This fix ensures that searches that contain a null byte return a 400
error instead of causing a 500 error.
For some reason from rspec we will reach the raise statement inside
of the `rescue_from ArgumentError` block, but outside of rspec it will
not execute the raise statement and so a 500 is thrown instead of
reaching the `rescue_from Discourse::InvalidParameters` block inside of
the application controller.
This fix raises Discourse::InvalidParameters directly from the search
controller instead of relying on `PG::Connection.escape_string` to
raise the `ArgumentError`.
The payload when receiving a notification webhook is pointless without
knowing which user the notification is for. This fix adds the user_id to
the notification serializer so that when you receive a notification
webhook you can properly identify which user the notification is for.
See
https://meta.discourse.org/t/getting-the-target-user-for-notification-webhook-events/129052?u=blake
for more details.
While editing the first post it does't bumped the topic when the new post revision created. Because we wrongly assumed that the hidden tags are changed even when no tags are updated.
Doing .pluck(:column).first is a very common pattern in Discourse and in
most cases, a limit cause isn't being added. Instead of adding a limit
clause to all these callsites, this commit adds two new methods to
ActiveRecord::Relation:
pluck_first, equivalent to limit(1).pluck(*columns).first
and pluck_first! which, like other finder methods, raises an exception
when no record is found
Trying to truncate encoded slugs will mean that we have to keep the URL
valid, which can be tricky as you have to be aware of multibyte
characters.
Since we already have upper bounds for the title, the slug won't grow
for more than title*6 in the worst case. The slug column in the topic
table can store that just fine.
Added a test to ensure that a generated slug is a valid URL too, so we
don't introduce regressions in the future.
Under exceptional situations the automatic draft feature can fail.
This new **hidden, default off** site setting
`backup_drafts_to_pm_length` will automatically backup any draft that is
saved by the system to a dedicated PM (originating from self)
The body of that PM will contain the text of the reply.
We can enable this feature strategically on sites exhibiting issues to
diagnose issues with the draft system and offer a recourse to users who
appear to lose drafts. We automatically checkpoint these drafts every 5
minutes forcing a new revision each 5 minutes so you can revert to old
content.
Longer term we are considering automatically enabling this kind of feature
for extremely long drafts where the risk is really high one could lose
days of writing.
This feature amends it so instead of using one challenge and honeypot
statically per site we have a rotating honeypot and challenge value which
changes every hour.
This means you must grab a fresh copy of honeypot and challenge value once
an hour or account registration will be rejected.
We also now cycle the value of the challenge when after successful account
registration forcing an extra call to hp.json between account registrations
Client has been made aware of these changes.
Additionally this contains a JavaScript workaround for:
https://bugs.chromium.org/p/chromium/issues/detail?id=987293
This is client side code that is specific to Chrome user agent and swaps
a PASSWORD type honeypot with a TEXT type honeypot.
After a small conversation, we decided that we can set `public_file_server.enabled` to false in the `test` environment to have the same value as `production`.
When a category has a subcategory, we ensure that no one who can see the
subcategory cannot see the parent. However, we don't take into account
the fact that, when no CategoryGroups exist, the default is that
everyone has full permissions.
Moving posts also moves the read state (`topic_users` table) to the destination topic. This changes that behavior so that only users who posted in the destination topic will have the original notification level (probably "watching") of the original topic. The notification level for all other users will be set to "regular".
Previously the 'local_cdn_url' method didn't returned the correct cdn url. So we written few incorrect spec tests too.\n\nf92a6f7ac5228342177bf089d269e2f69a69e2f5
When an admin changes the site setting slug_generation_method to
encoded, we weren't really encoding the slug, but just allowing non-ascii
characters in the slug (unicode).
That brings problems when a user posts a link to topic without the slug, as
our topic controller tries to redirect the user to the correct URL that contains
the slug with unicode characters. Having unicode in the Location header in a
response is a RFC violation and some browsers end up in a redirection loop.
Bug report: https://meta.discourse.org/t/-/125371?u=falco
This commit also checks if a site uses encoded slugs and clear all saved slugs
in the db so they can be regenerated using an onceoff job.
Post timings are created by `topic_id` and `post_number` and it's possible that the destination topic already contains post timings for non-existent posts. For example, this can happen if the destination topic was previously split and Discourse recorded post timings for moved posts in the destination topic.
This commit ensures that all timings which reference non-existent posts are deleted from the destination topic before the posts are moved.
If the setting is turned on, then the user will receive information
about the subject: if it was deleted or requires some special access to
a group (only if the group is public). Otherwise, the user will receive
a generic #404 error message. For now, this change affects only the
topics and categories controller.
This commit also tries to refactor some of the code related to error
handling. To make error pages more consistent (design-wise), the actual
error page will be rendered server-side.
