Release for PostgreSQL 10

5

It would be great to get a release containing the PostgreSQL 10 support that landed in https://github.com/wal-e/wal-e/pull/339

How to ensure charm apt dependencies

10

Before a charm does 'import yaml' or 'import psycopg2', we need to ensure that these non-core dependencies are installed on the host system. Currently, it looks like we need a...

juju-info not supported

5

The implicit `juju-info` peer relation is not supported by the operator framework. The framework assumes all relations are defined in `metadata.yaml`, which is otherwise true.

is_doomed()

2

It is useful in a number of situations to know that the current unit is being torn down. This is exposed by charmhelpers as `charmhelpers.core.hookenv.is_doomed()`. Current implementation uses `goal-state`, but...

Test harness relations missing Juju managed data

4

The `ingress-address` and `egress-subnets` relation data is maintained by Juju, and often required. The Operator Framework test harness does not initialize this information when doing harness.add_relation_unit(), so relation-joined handlers can...

Test harness relations cannot be initialized with data

2

A test relation is initialized using `harness.add_relation_unit` and `harness.update_relation_data`. A side effect of this needing two calls is the relation-joined handlers get called between the two calls, and will always...

Helper library of common operations

3

There are many common operations that charms need to perform on the deployed machine to setup and maintain the deployed software. Many of these have accumulated in the charm-helpers library....

Are application relation settings inherantly racy?

3

I've been pondering code like this: ```python class MyCharm(CharmBase): def __init__(self, *args, **kw): super().__init__(*args, **kw) self.framework.observe(self.on.my_relation_joined, self) def on_my_relation_joined(self, event): if self.model.unit.is_leader(): event.relation[event.unit.app]['secret'] = mkpasswd(128) ``` I very much like...

Expose open-port and close-port hook tools

10

The `open-port` and `close-port` Juju hook environment tools are not exposed by the operator framework. It would be good if the framework handled closing the old port when a new...

Defer important status messages until commit?

2

A common problem with charms has been ensuring workload_status contains the most important information, and not overwritten. For example, ensuring that if charm code puts a unit into a 'blocked'...
