"re-try" 0.7: Try Python regular expressions online
by Christof Hoeke 28 Mar '09

28 Mar '09

====== re-try ====== :version: 0.7 URL --- http://re-try.appspot.com/ what is it ---------- A small online browser application to try out Python regular expressions. It is based on http://cthedot.de/retest/ which has been around for some years but I never had a Python hosting service available so was only availabel for download. Putting it online on GAE was very easy though. The source code is not available publicly, if you are interested I might put it on Google Code or so. It is strongly based on retest 0.6.1 so no real surprises anyway. Please let me know what you think! thanks Christof

[ANN] pyxser-0.1r (release 0.1)
by Daniel Molina Wegener 27 Mar '09

27 Mar '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 - From the readme file: - -----8<----------8<----------8<----------8<----- pxyser --- python xml serialization pyxser stands for Python XML Serialization, it's Python object serializer that does the job in a standard way. Unlike other serializers, it uses structured document defined in the pyxser DTD, has a FPI (forma public identifier) and the deserialization process run before validating the serialized object document against the pyxser DTD. it has the next functions: string pyxser.serialize(object) serilizes the given object and return it's XML representation. object pyxser.unserialize(string) deserializes the given string into it's native python reprsentation. it needs that all modules referenced in the serilized XML can be accesible to the pyxser extension. boolean pyxser.validate(string) validates the given XML string against the pyxser DTD. you don't need to call this function before every deserialization, because pyxser does the validation internally. A sample of a serialized object is the XML as follows: <?xml version="1.0" encoding="utf-8"?> <pyxs:obj xmlns:pyxs="http://projects.coder.cl/pyxser/model/" version="1.0" type="TestAnotherObject" module="testpkg.sample" id="id-136688140"> <pyxs:prop type="str" name="first_element">456</pyxs:prop> <pyxs:prop type="str" name="second_element">789</pyxs:prop> </pyxs:obj> pyxser supports cross referenced objects and nested referenced object, because it defines the a ref attribute as IDREF which is used to link internal nodes in the document tree. *** See the INSTALLING file for installing instructions. *** *** See the AUTHORS file to get information about the authors *** The pyxser web page is: http://coder.cl/software/pyxser/ Best regards, Daniel Molina Wegener ### $Id: README 29 2009-03-27 01:59:57Z damowe $ ### - -----8<----------8<----------8<----------8<----- Best regards, - -- .O. | Daniel Molina Wegener | FreeBSD & Linux ..O | dmw [at] coder [dot] cl | Open Standards OOO | http://coder.cl/ | FOSS Developer -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (FreeBSD) iQIcBAEBCgAGBQJJzEbaAAoJEHxqfq6Y4O5NXcEQAJQQqEWKvfbEKHZWC3RP4B/w isuiiyuVig7+nsBvRFoqoeTj5JtAUBN4xykH3TiqojYM7osA9+dPDRg7JfJtjf1t EaCB7u3HuIeR5udyoMpFSEpmJejr7gcMwOWLhBHZrhpgxhiAsioC1QjBtHsSnsuz 8pPp9/eqdTLvPhgkk8shFq0tvkM0pvF4/E9c4AACqz96frZO+S0jiIqPnu2VOkSq UX+/H2HkvvoDkh6+nS3vafC2VKC4U0c3MSu2rgljuxp5sDOBJLEYixCzw/U7Dtdo jgD12LPnqPa/3sQY2FsNkYosIp+Aj5C09i/jCc+MMw9RDJ3QmJaZtfC+0stU32xV w/WiOFjmGrgc+H3UmQXALdbTSbK/WyjX/iJ4R+04GCZW2y6b1IJwis//mPiWZe+K KgREo3KBx2wE/rrrHHEfmQZX/zaSxbY+qL4696OrB7q2lduyG6izmVBaOColJ/eY 5QDVrP0Y+NUL0j6rgd9gJj4/cG2sVr9aQant2WizwKSMK/fh3k/8gOLXU6JMjYTI e7mWWfjRrJGvgDGUD42EmAnuVXa4OAZUC20uH/kpCvfr+iAfM0WXk/6kzw1Qcu7o dHqXGK4/vHcVlX0UnJE843d5+eok932SkZPRLvM6L8pdwjB8nJ17P85pkfgysUDh Ofk5cKuQ2HF+EgH5Quki =QhlG -----END PGP SIGNATURE-----

Sphinx 0.6.1 and 0.5.2 released
by Georg Brandl 26 Mar '09

26 Mar '09

Hi all, I'm proud to announce the release of Sphinx 0.6.1 and 0.5.2. Sphinx 0.5.2 is a bugfix-only release in the 0.5 series, while 0.6.1 is a feature release, containing all of 0.5.2's fixes together with many added features. These are beta releases, so please test them out and report any bugs to sphinx-dev(a)googlegroups.com or the tracker at <http://bitbucket.org/birkenfeld/sphinx/>. Thank you! The finals will be out in a week's time, if no severe problems are uncovered. What is it? =========== Sphinx is a tool that makes it easy to create intelligent and beautiful documentation for Python projects (or other documents consisting of multiple reStructuredText source files). Website: http://sphinx.pocoo.org/ What's new in 0.6 (short version)? ================================== Long version: http://sphinx.pocoo.org/latest/changes.html * General/Markup: - Templating now requires the Jinja2 library, which is an enhanced version of the old Jinja1 engine. - Theming support, see the new section in the documentation. - Due to popular demand, added a ``:doc:`` role which directly links to another document without the need of creating a label to which a ``:ref:`` could link to. - Added a ``:download:`` role that marks a non-document file for inclusion into the HTML output and links to it. - Added an ``only`` directive that can selectively include text based on enabled "tags". Tags can be given on the command line. Also, the current builder output format (e.g. "html" or "latex") is always a defined tag. - Added HTML section numbers, enabled by giving a ``:numbered:`` flag to the ``toctree`` directive. - The ``literalinclude`` directive now supports several more options, to include only parts of a file. - The ``toctree`` directive now supports a ``:hidden:`` flag, which will prevent links from being generated in place of the directive -- this allows you to define your document structure, but place the links yourself. - Paths to images, literal include files and download files can now be absolute (like ``/images/foo.png``). They are treated as relative to the top source directory. - SVG images are now supported in HTML (via ``<object>`` and ``<embed>`` tags). * Configuration: - The new config value ``rst_epilog`` can contain reST that is appended to each source file that is read. This is the right place for global substitutions. - The new ``html_add_permalinks`` config value can be used to switch off the generated "paragraph sign" permalinks for each heading and definition environment. - The new ``html_show_sourcelink`` config value can be used to switch off the links to the reST sources in the sidebar. - The default value for ``htmlhelp_basename`` is now the project title, cleaned up as a filename. - The new ``modindex_common_prefix`` config value can be used to ignore certain package names for module index sorting. - The new ``trim_footnote_reference_space`` config value mirrors the docutils config value of the same name and removes the space before a footnote reference that is necessary for reST to recognize the reference. - The new ``latex_additional_files`` config value can be used to copy files (that Sphinx doesn't copy automatically, e.g. if they are referenced in custom LaTeX added in ``latex_elements``) to the build directory. * Builders: - The new ``DirectoryHTMLBuilder`` (short name ``dirhtml``) creates a separate directory for every page, and places the page there in a file called ``index.html``. Therefore, page URLs and links don't need to contain ``.html``. - The new ``html_link_suffix`` config value can be used to select the suffix of generated links between HTML files. - #96: The LaTeX builder now supports figures wrapped by text, when using the ``figwidth`` option and right/left alignment. * New translations: - Italian by Sandro Dentella. - Ukrainian by Petro Sasnyk. - Finnish by Jukka Inkeri. * Extensions and API: - New ``graphviz`` extension to embed graphviz graphs. - New ``inheritance_diagram`` extension to embed... inheritance diagrams! - New ``autosummary`` extension that generates summaries of modules and automatic documentation of modules. - Autodoc now has a reusable Python API, which can be used to create custom types of objects to auto-document (e.g. Zope interfaces). See also ``Sphinx.add_autodocumenter()``. - Autodoc now handles documented attributes. - Autodoc now handles inner classes and their methods. - Autodoc can document classes as functions now if explicitly marked with `autofunction`. - Autodoc can now exclude single members from documentation via the ``exclude-members`` option. - Autodoc can now order members either alphabetically (like previously) or by member type; configurable either with the config value ``autodoc_member_order`` or a ``member-order`` option per directive. * New command-line features: - Config overrides for single dict keys can now be given on the command line. - Source links in HTML are now generated with ``rel="nofollow"``. - Quickstart can now generate a Windows ``make.bat`` file. - There is now a ``-w`` option for sphinx-build that writes warnings to a file, in addition to stderr. - There is now a ``-W`` option for sphinx-build that turns warnings into errors. cheers, Georg

