* FEATURE: Default Composer Category Site Setting
- Create the default_composer_category site setting
- Replace general_category_id logic for auto selecting the composer
category
- Prevent Uncategorized from being selected if not allowed
- Add default_composer_category option to seeded categories
- Create a migration to populate the default_composer_category site
setting if there is a general_category_id populated
- Added some tests
* Add missing translation for the new site setting
* fix some js tests
* Just check that the header value is null
- allows to scroll while hovering the menu
- correctly changes message background color while hovering menu
- prevents a bug where it would sometimes close the menu while moving from menu to the 3 dots expanded dropdown. This was caused by the gap between header/body of the 3 dots dropdown, which would sometimes allow to create a mouseover event on a possible different underlying message
- removes recent/favorite reactions on drawer mode
- grayscale reactions until hover
- boxshadow on msgactions container
- removes useless code
Add the ability to modify a selectKit's content with `replaceContent`
Eg.
```
api.modifySelectKit("combo-box").replaceContent(() => {
return {
id: "foo",
name: "Foo",
};
});
```
will override existing content to only include the passed object
This PR enables the [`no-action-modifiers`](https://github.com/ember-template-lint/ember-template-lint/blob/master/docs/rule/no-action-modifiers.md) template lint rule and removes all usages of the `{{action}}` modifier in core.
In general, instances of `{{action "x"}}` have been replaced with `{{on "click" (action "x")}}`.
In many cases, such as for `a` elements, we also need to prevent default event handling to avoid unwanted side effects. While the `{{action}}` modifier internally calls `event.preventDefault()`, we need to handle these cases more explicitly. For this purpose, this PR also adds the [ember-event-helpers](https://github.com/buschtoens/ember-event-helpers) dependency so we can use the `prevent-default` handler. For instance:
```
<a href {{on "click" (prevent-default (action "x"))}}>Do X</a>
```
Note that `action` has not in general been refactored away as a helper yet. In general, all event handlers should be methods on the corresponding component and referenced directly (e.g. `{{on "click" this.doSomething}}`). However, the `action` helper is used extensively throughout the codebase and often references methods in the `actions` hash on controllers or routes. Thus this refactor will also be extensive and probably deserves a separate PR.
Note: This work was done to complement #17767 by minimizing the potential impact of the `action` modifier override, which uses private API and arguably should be replaced with an AST transform.
This is a followup to #18333, which had to be reverted because it did not account for the default treatment of modifier keys by the {{action}} modifier.
Commits:
* Enable `no-action-modifiers` template lint rule
* Replace {{action "x"}} with {{on "click" (action "x")}}
* Remove unnecessary action helper usage
* Remove ctl+click tests for user-menu
These tests now break in Chrome when used with addEventListener. As per the comment, they can probably be safely removed.
* Prevent default event handlers to avoid unwanted side effects
Uses `event.preventDefault()` in event handlers to prevent default event handling. This had been done automatically by the `action` modifier, but is not always desirable or necessary.
* Restore UserCardContents#showUser action to avoid regression
By keeping the `showUser` action, we can avoid a breaking change for plugins that rely upon it, while not interfering with the `showUser` argument that's been passed.
* Revert EditCategoryTab#selectTab -> EditCategoryTab#select
Avoid potential breaking change in themes / plugins
* Restore GroupCardContents#showGroup action to avoid regression
By keeping the `showGroup` action, we can avoid a breaking change for plugins that rely upon it, while not interfering with the `showGroup` argument that's been passed.

* FIX: New general category changes preventing topic create
Follow up to: #18383
The logic in the previous commit was checking for null, but we are
seeding the SiteSetting.general_category_id with an id of -1 so we need
to check for a positive value as well as checking for null.
See: https://meta.discourse.org/t/240661
* Add js test for presence of category… dropdown option
* FEATURE: Make General the default category
* Set general as the default category in the composer model instead
* use semicolon
* Enable allow_uncategorized_topics in create_post spec helper for now
* Check if general_category_id is set
* Enable allow_uncategorized_topics for test env
* Provide an option to the create_post helper to not set allow_uncategorized_topics
* Add tests to check that category… is not present and that General is selected automatically
* REFACTOR: Improve reusability by Decoupling flag modal from flag target.
