Subject: [tarantool-patches] [PATCH] tarantoolctl: return an error on enter to a dead socket.
Date: Mon, 16 Jul 2018 11:26:55 +0300	[thread overview]
Message-ID: <20180716082655.42311-1-sergepetrenko@tarantool.org> (raw)

Tarantoolctl enter didn't check whether connection to a socket was established
if a socket file existed. It just executed a local console.
Fix this by adding a check and an error, also add a test case.

Closes #3364