Using popups is becoming increasingly rare. Full page redirects are already used on mobile, and for some providers. This commit removes all logic related to popup authentication, leaving only the full page redirect method.
For more info, see https://meta.discourse.org/t/do-we-need-popups-for-login/127988
It was possible to add a category to more than one default group, e.g. "default categories muted" and "default categories watching first post".
The bug was caused by category validations inadvertently comparing strings and numbers.
* FEATURE: Adds an extra protection layer when decompressing files.
* Rename exporter/importer to zip importer. Update old locale
* Added a new composite class to decompress a file with multiple strategies
* Set max file size inside a site setting
* Ensure that file is deleted after compression
* Sanitize path and files before compressing/decompressing
Zeitwerk simplifies working with dependencies in dev and makes it easier reloading class chains.
We no longer need to use Rails "require_dependency" anywhere and instead can just use standard
Ruby patterns to require files.
This is a far reaching change and we expect some followups here.
Adds 2 factor authentication method via second factor security keys over [web authn](https://developer.mozilla.org/en-US/docs/Web/API/Web_Authentication_API).
Allows a user to authenticate a second factor on login, login-via-email, admin-login, and change password routes. Adds registration area within existing user second factor preferences to register multiple security keys. Supports both external (yubikey) and built-in (macOS/android fingerprint readers).
Currently, the topic is only validated for censored words and should be validated for blocked words as well.
Blocked word validation is now used by both Post and Topic. To avoid code duplication, I extracted blocked words validation code into separate Validator, and use it in both places.
The only downside is that even if the topic contains blocked words validation message is saying "Your post contains a word that's not allowed: tomato" but I think this is descriptive enough.
Previously, calculating thresholds for reviewables was done based on the
50th and 85th percentile across all reviewables. However, many forum
owners provided feedback that these thresholds were too easy to hit, in
particular when it came to auto hiding content.
The calculation has been adjusted to base the priorities on reviewables
that have a minimum of 2 scores (flags). This should push the amount of
flags required to hide something higher then before.
On forums with very few flags you don't want to calculate averages
because they won't be very useful. Stick with the defaults until we hit
15 reviewables at least.
Forums without previously calculated scores would return the same values
for low/medium/high sensitivity. Now those are scaled based on the
default value.
The default value has also been changed from 10.0 to 12.5 based on
observing data from live discourse forums.
This means that TL0 users can message groups with "Who can message this
group?" set to "Everyone".
It also means that members of a group with "Who can message this
group?" set to "members, moderators and admins" can also message the
group, even when their trust level is below min_trust_to_send_messages.
Prior to the new review queue there were a couple special cases where
posts would be auto hidden:
* If a TL3 or above flagged a TL0 post as spam
* If a TL4 or above flagged a non-staff, non-TL4 post as spam, inappropriate or off
topic.
These cases are now removed in favour of the scoring system.
* Adjustments to pass specs on Rails 6.0.0
* Use classic autoloader instead of Zeitwerk
* Update Rails 6.0.0 deprecated methods
* Rails 6.0.0 not allowing column with integer name
* Drop freedom_patches/rails6.rb
* Default value for trigger_transactional_callbacks? is true
* Bump rspec-rails version to 4.0.0.beta2
New site setting: `embed_any_origin` that will send postMessages to
wildcard origins `*` instead of the referer.
Most of the time you won't want to do this, so the setting is default to
`false`. However, there are certain situations where you want to allow
embedding to send post messages when there is no HTTP REFERER.
For example, if you created a native mobile app and you wanted to embed a list
of Discourse topics as HTML. In the code your HTML would be a
static file/string, which would not be able to send a referer. In this
case, the site setting will allow the embed to work.
From a security standpoint we currently only use `postMessage` to send
data about the size of the HTML document and scroll position, so it
should be enable if required with minimal security ramifications.
* FEATURE: Add tl2 threshold for editing new posts
* Adds a new setting and for tl2 editing posts (30 days same as old value)
* Sets the tl0/tl1 editing period as 1 day
* FIX: Spec uses wrong setting
* Fix site setting on guardian spec
* FIX: post editing period specs
* Avoid shared examples
* Use update_columns to avoid callbacks on user during tests
If you click a (?) icon beside the reviewable status a pop up will
appear with expanded informatio that explains how the reviewable got its
score, and how it compares to system thresholds.
This commit introduces 2 features:
1. DISCOURSE_COMPRESS_ANON_CACHE (true|false, default false): this allows
you to optionally compress the anon cache body entries in Redis, can be
useful for high load sites with Redis that lives on a separate server to
to webs
2. DISCOURSE_ANON_CACHE_STORE_THRESHOLD (default 2), only pop entries into
redis if we observe them more than N times. This avoids situations where
a crawler can walk a big pile of topics and store them all in Redis never
to be used. Our default anon cache time for topics is only 60 seconds. Anon
cache is in place to avoid the "slashdot" effect where a single topic is
hit by 100s of people in one minute.
