PyDev 2.2.2 Released
by Fabio Zadrozny 23 Aug '11

23 Aug '11

Hi All, PyDev 2.2.2 has been released Details on PyDev: http://pydev.org Details on its development: http://pydev.blogspot.com Release Highlights: ------------------------------- **IPython / Interactive console** * IPython (0.10 or 0.11) is now used as the interactive console backend if PyDev can detect it in the PYTHONPATH. * While waiting for the output of a command, intermediary results are printed in the console. * ANSI color codes are supported in the interactive console. **Code Analysis** * Reporting variables that shadow builtins as warnings. * Fixed issue where __dict__ was not found. **Code completion** * Aliases have a better treatment (i.e.: unittest.assertEqual will show the proper type/parameters). * Improved support for analyzing function builtins where the return type is known (i.e.: open, str.split, etc). **Debugger** * When doing a remote debug session, if the files cannot be found in the local filesystem, PyDev will ask for files in the remote debugger. **Editor** * Files without extension that have a python shebang (e.g.: #!/usr/bin/python in the first line) are automatically opened with the PyDev editor (in the PyDev Package Explorer). **Django** * When the shell command is used in the django custom commands, PyDev no longer uses 100% cpu while it doesn't complete. **Others** * Fixed issue where the * operator was not properly formatted. * When the quick outline dialog is deactivated, it's closed. * Fixed heuristic for finding position for local import. * Fixed compare editor issue with Eclipse 3.2. * Fixed integration issue with latest PyLint. * Fixed deadlock issue on app engine manage window. * More options added to configure the automatic deletion of .pyc files (delete always, never delete, delete only on .py delete). What is PyDev? --------------------------- PyDev is a plugin that enables users to use Eclipse for Python, Jython and IronPython development -- making Eclipse a first class Python IDE -- It comes with many goodies such as code completion, syntax highlighting, syntax analysis, refactor, debug and many others. Cheers, -- Fabio Zadrozny ------------------------------------------------------ Software Developer Appcelerator http://appcelerator.com/ Aptana http://aptana.com/ PyDev - Python Development Environment for Eclipse http://pydev.org http://pydev.blogspot.com

pytest-2.1.1: assertion fixes and improved junitxml output
by holger krekel 21 Aug '11

21 Aug '11

pytest-2.1.1 is a backward compatible maintenance release of the popular py.test testing tool. See extensive docs with examples here: http://pytest.org/ Most bug fixes address remaining issues with the perfected assertions introduced with 2.1.0 - many thanks to the bug reporters and to Benjamin Peterson for helping to fix them. Also, junitxml output now produces system-out/err tags which lead to better displays of tracebacks with Jenkins. Also a quick note to package maintainers and others interested: there now is a "pytest" man page which can be generated with "make man" in doc/. If you want to install or upgrade pytest, just type one of:: pip install -U pytest # or easy_install -U pytest best, holger krekel / http://merlinux.eu Changes between 2.1.0 and 2.1.1 ---------------------------------------------- - fix issue64 / pytest.set_trace now works within pytest_generate_tests hooks - fix issue60 / fix error conditions involving the creation of __pycache__ - fix issue63 / assertion rewriting on inserts involving strings containing '%' - fix assertion rewriting on calls with a ** arg - don't cache rewritten modules if bytecode generation is disabled - fix assertion rewriting in read-only directories - fix issue59: provide system-out/err tags for junitxml output - fix issue61: assertion rewriting on boolean operations with 3 or more operands - you can now build a man page with "cd doc ; make man"

