-Subject: [PATCH] [3.14] gh-153030: Fix quadratic complexity in incremental
- parsing in HTMLParser (GH-153031) (GH-153039)
-
-When an unterminated construct (e.g. a tag or comment) spanned many
-feed() calls, rescanning the growing buffer and concatenating new data
-onto it were both quadratic. New data is now accumulated in a list and
-only joined and parsed once enough has piled up.
-(cherry picked from commit bcf98ddbc40ec9b3ee87da0124a5660b19b7e606)
