-Subject: [PATCH] [3.11] gh-98433: Fix quadratic time idna decoding. (GH-99092)
- (GH-99222)
-
-There was an unnecessary quadratic loop in idna decoding. This restores
-the behavior to linear.
-
-(cherry picked from commit d315722564927c7202dd6e111dc79eaf14240b0d)
-
-(cherry picked from commit a6f6c3a3d6f2b580f2d87885c9b8a9350ad7bf15)

-+The IDNA codec decoder used on DNS hostnames by :mod:`socket` or :mod:`asyncio`
