Subject: [PATCH 5/9] refs: avoid duplicate running of the reference-transaction hook
Date: Fri, 29 Jul 2022 18:12:41 +0800 [thread overview]
Message-ID: <20220729101245.6469-6-worldhello.net@gmail.com> (raw)
In-Reply-To: <20220729101245.6469-1-worldhello.net@gmail.com>
From: Jiang Xin <zhiyou.jx@alibaba-inc.com>
If there are references to be deleted in a transaction, we should remove
each reference from both loose references and the "packed-refs" file.
The "reference-transaction" hook will run twice, once for the primary
ref-store (loose references), and another for the second ref-store (i.e.
packed ref-store).
To avoid duplicate running of the "reference-trancaction" hook, we pass
a special "hook-flags" parameter to initialize the second ref-store.
The "REF_TRANSACTION_RUN_PREPARED_HOOK" bit is preserved for the
transaction of the second ref-store because we may still want to call
command "reference-trancaction prepared" for some pre-checks, such as
terminate unwanted transaction for the "packed-refs" file.
The behavior of the following git commands and five testcases have been
fixed in t1416:
* git cherry-pick
* git rebase
* git revert
* git update-ref -d <ref>
* git update-ref --stdin # delete refs
