[PATCH 10/15] t5408: expect client-side error for duplicate destinations

From
Jon Simons <jon@jonsimons.org>
Date
Oct 9, 2026, 19:29 UTC
Message-ID
<20261009192953.81794-11-jon@jonsimons.org>
In-Reply-To
<20261009192953.81794-1-jon@jonsimons.org>

Update the error message expectation for the existing t5408 tests that use send-pack to transmit duplicate updates to an empty remote, and toggle them test_expect_failure.

The tests previously asserted the server-side rejection "multiple updates for ref '<dst>' not allowed".

The next commit rejects these pushes on the client-side such that send-pack fails earlier with "dst ref <dst> receives from more than one src", and never reaches the server. The tests are toggled to test_expect_success then.

While here, change the test descriptions to note that they are no longer asserting anything about the order of partial ref updates.

Also included is a fix for a missing "2>err" in the '--stdin refs come after cmdline' test.
