These fields are required when using the UI and if `suspend_until`
params isn't used the user never is actually suspended so we should
require these fields when suspending a user.
This commit is addressing an issue where it is possible that there could
be multiple topic timer jobs running to close a topic or a weird race
condition state causing a topic that was just closed to be re-opened.
By removing the logic from the Topic Timer model into the Topic Timer
controller endpoint we isolate the code that is used for setting an
auto-open or an auto-close timer to just that functionality making the
topic timer background jobs safer if multiple are running.
Possibly in the future if we would like this logic back in the model a
refactor will be needed where we actually pass in the auto-close and
auto-open action instead of mixing it with the close and open
action that is currently being passed to the controller.
When someone wants to add > 1000 users at once they will hit a timeout.
Therefore, we should introduce limit and inform the user when limit is exceeded.
* FIX: Unlike own posts on ownership transfer
If a user has liked a post that has passed the
`post_undo_action_window_mins` system setting window and you transfer ownership
of that post to that user you will be the owner of a post that you have
liked, but cannot unlike resulting in a weird UI behavior. This commit
fixes this issue.
The existing tests didn't check for the timeout window for unliking
posts so I added that in.
I couldn't find a good way to do this logic inside of the guardian class
so rather than duplicating behavior of the `PostActionDestroyer` class
inside of the `PostOwnerChanger` I decided to pass in a "bypass"
variable that could be used to check if the calling class is the
'post_owner_changer' and bypass the guardian instead. I went this route
because the guardian `can_delete_post_action` method has no way of
distinguishing how to allow a user to be able to unlike their own posts
after the timeout window but only on a post owner change.
* use an options hash instead
Enabling the moderators_manage_categories_and_groups site setting will allow moderator users to create/manage groups.
* show New Group form to moderators
* Allow moderators to update groups and read logs, where appropriate
* Rename site setting from create -> manage
* improved tests
* Migration should rename old log entries
* Log group changes, even if those changes mean you can no longer see the group
* Slight reshuffle
* RouteTo /g if they no longer have permissions to view group
The category model already has a default value for `color` and
`text_color` so they don't need to be required via the API. The ember UI
already requires that colors be selected.
The name of the category also doesn't need to be required when updating
the category either because we are already passing in the id for the
category we want to change.
These changes improve the api experience because you no longer have to
lookup the category name, color, or text color before updating a single
category attribute. When creating a category the name is still required.

The `/directory_items` route needs to have a .json url, but the rails
url helper `_path` doesn't return the format of the route.
I tried passing in a format options to `directory_items_path`. Which
works in the rails console
```
[8] pry(main)> directory_items_path(params.merge(:format => :json))
=> "/directory_items.json?page=1"
```
but when I added that some logic to the controller it comes out as
```
/directory_items?format=json&page=1
```
(which is actually how I expect it to work based on how you pass in the
format param). Anyways, because I couldn't figure out how to pass a
format to the `_path` helper I just used URI.parse to append `.json`
manually.
The UI prevents users from trying to create tags on topics when they
don't have permission, but if you are trying to add tags to a topic via
the API and you don't have permission before this change it would
silently succeed in creating the topic, but it wouldn't have any tags.
Now a 422 error will be returned with an error message when trying to
create a topic with tags when tagging is disabled or you don't have
enough trust level to add tags to a topic.
Bug report: https://meta.discourse.org/t/-/70525/14
When a tab is open but left unattended for a while, the red, green, and blue
pills tend to go out of sync.
So whevener we open the notifications menu, we sync up the notification count
(eg. blue and green pills) with the server.
However, the reviewable count (eg. the red pill) is not a notification and
is located in the hamburger menu. This commit adds a new route on the server
side to retrieve the reviewable count for the current user and a ping
(refreshReviewableCount) from the client side to sync the reviewable count
whenever they open the hamburger menu.
REFACTOR: I also refactored the hamburger-menu widget code to prevent repetitive uses
of "this.".
PERF: I improved the performance of the 'notify_reviewable' job by doing only 1 query
to the database to retrieve all the pending reviewables and then tallying based on the
various rights.
* FEATURE: set notification levels when added to a group
This feature allows admins and group owners to define default
category and tag tracking levels that will be applied to user
preferences automatically at the time when users are added to the
group. Users are free to change those preferences afterwards.
When removed from a group, the user's notification preferences aren't
changed.
This commit should cause no functional change
- Split into functions to avoid deep nesting
- Register custom field type, and remove manual json parse/serialize
- Recover from deleted upload records
Also adds a test to ensure pull_hotlinked_images redownloads secure images only once
Apparently latest.json and latest.rss are not routed to the same
controller methods. This change allows for any passed in query
parameters to actually be applied to the rss route.
This came in as a request on meta:
https://meta.discourse.org/t/-/155812/6
Currently, we only reset `email_digests`, `email_level` and `email_messages_level` when the user wants to unsubscribe from all email.
`mailing_list_mode` should be reset as well
There was a bug that even when `email_digest` was set to false but
`digest_after_minutes` was positive, we were not displaying correct
status.
In addition, the message is improved when the user is unsubscribed +
unsubscribe from all is hidden.
Before this commit if you were bulk removing group members and passed in
a user who wasn't currently a member of that group the whole request
would fail. This change will return a 200 response now listing the users
that were removed and those that were skipped.

