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.
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.
* Remove _calculateTopOffset entirely
* Show group card with animated loading state
Showing the animated loading state before rending the actual content prevents an
awkward scroll position jump when displaying this card.
This mimics the behaviour of the user card (which uses the same `CardContentsBase` mixin).
* Fix two user card issues
1. A JS console error (with no consequences) when clicking a group mention
2. User cards weren't being loaded from the header (for example, for PMs)

* FEATURE: display warning when sharing a topic in a restricted category
If a topic belongs to a category that is not readable by everyone, display a text warning of "Only visible to members of groups: [group_a], [group_b]"
* DEV: Adding a new category means we need to bump this value
* DEV: pass category to showModal
`d-modal-body.js` was setting the text of a `modal-alert` element to `""`, but not removing any classes on that element. Changing this to call `_clearFlash()` ensures that a variety of styling classes are also removed from the element, which prevents empty alert elements being included on any subsequent modals that are displayed.
Several other controllers have also been modified to change the class of the error from `alert-error` to `error. The `alert-` is unnecessary, as it is added by `_flash(msg)` within `d-modal-body.js`.
* FIX: ensure required_tag_group_name is null if no value present
If the array was present but empty `required_tag_group_name` would be set to undefined, which would then be removed from the payload of the remote request.
Addming the length check ensures the value is set to null, which is sent as an empty value (which the backend sees, and can remove it and persist the change on the Category object).
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
If the initial `get`/`head` response within `resolve` returns a status code of `103`, attempt to fetch the same URL with the alternative `small_get` method.
* FIX: allowed_theme_ids should not be persisted in GlobalSettings
It was observed that the memoized value of `GlobalSetting.allowed_theme_ids` would be persisted across requests, which could lead to unpredictable/undesired behaviours in a multisite environment.
This change moves that logic out of GlobalSettings so that the returned theme IDs are correct for the current site.
Uses get_set_cache, which ultimately uses DistributedCache, which will take care of multisite issues for us.
When a post is flagged with the reason of 'Something Else' a brief message can be added by the user which subsequently creates a `meta_topic` private message. The group `moderators` is automatically added to this topic.
If category group moderation is enabled, and the post belongs to a category with a reviewable group, that group should also be added to the meta_topic.
Note: This extends the `notify_moderators` logic, and will add the reviewable group to the meta_topic, regardless of the settings of that group.
* 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.
Not specifying an `Accept-Language` should be equivalent to specifying an `Accept-Language` of `*`, however some webservers seem to prefer it if we are explicit about being able to handle a response of content in any language.
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).
* UX: Remove background image after image has loaded
If an image has a `smallUpload`, that may be set as the `background-image` on the `img` element, and the `img` element set to use `lazy` loading. When the browser decides to load the `src` of the image element, it is rendered on top of the existing background image.
However, if the image proper has a transparent background, the background image may be partially visible through the transparent portions of the image.
This change creates an `onload` event that removes the background image when the image proper has completed loading.
We want to put the name of the trust level in to generated URLs, not the human-readable form.
i.e.:
`/admin/users/list/newuser`
rather than:
`/admin/users/list/new user`
* FIX: Allow SVG uploads if dimensions are a fraction of a unit
`UploadCreator` counts the number of pixels in an file to determine if it is valid. `pixels` is calculated by multiplying the width and height of the image, as determined by FastImage.
SVG files can have their width/height expressed in a variety of different units of measurement. For example, ‘px’, ‘in’, ‘cm’, ‘mm’, ‘pt’, ‘pc’, etc are all valid within SVG files. If an image has a width of `0.5in`, FastImage may interpret this as being a width of `0`, meaning it will report the `size` as being `0`.
However, we don’t need to concern ourselves with the number of ‘pixels’ in a SVG files, as that is irrelevant for this file format, so we can skip over the check for `pixels == 0` when processing this file type.
