Subject: [PATCH v4 3/7] update-ref: add support for 'symref-verify' command
Date: Fri, 26 Apr 2024 17:24:45 +0200	[thread overview]
Message-ID: <20240426152449.228860-4-knayak@gitlab.com> (raw)
In-Reply-To: <20240426152449.228860-1-knayak@gitlab.com>

From: Karthik Nayak <karthik.188@gmail.com>

In the previous commits, we added the required base for adding symref
commands to the '--stdin' mode provided by 'git-update-ref(1)'. Using
them, add a new 'symref-verify' command to verify symrefs.

The 'symref-verify' command allows users to verify if a provided <ref>
contains the provided <old-target> without changing the <ref>. If
<old-target> is not provided, the command will verify that the <ref>
doesn't exist. Since we're checking for symbolic refs, this command will
only work with the 'no-deref' mode. This is because any dereferenced
symbolic ref will point to an object and not a ref and the regular
'verify' command can be used in such situations.

Add and use `ref_update_is_null_new_value`, a helper function which is
used to check if there is a new_value in a reference update. The new
value could either be a symref target `new_target` or a OID `new_oid`.
We also add tests to test the command in both the regular stdin mode and
also with the '-z' flag.

We also disable the reference-transaction hook for symref-updates which
will be tackled in its own commit.

Add required tests for symref support in 'verify' while also adding
reflog checks for the pre-existing 'verify' tests.
