The welcome topic user tip was for admins only, but in general, user
tips should be used for guiding new users through the features that
Discourse offers. For this reason, we decided to remove the user tip.
This commit also includes a few more copy tweaks to the welcome topic.
We have been struggling lately finding site settings due to 30 setting limit
This was introduced for performance reasons a while back but is no longer as
needed given that ember is faster.
Additionally searching is hard, so allow people to use fuzzy search against
setting name.
* FIX: Displaying the wrong number of minimum tags in the composer
When the minimum number of tags set for the category is larger than the minimum number of tags
set in the category tag-groups, the composer was displaying the wrong value.
This commit fixes the value displayed in the composer to show the max value between the required
for the category and the tag-groups set for the category.
This bug was reported on Meta in https://meta.discourse.org/t/tags-from-multiple-tag-groups-required-only-suggest-select-at-least-one-tag/263817
* FIX: Limiting tags in categories not working as expected
When a category was restricted to a tag group A, which was set to only allow
one tag from the group per topic, selecting a tag belonging only to A returned
other tags from A that also belonged to other group/s (if any).
Example:
Tag group A: alpha, beta, gamma, epsilon, delta
Tag group B: alpha, beta, gamma
Both tag groups set to only allow one tag from the group per topic.
If Category 1 was set to only allow tags from the tag group A, and the first tag
selected was epsilon, then, because they also belonged to tag group B, the tags
alpha, beta, and gamma were still returned as valid options when they should not be.
This commit ensures that once a tag from a tag group that restricts its tags to
one per topic is selected, no other tag from this group is returned.
This bug was reported on Meta in https://meta.discourse.org/t/limiting-tags-to-categories-not-working-as-expected/263143.
* FIX: Moving topics does not prompt to add required tag for new category
When a topic moved from a category to another, the tag requirements
of the new category were not being checked.
This allowed a topic to be created and moved to a category:
- that limited the tags to a tag group, with the topic containing tags
not allowed.
- that required N tags from a tag group, with the topic not containing
the required tags.
This bug was reported on Meta in https://meta.discourse.org/t/moving-tagged-topics-does-not-prompt-to-add-required-tag-for-new-category/264138.
* FIX: Editing topics with tag groups from parents allows incorrect tagging
When there was a combination between parent tags defined in a tag group
set to allow only one tag from the group per topic, and other tag groups
relying on this restriction to combine the children tag types with the
parent tag, editing a topic could allow the user to insert an invalid
combination of these tags.
Example:
Automakers tag group: landhover, toyota
- group set to limit one tag from the group per topic
Toyota models group: land-cruiser, hilux, corolla
Landhover models group: evoque, defender, discovery
If a topic was initially set up with the tags toyota, land-cruiser it was
possible to edit it by removing the tag toyota and adding the tag landhover
and other landhover model tags like evoque for example.
In this case, the topic would end up with the tags toyota, land-cruiser,
landhover, evoque because Discourse will automatically insert the
missing parent tag toyota when it detects the tag land-cruiser.
This combination of tags would violate the restriction specified in
the Automakers tag group resulting in an invalid combination of tags.
This commit enforces that the "one tag from the group per topic"
restriction is verified before updating the topic tags and also
make sure the verification checks the compatibility of parent tags that
would be automatically inserted.
After the changes, the user will receive an error similar to:
The tags land-cruiser, landhover cannot be used simultaneously.
Please include only one of them.
- Update welcome topic copy
- Edit the welcome topic automatically when the title or description changes
- Remove “Create your Welcome Topic” banner/CTA
- Add "edit welcome topic" user tip
The issues fixed:
1. Previously all static pages (e.g. login-required landing page, /tos, /privacy, forgot-password) were wrapped in the faq-read-tracking component
2. All these pages shared one controller with methods that were relevant to one route
3. There were two route-generating functions: `static-route-builder` and `build-static-route` 🤣
4. They were using the deprecated `renderTemplate()` API
5. A slight misuse of Ember API (`controllerFor()`)
6. Small mark-faq-read related bugs
added site toggle functionality through site settings
added tests to implemented feature
Introduced suggested correction
renamed find_new_topic method and deleted click_new_topic_button method
Currently the /new-category url can be accessed by moderators, regardless of whether the Site Setting for moderators_manage_categories_and_groups is true or false.
