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
This change shows a notification number besides the flag icon in the
post menu if there is reviewable content associated with the post.
Additionally, if there is pending stuff to review, the icon has a red
background.
We have also removed the list of links below a post with the flag
status. A reviewer is meant to click the number beside the flag icon to
view the flags. As a consequence of losing those links, we've removed
the ability to undo or ignore flags below a post.
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.
This commit fixes the follow quality issue with `PostSearchData#raw_data`:
1. URLs are being tokenized and links with similar href and characters
are being duplicated in the raw data.
`Post#cooked`:
```
<p><a href=\"https://meta.discourse.org/some.png\" class=\"onebox\" target=\"_blank\" rel=\"nofollow noopener\">https://meta.discourse.org/some.png</a></p>
```
`PostSearchData#raw_data` Before:
```
This is a test topic 0 Uncategorized https://meta.discourse.org/some.png discourse org/some png https://meta.discourse.org/some.png discourse org/some png
```
`PostSearchData#raw_data` After:
```
This is a test topic 0 Uncategorized https://meta.discourse.org/some.png meta discourse org
```
2. Ligthbox being included in search pollutes the
`PostSearchData#raw_data` unncessarily.
From 28 March 2018 to 28 March 2019, searches for the term `image` on
`meta.discourse.org` had a click through rate of 2.1%. Non-lightboxed images are not included in indexing for search yet we were indexing content within a lightbox. Also, search for terms like `image` was affected we were using `Pasted image` as the filename for
uploads that were pasted.
`Post#cooked`
```
<p>Let me see how I can fix this image<br>\n<div class=\"lightbox-wrapper\"><a class=\"lightbox\" href=\"https://meta.discourse.org/some.png\" title=\"some.png\" rel=\"nofollow noopener\"><img src=\"https://meta.discourse.org/some.png\" width=\"275\" height=\"299\"><div class=\"meta\">\n<svg class=\"fa d-icon d-icon-far-image svg-icon\" aria-hidden=\"true\"><use xlink:href=\"#far-image\"></use></svg><span class=\"filename\">some.png</span><span class=\"informations\">1750×2000</span><svg class=\"fa d-icon d-icon-discourse-expand svg-icon\" aria-hidden=\"true\"><use xlink:href=\"#discourse-expand\"></use></svg>\n</div></a></div></p>

In terms of indexing performance, we now have to parse the given HTML
through nokogiri twice. However performance is not a huge worry here since a string length of 194170 takes only 30ms
to scrub plus the indexing takes place in a background job.
Includes support for flags, reviewable users and queued posts, with REST API
backwards compatibility.

- Notices are visible only by poster and trust level 2+ users.
- Notices are not generated for non-human or staged users.
- Notices are deleted when post is deleted.
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 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.
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.
