Bug 263392

Per https://packaging.python.org/en/latest/specifications/binary-distribution-format/#installing-a-wheel-distribution-1-0-py32-none-any-whl, we should just be unpacking the archive. However, currently, for each file in the wheel, we: for directory in to_be_moved: shutil.rmtree(os.path.join(AutoInstall.directory, directory), ignore_errors=True) shutil.move(os.path.join(temp_location, directory), AutoInstall.directory) (https://github.com/WebKit/WebKit/blob/723eb83c4fdb24e0d50c664452328dc6188ca7dd/Tools/Scripts/libraries/webkitcorepy/webkitcorepy/autoinstall.py#L400-L402) This means that when we unpack autobahn (20.7.1), which contains: gsnedders@gsnedders-marsha ~ % grep '^twisted' '/var/folders/qk/hmjj9_lx2cg3_4v3vx3y7y_w0000gn/T/autobahn-77395/autobahn-20.7.1.dist-info/RECORD' twisted/plugins/autobahn_endpoints.py,sha256=6XClHTi8llFb6p6iKE3npCYGlNwJZwCcs3fSc2knE0c,6349 twisted/plugins/autobahn_twistd.py,sha256=9mccXpFlai3XpoYHAtxAynedzogaLb6XM7-Qb9IF5yQ,1566 …we end up deleting all of twisted, rather than just unpacking these files into the twisted package. (This is the cause of some of the failures on bug 263119.)
