Re: [Tarantool-patches] [PATCH 0/8] wait for lsn and confirm

[Vladislav Shpilevoy <v.shpilevoy@tarantool.org>]

I've got an assertion fail on this test:

Instance 1:

box.cfg{
    listen = 3313,
    replication = {'localhost:3313', 'localhost:3314'},
    replication_timeout = 20,
    replication_synchro_quorum = 2,
    replication_synchro_timeout = 100,
}
box.schema.user.grant('guest', 'super')
s = box.schema.create_space('test', {is_sync = true})
pk = s:create_index('pk')
s:replace{1}


Instance 2:

box.cfg{
    listen = 3314,
    replication = {'localhost:3313', 'localhost:3314'},
    replication_timeout = 20,
    replication_synchro_quorum = 2,
    replication_synchro_timeout = 100,
}
box.schema.user.grant('guest', 'super')

The first instance crashes like this:

Second instance has replica_id 1.
