Previously you'd get a server side generic error due to a password check
failing. Now the input element has a maxlength attribute and the server
side will respond with a nicer error message if the value is too long.
If our reply tree somehow ends up with cycles or other odd
structures, we only want to consider a reply once, at the first
level in the tree that it appears.
* DEV: Add data-notification-level attribute to category UI
* Show muted categories on the category page by default
This reverts commit ed9c21e42c.
* Remove redundant spec - muted categories are now visible by default
It seems in some situations replies have been moved to other topics but
the `PostReply` table has not been updated. I will try and fix this in a
follow up PR, but for now this fix ensures that every time we ask a post
for its replies that we restrict it to the same topic.
For example /t/ URLs were being replaced if they contained secure-media-uploads so if you made a topic called "Secure Media Uploads Are Cool" the View Topic link in the user notifications would be stripped out.
Refactored code so this secure URL detection happens in one place.
Basically, say you had already downloaded a certain image from a certain URL
using pull_hotlinked_images and the onebox. The upload would be stored
by its sha as an upload record. Whenever you linked to the same URL again
in a post (e.g. in our case an og:image on review.discourse) we would
would reuse the original upload record because of the sha1.
However when you turned on secure media this could cause problems as
the first post that uses that upload after secure media is enabled
will set the access control post for the upload to the new post.
Then if the post is deleted every single onebox/link to that same image
URL will fail forever with 403 as the secure-media-uploads URL fails
if the access control post has been deleted.
To fix this when cooking posts and pulling hotlinked images, we only
allow using an original upload by URL if its access control post
matches the current post, and if the original_sha1 is filled in,
meaning it was uploaded AFTER secure media was enabled. otherwise
we just redownload the media again to be safe, as the URL will always
be new then.
When pull_hotlinked_images tried to run on posts with secure media (which had already been downloaded from external sources) we were getting a 404 when trying to download the image because the secure endpoint doesn't allow anon downloads.
Also, we were getting into an infinite loop of pull_hotlinked_images because the job didn't consider the secure media URLs as "downloaded" already so it kept trying to download them over and over.
In this PR I have also refactored secure-media-upload URL checks and mutations into single source of truth in Upload, adding a SECURE_MEDIA_ROUTE constant to check URLs against too.
Add TopicUploadSecurityManager to handle post moves. When a post moves around or a topic changes between categories and public/private message status the uploads connected to posts in the topic need to have their secure status updated, depending on the security context the topic now lives in.
ReviewableScore#types extend the PostActionTypes with their own, storing the result inside a class variable. To avoid overwriting an existing flag, we need to calculate the next flag ID using these types instead of the PostAction ones. Since we first call the score types to calculate the id, this list gets memoized, leaving us with an outdated list.
To fix this, we now reload ReviewableScore#types after replacing flags.
### 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.
FIX: raised a proper NotFound exception when filtering groups by username with invalid username.
FIX: properly filter the groups based on current user visibility when viewing another user's groups.
DEV: Guardian.can_see_group?(group) is now using Guardian.can_see_groups(groups) instead of duplicating the same code.
FIX: spec for groups_controller#index when group directory is disabled for logged in user.
FIX: groups_controller.sortable specs to actually test all sorting combinations.
DEV: s/response_body/body/g for slightly shorter spec code.
FIX: rewrote the "view another user's groups" specs to test all group_visibility and members_group_visibility combinations.
DEV: Various refactoring for cleaner and more consistent code.
The previous concurrency-safe implementation relied on catching an
index conflict and following through appropriately. Unfortunately
those conflicts were logged to Postgres and there is no easy way
to turn them off.
This solution approaches the problem differently. It should still
be safe under concurrency and not log errors.
I was playing with groups locally and saw this line. I suspect this method isn't needed at all because I don't see any reference to it anywhere in the code, and as far as I know ActiveRecord objects don't have an `id!` method so if this method is called dynamically somewhere it's most likely failing.
6e1fe22 introduced the possiblity for category_users to have a NULL notification_level, so that we can store `last_seen_at` dates without locking the notification level. At the time, this did not affect the topic-tracking-state query. However, the query changes in f434de2 introduced a slight change in behavior.
Previously, a subquery would look for a category_user with notification_level=mute. f434de2 refactored this to remove the subquery, and inverted some of the logic to suit.
The new query checked for `notification_level <> :muted`. If `notification_level` is NULL, this comparison will return NULL. In this scenario, notification_level=NULL means that we should fall back to the default tracking level (regular), and so we want the expression to resolve as true, not false. There was already a check for the existence of the category_users row, but it did not check for the existence of a NOT NULL notification_level.
This commit amends the expression so that the notification_level will only be compared if it is non-null.
Under rare conditions due to bad HTTP timing and so on a draft could be
set at the exact same time from 2 unicorn workers.
When this happened and all the stars aligned, one of the sets would win
and the other would raise an error.
This transparently handles the situation without adding any cost to the
draft system.
The alternative is to add a distributed mutex, tricky DB transaction or handle
the error in the controller. However this seems like a reasonable way to
work around a pretty big edge case.
Previously, categories without any topics were being excluded from the UPDATE query. This means the counter gets stuck, and the category cannot be deleted. This change ensures that the counters get correctly set to zero.
The bug mentioned here
https://meta.discourse.org/t/badge-not-triggering/135896/8
Basically, descriptions for 3 badges: "Out of Love", "Higher Love" and
"Crazy in Love" are granted based on on "max_likes_per_day" and the
description should reflect that.
Restore tl3 reachability by calculating penalty counts vs unsuspend/unsilence.
Only count unsuspend or unsilences that have been made by a user other than
the Discourse system user.
- Using h4 instead of h3 for sub-categories.
- Show category description if it does not have subcategories.
- Implemented equivalent for mobile-view.
- Include description_excerpt in basic serializer. This is needed for
displaying second-level categories in category list.
Follow-up to 9253cb79e3.
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
API keys are now only visible when first created. After that, only the first four characters are stored in the database for identification, along with an sha256 hash of the full key. This makes key usage easier to audit, and ensures attackers would not have access to the live site in the event of a database leak.
This makes the merge lower risk, because we have some time to revert if needed. Once the change is confirmed to be working, we will add a second commit to drop the `key` column.
The following methods have long been deprecated in ruby due to flaws in their implementation per http://blade.nagaokaut.ac.jp/cgi-bin/vframe.rb/ruby/ruby-core/29293?29179-31097:
URI.escape
URI.unescape
URI.encode
URI.unencode
escape/encode are just aliases for one another. This PR uses the Addressable gem to replace these methods with its own encode, unencode, and encode_component methods where appropriate.
I have put all references to Addressable::URI here into the UrlHelper to keep them corralled in one place to make changes to this implementation easier.
Addressable is now also an explicit gem dependency.
