* This is to prevent user's timezones being changed accidentally
e.g. by admin looking at a user
* This problem only occurred via the user card, however the user card
was still calling userTimezone even if the setting to display user
time in card was disabled
There were two constants here, `INLINE_ONEBOX_LOADING_CSS_CLASS` and
`INLINE_ONEBOX_CSS_CLASS` that were both longer than the strings they
were DRYing up: `inline-onebox-loading` and `inline-onebox`
I normally appreciate constants, but in this case it meant that we had
a lot of JS imports resulting in many more lines of code (and CPU cycles
spent figuring them out.)
It also meant we had an `.erb` file and had to invoke Ruby to create the
JS file, which meant the app was harder to port to Ember CLI.
I removed the constants. It's less DRY but faster and simpler, and
arguably the loss of DRYness is not significant as you can still search
for the `inline-onebox-loading` and `inline-onebox` strings easily if
you are refactoring.
We now show an options gear icon next to the bookmark name.
When expanded we show the "delete bookmark when reminder sent" option. The value of this checkbox is saved in local storage for the user.
If this is ticked, when a reminder is sent for the bookmark the bookmark itself is deleted. This is so people can use the reminder functionality by itself.
Also remove the blue alert reminder section from the "Edit Bookmark" modal as it just added clutter, because the user can already see they had a reminder set:
Adds a default false boolean column `delete_when_reminder_sent` to bookmarks.
Update sinon.js to 9.0.2 to access async fake timers https://sinonjs.org/releases/v9.0.2/fake-timers/ which can then be used with acceptance tests (previously useFakeTimers didn't work with await, e.g. for visit).
Fix the bookmark acceptance test that was time based to use these new fake timers.
Add a fakeTime function that uses moment and the provided date string + timezone to freeze time using useFakeTimers and return a clock.
Add a timeStep function that accepts a clock from fakeTime and a function to run. Once the function is run we call clock.tickAsync(1000) to progress the fake clock forward 1s to progress promises/callbacks.
- 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
We were sharing `Discourse` both as an application object and a
namespace which complicated things for Ember CLI. This patch
moves raw templates into `__DISCOURSE_RAW_TEMPLATES` and adds
a couple helper methods to create/remove them.
If the user chooses "Later Today" as the reminder for a bookmark, then edits that bookmark, we should pre-select "Later Today" if that time has not changed (e.g. later is still 6pm). We do this to avoid confusion instead of opening the custom date + time section.
* Do not show confirmation modal if deleting bookmark from list unless the bookmark has a reminder
* Remove the deleted bookmark from the in-memory array for the user list so a full reload of the list is not needed and scrolling is maintained
This will make a few minor improvements to the second factor user interface. Highlights include:
- Using the site's title to prefix the backup code filename. If non-ascii characters are detected, then prefix "discourse" instead.
- Add icons and change the text on some of the buttons for better clarity and consistency
- Add an education link to the security key modal
* FEATURE: add category banner for why a user cannot post
Adds a category banner for why a user is unable to post in a category.
Also adds an extra alert for the user when a user is unable to create a topic in a
category and they still try and click on the disabled-looking new topic
button.
* Rename all instances of bookmarkWithReminder and bookmark_with_reminder to just bookmark
* Delete old bookmark code at the same time
* Add migration to remove the bookmarkWithReminder post menu item if people have it set in site settings
* Bookmarks with reminders is a core feature now, no need to have a separate URL
* Keep around the old /u/:username/activity/bookmarks-with-reminders route for backwards compat in Ember but just redirect to user activity bookmarks.
For clarity and to save space remove the timezone in brackets e.g. (EDT) from the user card. Also add a title to the user time span to say it is Local Time.
The local time was not updating between user cards because the computed property was not used correctly.
There's an old saying in Tennessee — I know it's in Texas, probably in Tennessee — that says, fool me once computed properties, shame on — shame on you. Fool me — you can't get fooled again.
