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
At the moment we display the count of scheduled jobs on the dashboard
by sending all the scheduled jobs to the admin app and letting it work
out the stats.
This is inefficient and, because the get jobs response has a page size
of 50, becomes incorrect if a service schedules more than 50 jobs.
This commit adds a separate endpoint which gives the admin app the stats
it needs directly and correctly.
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.
We want to add another argument here, and doing so would make the line
length too long with all the arguments on one line.
Also uses the * operator to enforce keyword-only arguments.
Currently if you visit the job page and the job is older than the data retention the totals on the page are all wrong because this query gets the counts from the notification table. With this change the data should always be correct. It also eliminates the need for looking at data retention. If the job is new and nothing has been created yet (i.e. the job hasn't started yet) then the page should show the correctly because the outcomes are empty (as expected), once the notifications for the jobs are created the numbers will start going up.
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.
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!
it's used in a few places - it should definitely know what timezones
are and return datetimes rather than dates, which are hard to work with
in terms of figuring out how tz aware they are.
* Deleted the statistics DAO
(this was used for the job statistics tasks)
* Deleted the functions in the jobs DAO which are no longer used
(the functions that were used for the job-stats endpoints)
so they can be distinguished on the frontend.
Also, some related cleanup:
* don't show test api letters on the frontpage
* make sure the subject is returned from the API for letters
* make sure the letter's address is returned for letters
Replace labels by adding a key kwarg in the model for status.
We still need this as sqlalchemy attmempts to look for `notification_status`
on the model (Notification/NotificationHistory). To achieve true ORM mapping
(map status -> notification_status) we need the key kwarg.
