To ensure consistent fieldpath matching for events, we generate the fieldpath matching using protobuf definitions. This is done through a plugin called "fieldpath" that defines a `Field` method for each type with the plugin enabled. Generated code handles top-level envelope fields, as well as deferred serialization for matching any types. In practice, this means that we can cheaply match events on `topic` and `namespace`. If we want to match on attributes within the event, we can use the `event` prefix to address these fields. For example, the following will match all envelopes that have a field named `container_id` that has the value `testing`: ``` ctr events "event.container_id==testing" ``` The above will decode the underlying event and check that particular field. Accordingly, if only `topic` or `namespace` is used, the event will not be decoded and only match on the envelope. Signed-off-by: Stephen J Day <stephen.day@docker.com>