This adds a site setting (default off) to optionally show a user's local time and timezone in their user card. For example, I live in Brisbane, and if at 3:30PM my time I were to open a user who lives in California's card I would see 22:30 (PST).
* FEATURE: don't display new/unread notification for muted topics
Currently, even if user mute topic, when a new reply to that topic arrives, the user will get "See 1 new or updated topic" message. After clicking on that link, nothing is visible (because the topic is muted)
To solve that problem, we will send background message to all users who recently muted that topic that update is coming and they can ignore the next message about that topic.
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
Currently, when category or tag is muted, only after hard refresh, these new muted categories are really muted. Without a hard refresh, you will still receive "new topic" messages.
Therefore, when tag or category is muted, we should update the user object right away.
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.
Users can now edit the bookmark name and reminder time from their list of bookmarks.
We use "Custom" for the date and time in the modal because if the user set a reminder for "tomorrow" then edit the reminder "tomorrow", the definition of what "tomorrow" is has changed.
* Show the correct bookmark with clock icon when topic-level bookmark reminder time is set and show the time of the reminder in the title on hover.
* Add a new bookmark lib and reminder time formatting function to show time with today/tomorrow shorthand for readability. E.g. tomorrow at 8:00am instead of Apr 16 2020 at 8:00am. This only applies to today + tomorrow, future dates are still treated the same.
* Extend cutoff time for "Later Today" to 5pm
* users can now use the Later Today option up until 5PM
* the time for later today maxes out at 6pm, so any time
it is used after 3pm it is maxed to 6pm
* round to hour instead of half-hour for Later Today as well
* Rounding time bugfix
Refactor plugin-api `addKeyboardShortcut` to point to `KeyboardShortcuts`.
* Do not add shortcuts to the default object directly.
* Create an addShortcut function in keyboard-shortcuts to add shortcuts safely and call to bindKey to be able to use opts.
* Refactor controllers/bookmark.js to use new addShortcut func and emove unnecessary addBindings.
* No longer export keyboard shortcut bindings, rename to DEFAULT_BINDINGS and remove export, these do not need to be accessed by anything else.
If the feature is enabled, staff members can construct a URL and publish a
topic for others to browse without the regular Discourse chrome.
This is useful if you want to use Discourse like a CMS and publish
topics as articles, which can then be embedded into other systems.
Fixes to the quote feature. Most important changes listed below:
* FIX: Correctly attribute quotes when using Reply button
* FIX: Correctly attribute quotes when using replyAsNewTopic
* FIX: Allow quoting a quote
* FIX: Correctly mark quotes as "full"
* FIX: Don't try to create a quote if it's empty
* DEV: Remove an obsolete method `loadQuote`
It isn't used in core anymore, the only use in core has been removed over 4 years ago in 3251bcb. It's not used in any plugins in all-the-plugins and all references to it on GitHub are from outdated forks (https://github.com/search?q=%22Post.loadQuote%22&type=Code)
* DEV: Support for `onChange` on `{{text-field}}`
This will automatically be debounced and only fired when the value
changes.
There is also `onChangeImmediate` which is not debounced in case you
need that, but in almost all cases when observing text in an element you
should debounce.
* Add cancel for timer
New Reminder Types
-------------------------------------
* Add a "later this week" reminder which is today + 2 days, will not show if we are on the days Thu-Sun
* Add a "start of next business week" reminder which is 8am Monday
Bugfixes and Tweaks
--------------------------------------
* Move dates out of translation for reminder types and yield HTML for tap-tile for more customizable content and styling
* Make sure double clicking the bookmark icon in quick access takes users to the new bookmarks-with-reminders page
* Sane default to 8am (start of day) for custom reminder with no time
Introduce the concept of "high priority notifications" which include PM and bookmark reminder notifications. Now bookmark reminder notifications act in the same way as PM notifications (float to top of recent list, show in the green bubble) and most instances of unread_private_messages in the UI have been replaced with unread_high_priority_notifications.
The user email digest is changed to just have a section about unread high priority notifications, the unread PM section has been removed.