* DEV: Speed up getting SVG dimensions
The `-ping` flag prevents the entire image from being rasterized before a result is returned. See:
https://imagemagick.org/script/command-line-options.php#ping
* 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
Rather than returning the size of the currently rendered image in the composer window (which is dependent on browser settings such as window size and zoom level), return the actual dimensions of the image file itself.
(Also see commit 50293b590e which was an earlier attempt to fix this by excluding Oneboxed images entirely. That was reverted as the CSS selector didn’t work on all browsers.)
* FIX: Ignore `allowlistgeneric` Onebox image sizes
The size of an image contained within the preview pane of a Composer window may vary depending on the configuration of the browser displaying the Composer (e.g., dimension of browser window, zoom level, etc.).
Presently, the dimensions of the images from the browser creating the post containing the Onebox will be used to render the Onebox to anyone who views the post. It is safer to let the backend figure out the dimensions of the images. Therefore, exclude `.onebox.allowlistedgeneric` images from the list of `image_sizes` sent to the backend.
* DEV: Replace jQuery selector with pure JS
* DEV: remove more jQuery
* 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.
* Update lib/onebox/engine/amazon_onebox.rb

* DEV: Allow wildcards in Oneboxer optional domain Site Settings
Allows a wildcard to be used as a subdomain on Oneboxer-related SiteSettings, e.g.:
- `force_get_hosts`
- `cache_onebox_response_body_domains`
- `force_custom_user_agent_hosts`
* DEV: fix typos
* FIX: Try doing a GET after receiving a 500 error from a HEAD
By default we try to do a `HEAD` requests. If this results in a 500 error response, we should try to do a `GET`
* DEV: `force_get_hosts` should be a hidden setting
* DEV: Oneboxer Strategies
Have an alternative oneboxing ‘strategy’ (i.e., set of options) to use when an attempt to generate a Onebox fails. Keep track of any non-default strategies that were used on a particular host, and use that strategy for that host in the future.
Initially, the alternate strategy (`force_get_and_ua`) forces the FinalDestination step of Oneboxing to do a `GET` rather than `HEAD`, and forces a custom user agent.
* DEV: change stubbed return code
The stubbed status code needs to be a value not recognized by FinalDestination
* FEATURE: Cache successful HTTP GET requests during Oneboxing
Some oneboxes may fail if when making excessive and/or odd requests against the target domains. This change provides a simple mechanism to cache the results of succesful GET requests as part of the oneboxing process, with the goal of reducing repeated requests and ultimately improving the rate of successful oneboxing.
To enable:
Set `SiteSetting.cache_onebox_response_body` to `true`
Add the domains you’re interesting in caching to `SiteSetting. cache_onebox_response_body_domains` e.g. `example.com|example.org|example.net`
Optionally set `SiteSetting.cache_onebox_user_agent` to a user agent string of your choice to use when making requests against domains in the above list.
* FIX: Swap order of duration and value in redis call
The correct order for `setex` arguments is `key`, `duration`, and `value`.
Duration and value had been flipped, however the code would not have thrown an error because we were caching the value of `1.day.to_i` for a period of 1 seconds… The intention appears to be to set a value of 1 (purely as a flag) for a period of 1 day.
It has been observed that doing a HEAD against an Amazon store URL may result in a 405 error being returned.
Skipping the HEAD request may result in an improved oneboxing experience when requesting these URLs.
* FEATURE: allow category group moderators to pin/unpin topics
Category group moderators should be able to pin/unpin any topics within a category where they have appropraite category group moderator permissions.
SVG files can have dimensions expressed in inches, centimeters, etc., which may lead to the dimensions being misinterpreted (e.g. “8in” ends up as 8 pixels).
If the file type is `svg`, ask ImageMagick to work out what size the SVG file should be rendered on screen.
NOTE: The `pencil.svg` file was obtained from https://freesvg.org/1534028868, which has placed the file in to the public domain.
