Previously we were calling `EXPIRE` every time we incremented a given key. Instead, we can call EXPIRE once when the key is first populated. A LUA script is used to make this as efficient as possible.
Consumers of this Concern use daily keys. Since we're now calling EXPIRE only at the beginning of the day, rather than throughout the day, the expire time has been increased from 3 to 4 days.
Whenever we got a bounced email in the Email::Receiver we
previously would just set bounced: true on the EmailLog and
discard the status/diagnostic code. This commit changes this
flow to store the bounce error code (defined in the RFC at
https://www.iana.org/assignments/smtp-enhanced-status-codes/smtp-enhanced-status-codes.xhtml)
not just in the Email::Receiver, but also via webhook events
from other mail services and from SNS.
This commit does not surface the bounce error in the UI,
we can do that later if necessary.
There is a couple of layers of caching for theme JavaScript in Discourse:
The first layer is the `javascript_caches` table in the database. When a theme
with JavaScript files is installed, Discourse stores each one of the JavaScript
files in the `theme_fields` table, and then concatenates the files, compiles
them, computes a SHA1 digest of the compiled JavaScript and store the results
along with the SHA1 digest in the `javascript_caches` table.
Now when a request comes in, we need to render `<script>` tags for the
activated theme(s) of the site. To do this, we retrieve the `javascript_caches`
records of the activated themes and generate a `<script>` tag for each record.
The `src` attribute of these tags is a path to the `/theme-javascripts/:digest`
route which simply responds with the compiled JavaScript that has the requested
digest.
The second layer is a distributed cache whose purpose is to make rendering
`<script>` a lot more efficient. Without this cache, we'd have to query the
`javascript_caches` table to retrieve the SHA1 digests for every single
request. So we use this cache to store the `<script>` tags themselves so that
we only have to retrieve the `javascript_caches` records of the activated
themes for the first request and future requests simply get the cached
`<script>` tags.
What this commit does it ensures that the SHA1 digest in the
`javascript_caches` table stay the same across compilations by adding an order
by id clause to the query that loads the `theme_fields` records. Currently, we
specify no order when retrieving the `theme_fields` records so the order in
which they're retrieved can change across compilations and therefore cause the
SHA1 to change even though the individual records have not changed at all.
An inconsistent SHA1 digest across compilations can cause the database cache
and the distributed cache to have different digests and that causes the
JavaScript to fail to load (and if the theme heavily customizes the site, it
gives the impression that the site is broken) until the cache is cleared.
This can happen in busy sites when 2 concurrent requests recompile the
JavaScript files of a theme at the same time (this can happen when deploying a
new Discourse version) and request A updates the database cache after request B
did, and request B updates the distributed cache after request A did.

- Update UI to improve contrast
- Make it clear that the message is only shown to administrators
- Add theme name and id to the console output
- Parse the error backtrace to identify the theme-id for post-decoration errors
- Improve console output to include the theme name / URL
- Add `?safe_mode=no_custom` to the admin panel link, so that it will work even if the theme is causing the site to break
In 8e5b945b0f, we reverted the commit but
at the same time resulted in Theme::BASE_COMPILER_VERSION going
backwards which caused problems with themes caching.
This commit bumps the version to clear all the caches.
Follow-up to 8e5b945b0f
Breakdown of fixes in this commit:
* `UserStat#topic_count` was not updated when visibility of
the topic changed.
* `UserStat#post_count` was not updated when post was hidden or
unhidden.
* `TopicConverter` was only incrementing or decrementing the counts by 1
even if a user has multiple posts in the topic.
* The commit turns off the verbose logging by default as it is just
noise to normal users who are not debugging this problem.

This commits adds a new advance_draft to PostCreator that controls if
the draft sequence will be advanced or not. If the draft sequence is
advanced then the old drafts will be cleared. This used to happen for
posts created by plugins or through the API and cleared user drafts
by mistake.
* FEATURE: Add external_id to topics
This commit allows for topics to be created and fetched by an
external_id. These changes are API only for now as there aren't any
front changes.
* add annotations
* add external_id to this spec
* Several PR feedback changes
- Add guardian to find topic
- 403 is returned for not found as well now
- add `include_external_id?`
- external_id is now case insensitive
- added test for posts_controller
- added test for topic creator
- created constant for max length
- check that it redirects to the correct path
- restrain external id in routes file
* remove puts
* fix tests
* only check for external_id in webhook if exists
* Update index to exclude external_id if null
* annotate
* Update app/controllers/topics_controller.rb
We need to check whether the topic is present first before passing it to the guardian.

