This commit introduces an ultra low priority queue for post rebakes. This
way rebakes can never interfere with regular sidekiq processing for cases
where we perform a large scale rebake.
Additionally it allows Post.rebake_old to be run with rate_limiter: false
to avoid triggering the limiter when rebaking. This is handy for cases
where you want to just force the full rebake and not wait for it to trickle
This corrects 2 issues:
First is a regression with d7c08e21 for some reason dependent :delete_all
respects default scopes where-as dependent :destroy bypasses it.
Secondly, we were keeping orphan user actions around on user destroy, this
ensures we remove all the user actions not only ones that originated by
the user.
So for example: if I like a post of user A we create a user action saying I
did that, but once user A is deleted we were not removing the action leading
to an orphan action in the database.
Users can have 100s of thousands of post and user actions, we do not want
to destroy each individually cause the tracking is enormous and the amount
of queries we would need is enormous.
This gives up on the `after_commit` hook on `post_actions` which ships a message
to clients to synchronize a post, so some phantom post_actions may remain
in the UX in the rare occasion we delete a user. The phantoms will be gone
on reload.
This should only change the order on freshly imported instances with no likes.
This makes the user summary show the latest topics/posts/links instead of the firsts until the users get some likes.
This allows us to run regular rebakes without starving the normal queue.
It additionally adds the ability to specify queue with `Jobs.enqueue` so
we can specifically queue a job with lower priority using the `queue` arg.
Before this patch, a high trust level user could flag something
and have an action be taken, as well as skipping the flag queue.
Now, if a TL3/TL4 cause an action, the flag will skip the minimum
visibility check and allow staff to review it.
FIX: buildTranslationTree was erroring when translations overlapped (ie. ":-)" and ":-))")
FIX: emoji translations wasn't working properly when translations overlapped
Previously we only allowed one image optimization per machine, this meant there
was cross talk between avatar resizing and Sidekiq. This could lead to large
amounts of starvation when optimized image version changed which in turn could
block the Sidekiq queue.
This increases amount of allowed load on machines but this is preferable to
having crosstalk between avatar resizing and Sidekiq.
Some cloud providers (Google Memorystore) do not support any CLIENT commands
By setting :id to nil in the redis config hash we can avoid these commands.
This adds a special global setting GCE users can enable:
`DISCOURSE_REDIS_SKIP_CLIENT_COMMANDS = true`
We have the periodical job that regularly will rebake old posts. This is
used to trickle in update to cooked markdown. The problem is that each rebake
can issue multiple background jobs (post process and pull hotlinked images)
Previously we had no per-cluster limit so cluster running 100s of sites could
flood the sidekiq queue with rebake related jobs.
New system introduces a hard limit of 300 rebakes per 15 minutes across a
cluster to ensure the sidekiq job is not dominated by this.
We also reduced `rebake_old_posts_count` to 80, which is a safer default.
This reverts commit 993f847a2c.
There is an edge case where the link click redirect fails when the URL has trailing slash. Need to figure out a better fix for this.
Previously we had no idea what algorithm generated thumbnails, this starts tracking the version.
We also bumped up the version to force all optimized images to be generated. This is important cause we recently introduced pngquant which results in much smaller images.
This feature ensures optimized images run via pngquant, this results extreme amounts of savings for resized images. Effectively the only impact is that the color palette on small resized images is reduced to 256.
To ensure safety we only apply this optimisation to images smaller than 500k.
This commit also makes a bunch of image specs less fragile.
Previously if upload had missing width and height we would calculate
on first use BUT we (me) forgot to save this to the database
This was particularly bad on home page cause category images (when old)
miss dimensions.
