py2app annoyance
by Christopher Barker Jan. 27, 2010

Jan. 27, 2010

Hi all, I've often gotten errors like: /usr/bin/strip: the __LINKEDIT segment does not cover the end of the file (can't be processed) in: /Users/cbarker/HAZMAT/MappingSVN/Maproom/trunk/dist/Maproom.app/Contents/Frameworks/GDAL.framework/Versions/1.6/Programs/gdaltindex (for architecture ppc) They go away if I blow away the previously built app bundle and run it clean. This isn't too big a deal, but I often forget, and then I stare at it while before I remember what to do about it. Is there a bug tracker for py2app that I could put this in? -Chris -- 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

patch: make --app and --plugin work
by Attila Tajti Jan. 26, 2010

Jan. 26, 2010

Hello, I restarted my project from stratch starting with py2applet --make-setup and found that the --app and --plugin switches do not work. Without an argument they will be set to True. This will cause problems but py2applet --help is specific enough on this so I could figure out it needs an argument (at first I thought these are actually boolean options to select either an app or plugin to be built, but in fact they need an argument as the app/plugin name). The real problem however they do not work with an argument either, because build_app.py needs an argument here that is a list, so it will end up converting the string to list and ultimately fail. Anyway I attached a patch that fixes this problem, along with a typo ("puglin" -> "plugin"). p.s.: apparently these options worked when initially added on 2007-08-29 but later they were (perhaps accidentally) removed on 2008-01-06. p.s.2.: perhaps it would be nicer to handle the fact --app and --plugin arguments are strings in another place (ie. outside FixupTargets). I would be glad to do that upon request. Theoretically the best way to do it would be to expect only strings as "app" and "plugin" and it would work in py2applet --make-setup well, but in practice they could break existing setup.py scripts created earlier. -- Attila

shild App against crashes in call of PyRun_SimpleString

Hi, What is the best way to protect my app from crashes if something went wrong in a PyRun_SimpleString call. I get (very few) crash reports like the on below. Does someone know what is going on?

py-appscript: Rating a Song with Applescript
by William Reardon Jan. 19, 2010

Jan. 19, 2010

I'm attempting to programmatically rate a song in iTunes. I hacked together the following snippet in Applescript, but after reading the docs, I can't figure out how to convert the "every file..." mechanic to the py-appscript equivalent. Any suggestions? tell application "iTunes" set ts to (every file track of playlist "Library" whose name is track_name and artist is track_artist and album is track_album) repeat with t in ts set rating of t to track_rating end repeat end tell Thanks in advance, -Bill

Loading bridgesupport files - pyObjC
by Ben Jack Jan. 19, 2010

Jan. 19, 2010

Hi there, I am currently delving into pyObjC, but have been running into some difficulty's with using the bridgesupport files for the framework I am using. I have the basics working using objc selectors for example if I have a delegate function buttonChanged_isPressed_ (int1, int2) : buttonChanged_isPressed_ = objc.selector(buttonChanged_isPressed_, signature='v16@0:4i8B12') but It seems to me like this is just restating what the bridgesupport file has already defined (I don't think it is even being properly loaded when I load the framework). I could possibly keep defining these signatures for functions, but my problem is with the low level c structures which aren't understood by python. I have this project working fine in ruby, which reads the bridgesupport file when I load the framework and does all the dirty work as far as creating signatures for me. Essentially what I am asking is, is there any simple way to direct python to the bridgesupport file when I load up the framework, and does this negate the need to specifically create selectors for my delegate functions? cheers, Ben

