Python 3. OS/X 10.6 Ipython
by John Riordan April 9, 2011

April 9, 2011

I am trying to get IPython running with Python 3.1 on OS/X 10.6.3. The install script for IPython configures it to run with Python 2.6. Is there a way around this?

MySQLdb on OS X 10.6
by Brian Zambrano Oct. 31, 2010

Oct. 31, 2010

Hi all, Like many others before me, I'm banging my head against the wall trying to get MySQLdb working on my new MacBook Pro with Snow Leopard. I have MySql 5.1 x86_64 installed, configured and running. I'm building MySQLdb 1.2.3c1 like this: export ARCHFLAGS='-arch x86_64' python setup.py build python setup.py install But it simply doesn't work....and apparently I'm not the only one<http://bit.ly/3iQy2> : (eb)brianz@eb-brianz$ python -c "import MySQLdb" Traceback (most recent call last): File "<string>", line 1, in <module> File "MySQLdb/__init__.py", line 19, in <module> import _mysql ImportError: dlopen(./_mysql.so, 2): no suitable image found. Did find: ./_mysql.so: mach-o, but wrong architecture Everything *looks* ok: (eb)brianz@eb-brianz$ file _mysql.so _mysql.so: Mach-O 64-bit bundle x86_64 (eb)brianz@eb-brianz$ otool -L _mysql.so _mysql.so: /usr/local/mysql/lib/libmysqlclient_r.16.dylib (compatibility version 17.0.0, current version 17.0.0) /usr/lib/libz.1.dylib (compatibility version 1.0.0, current version 1.2.3) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 124.1.1) (eb)brianz@eb-brianz$ (eb)brianz@eb-brianz$ file /usr/local/mysql/lib/libmysqlclient_r.16.dylib /usr/local/mysql/lib/libmysqlclient_r.16.dylib: Mach-O 64-bit dynamically linked shared library x86_64 Huh? Something is not right here. It sucks that the OS X builds are so painful. I'm sort of at a loss at where to go next. Suggestions? Any help greatly appreciated!

Weird Carbon: gestalt: wxPython issue/bug
by Christopher Barker Oct. 13, 2010

Oct. 13, 2010

Hi folks, Peter Hanson, on the wxPython list, seems to have identified a bug in the gestalt module, that may be a Carbon issue. It's a bit of an unusual case: it freezes up wxPython, when wx is called from other than the main thread. Robin Dunn suspects that it's a Carbon issue -- gestalt is calling Carbon, and doing so in the main thread, so you are then trying to call Carbon from more than one thread, which may be the cause of the problem. I've confirmed that if you call gestalt from the same thread as wxPython, there is no failure. A link to Robin Dunn's assessment: http://permalink.gmane.org/gmane.comp.python.wxpython/76590 As Carbon is deprecated anyway, I guess it's time for gestalt ( or platform.mac_ver ) to be re-written I've tested on OS-X 10.4.11, Python 2.5 and Python2.6 Here is Peter's summary and sample code: # Demonstration of application freeze on OSX. # Running "python osx_freeze.py" shows the symptom: # non-responsiveness after about 3 seconds. In theory # this will occur in any wxPython app which runs # the GUI event loop in a thread other than the one # in which the failing gestalt('sysu') call (see below) # is first executed. # Enabling any of these imports can trigger the problem # as each one imports the next one down in the list. # This will happen only with pkg_resources v0.6c10 or later # although it's not pkg_resources' fault. # import matplotlib.figure # import matplotlib.axes # import matplotlib.dates # import pytz # import pkg_resources # The next import alone doesn't lead to failure, # but the function call does. # This same code is executed by pkg_resources starting # with setuptools v0.6c10. # from platform import mac_ver; mac_ver() # The platform.mac_ver() call does the following, which # is what ultimately leads to the failure. Calls # to gestalt() with 'sysa' (for example) do not # trigger the problem, either because the problem is # related to the 'sysu' itself, or to the fact that # an exception is raised because the selector "sysu" # is no longer recognized. from gestalt import gestalt try: print gestalt('sysu') except Exception, ex: print 'gestalt call failed' if __name__ == '__main__': def gui(): import wx app = wx.App(False) frame = wx.Frame(None) wx.StaticText(frame, label='Goodbye, cruel world') frame.Show() app.MainLoop() import threading threading.Thread(target=gui).start() -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception Chris.Barker(a)noaa.gov

