[RELEASED] Python 2.6.8, 2.7.3, 3.1.5, and 3.2.3
by Benjamin Peterson April 11, 2012

April 11, 2012

We're bursting with enthusiasm to announce the immediate availability of Python 2.6.8, 2.7.3, 3.1.5, and 3.2.3. These releases included several security fixes. Note: Virtualenvs created with older releases in the 2.6, 2.7, 3.1, or 3.2 series may not work with these bugfix releases. Specifically, the os module may not appear to have a urandom function. This is a virtualenv bug, which can be solved by recreating the broken virtualenvs with the newer Python versions. The main impetus for these releases is fixing a security issue in Python's hash based types, dict and set, as described below. Python 2.7.3 and 3.2.3 include the security patch and the normal set of bug fixes. Since Python 2.6 and 3.1 are maintained only for security issues, 2.6.8 and 3.1.5 contain only various security patches. The security issue exploits Python's dict and set implementations. Carefully crafted input can lead to extremely long computation times and denials of service. [1] Python dict and set types use hash tables to provide amortized constant time operations. Hash tables require a well-distributed hash function to spread data evenly across the hash table. The security issue is that an attacker could compute thousands of keys with colliding hashes; this causes quadratic algorithmic complexity when the hash table is constructed. To alleviate the problem, the new releases add randomization to the hashing of Python's string types (bytes/str in Python 3 and str/unicode in Python 2), datetime.date, and datetime.datetime. This prevents an attacker from computing colliding keys of these types without access to the Python process. Hash randomization causes the iteration order of dicts and sets to be unpredictable and differ across Python runs. Python has never guaranteed iteration order of keys in a dict or set, and applications are advised to never rely on it. Historically, dict iteration order has not changed very often across releases and has always remained consistent between successive executions of Python. Thus, some existing applications may be relying on dict or set ordering. Because of this and the fact that many Python applications which don't accept untrusted input are not vulnerable to this attack, in all stable Python releases mentioned here, HASH RANDOMIZATION IS DISABLED BY DEFAULT. There are two ways to enable it. The -R commandline option can be passed to the python executable. It can also be enabled by setting an environmental variable PYTHONHASHSEED to "random". (Other values are accepted, too; pass -h to python for complete description.) More details about the issue and the patch can be found in the oCERT advisory [1] and the Python bug tracker [2]. Another related security issue fixed in these releases is in the expat XML parsing library. expat had the same hash security issue detailed above as Python's core types. The hashing algorithm used in the expat library is now randomized. A few other security issues were fixed. They are described on the release pages below. These releases are production releases.

PyDev 2.5.0 Released
by Fabio Zadrozny April 6, 2012

April 6, 2012

Hi All, PyDev 2.5.0 has been released Details on PyDev: http://pydev.org Details on its development: http://pydev.blogspot.com Release Highlights: ------------------------------- Django: Project wizard now properly supports Django 1.4. Django with auto-reload: pydevd.patch_django_auto_reload() now properly patches Django 1.4 for the remote debugger. pydevd.patch_django_auto_reload() now patches the Django reload to show a console out of Eclipse so that Ctrl+C can be used. Created code template to pydevd.patch_django_auto_reload(). Interactive Console: The interactive console may be attached to the variables view (patch from Jonah Graham). See: http://pydev.org/manual_adv_interactive_console.html for details. Drag and Drop may be used to drag code from the editor to the interactive console (patch from Jonah Graham). When starting an interactive console, a link to configure the preferences is shown in the dialog. Code formatter: Multi-lines may be right-trimmed (patch from Haw-Bin Chai) -- option must be enabled in the code-formatting settings. Fixed issue where the auto code-formatting would end up formatting strings as regular code when the "format only changed lines" setting was on. Others: pydevd.settrace() template now adds the debugger to the PYTHONPATH before actually doing the settrace(). ${pydevd_file_location} and ${pydevd_dir_location} variables were added to the templates. The style of generated docstrings (EpyDoc or Sphinx) may be chosen in the preferences (patch from Paul Collins). Some performance improvements were done on the parser. Aside from the features above, lots of bugs were fixed in this release (including a deadlock in a race condition). 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

New release of CodeInvestigator
by hans moleman April 3, 2012

April 3, 2012

CodeInvestigator version 2.0.0 was released on April 2. Bug fixes: - Unicode printing - old runs were not always removed - Unicode searches - 'if condition: continue' on one line, failed - print '' failed Changes: - Google app engine - debug data remains visible in another iteration - going back to previous code via History now faster - more feedback when selecting another iteration - font consistency 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
