Subject: [RFC PATCH 14/22] worktree: allow repository version 1
Date: Mon, 13 Jan 2020 12:47:21 +0000 [thread overview]
Message-ID: <20200113124729.3684846-15-sandals@crustytoothpaste.net> (raw)
In-Reply-To: <20200113124729.3684846-1-sandals@crustytoothpaste.net>
Git supports both repository versions 0 and 1. These formats are
identical except for the presence of extensions. When using an
extension, such as for a different hash algorithm, a check for only
version 0 causes the check to fail. Instead, call
verify_repository_format to verify that we have an appropriate version
and no unknown extensions.
