history-meta's dynamic magic is insufficient for templates, where we
need to be able to refer to the specific history table to take
advantage of sqlalchemy's relationship management (2/3rds of an ORM).
So replace it with a custom made version table.
Had to change the version decorator slightly for this
Removed all existing statsd logging and replaced with:
- statsd decorator. Infers the stat name from the decorated function call. Delegates statsd call to statsd client. Calls incr and timing for each decorated method. This is applied to all tasks and all dao methods that touch the notifications/notification_history tables
- statsd client changed to prefix all stats with "notification.api."
- Relies on https://github.com/alphagov/notifications-utils/pull/61 for request logging. Once integrated we pass the statsd client to the logger, allowing us to statsd all API calls. This passes in the start time and the method to be called (NOT the url) onto the global flask object. We then construct statsd counters and timers in the following way
notifications.api.POST.notifications.send_notification.200
This should allow us to aggregate to the level of
- API or ADMIN
- POST or GET etc
- modules
- methods
- status codes
Finally we count the callbacks received from 3rd parties to mapped status.
if passed in, returns the service object with additional statistics
dictionary, which will be used in the admin app to populate dashboard
components. A new schema has been created for this to avoid clashing/
causing confusion with the existing schema, which is already used
for PUT/POST as well, and this schema can be easily tailored to
reduce ambiguity and lazy-loading
Add additional relationships to exclude in the ServiceSchema metaclass.
Marshmallow by default lazily loads relationships when dumping, so any
relationships we know we won't need, we can exclude and avoid a DB call.
Lots of tables are linked to services, so it loads a lot of tables.
So don't load statistics tables, since they're clearly not needed.
We *do* however want to return the users for the service - they're used
in a few places. If we're returning all services, then we don't want to
make separate queries for these users, so we modify the services_dao
queries to load users the first time round. This should speed up all
GET queries to the services endpoints, most notably pages that get many
services (platform_admin, choose service, login)
please ensure that any changes to notifications table happen through either dao_create_notification or dao_update_notification.
changed the notification status update triggered by the provider callbacks to ensure that sets updated_by and can update the history table.
also re-added the character_count so we can reconstruct billing data if needed.
revoking an api key the service it associated with was of course added
to db.session.dirty.
That resulted in an updated version of service being added to the
service history table that showed no visible difference from that
record immediately precending it as the change was to another table,
namely the api_key table. A new api key or revoked api key was correctly
added to api_key and api_key_history tables. However I think an
'unchanged' service history record may be a bit confusing as you'd need
to correlate with api_keys to work out what the change was.
I think it's best to just record the new/revoked api_key and not create
another version of the service.
This pr wraps the exisiting versioned decorator with one that take a
class which you are interested in versioning.
Using the new decorator you only get a new version and history record
for the class you pass to outer decorator.
If the exising behaviour is acceptable to the powers that be then by all
means ignore/close this pr.
adapted to recording inserts and updates.
This removes need to manually create history tables.
Our code still remains in control of when history records are
created.
