We don't seem to use recorded queries or modification tracking anywhere
in the app, and both features potentially increase memory usage.
This removes deprecated SQLALCHEMY_COMMIT_ON_TEARDOWN options. It's
been removed from the docs and the default matches the value we set
anyway.
Added cancelled letters to the number of failed letters in the statistics
that get used for the dashboard. At some point, we want to stop
including cancelled letters in the stats, but for now this keeps things
consistent with our current letter failure state, permanent-failure.
It can be useful to get a notification by id while checking that the
notification belongs to a given service. This changes the
get_notification_by_id DAO function to optionally also filter by
service_id so that we can check this.
Letters should always have a reference, because that’s what DVLA use to
tell us when they’ve sent a letter.
If a letter has a reference of `None` then DVLA say they’ve sent a
letter with a reference of `'None'`. This means we can never reconcile
the letter, which means it stays in `created`, which means it never
gets billed.
We don’t think this has affected any real letters yet, just ones that
we’ve sent as tests.
By default, SQLAlchemy will start a transaction with an
existing connection without checking that the connection
is still valid.
Enabling "pre-ping" makes the ORM send a `SELECT 1` when
acquiring a connection, which should help avoid some errors
caused by connections breaking during a DB failover.
The added statement has a constant overhead for all transactions,
so we should only keep it enabled when we're planning to switch
or upgrade the database server.

Running an update before setting the column default value reduces
the time the table is locked (since most rows don't have a NULL
value anymore), but the migration takes slightly longer to run
overall.
Also test deleting jobs with flexible data retention
Also update tests for default data retention following logic
change: dao_get_jobs_older_than_data_retention now counts
today at the start of the day, not at a time when function runs
and updated tests reflect that
Services reaching rate limits are triggering our alerts and make it
hard to find actual exceptions in the logs.
As far as the API is concerned this is not an exceptional state,
so we shouldn't log it as such.
Bumped notifications-utils to 3.7.0. Version 3.7.0 includes the
`convert_utc_to_bst` and `convert_bst_to_utc` functions and the
`LETTER_PROCESSING_DEADLINE` constant, so these have been removed from
this repo and anywhere using these has now been updated to get these
from `notifications-utils`.
Also bumped pytest by a patch version to bring in a bug fix.
When we first built letters you could only send them via a CSV upload, initially we needed a way to send those files to dvla per job.
We since stopped using this page. So let's delete it!
It was initialy called "rename" which does not comply with
RESTful CRUD (create, update, read, delete) naming practice.
We remove the 'rename' operation in favour of template folder
resource update endpoint as it allows us to extend it with other
attributes.