We want chat message's flags to have the same features as topic and posts' flags, but we prefer not having to duplicate core's logic. This PR moves target specific bits to different classes, allowing plugins to flag custom things by
providing their own.
* A couple of fixes for the flag modal:
- Make sure buttons are disabled until a flag type is selected.
- Don't throw an error when checking if the user can undo an action on a deleted topic.
- Disable flagging on deleted topics.
Previously we were calculating both the minimum and maximum widths for
SK dropdowns using this Popper modifier. The max. width calculation was
causing issues with dropdowns in Firefox and was also sluggish when
rendering.
This switches to using CSS calculations for max. widths. It adds a 600px
global maximum and targeted maximums for the category composer dropdown
and the bookmark list dropdowns.
Tags mixin is already filtering a lot of data from the user submitted filter in `createContentFromInput()` which can lead to sk receiving an empty filter while the input actually has a value.
Also, the change in insert-hyperlink (from `this.linkUrl.indexOf("http") === -1` to `!this.linkUrl.startsWith("http")`) was intentional fix: we don't want to prevent users from looking up topics with http in their titles.
- following c3fd91670e `paste` has been typoed into `pase`
- adds two tests for pasting in `multi-select` and `email-group-user-chooser`
- selectKitOptions would not be following the right overriding order
- `category-selector` was using `selectKitOptions` directly which shouldn't be the case as it's not using computed values
- apparently since a recent ember upgrade, paste event is not providing `originalEvent` anymore and `clipboardData` should be retrieved directly on the event
```sh
npx ember-holy-futuristic-template-namespacing-batman-codemod ensure-template-only-has-backing-class
```
We would like to colocate templates but, when no backing class exists, colocated templates extend `templateOnly` instead of `Ember.Component`. Generating the backing class helps avoid any behavioral changes.
We can also run the `tagless-ember-components-codemod` to put the tags into the templates at which point we could convert these back to template-only components.
`email-group-user-chooser` currently handles paste events to allow users to paste multiple entries at once instead of entering them one by one. This behavior makes sense when the component is used in scenarios where it makes sense to provide multiple entries such as the recipients field when creating a PM. However, for instances where the component accepts only 1 entry, it doesn't make a lot of sense to do custom handling of paste events.
This commit makes our paste event handler a NOOP when the component is configured to accept only 1 entry in which case pasting will simply input the value into the component's search field.
When a user is answering a whisper comment, they cannot change from whisper to regular answer.
However, user can click reply to topic. We keep `postSnapshot` so user can change mind and switch back to reply to post. In that case, a toggle whisper button should appear.
To make it happen, I am ensuring to display a toggle whisper button when user is replying to topic - `postLink` attribute is missing.
The values in Discourse dropdown menus only come from admin-defined strings, not unsanitised end-user input, so this lack of escaping was not exploitable.
1. When the select-kit body is rendered, it defaults to being displayed under the triggering select-kit header, unless...
there isn't enough space between the bottom of the select-kit header and the bottom of the viewport
&
there's enough space on top of the select-kit header, and in that case, we render it on top.
2. We give it a bit of padding on top, so it never renders below the header on the Z-axis.
14778ba52e/app/assets/javascripts/select-kit/addon/components/select-kit.js (L877-L884)
3. If there isn't enough space between the bottom of the viewport and the bottom of the select-kit header, and there isn't enough space between its top and the bottom of `d-header`, it renders at the bottom of the select-kit header.
In theory, number 3 above rarely ever happens. However, it can occur in the case of the user preferences page in combination with a large select-kit body (many categories).
The select-kit body then renders below the trigging select-kit header, but it's cut off. Users won't be able to see the entire select-kit body.
Here's an example
a719734d92.mp4
This PR adds a "prevent overflow" modifier to Popper. What it does is that it handles the case above.
If there's not enough space below the select-kit header or above it, render the select-kit body below the select-kit header BUT... anchor it to the bottom of the viewport.
Here's what that looks like
32cd1639bb.mp4
After this fix, even very large select-kit bodies will always be on the screen.
Please note that this PR has no impact on either number 1 or number 2 above, and those will continue to function as they currently do.
