appscript and launching apps from "background-only" Python processes
by Bill Janssen Oct. 29, 2008

Oct. 29, 2008

I'm starting a Python daemon using SystemStarter, and in it I'm using appscript to launch an app (Entourage). I get the following error: CantLaunchApplicationError: CantLaunchApplicationError -606: Application is background-only. If I start the same daemon from the command-line manually, it works fine. I'm guessing that some environment variable is not being set by SystemStarter, which is what makes it "background-only". Can anyone shed some light on this? Bill

Python 2.6 / appscript 0.18.1 DeprecationWarnings fix
by Florian Höch Oct. 28, 2008

Oct. 28, 2008

Hello list, I hope this is the correct place to send patches to :) I noticed that appscript generates some DeprecationWarnings when used with Python 2.6. It is easily fixed though (I've copied the fixup code verbatim from Python 2.6's ConfigParser.py): --- appscript-0.18.1/Lib/aem/send.py.bak Tue Nov 20 19:57:38 2007 +++ appscript-0.18.1/Lib/aem/send.py Sun Oct 26 19:09:37 2008 @@ -132,6 +132,21 @@ raw : AppleEvent | None -- raw reply event, in case alternate/additional processing of error info is required, or None if error occurred while outgoing event was being sent """ + def _get_message(self): + """Getter for 'message'; needed only to override deprecation in + BaseException.""" + return self.__message + + def _set_message(self, value): + """Setter for 'message'; needed only to override deprecation in + BaseException.""" + self.__message = value + + # BaseException.message has been deprecated since Python 2.6.

py2app and dependencies
by Ryan Govostes Oct. 27, 2008

Oct. 27, 2008

I'm having some trouble with py2app messing up package dependencies. I built py2app from SVN HEAD a few days ago because the version distributed with Apple's Python 2.5 did not appear to support egg dependencies. 1. It is failing to find the text_format module of Google's protobuf package, despite the fact that it is explicitly imported from google.protobuf.message: > from google.protobuf import text_format 2. Another package is not explicitly imported, so I think I have to specify it as a dependency. However, if I add it to the "packages" list, I get an error > ImportError: No module named xyzzy > > /Users/ryan/trunk/build/bdist.macosx-10.5-i386/egg/modulegraph/ > util.py(13)imp_find_module() This is despite the fact that I can import the package with Python interactively. It also fails if I try making a recipe. Is there a way to tell py2app what to include explicitly in these cases? Or should I do some post-build surgery on the resultant .app? Regards, Ryan Govostes

IDE that doesn't look awful?
by Joe Strout Oct. 27, 2008

Oct. 27, 2008

Hi all, I'd heard good things about Wing IDE (including that it was written with wxPython, and I know that wxPython can make decent Mac apps with a bit of care). So I downloaded the disk image today, and man -- is it ever ugly! It's really not a Mac app at all, but an X-Window app, with all the usual cruft that brings. Even XCode is better than that. I know I shouldn't care, but... somehow, I do. Is there any Python IDE that looks and feels more like a proper Mac app? Thanks, - Joe

Py2App and PyQT

Hello, Now that I have my application running and packaged on Windows and Linux, I'm trying to get it working under Mac Os X ( Leopard 10.5.5 ). Everything seem to be fine on compilation side, but when I launch my application I'm getting : Traceback (most recent call last): File "/Volumes/sIBL/src/dist/sIBL_GUI.app/Contents/Resources/__boot__.py", line 137, in <module> _run('sIBL_GUI.py') File "/Volumes/sIBL/src/dist/sIBL_GUI.app/Contents/Resources/__boot__.py", line 134, in _run execfile(path, globals(), globals()) File "/Volumes/sIBL/src/dist/sIBL_GUI.app/Contents/Resources/sIBL_GUI.py", line 71, in <module> from PyQt4.QtCore import * File "PyQt4/QtCore.pyc", line 18, in <module> File "PyQt4/QtCore.pyc", line 15, in __load ImportError: '/System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/lib-dynload/PyQt4/QtCore.so' not found 2008-10-26 08:55:36.106 sIBL_GUI[432:10b] sIBL_GUI Error 2008-10-26 08:55:36.117 sIBL_GUI[432:10b] sIBL_GUI Error An unexpected error has occurred during execution of the main script ImportError: '/System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/lib-dynload/PyQt4/QtCore.so' not found This is pretty strange because I actually found that the file is correctly included in "dist/sIBL_GUI.app/Contents/Resources/lib/python2.5/lib-dynload/PyQt4/" directory. Anyone faced this or have an idea ? Thanks, Thomas

I'm using the /usr/bin/python, consistently. If a non-GUI process launched from an .app bundle calls certain OS APIs, OS X automatically upgrades it to full GUI status. e.g. Py- appscript has this problem, despite having no need for a Window Manager connection itself: it calls Process Manager, which is one of the APIs in question, and the python interpreter is packaged as an .app, so you get a bouncing Dock icon any time you use appscript from the command line. By comparison, Ruby's interpreter isn't packaged as an .app, so using rb-appscript won't automatically GUI-fy your ruby process.

