pywinauto 0.3.8 released - collection of changes from the last two years
by Mark Mc Mahon March 15, 2009

March 15, 2009

Hi, The 0.3.8 release of pywinauto is now available. pywinauto is a set of open-source (LGPL) modules for using Python as a GUI automation 'driver' for Windows NT based Operating Systems (NT/W2K/XP). SourceForge project page: http://sourceforge.net/projects/pywinauto Download from SourceForge http://sourceforge.net/project/showfiles.php?group_id=157379 Here is the list of changes from 0.3.7: 0.3.8 Collecting improvements from last 2 years ------------------------------------------------------------------ 15-March-2009 * Fixed toolbar button pressing - This required for HwndWrapper.NotifyParent() to be updated (to accept a new ID parameter) * Fixed a bug wherea listview without a column control would make pywinauto fail to capture the dialog. * Converted documenation from Pudge generated to Sphinx Generated * Added some baic support for Pager and Progress controls (no tests yet) * Added some more VB 'edit' window classes * Added some more VB 'listbox' window classes * Added some more VB 'button' window classes * Ensured that return value from ComboBoxWrapper.SelectedIndices is always a tuple (there was a bug where it would sometimes be a ctypes array) * Changed default for finding windows to find disabled windows as well as enabled ones (previous was to find enabled windows only) (note this may impact scripts that relied on the previous setting i.e. in cases where two dialogs have the same title!) * Much better handling of InvalidWindowHandle during automation runs. This could be raised when a closing window is still available when the automation was called, but is gone half way through whatever function was called. * Made clicking more robust by adding a tiny wait between each SendMessageTimeout in _perform_click(). * Added attributes ``can_be_label`` and ``has_title`` to ``HwndWrapper`` and subclasses to specify whether a control can act as a label for other controls, and whether the title should be used for identifying the control. If you have created your own HwndWrapper subclasses you may need to override the defaults. * Added a ``control_id`` parameter to find_windows which allows finding windows based off of their control id's * Added a FriendlyClassName method to MenuItem * Split up the functions for button truncation data * Commented out code to get a new font if the font could not be recovered * Moved code to get the control font from Truncation test to handleprops * Added a function to get the string representation of the bug. (need to refactor PrintBugs at some point). * Fixed a variable name (from fname -> font_attrib as fname was not a defined variable!) * Forced some return values from MissingExtraString test to be Unicode * Fixed the MiscValues test (converted to Unicode and removed some extraneous characters) * Updated the path for all unittests * Made two unit tests sligthly more robust and less dependent on computer/app settings * Updated timing settings for unit tests * Updated the examples to work in dev environment.

Cython 0.11 Released
by Robert Bradshaw March 14, 2009

March 14, 2009

The Python compiler Cython 0.11 was just released. We would like to thank Stefan Behnel, Robert Bradshaw, Ondrej Certik, Lisandro Dalcin, Jason Evans, Magnus Lie Hetland, Hoyt Koepke, and Dag Sverre Seljebotn who contributed code to this release, as well as the many others who contributed ideas, bug reports, and feedback. What is Cython? ===================== Cython is a language that makes writing C extensions for the Python language as easy as Python itself. Cython is based on the well-known Pyrex, but supports more cutting edge functionality and optimizations. The Cython language is very close to the Python language, but Cython additionally supports calling C functions and declaring C types on variables and class attributes. This allows the compiler to generate very efficient C code from Cython code. This makes Cython the ideal language for wrapping for external C libraries, and for fast C modules that speed up the execution of Python code. Where to get it? ===================== http://cython.org/ http://pypi.python.org/pypi/Cython/ Release Notes ===================== The majority of changes in this version are internal, the largest of which is moving most temp allocation to the code generation phase which has several advantages and will greatly facilitate future development. In conjunction with this, Dag Sverre Seljebotn wrote a "reference counting nanny" which, when enabled, warns of potential double-frees and memory-leaks. Though it will not find memory leaks in user code (malloc is just as dangerous as ever) it is a great tool for verifying that Cython itself is outputting correct code and is an invaluable consistency check during the many changes we've been making to temporary variable handling. There have also been many improvements for developers--for example, the parse tree is printed on compiler crashes, the testing framework has been enhanced, and there is a mode to produce output files interlaced with the compiler's call stacks to more easily trace what's going on. The most visible new user-level features are size_t as a native type (as part of Lisandro Dalcin's cleanup and improvement of Python <-> C type conversions) and proper Python semantics for optimized range() loops (Magnus Lie Hetland). C(p)def functions can now take decorators, though only @cython.locals is currently supported, and inline functions can appear in .pxd files. There were also numerious bug fixes, optimizations, and general code cleanups that happened in this release too. A list of closed tickets can be found at http://trac.cython.org/ cython_trac/query?group=component&milestone=0.11 . Though not every change is associated to a trac ticket, we plan to be more stringent about this in the future. We have several patches already done that didn't make it into 0.11, and so 0.11.1 will be out soon.

