Subject: [PATCH v3 0/1] Fix empty SHA-256 clones with v0 and v1
Date: Wed, 17 May 2023 19:24:42 +0000 [thread overview]
Message-ID: <20230517192443.1149190-1-sandals@crustytoothpaste.net> (raw)
In-Reply-To: <ZEmMUFR7AJn+v7jV@tapette.crustytoothpaste.net>
We recently fixed empty clones with SHA-256 over protocol v2 by
honouring the hash algorithm specified even when no refs are present.
However, in doing so, we made it impossible to set up a v0 or v1
repository by cloning from an empty SHA-256 repository. In doing so, we
also broke the Git LFS testsuite for SHA-256 repositories.
This series introduces the dummy `capabilities^{}` entry for fetches and
clones from an empty repository for v0 and v1, just as we do for clones.
This is already supported by older versions of Git, as well as libgit2,
dulwich, and JGit.
Changes since v2:
* Move advertisement of fake capabilities ref to a separate function to
avoid an extra strcmp.
Changes since v1:
* Drop patch to honour GIT_DEFAULT_HASH
* Support all requests, not just HTTP.
* Add more tests.
* Fix NULL pointer dereference.
