported platforms are 32-bit Microsoft Windows, most Linux or other Unix-like systems using GTK2, and Mac OS X 10.3+, in most cases the native widgets are used on each platform to provide a 100% native look and feel for the application. Changes in 2.8.6.1 ------------------ wxMac: Fixed paste bug when the clipboard contains unicode text. AUI: Added missing event binders for the notebok tab events. wxMac: Fixed bug that resulted in portions of virtual listctrl's to not be repainted when scrolling with PgUp/PgDown/Home/End. wxMac: Fixed bug that broke tab traversal when tabbing runs into a wx.StaticBox. wxGTK: Add wx.Window.GetGtkWidget. All: Undprecated wx.ListCtrl.[G|S]etItemSpacing All: Fixed wx.Palette constructor wrapper. It takes three seqences of integers to specify the R, G, and B values for each color in the palette, which must all be the same length and which must contain integer values in the range of 0..255 inclusive. Thanks to some grunt work from Edouard TISSERANT, wxPython now has the needed tweaks in config.py to be able to be built with mingw32. See BUILD.txt for details. Changes in wx.GraphicsContext to make things like the half-pixel offsets more consistent across platforms. wxMSW: If freezing a top-level window wxWidgets will actually freeze the TLW's children instead. This works around a feature of MS Windows that allowed windows beneath the frozen one in Z-order to paint through, and also mouse events clicking through to the lower window. -- Robin Dunn Software Craftsman http://wxPython.org Java give you jitters? Relax with wxPython!

fclient project seeking co-coders
by Jürgen Urner 28 Oct '07

28 Oct '07

Hello all, I Just recently registered a project fclient to sourceforge.net [http://sourceforge.net/projects/fclient]. fclient is intended to become desktop client for the freenet [freenetproject.org] network written in python and Qt4. fclient is very alpha, in fact only parts of the freenet client protocol are curently implementated and loads of work ahead. But I would appreciate very much finding interested co-coders to take part in the project. Me, I am no professional coder, but an enthusiast with one or the other year of python (and Qt) experience. If interested in the project (and freenet), feel free to drop a mail to the users mailing list at the project page. Have fun, Juergen

ANN: cssutils 0.9.4a2
by Christof Hoeke 27 Oct '07

27 Oct '07

what is it ---------- A Python package to parse and build CSS Cascading Style Sheets. changes since 0.9.4a1 --------------------- for full details see the relevant README file http://cssutils.googlecode.com/svn/tags/TAG_0.9.4a2/README.txt - **FEATURE**: added ``Preferences.useMinified()`` which sets preferences that a stylesheet will be serialized as compact as possible. Added ``Preferences.useDefaults()`` which resets the serializer preferences. There a few new preferences have been added as well (see the documentation for details as most are hardly useful for normal usage of the library) + **BUGFIX**: Fixed parsing of ``font`` value which uses "font-size/line-height" syntax. - CHANGE: ``Preferences.keepAllProperties`` defaults to ``True`` now (hardly used but safer if different values have been set which are used by different UAs for example.) license ------- cssutils is published under the LGPL. download -------- for download options for cssutils 0.9.4a2 - 071027 see http://cthedot.de/cssutils/ cssutils needs * Python 2.4 or higher (tested with Python 2.5 on Vista only) bug reports, comments, etc are very much appreciated! thanks Christof

ANN: Leo 4.4.4 beta 4 released
by Edward K Ream 27 Oct '07

27 Oct '07

Leo 4.4.4 beta 4 is available at: http://sourceforge.net/project/showfiles.php?group_id=3458&package_id=29106 This beta 4 version fixes all bugs reported against Leo 4.4.4 beta 3. Leo is a text editor, data organizer, project manager and much more. See: http://webpages.charter.net/edreamleo/intro.html Leo 4.4.4 contains many important features originally planned for later releases. The highlights of Leo 4.4.4: ---------------------------- - The Great Graph Aha (tm): simple scripts allow Leo outlines to represent arbitrary directed graphs. There is no need for a separate 'graph world'. The graphed.py plugin is a direct result of this Aha. The graphed.py plugin allows you to create general graphs from Leo outlines. - @menus trees in settings files create all of Leo's menus. It is now dead easy to make Leo's menus look the way you want. - @buttons trees in settings files create common @button nodes created in all Leo outlines. - @auto nodes eliminate sentinels in derived files, thereby allowing people to collaborate using Leo more easily. - New commands for resolving cvs conflicts. - A threading_colorizer plugin replaces the __jEdit_colorizer__ plugin. This plugin features much better performance and a new, elegant algorithm. - Leo is now compatible with jython. - Better support for icons in headlines. - The usual assortment of bug fixes and other minor improvements.

The second beta version of Browsershots 0.4 has been released under the GNU GPL (Version 3) today. Browsershots is a distributed system for automatically making screenshots of web content in different browsers. Both the server and the screenshot factory software are written in Python. Project Status: Version 0.4 is a full rewrite of Browsershots, based on the Django framework. It is still not feature complete, but already quite usable. The public demo at browsershots.org is running the latest trunk code with more than 5,000 visits (50,000 pageviews) per day. Version 0.3 has been retired after the release of 0.3.0 which was announced here: http://trac.browsershots.org/wiki/BlogRelease030 Highlights of this release: The source code was updated to work with the latest Django. Several language translations were added. The biggest new features are self-registration for new users and standalone mode for the screenshot factory. Summary of changes since 0.4-alpha1: * Improved documentation. * Updated to latest Django. * Added several languages and improved existing translations. * Less output for ShotFactory if not running --verbose. * [2027] Display ads on the site, if configured in settings.py. * [2030] Fixed queue estimates (added missing platform clause). * [2075] Use RequestContext everywhere. * [2088] Self-registration for new users, with email verification. * [2120] Show heavy users at /status/usage/ (login required). * [2130] Show volunteers with 4800 or more uploads per day on the front page. * [2156] Don't save page content in the website table. * [2158] Show server status overview at /status/ (login required). * [2165] Added browser and OS icons (collected by Marcin Król). * [2178] Script to delete old screenshots until we have sufficient free disk space. * [2179] Added long options for the command line, see shotfactory.py --help for a complete list. * [2197] Let factory admins add and remove screen sizes and color depths. * Added ShotFactoryStandalone features for operation without a ShotServer. * [2203] More helpful error page for unknown URLs. * [2214] Improved delete_if_exists() to allow shell wildcards. * [2243] Added reset_browser() for all browsers. * [2245] Added scroll_bottom() for all browsers. Release announcements: http://freshmeat.net/projects/browsershots/ http://trac.browsershots.org/wiki/BlogRelease04beta2 http://trac.browsershots.org/milestone/0.4-beta2 Source code: http://sourceforge.net/project/showfiles.php?group_id=202792 http://trac.browsershots.org/browser/tags/0.4-beta2/ http://svn.browsershots.org/tags/0.4-beta2/ Timeline (history) and roadmap (future): http://trac.browsershots.org/timeline http://trac.browsershots.org/roadmap Synopsis: Browsershots is a distributed system for automatically making screenshots of web content in different browsers.
