readline on OS X 10.4 on Intel?
by Simon Willison Aug. 17, 2006

Aug. 17, 2006

Hi, I've just got my hands on a MacBook Pro, but the old trick for getting readline running for Python no longer works: $ python `python -c "import pimp; print pimp.__file__"` -i readline Traceback (most recent call last): ... <snip> ... urllib2.HTTPError: HTTP Error 404: Not Found Further investigation shows that the URL in question is: http://www.python.org/packman/version-0.5/prod-2.3-darwin_apple-8.7.1-i386.… The files in http://www.python.org/packman/version-0.5/ haven't been touched since April of last year. What's the current recommended way of getting readline running with the python 2.3.5 that comes with Intel macs? Cheers, Simon Willison

examples of python
by Mark Phillips Aug. 16, 2006

Aug. 16, 2006

I apologize if this is off topic. I have been researching the following and I thought of this group. I am preparing a presentation about using python to extend existing applications. One of the things I will attempt to show is the power of OSS. That is, the availability of a wide variety of "ready to use" applications. Not applications in the sense of complete desktop applications, but rather code that handles the edges and nuance of business applications. A few areas are well covered. Database, UI framework and web service examples are plentiful. What I seek is the more esoteric. Examples that would be interesting to an experienced business database application developer who has a well stocked set of tools. And who is just learning about python. I have a handful of examples based on my own work. I am hoping that a few of you on the list might be willing to offer suggestions and links that would add breadth and interest to the presentation. Please feel free to contact me off list if you prefer. TIA, Mark Phillips

py2app build problems
by William Kyngesburye Aug. 12, 2006

Aug. 12, 2006

I have a setup.py I generated from py2applet which I've expanded to copy in all the shell scripts and binaries and support files needed for an application (py2app is just for the app startup, the app is all shell scripts and C binaries). - I have dylib_excludes worked out so it doesn't pull in a bunch of extra frameworks (3rd party stuff) that are expected to be installed separately. One odd thing there, before I excluded them: a couple frameworks are wrappers (umbrella framework) for a collection of unix libraries or make use of a bunch of unix libraries, included in the framework. py2app copied the whole framework, then duplicated the included libraries needed by the framework in the top level of the Frameworks folder, like (simplified): Contents Frameworks Foo.framework Libraries libbar1.dylib libbar2.dylib Foo [uses libbar1 and libbar2] libbar1.dylib [Foo's new relative @executable_path libbar2.dylib linking uses these copies] If I wanted to include the frameworks, it would be a mess. - the dylib exclude option is not working for dylibs, just frameworks. I've tried various forms: the full path as specified in the install name, libfoo, libfoo.dylib, libfoo.version.dylib. It still copies them. - for libraries installed from the software, it's pulling in installed copies (makes sense, since that's where the install name has them). But these may be older than the ones I've just built for the app package and haven't installed yet. given the various issues with pulling in libraries and frameworks, an exclude option that would be nice is to exclude all libraries/ frameworks, without having to figure out what they might be and listing every one, a 'dylib_excludes: all' option. I would rather install needed libraries manually anyways (as resources), and the application sets DYLD_LIBRARY_PATH already so relative paths aren't needed. ----- William Kyngesburye <kyngchaos(a)kyngchaos.com> http://www.kyngchaos.com/ "This is a question about the past, is it? ...

py2app run errors
by William Kyngesburye Aug. 11, 2006

Aug. 11, 2006

I have a python script that sets a couple environment vars and runs a shell script in a Terminal window. It works when run from a Terminal with 'python doshell.py'. But when packaged into an app with py2app I get errors. Here's a simplified version (doshell.py): #!/usr/bin/env python import sys import os base = os.path.dirname(sys.argv[0]) # options used by myshell.sh (can't use args) os.environ['STARTBASE'] = base os.environ['MYOPTION'] = 'shelloption' shellrun = base + '/myshell.sh' os.execlp('open', 'open', '-a', 'Terminal.app', shellrun) # continue doing python stuff... The error I get: Traceback (most recent call last): File "/Users/Shared/src/myshell/dist/doshell.app/Contents/ Resources/__boot__.py", line 137, in ? _run('doshell.py') File "/Users/Shared/src/myshell/dist/doshell.app/Contents/ Resources/__boot__.py", line 134, in _run execfile(path, globals(), globals()) File "/Users/Shared/src/myshell/dist/doshell.app/Contents/ Resources/doshell.py", line 18, in ? os.execlp('open', 'open', '-a', 'Terminal.app', shellrun) File "/Library/Frameworks/Python.framework/Versions/2.4/lib/ python2.4/os.py", line 324, in execlp execvp(file, args) File "/Library/Frameworks/Python.framework/Versions/2.4/lib/ python2.4/os.py", line 341, in execvp _execvpe(file, args) File "/Library/Frameworks/Python.framework/Versions/2.4/lib/ python2.4/os.py", line 379, in _execvpe func(fullname, *argrest) OSError: [Errno 45] Operation not supported 2006-08-10 12:11:34.918 CommandDroplet[409] doshell Error 2006-08-10 12:11:34.919 CommandDroplet[409] doshell Error An unexpected error has occurred during execution of the main script I've built the app with the semi_standalone option, and the myshell.sh script is also installed in the app with the resources option in py2app. Built completely standalone, same error, except that the os.py lines have no path. I tried using spawnlp instead, but in the Terminal AND in the py2app application I get the error: RegisterProcess failed (error = -50) I'm just getting my feet wet with Python, so I wouldn't be surprised if I did something wrong here. Maybe there's a better way to run the shell script in a Terminal. Maybe something is wrong with argv[0] when run from the app so the path to run the shell script is wrong. The error isn't very helpful. ----- William Kyngesburye <kyngchaos(a)kyngchaos.com> http://www.kyngchaos.com/ All generalizations are dangerous, even this one.