This commit allows group SMTP emails to be sent with a
different from email address that has been set up as an
alias in the email provider. Emails from the alias will
be grouped correctly using Message-IDs in the mail client,
and replies to the alias go into the correct group inbox.
Ensures that `UserStat#post_count` and `UserStat#topic_count` does not
go below 0. When it does like it did now, we tend to have bugs in our
code since we're usually coding with the assumption that the count isn't
negative.
In order to support the constraints, our post and topic fabricators in
tests will now automatically increment the count for the respective
user's `UserStat` as well. We have to do this because our fabricators
bypasss `PostCreator` which holds the responsibility of updating `UserStat#post_count` and
`UserStat#topic_count`.
Job arguments go via JSON, and so DateTime objects will appear as strings in the Job's `#execute` method. The latest version of Sidekiq has started warning about this to reduce developer confusion.
Non-staff users are not allowed to see whisper so this change prevents
non-staff user from seeing a like count that does not make sense to
them. In the future, we might consider adding another like count column
for staff user.

When the record is not saved, we should display a proper message.
One potential reason can be plugins for example discourse-calendar is specifying that only first post can contain event
Sometimes plugins need to have additional data or options available
when rendering custom markdown features/rules that are not available
on the default opts.discourse object. These additional options should
be namespaced to the plugin adding them.
```
Site.markdown_additional_options["chat"] = { limited_pretty_text_markdown_rules: [] }
```
These are passed down to markdown rules on opts.discourse.additionalOptions.
The main motivation for adding this is the chat plugin, which currently stores
chat_pretty_text_features and chat_pretty_text_markdown_rules on
the Site object via additions to the serializer, and the Site object is
not accessible to import via markdown rules (either through
Site.current() or through container.lookup). So, to have this working
for both front + backend code, we need to attach these additional options
from the Site object onto the markdown options object.
We initialize models as part of the warmup process in production, so this was being logged on every boot. We only want to log if a plugin is actually using the model, so after_save is a safer bet.

