The attached patch removes all traces to os.name == 'mac' from the source tree (setup.py and stdlib), that is the leftover traces for MacOS9 support.

A simular patch needs to be created of the 3.x tree.

[ronaldoussoren]

The reason I'd like a patch review is that it affects a lot of files and want a second pair of eyes to check that I haven't been too agressive.

The patch itself doesn't cause regressions in the unittests.

Hello

Some removals are unfinished, e.g.

• if platform not in ['mac']: + if platform not in []:

→ remove the test and dedent the suite;

• if platform not in ['mac', 'win32']: + if platform not in ['win32']:

→ if platform != 'win32':

Regards

Removed traces of MacOS9 support in r80804 (trunk) and r80805 (3.2)

I’ve just noticed this problem:

--- a/Misc/BeOS-setup.py
+++ b/Misc/BeOS-setup.py
@@ -356,7 +356,7 @@ class PyBuildExt(build_ext):
                                    libraries = dblib) )

         # Unix-only modules
-        if platform not in ['mac', 'win32']:
+        if platform == 'win32':

The logic is reversed. Shall I fix it in all affected branches?
