net.box connection not re-established after a disconnect

[viciious]

t1.lua

box.cfg{listen=12123}

function hello() print('hello') end

box.schema.func.create('hello', {if_not_exists = true})
box.schema.user.grant('guest', 'execute', 'function', 'hello', {if_not_exists = true})

t2.lua

local net_box = require('net.box')
local fiber = require('fiber')

box.cfg{}

cf = fiber.create(function()
    local conn = net_box.new('127.0.0.1:12123')
    while true do
        conn:timeout(10):call('hello')
        fiber.sleep(1)
    end
end)

mon = fiber.create(function()
    while true do
        print(cf:status())
        fiber.sleep(1)
    end
end)

Steps to reproduce:

• start the first tarantool instance: tarantool t1.lua
• start the second tarantool instance: tarantool t2.lua
• watch the first and the second instances print "hello" and "suspended" at 1s intervals respectively
• restart the first instance
• see the 'cf' fiber die in the second instance:

The observed behavior doesn't match the documentation on net.box.new():

net_box.new(URI[, {option[s]}])
Create a new connection. The connection is established on demand, at the time of the first request. It is re-established automatically after a disconnect.

Please pass reconnect_after=<timeout> to net_box.new.

We will improve the documentation (tarantool/doc#33)

[viciious]

Is the new option only available on the development branch?

Available in 1.6 as well.