Probably best to lookup the "everyone" group_id instead of hard-coding
it to `0`. Also now its more clear what this `0` means.
Running `update_from_remote` and `save!` cause a number of side-effects, including instructing all clients to reload CSS files. If there are no changes, then this is wasteful, and can even cause a 'flicker' effect on clients as they reload CSS.
This commit checks if any updates are available before triggering `update_from_remote` / `save!`. This should be much faster, and stop the 'flickering' UX from happening on every themes:update run.
It also improves the output of the command to include the from/to commit hashes, which may be useful for debugging issues. For example:
```
Checking 'Alien Night | A Dark Discourse Theme' for 'default'... already up to date
Checking 'Star Wars' for 'default'... updating from d8a170dd to 66b9756f
Checking 'Media Overlay' for 'default'... already up to date
```
If a model class calls preload_custom_fields twice then
we have to clear this otherwise the fields are cached inside the
already existing proxy and no new ones are added, so when we check
for custom_fields[KEY] an error is likely to occur
This commit makes a more specific N1NotPreLoadedError from
StandardError to raise when a custom field is loaded before
being preloaded, so it is easier to test that this does
not happen from plugins. Also adds the name of the class
trying to load the custom field to the error message.
In the unlikely, but possible, scenario where a user has no email_tokens, and has an invite record for their email address, login would fail. This commit fixes the `Invite` `user_doesnt_already_exist` validation so that it only applies to new invites, or when changing the email address.
This regressed in d8fe0f4199 (based on `git bisect`)
* FIX: Tag watching for everyone tag groups
Tags in tag groups that have permissions set to everyone were not able
to be saved correctly. A user on their preferences page would mark the
tags that they wanted to save, but the watched_tags in the response
would be empty. This did not apply to admins, just regular users. Even
though the watched tags were being saved in the db, the user serializer
response was filtering them out. When a user refreshed their preferences
pages it would show zero watched tags.
This appears to be a regression introduced by:
0f598ca51e
The issue that needed to be fixed is that we don't track the "everyone"
group (which has an id of 0) in the group_users table. This is because
everyone has access to it, so why fill a row for every single user, that
would be a lot. The fix was to update the query to include tag groups
that had permissions set to the "everyone" group (group_id 0).
I also added another check to the existing spec for updating
watched tags for tags that aren't in a tag group so that it checks the
response body. I then added a new spec which updates watched tags for
tags in a tag group which has permissions set to everyone.
* Resolve failing tests
Improve SQL query syntax for including the "everyone" group with the id
of 0.
This commit also fixes a few failing tests that were introduced. It
turns out that the Fabrication of the Tag Group Permissions was faulty.
What happens when creating the tag groups without any permissions is
that it sets the permission to "everyone". If we then follow up with
fabricating a tag group permission on the tag group instead of having a
single permission it will have 2 (everyone + the group specified)! We
don't want this. To fix it I removed the fabrication of tag group
permissions and just set the permissions directly when creating the tag
group.
* Use response.parsed_body instead of JSON.parse
* FIX: Mark invites flash messages as HTML safe.
This change should be safe as all user inputs included in the errors are sanitized before sending it back to the client.
Context: https://meta.discourse.org/t/html-tags-are-explicit-after-latest-update/214220
* If somebody adds a new error message that includes user input and doesn't sanitize it, using html-safe suddenly becomes unsafe again. As an extra layer of protection, we make the client sanitize the error message received from the backend.
* Escape user input instead of sanitizing
The `plugin:pull_compatible_all` task is intended to take incompatible plugins and downgrade them to an earlier version. Problem is, when running the rake task in development/production environments, the plugins have already been activated. If an incompatible plugin raises an error in `plugin.rb` then the rake task will be unable to start.
This commit centralises our LOAD_PLUGINS detection, adds support for LOAD_PLUGINS=0 in dev/prod, and adds a warning to `plugin:pull_compatible_all` if it's run with plugins enabled.
