Ruby 2.7 or earlier `+contents` returns self.dup
when `frozen_string_literal: true`. However, Ruby 3.0 returns self
because this string is interpolated one, which is not frozen anymore.
This commit uses self.dup to return duplicated string regardless Ruby
versions.

FinalDestination now supports the `follow_canonical` option, which will perform an initial GET request, parse the canonical link if present, and perform a HEAD request to it.
We use this mode during embeds to avoid treating URLs with different query parameters as different topics.
DEV: Allow passing cook_method to TopicEmbed.import to override default
This will be used in the rss-polling plugin when we want to have
oneboxes on feed content, like youtube for example.
Over the years we accrued many spelling mistakes in the code base.
This PR attempts to fix spelling mistakes and typos in all areas of the code that are extremely safe to change
- comments
- test descriptions
- other low risk areas
If the associated page of a remote url passed to `TopicEmber.new(remote_url)` contained a malformed link like: `<a href="(http://foo.bar)">Baz</a>` it would raise an uncaught exception:
```
Job exception: Invalid scheme format: (http
```
This reverts commit 20780a1eee.
* SECURITY: re-adds accidentally reverted commit:
03d26cd6: ensure embed_url contains valid http(s) uri
* when the merge commit e62a85cf was reverted, git chose the 2660c2e2 parent to land on
instead of the 03d26cd6 parent (which contains security fixes)
Discourse.cache is a more consistent method to use and offers clean fallback
if you are skipping redis
This is part of a larger change that both optimizes Discoruse.cache and omits
use of setex on $redis in favor of consistently using discourse cache
Bench does reveal that use of Rails.cache and Discourse.cache is 1.25x slower
than redis.setex / get so a re-implementation will follow prior to porting
Doing .pluck(:column).first is a very common pattern in Discourse and in
most cases, a limit cause isn't being added. Instead of adding a limit
clause to all these callsites, this commit adds two new methods to
ActiveRecord::Relation:
pluck_first, equivalent to limit(1).pluck(*columns).first
and pluck_first! which, like other finder methods, raises an exception
when no record is found
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.
When `SiteSetting.embed_truncate` is enabled (by default), the truncated
string is mutatable and does not raise an error.
However, when the setting is disabled, the `contents` string is frozen
and immutable, and will raise a `FrozenError`.
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
