When loading posts in a topic, the topic level guardian
checks are run multiple times even though all the posts belong to the
same topic. Profiling in production revealed that this accounted for a
significant amount of request time for a user that is not staff or anon.
Therefore, we're optimizing this by adding memoizing the topic level
calls in `PostGuardian`. Speficifally, the result of
`TopicGuardian#can_see_topic?` and `PostGuardian#can_create_post?`
method calls are memoized per topic.
Locally profiling shows a significant improvement for normal users
loading a topic with 100 posts.
Benchmark script command: `ruby script/bench.rb --unicorn --skip-bundle-assets --iterations 100`
Before:
```
topic user:
50: 114
75: 117
90: 122
99: 209
topic.json user:
50: 67
75: 69
90: 72
99: 162
```
After:
```
topic user:
50: 101
75: 104
90: 107
99: 184
topic.json user:
50: 53
75: 53
90: 56
99: 138

This commit removes 3 redundant DB queries when loading posts.
1. `@posts` will eventually have to be loaded so we can avoid two
additional queries.
2. No need to preload topic association of posts as we're already
dealing with a fixed topic in `TopicView`.
This PR removes the limit added to max_users_notified_per_group_mention during #19034 and improve the performance when expanding mentions for large channel or groups by removing some N+1 queries and making the whole process async.
* Fully async chat message notifications
* Remove mention setting limit and get rid of N+1 queries
It should fix flakeys we have due to using_session. This commit is also fixing tests which were failing constantly with treadsafe enabled.
A test has also bene skipped as the issue couldn't be found so far.

NGINX v1.23 concatenates duplicate headers into a single comma-separated string. We were doing an equality check on `x-forwarded-proto`. If the request includes multiple `x-forwarded-proto` headers then this check would fail under NGINX v1.23, and our config assumed an `http` connection.
This commit updates the config to check for `https` at the end of the header, thereby restoring the old behavior when multiple `x-forwarded-proto` request headers are sent.
In some situations (e.g. disaster recovery), it may make sense to spin up a temporary readonly version of a cluster. In that situation, the s3 `expire_missing_assets` job would delete assets which are still in use by the canonical read-write version of the cluster.
To avoid that, this commit will skip deletion if the site is currently in readonly mode.
We provide a `.ruby-version.sample` file that we use for warning developers
about the minimum recommended Ruby version to run Discourse.
d24dfe8f96/config/application.rb (L15-L20)
But if people copy the sample to a `.ruby-version` file it would be added
next time they commit.
This adds the `.ruby-version` file to `.gitignore` so it doesn't get commited
by mistake and developers can test Discourse on other versions of Ruby if
they want to.
1. Fix bug where we were not waiting for all unicorn workers to start up
before running benchmarks.
2. Fix a bug where headers were not used when benchmarking. Admin
benchmarks were basically running as anon user.
3. Disable rate limits when in profile env. We're pretty much going to
hit the rate limit every time as a normal user.
4. Benchmark against topic with a fixed posts count of 100. Previously profiling script was just randomly creating posts
and we would benchmark against a topic with a fixed posts count of 30.
Sometimes, the script fails because no topics with a posts count of 30
exists.
5. Benchmarks are not run against a normal user on top of anon and
admin.
6. Add script option to select tests that should be run.
# Context
When a topic is reviewable by a group we give those group moderators some admin abilities including the ability to delete a topic.
# Problem
There are two main problems:
1. Currently when a group moderator deletes a topic they are redirected to root (not the same for staff)
2. Viewing the categories deleted topics (`c/foo/1/?status=deleted`) does not display the deleted topic to the group moderator (not the same for staff).
# Fix
If the `deleted_by` user is part a group that matches the `reviewable_by_group` on a topic then don't redirect. This is the default interaction for staff to give them the ability to do things like restore the topic in case it was accidentally deleted.
To render the deleted topics as expected for the group moderator I am utilizing [the guardian scope of `guardian.can_see_deleted_topics?` for said category](https://github.com/discourse/discourse/pull/19618/files#diff-288e61b8bacdb29d9c2e05b42da6837b0036dcf1867332d977ca7c5e74a44297R802-R803)
- improves UI by displaying channel status on it's own line
- ensures channel status is correctly updated right after the request on frontend
- adds status on info page
We show live user status on mentions starting from a76d864. But status didn’t appear on the post that appears on the bottom of the topic just after a user posted it (status appeared only after page reloading). This adds status to just posted posts.
We need to set the local state of a channel before performing any async operations. Otherwise, multiple leave/join calls can race against each other and cause the local state to get out-of-sync with the server.

Previously, browser logs would be printed to STDOUT halfway through the test run. This commit changes the behaviour so that the logs are included in the failure summary along with other rspec failure information.
There is an issue where chat message processing breaks due to
unhandles `SocketError` exceptions originating in the SSRF check,
specifically in `FinalDestination::Resolver`.
This change gives `FinalDestination::SSRFDetector` a new error class
to wrap the `SocketError` in, and haves the `RetrieveTitle` class
handle that error gracefully.
Currently the `turbo:spec` task will fail when encountering system
tests as Capypara tries to use the same port for each process.
This simple change uses the same strategy as for databases, by just
incrementing the port number by `TEST_ENV_NUMBER` for each process.
Instead of relying on the `ILIKE` operator to filter out image links, we
can instead rely on the `TopicLink#extension` column which allows us to
more efficiently filter out image links.
This optimization mainly affects topics that are link heavy which is
common in topics with alot of replies. When profiling a production
instance for a topic with 10K replies and 2.5K `topic_links`, this
optimization reduces the query time from ~18ms to around ~4ms.
