This reverts commit 20780a1eee.
* SECURITY: re-adds accidentally reverted commit:
03d26cd6: ensure embed_url contains valid http(s) uri
* when the merge commit e62a85cf was reverted, git chose the 2660c2e2 parent to land on
instead of the 03d26cd6 parent (which contains security fixes)
* FIX: Emit web hooks for flags
* FEATURE: Remove 'flag' web hook in favor of 'reviewable' web hook
* FEATURE: Remove 'queued post' web hook in favor of 'reviewable' web hook
* FIX: Do not set a default value for web hooks with no events
* the post_actions table has no FK to users, so if a user has been
deleted we may end up with dangling post_action records, which then
interferes with the bookmarks migration because bookmarks DO have
an FK to users
* PERF: Dematerialize topic_reply_count
It's only ever used for trust level promotions that run daily, or compared to 0. We don't need to track it on every post creation.
* UX: Add symbol in TL3 report if topic reply count is capped
* DEV: Drop user_stats.topic_reply_count column
It was using ActiveRecord which broke migrating a new site. The groups
table now has a unique constraint on group name so this migration from
2014 should not be necessary anymore.
Previously we only changed sequence on ownership change, this
cause a race condition between tabs where user could type for a
long time without being warned of an out of date draft.
This change is a radical change and we should watch closely.
Code was already in place to track sequence on the client so no
changes are needed there.
posts and topics tables can be huge, this migration change
ensures the migration performs less work in one giant transaction
reducing risk of deadlocks
Migration is re-runnable thanks to NOT EXISTS checks
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.
When using pgbouncer without a transaction, it's possible for the connection to change between statements in a migration. Instead, create a real table, and drop it when the migration is finished
This introduces new APIs for obtaining optimized thumbnails for topics. There are a few building blocks required for this:
- Introduces new `image_upload_id` columns on the `posts` and `topics` table. This replaces the old `image_url` column, which means that thumbnails are now restricted to uploads. Hotlinked thumbnails are no longer possible. In normal use (with pull_hotlinked_images enabled), this has no noticeable impact
- A migration attempts to match existing urls to upload records. If a match cannot be found then the posts will be queued for rebake
- Optimized thumbnails are generated during post_process_cooked. If thumbnails are missing when serializing a topic list, then a sidekiq job is queued
- Topic lists and topics now include a `thumbnails` key, which includes all the available images:
```
"thumbnails": [
{
"max_width": null,
"max_height": null,
"url": "//example.com/original-image.png",
"width": 1380,
"height": 1840
},
{
"max_width": 1024,
"max_height": 1024,
"url": "//example.com/optimized-image.png",
"width": 768,
"height": 1024
}
]
```
- Themes can request additional thumbnail sizes by using a modifier in their `about.json` file:
```
"modifiers": {
"topic_thumbnail_sizes": [
[200, 200],
[800, 800]
],
...
```
Remember that these are generated asynchronously, so your theme should include logic to fallback to other available thumbnails if your requested size has not yet been generated
- Two new raw plugin outlets are introduced, to improve the customisability of the topic list. `topic-list-before-columns` and `topic-list-before-link`
* 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.
We need to recreate the badge_posts view each time we change
column on the posts table.
The p.* is auto expanded on view create, cascade should not have
been used
avg_time on posts and topics have not been used in a year.
This uses a re-runnable ddl transaction diasabled migration to
drop the column, cause it touchs very high traffic table and may
deadlock
* 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
Make sure the topic_user.bookmarked column is set correctly when user bookmarks/unbookmarks any post in a topic. For example, you bookmarked a post in the topic that was not the OP, the bookmark icon in the topic list would not be shown. Same if deleting a bookmark for the last bookmarked post in a topic, the bookmark icon in the topic list would not be removed.
Previously this was only setting it to true if bookmarking the OP/topic, which was not correct -- we want to show the icon on the topic list if any post is bookmarked.