The only downside here is that the select-kit body might cover the select-kit header if it needs to be anchored at the bottom of the viewport, and it's very large. However, between that and not being able to see all the options, I think it's a fair compromise. There's only so much space in the viewport.
This PR ignores mobile because we have a different placement strategy. We use `position: absolute`... so, users can scroll the viewport if needed.
Previously we only supported a single 'required tag group' for a category. This commit allows admins to specify multiple required tag groups, each with their own minimum tag count.
A new category_required_tag_groups database table replaces the existing columns on the categories table. Data is automatically migrated.
String.prototype.substr() is deprecated so we replace it with String.prototype.slice() which works similarily but isn't deprecated.

More precisely, if popper can't position something at the bottom, it will automatically attempt to position it at the top. However we should ensure it doesn’t consider the space under the d-header as valid space, when header's height is taken into consideration if top space is not enough, we should force bottom, and flip it back.
This logic is not necessary on modals as the d-header is not present.
Previously, if an admin user tried to add/remove
users to another user's ignored list, it would
be added to their own ignore list because the
controller used current_user. Now for admins only
a source_user_id parameter can be passed through,
which will be used to ignore the target user for
that source user.
The old choose-topic component did not have the same style as the rest
of the create invite modal and was not very suitable to use in the modal
because it introduced the search results in modal's body.
The new topic-chooser is built using select-kit and provides a more
polished user experience.
This makes a small improvement to 'cold cache' ember-cli build times, and a large improvement to 'warm cache' build times
The ember-auto-import update means that vendor is now split into multiple files for efficiency. These are named `chunk.*`, and should be included immediately after the `vendor.js` file. This commit also updates the rails app to render script tags for these chunks.
This change was previously merged, and caused memory-related errors on RAM-constrained machines. This was because Webpack 5 switches from multiple worker processes to a single multi-threaded process. This meant that it was hitting node's default heap size limit (~500mb on a 1GB RAM server). Discourse's standard install procedure recommends adding 2GB swap to 1GB-RAM machines, so we can afford to override's Node's default via the `--max-old-space-size` flag.
This reverts commit f4c6a61855 and a8325c9016
This update of ember-auto-import and webpack causes significantly higher memory use during rebuilds. This made ember-cli totally unusable on 1GB RAM / 2GB swap environments. We don't have a specific need for this upgrade right now, so reverting for now.

This also switches to using the NPM package for better build stability. And adds a clearer label in the alert that is displayed to show your current timezone (when changing timezones).
* FIX: allows more precise placement strategy on mobile
- default to absolute on mobile, fixed on desktop
- allows to set a global `placementStrategy` or a specific to each view `mobilePlacementStrategy` `desktopPlacementStrategy`
This is mainly used to allow a proper composer-actions positioning in mobile.
Note this commit also fixes a mouseDown event which could propagate quote-button event and cause the composer to close full screen on mobile
* mobile only
Before this, if you were composing a new topic and then switched the mode to "New Message", the dropdown would disappear.
So if you changed your mind, you'd have to copy the text you typed, cancel, click "New Topic" again, and then paste the text. (and if you already had a title entered too, things would be more complicated…)
Calling `window.getComputedStyle` during initialization causes the browser to pause and 'Recalculate Style'. On my machine, this adds about 7ms to boot time. Instead, we can check for the `rtl` class on the html element, which is added by the server, and doesn't require computing styles.
* FIX: register customOptions as select kit filter
We are allowing plugins to define custom filters which are added to CUSTOM_USER_SEARCH_OPTIONS const. However, we need to have static placeholder for custom filters, so those props will be passed, and we can use it later.
* fix
* DEV: Use named parameters for dir-span helper
Follow up to: e50a5c0c73
In order to improve code clarity this change introduces named parameters
for the dir-span helper. This is specifically for the new `htmlSafe`
parameter which you can use instead of just passing in a boolean if the
strings you are passing in have already been escaped.
Before: `{{dir-span category.description false}}`
After: `{{dir-span category.description htmlSafe=true}}`
* Set default value for params arg
Major changes included:
- better support for screen readers
- trapping focus in modals
- better tabbing order in composer
- alerts on no content found/number of items found
- better autofocus in modals
- mini-tag-chooser is now a multi-select component
- each multi-select-component will now display selection on one row
We rely on yarn workspaces so we don't want people using npm in the repo by accident.
