Alexander Kukushkin 01da5266a0 Give time for running healh-checks when promoting replica 2016-04-13 13:32:39 +02:00

Alexander Kukushkin b4e86f0809 Make it possible to schedule failover in less then 10 seconds 
But only when API request was posted to the leader

Alexander Kukushkin 94331fde6d Do not try to fetch xlog_location when async_executor is busy 2016-04-13 13:32:39 +02:00
Alexander Kukushkin ff41818a84 Make unit-tests output less verbose 
It will capture output to stdout and stderr and print it when test is
failed. Please set LOGLEVEL env variable to INFO or DEBUG if you want
to see everything (as it was before).

Alexander Kukushkin 15d30a2d35 Try to stabilize acceptance tests 2016-04-13 13:32:39 +02:00
Alexander Kukushkin f8bf1bb0ab Disable sudo, reshuffle travis tasks and introduce caching 
Without sudo travis is executing build tasks using docker and waiting
time in this case is really small, usually not longer then 10 seconds.

postgresql-9.5 is installed via addons.apt.packages (without sudo)
But ports 5432 and 5433 are busy. So I had to ajust environment.py to
assign port from higher diapason.

And a few words about build tasks:
First task is used for executing unit tests for all different python versions
The second one is used for executing acceptance tests against etcd
The third one is used for executing acceptance tests against zookeeper
acceptance tests are executed with python2.7 and python3.5

In addition that I've introduced caching of python virtual environment.
It really helps to reduce time needed to install python modules.

Alexander Kukushkin 24a2ea6cef Refactor acceptance tests to make them work against ZooKeeper 
and make it easier to implement controllers for new DCS, i.e. consul

Alexander Kukushkin db5999a639 Correct implementation of 'clonefrom' feature 
According to https://github.com/zalando/patroni/issues/48 'clonefrom'
tag should be boolean and it should be used to mark node as a suitable
for creation of a new replica from. If there are more then one such node
in the cluster (with tag clonefrom=true), one of them will be chosed
randomly.

Alexander Kukushkin 9c41ce9f1c We should run checkpoint before shutdown all the time except one case 
(when patroni is being shutdown)
 2016-03-24 14:50:34 +01:00
Alexander Kukushkin e6af18f0bb Former leader was not able to reattach to cluster without pg_rewind 
It was shutdown correctly and I expected such 'join' working, but it was
not, because new leader didn't had enough time to catch up with the
master before promote.

Bugfix: In some cases Ha.cluster can be None after calling `get_cluster`
 2016-03-24 12:36:25 +01:00
Alexander Kukushkin 9dc588231f Speed up reattach of former leader to the cluster 
Instead of starting it up in "read-only", it wil wait 2 seconds, to give
a time to somebody to prompte and after it will execute normal `recover`
procedure.
 2016-03-24 12:29:30 +01:00
Alexander Kukushkin 0d3dca56ff In some cases Ha.cluster can be None after calling get_cluster 
Such situation is causing patroni crash. Usually it was happening during
manual failover, after former master has demoted and `reset_cluster`
method has been called. In this case `fetch_cluster` was `False` and
`_load_cluster` method was returning value from `self._cluster`, which
was `None`.

Alexander Kukushkin 0e0c8ed8d7 Implement delete_cluster interface in for all available dcs 
In addition to that rename confusing `Etcd.client` and
`ZooKeeper.client` into `_client`. This attribute is available from
AbstractDCS and people had wrong impression that it provides the same
interface for different DCS implementations, which is obviously not the
case. For Etcd it has type etcd.Client and for ZooKeeper - KazooClient.
