[New-bugs-announce] [issue23734] zipimport should not check pyc timestamps against zipped py files

[Gregory P. Smith]

New submission from Gregory P. Smith:

The zipimport module checks the timestamp of a pyc file loaded from the zip file against the timestamp of a corresponding py file in the zip if any.  This seems pointless.  By the time someone has created a zip file for zipimport they should have guaranteed that the pyc's are fresh or not have put them into the zip file at all (wasteful).

There is a comment in the code alluding to this, but the mtime check is still done right above.
