Subprocess Crashes on OSX using wxpython GUI
by Shalin Shah Nov. 5, 2013

Nov. 5, 2013

Hello, I have a GUI software in which I wanted to do some heavy tasks so I create new subprocesses to run those tasks. To do this I am using multiprocessing module and this works perfectly fine on windows as well as unix. However when I try the same for OSX 10.6 process crash occurs and I get a long error report which I cannot decipher. Here is something I used to make a sub-process :- p = multiprocessing.Process(target = encode.encode , args = (self.path,self.savePath,) , name = "Encode … [View More]Process") p.start() temp = wx.ProgressDialog('Please wait...', 'Encoding the File....This may take several minutes....\n\t....so sit back and relax....',parent = self,style = wx.PD_APP_MODAL | wx.PD_CAN_ABORT) temp.SetSize((450,130))while len(multiprocessing.active_children()) != 0: time.sleep(0.1) if not temp.UpdatePulse("Encoding the File....This may take several minutes...\n\tso sit back and relax.....")[0]: p.terminate() terminated = True break temp.Destroy() p.join() p.terminate() Here is the crash report :- Path:/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/PythonIdentifier: PythonVersion: ???

python2.7/subprocess.py Popen on Ubuntu 10.04 Bug
by Eyal Moscovici Nov. 4, 2013

Nov. 4, 2013

Hi, I found that using Popen with both executable and shell parameters set creates a bug: For example: Calling: Popen(["-a"], exacutable="/bin/ls", shell=True) Exacutes: /bin/ls -c -a instead of: /bin/sh -c "/bin/ls -a" The bug in the function: def _execute_child(self, args, executable, preexec_fn, close_fds, cwd, env, universal_newlines, startupinfo, creationflags, shell, p2cread, p2cwrite, … [View More]

pygettext is obsolete
by Tom Wallroth Nov. 4, 2013

Nov. 4, 2013

Dear mailing list, The documentation for i18n support is a bit outdated. It mentions pygettext, but it seems that pygettext was declared obsolete by just about anybody in 2004 and was replaced by its original implementation "xgettext". Here's a link to the part of the documentation, which is outdated: http://docs.python.org/3.3/library/gettext.html#id3 And some proof of pygettext not being used anymore since 2004: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=246332 Sincerely, Tom Wallroth

[issue17827] Document codecs.encode and codecs.decode

New submission from Nick Coghlan: The codecs module has long offered encode() and decode() convenience functions (since 2004: http://hg.python.org/cpython-fullhistory/rev/8ea2cb1ec598), but they're not documented (except through docstrings). We should fix that. >From the docstrings: ========== encode(obj, [encoding[,errors]]) -> object Encodes obj using the codec registered for encoding. encoding defaults to the default encoding. errors may be given to set a different error handling … [View More]

Nov. 3, 2013

New submission from Zachary Ware: As discussed in issue19273, here are a pair of patches that correct factual errors in PCbuild/readme.txt in both 2.7 and 3.3. The 3.3 patch makes the following changes: - Remove Win2k mentions, it is not supported (Tcl nmake command also adjusted) - MSVCRT9 -> MSVCRT10 - SQLite 3.7.4 -> 3.7.12, remove "(see below)" with nothing to see - .vcproj -> .vcxproj, all occurrences - _bz2.vcxproj isn't as magical as it was made out to be, and it can clean … [View More]
