From 3218cb753f5a2a49808bf07f039051e7b79b8f44 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=C3=86var=20Arnfj=C3=B6r=C3=B0=20Bjarmason?= Date: Sun, 12 Sep 2021 02:24:40 +0200 Subject: [PATCH] gc: remove unused launchctl_get_uid() call MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When the launchctl_boot_plist() function was added in a16eb6b1ff3 (maintenance: skip bootout/bootstrap when plist is registered, 2021-08-24), an unused call to launchctl_get_uid() was added along with it. That call appears to have been copy/pasted from launchctl_boot_plist(). Since we can remove that, we can also get rid of the "result" variable, whose only purpose was allow for the free() between its assignment and the return. That pattern also appears to have been copy/pasted from launchctl_boot_plist(). As the patch shows the returned value from launchctl_get_uid() wasn't used at all in this function. The launchctl_get_uid() function itself just calls xstrfmt() and getuid(), neither of which have any subtle global side-effects, so this removal is safe.
