Brett Cannon added the comment: So I tried extracting out the check by implementing a path_mtime() method on FileFinder, but then I realized it would simply be easier to abstract out _os.stat() to _path_stat() and let people cache stat calls at the global level, which would have a side-effect of never refreshing the path cache. Otherwise all of the other experiments I tried with minimizing stat calls didn't buy me much according to the benchmarks.
I have also attached a patch which abstracts all file system code that passed through _os into a class. It didn't buy me much plus added a little overhead thanks to the extra abstraction, so I did not bother to commit it. ---------- keywords: +patch resolution: -> rejected status: open -> closed Added file: http://bugs.python.org/file32452/OO_os.diff _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue18809> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