Start tracking the date an api key was last used. This has already been
the case for user_api_keys.
This information can provide us with the ability to automatically expire
unused api keys after N days.
The URL '/images/transparent.png' will be used in the cooked content if upload record not found. In that case we have to use 'short_url' as image src in 'post.each_upload_url' method.
This allows custom plugins such as prometheus exporter to log how many
requests are stored in the anon cache vs used by the anon cache.
This metric allows us to fine tune cache behaviors
* FIX: User should get notified when a post is deleted
* FEATURE: Notify posters when restoring flagged posts
* Fix typo

* Improve tests
This reverts commit e805d44965.
We now have mechanisms in place to ensure heartbeat will always
be scheduled even if the scheduler is overloaded per: 098f938b
When there is an overridden text in the database that belongs to
a pluralized key which doesn't exist in English anymore, the
Customize Texts admin page was unusable. This stops those keys from
ever being returned by a search.
* The read indicator now shows up when no member has read the last post of the topic (written by a non-member)
* The read indicator works on mobile and receives live updates from message bus
* The icon we display in the topic list was changed
* Added a title to the indicator to indicate its purpose when hovering over it
The client-side theme-selector would always apply the first in a series of file change notifications. This has been fixed, so it now applies the most recent notification.
Duplicate notifications were being sent because
- The remote_theme autosave was causing every change notification to be doubled
- Color scheme change notifications were being sent every time a theme was uploaded, even if the colors were unchanged
These duplicate notifications have been fixed, and a spec added to ensure it does not regress in future
When activating a user via an external provider, this would cause the "this account is not activated" message to show on the first attempt, even though the account had been activated correctly.
- Adds support for iOS Universal Links via an `apple-app-site-association` endpoint
Adds support for Google Digital Asset Links at the `.well-known/assetlinks.json` endpoint
* Revert "Revert "FEATURE: Publish read state on group messages. (#7989) [Undo revert] (#8024)""
This reverts commit 36425eb9f0.
* Fix: Show who read only if the attribute is enabled
* PERF: Precalculate the last post readed by a group member
* Use book-reader icon instear of far-eye
* FIX: update topic groups correctly
* DEV: Tidy up read indicator update on write
This is a very long standing bug we had, if a plugin attempted to amend a
serializer core was not "correcting" the situation for all descendant classes
this often only showed up in production cause production eager loads serializers
prior to plugins amending them.
This is a critical fix for various plugins
* FIX: Heartbeat check per sidekiq process
* Rename method
* Remove heartbeat queues of previous bootups
* Regis feedback
* Refactor before_start
* Update lib/demon/sidekiq.rb

* Expire redis keys after 3600 seconds
* Don't use redis to store the list of queues
Previously, a regular user could not edit the title or category
of a topic if a hidden tag had already been applied.
This also stops hidden tag names from leaking in the error message.
This change allows themes and components access to theme assets.
This means that inside theme js you can now get the URL for an asset with:
```
settings.theme_uploads.name
```
* Reenable: "FEATURE: Publish read state on group messages. (#7989)"
This reverts commit 67f5cc1ce8.
* FIX: Read indicator only appears when the group setting is enabled
* Enable or disable read state based on group attribute
* When read state needs to be published, the minimum unread count is calculated in the topic query. This way, we can know if someone reads the last post
* The option can be enabled/disabled from the UI
* The read indicator will live-updated using message bus
* Show read indicator on every post
* The read indicator now shows read count and can be expanded to see user avatars
* Read count gets updated everytime someone reads a message
* Simplify topic-list read indicator logic
* Unsubscribe from message bus on willDestroyElement, removed unnecesarry values from post-menu, and added a comment to explain where does minimum_unread_count comes from
Previously we relied on side effects to set tracking state correctly
when inviting groups to messages
Also has a minor optimisation in that we use pluck instead of pulling in
full record
Previously we would unconditionally issue an "invited_to_pm" notification
to all non muting users.
New behavior
- Watching and Watching first post get notified
- Tracking get a new "summary" message
- The rest get nothing
This is consistent with topic creation and way clearer
If enabled, this will fire a webhook whenever a user's notification has
been created. This could potentially be a lot of data depending on your
forum, and should be used carefully since it includes everything all users
will see in their feeds.
This adds support for a `<d-topics-list>` tag you can embed in your site
that will be rendered as a list of discourse topics. Any attributes on
the tag will be passed as filters. For example:
`<d-topics-list discourse-url="URL" category="1234">` will filter to category 1234.