Announcing IronPython 2.6 Alpha 1
by Dave Fugate 26 Mar '09

26 Mar '09

Hello Python Community, We're pleased to announce the release of IronPython 2.6 Alpha 1. As you might imagine, this release is all about supporting new CPython 2.6 features such as the 'bytes' and 'bytearray' types (PEP 3112), decorators for classes (PEP 3129), advanced string formatting (PEP 3101), etc. The minimum .NET version required for this release is the same as IronPython 2.0; namely .NET 2.0 Service Pack 1. Unlike the 2.0 series of IronPython, we plan to release only a couple Alphas and Betas of IronPython 2.6. As such, it's key that we get your feedback on the release(s) quickly to incorporate requested changes. Besides CPython 2.6 features, another significant change in this release is that ipy.exe now uses "adaptive compilation" by default. Adaptive compilation is a technique in which IronPython: 1. Interprets and executes Python method calls up to N times for a given method. If you're only going to execute a method a few times, it's typically faster to interpret the method instead of compiling and executing it 2. Compiles and executes the Python method call on the N+1 invocation of the method. Compilation of a Python method is a heavyweight operation, but we can reuse the result for subsequent invocations 3. Reuses the previously compiled method for new calls to the Python method. This operation is much faster than interpreting the method call as the method was already compiled in the previous step The reason for this change is that it provides a nice performance gain for Python code containing lots of functions/methods that only get called a few times. All this said, this feature is still undergoing active development and as a consequence some Python scripts may actually run slower with it turned on. For this reason, our old default mode of running Python scripts is still available by passing the -O or -D flags to ipy.exe. Any feedback on how this new feature affects your IronPython applications performance-wise would be greatly appreciated. There's also a few minor changes since IronPython 2.0.1 that are worth calling out here: * IronPython.msi now installs NGEN'ed binaries by default * IronPython.msi now offers a little more selection with respect to what you'd like to install. For example, Silverlight templates are optional * The default installation location of IronPython.msi no longer indicates whether the 2.6 release is an Alpha, Beta, or a patched release. Future IronPython 2.6 installations will replace previous 2.6 releases which will be uninstalled automatically * The -X:PreferComInteropAssembly flag has been removed. All COM interop is now done through normal COM dispatch You can download IronPython 2.6 Alpha 1 at: http://ironpython.codeplex.com/Release/ProjectReleases.aspx?ReleaseId=22982 The IronPython Team

"Advanced Scientific Programming in Python" Summer School in Berlin, Germany
by Tiziano Zito 25 Mar '09

25 Mar '09

"Advanced Scientific Programming in Python" a G-Node Summer School Many scientists spend much of their time writing, debugging, and maintaining software. But while techniques for doing this efficiently have been developed, only few scientists actually use them. As a result, they spend far too much time writing deficient code and reinventing the wheel instead of doing research. In this course we present a selection of advanced programming techniques with theoretical lectures and practical exercises tailored to the needs of the programming scientist. To spice up theory and foster our new skills in a real-world programming project, we will team up to develop an entertaining scientific computer game. We will use the Python programming language for the entire course. With a large collection of open-source scientific modules and all features of a full-fledged programming language, Python is rapidly gaining popularity in the neuroscience community. It enables the scientist to quickly develop powerful, efficient, and structured software and is becoming an essential tool for scientific computing. The summer school is targeted at Post-docs and PhD students from all areas of neuroscience. Substantial proficiency in Python or in another language (e.g. Java, C/C++, MATLAB, Mathematica) is absolutely required. An optional, one-day pre-course is offered to participants without Python experience to familiarize with the language. Date and Location ----------------- August 31st, 2009 -- September 4th, 2009. Berlin, Germany. Preliminary Program ------------------- Day 0 (Mon Aug 31) -- [Optional] Dive into Python Day 1 (Tue Sep 1) -- Software Carpentry - Documenting code and using version control - Test-driven development & unit testing - Debugging, profiling and benchmarking techniques - Object-oriented programming, design patterns and Extreme Programming Day 2 (Wed Sep 2) -- Scientific Tools for Python - NumPy, SciPy, Matplotlib, IPython - Neuroscience libraries - Programming project in the afternoon Day 3 (Thu Sep 3) -- Parallelization - Python multiprocessing for SMP machines - Distributed parallelization for cluster computing - Programming project in the afternoon Day 4 (Fri Sep 4) -- Practical Software Development - Software design - Efficient programming in teams - Quality Assurance - Finalizing the programming project Applications ------------ Applications should be sent before May 31st, 2009 to pythonsummerschool(a)bccnberlin.de. No fee is charged but participants should take care of travel, living, and accommodation expenses. Applications should include full contact information (name, affiliation, email & phone), a short CV and a short statement addressing the following questions (maximum 500 words): - What is your educational background? - What experience do you have in programming? - Why do you think "Advanced Scientific Programming in Python" is an appropriate course for your skill profile? Candidates will be selected based on their profile. Places are limited: early application is recommended.

bzr 1.13.1 released!
by Bob Tanner 23 Mar '09

23 Mar '09

A couple regessions where found in the 1.13 release. The pyrex- generated C extensions are missing from the .tar.gz and .zip files. Documentation on how to generate GNU ChangeLogs is wrong. The merge --force works again. The Bazaar team announces the availability of a regression release of the bzr adaptive version control system. Thanks to everyone who contributed patches, suggestions, and feedback. Bazaar is now available for download from http://bazaar-vcs.org/ Download as a source tarball; packages for various systems will be available soon. BUG FIXES: * Change ``./bzr``'s ``_script_version`` to match ./bzrlib/ __init__.py version_info. (Bob Tanner, Martin Pool, #345232) * Distribution archives for 1.13 do not contain generated C extension modules (Jean-Francois Roy, Bob Tanner, #344465) * GNU ChangeLog output can now be produced by bzr log --format gnu-changelog is incorrect (Deejay, Bob Tanner, Martin Pool, Robert Collins, #343928) * ``merge --force`` works again.