On top of this, non authorized users can also access this page but shows errors (no 404 loaded).
Since the 404 redirect happens within Ember, we need to allow the site setting value to be accessed within JS.
After this change all non admin users will see a 404 for this route, the exception being moderators if the moderators_manage_categories_and_groups setting has a value of true.
/t/73360
* DEV: move sidebar community section to database
Before, community section was hard-coded. In the future, we are planning to allow admins to edit it. Therefore, it has to be moved to database to `custom_sections` table.
Few steps and simplifications has to be made:
- custom section was hidden behind `enable_custom_sidebar_sections` feature flag. It has to be deleted so all forums, see community section;
- migration to add `section_type` column to sidebar section to show it is a special type;
- migration to add `segment` column to sidebar links to determine if link should be displayed in primary section or in more section;
- simplify more section to have one level only (secondary section links are merged);
- ensure that links like `everything` are correctly tracking state;
- make user an anonymous links position consistence. For example, from now on `faq` link for user and anonymous is visible in more tab;
- delete old community-section template.
Group user event webhooks filtered by group fail silently
because the `group_ids` job arg wasn't being passed into the job.
This change add's `group_ids` to the `EmitWebHookEvent` jobs queued for
`user_added_to_group` and `user_removed_from_group` events.
Currently, only user badge grants emit webhook events. This change
extends the `user_badge` webhook to emit user badge revocation events.
A new `user_badge_revoked` event has been introduced instead of relying
on the existing `user_badge_removed` event. `user_badge_removed` emitted
just the `badge_id` and `user_id` which aren't helpful for generating a
meaningful webhook payload for revoked(deleted) user badges.
The new event emits the user badge object.
Responding to negative behaviour tends to solicit more of the same. Common wisdom states: "don't feed the trolls".
This change codifies that advice by introducing a new nudge when hitting the reply button on a flagged post. It will be shown if either the current user, or two other users (configurable via a site setting) have flagged the post.
* FEATURE: add a setting to allowlist DiscourseConnect return path domains
This commit adds a site setting to allowlist DiscourseConnect return
path domains. The setting needs supports exact domain or wildcard
character (*) to allow for any domain as return path.
* Add more specs to clarify what is allowed in site setting
* Update setting description to explain what is allowed
This feature will allow sites to define which emoji are not allowed. Emoji in this list should be excluded from the set we show in the core emoji picker used in the composer for posts when emoji are enabled. And they should not be allowed to be chosen to be added to messages or as reactions in chat.
This feature prevents denied emoji from appearing in the following scenarios:
- topic title and page title
- private messages (topic title and body)
- inserting emojis into a chat
- reacting to chat messages
- using the emoji picker (composer, user status etc)
- using search within emoji picker
It also takes into account the various ways that emojis can be accessed, such as:
- emoji autocomplete suggestions
- emoji favourites (auto populates when adding to emoji deny list for example)
- emoji inline translations
- emoji skintones (ie. for certain hand gestures)
This adds a SiteSetting, which when enabled, creates a small_action post for tag/category changes to the topic. It uses `topic.add_moderator_post, and passes raw text in, to describe the change.
Invite only and Discourse connect could not be enabled at the same time
because of some legacy reason. This is a follow up commit to ce04db8,
355d51a and 40f6ceb.
This goal may vary for different types of communities, but 20% is a more reasonable target as a default for the ratio of daily active users / monthly active users (DAU/MAU).
Before, incorrectly filled fields were marked with red border. Now, additional information under the field is displayed to notify the user what is incorrect.
/t/93696
In production, `eager_load=true`. This sometimes leads to boot errors which are not present in dev/test environments. Running `zeitwerk:check` in CI will help us to pick up on any errors early.