Permission of package installed by mpkgs...
by Christopher Barker Aug. 9, 2006

Aug. 9, 2006

Hi all, I just helped a friend install the PIL mpgk from: http://www.pythonmac.org/packages/py24-fat/ On an OS-X 1-0.4.* Intel Mac. After installing, "import Image" still didn't work, so we went poking into /Library.Frameworks,.....etc, and found that indeed, the PIL dir and PIL.pth has been installed in site-packages, but that neither had read permissions for anyone but the owner, and the owner was set to "localadm", rather than "root" or the name of the user that ran the installer. When we added read permissions for all, it now works fine, but what the heck is going on? By the way, we were not asked for the admin password when running the installer. On my machine (PPC 10.4.7), I notice that PIL is owned by me (the user that installed it), but also has no read perms for anyone but the owner. As I'm the owner, it works for me, but that doesn't seem right. One other difference between the two machines: I think my friend's is set up to authenticate off a Windows Domain controller, which might have something to do with why his got installed by "localadmin", rather than himself. As I look at my site-packages dir, things are a bit messy. Most stuff is owned by me, with a smattering owned by root, but all have a+r perms, except PIL. this stuff is a mixture of packages installed from mpkgs and regular old setup.py install. What's going on? How should this work? I have no idea how, but my thought is that mpkgs should ask for a password, then install as root. Of course with the appropriate read permissions. -Chris -- Christopher Barker, Ph.D. Oceanographer NOAA/OR&R/HAZMAT (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

Re: [Pythonmac-SIG] appscript with todos in iCal seams very slow

Apple event IPC is fairly expensive; asking applications to resolve lots of object model 'references' (i.e. queries) especially so. Sending a few complex queries is usually much, much quicker than sending lots of simple ones, e.g. the following will pull all property values from all todos in a single go: todos = appCal.calendars.filter(its.name != '').todos.properties() You can then rearrange this data in Python to suit your needs. There's more information in the appscript manual: chapters 2 and 3 discuss how Apple events and the Apple Event Object Model work; chapter 12 discusses various optimisation techniques for getting good performance out of the system.

[py2app] "An unexpected error has occurred during execution of the main script"
by Michael Glassford Aug. 8, 2006

Aug. 8, 2006

I get this error running a py2app alias build (one built with option alias=True) of an application, with the additional information "AttributeError: 'NoneType' object has no attribute 'endswith'; See the Console for a detailed traceback." However, no additional information is written to the console. This alias build had been working for a long time. As far as I know, there have been no recent configuration changes that should cause this problem. If I make a non-alias build, it runs as it should. As far as I can tell, this error happens before site.py, __boot.py__ are executed: if I put print statements at the top of these files, nothing is printed. I suppose that's what "during execution of the main script" means? So my question is, how do I debug what's causing this problem? Mike

appscript 0.16.0 source release
by has Aug. 8, 2006

Aug. 8, 2006

Hi folks, I've posted the source for appscript 0.16.0 at: http://freespace.virgin.net/hamish.sanderson/appscript_source.html There's some API breakage in this version while I tidy stuff up (I want to freeze the aem and appscript APIs shortly) and a whole heap of other changes including bug fixes and performance optimisations, so I'd appreciate it if folks here could give it a bit of a whirl before I do the proper binary release. Please see the readme file for more details. ... Also, one more query: anyone have any strong opinions on whether I should stick with the current built-in type names (k.Integer, k.Float, k.String, k.Unicode, etc.) or switch to AppleScript- equivalents (k.integer, k.real, k.string, k.Unicode_text, etc.)? - Switching would simplify standardisation, especially if appscript gets ported to other platforms, since everyone is on the same wavelength. It also makes sdefs a bit easier to parse, since you only need to escape existing type names instead of converting them from AS keywords to AE codes to custom type names. - OTOH, folk may prefer that type and class names are easier to tell apart by their capitalisation (e.g. k.Type and k.document_file are more obviously different than k.value_class and k.document_file). Thanks, has -- http://freespace.virgin.net/hamish.sanderson/
