Subject: [PATCH v6 07/19] index-helper: add --detach
Date: Wed, 27 Apr 2016 16:04:29 -0400 [thread overview]
Message-ID: <1461787481-877-8-git-send-email-dturner@twopensource.com> (raw)
In-Reply-To: <1461787481-877-1-git-send-email-dturner@twopensource.com>
From: Nguyễn Thái Ngọc Duy <pclouds@gmail.com>
We detach after creating and opening the socket, because otherwise
we might return control to the shell before index-helper is ready to
accept commands. This might lead to flaky tests.
