Subject: [PATCH v4 4/5] run-command: refactor subprocess env preparation
Date: Thu, 17 Jun 2021 10:13:25 -0700 [thread overview]
Message-ID: <1778cbf878b992c9e00e0d0f54301426467977ab.1623949899.git.jonathantanmy@google.com> (raw)
In-Reply-To: <cover.1623949899.git.jonathantanmy@google.com>
submodule.c has functionality that prepares the environment for running
a subprocess in a new repo. The lazy-fetching code (used in partial
clones) will need this in a subsequent commit, so move it to a more
central location.
