While playing with a version of the patch which returns None for non-source
builds, I found that distutils.support._get_xxmodule_path() depends on
get_config_var('srcdir') always returning a string:
def _get_xxmodule_path():
srcdir = sysconfig.get_config_var('srcdir')
candidates = [
os.path.join(os.path.dirname(__file__), 'xxmodule.c'),
os.path.join(srcdir, 'Modules', 'xxmodule.c'),
os.path.join(srcdir, '..', '..', '..', 'Modules', 'xxmodule.c'),
]
for path in candidates:
if os.path.exists(path):
return path
It is easy enough to modify _get_xxmodule_path() to check for None. But this
does suggest that returning None might break some currently working 3rd party
code.
