Hi catalog-sig,
When we initially implemented file upload to PyPI it was our intention
that the file be immutable once uploaded. The goal was to make things
significantly simpler for end users - there would only ever be one
file with a given name. If the content changed then so must the name
(typically by creating a new release version.)
After the upload facility was put in place we also added the ability
to delete files uploaded to pypi. This created a loophole: if a
package owner knew how to they could delete the file and re-upload,
thus circumventing the replacement protection.
I'm considering closing this loophole by retaining a record of the
uploaded file (though not the contents) so that future uploads with
the same name wouldn't be allowed. I understand that this is how the
ruby gem archive handles deletion of files.
Your thoughts?
Richard
