READLINE PATCH REPORT ===================== Readline-Release: 7.0 Patch-ID: readline70-001 Bug-Reported-by: Sean Zha Bug-Reference-ID: Bug-Reference-URL: http://lists.gnu.org/archive/html/bug-bash/2016-09/msg00107.html Bug-Description: Readline-7.0 changed the way the history list is initially allocated to reduce the number of reallocations and copies. Users who set the readline history-size variable to a very large number to essentially unlimit the size of the history list will get memory allocation errors Patch (apply with `patch -p0'): *** ../readline-7.0/history.c 2015-12-28 13:50:31.000000000 -0500 --- history.c 2016-09-30 14:28:40.000000000 -0400 *************** *** 58,61 **** --- 58,63 ---- #define DEFAULT_HISTORY_INITIAL_SIZE 502 + #define MAX_HISTORY_INITIAL_SIZE 8192 + /* The number of slots to increase the_history by. */ #define DEFAULT_HISTORY_GROW_SIZE 50 *************** *** 308,312 **** { if (history_stifled && history_max_entries > 0) ! history_size = history_max_entries + 2; else history_size = DEFAULT_HISTORY_INITIAL_SIZE; --- 310,316 ---- { if (history_stifled && history_max_entries > 0) ! history_size = (history_max_entries > MAX_HISTORY_INITIAL_SIZE) ! ?