PyPy 1.6 released
by Maciej Fijalkowski 19 Aug '11

19 Aug '11

======================== PyPy 1.6 - kickass panda ======================== We're pleased to announce the 1.6 release of PyPy. This release brings a lot of bugfixes and performance improvements over 1.5, and improves support for Windows 32bit and OS X 64bit. This version fully implements Python 2.7.1 and has beta level support for loading CPython C extensions. You can download it here: http://pypy.org/download.html What is PyPy? ============= PyPy is a very compliant Python interpreter, almost a drop-in replacement for CPython 2.7.1. It's fast (`pypy 1.5 and cpython 2.6.2`_ performance comparison) due to its integrated tracing JIT compiler. This release supports x86 machines running Linux 32/64 or Mac OS X. Windows 32 is beta (it roughly works but a lot of small issues have not been fixed so far). Windows 64 is not yet supported. The main topics of this release are speed and stability: on average on our benchmark suite, PyPy 1.6 is between **20% and 30%** faster than PyPy 1.5, which was already much faster than CPython on our set of benchmarks. The speed improvements have been made possible by optimizing many of the layers which compose PyPy. In particular, we improved: the Garbage Collector, the JIT warmup time, the optimizations performed by the JIT, the quality of the generated machine code and the implementation of our Python interpreter. .. _`pypy 1.5 and cpython 2.6.2`: http://speed.pypy.org Highlights ========== * Numerous performance improvements, overall giving considerable speedups: - better GC behavior when dealing with very large objects and arrays - **fast ctypes:** now calls to ctypes functions are seen and optimized by the JIT, and they are up to 60 times faster than PyPy 1.5 and 10 times faster than CPython - improved generators(1): simple generators now are inlined into the caller loop, making performance up to 3.5 times faster than PyPy 1.5. - improved generators(2): thanks to other optimizations, even generators that are not inlined are between 10% and 20% faster than PyPy 1.5. - faster warmup time for the JIT - JIT support for single floats (e.g., for ``array('f')``) - optimized dictionaries: the internal representation of dictionaries is now dynamically selected depending on the type of stored objects, resulting in faster code and smaller memory footprint. For example, dictionaries whose keys are all strings, or all integers. Other dictionaries are also smaller due to bugfixes. * JitViewer: this is the first official release which includes the JitViewer, a web-based tool which helps you to see which parts of your Python code have been compiled by the JIT, down until the assembler. The `jitviewer`_ 0.1 has already been release and works well with PyPy 1.6. * The CPython extension module API has been improved and now supports many more extensions. For information on which one are supported, please refer to our `compatibility wiki`_. * Multibyte encoding support: this was of of the last areas in which we were still behind CPython, but now we fully support them. * Preliminary support for NumPy: this release includes a preview of a very fast NumPy module integrated with the PyPy JIT. Unfortunately, this does not mean that you can expect to take an existing NumPy program and run it on PyPy, because the module is still unfinished and supports only some of the numpy API. However, barring some details, what works should be blazingly fast :-) * Bugfixes: since the 1.5 release we fixed 53 bugs in our `bug tracker`_, not counting the numerous bugs that were found and reported through other channels than the bug tracker. Cheers, Hakan Ardo, Carl Friedrich Bolz, Laura Creighton, Antonio Cuni, Maciej Fijalkowski, Amaury Forgeot d'Arc, Alex Gaynor, Armin Rigo and the PyPy team .. _`jitviewer`: http://morepypy.blogspot.com/2011/08/visualization-of-jitted-code.html .. _`bug tracker`: https://bugs.pypy.org .. _`compatibility wiki`: https://bitbucket.org/pypy/compatibility/wiki/Home

