[PATCH 18/20] config: don't depend on `the_repository` with branch conditions

From
Patrick Steinhardt <ps@pks.im>
Date
Aug 7, 2024, 06:58 UTC
Message-ID
<d8530a300b4cf0f854f2b0d03c79876c11d81116.1723013714.git.ps@pks.im>
In-Reply-To
<cover.1723013714.git.ps@pks.im>

When computing branch "includeIf" conditions we use `the_repository` to obtain the main ref store. We really shouldn't depend on this global repository though, but should instead use the repository that is being passed to us via `struct config_include_data`. Otherwise, when parsing configuration of e.g. submodules, we may end up evaluating the condition the via the wrong refdb.

Fix this.
