Subject: [PATCH 0/2] Fix shallow clone with ref-in-want enabled
Date: Wed, 24 Dec 2025 01:35:02 +0100	[thread overview]
Message-ID: <20251224003504.52660-1-mats.dodd12@gmail.com> (raw)

From: Mats-Dodd <mats.dodd12@gmail•com>

The ref-in-want feature (uploadpack.allowRefInWant) has been broken with
shallow clones since it was introduced in 516e2b76bdc (upload-pack:
implement ref-in-want, 2018-06-27). When enabled, shallow clones fail
with:

    fatal: expected 'packfile', received 'shallow-info'

The server sends protocol v2 sections in the wrong order, violating the
specification in Documentation/gitprotocol-v2.adoc and client expectations
in fetch-pack.c.

This series:
1. Fixes the section ordering in upload-pack.c (swap two lines)
2. Adds a regression test for shallow clone + ref-in-want

Mats-Dodd (2):
  upload-pack: send shallow-info before wanted-refs in protocol v2
  t5703: add test for shallow fetch with ref-in-want
