This commit introduces 2 features:
1. DISCOURSE_COMPRESS_ANON_CACHE (true|false, default false): this allows
you to optionally compress the anon cache body entries in Redis, can be
useful for high load sites with Redis that lives on a separate server to
to webs
2. DISCOURSE_ANON_CACHE_STORE_THRESHOLD (default 2), only pop entries into
redis if we observe them more than N times. This avoids situations where
a crawler can walk a big pile of topics and store them all in Redis never
to be used. Our default anon cache time for topics is only 60 seconds. Anon
cache is in place to avoid the "slashdot" effect where a single topic is
hit by 100s of people in one minute.
- prevents keyboard from being invoked when textarea is disabled
- avoids scrolling up when switching focus from title to textarea on new topic creation
Start tracking the date an api key was last used. This has already been
the case for user_api_keys.
This information can provide us with the ability to automatically expire
unused api keys after N days.
The URL '/images/transparent.png' will be used in the cooked content if upload record not found. In that case we have to use 'short_url' as image src in 'post.each_upload_url' method.
This allows custom plugins such as prometheus exporter to log how many
requests are stored in the anon cache vs used by the anon cache.
This metric allows us to fine tune cache behaviors
This was primarily an issue on mobile, where after clicking the "Messsage" button in the user card, the composer would load behind the user card overlay.
When opening authentication popup, start with an on-site URL. Opening "about:blank", and then POSTing the form does not send same-site=Lax cookies. Opening the popup to a page on the site domain, and then POSTing the form, works successfully.
* FIX: User should get notified when a post is deleted
* FEATURE: Notify posters when restoring flagged posts
* Fix typo

Prior to this commit if we ever checked in a per_host directive and scheduled
job was previously global, total chaos could ensue as a feedback loop would
start
We very rarely used per_host to date, but just started making use of it
for heartbeats
We refactored some code to avoid app event leak in tests at c462c2f2
Unfortunately this broke all background notifications in title and they
were broken for the past multiple months.
This reverts commit e805d44965.
We now have mechanisms in place to ensure heartbeat will always
be scheduled even if the scheduler is overloaded per: 098f938b
When there is an overridden text in the database that belongs to
a pluralized key which doesn't exist in English anymore, the
Customize Texts admin page was unusable. This stops those keys from
ever being returned by a search.
* The read indicator now shows up when no member has read the last post of the topic (written by a non-member)
* The read indicator works on mobile and receives live updates from message bus
* The icon we display in the topic list was changed
* Added a title to the indicator to indicate its purpose when hovering over it
The client-side theme-selector would always apply the first in a series of file change notifications. This has been fixed, so it now applies the most recent notification.
Duplicate notifications were being sent because
- The remote_theme autosave was causing every change notification to be doubled
- Color scheme change notifications were being sent every time a theme was uploaded, even if the colors were unchanged
These duplicate notifications have been fixed, and a spec added to ensure it does not regress in future
Under extreme load on large databases certain regular jobs can take quite
a while to run. We need to ensure we never starve a sidekiq from running
mini scheduler, cause without it we are unable to queue stuff such as
heartbeat jobs.
Databases can have a lot of user actions, self joining and running an
aggregate on millions of rows can be very costly
This optimisation will reduce the regular window of consistency down to 13
hours, this ensures the job runs much faster
In some very specific cases (large sites) shared drafts can introduce a
performance hit due to the mechanism used to filter out topics
This avoids the entire process when shared drafts are not enabled
