Subject: [PATCH v3 2/5] test: errinj for pause relay_send
Date: Thu,  6 Dec 2018 16:38:49 +0300	[thread overview]
Message-ID: <20181206133852.75633-3-sergw@tarantool.org> (raw)
In-Reply-To: <20181206133852.75633-1-sergw@tarantool.org>

Instead of using timeout we need just pause `relay_send`. Can't rely
on timeout because of various system load in parallel mode. Add new
errinj which checks boolean in loop and until it is not `True` do not
pass the method `relay_send` to the next statement.

To check the read-only mode, need to make a modification of tuple. It
is enough to call `replace` method. Instead of `delete` and then
useless verification that we have not delete tuple by using `get`
method.

And lookup the xlog files in loop with a little sleep, until the file
count is not as expected.

Update box/errinj.result because new errinj was added.

Part of #2436, #3232