Also set to false if unbookmarking the last bookmarked post in the topic.
Also in this PR is a migration to correct any out of sync topic_user.bookmarked columns, based on the new logic.
This reverts commit 6f9177e2ed.
We decided on a completely different approach to the problem.
Instead we will let blocked emails be treated as canonical.
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
* FEATURE: Add created_at column to user_badges
This makes scraping for newly granted badges easier.
Patch from @eviltrout applied.
Co-authored-by: Robin Ward <robin.ward@gmail.com>
In development and test mode you don't care about email domains. Now
that `rake db:migrate` outputs a lot less this felt like an error when
it's really a warning.
The new `enforce_canonical_emails` site setting ensures that emails in the
canonical form are unique.
This mean that if `s.a.m+1@gmail.com` is registered `sam@gmail.com` will
not be allowed.
The commit contains a blanket "tag strip" (stripping everything after +)
it also contains special handling of a "dot strip" for googlemail and gmail.
The setting only impacts new registrations after `enforce_canonical_emails`
The setting is default false so it will not impact any existing installs.
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.
Some DBs failed on this migration, possibly due to new records being added, with the error
ActiveRecord::NotNullViolation: PG::NotNullViolation: ERROR: column "high_priority" contains null values
Luckily, the migration is retryable as is.
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.
* This PR implements the scheduling and notification system for bookmark reminders. Every 5 minutes a schedule runs to check any reminders that need to be sent before now, limited to **300** reminders at a time. Any leftover reminders will be sent in the next run. This is to avoid having to deal with fickle sidekiq and reminders in the far-flung future, which would necessitate having a background job anyway to clean up any missing `enqueue_at` reminders.
* If a reminder is sent its `reminder_at` time is cleared and the `reminder_last_sent_at` time is filled in. Notifications are only user-level notifications for now.
* All JavaScript and frontend code related to displaying the bookmark reminder notification is contained here. The reminder functionality is now re-enabled in the bookmark modal as well.
* This PR also implements the "Remind me next time I am at my desktop" bookmark reminder functionality. When the user is on a mobile device they are able to select this option. When they choose this option we set a key in Redis saying they have a pending at desktop reminder. The next time they change devices we check if the new device is desktop, and if it is we send reminders using a DistributedMutex. There is also a job to ensure consistency of these reminders in Redis (in case Redis drops the ball) and the at desktop reminders expire after 20 days.
* Also in this PR is a fix to delete all Bookmarks for a user via `UserDestroyer`
There are three modifiers:
- serialize_topic_excerpts (boolean)
- csp_extensions (array of strings)
- svg_icons (array of strings)
When multiple themes are active, the values will be combined. The combination method varies based on the setting. CSP/SVG arrays will be combined. serialize_topic_excerpts will use `Enumerable#any`.
* DEV: Reserve webhook event types to be used in plugins
Based on feedback on the following PR's:
https://github.com/discourse/discourse-solved/pull/85https://github.com/discourse/discourse-assign/pull/61
This commit reserves ID's to be used for webhook event types to ensure
that some other webhook or plugin doesn't end up using the same ID.
* Fix broken test
I don't think this test has to test ALL event types to verify that this
feature is working. Now that we added some event types that plugins are
using this test was failing for missing fabricators that exist in the
respective plugins.
* remove loop and just test first record
### 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).
This syncs the value of the `reply_id` column into the `reply_post_id` column until all servers have been deployed and the post migrations ran.
Follow-up to ab07b945c2
### General Changes and Duplication
* We now consider a post `with_secure_media?` if it is in a read-restricted category.
* When uploading we now set an upload's secure status straight away.
* When uploading if `SiteSetting.secure_media` is enabled, we do not check to see if the upload already exists using the `sha1` digest of the upload. The `sha1` column of the upload is filled with a `SecureRandom.hex(20)` value which is the same length as `Upload::SHA1_LENGTH`. The `original_sha1` column is filled with the _real_ sha1 digest of the file.
