Oleksii Kliukin fd884a53a9 Multiple small fixes: 
- Do delete trigger file in the patroni itself.
- Fix the typo in the datadir member.
- Add #! at the top of the python script.
 2015-08-03 15:51:40 +02:00
Oleksii Kliukin 2089a123c2 fix line too long warning. 2015-08-03 11:48:02 +02:00
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 5171964758 Merge branch 'master' into feature/callbacks 2015-07-27 16:19:03 +02:00
Oleksii Kliukin 115ba1d9ae Make sure postgresql.stop also return True if pg_ctl stop returned 0. 2015-07-27 11:23:08 +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 dac3d7997f Change a typo. 2015-07-24 10:47:26 +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.
 2015-07-17 15:39:34 +02:00
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.

Oleksii Kliukin d8aa1ff849 fix a typo. 2015-07-14 09:22:49 +02:00
Oleksii Kliukin f734272f3f Process the command paths relative to the patroni dir correctly, fix the error of not supplying a callback action to the actual command. 2015-07-13 11:45:25 +02:00
Oleksii Kliukin c0cc590938 Remove usage of AWS.py from Patroni 
Functionality provided by that module will be achieved via callbacks.
- fix a typo in aws.py
- fix some mixups of old code and new callbacks in postgresql.py

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.