ETS 3.2.0 Released
by Dave Peterson 23 Mar '09

23 Mar '09

Hello, I'm pleased to announce that Enthought Tool Suite (ETS) version 3.2.0 has been tagged and released! Source distributions (.tar.gz) have been uploaded to PyPi, and Windows binaries will be follow shortly. A full install of ETS can be done using Setuptools via a command like: easy_install -U "ets[nonets] >= 3.2.0" NOTE 1: Users of an old ETS release will need to first uninstall prior to installing the new ETS. NOTE 2: If you get a 'SandboxViolation' error, simply re-run the command again -- it may take multiple invocations to get everything installed. (This error appears to be a long-standing incompatibility between numpy.distutils and setuptools.) Please see below for a list of what's new in this release. What Is ETS? =========== The Enthought Tool Suite (ETS) is a collection of components developed by Enthought and the open-source community, which we use every day to construct custom scientific applications. It includes a wide variety of components, including: * an extensible application framework * application building blocks * 2-D and 3-D graphics libraries * scientific and math libraries * developer tools The cornerstone on which these tools rest is the Traits package, which provides explicit type declarations in Python; its features include initialization, validation, delegation, notification, and visualization of typed attributes. More information on ETS is available from the development home page: http://code.enthought.com/projects/index.php Changelog ========= ETS 3.2.0 is a feature-added update to ETS 3.1.0, including numerous bug-fixes. Some of the notable changes include: Chaco ----- * Domain limits - Mappers now can declare the "limits" of their valid domain. PanTool and ZoomTool respect these limits. (pwang) * Adding "hide_grids" parameter to Plot.img_plot() and Plot.contour_plot() so users can override the default behavior of hiding grids. (pwang) * Refactored examples to declare a Demo object so they can be be run with the demo.py example launcher. (vibha) * Adding chaco.overlays package with some canned SVG overlays. (bhendrix) * DragZoom now can scale both X and Y axes independently corresponding to the mouse cursor motion along the X and Y axes (similar to the zoom behavior in Matplotlib). (pwang) * New Examples: * world map (bhendrix) * more financial plots (pwang) * scatter_toggle (pwang) * stacked_axis (pwang) * Fixing the chaco.scales TimeFormatter to use the built-in localtime() instead of the one in the safetime.py module due to Daylight Savings Time issues with timedelta. (r23231, pwang) * Improved behavior of ScatterPlot when it doesn't get the type of metadata it expects in its "selections" and "selection_masks" metadata keys (r23121, pwang) * Setting the .range2d attribute on GridMapper now properly sets the two DataRange1D instances of its sub-mappers. (r23119, pwang) * ScatterPlot.map_index() now respects the index_only flag (r23060, pwang) * Fixed occasional traceback/bug in LinePlot that occurred when data was completely outside the visible range (r23059, pwang) * Implementing is_in() on legends to account for padding and alignment (caused by tools that move the legend) (r23052, bhendrix) * Legend behaves properly when there are no plots to display (r23012, judah) * Fixed LogScale in the chaco.scales package to correctly handle the case when the length of the interval is less than a decade (r22907, warren.weckesser) * Fixed traceback when calling copy_traits() on a DataView (r22894, vibha) * Scatter plots generated by Plot.plot() now properly use the "auto" coloring feature of Plot. (r22727, pwang) * Reduced the size of screenshots in the user manual. (r22720, rkern) Mayavi ------ * 17, 18 March, 2009 (PR): * NEW: A simple example to show how one can use TVTK’s visual module with mlab. [23250] * BUG: The size trait was being overridden and was different from the parent causing a bug with resizing the viewer. [23243] * 15 March, 2009 (GV): * ENH: Add a volume factory to mlab that knows how to set color, vmin and vmax for the volume module [23221]. * 14 March, 2009 (PR): * API/TEST: Added a new testing entry point: ‘mayavi -t’ now runs tests in separate process, for isolation. Added enthought.mayavi.api.test to allow for simple testing from the interpreter [23195]...[23200], [23213], [23214], [23223]. * BUG: The volume module was directly importing the wx_gradient_editor leading to an import error when no wxPython is available. This has been tested and fixed. Thanks to Christoph Bohme for reporting this issue. [23191] * 14 March, 2009 (GV): * BUG: [mlab]: fix positioning for titles [23194], and opacity for titles and text [23193]. * ENH: Add the mlab_source attribute on all objects created by mlab, when possible [23201], [23209]. * ENH: Add a message to help the first-time user, using the new banner feature of the IPython shell view [23208]. * 13 March, 2009 (PR): * NEW/API: Adding a powerful TCP/UDP server for scripting mayavi via the network. This is available in enthought.mayavi.tools.server and is fully documented. It uses twisted and currently only works with wxPython. It is completely insecure though since it allows a remote user to do practically anything from mayavi. * 13 March, 2009 (GV) * API: rename mlab.orientationaxes to mlab.orientation_axes [23184] * 11 March, 2009 (GV) * API: Expose ‘traverse’ in mlab.pipeline [23181] * 10 March, 2009 (PR) * BUG: Fixed a subtle bug that affected the ImagePlaneWidget. This happened because the scalar_type of the output data from the VTKDataSource was not being set correctly. Getting the range of any input scalars also seems to silence warnings from VTK. This should hopefully fix issues with the use of the IPW with multiple scalars. I’ve added two tests for this, one is an integration test since those errors really show up only when the display is used. The other is a traditional unittest. [23166] * 08 March, 2009 (GV) * ENH: Raises an error when the user passes to mlab an array with infinite values [23150] * 07 March, 2009 (PR) * BUG: A subtle bug with a really gross error in the GridPlane component, I was using the extents when I should really have been looking at the dimensions. The extract grid filter was also not flushing the data changes downstream leading to errors that are also fixed now. These errors would manifest when you use an ExtractGrid to select a VOI or a sample rate and then used a grid plane down stream causing very wierd and incorrect rendering of the grid plane (thanks to conflation of extents and dimensions). This bug was seen at NAL for a while and also reported by Fred with a nice CME. The CME was then converted to a nice unittest by Suyog and then improved. Thanks to them all. [23146] * 28 February, 2009 (PR) * BUG: Fixed some issues reported by Ondrej Certik regarding the use Of mlab.options.offscreen, mlab.options.backend = ‘test’, removed cruft from earlier ‘null’ backend, fixed bug with incorrect imports, add_dataset set no longer adds one new null engine each time figure=False is passed, added test case for the options.backend test. [23088] * 23 February, 2009 (PR) * ENH: Updating show so that it supports a stop keyword argument that pops up a little UI that lets the user stop the mainloop temporarily and continue using Python [23049] * 21 February, 2009 (GV) * ENH: Add a richer view for the pipeline to the MayaviScene [23035] * ENH: Add safegards to capture wrong triangle array sizes in mlab.triangular_mesh_source. [23037] * 21 February, 2009 (PR) * ENH: Making the transform data filter recordable. [23033] * NEW: A simple animator class to make it relatively to create animations. [23036] [23039] * 20 February, 2009 (PR) * ENH: Added readers for various image file formats, poly data readers and unstructured grid readers. These include DICOM, GESigna, DEM, MetaImage (mha,mhd) MINC, AVSucd, GAMBIT, Exodus, STL, Points, Particle, PLY, PDB, SLC, OBJ, Facet and BYU files. Also added several tests for most of this functionality along with small data files. These are additions from PR’s project staff, Suyog Jain and Sreekanth Ravindran. [23013] * ENH: We now change the default so the ImagePlaneWidget does not control the LUT. Also made the IPW recordable. [23011] * 18 February, 2009 (GV) * ENH: Add a preference manager view for editing preferences outside envisage [22998] * 08 February, 2009 (GV) * ENH: Center the glyphs created by barchart on the data points, as mentioned by Rauli Ruohonen [22906] * 29 January, 2009 (GV) * ENH: Make it possible to avoid redraws with mlab by using mlab.gcf().scene.disable_render = True [22869] * 28 January, 2009 (PR and GV) * ENH: Make the mlab.pipeline.user_defined factory function usable to add arbitrary filters on the pipeline. [22867], [22865] * 11 January, 2009 (GV) * ENH: Make mlab.imshow use the ImageActor. Enhance the ImageActor to map scalars to colors when needed. [22816] Traits ------ * Fixed a bug whereby faulty error handling in the PyProtocols Pyrex speedup code keeps references to tracebacks that have been handled. In so doing, clean up the same code such that it can be used with a modern Pyrex release (a bare raise can no longer be used outside of an except: clause). * RangeEditor factory now supports a 'logslider' mode: Thanks to Matthew Turk for the patch * TabularEditor factory now supports editing of all columns: Thanks to Didrik Pinte for the patch * DateEditor factory in 'custom' style now supports multi-select feature. * DateEditor and TimeEditor now support the 'readonly' style. * Fixed a bug in the ArrayEditor factory that was causing multiple trait change events to get fired when the underlying array is changed externally to the editor: Thanks to Matthew Turk for he patch. * Fixed a circular import error in Color, Font and RGBColor traits * Fixed a bug in the factory for ArrayViewEditor so it now calls the toolkit backend-specific editor TraitsBackendWX --------------- * RangeEditor now supports a 'logslider' mode: Thanks to Matthew Turk for the patch * TabularEditor now supports editing of all columns: Thanks to Didrik Pinte for the patch * DateEditor in 'custom' style now supports multi-select feature. * DateEditor and TimeEditor now support the 'readonly' style. * Added a trait to the wx pyface workbench View to indicate if the view dock window should be closeable. * Fixed the DirectoryEditor to popup the correct file dialog (thanks to Luca Fasano and Phil Thompson) * Fixed a circular import error in Color, Font and RGBColor traits * Fixed a bug in the ColorEditor that was causing the revert action to not work correctly. * Fixed a bug that caused a traceback when trying to undock a pyface dock window * Fixed a bug in the 'livemodal' view that caused the UI to become unresponsive if the 'updated' event was fired on the contained view. * Fixed bugs in ListEditor (notebook style) that caused a loss of sync between the 'selected' trait and the activated dock window.

