__DATA__

=== TEST 1: sanity
--- config
    location /t {
        content_by_lua_block {
            local encode_json = require "lib.json_sort" .encode
            local config = require("apisix.core").config.local_conf()

            ngx.say("node_listen: ", config.apisix.node_listen)
            ngx.say("stream_proxy: ", encode_json(config.apisix.stream_proxy))
            ngx.say("admin_key: ", encode_json(config.apisix.admin_key))
        }
    }
--- request
GET /t
--- response_body
node_listen: 1984
stream_proxy: {"tcp":[9100]}
admin_key: null



=== TEST 2: wrong type: expect: number, but got: string
--- yaml_config
apisix:
  node_listen: xxxx
--- must_die
--- error_log
failed to parse yaml config: failed to merge, path[apisix->node_listen] expect: number, but got: string



=== TEST 3: use `null` means delete
--- yaml_config
apisix:
  admin_key: null
--- config
  location /t {
    content_by_lua_block {
        local encode_json = require "lib.json_sort" .encode
        local config = require("apisix.core").config.local_conf()

        ngx.say("admin_key: ", encode_json(config.apisix.admin_key))
    }
}
--- request
GET /t
--- response_body
admin_key: null



=== TEST 4: use `~` means delete
--- yaml_config
apisix:
  admin_key: ~
--- config
  location /t {
    content_by_lua_block {
        local encode_json = require "lib.json_sort" .encode
        local config = require("apisix.core").config.local_conf()