An admin could search for all screened ip addresses in a block by
using wildcards. 192.168.* returned all IPs in range 192.168.0.0/16.
This feature allows admins to search for a single IP address in all
screened IP blocks. 192.168.0.1 returns all IP blocks that match it,
for example 192.168.0.0/16.
* FEATURE: Remove roll up button for screened IPs
* FIX: Match more specific screened IP address first
Having to load `ip_addr` is confusing especially when that file exists
to monkey patch Ruby's `IpAddr` class. Moving it to our freedom patches
folder which is automatically loaded on initialization.
This is a partial revert of 099b679fc5.
`Bookmark#topic_id` and `Bookmark#reminder_type` was dropped in
b22450c7a8 so we need to continue ignoring
the dropped columns so as to ensure a seamless deploy. Otherwise,
ActiveRecord's schema cache will still contain references to
`Bookmark#topic_id` when the column is dropped in a post migration.
It is too close to release of 2.8 for incomplete
feature shenanigans. Ignores and drops the columns and drops
the trigger/function introduced in
e21c640a3c.
Will pick this feature back up post-release.
We are planning on attaching bookmarks to more and
more other models, so it makes sense to make a polymorphic
relationship to handle this. This commit adds the new
columns and backfills them in the bookmark table, and
makes sure that any new bookmark changes fill in the columns
via DB triggers.
This way we can gradually change the frontend and backend
to use these new columns, and eventually delete the
old post_id and for_topic columns in `bookmarks`.
* File.exists? is deprecated and removed in Ruby 3.2 in favor of
File.exist?
* Dir.exists? is deprecated and removed in Ruby 3.2 in favor of
Dir.exist?
The rake task deleted here was added back in Feb 2020
when bookmarks were first converted from PostAction
records, it is no longer needed. The ignored columns
were removed in ed83d7573e.
This commit adds a check that runs regularly as per
2d68e5d942 which tests the
credentials of groups with SMTP or IMAP enabled. If any issues
are found with those credentials a high priority problem is added to the
admin dashboard.
This commit also formats the admin dashboard differently if
there are high priority problems, bringing them to the top of
the list and highlighting them.
The problem will be cleared if the issue is fixed before the next
problem check, or if the group's settings are updated with a valid
credential.
The `fancy_title` column in the `topics` table currently has a constraint that limits the column to 400 characters. We need to remove that constraint because it causes some automatic topics/PMs from the system to fail when using Discourse in locales that need more than 400 characters to the translate the content of those automatic messages.
Internal ticket: t58030.
This commit introduces scheduled problem checks for the admin dashboard, which are long running or otherwise cumbersome problem checks that will be run every 10 minutes rather than every time the dashboard is loaded. If these scheduled checks add a problem, the problem will remain until it is cleared or until the scheduled job runs again.
An example of a check that should be scheduled is validating credentials against an external provider.
This commit also introduces the concept of a `priority` to the problems generated by `AdminDashboardData` and the scheduled checks. This is `low` by default, and can be set to `high`, but this commit does not change any part of the UI with this information, only adds a CSS class.
I will be making a follow up PR to check group SMTP credentials.
Some time ago, we made this fix to external authentication – https://github.com/discourse/discourse/pull/13706. We didn't address Discourse Connect (https://meta.discourse.org/t/discourseconnect-official-single-sign-on-for-discourse-sso/13045) at that moment, so I wanted to fix it for Discourse Connect as well.
Turned out though that Discourse Connect doesn't contain this problem and already handles staged users correctly. This PR adds tests that confirm it. Also, I've extracted two functions in Discourse Connect implementation along the way and decided to merge this refactoring too (the refactoring is supported with tests).
This commit introduces a new site setting "google_oauth2_hd_groups". If enabled, group information will be fetched from Google during authentication, and stored in the Discourse database. These 'associated groups' can be connected to a Discourse group via the "Membership" tab of the group preferences UI.
The majority of the implementation is generic, so we will be able to add support to more authentication methods in the near future.

