py-appscript 0.20.3
by has Nov. 25, 2009

Nov. 25, 2009

Hi all, Just checked in rev. 69 which contains a couple of 64-bit bug fixes along with a workaround for OS 10.6's return ID bug. Unfortunately, I don't have time to do a thorough test, particularly of 32- and 64-bit support on Python 3.1.1 (the python.org framework distro is 32-bit only), and I don't want to do a new release until it's been checked properly. If any appscript users here are willing to give it a workout (Python 2.3-3.1.1, 10.4-10.6, 32-bit PPC/i386, x86-64) and let me know if everything's okay or if any issues are still outstanding, I'd really appreciate it. Thanks, has -- Control AppleScriptable applications from Python, Ruby and ObjC: http://appscript.sourceforge.net

Py2app error with libpng
by Brian Zambrano Nov. 24, 2009

Nov. 24, 2009

Hi there, I'm building an app with py2app and it runs successfully both on my computer and a friends. We both have the developer tools installed. On two other Macs, the application would die when loading one of the matplotlib .so files. The problem is that the .so, matplotlib/_png.so, is linking to: /usr/X11/lib/libpng12.0.dylib ...which doesn't exist on the two machines where the crash is occurring. My understanding is that py2app (or, macholib?) tries to resolve these dependencies and copy over the necessary dylibs. I've tried adding /usr/X11/lib/libpng12.0.dylib to the build with the 'frameworks' argument, but that doesn't seem to do anything. Now, I'm thinking of doing a manual copy of that file into the Framework directory, along with using install_name_tool. What's the best way to handle this? BZ

The problem i was having was that even though it builds without 2.6 but it doesn't see any modules. If i do: $ python Python 2.6.2 (r262:71600, Apr 16 2009, 09:17:39) [GCC 4.0.1 (Apple Computer, Inc. build 5250)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import kptools >>> My modules in my pythonpath load and i can see the whole namespace of that module just fine. but if i try to access the same module with the same version of python (via rtcmix) $ /Users/kp8/RTcmix-all/bin/PYCMIX < /Users/kp8/rtcmix/ stereo-sfp.py --------> RTcmix 4.0.1 (/Users/kp8/RTcmix-all/bin/PYCMIX) <-------- Traceback (most recent call last): File "???", line 6, in <module> ImportError: No module named kptools kp8[521]$ It doesn't see anything. Now it may be that i would have the same problem on python2.5 but the folks on the cmix list told me that i was making it much more complicated by trying to build it around 2.6 and that i should try to get it built on the Apple supplied 2.5 first, but truth be told, i would *LOVE* to get this working on 2.6 since i then would not have to jigger any of my 2.6 code (all those enumerates i used would have to be change for one! ugh!) That PYCMIX is not seeing any of my modules is perhaps not a 2.5 -v- 2.6 problem. Any thoughts on that? I get very confused on setting the path and also am really new to bash: # Setting PATH for MacPython 2.5 # The orginal version is saved in .bash_profile.pysave # ----export PATH=~/bin:~/python:/usr/local/RTcmix/bin:/Library/ Frameworks/Python.framework/Versions/Current/bin:$PATH export PATH=$PATH:/Users/kp8/bin:/Users/kp8/python:/Users/kp8/python/ svg:/Library/Frameworks/Python.framework/Versions/Current/bin:~/ Library/Application\ Support/NodeBox:/Users/kp8/nodebox:/Users/kp8/ mod:/Users/kp8/rtcmix: # Setting PATH for MacPython 2.6 # The orginal version is saved in .bash_profile.pysave PATH="/Library/Frameworks/Python.framework/Versions/2.6/bin:/Users/kp8/ rtcmix:${PATH}" export PATH

[ann] appscript 0.20.2
by has Nov. 21, 2009

Nov. 21, 2009

Hi all, Just posted a minor appscript update on PyPI that addresses some of the shortcomings of the osax module when used in 64-bit mode. http://www.python.org/pypi/appscript In addition to fixing a bug that prevented it targeting the current process, I've also added a static glue for OS X's Standard Additions (as that's all most folk use it for anyway) so you no longer need to generate a static glue yourself before using that particular osax. I've also added some notes to the README and to the py-appscript/install.html page on the website about building appscript for python.org distributions on 10.6. (Basically cribbed from Ned's last couple posts, cheers.) It's not an appscript-specific issue (it applies to all source distributions that include C extensions), but I know it's been giving some appscript users problems, so hopefully this will help. If anything's unclear or incorrect, just let me know and I'll improve it. Enjoy, has -- Control AppleScriptable applications from Python, Ruby and ObjC: http://appscript.sourceforge.net

