stevedore 0.15
by Doug Hellmann 27 Mar '14

27 Mar '14

stevedore 0.15 What is stevedore? Python makes loading code dynamically easy, allowing you to configure and extend your application by discovering and loading extensions (plugins) at runtime. Many applications implement their own library for doing this, using __import__ or importlib. [1]stevedore avoids creating yet another extension mechanism by building on top of [2]setuptools entry points. The code for managing entry points tends to be repetitive, though, so stevedore provides manager classes for implementing common patterns for using dynamically loaded extensions. What's New? * Only log errors from loading plugins if no error handler callback is provided. Installing Visit the [3]stevedore project page for download links and installation instructions.

PyDev 3.4.1 Released
by Fabio Zadrozny 20 Mar '14

20 Mar '14

What is PyDev? --------------------------- PyDev is an open-source Python IDE on top of Eclipse for Python, Jython and IronPython development. It comes with goodies such as code completion, syntax highlighting, syntax analysis, code analysis, refactor, debug, interactive console, etc. Details on PyDev: http://pydev.org Details on its development: http://pydev.blogspot.com What is LiClipse? --------------------------- LiClipse is a PyDev standalone with goodies such as support for Multiple cursors, theming and a number of other languages such as Django Templates, Kivy Language, Mako Templates, Html, Javascript, etc. It's also a commercial counterpart which helps supporting the development of PyDev. Details on LiClipse: http://brainwy.github.io/liclipse/ Release Highlights: ------------------------------- - **Important**: PyDev requires Eclipse 3.8 or 4.3 onwards and Java 7! For older versions, keep using PyDev 2.x (or LiClipse for a PyDev standalone with all requirements bundled). - **Interactive Console**: * **Send a single line to the interactive console with F2** (akin to Ctrl+Alt+Enter but only for the current line). - **Debugger**: * **Added support for debugging spawned subprocesses.** * New Django launches no longer have -noreload to take advantage of that (but existing launches have to be manually edited -- or removed and recreated). * When terminating a process its subprocesses are also killed (avoiding django zombie processes). * In the debugger, locals are now also properly saved on PyPy (requires a newer version of PyPy too). * Remote Debugger: when specifying items in PATHS_FROM_ECLIPSE_TO_PYTHON pathnames are normalized. * Fixes to work with Jython 2.1 and Jython 2.2.1 * Always setting PYTHONUNBUFFERED environment variable to 1. * The python default encoding is no longer changed (only PYTHONIOENCODING is used now and not sys.setdefaultencoding). * Minor improvements on get referrers. - **General**: * **Cython: .pxd and .pxi files are properly supported.** * Interpreter configuration: It's possible to reorder PYTHONPATH entries with drag and drop. * Fixed django interactive shell to work with newer versions of Django. * Rename working properly for files without extensions. * Fixed issue where specifying the type of a variable with a comment was not detected in the code-completion. * Fixed issue where we'd open a file as if it was an external file when it was actually a file in the workspace or inside a source folder. * PyDev Package Explorer: fixed issue where some errors would remain showing when they didn't exist anymore. * PyDev Package Explorer: fixed issue where items could change its order depending on decorations. * On a double-click on spaces, all the spaces are selected. - **Test Runner**: * **Improved py.test integration**: it's now possible to select which tests to run with Ctrl+F9 (even if not under a class). * No longer breaks if a file which was in a launch config is removed (still runs other tests in the launch). * After a test run finishes, if there are non-daemon threads running they're printed to the output. * Fixed UnicodeDecodeError when running unit-tests under python 2.x * Fixed issue on test discovery on Linux. - **Sorting Imports**: * Sort of imports no longer adds spaces at end of imports. * Sort of imports no longer passes the number of available columns specified. * It's now also possible to keep the names of 'from' imports sorted. Cheers, -- Fabio Zadrozny ------------------------------------------------------ Software Developer LiClipse http://brainwy.github.io/liclipse PyDev - Python Development Environment for Eclipse http://pydev.org http://pydev.blogspot.com

