Prior to this fix we would output an image with no width/height which would then bypass a large part of `CookedProcessorMixin` and have no aspect ratio. As a result, an image with no size would cause layout shift.
It also removes a fix for oneboxes in chat messages due to this case.
Wikimedia provides a thumbnail url for its images, so we should use that
for oneboxes instead of the full-size image. Because the size of the
onebox image we display is quite small anyways the thumbnail wikimedia
provides should suffice and will save bandwidth.

Currently when generating a onebox for Discourse topics, some important
context is missing such as categories and tags.
This patch addresses this issue by introducing a new onebox engine
dedicated to display this information when available. Indeed to get this
new information, categories and tags are exposed in the topic metadata
as opengraph tags.
Linking a commit from a GitHub pull request included the complete commit
message, instead of just the first line. The rest of the commit message
will be added to the body of the Onebox.
* FIX: Fix a bug that is accessing the values in a hash wrongly and write tests
I decided to write tests in order to be confident in my refactor that's in the next commit.
Meanwhile I have discovered a potential bug. The `title_attr` key was accessed as a string,
but all the keys are actually symbols so it was never evaluated to be true.
irb(main):025:0> d = {key: 'value'}
=> {:key=>"value"}
irb(main):026:0> d['key']
=> nil
irb(main):027:0> d[:key]
=> "value"
* DEV: Extract methods for readability
I will be adding a new method following the conventions in place for adding a new normalizer. And this will make the readability of the `raw` block even more difficult; so I am extracting self contained private methods beforehand.
* FEATURE: Parse JSON-LD and introduce Movie object
JSON LD data is very easily transferable to Ruby objects because they contain types. If these types are mapped to Ruby objects, it is also better to make all the parsed data very explicit and easily extendable.
JSON-LD has many more standardized item types, with a full list here: https://schema.org/docs/full.html
However in order to decrease the scope, I only adapted the movie type.
* DEV: Change inheritance between normalizers
Normalizers are not supposed to have an inheritance relationships amongst each other. They are all normalizers, but all normalizing separate protocols. This is why I chose to extract a parent class and relieve Open Graph off that responsibility. Removing the parent class altogether could also a possibility, but I am keeping the scope limited to having a more accurate representation of the normalizers while making it easier to add a new one.
* Lint changes
* Bring back the Oembed OpenGraph inheritance
There is one test that caught that this inheritance was necessary. I still think modelling wise this inheritance shouldn't exist, but this can be tackled separately.
* Return empty hash if the json received is invalid
Before this change if there was a parsing error with JSON it would throw an exception. The goal of this commit is to rescue that exception and then log a warning. I chose to use Discourse's logger wrapper `warn_exception` to have the backtrace and not just used Rails logger. I considered raising an `InvalidParameters` error however if the JSON here is invalid it should not block showing of the Onebox, so logging is enough.
* Prep to support more JSONLD schema types with case
* Extract mustache template object created from JSONLD
* FIX: Quoting Oneboxed content should exclude formatting
When a post is quoted that includes Oneboxed content, we should not include the formatting generated by the Onebox. Rather, we should attempt to collapse the link referenced by the Onebox to a single line text link.
* DEV: fix tests
* FIX: Improve GitHub folder regexp in Onebox
It used to match any GitHub URL that was not matched by the other GitHub
Oneboxes and it did not do a good job at handling those. With this
change, the generic Onebox will handle the remaining URLs.
* FEATURE: Add Onebox for GitHub Actions
* FEATURE: Add Onebox for PR check runs
* FIX: Remove image from GitHub folder Oneboxes
It is a generic, auto-generated image which does not provide any value.
* DEV: Add tests
* FIX: Strip HTML comments from PR body
* Move onebox gem in core library
* Update template file path
* Remove warning for onebox gem caching
* Remove onebox version file

* Remove onebox web specific code
This code was used in standalone onebox Sinatra application
* Merge Discourse specific AllowlistedGenericOnebox engine in core
* Fix onebox engine filenames to match class name casing
* Move onebox specs from gem into core
* DEV: Rename `response` helper to `onebox_response`
Fixes a naming collision.
* Require rails_helper
* Don't use `before/after(:all)`
* Whitespace
* Remove fakeweb
* Remove poor unit tests
* DEV: Re-add fakeweb, plugins are using it

* FIX: Follow additional redirect status codes (#476)
Don’t throw errors if we encounter 303, 307 or 308 HTTP status codes in responses
* Remove an empty file
* DEV: Update the license file
Using the copy from https://choosealicense.com/licenses/gpl-2.0/#
Hopefully this will enable GitHub to show the license UI?
* DEV: Update embedded copyrights
* DEV: Add Onebox copyright notice
* DEV: Add MIT license, convert COPYRIGHT.txt to md

* FEATURE: onebox for local categories
This commit adjusts the category onebox to look more like the category boxes do on the category page.
Co-authored-by: Jordan Vidrine <jordan@jordanvidrine.com>
* FEATURE: display error if Oneboxing fails due to HTTP error
- display warning if onebox URL is unresolvable
- display warning if attributes are missing
* FEATURE: Use new Instagram oEmbed endpoint if access token is configured
Instagram requires an Access Token to access their oEmbed endpoint. The requirements (from https://developers.facebook.com/docs/instagram/oembed/) are as follows:
- a Facebook Developer account, which you can create at developers.facebook.com
- a registered Facebook app
- the oEmbed Product added to the app
- an Access Token
- The Facebook app must be in Live Mode
The generated Access Token, once added to SiteSetting.facebook_app_access_token, will be passed to onebox. Onebox can then use this token to access the oEmbed endpoint to generate a onebox for Instagram.

This pr replaces `{{{ }}}` usage by a {{html-safe}} helper. While it doesn't solve the underlying issue, it gives us a path forward without risking breaking too much existing behavior.
Also introduces an htmlSafe computed macro:
```
import { htmlSafe } from "discourse/lib/computed";
htmlDescription: htmlSafe("description")
```
Overtime {{html-safe}} usage should be removed and moved to components properties or specialized components/helpers.
