There are two fun quirks of postgres/sql that we need to work around:
* any `x = y` where x or y is NULL returns NULL, rather than false.
* check constraints accept NULL or true values as good.
so, the check `postage in ('first', 'second')` returns `null` rather
than `false` when postage is null itself. This surprisingly passes the
check constraint. To get around this, we have to add an explicit not
null check as well.
A not valid constraint only checks against new rows, not existing rows.
We can call VALIDATE CONSTRAINT against this new constraint to check
the old rows (which we know are good, having run the command from
74961781). Adding a normal constraint acquires an ACCESS EXCLUSIVE
lock, but validate constraint only needs a SHARE UPDATE EXCLUSIVE lock.
see 9d4b8961 and 0a50993f for more information on marking constraints
as not valid.
sets all letters in notification history (and notifications) to
"second", so that there's no null letters for billing etc. Commits in
ten day chunks (up to ~30k letters)
To start with this will be an attribute on the service, at the time the notification is created it will look at Service.letter_class to decide what class to use for the letter.
This PR adds Service.letter class as a nullable column.
Updated the create_service and update_service method to default the value to second.
Subsequent PRs will add the check constraint to ensure we only get first or second in the letter_class column and make that column nullable.
This can't be done all at once because it will cause an error if someone inserts or updates a service during the deploy.
Sets the updated_at to current time when the NotificationHistory
is modified (which happens occasionally for example to set status
to returned letter).
There was a datetime bug in the query which resulted in files not being sent to the postal provider.
The trigger-letter-pdfs-for-day task is no longer needed, so rather than fix the query just call collate_letter_pdfs_for_day directly.
Less code is always better.
Deployment considerations: I realized this is strictly not backwards compatible if the scheduled job is in progress and a task is on the queue that no longer exists. This is ok since we will deploy this well before 17:50.
The concern about performnace degrading has been thought through. We do not believe there will be an adverse effect since the high volume users do not send off messages.
Adds an API endpoint `/letters/returned` that accepts a list of
notification references and creates a task to update their status.
Adds a new task that uses the list of references to update the status
of notifications to 'returned-letter'.
The update is currently done using a single query and logs the
number of changed records (including notification history records).
This could potentially be done within the `/letters/returned` endpoint,
but creating a job right away allows us to extend this more easily
in the future (e.g. logging missing notifications or adding callbacks).
The job is using the database tasks queue.
For returned letter updates most notifications won't exist in the
notifications table, so in order to find out whether the reference
matches any known letters we need to check the count of updated
history records.
We need to update letter notifications with a new status when DVLA
gives us a list of references for returned letters.
This adds the new status to the models and the DB.
DVLA call this 'returned mail', so I'm using it as the status name
since it seems less ambiguous than 'returned'.
Does two things:
1. Revert "Revert "Add unique constraint to email branding domain""
This reverts commit af9cb30ef3.
2. Don’t allow empty string in email branding domain
Columns with multiple `null`s can have a uniqueness constraint. Columns
with multiple empty string values are not considered unique.
This commit:
- removes any duplicate empty string values
- casts empty strings to null string any time these columns are updated
---
Squashed into this single commits because these two things are not
atomic as individual commits.
Brandings with a domain set should be considered canonical. It doesn’t
make sense to have the same domain set on multiple different email
brands – you can’t tell which one to use.
‘GOV.UK’ doesn’t make sense as a type of brand. It only made sense as
a type of branding that a service had.
Since we’ve:
- deprecated the service branding column
- made sure it’s not used as a value in the email branding table
we can remove this value from the table of possible brand types.
https://www.pivotaltracker.com/story/show/159986276
We are now setting the type of branding on the branding itself, not on
the service.
This commit switches over from looking in the old place (on the service)
to looking in the new place (on the branding).
Notify antivirus, on success, calls the process_virus_scan_passed taks.
Previously, this task would:
* update status to created (or delivered for test keys)
* copy the file from the scan bucket to either the live or test bucket
based on the results
* delete the old file in the scan bucket
We want it to:
* download file from scan bucket
* sanitise PDF using new template-preview functionality
* if sanitise failed, set to new status "validation-failed" and save
the pdf somewhere.
* send new pdf to live/test bucket
* update status to created (or delivered for test keys)
* delete the original file in the scan bucket
This PR does some of that:
* download file from scan bucket
* sanitise PDF using new template-preview functionality
* if sanitise failed, just log.
* send OLD pdf to live/test bucket
* update status to created (or delivered for test keys)
* delete the original file in the scan bucket
So if sanitising fails, we won't fall over and not deliver the letter,
we'll just log a message for now. If sanitise throws an unexpected
error (as opposed to a 400), we'll retry up to fifteen times (the same
as when creating a new letter). I've added the code for using the
sanitised pdf, but it's commented out for now
This header was introduced to ensure that no traffic was being
directed straight to the .cloudapps.digital domain. This was especially
useful for the non-production environments where access to the proper
domains is allowed for specific IP addresses while the cloudapps.digital
ones are open.
Moving to paas custom domains [1] will allow us to stop using the paas
proxies and, as a result, unbind the cloudapps.digital domain from our
apps.
This means that the X-Custom-Forwarder will become obsolete since all
our requests will be coming directly to our domain (albeit through
cloudfront) so any IP restriction can be implemented with a route
service [2].

There is a requirement for the colour of the banner to be different to the single id colour. In order to accomodate that we are adding two new columns for that data.
These columns will be updated manually and not done with a data migration.
A new column called domain has been added. This will be used as a default domain, if the user that creates the service has a matching domain this email brand will be set for the service.
This PR only adds the new columns to the model and db.

Admin, API and utils were all defining a value for SMS_CHAR_COUNT_LIMIT.
This value has been updated in notifications-utils to allow text
messages to be 4 fragments long and notifications-api now gets the value of
SMS_CHAR_COUNT_LIMIT from notifications-utils instead of defining it in
config.
Also updated some tests to check for the higher limit.
Admin app needs to get the service data retention for the specified
notification type, so to avoid iterating through the list of all
existing service data retention settings we restore the endpoint
to get the individual data retention period.
Allows getting notification counts for a given number of days to
support services with custom data retention periods (admin dashboard
page should still display counts for the last 7 days, while the
notifications page displays all stored notifications).
