Authentication via python?
by Benjamin Schollnick Aug. 21, 2009

Aug. 21, 2009

Folks, I¹m working on some time machine scripting... In a gist, there is a .Backup.log file that I want to access via readline & python.... >From the MOSX gui, it appears some of the files require root access (eg. Authentication dialog pops up). Now, I am using the applet maker to compile the python to a GUI stub, so I can¹t SUDO the python script... Is there some method that I can use to authenticate via the python script internally? I¹m in the middle of a google search on this, but I am having no luck at refining my search phrase currently (Macintosh python authenticate)... - Benjamin

App distribution with eggs
by David Woods April 27, 2009

April 27, 2009

I'm updating my development tools for an application I've been distributing for a few years now. One of my critical imports, MySQLdb, gets built as an egg under by new system. In the past, I've used BundleBuilder for making my distributable app for the Mac and it's worked admirably. I can't figure out how to get BundleBuilder to include the MySQLdb egg, (I get "ImportError: no module named MySQLdb") and it looks to me like py2app doesn't support eggs either. My (perhaps inept) Googling hasn't revealed any likely suspects. What method do folks recommend for building distributable apps which have dependencies on eggs? David

Re: [Pythonmac-SIG] Py2App and PyQT
by kelsolaar_fool＠hotmail.com Jan. 23, 2009

Jan. 23, 2009

Ok the QtCore.so problem got solved by adding this line into the __boot__.py : sys.path = [os.path.join(os.environ['RESOURCEPATH'], 'lib', 'python2.5', 'lib-dynload')] + sys.path Now I'm facing another really annoying problem : I need at some point to load jpeg images into my program and Qt jpeg support is done from a plugin library : libqjpeg.dylib under MacOsX and qjpeg4.dll on Windows. On Windows in order to make my packaged program use it (compiling with py2exe) I include a qt.conf file at the root of my software with this as content : [Paths] Prefix = ./PyQt4 Binaries = . and the dll is here : PyQt4\plugins\imageformats\qjpeg4.dll This is working fine, I tried the same or a lot of different locations and combinations on MacOsX and everything failed, resulting in blank thumbnails in my program. That is really annoying and can really compromise the release of it on Mac. Hope someone as an idea ? Thanx, Thomas

py2app and PyQt4
by Jeremy Sanders Dec. 2, 2008

Dec. 2, 2008

Hi - I'm having problems with my PyQt4 application which uses pyuic dynamically to load in dialogs. Firstly py2app doesn't seem to include sip in the output dist, but does include PyQt4. Presumably it should work out that PyQt4 is dependent on sip. I can fix this with an explicit import sip, but maybe it should automatically include sip for PyQt4. The second problem is that it isn't properly handling this code in PyQt4: try: from xml.etree.cElementTree import parse, SubElement except ImportError: try: from cElementTree import parse, SubElement except ImportError: try: from elementtree.ElementTree import parse, SubElement except ImportError: from PyQt4.elementtree.ElementTree import parse, SubElement It fails when running the app on the final import, even though it should successfully be doing the first xml.etree.cElementTree import from the first line. I tried an explicit xml.etree.cElementTree import elsewhere in the code but this doesn't fix the problem. The other issue is in my code. To allow users to run the app without installing it, I have this code in the main script: # Allow veusz to be run even if not installed into PYTHONPATH try: import veusz except ImportError: # load in the veusz module, but change its path to # the veusz directory, and insert it into sys.modules import __init__ as veusz thisdir = os.path.dirname( os.path.abspath(__file__) ) veusz.__path__ = [thisdir] veusz.__name__ = 'veusz' sys.modules['veusz'] = veusz It doesn't process the program properly with this code. If I replace this block with just "import veusz" it works. This doesn't make much sense to me. I have another problem with an extension module, but I will save that for another email.

I configured like so: ../configure --enable-framework='/Users/skip/Applications' \ --enable-shared --prefix='/Users/skip/local' \ CPPFLAGS='-I/Users/skip/local/include -I/opt/local/include' \ LDFLAGS='-L/Users/skip/local/lib -L/opt/local/lib' No .dylib file was created. I ran make altinstall then checked in both /Users/skip/Applications/Python.framework and in ~/local. Still no Python .dylib files. Then I scoured the Makefile looking for promising targets to try. I tried making both sharedmods and sharedinstall. Nothing. Thinking the --enable-framework and --prefix flags might mess up configure in some way I reconfigured without specifying --prefix. make clean. make sharedinstall. Still no dylib files. Any other ideas I might try? I finally just submitted a bug report: http://bugs.python.org/issue4472 Thanks, Skip

