For what it's worth, I've long since adapted to the status quo here, so I'm 
happy for this to just be closed :-).

(Apple seems to have mostly given up on "domains" as a user-facing or even 
developer-facing concept, so searching /Network seems like it is not relevant 
any more.  /System is now read-only even for root and they're deprecating the 
Python installed there; still, the up-to-date reference for the relevant API is

Please mention Apple's OS X Python behavior in the PEP. The Python that comes 
with OS X Lion doesn't seem to follow the PEP regarding ~/.local ; this 
deserves a mention.

[issue8084] pep-0370 on osx duplicates existing functionality

[Glyph Lefkowitz]

Glyph Lefkowitz gl...@twistedmatrix.com added the comment:

Would it be possible to have this reverted for 2.7.2 / 3.2.1, and restore 
~/.local _and_ ~/Library as equally valid locations for python code?

As I tried to explain on the mailing list, this change basically introduces a 
regression, and nothing else.  Sorry I did not comment on the ticket at the 
time.

Previously it was possible to maintain a single ~/.pydistutils.cfg for 
UNIX-like OSes, which would allow 'python setup.py install', 'pip install' and 
'easy_install' to function without adding a 'sudo' in front of them, or any 
command-line options.  This is important since easy_install doesn't expose a 
'--user'.  Now, there needs to be a specific, separate config file for OS X 
installs.

Also, it was previously possible to pass a sane value for '--prefix', but now 
there is no such value.  This makes it much more difficult to, for example:

  cd my-c-dependency
  ./configure --prefix ~/.local
  cd my-python-project
  python setup.py install --prefix ~/.local

since Python code with C dependencies will sometimes attempt to discover the 
location of include files and the like via the install prefix.

'setup.py install --user' (the only remaining installation mechanism which 
actually works out of the box on a mac) will now place scripts into 
~/Library/Python/x.y/bin, which seems a singularly unhelpful location.  Again, 
if there are C and Python programs which interact, I now need 2 locations on my 
$PATH instead of one.

I don't understand what this change buys anyone.  If you're treating the Mac 
python as a UNIX-like environment, it just spuriously breaks things.  But if 
you're treating it as a Mac-like environment (i.e. not using a terminal), the 
right place to put your Python code is _inside a (framework or application) 
bundle_, not lying around your home directory.

Also, if there is interest in properly honoring Mac filesystem conventions, 
there are APIs for doing that, as documented here: 
http://developer.apple.com/library/mac/#documentation/MacOSX/Conceptual/BPFileSystem/Articles/Domains.html.
  Manually enumerating the user domain while ignoring, for example, the network 
domain, seems half-hearted and arbitrary.

Any ideas why?  This is on a non-framework debug build of the trunk.  The 
variable 'dirs' turns out to be:

['Python.framework/lib/python2.7/site-packages', 
'Python.framework/lib/site-python']

What else should be there?

@Sean: you can look at the maintainers.rst file in the py3k branch I guess

I am maintaining sysconfig, so I guess I'll just help on the review.

Notice that we might need to backport some of the work in distutils/sysconfig 
since we have decided to revert distutils to 2.6/3.1 state in 2.7/3.2. I'll 
wait for Christian reviews, and make sure that this part is OK

[issue8084] pep-0370 on osx duplicates existing functionality

[Ronald Oussoren]

New submission from Ronald Oussoren ronaldousso...@mac.com:

The implementation of pep-0370 treats OSX like any other unix platform. 

This is problemantic for two reasons: first of all OSX already had a per-user 
directory before pep-0370 was implement: ~/Library/Python/X.Y, which means 
there are now two per-user directories on OSX. Secondly the pep-0370  per-user 
directory does not honor platform conventions.

I therefore propose to change pep-0370 behavior on OSX: 
* remove ~/.local as the user-base
* upgrade ~/Library/Python/X.Y to a pep-0370 compatible directory
  (that is: introduce the additional subdirectories that are used
   in pep-0370)
* upgrade /Library/Python/X.Y to the same structure

[Ronald Oussoren]

Ronald Oussoren ronaldousso...@mac.com added the comment:

The attached patch is untested an implements the proposed behavior for 
framework builds, unix builds would keep the unix-style behavior (and would 
lose access to ~/Library/Python).

The patch is slightly complicated by adding support for --with-framework-name 
as well, but that shouldn't make the patch harder to read.

BTW. The needs review part is more for the proposed change in behavior that 
for the actual patch, I'm confident that I can create a correct patch but I'm 
not sure if the change is behavior is uncontroversial.