After months of use in production and about two months of public testing for 1.0, Paver 1.0 has been released. The changes between Paver 0.8.1, the most recent stable release, and 1.0 are quite significant. Paver 1.0 is easier, cleaner, less magical and just better all around. The backwards compatibility breaks should be easy enough to work around, are described in DeprecationWarnings and were introduced in 1.0a1 back in January. Paver's home page: http://www.blueskyonmars.com/projects/paver/ What is Paver? =========== Paver is a Python-based software project scripting tool along the lines of Make or Rake. It is not designed to handle the dependency tracking requirements of, for example, a C program. It *is* designed to help out with all of your other repetitive tasks (run documentation generators, moving files about, downloading things), all with the convenience of Python's syntax and massive library of code. If you're developing applications in Python, you get even more... Most public Python projects use distutils or setuptools to create source tarballs for distribution. (Private projects can take advantage of this, too!) Have you ever wanted to generate the docs before building the source distribution? With Paver, you can, trivially. Here's a complete pavement.py:: from paver.easy import * from paver.setuputils import setup setup( name="MyCoolProject", packages=['mycool'], version="1.0", url="http://www.blueskyonmars.com/", author="Kevin Dangoor", author_email="dangoor(a)gmail.com" ) @task @needs(['html', "distutils.command.sdist"]) def sdist(): """Generate docs and source distribution.""" pass With that pavement file, you can just run ``paver sdist``, and your docs will be rebuilt automatically before creating the source distribution. It's also easy to move the generated docs into some other directory (and, of course, you can tell Paver where your docs are stored, if they're not in the default location.) Installation ------------ The easiest way to get Paver is if you have setuptools_ installed. ``easy_install Paver`` Without setuptools, it's still pretty easy. Download the Paver .tgz file from `Paver's Cheeseshop page`_, untar it and run: ``python setup.py install`` .. _Paver's Cheeseshop page: http://pypi.python.org/pypi/Paver/ .. _setuptools: http://peak.telecommunity.com/DevCenter/EasyInstall Help and Development -------------------- You can get help from the `mailing list`_. If you'd like to help out with Paver, you can check the code out from Googlecode: ``svn checkout http://paver.googlecode.com/svn/trunk/ paver-read-only`` You can also take a look at `Paver's project page on Googlecode < http://code.google.com/p/paver/>`_. .. _mailing list: http://groups.google.com/group/paver -- Kevin Dangoor work: http://labs.mozilla.com/ email: kid(a)blazingthings.com blog: http://www.BlueSkyOnMars.com

