py.test-1.3.0: new options, per-plugin hooks, better reporting
by holger krekel May 5, 2010

May 5, 2010

py.test/pylib 1.3.0: new options, per-plugin hooks, fixes ... =========================================================================== The py.test/pylib 1.3.0 release introces new options, bug fixes and improved compatibility with Python3 and Jython-2.5.1 on Windows. If you already use py-1.2 chances are you can just use py-1.3.0. See the below CHANGELOG for more details and http://pylib.org/install.html for installation instructions. py.test is an advanced automated testing tool working with Python2, Python3, Jython and PyPy versions on all major operating systems. It offers a no-boilerplate testing approach and has inspired other testing tools and enhancements in the standard Python library for more than five years. It has a simple and extensive plugin architecture, configurable reporting and provides unique ways to make it fit to your testing process and needs. See http://pytest.org for more info. cheers and have fun, holger krekel Changes between 1.2.1 and 1.3.0 ================================================== - deprecate --report option in favour of a new shorter and easier to remember -r option: it takes a string argument consisting of any combination of 'xfsX' characters. They relate to the single chars you see during the dotted progress printing and will print an extra line per test at the end of the test run. This extra line indicates the exact position or test ID that you directly paste to the py.test cmdline in order to re-run a particular test. - allow external plugins to register new hooks via the new pytest_addhooks(pluginmanager) hook. The new release of the pytest-xdist plugin for distributed and looponfailing testing requires this feature. - add a new pytest_ignore_collect(path, config) hook to allow projects and plugins to define exclusion behaviour for their directory structure - for example you may define in a conftest.py this method:: def pytest_ignore_collect(path): return path.check(link=1) to prevent even collection of any tests in symlinked dirs. - new pytest_pycollect_makemodule(path, parent) hook for allowing customization of the Module collection object for a matching test module. - extend and refine xfail mechanism: ``(a)py.test.mark.xfail(run=False)`` do not run the decorated test ``(a)py.test.mark.xfail(reason="...")`` prints the reason string in xfail summaries specifiying ``--runxfail`` on command line virtually ignores xfail markers - expose (previously internal) commonly useful methods: py.io.get_terminal_with() -> return terminal width py.io.ansi_print(...) -> print colored/bold text on linux/win32 py.io.saferepr(obj) -> return limited representation string - expose test outcome related exceptions as py.test.skip.Exception, py.test.raises.Exception etc., useful mostly for plugins doing special outcome interpretation/tweaking - (issue85) fix junitxml plugin to handle tests with non-ascii output - fix/refine python3 compatibility (thanks Benjamin Peterson) - fixes for making the jython/win32 combination work, note however: jython2.5.1/win32 does not provide a command line launcher, see http://bugs.jython.org/issue1491 . See pylib install documentation for how to work around. - fixes for handling of unicode exception values and unprintable objects - (issue87) fix unboundlocal error in assertionold code - (issue86) improve documentation for looponfailing - refine IO capturing: stdin-redirect pseudo-file now has a NOP close() method - ship distribute_setup.py version 0.6.10 - added links to the new capturelog and coverage plugins

