Alexander Kukushkin cd5e589620 Revert previous commit (restore sigchld_handler) 2015-05-28 13:04:21 +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 01e3beff1c Merge pull request #2 from CyberDem0n/restapi 
Restapi
 2015-05-27 18:31:42 +02:00
Alexander Kukushkin bdc4374ae3 connect address for rest api could be different from listen address 2015-05-27 14:51:41 +02:00
Alexander Kukushkin 5a817fad0d Store in etcd endpoint of restapi 
In order to have backward compatibility connection url of restapi is
passed as application_name parameter in connection url of database.
Value in etcd will look like:
postgres://user:passwd@host:5432/postgres?application_name=http://host:8080/governor
Sure, this is a hack, but I guess it worth it.

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

is_healthiest_node takes into account that one of the nodes could be
still a master