lxml 2.2 released
by Stefan Behnel 21 Mar '09

21 Mar '09

Hi all, I'm proud to announce the release of lxml 2.2 final. http://codespeak.net/lxml/ http://pypi.python.org/pypi/lxml/2.2 This is a major new, stable and mature release that takes over the stable 2.x release series. All previous 2.x releases are now officially out of maintenance. It includes a large number of bug fixes and improvements (see below for a complete changelog) that make lxml 2.2 a lot more robust than the previous 2.1 and older releases. It is therefore generally worth upgrading (and it should not be too hard to do that). This release was built with Cython 0.11 final. Have fun, Stefan What is lxml? ============== lxml is the most feature-rich and easy-to-use library for working with XML and HTML in the Python language. It's also amongst the fastest and most memory friendly XML tree libraries for Python. lxml is a pythonic, mature binding for the libxml2 and libxslt libraries that provides safe and convenient access to these libraries using the ElementTree API. It extends the ElementTree API significantly to offer support for XPath, RelaxNG, XML Schema, XSLT, C14N and much more. Changelog since lxml 2.1 ========================= 2.2 (2009-03-21) Features added * Support for standalone flag in XML declaration through tree.docinfo.standalone and by passing standalone=True/False on serialisation. Bugs fixed * Crash when parsing an XML Schema with external imports from a filename. 2.2beta4 (2009-02-27) Features added * Support strings and instantiable Element classes as child arguments to the constructor of custom Element classes. * GZip compression support for serialisation to files and file-like objects. Bugs fixed * Deep-copying an ElementTree copied neither its sibling PIs and comments nor its internal/external DTD subsets. * Soupparser failed on broken attributes without values. * Crash in XSLT when overwriting an already defined attribute using xsl:attribute. * Crash bug in exception handling code under Python 3. This was due to a problem in Cython, not lxml itself. * lxml.html.FormElement._name() failed for non top-level forms. * TAG special attribute in constructor of custom Element classes was evaluated incorrectly. Other changes * Official support for Python 3.0.1. * Element.findtext() now returns an empty string instead of None for Elements without text content. 2.2beta3 (2009-02-17) Features added * XSLT.strparam() class method to wrap quoted string parameters that require escaping. Bugs fixed * Memory leak in XPath evaluators. * Crash when parsing indented XML in one thread and merging it with other documents parsed in another thread. * Setting the base attribute in lxml.objectify from a unicode string failed. * Fixes following changes in Python 3.0.1. * Minor fixes for Python 3. Other changes * The global error log (which is copied into the exception log) is now local to a thread, which fixes some race conditions. * More robust error handling on serialisation. 2.2beta2 (2009-01-25) Bugs fixed * Potential memory leak on exception handling. This was due to a problem in Cython, not lxml itself. * iter_links (and related link-rewriting functions) in lxml.html would interpret CSS like url("link") incorrectly (treating the quotation marks as part of the link). * Failing import on systems that have an io module. 2.2beta1 (2008-12-12) Features added * Allow lxml.html.diff.htmldiff to accept Element objects, not just HTML strings. Bugs fixed * Crash when using an XPath evaluator in multiple threads. * Fixed missing whitespace before Link:... in lxml.html.diff. Other changes * Export lxml.html.parse. 2.2alpha1 (2008-11-23) Features added * Support for XSLT result tree fragments in XPath/XSLT extension functions. * QName objects have new properties namespace and localname. * New options for exclusive C14N and C14N without comments. * Instantiating a custom Element classes creates a new Element. Bugs fixed * XSLT didn't inherit the parse options of the input document. * 0-bytes could slip through the API when used inside of Unicode strings. * With lxml.html.clean.autolink, links with balanced parenthesis, that end in a parenthesis, will be linked in their entirety (typical with Wikipedia links).

ANN: eGenix mxODBC Connect 1.0.1 - Python Database Interface
by eGenix Team: M.-A. Lemburg 19 Mar '09

19 Mar '09

________________________________________________________________________ ANNOUNCING eGenix.com mxODBC Connect Python Database Interface Version 1.0.1 Our new client-server product for connecting Python applications to relational databases - from all major platforms This announcement is also available on our web-site for online reading: http://www.egenix.com/company/news/eGenix-mxODBC-Connect-1.0.1-GA.html ________________________________________________________________________ INTRODUCTION The mxODBC Connect Database Interface for Python allows users to easily connect Python applications to all major databases on the market today in a highly portable and convenient way. Unlike our mxODBC Python extension, mxODBC Connect is designed as client-server application, so you no longer need to find production quality ODBC drivers for all the platforms you target with your Python application. Instead you use an easy to install Python client library which connects directly to the mxODBC Connect database server over the network. This makes mxODBC Connect the ideal basis for writing cross-platform database programs and utilities in Python, especially if you run applications that need to communicate with databases such as MS SQL Server and MS Access, Oracle Database, IBM DB2 and Informix, Sybase ASE and Sybase Anywhere, MySQL, PostgreSQL, SAP MaxDB and many more, that run on Windows or Linux machines. By removing the need to install and configure ODBC drivers on the client side, mxODBC Connect greatly simplifies setup and configuration of database driven client applications, while at the same time making the network communication between client and database server more efficient and more secure. For more information, please see the product page: http://www.egenix.com/products/python/mxODBCConnect/ ________________________________________________________________________ NEWS mxODBC Connect 1.0.1 is a patch-level release of our new mxODBC Connect product. * More Robust We have made the client and server more robust in case of communication failures. Even if the client applications fail to shutdown the server connection before exiting, the server will free up resources used by the client on the server side and rollback transactions as necessary. * More Platform Support With the 1.0.1 release we are also providing much better platform support for the mxODBC Connect Client: we have fixed a problem in 1.0.0 that prevented the installation of the pre-built clients on non-Linux systems. The mxODBC Connect Client can now be installed on most platforms supported by Python, since it is written in a platform independent, portable way. The pre-built archives also make it possible to integrate the clients into build system such as buildout (used in Zope and Plone) or other distutils-based deployment systems. * Ideal for Building Bridges As a result, connecting from e.g. Mac OS X to an SQL Server database has never been easier. You can even keep the data sources you already have configured on your Windows machine and connect to them as if your application were running on the database server itself. ________________________________________________________________________ UPGRADING You are encouraged to upgrade to this latest mxODBC Connect release. When upgrading, please always upgrade both the server and the client installations to the same version - even for patch level releases. Customers who have purchased mxODBC Connect 1.0 licenses can download and upgrade their existing installations without having to purchase new licenses or upgrades. The licenses will continue to work with version 1.0.1. Users of our stand-alone mxODBC product will have to purchase new licenses from our online shop in order to use mxODBC Connect. You can request 30-day evaluation licenses by visiting our web-site or writing to sales(a)egenix.com, stating your name (or the name of the company) and the number of eval licenses that you need. http://www.egenix.com/products/python/mxODBCConnect/#Evaluation ________________________________________________________________________ DOWNLOADS The download archives as well as instructions for installation and configuration of the product can be found on the product page: http://www.egenix.com/products/python/mxODBCConnect/ Evaluation licenses for the server part are available free of charge: http://www.egenix.com/products/python/mxODBCConnect/#Evaluation The client part of mxODBC Connect is always free of charge. _______________________________________________________________________ SUPPORT Commercial support for this product is available from eGenix.com.

