patch 9.1.0264: libgpm may delete some signal handlers Commit: https://github.com/vim/vim/commit/cc59d62215b075c715294ad24a41bfd091cb8d48 Author: Julio B <julio.bacel@gmail.com> Date: Thu Apr 4 21:55:10 2024 +0200 patch 9.1.0264: libgpm may delete some signal handlers Problem: libgpm may delete some signal handlers Solution: restore these signal handlers after calling gpm (Julio B) When 'mouse' is set, vim is trying to detect mouse support on startup. Eventually, vim resorts to using libgpm as the final method of mouse detection. This library may delete some signals handlers that were initially set up by vim. This is how: - mch_setmouse() calls gpm_open() - Gpm_Open is executed, which returns early on line 210 [1] - Keep in mind that lines 353-373 [2] are skipped, so gpm_saved_suspend_hook and gpm_saved_winch_hook are empty - Finally, Gpm_Close is called, which will reset [3] SIGWINCH and SIGTSTP to an empty sigaction.