Category and tag hashtags used to be handled differently even though
most of the code was very similar. This design was the root cause of
multiple issues related to hashtags.
This commit reduces the number of requests (just one and debounced
better), removes the use of CSS classes which marked resolved hashtags,
simplifies a lot of the code as there is a single source of truth and
previous race condition fixes are now useless.
It also includes a very minor security fix which let unauthorized users
to guess hidden tags.
* FIX: Improve category hashtag lookup
This commit improves support for sub-sub-categories and does not include
the ID of the category in the slug, which fixes the composer preview.
* FIX: Sub-sub-categories can be mentioned using only two levels
* FIX: Remove support for three-level hashtags
* DEV: Simplify code
The previous fix (f43c0a5d85) wasn't working for images that were already uploaded.

an upload from its URL.

* FEATURE: Don't display muted/ignored users under "who liked"
Previously, if you clicked on the heart icon below a post
it would show you the avatar for a user even if you ignored or muted
them.
This commit will instead display a (?) icon. The count of likes will
remain correct, but you needn't be reminded of the person you
preferred not to see.
* Use a circle instead of (?) for unknown user
Adds new hidden site settings for rate limits:

Adds an anon cache for searching, caches results of searches for 1 minute
Discourse needs a bunch of data preloaded before it can start up.
Normally we throw blobs of this into the HTML document that is requested
but in some cases that's awkward to retrieve.
For example with Ember CLI you have a separate javascript application
that needs to make its own HTML.
This API endpoint returns a JSON object with all the data Discourse needs to
bootstrap and start up.
In some restricted setups all JS payloads need tight control.
This setting bans admins from making changes to JS on the site and
requires all themes be whitelisted to be used.
There are edge cases we still need to work through in this mode
hence this is still not supported in production and experimental.
Use an example like this to enable:
`DISCOURSE_WHITELISTED_THEME_REPOS="https://repo.com/repo.git,https://repo.com/repo2.git"`
By default this feature is not enabled and no changes are made.
One exception is that default theme id was missing a security check
this was added for correctness.

