Reflects the new name of the feature.
Note that the name of the underlying table hasn’t changed because it’s
explicitly set to `service_whitelist`. Changing this will be a more
involved process.
It's clear that we need a way to track updates to a broadcast message.
It's also clear that we'll need some kind of audit log that captures
exactly what was sent out in a message.
This commit adds a new database table, `broadcast_event`, which maps 1:1
with CAP XML sent to the CBCs. We'll create one of these just before
sending out.
The main driver for this was that cancel and update messages need to
contain a list of references of all previous messages that they're
amending. This is of format `{sender},{identifier},{sent_timestamp}`,
and the identifier itself needs to be unique for each message.
spent WAY too long trying to figure out why my user wasn't being created
in tests. the user isn't created if their email already exists in the
system, but email isn't a required field when creating!
Note: I tried just removing the check to see if the user already exists,
but 16 tests try and create duplicate users. I'm of the belief we should
just fix all those tests but I didn't have the energy for it right now
The task was raising a JobIncompleteError, yet it's not an error the task is performing it's task correctly and calling the appropriate task to restart the job.
Also used apply_sync to create the task instead of send_task.
At the moment we return a count of recent jobs for contact lists, where
recent is defined as being within the service’s data retention period.
This lets us write nice bits of UI copy like ‘used 3 times in the last
7 days’. But it’s hard to write the copy for when the count is 0,
because this could be for one of two reasons:
- the contact list has never been used
- the contact list has been used, but not within the data retention
period for that channel
At the moment we can’t know which of those reasons is the case, so we
can’t write nice clear content like ‘never been used’.
This commit adds a property to contact lists which says whether they’ve
ever been used.
It also renames the existing, as-yet-unused property to make clear that
it’s only counting within the data retention (so can still be 0 even if
`has_jobs` is `True`).
Usage for all services is a platform admin report that groups letters by
postage. We want it to show `europe` and `rest-of-world` letters under a
single category of `international`, so this updates the query to do
that and to order appropriately.
New rows giving the prices of letters with a post_class of `europe` and
`rest-of-world` have been added to the `letter_rates` table. All rates
are currently the same for international letters.
task takes a brodcast_message_id, and makes a post to the cbc-proxy
for now, hardcode the url to the notify stub. the stub requires template
as the admin/api get it, so use the marshmallow schema to json dump it.
Note - this also required us to tweak the BroadcastMessage.serialize
function so that it converts uuids in to ids - flask's jsonify function
does that for free but requests.post doesn't sadly.
if the request fails (either 4xx or 5xx) just raise an exception and let
it bubble up for now - in the future we'll add retry logic
This done so that we do not use statsd on our http endpoint.
We decided we do not need metrics that this gave us. If we
change our minds, we will add Prometheus-friendly decorators
instead in the future.
make it clear that this is for the public api, and we shouldn't add
fields to it without considering impacts
also add the broadcast_messages relationship on service and template to
the exclude from the marshmallow schemas, so it's not included elsewhere
new broadcast_message table. contains a whole bunch of timestamps, a
couple of user ids for who created and who approved, some
personalisation and a template id/version. areas is a jsonb field - it
is expected that this will be an array, for example `["england",
"wales"]`
intended valid state transitions are as follows, from an initial status
of draft
* draft -> pending-approval, rejected
* pending-approval -> broadcasting, rejected, (draft maybe)
* broadcasting -> completed, cancelled
rejected, completed, cancelled and technical-failure are terminating
states.
also copy across the enum switching code from migration 0060 (adding
letter type).
had to go through the code and change a few places where we filter on
template types. i specifically didn't worry about jobs or notifications.
Also, add braodcast_data - a json column that might contain arbitrary
broadcast data that we'll figure out as we go. We don't know what it'll
look like, but it should be returned by the API
This prevents a race condition when we get delivery receipt before
updating notification to sending, and so the sending status would
supersede the delivered status, and the notification would time out
as temporary-failure after three days.
As we gradually move from statsd to prometheus, we change the metric to
be a prometheus metric rather than statsd.
The change worth pointing out is that we have dropped the 'successful'
and 'failed' statuses from the metrics. I don't think it's useful to
have these statuses. It's very rare for an inbound message to fail when
we receive it and when it does, we raise an error and see it in our
logs. We aren't going to be looking at a graph of it as it's a rare
event, not typical behaviour that we want to monitor with a graph.
This was broken because sometimes `service.permissions` is a list of
strings (for when we’re caching the service object) and sometimes it’s a
list of permission objects (when we’re dealing with ORM objects).
Because the validator code is shared, the least-messy way to fix it is
to make sure it can handle both types.
It can’t just take a list of permissions as argument, because it uses
other fields on the service.
It would be messy to rewrite the endpoint to use a serialised service
because the tests all expect to be dealing with database objects, so it
would be a faff to change what they’re mocking.
This commit turns off StatsD metrics for the following
- the `dao_create_notification` function
- the `user-agent` metric
- the response times and response codes per flask endpoint
This has been done with the purpose of not having the creation of text
messages or emails call out to StatsD during the request process. These
are the three current metrics that are currently called during the
processing of one of those requests and so have been removed from the
API.
The reason for removing the calls out to StatsD when processing a
request to send a notification is that we have seen two incidents
recently affected by DNS resolution for StatsD (either by a slow down in
resolution time or a failure to resolve). These POST requests are our
most critical code path and we don't want them to be affected by any
potential unforeseen trouble with StatsD DNS resolution.
We are not going to miss the removal of these metrics.
- the `dao_create_notification` metric is rarely/never looked at
- the `user-agent` metric is rarely/never looked at and can be got from
our logs if we want it
- the response times and response codes per flask endpoint are already
exposed using the gds metrics python library
I did not remove the statsd metrics from any other parts of the API
because
- As the POST notification endpoints are the main source of web traffic,
we should have already removed most calls to StatsD which should
greatly reduce the chance of their being any further issues with
DNS resolution
- Some of the other metrics still provide value so no point deleting
them if we don't need to
- The metrics on celery tasks will not affect any HTTP requests from
users as they are async and also we do not currently have the
infrastructure set up to replace them with a prometheus HTTP endpoint that
can be scraped so this would require more work
Because the IDs of our callback and inbound SMS APIs were stored in
lists instead of directly on the serialised model they weren’t getting
cast to a string before trying to JSONify them. And JSON doesn’t know
what to do with a UUID object.
For some reason this was only affecting the endpoint for fetching
inbound SMS.
The API needs these to check whether a service can send a notification.
This commit also updates all the tests in `test_validators.py` to take
a serialised service, not a database object.