Also updated the required node version to 12+.
~~Not sure about the min yarn version – the latest one could be missing in various CI-like envs, so I might change it yet.~~
Downgraded yarn to ">= 1.21.1" (the oldest of "current" versions, tagged "legacy")
- inlines dasherize helper in sk
- uses an ajax helper to load wizard's ajax lib when in wizard
- amends wizard's ajax lib to work with string as first arg
- disabled loading spinner in wizard as it's not available
Both of the commits in this PR are meant to fix the problem of invalid
option being shown in the flair chooser. An invalid option can be shown
if at some point it was a valid one - a group with a flair that was
later changed by an admin and flair was removed. The other option an
invalid option can be selected is if the user had a primary group when
the migration ran and copied the same value to the flair_group_id
column.
* FIX: Set flair_group_id only if group has flair
Follow up to 4ba93aac66.
* FIX: Do not show invalid option in flair chooser
If selected flair group became unavailable because the flair was removed
then the option would still be selected and visible as an ID only.
User flair was given by user's primary group. This PR separates the
two, adds a new field to the user model for flair group ID and users
can select their flair from user preferences now.
…and just prioritize the current one, instead of hiding other categories.
Context: when you open the composer by clicking "New Topic" button when in a category, or by clicking "New Topic" in the share-popup, the category selector shows only the current category and its children (and "Uncategorized"). You can still find other categories, but you have to search by name.
This PR changes that, so you now can see all the categories in the dropdown, and those that are relevant (again: current, children and uncategorized) are displayed before all other categories.
tldr: don't make choosing other categories harder - make choosing relevant ones easier.
1. It defaults to `cache: true` already
2. Setting it to `false` for non-GET request doesn't do anything
3. We were correcting `cache: false` GET requests to use `cache: true`
…so setting it to anything at all, for any type of request doesn't make sense (anymore)
Over the years we accrued many spelling mistakes in the code base.
This PR attempts to fix spelling mistakes and typos in all areas of the code that are extremely safe to change
- comments
- test descriptions
- other low risk areas
The user may have changed their category or tag tracking settings since a topic was tracked/watched based on those settings in the past. In that case we need to alter the reason message we show them otherwise it is very confusing for the end user to be told they are tracking a topic because of a category, when they are no longer tracking that category.
For example: "You will see a count of new replies because you are tracking this category." becomes: "You will see a count of new replies because you were tracking this category in the past."
To do this, it was necessary to add tag and category tracking info to current user serializer. I improved the serializer code so it only does 3 SQL queries instead of 9 to get the tracking information for tags and categories for the current user.
There is a category setting that enforces 1 or more tags must be added to a topic from a specific tag group before creating it. This validation was not being run before the topic was being sent to a review queue for categories that have that setting enabled.
There was an existing validation in `TopicCreator` but it was not correct; it was only validating when the tags did _not_ exist and also only happened on `create`. I now run the validation in `TopicCreator.valid?`
I also improved the error message shown to the user when they have not added the tags required (showing the tag names from the tag group), and changed the composer tag selector to not show "optional" if there are N tags required from a certain group.
On some modals the main/primary input field is a select-kit component (like `{{email-group-user-chooser}}` on the assign modal), so it makes sense to allow select-kit to steal focus on modals like these. This PR adds an `autofocus` option (default false) that allows select-kit to steal focus when it's rendered.
`{{user-selector}}` is now deprecated and it will be removed from core in Discourse 2.8. All instances of `{{user-selector}}` has been replaced with `{{email-group-user-chooser}}`.
It was introduced in c82b2dcc24, but since b76731d722 and 58ee947b35 it's a single-option dropdown, so there's no need to show it (and keep it) instead of a button. We use a button for non-admins already.
This PR revamps the topic timer UI, using the time shortcut selector from the bookmark modal.
* Fixes an issue where the duration of hours/days after last reply or auto delete replies was not enforced to be > 0
* Fixed an issue where the timer dropdown options were not reloaded correctly if the topic status changes in the background (use `MessageBus` to publish topic state in the open/close timer jobs)
* Moved the duration input and the "based on last post" option from the `future-date-input` component, as it was only used for topic timers. Also moved out the notice that is displayed which was also only relevant for topic timers.