`Onebox.preview` can return 0-to-n errors, where the errors are missing OpenGraph attributes (e.g. title, description, image, etc.). If any of these attributes are missing, we construct an error message and attach it to the Oneboxer preview HTML. The error message is something like:
“Sorry, we were unable to generate a preview for this web page, because the following oEmbed / OpenGraph tags could not be found: description, image”
However, if the only missing tag is `image` we don’t need to display the error, as we have enough other data (title, description, etc.) to construct a useful/complete Onebox.
NewPostManager’s `post_needs_approval_in_its_category` method should allow category group moderators to create topics/reply to topics that where they have appropraite permissions.
(ie, if a user has permission to moderate a post, any posts made by them shouldn’t be sent to moderation)
`convert_to_jpeg!` is only called if `convert_png_to_jpeg?` and/or `should_alter_quality?` is true.
`convert_png_to_jpeg?` can be disabled by setting `SiteSetting.png_to_jpg_quality` to 100.
However, `should_alter_quality?` could be true if `SiteSetting.recompress_original_jpg_quality` was lower than the quality of the uploaded file, regardless of file type.
This commits changes `should_alter_quality?` so that uploaded png files will use the `SiteSetting.png_to_jpg_quality` value, rather than ``SiteSetting.recompress_original_jpg_quality` value.
* DEV: TopicTrackingState calls should happen in the background
It was observed that calling TopicTrackingState on popular topics could result in a large number of calls to redis, resulting in slow response times when posting replies.
These calls should be moved to a background job.
* DEV: PostUpdateTopicTrackingState should execute on default queue
* FEATURE: Allow categroy group moderators to list/unlist topics
If enabled via SiteSettings, a user belonging to a group which has been granted category group moderator privileges should be able to list/unlist topics belonging to the appropraite category.
* DEV: More robust processing of URLs
The previous `UrlHelper.encode_component(CGI.unescapeHTML(UrlHelper.unencode(uri))` method would naively process URLs, which could result in a badly formed response.
`Addressable::URI.normalized_encode(uri)` appears to deal with these edge-cases in a more robust way.
* DEV: onebox should use UrlHelper
* DEV: fix spec
* DEV: Escape output when rendering local links
* FEATURE: Allow Category Group Moderators to edit topic titles
Adds category group moderators to the topic guardian’s `can_edit` method.
The value of `can_edit` is returned by the topic view serializer, and this value determines whether the current user can edit the title/category/tags of the topic directly (which category group moderators could already do by editing the first post of a topic).
Note that the value of `can_edit` is now always returned by the topic view serializer (ie, for both true and false values) to cover the case where a topic is moved out of a category that a category group moderator has permissions on, so that when the topic is reloaded the UI picks up that `can_edit` is now false, and thus the edit icon should no longer be displayed.
* DEV: Add a comment explaining why `can_edit` is always returned
* 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.

`setPermissionsGroups` would initialize an empty permissions object whenever new groups were added to the Tag Group. This meant that if you selected the `visible` permission and then added groups to the Tag Group, the `visible` permission would be obliterated and the Tag Group would be treated as though it was `private`.
* FEATURE - allow category group moderators to delete topics
* Allow individual posts to be deleted
* DEV - refactor for new `can_moderate_topic?` method
* FEATURE - Add SiteSettings to control JPEG image quality
`recompress_original_jpg_quality` - the maximum quality of a newly
uploaded file.
`image_preview_jpg_quality` - the maximum quality of OptimizedImages
* FEATURE: allow category group moderators to edit posts
If the `enable_category_group_moderation` SiteSetting is enabled, posts should be editable by those belonging to the appropraite groups.
* FIX: allow editing in composer before a category is selected
If the site setting `allow_uncategorized_topics` is disabled, but no site categories have a topic template, the textarea of the composer should be enabled. This allows for a post body to be entered, however the post/topic should not be successfully created until a category is selected.
If `allow_uncategorized_topics` is disabled *and* one or more categories have a topic template, the textarea of the composer should remain disabled until a category is chosen (so that the body of their post isn’t overwritten by the template).
* Avoid recalculating hasTopicTemplates repeatedly