* Whether an upload `should_be_secure?` is now determined by whether the `access_control_post` is `with_secure_media?` (if there is no access control post then we leave the secure status as is).
* When serializing the upload, we now cook the URL if the upload is secure. This is so it shows up correctly in the composer preview, because we set secure status on upload.
### Viewing Secure Media
* The secure-media-upload URL will take the post that the upload is attached to into account via `Guardian.can_see?` for access permissions
* If there is no `access_control_post` then we just deliver the media. This should be a rare occurrance and shouldn't cause issues as the `access_control_post` is set when `link_post_uploads` is called via `CookedPostProcessor`
### Removed
We no longer do any of these because we do not reuse uploads by sha1 if secure media is enabled.
* We no longer have a way to prevent cross-posting of a secure upload from a private context to a public context.
* We no longer have to set `secure: false` for uploads when uploading for a theme component.
API keys are now only visible when first created. After that, only the first four characters are stored in the database for identification, along with an sha256 hash of the full key. This makes key usage easier to audit, and ensures attackers would not have access to the live site in the event of a database leak.
This makes the merge lower risk, because we have some time to revert if needed. Once the change is confirmed to be working, we will add a second commit to drop the `key` column.
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.
We like to stay as close as possible to latest with rubocop cause the cops
get better.
This update required some code changes, specifically the default is to avoid
explicit returns where implicit is done
Also this renames a few rules
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.
* Add timezone to user_options table
* Also migrate existing timezone values from UserCustomField,
which is where the discourse-calendar plugin is storing them
* Allow user to change their core timezone from Profile
* Auto guess & set timezone on login & invite accept & signup
* Serialize user_options.timezone for group members. this is so discourse-group-timezones can access the core user timezone, as it is being removed in discourse-calendar.
* Annotate user_option with timezone
* Validate timezone values
This PR introduces a new secure media setting. When enabled, it prevent unathorized access to media uploads (files of type image, video and audio). When the `login_required` setting is enabled, then all media uploads will be protected from unauthorized (anonymous) access. When `login_required`is disabled, only media in private messages will be protected from unauthorized access.
A few notes:
- the `prevent_anons_from_downloading_files` setting no longer applies to audio and video uploads
- the `secure_media` setting can only be enabled if S3 uploads are already enabled and configured
- upload records have a new column, `secure`, which is a boolean `true/false` of the upload's secure status
- when creating a public post with an upload that has already been uploaded and is marked as secure, the post creator will raise an error
- when enabling or disabling the setting on a site with existing uploads, the rake task `uploads:ensure_correct_acl` should be used to update all uploads' secure status and their ACL on S3
* Fix user title logic when badge name customized
* Fix an issue where a user's title was not considered a badge granted title when the user used a badge for their title and the badge name was customized. this affected the effectiveness of revoke_ungranted_titles! which only operates on badge_granted_titles.
* When a user's title is set now it is considered a badge_granted_title if the badge name OR the badge custom name from TranslationOverride is the same as the title
* When a user's badge is revoked we now also revoke their title if the user's title matches the badge name OR the badge custom name from TranslationOverride
* Add a user history log when the title is revoked to remove confusion about why titles are revoked
* Add granted_title_badge_id to user_profile, now when we set badge_granted_title on a user profile when updating a user's title based on a badge, we also remember which badge matched the title
* When badge name (or custom text) changes update titles of users in a background job
* When the name of a badge changes, or in the case of system badges when their custom translation text changes, then we need to update the title of all corresponding users who have a badge_granted_title and matching granted_title_badge_id. In the case of system badges we need to first get the proper badge ID based on the translation key e.g. badges.regular.name
* Add migration to backfill all granted_title_badge_ids for both normal badge name titles and titles using custom badge text.
Previously our index was non unique, causing situations where a user could
have multiple drafts stored in the table for the same exact entity.