The `ReviewableScore` model was defining class methods on `self.class`
from a singleton context so instead of defining methods on
`ReviewableScore` it was defining them on `Class`, so basically on every
existing class.
This patch resolves this issue. Using `enum` from `ActiveRecord` in the
future will avoid this kind of problems.
Related to: 20f736aa11.
`auto_update` is true by default at the database level, but it doesn't make sense for `auto_update` to be true on themes that are not imported from a Git repository.
* REFACTOR: Improve support for consolidating notifications.
Before this commit, we didn't have a single way of consolidating notifications. For notifications like group summaries, we manually removed old ones before creating a new one. On the other hand, we used an after_create callback for likes and group membership requests, which caused unnecessary work, as we need to delete the record we created to replace it with a consolidated one.
We now have all the consolidation rules centralized in a single place: the consolidation planner class. Other parts of the app looking to create a consolidable notification can do so by calling Notification#consolidate_or_save!, instead of the default Notification#create! method.
Finally, we added two more rules: one for re-using existing group summaries and another for deleting duplicated dashboard problems PMs notifications when the user is tracking the moderator's inbox. Setting the threshold to one forces the planner to apply this rule every time.
I plan to add plugin support for adding custom rules in another PR to keep this one relatively small.
* DEV: Introduces a plugin API for consolidating notifications.
This commit removes the `Notification#filter_by_consolidation_data` scope since plugins could have to define their criteria. The Plan class now receives two blocks, one to query for an already consolidated notification, which we'll try to update, and another to query for existing ones to consolidate.
It also receives a consolidation window, which accepts an ActiveSupport::Duration object, and filter notifications created since that value.
Currently when a user creates posts that are moderated (for whatever
reason), a popup is displayed saying the post needs approval and the
total number of the user’s pending posts. But then this piece of
information is kind of lost and there is nowhere for the user to know
what are their pending posts or how many there are.
This patch solves this issue by adding a new “Pending” section to the
user’s activity page when there are some pending posts to display. When
there are none, then the “Pending” section isn’t displayed at all.
Skipping methods we don't use gives us mem/perf gains (minuscule but still), but more importantly fixes warnings about `Poll#open` (created by `enum :status`) conflicting with some internal AR method. 😃
`pending`, `approved`, `rejected`, `ignored`, and `deleted` scope method were accessible on all model classes… 😂
Fixes `Creating scope :pending. Overwriting existing method DiscoursePostEvent::EventDate.pending.` warnings.
This commit adds token_hash and scopes columns to email_tokens table.
token_hash is a replacement for the token column to avoid storing email
tokens in plaintext as it can pose a security risk. The new scope column
ensures that email tokens cannot be used to perform a different action
than the one intended.
To sum up, this commit:
* Adds token_hash and scope to email_tokens
* Reuses code that schedules critical_user_email
* Refactors EmailToken.confirm and EmailToken.atomic_confirm methods
* Periodically cleans old, unconfirmed or expired email tokens
When this setting is turned on, it will check that normalized emails
are unique. Normalized emails are emails without any dots or plus
aliases.
This setting can be used to block use of aliases of the same email
address.
Use @here to mention all users that were allowed to topic directly or
through group, who liked topics or read the topic. Only first 10 users
will be notified.
In b8c8909a9d, we introduced a regression
where users may have had their `UserStat.first_unread_pm_at` set
incorrectly. This commit introduces a migration to reset `UserStat.first_unread_pm_at` back to
`User#created_at`.
Follow-up to b8c8909a9d.
The code that checked this permission was duplicated everytime a new
settings of this type was added. This commit changes the behavior of
some functionality because some feature checks were bypassed for staff
members.
Similar to site settings, adds support for `refresh` option to theme settings.
```yaml
super_feature_enabled:
type: bool
default: false
refresh: true
```
We are pushing /notification-alert/#{user_id} and /notification/#{user_id}
messages to MessageBus from both PostAlerter and User#publish_notification_state.
This can cause memory issues on large sites with many users. This commit
stems the bleeding by only sending these alert messages if the user
in question has been seen in the last 30 days, which eliminates a large
chunk of users on some sites.
The inefficiency here is that we were previously fetching all the
records from `TopicAllowedUser` before filtering against a limited subset of
users based on `User#last_seen_at`.
Previously, incorrect reply counts are displayed in the "top categories" section of the user summary page since we included the `moderator_action` and `small_action` post types.

