dmypy receives the list of updated files via
--update
flag. If this list contains bothfoo.py
andfoo.pyi
, the order matters. It seems to process the first file in the list first. But if we have a.pyi
file, we want this to be processed first since this one contains the typing information.Let's reverse sort the list of updated files by the extension. This should be a simple enough fix to resolve this.
Though there might be some edge cases where the list of files to update contains just pyi files, but we might need to recheck the equivalent py files even if not explicitly updated.
