[Pythonmac-SIG] Python 2.7b2 framework install

[Michiel de Hoon]

I tried this again on Mac OS X 10.5 and found that the Python inside Python.app works as a framework, but python and pythonw do not:

$ /Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python 
Python 2.7b2+ (trunk:81635, Jun  1 2010, 20:39:42) 
[GCC 4.0.1 (Apple Inc. build 5465)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import MacOS
>>> MacOS.WMAvailable()
True
>>> ^D


$ which python
/Library/Frameworks/Python.framework/Versions/2.7/bin//python

$ python
Python 2.7b2+ (trunk:81635, Jun  1 2010, 20:39:42) 
[GCC 4.0.1 (Apple Inc. build 5465)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import MacOS
>>> MacOS.WMAvailable()
False
>>> ^D

$ ls -l /usr/local/bin/python
lrwxr-xr-x  1 root  wheel  60 Jun  1 20:42 /usr/local/bin/python -> /Library/Frameworks/Python.framework/Versions/2.7/bin/python

$ /usr/local/bin/python
Python 2.7b2+ (trunk:81635, Jun  1 2010, 20:39:42) 
[GCC 4.0.1 (Apple Inc. build 5465)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import MacOS
>>> MacOS.WMAvailable()
False
>>> ^D

If I move python2.7 from /Library/Frameworks/Python.framework/Versions/2.7/bin to /Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python, then I can run python2.7 as a framework.

So I guess what is happening is that because of the use of posix_spawn in pythonw in Python 2.7, the executable is in /Library/Frameworks/Python.framework/Versions/2.7/bin, instead of inside Python.app, so it doesn't interact appropriately with the window manager. Python 2.6 uses execve in pythonw, so /Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python is the executable, and behaves as a framework.