* test: a spec making sure X-Robots-Tag header is present when needed
/groups path responds to anonymous requests and doesn't skip `check_xhr` method, so we can use it here.
This reverts commit 20780a1eee.
* SECURITY: re-adds accidentally reverted commit:
03d26cd6: ensure embed_url contains valid http(s) uri
* when the merge commit e62a85cf was reverted, git chose the 2660c2e2 parent to land on
instead of the 03d26cd6 parent (which contains security fixes)
* FIX: randomize file name when created from fixtures
When a temporary file is created from fixtures it should have a unique name.
It is to prevent a collision in parallel specs evaluation
* FIX: use /tmp/pid folder to keep fixture files
Signed S3 URLs are valid for 15 seconds, so we can safely allow the browser to cache them for 10 seconds. This should help with large numbers of requests when composing a post with many images.
* DEV: Add framework for filtered plugin registers
Plugins often need to add values to a list, and we need to filter those lists at runtime to ignore values from disabled plugins. This commit provides a re-usable way to do that, which should make it easier to add new registers in future, and also reduce repeated code.
Follow-up commits will migrate existing registers to use this new system
* DEV: Migrate user and group custom field APIs to plugin registry
This gives us a consistent system for checking plugin enabled state, so we are repeating less logic. API changes are backwards compatible
* DEV: Standardize table sorting verbiage
This commit creates a common component that tables can use to make their
headers sortable. This commit also standardizes on using `desc` as the
default and passing in the `asc=true` flag to adjust the sorting
direction.
* Add deprecation warnings
Adds deprecation warnings if using previous params and maintains
backwards compatibility. Set the default sort value for group members to
be asc.
* switch group requests to use common table-header-toggle
* update fixture
This commit prevents a 500 error from occurring if someone is trying to
setup their discourse instance as a sso provider and they don't pass in
a `return_sso_url` in their payload.
* FEATURE: Support for App Shortcuts Menu
This adds a list of shortcuts to a installed Discourse instance.
It can be accessed by right clicks or long press on the app icon.
See https://github.com/MicrosoftEdge/MSEdgeExplainers/blob/master/Shortcuts/explainer.md
List of possible follow ups include:
- Making it admin customizable
- Making it user customizable
- Using SVG icons from the site icon sprite
- Picking an accent color for icons
* FIX: Add type to shortcut menu icons
This refactors default_current_user_provider in a few ways:
- Introduce a generic `api_parameter_allowed?` method which checks for whitelisted routes/formats
- Only read the api_key parameter on allowed routes. It is now completely ignored on other routes (previously it would raise a 403)
- Start reading user_api_key parameter on allowed routes
- Refactor tests as end-end integration tests
A plugin API for PARAMETER_API_PATTERNS will be added soon
Previously we only changed sequence on ownership change, this
cause a race condition between tabs where user could type for a
long time without being warned of an out of date draft.
This change is a radical change and we should watch closely.
Code was already in place to track sequence on the client so no
changes are needed there.
For pages that do not specify canonical URL we will default to `https://SITENAME/PATH`.
This ensures that if a URL is crawled on the CDN the search ranking will transfer to the main site.
Additionally we whitelist the `?page` param
* DEV: api documentation updates
- Created a script to convert json responses to rswag
- Documented several api endpoints
- Switched rswag to use header based auth
* Update script, fix some schema missmatches
Google insists on indexing pages so it can figure out if they
can be removed from the index.
see: https://support.google.com/webmasters/answer/6332384?hl=en
This change ensures the we have special behavior for Googlebot
where we allow indexing, but block the actual indexing via
X-Robots-Tag
Expand SiteSetting.allow_index_in_robots_txt so it also adds a
noindex header if set to false.
This makes sure that nothing is indexed even if it somehow reaches
Google.

If for some reason an update did not go through (for example,
concurrently updating the same topic twice), we were logging something
like:
```
create_errors_json called with unrecognized type: #<Topic
```
This happened because we knew an error occurred but the active record
object had no errors attached.
This patch fixes the issue by attaching a proper error message in the
event that this happens.
The main thrust of this PR is to take all the conditional checks based on the `enable_bookmarks_with_reminders` away and only keep the code from the `true` path, making bookmarks with reminders the core bookmarks feature. There is also a migration to create `Bookmark` records out of `PostAction` bookmarks for a site.
### Summary
* Remove logic based on whether enable_bookmarks_with_reminders is true. This site setting is now obsolete, the old bookmark functionality is being removed. Retain the setting and set the value to `true` in a migration.
* Use the code from the rake task to create a database migration that creates bookmarks from post actions.
* Change the bookmark report to read from the new table.
* Get rid of old endpoints for bookmarks
* Link to the new bookmarks list from the user summary page
* DEV: Use `render_json_error` (Adds specs for Admin::GroupsController)
* DEV: Use a specific error on blank category slug (Fixes a `render_json_error` warning)
* DEV: Use a specific error on reviewable claim conflict (Fixes a `render_json_error` warning)
* DEV: Use specific errors in Admin::UsersController (Fixes `render_json_error` warnings)
* FIX: PublishedPages error responses
* FIX: TopicsController error responses (There was an issue of two separate `Topic` instances for the same record. This makes sure there's only one up-to-date instance.)
- Eliminate superfluous "author wrote" block
- Eliminate block-quote for all posts
- Move participant count and reply count to 1 line
- Prioritize name over username if forum requests
- Use fabrication in list controller spec to speed up spec
There is now an explicit "Delete Bookmark" button in the edit modal. A confirmation is shown before deleting.
Along with this, when the bookmarked post icon is clicked the modal is now shown instead of just deleting the bookmark. Also, the "Delete Bookmark" button from the user bookmark list now confirms the action.
Add a `d d` shortcut in the modal to delete the bookmark.
Sometimes spec which is testing order groups by user count is failing.
My theory is that cause is the randomness of Postgres when the order value is the same for 2 rows.
In spec, we got three groups
`moderator_group` - 0 users
`group` - 1 user
`other_group` - 1 user
And we are expecting that controller will return them in ascending order [moderator, group, other_group]
Because `group` and `other_group` contain the same amount of users, we are dealing with luck
Therefore, I believe that adding one more user to other_group should make that query reliable.
It was not crashing on my local machine, so I am not 100% sure.
This commit is for a frequently requested task on meta so that only 1
API call is needed instead of 3!
In order to create a user via the api and not have them receive an
activation email you can pass in the `active=true` flag. This prevents
sending an email, but it is only half of the solution and puts the db in
a weird state where it has an active user with an unconfirmed email.
This commit fixes that and ensures that if the `active=true` flag is set
the user's email is also marked as confirmed.
This change only applies to admins using the API.