A high_priority boolean column has been added to the Notification table and relevant indices added to account for it.
unread_private_messages has been kept on the User model purely for backwards compat, but now just returns unread_high_priority_notifications count so this may cause some inconsistencies in the UI.
Usage:
```
{{d-button icon="times" label="foo.bar" isLoading=true}}
```
Note that a button loading without an icon will shrink text size to prevent button to jump in size.
A button while loading is disabled.
Even though `type` is an alias for `method`, we have custom logic in `/discourse/lib/ajax` that checks only `type`, and ~200 other ajax calls in the codebase already use `type` param.
This set of tests cleared the emoji store *before* each test, while the other set - *after*. So if these were run first, they would break a single test from the other set.
Based on issues identified in https://meta.discourse.org/t/improved-bookmarks-with-reminders/144542/20
* Implement the resolvedTimezone() function on the user model where we return the user's timezone if it has been set, or we guess it using moment and save it to the user using an update call if it has not yet been set. This covers the cases of users who do not log out/in often who will not get their timezone set via login. This also makes sure the guess + save is done in a non-obtrusive way not on every page -- only when it is needed.
* Before if a user's timezone was blank when they visited their profile page we were autofilling the dropdown with the guessed timezone from moment. However this was confusing as it would appear you have that timezone saved in the DB when you really didn't. Now we do not autofill the dropdown and added a button to automatically guess the current timezone to make everything more explicit.
Limitations: the user profile "open external links in new tab setting" is
slightly broken for "External URL" permalinks.
Remove the copy from the admin permalinks page stating that this doesn't work.
Based on reports here https://meta.discourse.org/t/improved-bookmarks-with-reminders/144542
* Because the `userHasTimezone` property was computed and we were checking on an (essentially) global object, ember was not aware that the user timezone had changed because it changed in a different place. instead set the timezone as internal state for the modal on show and base the computed property off of that so it mutates correctly
* The tap-tile components were in the admin folder completely unnecessarily, move them out into the main discourse folder otherwise noone else can use the new bookmarks (icon + text is missing)
* Cosmetic fixes for the bookmark modal
* Do not show "later today" when the later time will be > 5pm
* When a custom reminder time is selected, store it in localStorage. The next time the modal is opened, if the last datetime is > now, then a new tile with "Last" will be shown that lets the user reselect that same time.
* Also add an explicit "No Reminder" option that is selected by default
This pr replaces `{{{ }}}` usage by a {{html-safe}} helper. While it doesn't solve the underlying issue, it gives us a path forward without risking breaking too much existing behavior.
Also introduces an htmlSafe computed macro:
```
import { htmlSafe } from "discourse/lib/computed";
htmlDescription: htmlSafe("description")
```
Overtime {{html-safe}} usage should be removed and moved to components properties or specialized components/helpers.

Pop up a confirmation box when there is input. This prevents accidental closing
of the dialog boxes due to clicking outside.
This adds a development hook on modals in the form of a `beforeClose`
function. Modal windows can abort the close if the funtion returns false.
Additionally fixing a few issues with loop and state on the modal popups:
Escape key with bootbox is keyup.
Updating modal to close on keyup as well so escape key is working.
Fixes an issue where pressing esc will loop immediately back to the modal by:
keydown -> bootbox -> keyup -> acts as "cancel", restores modal
Needs a next call to reopenModal otherwise, keyup is handled again by the modal.
Fixes an issue where pressing esc will loop immediately back to the confirm:
esc keyup will be handled and bubble immediately back to the modal.
Additionally, only handle key events when the #discourse-modal is visible.
This resolves issues where escape or enter events were being handled by
a hidden modal window.

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.

* The data-orig-src attribute was not being removed from cooked
video and audio so the composer was infinitely trying to get the
URLs for them, which would never resolve to anything
* Also the code that retrieved the short URL was unscoped, and was
getting everything on the page. if running from the composer we
now scope to the preview window
* Also fixed a minor issue where the element href for the video

This change both improves readability and fixes potential race-condition issues where promises were nested instead of being chained.