This commit also introduces a `DISCOURSE_ZEITWERK_EAGER_LOAD` environment variable to make it easier to toggle the behaviour when developing locally.
This comment has nothing to do with the `eager_load` configuration. It must be left over from some historical refactoring. Removing to avoid confusion.
Currently the auto-bump cooldown is hard-coded to 24 hours.
This change makes the highlighted 24 hours part configurable (defaulting to 24 hours), and the rest of the process remains the same.
This uses the new CategorySetting model associated with Category. We decided to add this because we want to move away from custom fields due to the lack of type casting and validations, but we want to keep the loading of these optional as they are not needed for almost all of the flows.
Category settings will be back-filled to all categories as part of this change, and creating a new category will now also create a category setting.

Way back when this was introduced way back in b96c10a903
I didn't have any frame of reference for what these max rate
limit numbers should be, so 10 seemed like a reasonable limit
until a real world case where this did not make sense came
along.
The time has come.
Moving these into site settings, which are hidden since in most
cases there is no need to change these.
- Remove no-longer-used `commits-widget` and `site_customizations` paths
- Add `/presence/`
- Move from regex to strings. The unanchored regexes were causing unexpected behaviour (e.g. if a topic had the word `assets` in its slug, it would be skipped). When passed strings, mini-profiler uses `String#starts_with?` for comparison
- Add `Discourse.base_path` to ensure proper functionality in subfolder environments
Mini-profiler causes routes to become uncacheable. When using mini_profiler in production, the lack of cache on these routes can have a noticeable impact on performance/rate-limiting.
What is the problem?
We have a hidden site setting `show_category_definitions_in_topic_lists`
which is set to false by default. What this means is that category
definition topics are not shown in the topic list by default. Only the
category definition topic for the category being viewed will be shown.
However, we have a bug where we would show that a category has new
topics when a new child category along with its category definition
topic is created even though the topic list does not list the child
category's category definition topic.
What is the fix here?
This commit fixes the problem by shipping down an additional
`is_category_topic` attribute in `TopicTrackingStateItemSerializer` when
the `show_category_definitions_in_topic_lists` site setting has been set
to false. With the new attribute, we can then exclude counting child
categories' category definition topics when counting new and unread
counts for a category.

Rails introduced a environment variables RAILS_LOG_TO_STDOUT in the

This commit introduces a few experimental changes to the New topics list and "Everything" link in the sidebar:
1. Make the New topics list include unread topics
2. Make the Everything section in the sidebar link to the New topics list (`/new`)
3. Remove "unread" or "new" text next to the count and keep the count
4. The count is a sum of new and unread topics counts
All of these of changes are behind an off-by-default feature flag. I've not written extensive tests for these changes because they're highly experimental.
Internal topic: t/77234.
With the introduction of the sidebar navigation menu, the design team at
Discourse redesigned the user profile navigation to better coexist with
the sidebar.
The current default timeout is hardcoded to 2 seconds which is proving
too low for certain cases, and resulting in sporadic timeouts due to slow DNS queries.

**This PR creates a new core reusable component wraps a character counter around any input.**
The component accepts the arguments: `max` (the maximum character limit), `value` (the value of text to be monitored).
It can be used for example, like so:
```hbs
<CharCounter @max="50" @value={{this.charCounterContent}}>
<textarea
placeholder={{i18n "styleguide.sections.char_counter.placeholder"}}
{{on "input" (action (mut this.charCounterContent) value="target.value")}}
class="styleguide--char-counter"></textarea>
</CharCounter>
```
**This PR also:**
1. Applies this component to the chat plugins edit channel's *Edit Description** modal, thereby replacing the simple text area which provided no visual indication when text exceeded the max allowed characters.
2. Adds an example to the `/styleguide` route

- Reduce duplication of terms in post index from unlimited to 6. This will
result in reduced index size and reduced weighting for posts containing
a huge amount of duplicate terms. (Eg: a post containing "sam sam sam sam
sam sam sam sam", will index as "sam sam sam sam sam sam", only including
the word up to 6 times.) This corrects a flaw where title weighting could
be ignored.