Currently, Discourse rate limits all incoming requests by the IP address they
originate from regardless of the user making the request. This can be
frustrating if there are multiple users using Discourse simultaneously while
sharing the same IP address (e.g. employees in an office).
This commit implements a new feature to make Discourse apply rate limits by
user id rather than IP address for users at or higher than the configured trust
level (1 is the default).
For example, let's say a Discourse instance is configured to allow 200 requests
per minute per IP address, and we have 10 users at trust level 4 using
Discourse simultaneously from the same IP address. Before this feature, the 10
users could only make a total of 200 requests per minute before they got rate
limited. But with the new feature, each user is allowed to make 200 requests
per minute because the rate limits are applied on user id rather than the IP
address.
The minimum trust level for applying user-id-based rate limits can be
configured by the `skip_per_ip_rate_limit_trust_level` global setting. The
default is 1, but it can be changed by either adding the
`DISCOURSE_SKIP_PER_IP_RATE_LIMIT_TRUST_LEVEL` environment variable with the
desired value to your `app.yml`, or changing the setting's value in the
`discourse.conf` file.
Requests made with API keys are still rate limited by IP address and the
relevant global settings that control API keys rate limits.
Before this commit, Discourse's auth cookie (`_t`) was simply a 32 characters
string that Discourse used to lookup the current user from the database and the
cookie contained no additional information about the user. However, we had to
change the cookie content in this commit so we could identify the user from the
cookie without making a database query before the rate limits logic and avoid
introducing a bottleneck on busy sites.
Besides the 32 characters auth token, the cookie now includes the user id,
trust level and the cookie's generation date, and we encrypt/sign the cookie to
prevent tampering.
Internal ticket number: t54739.
When there are multiple groups on a topic, we were selecting
the first from the topic allowed groups to act as the sender
email address when sending group SMTP replies via PostAlerter.
However, this was not ordered, and since there is no created_at
column on TopicAllowedGroup we cannot order this nicely, which
caused just a random group to be used (based on whatever postgres
decided it felt like that morning).
This commit changes the group used for SMTP sending to be the
group using the email_username of the to address of the first
incoming email for the topic, if there are more than one allowed
groups on the topic. Otherwise it just uses the only SMTP enabled
group.
Previously, suppressed category topics are included in the digest emails if the user visited that topic before and the `TopicUser` record is created with any notification level except 'muted'.
* FIX: allowed_theme_ids should not be persisted in GlobalSettings
It was observed that the memoized value of `GlobalSetting.allowed_theme_ids` would be persisted across requests, which could lead to unpredictable/undesired behaviours in a multisite environment.
This change moves that logic out of GlobalSettings so that the returned theme IDs are correct for the current site.
Uses get_set_cache, which ultimately uses DistributedCache, which will take care of multisite issues for us.
* DEV: Sanitize HTML admin inputs
This PR adds on-save HTML sanitization for:
Client site settings
translation overrides
badges descriptions
user fields descriptions
I used Rails's SafeListSanitizer, which [accepts the following HTML tags and attributes](018cf54073/lib/rails/html/sanitizer.rb (L108))
* Make sure that the sanitization logic doesn't corrupt settings with special characters
This PR doesn't change any behavior, but just removes code that wasn't in use. This is a pretty dangerous place to change, since it gets called during user's registration. At the same time the refactoring is very straightforward, it's clear that this code wasn't doing any work (it still needs to be double-checked during review though). Also, the test coverage of UserNameSuggester is good.
* PERF: Remove JOIN on categories for PM search
JOIN on categories is not needed when searchin in private messages as
PMs are not categorized.
* DEV: Use == for string comparison
* PERF: Optimize query for allowed topic groups
There was a query that checked for all topics a user or their groups
were allowed to see. This used UNION between topic_allowed_users and
topic_allowed_groups which was very inefficient. That was replaced with
a OR condition that checks in either tables more efficiently.
When inviting a group to a topic, there may be members of
the group already in the topic as topic allowed users. These
can be safely removed from the topic, because they are implicitly
allowed in the topic based on their group membership.
Also, this prevents issues with group SMTP emails, which rely
on the topic_allowed_users of the topic to send to and cc's
for emails, and if there are members of the group as topic_allowed_users
then that complicates things and causes odd behaviour.
We also ensure that the OP of the topic is not removed from
the topic_allowed_users when a group they belong to is added,
as it will make it harder to add them back later.
The `generate`, `rotate` and `suspicious` auth token logs are now always logged regardless of the `verbose_auth_token_logging` setting because we rely no these to detect suspicious logins.
This is a follow-up to https://github.com/discourse/discourse/pull/14541. This adds a hidden setting for restoring the old behavior for those users who rely on it. We'll likely deprecate this setting at some point in the future.
Sometimes administrators want to permanently delete posts and topics
from the database. To make sure that this is done for a good reasons,
administrators can do this only after one minute has passed since the
post was deleted or immediately if another administrator does it.
We don't want to be using emails as source for username and name suggestions in cases when it's possible that a user have no chance to intervene and correct a suggested username. It risks exposing email addresses.
Previosuly, quotes from original topics are rendered incorrectly since the moved posts are not rebaked.

