The first is a +crash that results if the initial prompt contains more than 256 wrapped +lines. The second is a fix to the redisplay code when the first several +characters of the prompt string are identical, but the prompt has changed +and needs to be redrawn. If these first few characters are part of an escape +sequence, the entire sequence needs to be redrawn. + +Patch (apply with `patch -p0'): + +*** ../readline-8.3-patched/display.c Fri May 22 14:55:01 2026 +--- display.c Fri Jun 26 11:08:53 2026 +*************** +*** 1025,1028 **** +--- 1025,1029 ---- + { + temp = local_prompt_newlines[newlines+1]; ++ CHECK_INV_LBREAKS (); + inv_lbreaks[++newlines] = temp; + } +*************** +*** 2262,2270 **** + nd = nfd - new; /* nd, od are buffer indexes */ + if (current_line == 0 && !_rl_horizontal_scroll_mode && +! _rl_term_cr && lendiff > prompt_visible_length && _rl_last_c_pos > 0 && + (((od > 0 || nd > 0) && (od <= prompt_last_invisible || nd <= prompt_last_invisible)) || + ((od >= lendiff) && _rl_last_c_pos < PROMPT_ENDING_INDEX))) + { +! _rl_cr (); + if (modmark) + _rl_output_some_chars ("*", 1); +--- 2266,2275 ---- + nd = nfd - new; /* nd, od are buffer indexes */ + if (current_line == 0 && !_rl_horizontal_scroll_mode && +! _rl_term_cr && lendiff > prompt_visible_length && _rl_last_c_pos >= 0 && + (((od > 0 || nd > 0) && (od <= prompt_last_invisible || nd <= prompt_last_invisible)) || + ((od >= lendiff) && _rl_last_c_pos < PROMPT_ENDING_INDEX))) + { +! if (_rl_last_c_pos > 0) +! _rl_cr (); + if (modmark) + _rl_output_some_chars ("*", 1); +*** ../readline-8.3/patchlevel 2013-11-15 08:11:11.000000000 -0500 +--- patchlevel 2024-03-21 08:28:40.000000000 -0400 +*************** +*** 1,3 **** + # Do not edit -- exists only for use by patch + +! 4 +--- 1,3 ---- + # Do not edit -- exists only for use by patch + +! 5 |