[ANN]: distlib 0.1.8 released on PyPI
by Vinay Sajip 19 Mar '14

19 Mar '14

I've released version 0.1.8 of distlib on PyPI [1]. For newcomers, distlib is a library of packaging functionality which is intended to be usable as the basis for third-party packaging tools. The main changes in this release are as follows: * Fixed issue #45: Improved thread-safety in SimpleScrapingLocator. * Fixed issue #42: Handling of pre-release legacy version numbers now mirrors setuptools logic. * Added exists, verify, update, is_compatible and is_mountable methods to the Wheel class (the update method fixed issue #41). * Added a search method to the PackageIndex class. * Fixed a bug in the Metadata.add_requirements method. * Allowed versions with a single numeric component and a local version component (tracking changes to PEP 440).* Corrected spelling of environment variable used for the stub launcher on OS X. * Avoided using pydist.json in 1.0 wheels (bdist_wheel writes a non- conforming pydist.json). * Improved computation of ABI tags on Python versions where SOABI is not available, and improved computation of compatibility tags on OS X to allow for multiple architectures and older OS X versions. A more detailed change log is available at [2]. Please try it out, and if you find any problems or have any suggestions for improvements, please give some feedback using the issue tracker! [3] Regards, Vinay Sajip [1] https://pypi.python.org/pypi/distlib/0.1.8 [2] http://pythonhosted.org/distlib/overview.html#change-log-for-distlib [3] https://bitbucket.org/pypa/distlib/issues/new

mimedecode.py version 2.5.0
by Oleg Broytman 17 Mar '14

17 Mar '14

Hello! mimedecode.py WHAT IS IT Mail users, especially in non-English countries, often find that mail messages arrived in different formats, with different content types, in different encodings and charsets. Usually this is good because it allows us to use appropriate format/encoding/whatever. Sometimes, though, some unification is desirable. For example, one may want to put mail messages into an archive, make HTML indices, run search indexer, etc. In such situations converting messages to text in one character set and skipping some binary attachments is much desirable. Here is the solution - mimedecode.py. This is a program to decode MIME messages. The program expects one input file (either on command line or on stdin) which is treated as an RFC822 message, and decodes to stdout or an output file. If the file is not an RFC822 message it is just copied to the output one-to-one. If the file is a simple RFC822 message it is decoded as one part. If it is a MIME message with multiple parts ("attachments") all parts are decoded. Decoding can be controlled by command-line options. WHAT'S NEW in version 2.5.0 (2014-03-18) Add option --set-header=header:value to set header's value (only at the top level). Add option --set-param=header:param=value to set header parameter's value (only at the top level). The header must exist. Add option -B to skip content-transfer-decoding binary attachments. Add options --save-headers, --save-body and --save-message to save decoded headers/bodies/messages to files. Add option -O to set the destination directory for output files. Fix a minor bug: if a multipart message (or a subpart) lacks any textual content - avoid putting an excessive newline. WHERE TO GET Home page: http://phdru.name/Software/Python/#mimedecode git clone http://git.phdru.name/mimedecode.git git clone git://git.phdru.name/mimedecode.git Requires: Python 2.2.2+, m_lib 2.0+. Recommends: configured mailcap database. Documentation: http://phdru.name/Software/Python/mimedecode.html (also included in the package in html, man and txt formats).

Crochet 1.1.0 - Use Twisted anywhere!
by Itamar Turner-Trauring 15 Mar '14

15 Mar '14

Crochet is an MIT-licensed library that makes it easier for blocking or threaded applications like Flask or Django to use the Twisted networking framework. Crochet provides the following features: * Runs Twisted's reactor in a thread it manages. * The reactor shuts down automatically when the process' main thread finishes. * Hooks up Twisted's log system to the Python standard library logging framework. Unlike Twisted's built-in logging bridge, this includes support for blocking Handler instances. * A blocking API to eventual results (i.e. Deferred instances). This last feature can be used separately, so Crochet is also useful for normal Twisted applications that use threads. Downloads: https://pypi.python.org/pypi/crochet Documentation: https://crochet.readthedocs.org/en/latest/ *Trivial Example * """ Download a web page in a blocking manner. """ from __future__ import print_function import sys from twisted.web.client import getPage from crochet import setup, wait_for_reactor setup() @wait_for_reactor def download_page(url): return getPage(url) # download_page() now behaves like a normal blocking function: print(download_page(sys.argv[1])) *What's New in 1.1.0* Bug fixes: * EventualResult.wait() can now be used safely from multiple threads, thanks to Gavin Panella for reporting the bug. * Fixed reentrancy deadlock in the logging code caused by http://bugs.python.org/issue14976, thanks to Rod Morehead for reporting the bug. * Crochet now installs on Python 3.3 again, thanks to Ben Cordero. * Crochet should now work on Windows, thanks to Konstantinos Koukopoulos. * Crochet tests can now run without adding its absolute path to PYTHONPATH or installing it first. Documentation: * EventualResult.original_failure is now documented. **
