From: Denton Liu Date: Fri, 18 Sep 2020 11:19:04 GMT Subject: [PATCH 3/4] hooks--pre-push.sample: use hash-agnostic null OID Message-ID: <9d6c2951ab0a2c2e92353c238b008538fe6a6327.1600427894.git.liu.denton@gmail.com> In-Reply-To: The pre-push sample hook has the null OID hardcoded as 40 zeros. However, with the introduction of SHA-256 support, this assumption no longer holds true. Replace the hardcoded $z40 with a call to `git rev-parse --null-oid` so the sample hook becomes hash-agnostic.
