Subject: [PATCH 11/24] bundle-uri: create "key=value" line parsing
Date: Fri, 20 May 2022 18:40:29 +0000 [thread overview]
Message-ID: <4e0286f8e20da83c3d111e99eb9f6d9d764a84e6.1653072042.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.1234.git.1653072042.gitgitgadget@gmail.com>
From: =?UTF-8?q?=C3=86var=20Arnfj=C3=B6r=C3=B0=20Bjarmason?=
<avarab@gmail.com>
When advertising a bundle list over Git's protocol v2, we will use
packet lines. Each line will be of the form "key=value" representing a
bundle list. Connect the API necessary for Git's transport to the
key-value pair parsing created in the previous change.
