[Python-Dev] path joining on Windows and imp.cache_from_source() (original) (raw)

Now that we can reuse os.path.join() (directly for sourcefromcache(), indirectly through easy algorithmic copying in cachefromsource()) do we want to keep the "special" semantics, or can I change it to match what ntpath would do when there can be more than one path separator on an OS (i.e. not do anything special)?

This goes back to

http://codereview.appspot.com/842043/diff/1/3#newcode787

where Antoine points out that the code needs to look for altsep.

He then suggests "keep the right-most of both". I don't think he literally meant that the right-most separator should then also be used to separate pycache, but only that the right-most of either SEP or ALTSEP is what separates the module name.

In any case, Barry apparently took this comment to mean that the rightmost separator should be preserved.

So I don't think this is an important feature.
