It doesn't need to - if there is no file for the module in the cache, it assumes that the cache could be out of date and rebuilds it. If that turns up a file, then fine, else the module doesn't exist. BTW, I'm not thinking of cacheing individual directories, but scanning all the directories and building a single qualified_module_name -> pathname mapping. If the cache gets invalidated, all the directories along the path are re-scanned, so a new module will be picked up wherever it is on the path. -- Greg _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