ANN: mock 0.8 beta 3
by Fuzzyman 18 Aug '11

18 Aug '11

I've released mock 0.8 beta 3. You can download it it or install it with: pip install -U mock==dev * http://www.voidspace.org.uk/python/mock * http://www.voidspace.org.uk/downloads/mock-0.8.0beta3.tar.gz mock is a library for testing in Python. It allows you to replace parts of your system under test with mock objects. The latest stable release is 0.7.2, which you can download from pypi. * http://pypi.python.org/pypi/mock mock 0.8 beta 3 is now feature complete, and is hopefully the code that will be released as mock 0.8 final. All that is left is documentation work, so now is the ideal time to try the beta! mock 0.8 is a big release with lots of improvements. You can read a summary of the new features in the following blog entries: * http://www.voidspace.org.uk/python/weblog/arch_d7_2011_08_13.shtml#e1224 * http://www.voidspace.org.uk/python/weblog/arch_d7_2011_07_30.shtml#e1223 * http://www.voidspace.org.uk/python/weblog/arch_d7_2011_07_16.shtml#e1220 * http://www.voidspace.org.uk/python/weblog/arch_d7_2011_06_11.shtml#e1219 The important new features in 0.8 include: * Addition of `mock_calls` list for *all* calls (including magic methods and chained calls) * `patch` and `patch.object` now create a `MagicMock` instead of a `Mock` by default * The patchers (`patch`, `patch.object` and `patch.dict`), plus `Mock` and `MagicMock`, take arbitrary keyword arguments for configuration * New mock assert methods `assert_any_call` and `assert_has_calls` * `patch.multiple` for doing multiple patches in a single call, using keyword arguments * Setting `side_effect` to an iterable will cause calls to the mock to return the next value from the iterable * New `new_callable` argument to `patch` and `patch.object` allowing you to pass in a class or callable object (instead of `MagicMock`) that will be called to replace the object being patched * Added `ANY` for ignoring arguments in `assert_called_with` calls * Addition of `call` helper object * Implemented auto-speccing (recursive, lazy speccing of mocks with mocked signatures for functions/methods), as the `autospec` argument to `patch` * Added the `create_autospec` function for manually creating 'auto- specced' mocks * Improved repr for mocks * Improved repr for `Mock.call_args` and entries in `Mock.call_args_list`, `Mock.method_calls` and `Mock.mock_calls` Other changes include: * New mock method `configure_mock` for setting attributes and return values / side effects on the mock and its attributes * Addition of `NonCallableMock` and `NonCallableMagicMock`, mocks without a `__call__` method * Addition of `mock_add_spec` method for adding (or changing) a spec on an existing mock * Protocol methods on `MagicMock` are magic mocks, and are created lazily on first lookup. This means the result of calling a protocol method is a MagicMock instead of a Mock as it was previously * In Python 2.6 or more recent, `dir` on a mock will report all the dynamically created attributes (or the full list of attributes if there is a spec) as well as all the mock methods and attributes. * Module level `FILTER_DIR` added to control whether `dir(mock)` filters private attributes. `True` by default. Note that `vars(Mock())` can still be used to get all instance attributes and `dir(type(Mock())` will still return all the other attributes (irrespective of `FILTER_DIR`) * `patch.TEST_PREFIX` for controlling how patchers recognise test methods when used to decorate a class * Support for using Java exceptions as a `side_effect` on Jython * `Mock` call lists (`call_args_list`, `method_calls` & `mock_calls`) are now custom list objects that allow membership tests for "sub lists" and have a nicer representation if you `str` or `print` them * Mocks attached as attributes or return values to other mocks have calls recorded in `method_calls` and `mock_calls` of the parent (unless a name is already set on the child) * Improved failure messages for `assert_called_with` and `assert_called_once_with` * Added the Mock API (`assert_called_with` etc) to functions created by `mocksignature` * Tuples as well as lists can be used to specify allowed methods for `spec` & `spec_set` arguments * Calling `stop` on an unstarted patcher fails with a more meaningful error message * BUGFIX: an error creating a patch, with nested patch decorators, won't leave patches in place * BUGFIX: `__truediv__` and `__rtruediv__` not available as magic methods on mocks in Python 3 * BUGFIX: `assert_called_with` / `assert_called_once_with` can be used with `self` as a keyword argument * BUGFIX: when patching a class with an explicit spec / spec_set (not a boolean) it applies "spec inheritance" to the return value of the created mock (the "instance") * BUGFIX: remove the `__unittest` marker causing traceback truncation Please try out the new beta and report any issues or give feedback on the new features. All the best, Michael Foord

Python 3.2.2rc1
by "Martin v. Löwis" 15 Aug '11

15 Aug '11

On behalf of the Python development team, I'm happy to announce the first release candidate of the Python 3.2.2 maintenance release (3.2.2rc1). Python 3.2.2 fixes `a regression <http://bugs.python.org/12576>`_ in the ``urllib.request`` module that prevented opening many HTTP resources correctly with Python 3.2.1. Python 3.2 is a continuation of the efforts to improve and stabilize the Python 3.x line. Since the final release of Python 2.7, the 2.x line will only receive bugfixes, and new features are developed for 3.x only. Since PEP 3003, the Moratorium on Language Changes, is in effect, there are no changes in Python's syntax and built-in types in Python 3.2. Development efforts concentrated on the standard library and support for porting code to Python 3. Highlights are: * numerous improvements to the unittest module * PEP 3147, support for .pyc repository directories * PEP 3149, support for version tagged dynamic libraries * PEP 3148, a new futures library for concurrent programming * PEP 384, a stable ABI for extension modules * PEP 391, dictionary-based logging configuration * an overhauled GIL implementation that reduces contention * an extended email package that handles bytes messages * a much improved ssl module with support for SSL contexts and certificate hostname matching * a sysconfig module to access configuration information * additions to the shutil module, among them archive file support * many enhancements to configparser, among them mapping protocol support * improvements to pdb, the Python debugger * countless fixes regarding bytes/string issues; among them full support for a bytes environment (filenames, environment variables) * many consistency and behavior fixes for numeric operations For a more extensive list of changes in 3.2, see http://docs.python.org/3.2/whatsnew/3.2.html To download Python 3.2 visit: http://www.python.org/download/releases/3.2/ Please consider trying Python 3.2 with your code and reporting any bugs you may notice to: http://bugs.python.org/ Enjoy! -- Martin v. Löwis (on behalf of the entire python-dev team and 3.2's contributors)