It is based on the winning design from Ka-Ping Yee in the Software Carpentry "Track" design competition. Note: Ping is not responsible for this project. The contact for this project is richard(a)users.sourceforge.net. Roundup manages a number of issues (with flexible properties such as "description", "priority", and so on) and provides the ability to: (a) submit new issues, (b) find and edit existing issues, and (c) discuss issues with other participants. The system will facilitate communication among the participants by managing discussions and notifying interested parties when issues are edited. One of the major design goals for Roundup that it be simple to get going. Roundup is therefore usable "out of the box" with any python 2.3+ installation. It doesn't even need to be "installed" to be operational, though a disutils-based install script is provided. It comes with two issue tracker templates (a classic bug/feature tracker and a minimal skeleton) and four database back-ends (anydbm, sqlite, mysql and postgresql).

[Announce] PyGooCanvas 0.14.0
by Gian Mario Tagliaretti 17 Mar '09

17 Mar '09

I am pleased to announce version 0.14.0 of the Python bindings for Goocanvas. It is available at: http://download.gnome.org/sources/pygoocanvas/0.14/ The bindings are updated with the new Goocanvas API PyGooCanvas 0.14.0 (Mar 17 2009) ================== o Update the docs with new goocanvas API and some random fixes (Gian Mario) o Add an export SVG function in the demo (Gian Mario) Blurb: ====== Goocanvas [1] is a canvas widget for GTK+, It is similar in many ways to FooCanvas, hence the name, but it uses cairo for rendering, it has an optional model/view split, and uses interfaces for items & views (so you can easily turn any application object into a canvas item or view). PyGooCanvas is a wrapper which exposes the goocanvas API to the python world. It is fairly complete; most of the API are covered. The documentation is done, anyway bug reports on docs are really important to improve the documentation. Like the GTK+ library, PyGTK and GooCanvas itself PyGooCanvas is licensed under the GNU LGPL, so is suitable for use in both free software and proprietary applications. PyGooCanvas requires: ===================== o Goocanvas >= 0.14 o PyGObject >= 2.10.1 (2.11.3 to build the docs) o PyGTK >= 2.10.4 (2.12.0 to use gtk.Tooltip) o PyCairo >= 1.4.0 Bug reports should go to http://bugzilla.gnome.org/browse.cgi?product=pygoocanvas [1] http://live.gnome.org/GooCanvas cheers -- Gian Mario Tagliaretti GNOME Foundation member gianmt(a)gnome.org

Sphinx 0.6 and 0.5.2, beta 1, released
by Georg Brandl 16 Mar '09

16 Mar '09

Hi all, I'm proud to announce the release of Sphinx 0.6b1 and 0.5.2b1. Sphinx 0.5.2 is a bugfix-only release in the 0.5 series, while 0.6 is a feature release, containing all of 0.5.2's fixes together with many added features. These are beta releases, so please test them out and report any bugs to sphinx-dev(a)googlegroups.com or the tracker at <http://bitbucket.org/birkenfeld/sphinx/>. Thank you! The finals will be out in a week's time, if no severe problems are uncovered. What is it? =========== Sphinx is a tool that makes it easy to create intelligent and beautiful documentation for Python projects (or other documents consisting of multiple reStructuredText source files). Websites: 0.5 series <http://sphinx.pocoo.org/> 0.6 series <http://sphinx.pocoo.org/latest/> What's new in 0.6 (short version)? ================================== Long version: http://sphinx.pocoo.org/latest/changes.html * General/Markup: - Templating now requires the Jinja2 library, which is an enhanced version of the old Jinja1 engine. - Theming support, see the new section in the documentation. - Due to popular demand, added a ``:doc:`` role which directly links to another document without the need of creating a label to which a ``:ref:`` could link to. - Added a ``:download:`` role that marks a non-document file for inclusion into the HTML output and links to it. - Added an ``only`` directive that can selectively include text based on enabled "tags". Tags can be given on the command line. Also, the current builder output format (e.g. "html" or "latex") is always a defined tag. - Added HTML section numbers, enabled by giving a ``:numbered:`` flag to the ``toctree`` directive. - The ``literalinclude`` directive now supports several more options, to include only parts of a file. - The ``toctree`` directive now supports a ``:hidden:`` flag, which will prevent links from being generated in place of the directive -- this allows you to define your document structure, but place the links yourself. - Paths to images, literal include files and download files can now be absolute (like ``/images/foo.png``). They are treated as relative to the top source directory. - SVG images are now supported in HTML (via ``<object>`` and ``<embed>`` tags). * Configuration: - The new config value ``rst_epilog`` can contain reST that is appended to each source file that is read. This is the right place for global substitutions. - The new ``html_add_permalinks`` config value can be used to switch off the generated "paragraph sign" permalinks for each heading and definition environment. - The new ``html_show_sourcelink`` config value can be used to switch off the links to the reST sources in the sidebar. - The default value for ``htmlhelp_basename`` is now the project title, cleaned up as a filename. - The new ``modindex_common_prefix`` config value can be used to ignore certain package names for module index sorting. - The new ``trim_footnote_reference_space`` config value mirrors the docutils config value of the same name and removes the space before a footnote reference that is necessary for reST to recognize the reference. - The new ``latex_additional_files`` config value can be used to copy files (that Sphinx doesn't copy automatically, e.g. if they are referenced in custom LaTeX added in ``latex_elements``) to the build directory. * Builders: - The new ``DirectoryHTMLBuilder`` (short name ``dirhtml``) creates a separate directory for every page, and places the page there in a file called ``index.html``. Therefore, page URLs and links don't need to contain ``.html``. - The new ``html_link_suffix`` config value can be used to select the suffix of generated links between HTML files. - #96: The LaTeX builder now supports figures wrapped by text, when using the ``figwidth`` option and right/left alignment. * New translations: - Italian by Sandro Dentella. - Ukrainian by Petro Sasnyk. - Finnish by Jukka Inkeri. * Extensions and API: - New ``graphviz`` extension to embed graphviz graphs. - New ``inheritance_diagram`` extension to embed... inheritance diagrams! - New ``autosummary`` extension that generates summaries of modules and automatic documentation of modules. - Autodoc now has a reusable Python API, which can be used to create custom types of objects to auto-document (e.g. Zope interfaces). See also ``Sphinx.add_autodocumenter()``. - Autodoc now handles documented attributes. - Autodoc now handles inner classes and their methods. - Autodoc can document classes as functions now if explicitly marked with `autofunction`. - Autodoc can now exclude single members from documentation via the ``exclude-members`` option. - Autodoc can now order members either alphabetically (like previously) or by member type; configurable either with the config value ``autodoc_member_order`` or a ``member-order`` option per directive. * New command-line features: - Config overrides for single dict keys can now be given on the command line. - Source links in HTML are now generated with ``rel="nofollow"``. - Quickstart can now generate a Windows ``make.bat`` file. - There is now a ``-w`` option for sphinx-build that writes warnings to a file, in addition to stderr. - There is now a ``-W`` option for sphinx-build that turns warnings into errors. cheers, Georg

