This was not picked up by tests because scheduled jobs are run immediately
and in the current thread (and therefore the current database transaction).
This particular case sometimes occurs inside multiple nested transactions,
so simply moving the offending line outside of the transaction is not enough.
Implemented TransactionHelper, which allows us to use `TransactionHelper.after_commit`
to define code to be run after the current transaction has been committed.
Use this event to filter the list of auto bumped topics.
EG:
on(:filter_auto_bump_topics) do |_category, filters|
filters.push(->(r) { r.where(<<~SQL)
NOT EXISTS(
SELECT 1 FROM topic_custom_fields
WHERE topic_id = topics.id
AND name = 'accepted_answer_post_id'
)
SQL
})
end
- We spread out bumping through the day, if you are bumping
4 topics then a topic will be bumped every 6 hours
- We add a small, bumping action at the bottom of the post to
denote a topic got bumped
```
change_column :topic_views, :ip_address, :inet, null: true
```
translates to
```
"ALTER TABLE \"topic_views\" ALTER COLUMN \"ip_address\" TYPE inet"
```
which locks the whole table while the migration is taking place.
### navigate_to_first_post_after_read setting for categories
When enabled on categories logged on users will return to OP after
reading the entire category. (useful for documentation categories)
### num_auto_bump_daily
Set a number of topics that will automatically bump daily on a category.
- Every 15 minutes we will check if any category has this setting
- Categories with the setting are shuffled
- We exclude pinned, closed, category description and archived topics
- Maximum of 1 topic for the list of categories is bumped till limit reached per category
- We always try to bump oldest first
- Limit is elastic using a RateLimiter that ensures that we only bump N per day
Also some minor organisation on category settings
Froze strings on category.rb
