From 0a4d31537d66bd2249adc8d923e2e6829204059e Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=C3=86var=20Arnfj=C3=B6r=C3=B0=20Bjarmason?= Date: Thu, 1 Sep 2022 01:14:12 +0200 Subject: [PATCH] submodule--helper: don't leak {run,capture}_command() cp.dir argument MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fix a memory leak in c51f8f94e5b (submodule--helper: run update procedures from C, 2021-08-24) and 3c3558f0953 (submodule--helper: run update using child process struct, 2022-03-15) by not allocating memory in the first place. The "dir" member of "struct child_process" will not be modified by that API, and it's declared to be "const char *". So let's not needlessly duplicate these strings.