(no subject)
by Karsten Wolf Jan. 15, 2010

Hi, I have an application which I created with python 2.5 and py2app on OSX 10.4.11. All is well. Trying to build it with python 2.6.4 and py2app 0.4.3 ends in pdb. python setup.py -A works. Analyzing the code snippet which causes the exception, one can see it calls a unix tool called 'ibtool' which is not present on my system. Seeing that the same tool is used for .xib files my guess is it belongs to Xcode 3.x. What can I do about it (without going to OSX 10.5 and Xcode 3) -karsten In py2app/converters/nibfile.py: p = subprocess.Popen(['ibtool', '--compile', destination, source]) python setup.py py2app: ... creating /Users/karstenwo/python/pyobjc/bildimporter-git/build/ bildimporter.app/Contents/Resources/English.lproj Traceback (most recent call last): File "/Library/Frameworks/Python.framework/Versions/2.6/lib/ python2.6/site-packages/py2app-0.4.3-py2.6.egg/py2app/build_app.py", line 589, in _run self.run_normal() File "/Library/Frameworks/Python.framework/Versions/2.6/lib/ python2.6/site-packages/py2app-0.4.3-py2.6.egg/py2app/build_app.py", line 660, in run_normal self.create_binaries(py_files, pkgdirs, extensions, loader_files) File "/Library/Frameworks/Python.framework/Versions/2.6/lib/ python2.6/site-packages/py2app-0.4.3-py2.6.egg/py2app/build_app.py", line 755, in create_binaries target, arcname, pkgexts, copyexts, target.script) File "/Library/Frameworks/Python.framework/Versions/2.6/lib/ python2.6/site-packages/py2app-0.4.3-py2.6.egg/py2app/build_app.py", line 1180, in build_executable copy_resource(src, dest, dry_run=self.dry_run) File "/Library/Frameworks/Python.framework/Versions/2.6/lib/ python2.6/site-packages/py2app-0.4.3-py2.6.egg/py2app/util.py", line 84, in copy_resource converter(source, destination, dry_run=dry_run) File "/Library/Frameworks/Python.framework/Versions/2.6/lib/ python2.6/site-packages/py2app-0.4.3-py2.6.egg/py2app/converters/ nibfile.py", line 27, in convert_nib p = subprocess.Popen(['ibtool', '--compile', destination, source]) File "/Library/Frameworks/Python.framework/Versions/2.6/lib/ python2.6/subprocess.py", line 621, in __init__ errread, errwrite) File "/Library/Frameworks/Python.framework/Versions/2.6/lib/ python2.6/subprocess.py", line 1126, in _execute_child raise child_exception OSError: [Errno 2] No such file or directory > /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/ subprocess.py(1126)_execute_child() -> raise child_exception (Pdb)

10.6: platform.mac_ver() broken
by Aahz Jan. 14, 2010

Jan. 14, 2010

After a lot of poking around, it appears that platform.mac_ver() is broken in 10.6 (Snow Leopard) because the gestalt module calls fork(), which causes a crash with USING_FORK_WITHOUT_EXEC_IS_NOT_SUPPORTED_BY_FILE_MANAGER. This seems to only happen with py2app builds; I have not been able to reproduce using strict command-line testing, and I haven't had time to create a stripped-down app to test with. I'd appreciate if someone else could verify before I file a bug. (It's possible that the multiprocessing module is involved if a simple test fails to reproduce -- my AppDelegate starts another process for the main code that then calls mac_ver() to log the current OS version.) I'm using os.uname() instead for now. -- Aahz (aahz(a)pythoncraft.com) <*> http://www.pythoncraft.com/ "If you think it's expensive to hire a professional to do the job, wait until you hire an amateur." --Red Adair

Here's the error message: > > TypeError: Can't install event handler 'CoKvdman': expected 2 parameters > but function 'getDomain' has 1. Ah, that would be a bug in aemreceive then. When you can installeventhandler it checks the function object's argument names list. It doesn't check it's an unbound function or bound method, however, so doesn't realise it should ignore the first argument name when validating the tuples that represent your AE-to-Python parameter bindings. I'll need to fix that, but it won't be soon as I'm really busy. For now, try commenting out the relevant validation code in aemreceive.main._processArgDefs: if len(argNames) != len(argDefs): raise TypeError, "Can't install event handler %r: expected %i parameters but function %r has %i." % (eventCode, len(argNames), callback.__name__, len(argDefs)) HTH has -- Control AppleScriptable applications from Python, Ruby and ObjC: http://appscript.sourceforge.net