- Prioritize exact matches of words in titles. Our search always performs
a prefix match. However we want to give special weight to exact title matches
meaning that a search for "sum" will find topics such as "the sum of us" vs
"summer in spring".
- Pick up fixes to our search algorithm which are missing from old indexes.
Specifically pick up the fix that indexes URLs properly. (`https://happy.com`
was stemmed to `happi` in keywords and then was not searchable)
see also:
https://meta.discourse.org/t/refinements-to-search-being-tested-on-meta/254158
Indexing will take a while and work in batches, in the background.
Since ad6c028484
in the zeitwork repo which was introduced to discourse/discourse in PR #20253,
the `autoloads` attribute on the loader has been marked `internal`, which means
that it errors if we try to access it directly.
Instead we should access it via the "mangled" version so it is clear
we're accessing an internal property, which is `__autoloads`.
Without this, any time a ruby file is saved the
000-development_reload_warnings.rb initializer will error.
Remove the per user groups based site setting in favor of a global site setting as we want to roll the glimmer topic timeline out to anon users as well as site users.

This commits adds the ability to add a header to the embedded comments
view. One use case for this is to allow `postMessage` communication
between the comments iframe and the parent frame, for example, when
toggling the theme of the parent webpage.
This removes lots of unused strings. Some of them were never used and some of them weren't removed when features changed...
* `js.pause_notifications.remaining` was removed in 836cbfe7ae
* Looks like `deleted` was added in 651cfba93f but was never used
* Looks like `image` was removed in a9e502936f
Allows users to configure their own custom sidebar sections with links withing Discourse instance. Links can be passed as relative path, for example "/tags" or full URL.
Only path is saved in DB, so when Discourse domain is changed, links will be still valid.
Feature is hidden behind SiteSetting.enable_custom_sidebar_sections. This hidden setting determines the group which members have access to this new feature.
Currently, when doing `@mention` for users we have 0 tolerance for typos and misspellings.
With this patch, if a user search doesn't return enough results we go and use `pg_trgm` features to try and find more matches based on trigrams of usernames and names.
It also introduces GiST indexes on those fields in order to improve performance of this search, going from 130ms down to 15ms in my tests.
This is all gated in a feature flag and can be enabled by running `SiteSetting.user_search_similar_results = true` in the rails console.

The new `prioritize_exact_search_match` can be used to force the search
algorithm to prioritize exact term matches in title when ranking results.
This is scoped narrowly to titles for cases such as a topic titled:
"organisation chart" and a search of "org chart".
If we scoped this wider, all discussion about "org chart" would float to
the top and leave a very common title de-prioritized.
This is a hidden site setting and it has some performance impact due
to double ranking.
That said, performance impact is somewhat mitigated cause ranking on
title alone is a very cheap operation.
Currently `Topic#pm_topic_count` is a count of all personal messages tagged for a given tag. As a result, any user with access to PM tags can poll a sensitive tag to determine if a new personal message has been created using that tag even if the user does not have access to the personal message. We classify this as a minor leak in sensitive information.
With this commit, `Topic#pm_topic_count` is hidden from users by default unless the `display_personal_messages_tag_counts` site setting is enabled.
* FEATURE: allow restricting duplication in search index
This introduces the site setting `max_duplicate_search_index_terms`.
Using this number we limit the amount of duplication in our search index.
This allows us to more correctly weight title searches, so bloated posts
don't unfairly bump to the top of search results.
This feature is completely disabled by default and behind a site setting
We will experiment with it first. Note entire search index must be rebuilt
for it to take effect.

A while back the definition of TL was changed but many
areas in the codebase still use the term 'Regular user'
despite it having some implicit meaning (TL2).
See 20140905055251_rename_trust_level_badges.rb
Many users seems surprised by prefix matching in search leading to
unexpected results.
Over the years we always would return results starting with a search term
and not expect exact matches.
