patch 9.1.0047: issues with temp curwin/buf while cmdwin is open Commit: https://github.com/vim/vim/commit/988f74311c26ea9917e84fbae608de226dba7e5f Author: Sean Dewar <seandewar@users.noreply.github.com> Date: Wed Aug 16 14:17:36 2023 +0100 patch 9.1.0047: issues with temp curwin/buf while cmdwin is open Problem: Things that temporarily change/restore curwin/buf (e.g: win_execute, some autocmds) may break assumptions that curwin/buf is the cmdwin when "cmdwin_type != 0", causing issues. Solution: Expose the cmdwin's real win/buf and check that instead. Also try to ensure these variables are NULL if "cmdwin_type == 0", allowing them to be used directly in most cases without checking cmdwin_type. (Sean Dewar) Alternatively, we could ban win_execute in the cmdwin and audit all places that temporarily change/restore curwin/buf, but I didn't notice any problems arising from allowing this (standard cmdwin restrictions still apply, so things that may actually break the cmdwin are still forbidden). closes: #12819 Signed-off-by: Sean Dewar <seandewar@users.noreply.github.com> Signed-off-by: Christian Brabandt <cb@256bit.org>
