Subject: [PATCH 2/5] run-command: Call get_next_task with a clean child process.
Date: Mon, 19 Oct 2015 11:24:43 -0700	[thread overview]
Message-ID: <1445279086-31066-3-git-send-email-sbeller@google.com> (raw)
In-Reply-To: <1445279086-31066-1-git-send-email-sbeller@google.com>

If the `get_next_task` did not explicitly called child_process_init
and only filled in some fields, there may have been some stale data
in the child process. This is hard to debug and also adds a review
burden for each new user of that API. To improve the situation, we
pass only cleanly initialized child structs to the get_next_task.
