Summary: pythonpath registry value ignored in 2.0

Details: The value of the HKLM\software\python\pythoncore\2.0\pythonpath
key is now ignored in Python 2.0 unless you have at least one subkey
underneath it. Since the default installation program doesn't add any
subkeys, users familiar with 1.5.2 who expect to just set pythonpath
in the registry will be disappointed.

I imagine that you all probably run with other extensions installed that
add subkeys under pythonpath and thus never see this bug. However, the
first thing I did after installing 2.0 was to try to point to my custom
libs. 5 hours later I can finally start testing to see if they still work
:).

This problem is undoubtedly related to bug 127722. Fix that and you'll fix
this one.

Comment:
I can not reproduce this.  I believe the "problem" is that since Python
1.6, Python's registry search mechanism has changed.  If Python can locate
its own "home" (which it usually can, given a vanilla install) then it
_ignores_ the main registry key, and _only_ looks in subkeys.  The
rationalle is that this will allow you to have multiple installations of
the same Python version (eg, the "official" release and the current CVS
version).  This will ensure the "core" path is always correct.

To test this, copy "python.exe" to a temp directory, and run it from there.
 In this case Python will not be able to locate its home, and will use the
registry key.

I am leaving this bug open to remind me to add documentation on the
registry somewhere appropriate.  However, I am marking as "works for me".

Mark?  You know more about this than everyone else combined.  Is that good
news or bad <wink>?
