This resolves issue python#105931. Currently the '-s STRIPDIR' option on compileall can lead to some surprising results as it only strips away path components that match, but leaves alone the non-matching ones interspersed in between. For example, with: python -m compileall -s/path/to/another/src /path/to/build/src/file.py The resulting written path will be: build/file.py This fix only strips directories that are a fully matching prefix of the source path. If a stripdir is provided that is not a valid prefix, a warning will be displayed (which can be silenced with '-qq').

I like the simplicity of the solution and I have just one suggestion. I'm not a core developer so we'll need someone to approve and merge this, Cc: @encukou (helped with the original implementation so he has the necessary context).

The original behaviour is clearly wrong.
IMO, we don't need a deprecation period to change it: the filename is essentially debug information.
I don't plan to backport to this to previous versions (at least initially): new warnings/outputs tend to cause trouble for users.
