(Patch by Roger Serwy) The double negative here makes this impossible to understand. Could we please get an updated NEWS entry that explains what actually changed in IDLE to fix this? Perhaps something like "IDLE now always sets the default keybind for Return correctly, ensuring commands can be executed in the IDLE shell window"? (assuming that's what happened). This is important, folks: NEWS entries need to be comprehensible for people that *haven't* read the associated tracker issue. This means that issue titles (which generally describe a problem someone was having) are often inappropriate as NEWS items. NEWS items should be short descriptions that clearly describe *what changed*, perhaps with some additional information to explain a bit about why the change was made.

Bug in generator if the generator in created in a C thread
by Victor Stinner March 30, 2012

March 30, 2012

Hi, bugs.python.org is down so I'm reporting the bug here :-) We have a crash in our product when tracing is enabled by sys.settrace() and threading.settrace(). If a Python generator is created in a C thread, calling the generator later in another thread may crash if Python tracing is enabled. - the C thread calls PyGILState_Ensure() which creates a temporary Python thread state - a generator is created, the generator has a reference to a Python frame which keeps a reference to the temporary Python thread state - the C thread calls PyGILState_Releases() which destroys the temporary Python thread state - when the generator is called later in another thread, call_trace() reads the Python thread state from the generator frame, which is the destroyed frame => it does crash on a pointer dereference if the memory was reallocated (by malloc()) and the data were erased To reproduce the crash, unpack the attached generator_frame_bug.tar.gz, compile the C module using "python setup.py build" and then run "PYTHONPATH=$(ls -d build/lib*/) python test.py" (or just "python test.py if you installed the _test module). You may need to use Valgrind to see the error, or call memset(tstate, 0xFF, sizeof(*tstate)) before free(tstate) in tstate_delete_common(). Calling the generator should update its reference to the Python state thread in its frame. The generator may also clears frame->f_tstate (to detect bugs earlier), as it does for frame->f_back (to avoid a reference cycle). Attached patch implements this fix for Python 3.3. Victor

Integrating the PEP 397 launcher
by Brian Curtin March 30, 2012

March 30, 2012

After talking with Martin and several others during the language summit and elsewhere around PyCon, PEP 397 should be accepted. I don't remember who, but some suggested it should just be a regular old feature instead of going through the PEP process. So...does this even need to continue the PEP process? Vinay - is the code you have on bitbucket ready to roll into CPython, thus into the installer?

The NEWS entries need to be treated as being at least close to on par with the rest of the docs - it's OK if someone can't come up with the words themselves, but if that's the case, then it's preferable to ask for help with the wording explicitly. Is my suggested rephrasing correct? I don't know, as I'm not familiar with either the original problem or what was done to fix it.

Virtualenv not portable from Python 2.7.2 to 2.7.3 (os.urandom missing)
by Jason R. Coombs March 30, 2012

March 30, 2012

I see this was reported as a debian bug. http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=665776 We encountered it as well. To reproduce, using virtualenv 1.7+ on Python 2.7.2 on Ubuntu, create a virtualenv. Move that virtualenv to a host with Python 2.7.3RC2 yields: jaraco@vdm-dev:~$ /usr/bin/python2.7 -V Python 2.7.3rc2 jaraco@vdm-dev:~$ env/bin/python -V Python 2.7.2 jaraco@vdm-dev:~$ env/bin/python -c "import os; os.urandom()" Traceback (most recent call last): File "<string>", line 1, in <module> AttributeError: 'module' object has no attribute 'urandom' This bug causes Django to not start properly (under some circumstances). I reviewed the changes between v2.7.2 and 2.7 (tip) and it seems there was substantial refactoring of the os and posix modules for urandom. I still don't fully understand why the urandom method is missing (because the env includes the python 2.7.2 executable and stdlib). I suspect this change is going to cause some significant backward compatibility issues. Is there a recommended workaround? Should I file a bug? Regards, Jason

possible distutils.sysconfig.get_config_var bug
by Jordan Schneider March 29, 2012

March 29, 2012

Hi python-dev, Sorry if this is the wrong place to discuss this potential bug - feel free to point me in the right direction if so. I'm running OS X 10.7.3, and have two python2.7s installed, one system default in /usr/bin and the other by homebrew symlinked in /usr/local/bin. While running a configure script, distutils.sysconfig.get_config_var is not returing a full path for my homebrew Python framework, like so: Python 2.7.2 (default, Mar 28 2012, 02:31:16) [GCC 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.1.00)] on darwin >>> distutils.sysconfig.get_config_var('LINKFORSHARED') '-u _PyMac_Error Python.framework/Versions/2.7/Python' (the full path should be /usr/local/Cellar/python/2.7.2/Frameworks/Python.framework/Versions/2.7/Python) Whereas from the system python in /usr/bin: Python 2.7.1 (r271:86832, Jul 31 2011, 19:30:53) [GCC 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2335.15.00)] on darwin >>> distutils.sysconfig.get_config_var('LINKFORSHARED') '-u _PyMac_Error /System/Library/Frameworks/Python.framework/Versions/2.7/Python' This seems like a bug, no? Thanks for the help, Jordan

Bug tracker outage
by "Martin v. Löwis" March 29, 2012

March 29, 2012

Upfront hosting (Izak Burger) is going to do a Debian upgrade of the bug tracker machine "soon" (likely tomorrow). This may cause some outage, since there is a lot of custom stuff on the machine which may break with newer (Python) versions. I'll notify here when the upgrade is complete. Regards, Martin