Announcing IronPython Tools for Visual Studio
by Dave Fugate May 3, 2010

May 3, 2010

Hello Python Community, We are happy to announce the first broadly available release of IronPython Tools for Visual Studio<http://www.ironpython.net/tools/>. IronPython Tools for Visual Studio (IPyTools) is a set of extensions available for Visual Studio 2010 which supports development of IronPython applications. This release is still an early Community Technical Preview (CTP) and builds upon the preview release that we gave exclusively to attendees of PyCon 2010. The release has been updated to run on the final version of Visual Studio 2010 and includes many bug fixes, performance improvements, and new features. This release includes support for Intellisense including member completion, signature help, find all references, and goto definition. It enables quick browsing of your code using the object browser and the editor navigation bar. It has an interactive (REPL) window that enables the development of applications in an interactive way. IPyTools supports lightweight development without a project as well as working with project files in the tradition of Visual Studio . Opening a .py file causes IronPython Tools to model the code in the containing directory as an implicit project for Intellisense features. There are project templates for console, WPF, WinForms, and Silverlight applications. WPF applications support drag-and-drop UI development. Debugging of Python applications works just like you debug other languages in Visual Studio. Changes in this release touch on all the major features of IpyTools. This includes updates to the interactive window, intellisense, the editor, and solutions and projects. We've also made other small tweaks to improve the development experience. The interactive window is one key focus of IpyTools. This release continues to flush out the feature set of the interactive window. We've added a new command to send a snippet of code from the editor into the file context containing the module's code. We've added options to control evaluation of partial expressions for live-object intellisense in the REPL. We've updated the key bindings to for explicitly navigating history in addition to the smart behavior of the arrow keys. Also, the interactive window now supports calls to raw_input() and input(). Finding text in the REPL works now,in addition to a number of other bugs fixed to improve the overall experience. This release also has many updates to intellisense. We've increased the customization options for intellisense so you can now commit completions using enter. There is an option to show the intersection or union of applicable members when multiple types can flow through the code where you are using completion. Related to this, None no longer is considered to be in the intersection of members. We've improved the analysis engine so that it now understands generators, yield expressions, calls to send on a generator, improved analysis of generic method calls, improved tracking of types through calls to list.append/pop/extend/insert, added support for * and ** args, improved analysis of imports, and significantly improved the performance of the analysis engine. We've also cleaned up the display of a number of tooltips including more consistent display of signature completion. We also better track calls on types vs. calls on instances. Finally reference tracking has been improved to include accessing methods (not just calls), tracking references to built-in functions, and added support for some protocol methods such as __getattr__. In addition to this a number of bugs have been fixed. We've also improved the editing experience in this latest release. This includes support for new commands such as comment/uncomment selection, goto matching brace, support for auto indentation, and highlighting matching braces based upon the current caret location. We've added finer control over the editor experience, adding support for disabling outlining on file open. And there are a number of small cleanups such as improving goto definition, making goto definition center the target line on the screen, and fixing method outlining which was improperly collapsing in some cases. Finally we've made some small improvements to the solution and project experience. This includes fixing basic issues such as double clicking on image files now opens them in the VS image editor, project and solutions no longer prompt for saving if they haven't been modified, and we now properly hide hidden files in the solution explorer. We've also improved the experience when invalid values are entered into project settings. For the Silverlight templates we've fixed the issue where Firefox would be launched when IE was the default browser, and we now search for an empty port when launching Chiron for web projects. Altogether this represents a significant improvement over the PyCon release in quality and functionality. But this is still an early preview and as such you may run into issues, and we are looking forward to your feedback both on issues you encounter and the overall feature set. Please see the spec doc for our current and planned features and feel free to comment on any of the contents. We are still working on our final licensing terms for IronPython Tools, and as such this release is licensed under a temporary limited use license. We hope to have nailed down the final licensing terms for the next CTP release. - The IronPython Team

CodeInvestigator 1.0.1 release on April 30
by hans moleman May 2, 2010

May 2, 2010

CodeInvestigator 1.0.1 was released on April 30. I made some changes to the interface and it can now be used with Chrome and IE8. CodeInvestigator is a tracing tool for Python programs. Running a program through CodeInvestigator creates a recording. Program flow, function calls, variable values and conditions are all stored for every line the program executes. The recording is then viewed with an interface consisting of the code. The code can be clicked: A clicked variable displays its value,a clicked loop displays its iterations. You read code, and have at your disposal all the run time details of that code. A computerized desk check tool and another way to learn about your program. http://sourceforge.net/project/showfiles.php?group_id=183942

May 2, 2010

execnet-1.0.6 is a backward compatible release fixing jython/win32 and general race condition issues. execnet is a small, stable and well documented pure-python library for automatically deploying and interacting with clusters of Python interpreters. It seamlessly instantiates remote interpreters through the 'ssh' command line tool or socket connections. It supports interactions between Python 2.4 through to 3.1, Jython-2.5.1 and pypy-c, therefore enabling generic Python-to-Python bridging.