This does not properly reflect reality and needed to change as in certain
cases duplicate drafts could be created causing internal data inconsistency
- Allow revoking keys without deleting them
- Auto-revoke keys after a period of no use (default 6 months)
- Allow multiple keys per user
- Allow attaching a description to each key, for easier auditing
- Log changes to keys in the staff action log
- Move all key management to one place, and improve the UI
This ensures we can very quickly figure out which topics are banners if
a banner is set.
Previously you would have to scan an entire table to find banners
In a category's settings, the Tags tab has two new fields to
specify the number of tags that must be added to a topic
from a tag group. When creating a new topic, an error will be
shown to the user if the requirement isn't met.
This is a major change to draft internals. Previously there were quite a
few cases where the draft system would say "draft saved", when in fact
we just skipped saving.
This commit ensures the draft system deals with draft ownership handover in
a predictable way.
For example:
- Window 1 editing draft
- Window 2 editing same draft at the same time
Previously we would allow window 1 and 2 to just fight on the same draft
each window overwriting the same draft over an over.
This commit introduces an ownership concept where either window 1 or 2 win
and user is prompted on the loser window to reload screen to correct the issue
This also corrects edge cases where a user could have multiple browser windows
open and posts in 1 window, later to post in the second window. Previously
drafts would break in the second window, this corrects it.
Certain DBs have duplicates already, if we want to ensure uniqueness here
we need to decide first how to clean up existing data and confirm all the
plugins expect this.
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.
Slugs can be the empty string, but the added index didn't account for
that. This commit changes the migration, stopping it from being unique
so that it can be applied everywhere and adds another migration that
recreates the index properly.
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).
* 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
If a user amended edit_time_limit keep the behavior as is, instead of introducing a potentially tighter time for tl2 edit time than what they had set in the past.
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.
* 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
* 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
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.
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.
Temporarily recreate already dropped functions in the discourse_functions schema in order to allow restoring of backups which still reference dropped functions.
* 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'
* DEV: group_list site settings should store IDs instead of group names
* Ship site setting to know when we should migrate group_list settings
* Migrate existing group_list site settings
* Bump migration timestamp and don't set null when migrating is not possible.
DEV: deprecate `invite.via_email` in favor of `invite.emailed_status`
This commit adds a new column `emailed_status` in `invites` table for
tracking email sending status.
0 - not required
1 - pending
2 - bulk pending
3 - sending
4 - sent
For normal email invites, invite record is created with emailed_status
set to 'pending'.
When bulk invites are sent invite record is created with emailed_status
set to 'bulk pending'.
For invites that generates link, invite record is created with
emailed_status set to 'not required'.
When invite email is in queue emailed_status is updated to 'sending'
Once the email is sent via `InviteEmail` job the invite emailed_status
is updated to 'sent'.
- adds a migration renaming FA4 icon names in badges
- allows all icons to be used in badges (previously was limited to icons prefixed with fa-)
- renames remaining FA 4.7 icons equivalents
In order for this to work the Backuper stores a couple of site settings
in the new backup_metadata table, because the old setting values might
not be available on restore anymore.
Groups can now be marked as visible to "logged on users". All automatic groups (except `everyone`) are now visible to "logged on users", previously they were marked as public but suppressed in the group page for non-staff.
This allows you to temporarily disable components without having to remove them from a theme.
This feature is very handy when doing quick fix engineering.
Adds a second factor landing page that centralizes a user's second factor configuration.
This contains both TOTP and Backup, and also allows multiple TOTP tokens to be registered and organized by a name. Access to this page is authenticated via password, and cached for 30 minutes via a secure session.