XCode for OS X 10.5?
by Skip Montanaro June 26, 2010

June 26, 2010

Sorry to ask a non-Python question here, but I need this to get my laptop rebuilt so I can do stuff again. I lost the disk on my Macbook Pro which Apple kindly replaced, however my backups were partially toast, so I had to reinstall OS X from scratch. (Luckily /Users was viable. Whew!) I can't find a version of XCode which works with Mac OS X 10.5. All Apple will show me on their dev site is XCode 3.2 which requires Snow Leopard. I can't build a dang thing - no make or gcc for instance. Any pointers appreciated. Thanks, Skip Montanaro

get an OS X buildbot into the "stable" set
by Bill Janssen June 23, 2010

June 23, 2010

I just noticed that the list of "stable" Python buildbots don't include any OS X buildbots. From the web page, the definition of "stable" is this: ``The stable versions are the primary platforms that should always have all tests passing.'' Don't we want OS X in that set of platforms? Bill

You'll get a much more readable error message from CommandError.__str__(). Digging through it, the error number is -1720, 'invalid range'. I'm not familiar with Skim, but a quick test confirms the same commands produce the same error in AppleScript too: tell application "Skim" set r to item 1 of (get selection of note 1 of document 1) get contents of r end tell -- error "Skim got an error: Invalid range." number -1720 from characters 222 thru 286 of text of page 4 of document "points-of-view.pdf" So I would suggest taking it up with the Skim authors, as it's probably a bug in their scripting support.

py2app applet: cannot drag files onto dock icon
by Russell E. Owen June 18, 2010

June 18, 2010

I am making a Mac drag-and-drop applet using py2app. The resulting application runs, and I can drag files onto the application's icon in Finder, but I cannot drag files onto the application's icon in the Dock. The application processes plain text files. The property list is as follows (I reluctantly decided not to list allowed file suffixes because the appropriate keyword is deprecated for 10.5): plist = dict( CFBundleName = appName, CFBundleExecutable = appName, CFBundleShortVersionString = versStr, CFBundleGetInfoString = "%s %s" % (appName, versStr), CFBundleDocumentTypes = [ dict( CFBundleTypeName = "TEXT", CFBundleTypeRole = "Viewer", LSItemContentTypes = [ "public.plain-text", "public.text", "public.data", ], ), ], ) and when I look at the final info.plist and compare it to the plist from other applications I don't see anything glaringly different (but I'm not an expert on application proper lists). Any idea what's going on? It's a serious limitation not to be able to drag file onto the dock icon. -- Russell

Help with py-appscript?
by Charles Turner June 17, 2010

June 17, 2010

Hi all- Although I'm sure I qualify as a Python noobie as well as with Applescript and Skim, I've run into the following and hope someone could shed some light for me. I have the following script: from appscript import * skim = app('Skim.app') reference = skim.documents[1].notes[1].selection.get()[0] print reference which produces the reference: app(u'/Applications/Skim.app').documents[u'blair-2004.pdf'].pages[1].text.characters[app.documents[u'blair-2004.pdf'].pages[1].text.characters[1022]:app.documents[u'blair-2004.pdf'].pages[1].text.characters[1147]] If I change the last line of the script to: print reference.get() it generates: CommandError: app(u'/Applications/Skim.app').documents[u'blair-2004.pdf'].pages[1].text.characters[app.documents[u'blair-2004.pdf'].pages[1].text.characters[1022]:app.documents[u'blair-2004.pdf'].pages[1].text.characters[1147]].get, ((), {}), aem.EventError(-1720, '', {'errn': <aem.ae.AEDesc type='long' size=4>, 'erob': <aem.ae.AEDesc type='obj ' size=932>}) function __call__ in untitled at line 499 raise CommandError(self, (args, kargs), e, self.AS_appdata) Can someone point out what I'm doing wrong here? Thanks in advance, Charles
