Fix return value in the should_run_scheduled_action and the comments.
Correct the json composition in the scheduled_restart test.
Fix the delete in case there is no scheduled restart.
Fix the usage of format in the logger output.
Fix the indentation in the evaluate_scheduled_restart.
Fix the condition related to the body_is_optional in the do_POST_restart.
Fix a few typos in the error messages.
Fix the _read_json_content
Make the scheduled restart unit-tests a bit less ugly
The scheduled restart data structures are now independent of those
used by the normal restarts. This would be fixed in subsequent
commits.
Add the behave tests, that cover the POST /restart (but not DELETE).
Originally Exhibitor was supported in the ZooKeeper class and
configuration for Exhibitor was taken also from `zookeeper` section in
the yaml config file. In fact, Exhibitor just extends ZooKeeper and now
it is reflected in the code and also Exhibitor got it's own section in
the config.yaml file. It will make it easier to configure Exhibitor
hosts and port via environment variables when PR#211 will be merged.
It could take up to 10 seconds to create replication slot.
In addition to that when replica fails to connect to the master via
streaming replication it doesn't retry immediately, but with some
timeout (5 seconds). 10 + 5 == 15 what causes replication check
scenarios fail.
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.
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.
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.