* Remove unused method
* Prefabricate user in category_user_spec.rb
* FIX: Remove notification_level from category_users unique indexes
* FIX: CategoryUser#batch_set wasn't updating pre-existing records
* Improve tests for CategoryUser#batch_set
* FIX: changed was being reported incorrectly
* DEV: Rewrote query to do a bulk insert
* DEV: remove unnecessary parentheses
You can now add javascript files under `/javascripts/*` in a theme, and they will be loaded as if they were included in core, or a plugin. If you give something the same name as a core/plugin file, it will be overridden. Support file extensions are `.js.es6`, `.hbs` and `.raw.hbs`.
This feature allows end users to "defer" topics by marking them unread
The functionality is default disabled. This also introduces the new site
setting default_other_enable_defer: to enable this by default on new user
accounts.
Previously we used custom fields to denote a user was anonymous, this was
risky in that custom fields are prone to race conditions and are not
properly dedicated, missing constraints and so on.
The new table `anonymous_users` is properly protected. There is only one
possible shadow account per user, which is enforced using a constraint.
Every anonymous user will have a unique row in the new table.
The migration for the ToS signup field happend in 2014. Everyone who hasn't updated yet needs to live with the English text "Terms of Service". There's no need to keep these unused translations forever.
User.publish_notifications_state is called every time a notification is
created, this can become a very critical code path.
On some heavy notification related sites this can be a major CPU user on PG
This index makes it much cheaper to publish notification state, cause a
simple index lookup does the trick.
This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.
Test suite passes now, but there may be some stuff left, so we will run
a few sites on a branch prior to merging
This is a feature that used to be present in discourse-assign but is
much easier to implement in core. It also allows a topic to be assigned
without it claiming for review and vice versa and allows it to work with
category group reviewers.
This change shows a notification number besides the flag icon in the
post menu if there is reviewable content associated with the post.
Additionally, if there is pending stuff to review, the icon has a red
background.
We have also removed the list of links below a post with the flag
status. A reviewer is meant to click the number beside the flag icon to
view the flags. As a consequence of losing those links, we've removed
the ability to undo or ignore flags below a post.
`Upload#url` is more likely and can change from time to time. When it
does changes, we don't want to have to look through multiple tables to
ensure that the URLs are all up to date. Instead, we simply associate
uploads properly to `UserProfile` so that it does not have to replicate
the URLs in the table.
This is a regression as a result of 7896c74c2b. Most instances would have ran the migrations and some might have run this migration with the incorrect query. Impact of this is small for now but I'm fixing this for correctness purposes.
This change automatically resizes icons for various purposes. Admins can now upload `logo` and `logo_small`, and everything else will be auto-generated. Specific icons can still be uploaded separately if required.
## Core
- Adds an SiteIconManager module which manages automatic resizing and fallback
- Icons are looked up in the OptimizedImage table at runtime, and then cached in Redis. If the resized version is missing for some reason, then most icons will fall back to the original files. Some icons (e.g. PWA Manifest) will return `nil` (because an incorrectly sized icon is worse than a missing icon).
- `SiteSetting.site_large_icon_url` will return the optimized version, including any fallback. `SiteSetting.large_icon` continues to return the upload object. This means that (almost) no changes are required in core/plugins to support this new system.
- Icons are resized whenever a relevant site setting is changed, and during post-deploy migrations
## Wizard
- Allows `requiresRefresh` wizard steps to reload data via AJAX instead of a full page reload
- Add placeholders to the **icons** step of the wizard, which automatically update from the "Square Logo"
- Various copy updates to support the changes
- Remove the "upload-time" resizing for `large_icon`. This is no longer required.
## Site Settings UX
- Move logo/icon settings under a new "Branding" tab
- Various copy changes to support the changes
- Adds placeholder support to the `image-uploader` component
- Automatically reloads site settings after saving. This allows setting placeholders to change based on changes to other settings
- Upload site settings will be assigned a placeholder if SiteIconManager `responds_to?` an icon of the same name
## Dashboard Warnings
- Remove PWA icon and PWA title warnings. Both are now handled automatically.
## Bonus
- Updated the sketch logos to use @awesomerobot's new high-res designs
