This deletes a big ol' chunk of code related to letters. It's not everything—there are still a few things that might be tied to sms/email—but it's the the heart of letters function. SMS and email function should be untouched by this.
Areas affected:
- Things obviously about letters
- PDF tasks, used for precompiling letters
- Virus scanning, used for those PDFs
- FTP, used to send letters to the printer
- Postage stuff
* notify_db fixture creates the database connection and ensures the test
db exists and has migrations applied etc. It will run once per session
(test run).
* notify_db_session fixture runs after your test finishes and deletes
all non static (eg type table) data.
In unit tests that hit the database (ie: most of them), 99% of the time
we will need to use notify_db_session to ensure everything is reset. The
only time we don't need to use it is when we're querying things such as
"ensure get X works when database is empty". This is such a low
percentage of tests that it's easier for us to just use
notify_db_session every time, and ensure that all our tests run much
more consistently, at the cost of a small bit of performance when
running tests.
We used to use notify_db to access the session object for manually
adding, committing, etc. To dissuade usage of that fixture I've moved
that to the `notify_db_session`. I've then removed all uses of notify_db
that I could find in the codebase.
As a note, if you're writing a test that uses a `sample_x` fixture, all
of those fixtures rely on notify_db_session so you'll get the teardown
functionality for free. If you're just calling eg `create_x` db.py
functions, then you'll need to make you add notify_db_session fixture to
your test, even if you aren't manually accessing the session.
Since we’ve doubled the number of rows in a job, jobs can take twice as
long to insert all the notifications. We don’t check for missing rows
until we’re pretty confident that the original tasks have finished
processing. This means we need to double the time we wait to still be
as sure.
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.
Rather than showing all jobs that have been ‘copied’ from a contact list
I think it makes more sense to group them under the contact list. This
way it’s easier to see what messages have been sent to a given group of
contacts over time.
Part of this work means the API needs to return only jobs that have been
created from a given contact list, when asked.
This is only necessary because there is currently a job that is old, but had 1 row created a couple days later. So now there is 1 notifications for the job where the rest have been purged.
Sometimes a job finishes but has missed a row in the middle. It is a mystery why this is happening, it could be that the task to save the notifications has been dropped.
So until we solve the missing let's find missing rows and process them.
A new scheduled task has been added to find any "finished" jobs that do not have enough notifications created. If there are missing notifications the job processes those rows for the job.
Adding the new task to beat schedule will be done in the next commit.
A unique key constraint has been added to Notifications to ensure that the row is not added twice. Any index or constraint can affect performance, but this unique constraint should not affect it enough for us to notice.
For example if a file is uploaded on Aug 1, but scheduled for Aug 3, the csv file will be deleted 2 days before the notifications.
This will cause an error for on the jobs pages if the download report link is clicked.
This content was first done without help of content designer so
now it is improved with the help of one. New content is more
in line with the content in the admin app and more human-readable
and following GOV.UK standard.
test can_letter_job_be_cancelled closer to the code
test dao_cancel_letter_job closer to the code
Mock out calls in cancel_letter_job to test just that method
we previously always read from NotificationHistory to get the
notification status stats for a job. Now, if the job is more than three
days old read from ft_notification_status table, otherwise read from
the notifications table (to keep live updates).
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
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!