* DEPRECATION: Remove support for api creds in query params
This commit removes support for api credentials in query params except
for a few whitelisted routes like rss/json feeds and the handle_mail
route.
Several tests were written to valid these changes, but the bulk of the
spec changes are just switching them over to use header based auth so
that they will pass without changing what they were actually testing.

* FEATURE: add setting `auto_approve_email_domains` to auto approve users
This commit adds a new site setting `auto_approve_email_domains` to
auto approve users based on their email address domain.
Note that if a domain already exists in `email_domains_whitelist` then
`auto_approve_email_domains` needs to be duplicated there as well,
since users won’t be able to register with email address that is
not allowed in `email_domains_whitelist`.

If the “secure media” site setting is enabled then ALL files uploaded to Discourse (images, video, audio, pdf, txt, zip etc. etc.) will follow the secure media rules. The “prevent anons from downloading files” setting will no longer have any bearing on upload security. Basically, the feature will more appropriately be called “secure uploads” instead of “secure media”.
This is being done because there are communities out there that would like all attachments and media to be secure based on category rules but still allow anonymous users to download attachments in public places, which is not possible in the current arrangement.
Additionally correctly handle cookie path for authentication_data
There were two bugs that exposed an interesting case where two discourse
instances hosted across two subfolder installs in the same domain
with oauth may clash and cause strange redirection on first login:
Log in to example.com/forum1. authentication_data cookie is set with path /
On the first redirection, the current authentication_data cookie is not unset.
Log in to example.com/forum2. In this case, the authentication_data cookie
is already set from forum1 - the initial page load will incorrectly redirect
the user to the redirect URL from the already-stored cookie, to /forum1.
This removes this issue by:
* Setting the cookie for the correct path, and not having it on root
* Correctly removing the cookie on first login
This fix ensures that when a topic title is edited the new title shows
up in the post webhook instead of the old title.
Rather than passing in the old topic object to the PostRevisor the
PostRevisor initializer will load the updated topic object inside of the
initializer if you don't pass it in. This will allow the post_edited
webhook to have the correct topic values.
Original bug reported at:

On some sites when bootstrapping communities it is helpful to bootstrap
with a "light weight" invite code.
Use the site setting `invite_code` to set a global invite code.
In this case the administrator can share the code with
a community which is very easy to remember and then anyone who has
that code can easily register accounts.
People without the invite code are not allowed account registration.
Global invite codes are less secure than indevidual codes, in that they
tend to leak in the community however in some cases when starting a brand
new community the security guarantees of invites are not needed.
A custom date and time can now be selected for a bookmark reminder
The reminder will not happen at the exact time but rather at the next 5 minute interval of the bookmark reminder schedule.
This PR also fixes issues with bulk deleting topic bookmarks.
* This PR implements the scheduling and notification system for bookmark reminders. Every 5 minutes a schedule runs to check any reminders that need to be sent before now, limited to **300** reminders at a time. Any leftover reminders will be sent in the next run. This is to avoid having to deal with fickle sidekiq and reminders in the far-flung future, which would necessitate having a background job anyway to clean up any missing `enqueue_at` reminders.
* If a reminder is sent its `reminder_at` time is cleared and the `reminder_last_sent_at` time is filled in. Notifications are only user-level notifications for now.
* All JavaScript and frontend code related to displaying the bookmark reminder notification is contained here. The reminder functionality is now re-enabled in the bookmark modal as well.
* This PR also implements the "Remind me next time I am at my desktop" bookmark reminder functionality. When the user is on a mobile device they are able to select this option. When they choose this option we set a key in Redis saying they have a pending at desktop reminder. The next time they change devices we check if the new device is desktop, and if it is we send reminders using a DistributedMutex. There is also a job to ensure consistency of these reminders in Redis (in case Redis drops the ball) and the at desktop reminders expire after 20 days.
* Also in this PR is a fix to delete all Bookmarks for a user via `UserDestroyer`
This commit ensures that an error is thrown when a user fails to be
removed from a group instead of silently failing.
This means when using the api you will receive a 400 instead of a 200 if
there is a failure. The remove group endpoint allows the removal of
multiple users, this change means that if you try to delete 10 users,
but 1 of them fails you will receive a 400 instead of 200 even though
the other 9 were removed successfully. Rather than adding a bunch more
complexity I think this is more than adequate for most use cases.
Introduces `/user-cards.json`
Also allows the client-side user model to be passed an existing promise when loading, so that multiple models can share the same AJAX request

Anonymous users could query the invite json and see counts and
summaries which is not allowed in the UX of Discourse.
This commit has those endpoints return a 403 unless the user is
allowed to invite.
When secure media is enabled and an attachment is marked as secure we want to use the full url instead of the short-url so we get the same access control post protections as secure media uploads.
When admin changes a user's email from the preferences page of that user:
* The user will not be sent an email to confirm that their
email is changing. They will be sent a reset password email
so they can set the password for their account at the new
email address.
* The user will still be sent an email to their old email to inform
them that it was changed.
* Admin and staff users still need to follow the same old + new
confirm process, as do users changing their own email.
Now if a group is visible but unmentionable, users can search for it
when composing by typing with `@`, but it will be rendered without the
grey background color.
It will also no longer pop up a JIT warning saying "You are about to
mention X people" because the group will not be mentioned.
### UI Changes
If `SiteSetting.enable_bookmarks_with_reminders` is enabled:
* Clicking "Bookmark" on a topic will create a new Bookmark record instead of a post + user action
* Clicking "Clear Bookmarks" on a topic will delete all the new Bookmark records on a topic
* The topic bookmark buttons control the post bookmark flags correctly and vice-versa
Disabled selecting the "reminder type" for bookmarks in the UI because the backend functionality is not done yet (of sending users notifications etc.)
### Other Changes
* Added delete bookmark route (but no UI yet)
* Added a rake task to sync the old PostAction bookmarks to the new Bookmark table, which can be run as many times as we want for a site (it will not create duplicates).
When a tag is restricted to a secured category that the user can't see,
the message was saying that it wasn't restricted to any categories.
Now it will say it's restricted to categories you can't access.
This commit adds support for an optional "logout" parameter in the
payload of the /session/sso_provider endpoint. If an SSO Consumer
adds a "logout=true" parameter to the encoded/signed "sso" payload,
then Discourse will treat the request as a logout request instead
of an authentication request. The logout flow works something like
this:
* User requests logout at SSO-Consumer site (e.g., clicks "Log me out!"
on web browser).
* SSO-Consumer site does whatever it does to destroy User's session on
the SSO-Consumer site.
* SSO-Consumer then redirects browser to the Discourse sso_provider
endpoint, with a signed request bearing "logout=true" in addition
to the usual nonce and the "return_sso_url".
* Discourse destroys User's discourse session and redirects browser back
to the "return_sso_url".
* SSO-Consumer site does whatever it does --- notably, it cannot request
SSO credentials from Discourse without the User being prompted to login
again.
When 'categories topics' setting is set to 0, the system will
automatically try to find a value to keep the two columns (categories
and topics) symmetrical.
The value is computed as 1.5x the number of top level categories and at
least 5 topics will always be returned.
Adds a new route `/u/{username}/card.json`, which has a reduced number of fields. This change is behind a hidden site setting, so we can test compatibility before rolling out.