Also includes:
* Use arrow functions and Promise shorthands
* Remove the obsolete `asyncTestDiscourse` helper
* FIX: Add aria-labels to topic list items
Before this fix you could navigate the topic list using a screen reader
and a keyboard but some of the items were not as descriptive as they
could be. The newly added labels make it easier to understand what you

This commit also fixes a deprecation warning as the previous component was overriding a computed property from the group model.
Finally a test has been added as this is the only place where we use list-setting outside of the settings, this was highly subject to regressions.
* Also fixes an issue where if webp was a downloaded hotlinked
image and then secure + sent in an email, it was not being
redacted because webp was not a supported media format in
FileHelper
* Webp originally removed as an image format in
https://github.com/discourse/discourse/pull/6377
and there was a spec to make sure a .bin webp
file did not get renamed from its type to webp.
However we want to support webp images now to make
sure they are properly redacted if secure media is
on, so change the example in the spec to use tiff,
another banned format, instead
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.
This confuses me every time I run qunit tests in the browser. The tab is labelled Meta, but it's not meta! This change has no functional impact on the tests
Styling based on element-ids, it is impossible for themes/plugins to display multiple cards on a single page. Using classes is a more flexible approach. The element-ids are maintained for backwards compatibility with existing plugins/themes.
### 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).
Meta topic: https://meta.discourse.org/t/secure-media-uploads-expire/140894
This fixes the issue where if secure media was enabled, audio
and video files would do an initial load using the presigned
URL for the media to get metadata information e.g. duration of
track/video. However this started the expiry countdown for the
URL, so when a user pressed play on the media after 15 seconds
the media would be expired and AWS would return a 403 error.
We do not preload media if secure media is enabled. Otherwise
we just set the preload type to "metadata" which is the browser
default anyway.
* FIX: Properly convert quotes to Markdown
When quoting a quote it used to convert the quote header, including the
user avatar and username, into a image and some text and then the
contents. This also caused issues when quoting full paragraphs (or when
selecting paragraphs by triple-clicking) because the user avatar and
name from the following quote would also be included.
This commit implements the support necessary to convert
<aside class="quote"> elements to proper Discourse quotes.
Commit aa24be1 made it possible to build data attributes from image's
Markdown and this changes ensure that the resize controls still work
when data attributes are present.
This also enables`@action` use in plugin connectors.
Setting `actions` earlier allows `setupComponents` to use them, for example, when setting up event listeners.
This new iteration of select-kit focuses on following best principales and disallowing mutations inside select-kit components. A best effort has been made to avoid breaking changes, however if you content was a flat array, eg: ["foo", "bar"] You will need to set valueProperty=null and nameProperty=null on the component.
Also almost every component should have an `onChange` handler now to decide what to do with the updated data. **select-kit will not mutate your data by itself anymore**
For consistency this PR introduces using custom markdown and short upload:// URLs for video and audio uploads, rather than just treating them as links and relying on the oneboxer. The markdown syntax for videos is  and for audio it is .
This is achieved in discourse-markdown-it by modifying the rules for images in mardown-it via md.renderer.rules.image. We return HTML instead of the token when we encounter audio or video after | and the preview renders that HTML. Also when uploading an audio or video file we insert the relevant markdown into the composer.
Let's say post #2 quotes post number #1. If a user decides to quote the
quote in post #2, it should keep the information of post #1
("user_1, post: 1, topic: X"), instead of replacing with current post
info ("user_2, post: 2, topic: X").
jquery.autoellipsis tries to automatically find the available space
which depends on multiple factors which may differ between the machines
where the tests are running.

* DEV: Simplify `default as` imports
Co-authored-by: Joffrey JAFFEUX <j.jaffeux@gmail.com>
This breaking change was originally a deprecation fix for overriding a computed property `none`.