python 2.6 on mac seems to break compatibility
by Rodrigo Ventura Oct. 25, 2008

Oct. 25, 2008

I'm having difficulty on compiling PIL on Leopard. PIL used to compile just fine with the system's python (2.5.1 I believe), but with macpython 2.6 it breaks. First of all, I get lots of warnings after almost all gcc calls during compilation that I did't get before. Sample example: gcc -arch ppc -arch i386 -isysroot /Developer/SDKs/MacOSX10.4u.sdk - fno-strict-aliasing -fno-common -dynamic -DNDEBUG -g -O3 - DHAVE_LIBJPEG -DHAVE_LIBZ -I/System/Library/Frameworks/Tcl.framework/ Headers -I/System/Library/Frameworks/Tk.framework/Headers -I/opt/local/ include/freetype2 -IlibImaging -I/opt/local/include -I/Library/ Frameworks/Python.framework/Versions/2.6/include -I/usr/include -I/ Library/Frameworks/Python.framework/Versions/2.6/include/python2.6 -c libImaging/RawDecode.c -o build/temp.macosx-10.3-i386-2.6/libImaging/ RawDecode.o In file included from /usr/include/math.h:26, from /Library/Frameworks/Python.framework/Versions/ 2.6/include/python2.6/pyport.h:235, from /Library/Frameworks/Python.framework/Versions/ 2.6/include/python2.6/Python.h:58, from libImaging/ImPlatform.h:10, from libImaging/Imaging.h:14, from libImaging/RawDecode.c:17: /usr/include/architecture/ppc/math.h:675: warning: conflicting types for built-in function 'scalb' Another illustrative example: gcc -arch ppc -arch i386 -isysroot /Developer/SDKs/MacOSX10.4u.sdk - fno-strict-aliasing -fno-common -dynamic -DNDEBUG -g -O3 -I/System/ Library/Frameworks/Tcl.framework/Headers -I/System/Library/Frameworks/ Tk.framework/Headers -I/opt/local/include/freetype2 -IlibImaging -I/ opt/local/include -I/Library/Frameworks/Python.framework/Versions/2.6/ include -I/usr/include -I/Library/Frameworks/Python.framework/Versions/ 2.6/include/python2.6 -c Tk/tkImaging.c -o build/temp.macosx-10.3- i386-2.6/Tk/tkImaging.o -framework Tcl -framework Tk In file included from /usr/include/math.h:26, from /Library/Frameworks/Python.framework/Versions/ 2.6/include/python2.6/pyport.h:235, from /Library/Frameworks/Python.framework/Versions/ 2.6/include/python2.6/Python.h:58, from libImaging/ImPlatform.h:10, from libImaging/Imaging.h:14, from Tk/tkImaging.c:53: /usr/include/architecture/ppc/math.h:675: warning: conflicting types for built-in function 'scalb' i686-apple-darwin9-gcc-4.0.1: -framework: linker input file unused because linking not done i686-apple-darwin9-gcc-4.0.1: Tcl: linker input file unused because linking not done i686-apple-darwin9-gcc-4.0.1: -framework: linker input file unused because linking not done i686-apple-darwin9-gcc-4.0.1: Tk: linker input file unused because linking not done powerpc-apple-darwin9-gcc-4.0.1: -framework: linker input file unused because linking not done powerpc-apple-darwin9-gcc-4.0.1: Tcl: linker input file unused because linking not done powerpc-apple-darwin9-gcc-4.0.1: -framework: linker input file unused because linking not done powerpc-apple-darwin9-gcc-4.0.1: Tk: linker input file unused because linking not done And then it fails with: gcc -arch ppc -arch i386 -isysroot /Developer/SDKs/MacOSX10.4u.sdk -g - bundle -undefined dynamic_lookup build/temp.macosx-10.3-i386-2.6/ _imagingtk.o build/temp.macosx-10.3-i386-2.6/Tk/tkImaging.o -L/opt/ local/lib -L/usr/local/lib -L/Library/Frameworks/Python.framework/ Versions/2.6/lib -L/usr/lib -o build/lib.macosx-10.3-i386-2.6/ _imagingtk.so -framework Tcl -framework Tk ld: in /opt/local/lib/libz.1.dylib, file is not of required architecture for architecture ppc collect2: ld returned 1 exit status lipo: can't open input file: /var/folders/gO/gOEfKG2kElSEfJYMJH7ijU++ +TI/-Tmp-//ccpZdO98.out (No such file or directory) error: command 'gcc' failed with exit status 1 Is there a fix for this?

Rocket jumping up and down in the dock?

So sometimes when I run a Python service I get a rocket jumping up and down in the Dock for 30 seconds or so. Usually not, but sometimes. Any idea why this happens? I'm using the /usr/bin/python, consistently. Bill

py2app fails on /usr/bin/strip
by David Eyk Oct. 24, 2008

Oct. 24, 2008

The py2app command is failing for me with a very strange error: ======== /usr/bin/strip: for architecture i386 object: /Users/deyk/code/py/spaaace/trunk/dist/bash.app/Contents/MacOS/bash malformed object (unknown load command 8) stripping saved 18312668 bytes (12069072 / 30381740) ======== This leaves half-baked app bundle in the dist folder. I've googled the error, but I haven't been able to turn up anything understandable or python-related. I've replicated this behavior with a dummy package, which I'm attaching. I have the following environment: OS X: 10.4.11 Python: 2.5.1 setuptools: 0.6c9 py2app: 0.4.2 Can anyone else replicate this error with the attached package? Anyone have an idea what's going on, or how I might fix it? Thanks, David Eyk
