In order to set a message as temporary-failure, we check if it is in pending status first.
Otherwise a delivery receipt for failure is set to permanent failure.
If the notification has a status == sending then update the status otherwise do not update the status.
In other words do not change the status more than once.
Status codes from mmg are:
2: UNDELIVERABLE Message is undeliverable.
3: DELIVERED Message is delivered.
4: EXPIRED Message is expired.
5: REJECTED Message is rejected.
Refactor process_firetext_responses
Removed the abstract ClientResponses for firetext and mmg. There is a map for each response to handle the status codes sent by each client.
Since MMG has about 20 different status code, none of which seem to be a pending state (unlike firetext that has 3 status one for pending - network delay).
For MMG status codes, look for 00 as successful, everything else is assumed to be a failure.
- when a provider callback occurs and we update the status of the notification, also update the statistics table
Adds:
- Mapping object to the clients to handle mapping to various states from the response codes, this replaces the map.
- query lookup in the DAO to get the query based on response type / template type
Tests around rest class and dao to check correct updating of stats
Missing:
- multiple client callbacks will keep incrementing the counts of success/failure. This edge case needs to be handle in a future story.
