since there'll be a bunch of threads running functional test tasks at
the same time, there's no point always trying to start from the same
second and then stepping back to the same one-second-back file each
time. Also, this leads us to an increased risk of race conditions.
This change takes the same thirty second range, but shuffles it. The
tests, since they're no longer deterministic, now use a new Matcher
object (w/ credit to alexey) to match any filename from within that
thirty second range
when a test letter is created on dev or preview, we upload a file to
the dvla ftp response bucket, to test that our integration with s3
works. s3 triggers an sns notification, which we pick up, and then we
download the file and mark the letters it mentions as delivered.
However, if two tests run at the same time, they'll create the same
file on s3. One will just overwrite the next, and the first letter will
never move into delivered - this was causing functional tests to
intermittently fail.
This commit makes the test letter task check if the file exists - if it
does, it moves back one second and tries again. It tries this thirty
times before giving up.
This was because the rate_multiplier was being added as 1 and 1.0 which was not resolving to the same.
This updates the table to use Integrer.
Also changed the logging for the task.
If Monday or Tuesday check for letters still sending after 4 days.
If Saturday or Sunday do nothing
If Wed, Thurs, Fri check for letters still sending after 2 days
Added test for Tuesday, corrected tests after the correction to query.
be known. Added the notification id to the logging message so that
the notification can be traced through the logging system by knowing
the notification id, making it easier to debug. Also changed to raise an
exception so that alerts are generated. This way we should get an email
to say that there has been an error.
application. If the Anti-virus app fails due to s3 errors or ClamAV
so does not scan (even after retries) the file at all an error needs
to be raised and the notification set to technical-failure.
Files should be moved to a 'folder' a separate one for ERROR and FAILURE.
* Added new letter task to process the error
* Added a new method to letter utils.py to move a file into an error or
failure folder based on the input
* Added tests to test the task and the utils.py method
- precompiled PDFs sent by test key uploaded to scan bucket
- set status to VIRUS-SCAN-FAILED for pdfs failing virus scan rather than PERMANENT-FAILURE
- Make call to AV app for precompiled letters sent via a test key, and set notification status to PENDING-VIRUS-SCAN
