### General Changes and Duplication
* We now consider a post `with_secure_media?` if it is in a read-restricted category.
* When uploading we now set an upload's secure status straight away.
* When uploading if `SiteSetting.secure_media` is enabled, we do not check to see if the upload already exists using the `sha1` digest of the upload. The `sha1` column of the upload is filled with a `SecureRandom.hex(20)` value which is the same length as `Upload::SHA1_LENGTH`. The `original_sha1` column is filled with the _real_ sha1 digest of the file.
* Whether an upload `should_be_secure?` is now determined by whether the `access_control_post` is `with_secure_media?` (if there is no access control post then we leave the secure status as is).
* When serializing the upload, we now cook the URL if the upload is secure. This is so it shows up correctly in the composer preview, because we set secure status on upload.
### Viewing Secure Media
* The secure-media-upload URL will take the post that the upload is attached to into account via `Guardian.can_see?` for access permissions
* If there is no `access_control_post` then we just deliver the media. This should be a rare occurrance and shouldn't cause issues as the `access_control_post` is set when `link_post_uploads` is called via `CookedPostProcessor`
### Removed
We no longer do any of these because we do not reuse uploads by sha1 if secure media is enabled.
* We no longer have a way to prevent cross-posting of a secure upload from a private context to a public context.
* We no longer have to set `secure: false` for uploads when uploading for a theme component.
This ensures that the user object is created fresh for each example.
This is required for this particular spec as we can not risk having a stale
object, which can lead to a flaky spec.
People rarely want to have their avatars show up as the preview image on social media platforms. Instead, we should fall back to the site opengraph image.
It used to check how many quotes were inside a post, without taking
considering that some quotes can contain other quotes. This commit
selects only top level quotes.
I had to use XPath because I could not find an equivalent CSS
selector.
Meta thread: https://meta.discourse.org/t/sending-a-pm-with-the-following-title-causes-an-error/135654/3
We had an issue where if someone sent a PM with crazy
characters that are stripped and we end up with only
a number, the topic redirect errored because the slug was
a number. so instead we return the default as well if
the slug is a number after prettification
The ROTP gem is only used in a very small amount of places in the app, we don't need to globally require it.
Also set the Addressable gem to not have a specific version range, as it has not been a problem yet.
Some slight refactoring of UserSecondFactor here too to use SecondFactorManager to avoid code repetition
This is a slight workaround which helps somewhat now but is pending a larger
fix.
When this spec ran in parallel mode uploads could start cross talking and
an upload you expect to be there may vanish.
This works around the issue by making the upload unique every time it is
created
It also folds up an expensive test into the main one.
* DEV: Add API to alter uploads Markdown
* DEV: Extract data attributes from image / download Markdown
For example '[test|attachment|hello=world]' will generate an 'a' element
with a data attribute: 'data-hello=world'.
This commit also makes MarkdownIt to transform '|attachment' into
'class="attachment"'. This transformation used to be a part of the
process which resolves short URLs (i.e. upload://).
* DEV: Export imageNameFromFileName
Non UTF-8 user_agent requests were bypassing logging due to PG always
wanting UTF-8 strings.
This adds some conversion to ensure we are always dealing with UTF-8
This fixes the following issues:
* The link element on the lightbox which pops open the lightbox was linking to the S3 URL with a private ACL instead of the secure media URL for the image
* Change to use `@post.with_secure_media?` in `CookedPostProcessor` for URL cooking, as in some cases, like when a post is edited and an upload is added, `upload.secure?` can be false which resulted in `srcset` URLs not being cooked correctly to secure media upload urls.
This feature adds the ability to define synonyms for tags, and the ability to merge one tag into another while keeping it as a synonym. For example, tags named "js" and "java-script" can be synonyms of "javascript". When searching and creating topics using synonyms, they will be mapped to the base tag.
Along with this change is a new UI found on each tag's page (for example, `/tags/javascript`) where more information about the tag can be shown. It will list the synonyms, which categories it's restricted to (if any), and which tag groups it belongs to (if tag group names are public on the `/tags` page by enabling the "tags listed by group" setting). Staff users will be able to manage tags in this UI, merge tags, and add/remove synonyms.
This bug was causing some unusual behavior when the last post is filtered (e.g. from an ignored user). In some situations this would cause suggested topics to be omitted from the payload.
The next_page specs have been updated to remove most of the stubs
* FEATURE: Ability to add components to all themes
This is the first and functional step from that topic https://dev.discourse.org/t/adding-a-theme-component-is-too-much-work/15398/16
The idea here is that when a new component is added, the user can easily assign it to all themes (parents).
To achieve that, I needed to change a site-setting component to accept `setDefaultValues` action and `setDefaultValuesLabel` translated label.
Also, I needed to add `allowAny` option to disable that for theme selector.
I also refactored backend to accept both parent and child ids with one method to avoid duplication (Renamed `add_child_theme!` to more general `add_relative_theme!`)
* FIX: Improvement after code review
* FIX: Improvement after code review2
* FIX: use mapBy and filterBy directly
We already cache failed onebox URL requests client-side, we now want to cache this on the server-side for extra protection. failed onebox previews will be cached for 1 hour, and any more requests for that URL will fail with a 404 status. Forcing a rebake via the Rebake HTML action will delete the failed URL cache (like how the oneboxer preview cache is deleted).
If a user has more than 60 active sessions, the oldest sessions will be terminated automatically. This protects performance when logging in and when loading the list of recently used devices.
This is a bottom up rewrite of Discourse cache to support faster performance
and a limited surface area.
ActiveSupport::Cache::Store accepts many options we do not use, this partial
implementation only picks the bits out that we do use and want to support.
Additionally params are named which avoids typos such as "expires_at" vs "expires_in"
This also moves a few spots in Discourse to use Discourse.cache over setex
Performance of setex and Discourse.cache.write is similar.
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
PG 12 changes internals in a subtle way, time jitter is noticed in a few new
spots (which is normal) and default ordering is a bit different which is meant
to be random anyway.
There was an issue on dev where when uploading secure media, the href of the media was correctly being replaced in the CookedPostProcessor, but the srcset urls were not being replaced correctly. This is because UrlHelper.cook_url was returning the asset host URL for the media for secure media instead of returning early with the proxied secure proxy url.
In non-login-required sites, we prevent secure uploads already used in PMs from being used in public topics.
In login_required sites, secure uploads should be reusable in any topic, PM or not.
Previously our custom exception handler was unable to handle situations
where an invalid mime type was sent, resulting in a warning log
This ensures we pretend a request is HTML for the purpose of rendering
the error page if an invalid mime type from a scanner is shipped to the app
