Subject: [PATCH 1/2] remote: move static variables into struct
Date: Thu, 07 Oct 2021 19:07:14 +0000 [thread overview]
Message-ID: <f7639a20fcd437d5f50665b5c6f5318c1245b9b5.1633633635.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.1103.git.git.1633633635.gitgitgadget@gmail.com>
From: Glen Choo <chooglen@google.com>
remote.c only works with the_repository because it stores its state as
static variables. To support non-the_repository, we can use a
per-repository struct for the remotes subsystem.
Prepare for this change by moving the static variables of remote.c into
a static struct remote_state.
This introduces no behavioral or API changes.
