Subject: [PATCH v10 3/3] t, doc: update tests, reference for "--force-if-includes"
Date: Sat, 3 Oct 2020 17:40:46 +0530 [thread overview]
Message-ID: <20201003121046.60604-4-shrinidhi.kaushik@gmail.com> (raw)
In-Reply-To: <20201003121046.60604-1-shrinidhi.kaushik@gmail.com>
Update test cases for the new option, and document its usage
and update related references.
Update test cases for the new option, and document its usage
and update related references.
- t/t5533-push-cas.sh:
Update test cases for "compare-and-swap" when used along with
"--force-if-includes" helps mitigate overwrites when remote
refs are updated in the background; allows forced updates when
changes from remote are integrated locally.
- Documentation:
Add reference for the new option, configuration setting
("push.useForceIfIncludes") and advise messages.

+This option enables a check that verifies if the tip of the
