In all other cases pick the first one.

Alexander Kukushkin adcc7ac256 Try to avoid "double" promotion. 
Also check presence of trigger_file on master after promotion when
pg_is_in_recovery() = false and if it is there - remove it.
Plus check presence of trigger_file on a new slave (after running
pg_basebackup) and if it is there - also remove it.

Alexander Kukushkin aa486194ae Wrap time.sleep into wrapper function 
In case if it was interrupted by SIGCHLD but scheduled awake time is not
reached it will continue sleeping. For all other signals behaviuor is
not changed.

Feike Steenbergen 119c56e5d3 Merge pull request #18 from CyberDem0n/master 
Set handler of SIGCHLD to SIG_IGN
 2015-05-28 12:43:05 +02:00
Alexander Kukushkin f76f77e964 Ignore SIGCHLD instead of processing it. 
This way time.sleep wont be interrupted when some external process is
finished and terminated childs would be reaped automatically.

Alexander Kukushkin ce267d9f1e query method will retry only in case of communication error 2015-05-24 09:01:23 +02:00
Alexander Kukushkin d202f72a42 Added simple web server which shows current state of postgres 
Server always returns json which contains some status of postgres:
* instance type: master/slave
* xlog location for master
* xlog received_location, replayed_location
This server could be used by haproxy
GET / returns 200 if there is postgres master behind governor.
GET /slave returns 200 is there is postgres slave behind governor
In all other cases it returns 503
Currently server always listening on 0.0.0.0:8080, but it should be
configurable. In the next versions this rest api could also report some
status of etcd and could be used by is_healthiest_node method
 2015-05-23 20:29:51 +02:00
Alexander Kukushkin f53c369c69 Connect timeout 5 seconds for psycopg2 
Refactored query and is_healthiest_node methods
query method wont retry more then 3 times if OperationalError raised
is_healthiest_node takes into account that one of the nodes could be
still a master
