Some product pages on Amazon are using a new HTML structure, meaning the previous Onebox engine was unable to gather the price and/or description. This change should allow these pages to be Oneboxed.
This allows text editors to use correct syntax coloring for the heredoc sections.
Heredoc tag names we use:
languages: SQL, JS, RUBY, LUA, HTML, CSS, SCSS, SH, HBS, XML, YAML/YML, MF, ICS
other: MD, TEXT/TXT, RAW, EMAIL
In an earlier PR, we decided that we only want to block a domain if
the blocked domain in the SiteSetting is the final destination (/t/59305). That
PR used `FinalDestination#get`. `resolve` however is used several places
but blocks domains along the redirect chain when certain options are provided.
This commit changes the default options for `resolve` to not do that. Existing
users of `FinalDestination#resolve` are
- `Oneboxer#external_onebox`
- our onebox helper `fetch_html_doc`, which is used in amazon, standard embed
and youtube
- these folks already go through `Oneboxer#external_onebox` which already
blocks correctly
If the SiteSetting `allowed_onebox_iframes` contains a value of `*`, it will use the values of `all_iframe_origins` during the Oneboxing process. If `all_iframe_origins` itself contains a value of `*`, `origins_to_regexes` will try to return a "catch-all" regex.
Other code assumes `origins_to_regexes`will return an array, so this change ensures the `*` case will return an array containing only the catch-all regex.
1. `html_doc.css('.Box.md')` always returns a truthy value (e.g. `[]`) so the second branch of the if-elsif never ran
2. `node&.css('text()')` was invalid code that would raise an error
3. Matching on h3 elements is no longer correct with the current html structure returned by GitHub
When attempting to Onebox a page if there is no `meta property="og:description"` tag but there is a `meta name="description"` tag, Onebox should try to use that value.
We are no longer able to display the image returned by Instagram directly within a Discourse site (either in the composer, or within a cooked post within a topic), so:
- Display an image placeholder in the composer preview
- A cooked post should use an iframe to display the Instagram 'embed' content
Sections with unreserverd characters will appear url-encoded and need to
be unescaped before using it.
Wikipedia generates 2 different spans in this case in the same page, one
with an id resulting of replacing the % symbols with . and the other with
the decoded version of the string. For example, for /wiki/foo#A%C3%A1A it
will generate:
<span id="A.C3.A1A"></span>
<span id="AáA">AáA</span>
Unescaping the `m_url_hash_name` should work in all cases to target the
proper section span.
* FEATURE: Onebox can match engines based on the content_type
`FinalDestination` now returns the `content_type` of a resolved URL.
`Oneboxer` passes this value to `Onebox` itself. Onebox engines can now specify a `matches_content_type` regex of content_types that the engine can handle, regardless of the URL.
`ImageOnebox` will match URLs with a content type of `image/png`, `jpg`, `gif`, `bmp`, `tif`, etc.
This will allow images that exist at a URL without a file type extension to be correctly rendered, assuming a valid `content_type` is returned.
By default, Twitter will return the URL for the avatar image of the tweet poster as the `og:image` value.
However, if the `user_generated` attribute is true, we should not use this as the avatar URL as this will be an URL of an image in the tweet itself (e.g., an image belonging to a tweeted news story).
* 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
IMDb movie links were being rendered as posters. This was because
IMDb was sending `og:type` as `image` randomly in some cases. To
fix this we'll now default all IMDb links as article type. This will
ensure that the IMDb onebox link includes all the information instead
of showing just a poster without any context.
* FIX: return an empty result if response from Amazon is missing attributes
Check we have the basic attributes requires to construct a Onebox for Amazon.
This is an attempt to handle scenarios where we receive a valid 200-status response from an Amazon request that does not include the data we’re expecting.

* 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.

Uses discourse/onebox@ff9ec90
Adds a hidden site setting called disable_onebox_media_download_controls which will add controlslist="nodownload" to video and audio oneboxes, and also to the local video and audio oneboxes within Discourse.
* FEATURE: onebox for local categories
This commit adjusts the category onebox to look more like the category boxes do on the category page.

* 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 commit adds a new site setting "allowed_onebox_iframes". By default, all onebox iframes are allowed. When the list of domains is restricted, Onebox will automatically skip engines which require those domains, and use a fallback engine.