To use this feature, enable the `embed topics list` site setting. Then
on the site you want to embed, include the following javascript:
`<script
src="http://URL/javascripts/embed-topics.js"></script>`
Where `URL` is your discourse forum's URL.
Then include the `<d-topics-list discourse-url="URL">` tag in your HTML document and it will
be replaced with the list of topics.
There are 5 visibility levels (similar to group visibility)
public (default)
logged-in users
members only
staff
owners
Admins & group owners always have visibility to group members.
When a user liked, unliked and liked again the same post, the poster
would receive a notification such as "X and X liked ...". This happened
because PostActionNotifier.post_action_created was called twice.
Theme developers can now add any of the transformed color variables to their color scheme in about.json. For example
```
"color_schemes": {
"Light": {
"primary": "333333",
"secondary": "ffffff",
"primary-low": "ff0000"
}
},
```
would override the primary-low variable when compiling SCSS for the color scheme. The primary-low variable will also be visible in administrator color palette UI.
This displays more useful messages for the most common issues we see:
- CSRF (when the user switches browser)
- Invalid IAT (when the server clock is wrong)
- OAuth::Unauthorized for OAuth1 providers, when the credentials are incorrect
This commit also stops earlier for disabled authenticators. Now we stop at the request phase, rather than the callback phase.
All posts created by the user are counted unless they are deleted,
belong to a PM sent between a non-human user and the user or belong
to a PM created by the user which doesn't have any other recipients.
It also makes the guardian prevent self-deletes when SSO is enabled.
Temporarily recreate already dropped functions in the discourse_functions schema in order to allow restoring of backups which still reference dropped functions.
The message_bus performs a fair amount of work prior to hijacking requests
this change ensures that if there is a situation where the server is flooded
message_bus will inform client to back off for 30 seconds + random(120 secs)
This back-off is ultra cheap and happens very early in the middleware.
It corrects a situation where a flood to message bus could cause the app
to become unresponsive
MessageBus update is here to ensure message_bus gem properly respects
Retry-After header and status 429.
Under normal state this code should never trigger, to disable raise the
value of DISCOURSE_REJECT_MESSAGE_BUS_QUEUE_SECONDS, default is to tell
message bus to go away if we are queueing for 100ms or longer
If a post is flagged after an action was already performed on it, it
will update the previous Reviable instance and not create a new one.
The notification logic was implemented in the :create callback which was
completely skipped in this case.
There are situations where depending on site settings, actions could be
taken due to flags (for example, hiding a post) but those actions were
not visibile in the review queue due to visibility settings.
This patch makes sure that the minimum score required for an action such
as hiding a post needs to meet the visibility for a moderator to see it.
Enable the new setting "post excerpts in emails" to send excerpts
instead of complete posts in notification emails. Control the length of
excerpts with the "post excerpt maxlength" setting.
This feature allows @ mentions to prioritize showing members of a group who
have explicit permission to a category.
This makes it far easier to @ mention group member when composing topics in
categories where only the group has access.
For example:
If Sam, Jane an Joan have access to bugs category.
Then `@` will auto complete to (jane,joan,sam) ordered on last seen at
This feature works on new topics and existing topics. There is an explicit
exclusion of trust level 0,1,2 groups cause they get too big.
- Client-side censoring fixed for non-chrome browsers. (Regular expression rewritten to avoid lookback)
- Regex generation is now done on the server, to reduce repeated logic, and make it easier to extend in plugins
- Censor tests are moved to ruby, to ensure everything works end-to-end
- If "watched words regular expressions" is enabled, warn the admin when the generated regex is invalid
* UX: Rename "Keep Post" to "Keep Post Hidden" when hidden
This is based on this feedback:
https://meta.discourse.org/t/category-group-review-moderation/116478/19
When a post is hidden this makes the operation much more clear.
* REFACTOR: Better support for aliases for actions
Allow calls on alias actions and delegate to the original one.
This is less code but also simplifies tests where the action might
be "agree_and_keep" or "agree_and_keep_hidden" which are the same.
* REFACTOR: Rename SiteSetting.disable_edit_notifications to disable_system_edit_notifications
- The older name could cause some confusion because the setting does not disable all edit notifications, only system ones.
* FIX: Add frozen_string_literal: true in the migration
* DEV: Deprecate 'disable_edit_notifications'
This feature adds the ability to customize the HTML part of all emails using a custom HTML template and optionally some CSS to style it. The CSS will be parsed and converted into inline styles because CSS is poorly supported by email clients. When writing the custom HTML and CSS, be aware of what email clients support. Keep customizations very simple.
Customizations can be added and edited in Admin > Customize > Email Style.
Since the summary email is already heavily styled, there is a setting to disable custom styles for summary emails called "apply custom styles to digest" found in Admin > Settings > Email.
As part of this work, RTL locales are now rendered correctly for all emails.
