From 1c890016a147536e4a6faa5664eedd8765a01b32 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Mon, 17 Aug 2020 17:33:13 -0400 Subject: [PATCH] config: fix leak in git_config_get_expiry_in_days() We use git_config_get_string() to retrieve the expiry value in a newly allocated string. But after parsing it, we never free it, leaking the memory. We could fix this with a free() obviously, but there's an even better solution: we can use the non-allocating "tmp" variant of the function; we only need it to be valid for the lifetime of our parse function.
