When we get a callback from SES, we identify the notification by the
SES reference that we set on the notification after sending. When we
wrote the log message, we assumed that we'd always have a notification
for every callback, so if one couldn't be found we would raise an error
log. This isn't the case for a few reasons:
* We might receive a callback before the sender worker has persisted
the reference to the database.
* We might have deleted the notification, especially if the service has
a short data retention period
* We sometimes receive callbacks for references that we have no record
of whatsoever (this is quite alarming but we have no way of knowing
why this happens)
The error logs were happening pretty frequently, and we don't have a
real way to solve them at the moment, so lets cut down on noise and
downgrade them to info level for now.
Step 1 of 2 of turning on folders for all services.
We think it’s a feature which will be useful for the majority of
services, and we think we’ve done enough research to know that it’s
mature enough to release to all services.
previously, it was too loose - checking `"name" in str(exc)` returns
false positives.
By changing from three if statements to a loop we can cut down on
unnecessary code (and ensure that the returned objects are consistent),
and by using the full check constraint name we can be sure that we're
only capturing exactly the right errors. Additionally, don't return
the original data in the error message - it's obvious what the name is
because it'll be populated in the form you just filled in.
However, until we can create a letter without a logo, we will still default to hm-government, because the dvla_organisation is set on the service.
This does simplify the code.
Also removed the inserts to letter_branding in the data migration file, because we can deploy this before the rest of the work is finished. But we will need to do it later.
make a decorator that pings cronitor before and after each task run.
Designed for use with nightly tasks, so we have visibility if they
fail. We have a bunch of cronitor monitors set up - 5 character keys
that go into a URL that we then make a GET to with a self-explanatory
url path (run/fail/complete).
the cronitor URLs are defined in the credentials repo as a dictionary
of celery task names to URL slugs. If the name passed in to the
decorator isn't in that dict, it won't run.
to use it, all you need to do is call `@cronitor(my_task_name)`
instead of `@notify_celery.task`, and make sure that the task name and
the matching slug are included in the credentials repo (or locally,
json dumped and stored in the CRONITOR_KEYS environment variable)
Currently, admin app requests service statistics (with notification
counts grouped by status) and template statistics (with counts by
template) in order to display the service dashboard.
Service statistics are gathered from FactNotificationStatus table
(counts for the last 7 days) combined with Notification (counts for
today).
Template statistics are currently gathered from redis cache, which
contains a separate counter per template per day. It's hard for us
to maintain consistency between redis and DB counts. Currently it
doesn't update the count for cancelled letters, counter resets in
the middle of the day might produce a wrong result for the rest of
the week and cleared redis cache can't be repopulated for services
with low data retention periods).
Since FactNotificationStatus already contains separate counts for
each template_id we can use the existing logic with some additional
filters to get separate counts for each template and status combination,
which would allow us to populate the service dashboard page from one
query response.
If a precompiled letter can't be opened (e.g. because it isn't a valid
PDF) we were setting its billable units to 0, but not moving it to the
invalid PDF bucket. If a precompiled letter failed sanitisation, we were
moving it to the invalid PDF bucket but not setting its billable units
to 0.
This commit makes sure that we always set the billable units to 0
and move the PDF to the right bucket if it fails sanitisation or can't be
opened.