Lepton particle engine 0.9a released
by Casey Duncan 16 Mar '09

16 Mar '09

It is again my pleasure to announce the latest version of the Lepton particle engine for Python. Some important new features, bug fixes and examples are in this new release, and I encourage you to check it out. Here's the lowdown from the change list: - Fix reference leaks in particle emission and domain generate methods - Plane domains are now proper half-space geometries so they support __contains__, which means they can be used with the Collector controller. - Implement Point domain. - Implement arbitrarily orientable Disc, Cylinder and Cone domains. - Add tunnel example. - Implement new closest_point_to() methods for various domains. - Fix distribution of points generated in a Sphere domain with a nonzero inner radius. - Refactor renderer/group binding to avoid circrefs and an infinite loop bug. This also simplifies the API. Thanks to Ken Lauer for the report. - Fix color bug in the billboard renderer, thanks again to Ken Lauer. - Add ParticleSystem.run_ahead() method to warm up the particle system or "fast forward" the simulation. - Add Magnet controller and example. Thanks to Andrew Charles for the initial implementation of these. - Various code cleanups and fixes for building on Windows. Thanks to Jussi Lepistö. Get it Here ========= http://code.google.com/p/py-lepton/ http://pypi.python.org/pypi/lepton/ What is Lepton, Exactly? ==================== Lepton is a high-performance, pluggable particle engine and API for Python. It is designed for creating graphical special effects for games or other visual applications. The engine is designed to be very flexible and does not rely on any other libraries directly. You can use it either with OpenGL (via pyglet, PyOpenGL, wxPython, etc), or with pygame by selecting the appropriate renderer. Examples are provided using pyglet and pygame. If you have questions or comments or would like to contribute, you can join the google group at: http://groups.google.com/group/py-lepton-users Enjoy. -Casey