There are 4 uses of `rootNone` in core and "all-the-plugins":
1. in discourse-chat-integration, admin-plugins-chat-edit-rule.hbs - changed behavior, that I'd consider a fix - `rootNoneLabel` is now used regardless of `siteSettings.allow_uncategorized_topics` value, which I believe was an originally intended behavior (i.e. it most likely hasn't been tested with disabled uncategorized topics)
2. in discourse-slack-official, plugins-slack.hbs - the same as 1.
3. in core, edit-category-general.hbs (in this PR) - no change in behavior
4. in discourse-googlebooks, edit-category-general.hbs - no change in behavior (since `allowUncategorized="true"` is also passed as an argument)

Plugins like https://github.com/discourse/discourse-calendar add extra HTML (e.g. icons) to user/group mentions. Clicking on those extra elements used to only flash a blank card. Now, the card opens properly.

runAllTests is an async function, so the try/catch block does not help. The function always returns a promise, so we need to use `.catch` to handle errors. Previously, raised errors were ignored, and the process continued running until it timed out.
Note: All of this functionality is hidden behind a hidden, default false, site setting called `enable_bookmarks_with_reminders`. Also, any feedback on Ember code would be greatly appreciated!
This is part 1 of the bookmark improvements. The next PR will address the backend logic to send reminder notifications for bookmarked posts to users. This PR adds the following functionality:
* We are adding a new `bookmarks` table and `Bookmark` model to make the bookmarks a first-class citizen and to allow attaching reminders to them.
* Posts now have a new button in their actions menu that has the icon of an actual book
* Clicking the button opens the new bookmark modal.
* Both name and the reminder type are optional.
* If you close the modal without doing anything, the bookmark is saved with no reminder.
* If you click the Cancel button, no bookmark is saved at all.
* All of the reminder type tiles are dynamic and the times they show will be based on your user timezone set in your profile (this should already be set for you).
* If for some reason a user does not have their timezone set they will not be able to set a reminder, but they will still be able to create a bookmark.
* A bookmark can be deleted by clicking on the book icon again which will be red if the post is bookmarked.
This PR does NOT do anything to migrate or change existing bookmarks in the form of `PostActions`, the two features live side-by-side here. Also this does nothing to the topic bookmarking.
But the "synonyms" can't use the TagSerializer yet. We still have some
code from the discourse-tagging plugin that uses "text" instead of
"name", "count" instead of "topic_count", etc. We should make the js
consistent with the TagSerializer and then stop using tag_counts_json.
Fixes an issue where updates to the first post in a topic would be visible only for staff.
Before, because the empty tag would find its way to `PostRevisor`, `TopicsController#update` would create a hidden revision, and later `PostsController#update` would only update that revision.
After this change, `TopicsController` doesn't create a revision at all (unless necessary), so `PostsController` can create it (and correctly decide whether the revision should be hidden or not).
* DEV: Add API to alter uploads Markdown
* DEV: Extract data attributes from image / download Markdown
For example '[test|attachment|hello=world]' will generate an 'a' element
with a data attribute: 'data-hello=world'.
This commit also makes MarkdownIt to transform '|attachment' into
'class="attachment"'. This transformation used to be a part of the
process which resolves short URLs (i.e. upload://).
* DEV: Export imageNameFromFileName
This reapplies commit b643526d9a after
being reverted in commit f65c453555.
Unlike the original commit, this does a single pass and does not take
into account unfinished code blocks.
When uploading an image file with dots in the filename we were splitting the string on dots and getting the last of the split items as the extension-less filename. However this did not work with filenames that have dots. We now just remove the extension using substr.
This feature adds the ability to define synonyms for tags, and the ability to merge one tag into another while keeping it as a synonym. For example, tags named "js" and "java-script" can be synonyms of "javascript". When searching and creating topics using synonyms, they will be mapped to the base tag.
Along with this change is a new UI found on each tag's page (for example, `/tags/javascript`) where more information about the tag can be shown. It will list the synonyms, which categories it's restricted to (if any), and which tag groups it belongs to (if tag group names are public on the `/tags` page by enabling the "tags listed by group" setting). Staff users will be able to manage tags in this UI, merge tags, and add/remove synonyms.
