Régis Hanol 860deeb072 FIX: identify slug-less topic urls everywhere
In 91c89df6, I fixed the onebox to support local topics with a slug-less URL.
This commit fixes all the other spots (search, topic links and user badges) where we look up for a local topic.

PERF: avoid race conditions when creating topic links
Previously the code was very race condition prone leading to
odd failures in production

It was re-written in raw SQL to avoid conditions where rows
conflict on inserts

There is no clean way in ActiveRecord to do:

Insert, on conflict do nothing and return existing id.

This also increases test coverage, we were previously not testing
the code responsible for crawling external sites directly

Robin Ward 088c11a12c FIX: Don't raise an exception if a TopicLink cannot be created
This can happen under concurrency and it's fine. If a `TopicLink`
already exists we can continue on without raising an error.

DEV: stop freezing frozen strings
We have the `# frozen_string_literal: true` comment on all our
files. This means all string literals are frozen. There is no need
to call #freeze on any literals.

For files with `# frozen_string_literal: true`

```
puts %w{a b}[0].frozen?
=> true

puts "hi".frozen?
=> true

puts "a #{1} b".frozen?
=> true

puts ("a " + "b").frozen?
=> false

puts (-("a " + "b")).frozen?
=> true
```

FIX: inbound link when the only slug available (#8457)
Problem mentioned in [meta](https://meta.discourse.org/t/inbound-links-dont-show-up-when-topic-id-is-not-included/100551)

When there is an internal link without ID, only slug, we should still try to create reflection link.

Penar Musaraj 102909edb3 FEATURE: Add support for secure media (#7888)
This PR introduces a new secure media setting. When enabled, it prevent unathorized access to media uploads (files of type image, video and audio). When the `login_required` setting is enabled, then all media uploads will be protected from unauthorized (anonymous) access. When `login_required`is disabled, only media in private messages will be protected from unauthorized access. 

A few notes: 

- the `prevent_anons_from_downloading_files` setting no longer applies to audio and video uploads
- the `secure_media` setting can only be enabled if S3 uploads are already enabled and configured
- upload records have a new column, `secure`, which is a boolean `true/false` of the upload's secure status
- when creating a public post with an upload that has already been uploaded and is marked as secure, the post creator will raise an error
- when enabling or disabling the setting on a site with existing uploads, the rake task `uploads:ensure_correct_acl` should be used to update all uploads' secure status and their ACL on S3

Krzysztof Kotlarek 427d54b2b0 DEV: Upgrading Discourse to Zeitwerk (#8098)
Zeitwerk simplifies working with dependencies in dev and makes it easier reloading class chains. 

We no longer need to use Rails "require_dependency" anywhere and instead can just use standard 
Ruby patterns to require files.

This is a far reaching change and we expect some followups here.

Sam Saffron 30990006a9 DEV: enable frozen string literal on all files
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

Arpit Jalan d1597683f3 Revert "FIX: trim trailing slash from topic links"
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.

David Taylor 37249c9a32 FIX: Do not reset link counts when post is rebaked
This was an indentation mistake introduced in 44eba0b. Pretty understandable, considering we are indented 8 levels deep in this method. Will follow-up with a refactor to improve this.

Guo Xiang Tan 44eba0bb60 FIX: Don't rescue `PG::UniqueViolation` within a transaction.
Also acquire a transaction per link instead of failing when
any of the links can't be processed.

This prevents ActiveRecord from rolling back the transaction
and the next SQL statement sent to PG will fail. This is
however hard to test as it only happens when there are
two competing process trying to process this method at the
same time.

Sam 5f64fd0a21 DEV: remove exec_sql and replace with mini_sql
Introduce new patterns for direct sql that are safe and fast.

MiniSql is not prone to memory bloat that can happen with direct PG usage.
It also has an extremely fast materializer and very a convenient API

- DB.exec(sql, *params) => runs sql returns row count
- DB.query(sql, *params) => runs sql returns usable objects (not a hash)
- DB.query_hash(sql, *params) => runs sql returns an array of hashes
- DB.query_single(sql, *params) => runs sql and returns a flat one dimensional array
- DB.build(sql) => returns a sql builder

Guo Xiang Tan 142571bba0 Remove use of `rescue nil`.
* `rescue nil` is a really bad pattern to use in our code base.
  We should rescue errors that we expect the code to throw and
  not rescue everything because we're unsure of what errors the
  code would throw. This would reduce the amount of pain we face
  when debugging why something isn't working as expexted. I've
  been bitten countless of times by errors being swallowed as a
  result during debugging sessions.
