This changes the scheduled task to raise an alert if letters are still
sending from 1530 to 1700. DVLA have reported that our "monitoring is
executing just before we actually mark them as ‘despatched’ and send
you the feedback files." and asked us to make the check a little later.
We don't actually contact DVLA until the morning after the alert anyway,
so this won't affect the process of getting in touch with them.
This change will require Cronitor to be updated for the new time.
This makes a few changes to:
- Make local development consistent with our other apps. It's now
faster to start Celery locally since we don't try to build the
image each time - this is usually quick, but unnecessary.
- Add support for connecting to a local Redis instance. Note that
the previous suggestion of "REDIS = True" was incorrect as this
would be turned into the literal string "True".
I've also co-located and extended the recipes in the Makefile to
make them a bit more visible.
Before we implemented ‘cancel’ any updates to a broadcast went through
the admin app. This meant the admin app could deal with clearing the
cache any time a broadcast was updated by a user performing an action.
Now that a broadcast can be updated without the admin app being involved
we have another place we need to clear the cache from.
If we don’t do this then the broadcast can look like it’s still going
even though it’s successfully been cancelled.
With the changes we will be making to email branding in admin it's
useful to know the ID of the NHS email brand. This makes it easier to
show a preview of the branding.
This means that the ID will need to be consistent across environments,
so this changes the details of the NHS brand in the dev, preview and
staging environments to match the production data.
The migration
- Removes NHS branding from existing services
- Removes NHS branding from any orgs which had it as their default
- Deletes the NHS branding row if it exists
- Inserts a new NHS branding row with details which match those in
production
This does have the effect of removing NHS branding from people's local
and preview services and orgs (NHS branding doesn't exist on staging),
but this does not affect real teams. The NHS logo with a filename of
'1ac6f483-3105-4c9e-9017-dd7fb2752c44-nhs-blue_x2.png' exists in the
logo S3 bucket for all environments.
Because the `<reference>` field of a `cancel` message can contain an
arbitrary number of items it’s possible for it to reference more than
one current alert.
In this case it is ambiguous which alert should be cancelled, so we
should raise a custom error.
This will help people know that they have to manually go into Notify and
figure out which alert(s) to cancel there.
It is possible that, among the references Environment Agency give us for
which broadcast to cancel, there could be references for older, already
expired broadcasts.
This would be the case if someone cancelled a broadcast in Notify, then
issued and try to re-cancel another broadcast to the same area. The
Flood Warning Service has no way of knowing that the first broadcast has
been cancelled in Notify already, so it would add the reference to the
list of things to be cancelled.
We can avoid this from happening by filtering-out already-cancelled and
expired broadcasts before looking up which one should be cancelled.
The XML for an alerts requires a `<description>` field. The XML for
a `<cancel>` may have a `<description>` field populated (although we
ignore the contents) but it may also be empty.
This commit updates the schema to leave the all the validation to the
view layer, which can decide when or when not to validate the content of
the `<description>` field.
References are optional, and we fixed errors when they are not provided

This commit amends the tests so that they cover the `Alert` message type
as well as the `Cancel` (which is already covered).
Previously we were looping over data from the Notifications/History
table and then shovelling it into the status table, one row at a time
- plus an extra delete to clean up any existing data.
This replaces that with a batch insertion, similar to how we archive
notifications [1], but using a simple subquery (via "from_select" [2])
instead of a temporary table.
To make the select compatible with the insert, I've used "literal"
to inject the constant pieces of data, so each row has everything it
needs to go into the status table.

This is consistent with the way we do billing updates [1] and is a
bit less clunky. Functionally it should be the same - note that the
tests already cover the "overwriting" behaviour if a row exists.

This fixes the app crashing - apparently due to a lack of free
memory. Looking over the last month, we can see it's been hovering
at ~90% utilisation. 512M seems like a good compromise to avoid
this happening again vs paying for what we use.
The limit was last changed 5 years ago:

If someone tries to cancel a broadcast but the references don’t match
and existing broadcast we correctly return a 404.
If they don’t provide any references then we get an exception. This
commit catches the missing references and returns a 400. I think this
is more appropriate because it’s malformed request, rather than a
well-formed request that doesn’t match our data. It also lets us write a
more specific and helpful error message.
This column has been superseded by a new column named
created_by_api_key_id.
Also create constraint checking that we know who created broadcast
Also move data so that constraint is met before instatiating it.
Addresses [1].
Previously the query would always use UTC midnight, even after we
had switched to BST (+1h). We store timestamps as naive UTC in our
DB - without a timezone - but we want the query to work in terms
of GMT / BST so we adjust for that - BST midnight is 11PM in UTC.

This takes a similar approach to the nightly deletion task so that
we only create sub-tasks when there are actually notifications to
aggregate for a given type and day [1].
We're making this change to stop the duplication errors we're getting
at the moment and ensure the task can scale to more messages and more
services. There are two parts to this:
- Each subtask should now run within the 5 minute visibility timeout.
However, they may still be duplicated if the parent task overruns [2].
- The parent task creates a mininal number of subtasks, and the query
to determine this is very fast for a normal process day (milliseconds).
Since all tasks will run quickly, there should be no more duplication.
In order to test this more nuanced task, I rewrote the tests:
- One test checks the subtask is called correctly.
- One test checks we create all the right subtasks.

These can be inferred elsewhere:
- Task creation is obvious from task execution. If we're concerned
about a specific service, we can check the updated times on the DB
records, since all records are recreated each time this runs.
- Task starting is already logged.
- Task completion is already logged. The number of rows updated can
also be inferred from the DB.
The log I've found useful is the one about fetching the data, and
I've also added another to time how long it takes to insert the data,
as both could be sources of poor performance.
Arguably we should use metrics for this sort of thing, but logs are
easier in practice for the metric systems we have.
table. Also add created_by_api_key_id column that will supersede
api_key_id_column.
We do migration and code in separate PRs to make it easier to
downgrade if anything goes wrong.
