patch 9.1.0159: Crash in WinClosed after BufUnload closes other windows Commit: https://github.com/vim/vim/commit/b2ec0da080fb24f12a8d6f54bd7318a078ca4e6c Author: zeertzjq <zeertzjq@outlook.com> Date: Sat Mar 9 15:39:27 2024 +0100 patch 9.1.0159: Crash in WinClosed after BufUnload closes other windows Problem: Crash in WinClosed after BufUnload closes other windows Solution: Don't trigger WinClosed if the buffer is NULL (zeertzjq) Now win_close_othertab() doesn't trigger any autocommands if the buffer is NULL, so remove the autocmd blocking above (which was added not long ago in patch v9.0.0550) for consistency. Also remove an unreachable close_last_window_tabpage() above: - It is only reached if only_one_window() returns TRUE and last_window() returns FALSE. - If only_one_window() returns TRUE, there is only one tabpage. - If there is only one tabpage and last_window() returns FALSE, the one_window() in last_window() must return FALSE, and the ONE_WINDOW in close_last_window_tabpage() must also be FALSE. - So close_last_window_tabpage() doesn't do anything and returns FALSE. Then the curtab != prev_curtab check also doesn't make much sense, and the only_one_window() can be replaced with a check for popup and a call to last_window() since this is a stricter check than only_one_window(). closes: #14166 Signed-off-by: zeertzjq <zeertzjq@outlook.com> Signed-off-by: Christian Brabandt <cb@256bit.org>
