[issue42819] readline 8.1 bracketed paste

[FX Coudert]

FX Coudert <fxcoudert at gmail.com> added the comment:

This bug is present in all versions since the 3.6 branch at least, but was only triggered when users' readline settings explicitly enabled bracketed-paste. Previous reports: https://bugs.python.org/issue32019 and https://bugs.python.org/issue39820 Longer discussion (on a more extensive feature request) at https://bugs.python.org/issue38747

The new factor is that readline 8.1 now enables bracketed-paste by default. So the broken behaviour is seen for Python built with the latest readline, with no specific setting.

Python should probably in the long term be improved to handle bracketed-paste, which will make a nicer user experience. But in the short term, it should communication with readline to disable bracketed-paste at runtime, and restore the previous behaviour.