This PR is the first step towards replacing our `{{user-selector}}` and eventually deprecating and removing it from our codebase. Some of `{{user-selector}}` problems are:
1. It's called `{{user-selector}}`, but in reality in can also select groups and emails.
2. It's an Ember component, yet it doesn't have a handlebars template and uses jQuery to render itself and modify the DOM. An example of this problem is when you want to clear the selected users programmatically, see [this](6c155dba77/app/assets/javascripts/discourse/app/components/user-selector.js (L179-L185)).
3. We now have select kit which does very similar things but a lot better.
This PR introduces `{{email-group-user-chooser}}` which is meant to replace `{{user-selector}}`. It extends select kit and has the same features that `{{user-selector}}` has. `{{user-selector}}` is still used in a few places in core, but they'll all be replaced with the new component in a separate commit.
Once `{{user-selector}}` is not used anywhere in core, it'll be deprecated and then removed after the 2.7 release.
We want to wrap the `Ember.run.debounce` function and internally call `Ember.run` instead when running tests.
This commit changes discourseDebounce to work the same way as `Ember.run.debounce`.
Now that `discourseDebounce` works exactly like `Ember.run.debounce`, let's replace it and only use `DiscourseDebounce` from now on.
Move debounce to discourse-common to be able to reuse it in different bundles
Keep old debounce file for backwards-compatibility
A small change that would allow components to extend the tag
display in the filter dropdown, like they can in other contexts.
Was requested in the tag icons component, see
https://meta.discourse.org/t/tag-icons-component/109757/60?u=pmusaraj
The PR also standardises tag styling in select-kit dropdowns.
Paths prefixed with /tag/ are exclusively for when the tag name is the
next string in the path. Therefore, when a category is being used as
context, the path should start with /tags/ instead.
After 5fc239b535, the category dropdown
was showing "undefined" for the "all-categories" and "no-categories"
messages. This commit introduces a check to run the HTML parser only if
we're dealing with a real category, which fixes the above issue.
This commit is also moving one test to a component test.
A followup to this commit would be to ensure every dropdowns are using a regex instead of the normalize/lowercase system we have now.
eslint --fix is capable of fix it automatically for you, ensure prettier is run after eslint as eslint --fix could leave the code in an invalid prettier state.
It didn't provide much value to users as it often didn't match the number visible in the topic timeline. That's because `postNumber` is an implementation detail, while the timeline counts only full visible posts (no whispers, topic action notices, etc.)
* REFACTOR: reworks all the search-advanced-options panel
This commit includes the following changes:
- prevents any mutation of external (to the component) values
- get rid of observers
- uses @action
- minor UI tweaks
- dropped the unecessary debounce
- drops all the legacy code for badges/groups which is not being used
- replaces user-selector by user-chooser and improves multi-select to not show `search` if maximum has been reached
Most importantly this refactor should fix multiple bugs due to _update() being called multiple times if searchTerm was empty and other various bugs where some changes in searchTerm was not applied to the sidebar.
* DEV: Move `Discourse.getURL` and related functions to a module
* DEV: Remove `Discourse.getURL` and `Discourse.getURLWithCDN`
* FIX: `get-url` is required for server side code
* DEV: Deprecate `BaseUri` too.
* DEV: `Discourse.baseUri` does not exist
This never could have worked - should have been `Discourse.BaseUri` if
anything.
* DEV: Remove Discourse.Environment
* DEV: Remove `Discourse.disableMissingIconWarning`
* DEV: A bunch more missing environment checks
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)

- reduces the API to 3 actions for now: appendContent/prependContent/onChange
- well tested
- removes all previous APIS which were only half supported or too dangerous as they could collide with other plugins or core behaviors
- this plugins also puts every sk test helpers in one file
A large topic page will always have the bottom tracking button, and will also have the timeline, meaning we already had 2 tracking events.
But it gets even worse when you know that the timeline button is a component connector which will trigger `didInsertElement` very frequently, meaning we were constantly adding more and more appEvents handlers.
Previously we relied on race conditions to correctly open a draft, so this
broke.
New code is deliberate.
Also corrects missing observers on composer action
