-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)
