Oleksii Kliukin da132ca1fc Do not rely on env vars for superuser role name.
Environment variables may not be set in Docker.
Instead, obtain the superuser role from the database.

Oleksii Kliukin a5f2ab6f88 Better SIGCHLD handling, use correct user name.
- Defer SIGCHLD processing until the later stage in order to allow
  subprocess to run its own reaping of children and return the correct
  exit code from the process called.

- When changing the password at startup, do not assume the user postgres.

Oleksii Kliukin 7f2dcc0a95 Move replica creation code into a separte file. So far, only the class that makes replicas with pg_basebackup is called. 2015-08-03 11:44:11 +02:00
Oleksii Kliukin a0fdd6398f Cosmetic changes: avoid magic strings in action names, name the parameter passed to the callback 'scope' for consistency. 2015-07-30 10:17:17 +02:00

Oleksii Kliukin 201f9bf4b2 Make sure role check during callbacks does not accidentially modify the cluster state (is_promoted flag or trigger file). 2015-07-27 11:08:19 +02:00

Oleksii Kliukin c9c678fb5b Pass scope, the cluster name, instead of the name, which is the instance name, to the callback. 2015-07-23 16:16:22 +02:00
Oleksii Kliukin e9934be9aa Do not terminate on callback failure.
Show the error if a callback command fails and move on.
Set the executable bit for the aws callback.
2015-07-17 17:26:28 +02:00
Oleksii Kliukin a11d94aff5 Pass text names of cluster roles to the script.
Seems better than passing a bool flag and
converting it from/to string.

Oleksii Kliukin 33b5e1b22e Make sure is_leader is False does not trigger the leader re-check. 2015-07-17 15:22:21 +02:00
Oleksii Kliukin 11004f8c48 Be more robust on callbacks when cluster is down.
For 'on_stop' or 'on_restart' callbacks we cannot
call is_leader, because the cluster would be stopped.

Instead, call is_leader before running a callback.
In addition, make the call_nowait more robust by handling
the exceptions related to the DB cluster unavailability.
