Refunds are now processed automatically. If the automated processing fails, the system falls back to the previous behavior of notifying the Support Team. Additionally, these calls are all made by the service user rather than the learner.

We should not be using custom signing keys for each service at this time. We may want to return to this strategy in the future; but, this is not the direction any of our other services are going in.

Some old mongo courses do not have this field, and the team has opted
to allow null values rather than inserting a default. This change
affects both course and subsection grades.

As discovered in load testing, if this task is run too quickly it
can ask for a newly-recorded score prior to the active transaction
finishing and writing to the database.

This functionality hasn't been used since it was introduced. It is superseded by the backpopulate_program_credentials management command. This is another commit in a series removing use of the old programs service from edx-platform.

When crawlers like edX-downloader make requests on courseware, they are
often concurrently loading many units in the same sequence. This causes
contention for the rows in courseware_studentmodule that store the
student's state for various XBlocks/XModules, most notably for the
sequence, chapter, and course -- all of which record and update user
position information when loaded.
It would be nice if we could actually remove these writes altogether
and come up with a cleaner way of keeping track of the user's position.
In general, GETs should be side-effect free. However, any such change
would break backwards compatibility, and would require close
coordination with research teams to make sure they weren't negatively
affected.
This commit identifies crawlers by user agent (CrawlersConfig model),
and blocks student state writes if a crawler is detected. FieldDataCache
writes simply become no-ops. It doesn't actually alter the rendering
of the courseware in any way -- the main impact is that the blocks
won't record your most recent position, which is meaningless for
crawlers anyway.
This can also be used as a building block for other policy we want to
define around crawlers. We just have to be mindful that this only works
with "nice" crawlers who are honest in their user agents, and that
significantly more sophisticated (and costly) measures would be
necessary to prevent crawlers that try to be even trivially sneaky.

Uses a Waffle Switch to route traffic between the programs and catalog services. A future commit will remove use of the switch and use the catalog exclusively.

Here are the 3 tasks over the last 30 days with average duration

All but ora2 seem fine to pass through the default queue, which has 3