Roundup Issue Tracker release 1.4.7
by Richard Jones March 13, 2009

March 13, 2009

I'm proud to release version 1.4.7 of Roundup. 1.4.7 is primarily a bugfix release which contains important security fixes: - a number of security issues were discovered by Daniel Diniz - EditCSV and ExportCSV altered to include permission checks - HTTP POST required on actions which alter data - HTML file uploads served as application/octet-stream - Handle Unauthorised in file serving correctly - New item action reject creation of new users - Item retirement was not being controlled - Roundup is now compatible with Python 2.6 - Improved French and German translations - Improve consistency of item sorting in HTML interface - Various other small bug fixes, robustification and optimisation Though some new features made it in also: - Provide a "no selection" option in web interface selection widgets - Debug logging now uses the logging module rather than print - Allow CGI frontend to serve XMLRPC requests. - Added XMLRPC actions, as well as bridging CGI actions to XMLRPC actions. - Optimized large file serving via mod_python / sendfile(). - Support resuming downloads for (large) files. If you're upgrading from an older version of Roundup you *must* follow the "Software Upgrade" guidelines given in the maintenance documentation. Roundup requires python 2.3 or later for correct operation. To give Roundup a try, just download (see below), unpack and run:: roundup-demo Release info and download page: http://cheeseshop.python.org/pypi/roundup Source and documentation is available at the website: http://roundup.sourceforge.net/ Mailing lists - the place to ask questions: http://sourceforge.net/mail/?group_id=31577 About Roundup ============= Roundup is a simple-to-use and -install issue-tracking system with command-line, web and e-mail interfaces. 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).

[ANN] PyTables 2.1.1 released
by Francesc Alted March 13, 2009

March 13, 2009

=========================== Announcing PyTables 2.1.1 =========================== PyTables is a library for managing hierarchical datasets and designed to efficiently cope with extremely large amounts of data with support for full 64-bit file addressing. PyTables runs on top of the HDF5 library and NumPy package for achieving maximum throughput and convenient use. This is a maintenance release, so you should not expect API changes. Instead, a handful of bugs, like `File` not being subclassable, incorrectly retrieved default values for data types, a memory leak, and more, have been fixed. Besides, some enhancements have been implemented, like improved Unicode support for filenames, better handling of Unicode attributes, and the possibility to create very large data types exceeding 64 KB in size (with some limitations). Last but not least, this is the first PyTables version fully tested against Python 2.6. It is worth noting that binaries for Windows and Python 2.6 wears the newest HDF5 1.8.2 libraries (instead of the traditional HDF5 1.6.x) now. In case you want to know more in detail what has changed in this version, have a look at: http://www.pytables.org/moin/ReleaseNotes/Release_2.1.1 You can download a source package with generated PDF and HTML docs, as well as binaries for Windows, from: http://www.pytables.org/download/stable For an on-line version of the manual, visit: http://www.pytables.org/docs/manual-2.1.1 You may want to fetch an evaluation version for PyTables Pro from: http://www.pytables.org/download/evaluation Resources ========= About PyTables: http://www.pytables.org About the HDF5 library: http://www.hdfgroup.org/HDF5/ About NumPy: http://numpy.scipy.org/ Acknowledgments =============== Thanks to many users who provided feature improvements, patches, bug reports, support and suggestions. See the ``THANKS`` file in the distribution package for a (incomplete) list of contributors. Most specially, a lot of kudos go to the HDF5 and NumPy (and numarray!) makers. Without them, PyTables simply would not exist. Share your experience ===================== Let us know of any bugs, suggestions, gripes, kudos, etc. you may have. ---- **Enjoy data!** -- The PyTables Team -- Francesc Alted

Concurrence Framework 0.3 Released
by Henk March 13, 2009

March 13, 2009

Concurrence is a framework for creating massively concurrent network applications in Python. It takes a Lightweight-tasks-with-message-passing approach to concurrency. The goal of Concurrence is to provide an easier programming model for writing high performance network applications than existing solutions (Multi-threading, Twisted, asyncore etc). Concurrence uses Lightweight tasks in combination with libevent to expose a high-level synchronous API to low-level asynchronous IO. http://opensource.hyves.org/concurrence/
