First release of pyfsevents
by Nicolas Dumazet Sept. 3, 2009

Sept. 3, 2009

Hello! I am proud to announce the first release of pyfsevents, a C extension providing a Python interface to the FSEvents API. FSEvents is an Apple framework for Mac OS X >= 10.5 allowing monitoring of file system events on Mac OS platforms. * URL: http://pypi.python.org/pypi/pyfsevents * Mercurial repository: http://bitbucket.org/nicdumz/fsevents/ This extension was developed during a Google Summer of Code project [1] for Mercurial, to improve its inotify extension [2] As it is its first release I would welcome warmly any kind of feedback on that extension. Tests, code comments, feedback on the offered API, its documentation, distribution, etc... Anything, please let me know :) [1] http://socghop.appspot.com/student_project/show/google/gsoc2009/hg/t1240224… [2] http://mercurial.selenic.com/wiki/InotifyExtension -- Nicolas Dumazet — NicDumZ

ANN: PyBindGen 0.12 released
by Gustavo Carneiro Sept. 1, 2009

Sept. 1, 2009

PyBindGen is a Python module that is geared to generating C/C++ code that binds a C/C++ library for Python. It does so without extensive use of either C++ templates or C pre-processor macros. It has modular handling of C/C++ types, and can be easily extended with Python plugins. The generated code is almost as clean as what a human programmer would write. It can be downloaded from: http://code.google.com/p/pybindgen/ Bug reports should be filed here: https://bugs.launchpad.net/pybindgen === pybindgen 0.12 === - Now we can catch C++ exceptions and translate them into Python - New API to add container iteration powers to wrapped C++ classes - Unary minus operator support (J. Michael Owen) - CppMethod: is_pure_virtual=True should imply is_virtual=True - More polish for numeric operators with non-class right operand - Virtual methods regressions fixed - gccxmlparser: don't try to wrap private/protected operators - MSVC compilation fix - unsigned long type handlers (J. Michael Owen) - tp_len/__len__ works now with overloaded methods (J. Michael Owen) - Add foreign_cpp_namespace option to Function wrappers - Misc. cleanup and bug fixes -- Gustavo J. A. M.

[ANN] Pida 0.6beta3
by poelzi Sept. 1, 2009

Sept. 1, 2009

Pida is an IDE (integrated development environment). Pida is different from other IDEs in that it will use the tools you already have available rather than attempting to reinvent each one. Pida has unique features like a pluggable editor component supporting Vim, Emacs and Medit currently. We are proud to announce the hopefully last beta of Pida 0.6. [1] It was a long time since beta2 and a lot of changes happened since then: == Core Highlights == " multiprocessing language plugins Language plugins can now use a multiprocessing infrastructure which allows expensive operations to be done on other cpu cores. This increases the speed of plugins like python_lint and python dramatically and do not make the gui sluggish anymore. " project file caches Projects now have a filecache which allows fast queries to filenames and filetypes. The QuickOpen plugin provides a gui for this, allowing the user to open files to which parts of the name, path or filetype are known " very precise feature selection from LanguagePlugins " better filemonitor support " new documentation (needs some gui work tho) " lot of speedups " lot of usability enhancements " lots and lots of fixes == New Plugins == " RegexpToolkit - helps you develop and analyze regular expressions " QuickOpen - fast file opener for project files " WayPoint - autogenerates waypoints when you surf and edit files and allows to jump back and forth [1] http://pida.co.uk/blog/0.6beta3

CVE-2009-2701: Releases to fix ZODB ZEO server vulnerability
by Jim Fulton Sept. 1, 2009

Sept. 1, 2009

A vulnerability has been found in the Zope Object Database (ZODB) Zope Enterprise Objects (ZEO) server implementation that allows any file readable by the server to be read by clients and any file removable by the server to be removed. The vulnerability only applies if - you are using ZEO to share a database among multiple applications or application instances, - you allow untrused clients to connect to your ZEO server, and - the ZEO server is configured to support blobs. The vulnerability was introduced in ZODB 3.8. Overview -------- This vulnerability is addressed by updates to ZODB. A new release of ZODB is available here: http://pypi.python.org/pypi/ZODB3/3.8.3 (There is also a new development release at http://pypi.python.org/pypi/ZODB3/3.9.0c2.) If you are using blobs, we recommend updating any ZEO storage servers you're running to ZODB 3.8.3 (or ZODB 3.9.0c2). These versions support ZEO clients as old as ZODB 3.2. It isn't necessary to update client software (such as Zope application servers). Restricting access to ZEO storage servers ----------------------------------------- It is very important to restrict write access to ZODB databases. These releases only protect against vulnerabilities in the ZEO network protocol. ZODB uses Python pickles to store data. Loading data from the database can cause arbitrary code to be executed as part of object deserialization. Clients have full access to manipulate database data. For this reason, it is very important that only trusted clients be allowed to write to ZODB databases. Jim -- Jim Fulton
