From cdef6255095251500cc7d08d304072e1e2fa0bbd Mon Sep 17 00:00:00 2001 From: Jonatan Holmgren Date: Thu, 26 Feb 2026 21:53:28 +0100 Subject: [PATCH] git, help: fix memory leaks in alias listing The list_aliases() function sets the util pointer of each list item to a heap-allocated copy of the alias command value. Two callers failed to free these util pointers: - list_cmds() in git.c collects a string list with STRING_LIST_INIT_DUP and clears it with string_list_clear(&list, 0), which frees the duplicated strings (strdup_strings=1) but not the util pointers. Pass free_util=1 to free them. - list_cmds_by_config() in help.c calls string_list_sort_u(list, 0) to deduplicate the list before processing completion.commands overrides. When duplicate entries are removed, the util pointer of each discarded item is leaked because free_util=0. Pass free_util=1 to free them.
