From: David Turner Date: Sun, 26 Jun 2016 04:14:11 GMT Subject: [PATCH v13 07/20] index-helper: add --detach Message-ID: <1466914464-10358-7-git-send-email-novalis@novalis.org> In-Reply-To: <1466914464-10358-1-git-send-email-novalis@novalis.org> From: Nguyễn Thái Ngọc Duy 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.
