René's URL Explorer Experiment

{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"Implement import completion cache","articleBody":"## Steps to reproduce\r\n1. Change current directory to directory containing big sub-tree (ie. system root directory).\r\n2. start bpython executable\r\n3. observe high CPU usage in processor monitor / manager.\r\n\r\n## Affected versions\r\n0.19 and above\r\n\r\n## Detailed Description\r\nThis problem started after 1a674f00311523558d627eb333409afc6cfe0865. It seems that new `find modules` implementation based on `importlib.machinery.FileFinder` is much slower than previous one.\r\n\r\nShould bpython traverse whole sub-tree on each startup? Quite often I do start it from my home directory and traversing all it's contents including mounted remote filesystems seems wasteful.","author":{"url":"https://github.com/xvuko","@type":"Person","name":"xvuko"},"datePublished":"2020-11-09T15:58:26.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/861/bpython/issues/861"}