Meaning a search for `abra` would find `abracadabra`
This introduces the Site Setting `enable_search_prefix_matching` which
defaults to true. (behavior unchanged)
We plan to experiment on select sites with exact matches to see if the
results are less surprising
This will allow us more granular control over changing a topic status.
For example you can now force the scope to only allow closing topics in
a specific category. This means that the same scope can't be used to
re-open topics, or close topics in a different category.
In dev/prod, these are absorbed by unicorn. Most commonly, they occur when a client interrupts a message-bus long-polling request.
Also reverts the EPIPE workaround introduced in 011c9b9973
This commit allows us to set the channel slug when creating new chat
channels. As well as this, it introduces a new `SlugsController` which can
generate a slug using `Slug.for` and a name string for input. We call this
after the user finishes typing the channel name (debounced) and fill in
the autogenerated slug in the background, and update the slug input
placeholder.
This autogenerated slug is used by default, but if the user writes anything
else in the input it will be used instead.
Currently, `Tag#topic_count` is a count of all regular topics regardless of whether the topic is in a read restricted category or not. As a result, any users can technically poll a sensitive tag to determine if a new topic is created in a category which the user has not excess to. We classify this as a minor leak in sensitive information.
The following changes are introduced in this commit:
1. Introduce `Tag#public_topic_count` which only count topics which have been tagged with a given tag in public categories.
2. Rename `Tag#topic_count` to `Tag#staff_topic_count` which counts the same way as `Tag#topic_count`. In other words, it counts all topics tagged with a given tag regardless of the category the topic is in. The rename is also done so that we indicate that this column contains sensitive information.
3. Change all previous spots which relied on `Topic#topic_count` to rely on `Tag.topic_column_count(guardian)` which will return the right "topic count" column to use based on the current scope.
4. Introduce `SiteSetting.include_secure_categories_in_tag_counts` site setting to allow site administrators to always display the tag topics count using `Tag#staff_topic_count` instead.
Specifying wildcard characters which also happen to be regex
meta characters for `auto_approve_email_domains`, `allowed_email_domains`
and `blocked_email_domains` site settings currently breaks email
validation.
This change prevents these characters from being specified for these
site settings. It does this by switching the site setting type
from `list` to `host_list`. The `host_list` validator checks for these
characters.
In addition, this change also improves the site setting descriptions and
introduces a migration to fix existing records.
This was previously disabled because of incompatibility with the ember-cli proxy. This commit fixes that incompatibility, and restores the development behaviour to match production.
There were three issues at play:
1. Our bootstrap-js addon handles the forwarding of most requests in the ember-cli proxy. This is not built to handle streaming responses. Solution: skip our custom request processing for `/message-bus/*` and use ember-cli's default `http-proxy`.
2. The request/response size-limiting middleware (`rawMiddleware`) would apply even to unhandled paths, causing request and response bodies to be buffered. Solution: skip it for any paths which are not handled by our custom addon.
3. Expressjs servers will buffer/compress responses. Solution: add `Cache-Control: no-transform` to message-bus responses. For now I've done this in development only, but it may be useful to add it to message-bus's default headers in future
The `enable_new_notifications_menu` site setting allows sites that have
`navigation_menu` set to `legacy` to use the redesigned notifications
menu before switching to the new sidebar navigation menu.
This patch introduces a cookies rotator as indicated in the Rails
upgrade guide. This allows to migrate from the old SHA1 digest to the
new SHA256 digest.
There are various performance issues with the Canvas in iOS Safari
that are causing crashes when processing images with spikes of over 100%
CPU usage. The cause of this is unknown, but profiling points to
CanvasRenderingContext2D.getImageData() and
CanvasRenderingContext2D.drawImage().
Until Safari makes some progress with OffscreenCanvas or other
alternatives we cannot support this workflow. We will revisit in 6
months.
This is gated behind the hidden `composer_ios_media_optimisation_image_enabled`
site setting for people who really still want to try using this.
This feature is stable enough now to make it the default going forward
for new sites. Existing sites that have not yet set enable_experimental_hashtag_autocomplete
to `true` will have it set to `false` for their site settings, which was the old default.
