When posts or topics are deleted we don't want to immediately delete associated bookmarks, so we have a grace period to recover them and their reminders if the post or topic is un-deleted. This PR adds a task to the Weekly scheduled job to go and delete bookmarks attached to posts or topics deleted > 3 days ago.
Introduces a new site setting `max_notifications_per_user`.
Out-of-the-box this is set to 10,000. If a user exceeds this number of
notifications, we will delete the oldest notifications keeping only 10,000.
To disable this safeguard set the setting to 0.
Enforcement happens weekly.
This is in place to protect the system from pathological states where a
single user has enormous amounts of notifications causing various queries
to time out. In practice nobody looks back more than a few hundred notifications.
Adds the settings:
raw_email_max_length, raw_rejected_email_max_length, delete_rejected_email_after_days.
These settings control retention of the "raw" emails logs.
raw_email_max_length ensures that if we get incoming email that is huge we will truncate it removing uploads from the raw log.
raw_rejected_email_max_length introduces an even more aggressive truncation for rejected incoming mail.
delete_rejected_email_after_days controls how many days we will keep rejected emails for (default 90)
Zeitwerk simplifies working with dependencies in dev and makes it easier reloading class chains.
We no longer need to use Rails "require_dependency" anywhere and instead can just use standard
Ruby patterns to require files.
This is a far reaching change and we expect some followups here.
This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.
Test suite passes now, but there may be some stuff left, so we will run
a few sites on a branch prior to merging
After careful analysis of large data-sets it became apparent that avg_time
had no impact whatsoever on "best of" topic scoring. Calculating avg_time
was a very costly operation especially on large databases.
We have some longer term plans of introducing other weighting that is read
time based into our scoring for "best of" and "top" topics, but in the
interim to stop a large amount of work that is not achieving any value we
are removing the jobs.
Column removal will follow once we decide on a new replacement metric.
Revamped system for managing authentication tokens.
- Every user has 1 token per client (web browser)
- Tokens are rotated every 10 minutes
New system migrates the old tokens to "legacy" tokens,
so users still remain logged on.
Also introduces weekly job to expire old auth tokens.