[ANNOUNCE] bzr 1.13 released
by Bob Tanner 15 Mar '09

15 Mar '09

This release includes bug fixes and a few performance and feature improvements. GNU Changelog output can now be produced by ``bzr log --format gnu- changelog``. Debug flags can now be set in ``~/.bazaar/bazaar.conf``. Lightweight Checkouts and Stacked Branches should both be much faster over remote connections. The Bazaar team is happy to announce availability of a new release of the bzr adaptive version control system. Thanks to everyone who contributed patches, suggestions, and feedback. Bazaar is now available for download from http://bazaar-vcs.org/Download as a source tarball; packages for various systems will be available soon. bzr 1.13 "paraskavedekatriaphobia" 2009-03-14 ----------------------------------------------------------------- CHANGES FROM bzr 1.13rc1 2009-03-10: BUG FIXES: * Fix "is not a stackable format" error when pushing a stackable-format branch with an unstackable-format repository to a destination with a default stacking policy. (Andrew Bennetts) * Progress bars now show the rate of network activity for ``bzr+ssh://`` and ``bzr://`` connections. (Andrew Bennetts) COMPATIBILITY BREAKS: * ``bzr log --line`` now indicates which revisions are merges with `[merge]` after the date. Scripts which parse the output of this command may need to be adjusted. (Neil Martinsen-Burrell) NEW FEATURES: * ``bzr reconfigure`` now supports --with-trees and --with-no-trees options to change the default tree-creation policy of shared repositories. (Matthew Fuller, Marius Kruger, #145033) * Debug flags can now be set in ``~/.bazaar/bazaar.conf``. (Martin Pool) * Filtered views provide a mask over the tree so that users can focus on a subset of a tree when doing their work. See ``Filtered views`` in chapter 7 of the User Guide and ``bzr help view`` for details. (Ian Clatworthy) * GNU Changelog output can now be produced by ``bzr log --format gnu-changelog``. (Andrea Bolognani, Martin Pool) * The ``-Dmemory`` flag now gives memory information on Windows. (John Arbash Meinel) * Multiple authors for a commit can now be recorded by using the "--author" option multiple times. (James Westby, #185772) * New clean-tree command, from bzrtools. (Aaron Bentley, Jelmer Vernoij) * New command ``bzr launchpad-open`` opens a Launchpad web page for that branch in your web browser, as long as the branch is on Launchpad at all. (Jonathan Lange) IMPROVEMENTS: * ``bzr add`` no longer prints ``add completed`` on success. Failure still prints an error message. (Robert Collins) * ``bzr branch`` now has a ``--no-tree`` option which turns off the generation of a working tree in the new branch. (Daniel Watkins, John Klinger, #273993) * Bazaar will now point out ``bzr+ssh://`` to the user when they use ssh://. (Jelmer Vernooij, #330535) * ``bzr -v info`` now omits the number of committers branch statistic, making it many times faster for large projects. To include that statistic in the output, use ``bzr -vv info``. (Ian Clatworthy) * ``bzr push`` to a ``bzr`` url (``bzr://``, ``bzr+ssh://`` etc) will stream if the server is version 1.13 or greater, reducing roundtrips significantly. (Andrew Bennetts, Robert Collins) * Lightweight Checkouts and Stacked Branches should both be much faster over remote connections. Building the working tree now batches up requests into approx 5MB requests, rather than a separate request for each file. (John Arbash Meinel) * Support for GSSAPI authentication when using HTTP or HTTPS. (Jelmer Vernooij) * The ``bzr shelve`` prompt now includes a '?' help option to explain the short options better. (Daniel Watkins, #327429) * ``bzr lp-open`` now falls back to the push location if it cannot find a public location. (Jonathan Lange, #332372) * ``bzr lp-open`` will try to find the Launchpad URL for the location passed on the command line. This makes ``bzr lp-open lp:foo`` work as expected. (Jonathan Lange, #332705) * ``bzr send`` now supports MH-E via ``emacsclient``. (Eric Gillespie) BUG FIXES: * Bazaar now gives a better message including the filename if it's unable to read a file in the working directory, for example because of a permission error. (Martin Pool, #338653) * ``bzr send`` help is more specific about how to apply merge directives. (Neil Martinsen-Burrell, #253470) * ``bzr missing`` now uses ``Repository.get_revision_delta()`` rather than fetching trees and determining a delta itself. (Jelmer Vernooij, #315048) * ``bzr push`` to a smart server no longer causes "Revision {set([('null:',)])} not present ..." errors when the branch has multiple root revisions. (Andrew Bennetts, #317654) * ``bzr shelve`` now properly handle patches with no terminating newline. (Benoît PIERRE, #303569) * ``bzr unshelve`` gives a more palatable error if passed a non- integer shelf id. (Daniel Watkins) * Export now handles files that are not present in the tree. (James Westby, #174539) * Fixed "sprout() got an unexpected keyword argument 'source_branch'" error branching from old repositories. (Martin Pool, #321695) * Make ``bzr push --quiet <non-local location>`` less chatty. (Kent Gibson, #221461) * Many Branch hooks would not fire with ``bzr://`` and ``bzr +ssh://`` branches, and this was not noticed due to a bug in the test logic for branches. This is now fixed and a test added to prevent it reoccuring. (Robert Collins, Andrew Bennetts) * Restore the progress bar on Windows. We were disabling it when TERM wasn't set, but Windows doesn't set TERM. (Alexander Belchenko) * ``setup.py build_ext`` now gives a proper error when an extension fails to build. (John Arbash Meinel) * Symlinks to non ascii file names are now supported. (Robert Collins, Vincent Ladeuil, #339055, #272444) * Under rare circumstances (aka nobody reported a bug about it), the ftp transport could revert to ascii mode. It now stays in binary mode except when needed. (Vincent Ladeuil) * Unshelve does not generate warnings about progress bars. (Aaron Bentley, #328148) DOCUMENTATION: * Added ``Organizing your workspace`` to the User Guide appendices, summarizing some common ways of organizing trees, branches and repositories and the processes/workflows implied/enabled by each. (Ian Clatworthy) * Hooks can now be self documenting. ``bzrlib.hooks.Hooks.create_hook`` is the entry point for this feature. (Robert Collins) * The documentation for ``shelve`` and ``unshelve`` has been clarified. (Daniel Watkins, #327421, #327425) API CHANGES: * ``bzr selftest`` now fails if the bazaar sources contain trailing whitespace, non-unix style line endings and files not ending in a newline. About 372 files and 3243 lines with trailing whitespace was updated to comply with this. The code already complied with the other criteria, but now it is enforced. (Marius Kruger) * ``Branch.fetch`` and ``Repository.fetch`` now return None rather than a count of copied revisions and failed revisions. A while back we stopped ever reporting failed revisions because we started erroring instead, and the copied revisions count is not used in the UI at all - indeed it only reflects the repository status not changes to the branch itself. (Robert Collins) * MutableTree.commit now favours the "authors" argument, with the old "author" argument being deprecated. * Remove deprecated EmptyTree. (Martin Pool) * ``Repository.fetch`` now accepts an optional ``fetch_spec`` parameter. A ``SearchResult`` or ``MiniSearchResult`` may be passed to ``fetch_spec`` instead of a ``last_revision`` to specify exactly which revisions to fetch. (Andrew Bennetts) * ``RepositoryAcquisitionPolicy.acquire_repository`` now returns a tuple of ``(repository, is_new_flag)``, rather than just the repository. (Andrew Bennetts) * Revision.get_apparent_author() is now deprecated, replaced by Revision.get_apparent_authors(), which returns a list. The former now returns the first item that would be returned from the second. * The ``BranchBuilder`` test helper now accepts a ``timestamp`` parameter to ``build_commit`` and ``build_snapshot``. (Martin Pool) * The ``_fetch_*`` attributes on ``Repository`` are now on ``RepositoryFormat``, more accurately reflecting their intent (they describe a disk format capability, not state of a particular repository of that format). (Robert Collins) INTERNALS: * Branching from a non-stacked branch on a smart protocol is now free of virtual file system methods. (Robert Collins, Andrew Bennetts) * Branch and Repository creation on a bzr+ssh://server are now done via RPC calls rather than VFS calls, reducing round trips for pushing new branches substantially. (Robert Collins) * ``Branch.clone`` now takes the ``repository_policy`` formerly used inside ``BzrDir.clone_on_transport``, allowing stacking to be configured before the branch tags and revision tip are set. This fixes a race condition cloning stacked branches that would cause plugins to have hooks called on non-stacked instances. (Robert Collins, #334187) * ``BzrDir.cloning_metadir`` now has a RPC call. (Robert Collins) * ``BzrDirFormat.__str__`` now uses the human readable description rather than the sometimes-absent disk label. (Robert Collins) * ``bzrlib.fetch`` is now composed of a sender and a sink component allowing for decoupling over a network connection. Fetching from or into a RemoteRepository with a 1.13 server will use this to stream the operation. (Andrew Bennetts, Robert Collins) * ``bzrlib.tests.run_suite`` accepts a runner_class parameter supporting the use of different runners. (Robert Collins) * Change how file_ids and revision_ids are interned as part of inventory deserialization. Now we use the real ``intern()``, rather than our own workaround that would also cache a Unicode copy of the string, and never emptied the cache. This should slightly reduce memory consumption. (John Arbash Meinel) * New branch method ``create_clone_on_transport`` that returns a branch object. (Robert Collins) * New hook Commands['extend_command'] to allow plugins to access a command object before the command is run (or help generated from it), without overriding the command. (Robert Collins) * New version of the ``BzrDir.find_repository`` verb supporting ``_network_name`` to support removing more _ensure_real calls. (Robert Collins) * ``RemoteBranchFormat`` no longer claims to have a disk format string. (Robert Collins) * ``Repository`` objects now have ``suspend_write_group`` and ``resume_write_group`` methods. These are currently only useful with pack repositories. (Andrew Bennetts, Robert Collins) * ``BzrDirFormat``, ``BranchFormat`` and ``RepositoryFormat`` objects now have a ``network_name`` for passing the format across RPC calls. (Robert Collins, Andrew Bennetts) * ``RepositoryFormat`` objects now all have a new attribute ``_serializer`` used by fetch when reserialising is required. (Robert Collins, Andrew Bennetts) * Some methods have been pulled up from ``BzrBranch`` to ``Branch`` to aid branch types that are not bzr branch objects (like RemoteBranch). (Robert Collins, Andrew Bennetts) * Test adaptation has been made consistent throughout the built in tests. ``TestScenarioApplier``, ``multiply_tests_from_modules``, ``adapt_tests``, ``adapt_modules`` have all been deleted. Please use ``multiply_tests``, or for lower level needs ``apply_scenarios`` and ``apply_scenario``. (Robert Collins) * ``TestSkipped`` is now detected by TestCase and passed to the ``TestResult`` by calling ``addSkip``. For older TestResult objects, where ``addSkip`` is not available, ``addError`` is still called. This permits test filtering in subunit to strip out skipped tests resulting in a faster fix-shrink-list-run cycle. This is compatible with the testtools protocol for skips. (Robert Collins) * The ``_index`` of ``KnitVersionedFiles`` now supports the ability to scan an underlying index that is going to be incorporated into the ``KnitVersionedFiles`` object, to determine if it has missing delta references. The method is ``scan_unvalidated_index``. (Andrew Bennetts, Robert Collins) * There is a RemoteSink object which handles pushing to smart servers. (Andrew Bennetts, Robert Collins) * ``TransportTraceDecorator`` now logs ``put_bytes_non_atomic`` and ``rmdir`` calls. (Robert Collins) * ``VersionedFiles`` record adapters have had their signature change from ``(record, record.get_bytes_as(record.storage_kind))`` to ``(record)`` reducing excess duplication and allowing adapters to access private data in record to obtain content more efficiently. (Robert Collins) * We no longer probe to see if we should create a working tree during clone if we cannot get a local_abspath for the new bzrdir. (Robert Collins) bzr 1.12 "1234567890" 2009-02-13 -------------------------------- This release of Bazaar contains many improvements to the speed, documentation and functionality of ``bzr log`` and the display of logged revisions by ``bzr status``. bzr now also gives a better indication of progress, both in the way operations are drawn onto a text terminal, and by showing the rate of network IO. BUG FIXES: * ``bzr init --development-wt5[-rich-root]`` would fail because of circular import errors. (John Arbash Meinel, #328135) DOCUMENTATION: * Expanded the help for log and added a new help topic called ``log-formats``.
