[3.7] bpo-27657: Revert - Fix urlparse() with numeric paths (GH-661)" by orsenthil · Pull Request #18526 · python/cpython (original) (raw)

This reverts commit 82b5f6b.

The change broke the backwards compatibility of parsing behavior in a patch release of Python (3.7.6). A decision was taken to revert this patch in 3.7.7.

In https://bugs.python.org/issue27657 it was decided that the previous behavior like

urlparse('localhost:8080') ParseResult(scheme='', netloc='', path='localhost:8080', params='', query='', fragment='')

urlparse('undefined:8080') ParseResult(scheme='', netloc='', path='undefined:8080', params='', query='', fragment='')

needs to be preserved in patch releases as number of users rely upon it.

Explicitly mention the releases involved with the revert in NEWS. Adopt the wording suggested by @ned-deily.
