Feature: patroni api
	We should check that patroni correctly responds to valid and not-valid API requests.

Scenario: check API requests on a stand-alone server
	Given I start postgres0
	And postgres0 is a leader after 10 seconds
	When I issue a GET request to http://127.0.0.1:8008/
	Then I receive a response code 200
	And I receive a response state running
	And I receive a response role master
	When I issue a GET request to http://127.0.0.1:8008/replica
	Then I receive a response code 503
	When I run patronictl.py reinit batman postgres0 --force
	Then I receive a response returncode 0
	And I receive a response output "Failed: reinitialize for member postgres0, status code=503, (I am the leader, can not reinitialize)"
	When I run patronictl.py failover batman --master postgres0 --force
	Then I receive a response returncode 1
	And I receive a response output "Error: No candidates found to failover to"
	When I issue a POST request to http://127.0.0.1:8008/failover with {"leader": "postgres0"}
	Then I receive a response code 500
	And I receive a response text failover is not possible: cluster does not have members except leader
	When I issue an empty POST request to http://127.0.0.1:8008/failover
	Then I receive a response code 400
	When I issue a POST request to http://127.0.0.1:8008/failover with {"foo": "bar"}
	Then I receive a response code 400
	And I receive a response text "No values given for required parameters leader and candidate"

Scenario: check local configuration reload
	Given I issue an empty POST request to http://127.0.0.1:8008/reload
	Then I receive a response code 200
	And I receive a response text nothing changed
	When I add tag new_tag new_value to postgres0 config
	And I issue an empty POST request to http://127.0.0.1:8008/reload
	Then I receive a response code 202

Scenario: check dynamic configuration change via DCS
	Given I issue a PATCH request to http://127.0.0.1:8008/config with {"ttl": 20, "loop_wait": 1, "postgresql": {"parameters": {"max_connections": 101}}}
	Then I receive a response code 200
	And I receive a response loop_wait 1
	And Response on GET http://127.0.0.1:8008/patroni contains pending_restart after 11 seconds
	When I issue a GET request to http://127.0.0.1:8008/config
	Then I receive a response code 200
	And I receive a response loop_wait 1
	When I issue a GET request to http://127.0.0.1:8008/patroni
	Then I receive a response code 200
	And I receive a response tags {'tag': 'new_value'}

Scenario: check API requests for the primary-replica pair
	Given I start postgres1
	And replication works from postgres0 to postgres1 after 20 seconds
	When I issue a GET request to http://127.0.0.1:8009/replica
	Then I receive a response code 200
	And I receive a response state running
	And I receive a response role replica
	When I run patronictl.py reinit batman postgres1 --force
	Then I receive a response returncode 0
	And I receive a response output "Success: reinitialize for member postgres1"
	When I run patronictl.py restart batman postgres0 --force
	Then I receive a response returncode 0
	And I receive a response output "Success: restart on member postgres0"
	And postgres0 role is the primary after 5 seconds
	When I sleep for 10 seconds
	Then postgres1 role is the secondary after 15 seconds

Scenario: check the failover via the API
	Given I run patronictl.py failover batman --master postgres0 --candidate postgres1 --force
	Then I receive a response returncode 0
	And postgres1 is a leader after 5 seconds
	And postgres1 role is the primary after 5 seconds
	And postgres0 role is the secondary after 10 seconds
	And replication works from postgres1 to postgres0 after 20 seconds

Scenario: check the scheduled failover
	Given I issue a scheduled failover from postgres1 to postgres0 in 1 seconds
	Then I receive a response returncode 0
	And postgres0 is a leader after 20 seconds
	And postgres0 role is the primary after 5 seconds
	And postgres1 role is the secondary after 10 seconds
	And replication works from postgres0 to postgres1 after 25 seconds

Scenario: check the scheduled restart
	Given I issue a PATCH request to http://127.0.0.1:8008/config with {"postgresql": {"parameters": {"superuser_reserved_connections": "6"}}}
	Then I receive a response code 200
		And Response on GET http://127.0.0.1:8008/patroni contains pending_restart after 5 seconds
	Given I issue a scheduled restart at http://127.0.0.1:8008 in 1 seconds with {"role": "replica"}
	Then I receive a response code 202
		And I sleep for 10 seconds
		And Response on GET http://127.0.0.1:8008/patroni contains pending_restart after 10 seconds
	Given I issue a scheduled restart at http://127.0.0.1:8008 in 1 seconds with {"restart_pending": "True"}
	Then I receive a response code 202
		And Response on GET http://127.0.0.1:8008/patroni does not contain pending_restart after 10 seconds
