Subject: [PATCH 24/24] t/helper/test-repository: celebrate independence from the_repository
Date: Tue, 30 Oct 2018 15:08:17 -0700 [thread overview]
Message-ID: <20181030220817.61691-25-sbeller@google.com> (raw)
In-Reply-To: <20181030220817.61691-1-sbeller@google.com>
dade47c06c (commit-graph: add repo arg to graph readers, 2018-07-11)
brought more independence from the_repository to the commit graph, however
it was not completely independent of the_repository, as the previous
patches show.
To ensure we're not accessing the_repository by accident, we'd ideally
assign NULL to the_repository to trigger a segfault on access.
We currently have a temporary hack in cache.h, which relies on
the_hash_algo (which is a short form of the_repository->hash_algo) to
be set, so we cannot do that. The next best thing is to set all fields of
the_repository to 0, so any accidental access is more likely to be found.
