From 54c8a7c379fc37a847b8a5ec5c419eae171322e1 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=C3=86var=20Arnfj=C3=B6r=C3=B0=20Bjarmason?= Date: Thu, 14 Apr 2022 07:56:40 +0200 Subject: revisions API: add a TODO for diff_free(&revs->diffopt) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add a TODO comment indicating that we should release "diffopt" in release_revisions(). In a preceding commit we started releasing the "pruning" member of the same type, but handling "diffopt" will require us to untangle the "no_free" conditions I added in e900d494dcf (diff: add an API for deferred freeing, 2021-02-11). Let's leave a TODO comment to that effect, and so that we don't forget refactor code that was changed to use release_revisions() in earlier commits to stop using the "diffopt" member after a call to release_revisions(). This works currently, but would become a logic error as soon as we started freeing "diffopt". Doing that change now doesn't harm anything, and future-proofs us against a later change to release_revisions().
