From 1ca57bea4a8a4637c4e7d2a2f46677acc4795d81 Mon Sep 17 00:00:00 2001 From: Patrick Steinhardt Date: Wed, 14 Aug 2024 08:52:17 +0200 Subject: builtin/rebase: fix leaking `commit.gpgsign` value In `get_replay_opts()`, we override the `gpg_sign` field that already got populated by `sequencer_init_config()` in case the user has "commit.gpgsign" set in their config. This creates a memory leak because we overwrite the previously assigned value, which may have already pointed to an allocated string. Let's plug the memory leak by freeing the value before we overwrite it.

Restructure the function to have a common exit path such that we can easily clean up the list and thus plug this memory leak.