2.5 -v- 2.6 conflicts on 10.5.x
by kevin parks Nov. 20, 2009

Nov. 20, 2009

I am trying to compile an audio package that imbeds python. One issue is that it apparently expect to find apple's built in python (i am on 10.5.8 here no snowkitty yet) but I also have 2.6 installed. So when i do the ./configure --with-python make make install and run a script this at the top i get: import sys print 'Python %s on %s (%s)' % (sys.version.split()[0], sys.platform.title(), sys.prefix) for item in sys.path: print item I get: Python 2.6.2 on Darwin (/Library/Frameworks/Python.framework/Versions/ 2.6) ok so that is no good. If i do the make clean make distclean ./configure --with-python=/usr/local/bin/python2.5 make make install or even ./configure --with-python=/usr/bin/python etc.... I *still* get: Python 2.6.2 on Darwin (/Library/Frameworks/Python.framework/Versions/ 2.6) It seems like no matter what i do, when the binary is built, it is compiled around 2.6. For those of you on 10.5 with the Apple and 2.6.x Python.... how do you point to one or the other? And when you install 2.6 does it move stuff around or fiddle with your frameworks or whatever? Folks who have 10.5.x and only the Apple supplied Python (2.5.x) are able to build this right out of the box, plug and chug. Folks who have 2.6 and Apple's build can't seem to compile this package correctly. Any thoughts at all? The package is RTcmix (found @ RTcmix.org)

Snow Leopard: productive procrastination

Howdy, If you tried getting a PyObjC app running on 10.6 a couple of months ago and gave up, you should try again now. I just ran software update and my app works fine now, without any changes (still building on 10.5). -- Aahz (aahz(a)pythoncraft.com) <*> http://www.pythoncraft.com/ "Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it." --Brian W. Kernighan

appscript CommandError timeout - always before 2**16 transactions, sometimes well before
by ken manheimer Nov. 18, 2009

Nov. 18, 2009

hi, all! i'm very happy to be using appscript for a general iTunes playlist synchronizer <http://myriadicity.net/Sundry/ItunesPlaylistSync>, for copying iTunes playlists and tracks to filesystem directories. i've hit upon what seems to be a hard and unexpected transaction limit, and worse, one which occasionally is aggravated and becomes a problematically low limit. i'm hoping that this is an appropriate forum for appscript issues - please let me know if there's a better place to post this. the behavior is an appscript.reference.CommandError timeout after some number of appscript transactions. there seems to be a hard limit just before 2**16 (65536) commands (actually, at 65529 commands, but i presume the difference is accounted for by preliminary setup). the limit is sometimes lower, even across separate python sessions, to somewhere a bit above 55,000, and in fact tends to be lower once the high limit has been hit. occasionally the limit is as low as tens or hundreds of transactions, at which point working with appscript is untenable and i need to reboot my machine to clear it. i only have one mac to test it on, so i haven't even confirmed it occurs for anyone else. the machine is only a few months old, so doesn't have too much cruft, and it happens in every python i've tried on the machine. (i've reproduced the problem with the appscript 0.20.0 installed via easy_install on the leopard system python 2.5.4, snow leopard system python 2.6.1, a 2.6 python built from scratch, etc; the machine is a 2.66 GHz macbook pro.) i'd be very interested to hear whether it occurs for others, and to make it easy for you to try: def first_timeout(): """Gratuitous itunes appscript reference cycle to elicit a timeout. It usually happens on some systems after just about 2**16 (= 2**2**2**2) interactions, and sometimes substantially before that.""" import appscript import sys itunes = appscript.app('itunes') t = itunes.tracks[1] count = 0 class PassedLimit(Exception): pass try: while True: count += 1 if count % 1000 == 0: sys.stderr.write("%i\n" % count) if count > 65530: sys.stderr.write("%i\n" % count) elif count > 66000: raise PassedLimit x = t.name.get() except appscript.reference.CommandError: sys.stderr.write("got a CommandError at count %i\n" % count) raise except PassedLimit: sys.stderr.write("exceeded threshold without triggering the timeout\n") to try it, paste the function into a mac python session (with appscript installed) and invoked 'first_timeout()'. if you have iTunes populated with at least one track, you'll see a count emitted at every 1000 transactions, and either a hang and then "got a CommandError ..." message followed by a traceback, if the error is encountered, or else an "exceeded threshold ..." message if the limit was passed without triggering the timeout. while i'm curious about the reason for the high hard limit, the reduced limits are actually a problem - even the 57000/58000 ceiling interferes with my script operation when running against a lot of playlists and tracks (88/9300), to the point that i've had to include kludgy measures to work around the problem. i'd love it if the problem could be confirmed by others, and if it's widespread, whether someone familiar with appscript internals could look into repairing it. (i'm also interested in having others try out the playlistsync script<http://myriadicity.net/Sundry/ItunesPlaylistSync>. this is my first public release of it, and i'd be happy to have people comfortable with python and appscript use it, so if you use iTunes and have a non-apple music player you'd like to sync, please consider trying it out!) -- ken manheimer http://myriadicity.net