Creator, type and other means of file detection
by Henning Hraban Ramm Nov. 30, 2008

Nov. 30, 2008

I know the MacOS module is deprecated, and now I know at least one detail of "why": If I use MacOS.GetCreatorAndType(filename) on my Intel machine, I get for an EPS: ('09HF', 'FSPE') That should read ('FH09', 'EPSF'). I didn't knew endian-ness affects the order of strings. Very funny! ;-) I'm trying once again to write a tool to detect the type of a file - my colleagues don't know what to do if a file lacks an extension or has a wrong one. Unfortunately the "file" command and its Python counterparts don't know enough and the right types, e.g. for them a XPress or InDesign document is just "data". (There are two different approaches of "magic.py": Jason Petrone's, updated by Gabriel Wicke, uses its own, pythonized list of magic numbers; the other by Thomas Mangin reads the usual Unix/Linux magic files and thus acts like the "file" command. I guess the first is much faster, but the second is more versatile.) Anyway, the traditional MacOS type and creator would be a nice addition. The MacOS module is deprecated. I could ask the Finder via appscript, but I wonder if there's a more direct way - I'm surprised the mactypes module's Alias and File classes don't know type and creator. Any ideas on that? Greetlings from Lake Constance! Hraban --- http://www.fiee.net https://www.cacert.org (I'm an assurer)

Can't convert simple Python script to bundle with py2app
by skip＠pobox.com Nov. 28, 2008

Nov. 28, 2008

I have a trivial little script: #!/usr/bin/env python import os import sys os.execl("/Users/skip/local/bin/gnuclient", *sys.argv[1:]) which I want to convert to a .app bundle. I downloaded and installed py2app using easy_install, successfully ran py2applet to generate a setup.py file: """ This is a setup.py script generated by py2applet Usage: python setup.py py2app """ from setuptools import setup APP = ['rungnucl.py'] DATA_FILES = [] OPTIONS = {'argv_emulation': True} setup( app=APP, data_files=DATA_FILES, options={'py2app': OPTIONS}, setup_requires=['py2app'], ) then ran "python setup.py py2app" which gave me a traceback and dropped me into pdb: ... copying /Users/skip/local/lib/python2.7/lib-dynload/unicodedata.so -> /Users/skip/tmp/dist/rungnucl.app/Contents/Resources/lib/python2.7/lib-dynload copying /Users/skip/local/lib/python2.7/lib-dynload/zlib.so -> /Users/skip/tmp/dist/rungnucl.app/Contents/Resources/lib/python2.7/lib-dynload copying /Users/skip/local/bin/python -> /Users/skip/tmp/dist/rungnucl.app/Contents/MacOS Traceback (most recent call last): File "/Users/skip/local/lib/python2.7/site-packages/py2app-0.3.6-py2.7.egg/py2app/build_app.py", line 548, in _run self.run_normal() File "/Users/skip/local/lib/python2.7/site-packages/py2app-0.3.6-py2.7.egg/py2app/build_app.py", line 619, in run_normal self.create_binaries(py_files, pkgdirs, extensions, loader_files) File "/Users/skip/local/lib/python2.7/site-packages/py2app-0.3.6-py2.7.egg/py2app/build_app.py", line 723, in create_binaries mm.mm.run_file(runtime) File "build/bdist.macosx-10.3-i386/egg/macholib/MachOGraph.py", line 65, in run_file raise ValueError('%r does not exist' % (pathname,)) ValueError: '/Users/skip/local/lib/libpython2.7.dylib' does not exist > /Users/skip/tmp/build/bdist.macosx-10.3-i386/egg/macholib/MachOGraph.py(65)run_file() (Pdb) Python (from Subversion trunk in this case) was configured using --enable-shared, but there is no libpython2.7.dylib to be found anywhere inside of the --prefix directory.

Python-Ogre on Mac OS X?
by Joe Strout Nov. 27, 2008

Nov. 27, 2008

I've just stumbled across the Python-Ogre project (http://www.pythonogre.com/ ). It looks fantastic, but the only binary is for Windows. That seems a little silly for a set of cross-platform-language bindings to a cross-platform library. :) There are older build instructions for Mac OS X available, as well as Linux (and pretty much anything that works on Linux can be made to work on OS X). And of course OS X has high-quality OpenGL drivers built in, and a great uniformity of hardware and OS configurations compared to Linux or Windows. So it ought to be fairly easy to keep this running well on the Mac, enabling great Python 3D game development that's truly cross-platform. But I don't know if I can do all that myself... is anyone else here interested in this? Perhaps we could share the maintenance. Best, - Joe
