From 71c871b48dfaf300ca20e205917db72ab9c6d7b3 Mon Sep 17 00:00:00 2001 From: Patrick Steinhardt Date: Fri, 17 May 2024 10:18:24 +0200 Subject: refs: implement releasing ref storages Ref storages are typically only initialized once for `the_repository` and then never released. Until now we got away with that without causing memory leaks because `the_repository` stays reachable, and because the ref backend is reachable via `the_repository` its memory basically never leaks. This is about to change though because of the upcoming migration logic, which will create a secondary ref storage. In that case, we will either have to release the old or new ref storage to avoid leaks. Implement a new `release` callback and expose it via a new `ref_storage_release()` function.