Ruby 2.7 or earlier `+contents` returns self.dup
when `frozen_string_literal: true`. However, Ruby 3.0 returns self

This commit uses self.dup to return duplicated string regardless Ruby
versions.

* FEATURE: Return subcategories on categories endpoint
When using the API subcategories will now be returned nested inside of
each category response under the `subcategory_list` param. We already
return all the subcategory ids under the `subcategory_ids` param, but
you then would have to make multiple separate API calls to fetch each of
those subcategories. This way you can get **ALL** of the categories
along with their subcategories in a single API response.
The UI will not be affected by this change because you need to pass in
the `include_subcategories=true` param in order for subcategories to be
returned.
In a follow up PR I'll add the API scoping for fetching categories so
that a readonly API key can be used for the `/categories.json` endpoint. This
endpoint should be used instead of the `/site.json` endpoint for
fetching a sites categories and subcategories.
* Update PR based on feedback
- Have spec check for specific subcategory
- Move comparison check out of loop
- Only populate subcategory list if option present
- Remove empty array initialization
- Update api spec to allow null response
* More PR updates based on feedback
- Use a category serializer for the subcategory_list
- Don't include the subcategory_list param if empty
- For the spec check for the subcategory by id
- Fix spec to account for param not present when empty
FinalDestination now supports the `follow_canonical` option, which will perform an initial GET request, parse the canonical link if present, and perform a HEAD request to it.
We use this mode during embeds to avoid treating URLs with different query parameters as different topics.
It was possible to see notifications of other users using routes:
- notifications/responses
- notifications/likes-received
- notifications/mentions
- notifications/edits
We weren't showing anything private (like notifications about private messages), only things that're publicly available in other places. But anyway, it feels strange that it's possible to look at notifications of someone else. Additionally, there is a risk that we can unintentionally leak something on these pages in the future.

* PERF: Improve database query perf when loading topics for a category.
Instead of left joining the `topics` table against `categories` by filtering with `categories.id`,
we can improve the query plan by filtering against `topics.category_id`
first before joining which helps to reduce the number of rows in the
topics table that has to be joined against the other tables and also
make better use of our existing index.
The following is a before and after of the query plan for a category
with many subcategories.
Before:

* PERF: Optimize index on topics bumped_at.
Replace `index_topics_on_bumped_at` index with a partial index on `Topic#bumped_at` filtered by archetype since there is already another index that covers private topics.
* DEV: use active record `save!` instead of mini sql.
The "save" method will trigger the before_save callback "match_primary_group_changes" for User model. Else `flair_group_id` won't be removed from the user.
* check whether the method `match_primary_group_changes` called or not.
Allows creating a bookmark with the `for_topic` flag introduced in d1d2298a4c set to true. This happens when clicking on the Bookmark button in the topic footer when no other posts are bookmarked. In a later PR, when clicking on these topic-level bookmarks the user will be taken to the last unread post in the topic, not the OP. Only the OP can have a topic level bookmark, and users can also make a post-level bookmark on the OP of the topic.
I had to do some pretty heavy refactors because most of the bookmark code in the JS topics controller was centred around instances of Post JS models, but the topic level bookmark is not centred around a post. Some refactors were just for readability as well.
Also removes some missed reminderType code from the purge in 41e19adb0d
After deleting a category, we should soft-delete the category definition topic instead of hard deleting it. Else it causes issues while doing the user merge action if the source user has an orphan post that belongs to the deleted topic.
We don't actually use the reminder_type for bookmarks anywhere;
we are just storing it. It has no bearing on the UI. It used
to be relevant with the at_desktop bookmark reminders (see
fa572d3a7a)
This commit marks the column as readonly, ignores it, and removes
the index, and it will be dropped in a later PR. Some plugins
are relying on reminder_type partially so some stubs have been
left in place to avoid errors.
This new column will be used to indicate that a bookmark
is at the topic level. The first post of a topic can be
bookmarked twice after this change -- with for_topic set
to true and with for_topic set to false.
A later PR will use this column for logic to bookmark the
topic, and then topic-level bookmark links will take you
to the last unread post in the topic.

We don't need no stinkin' denormalization! This commit ignores
the topic_id column on bookmarks, to be deleted at a later date.
We don't really need this column and it's better to rely on the
post.topic_id as the canonical topic_id for bookmarks, then we
don't need to remember to update both columns if the bookmarked
post moves to another topic.
The previous excerpt was a simple truncated raw message. Starting with
this commit, the raw content of the draft is cooked and an excerpt is
extracted from it. The logic for extracting the excerpt mimics the the
`ExcerptParser` class, but does not implement all functionality, being
a much simpler implementation.
The two draft controllers have been merged into one and the /draft.json
route has been changed to /drafts.json to be consistent with the other
route names.
This is necessary to allow for large file uploads via
the direct S3 upload mechanism, as we convert the external
file to an Upload record via ExternalUploadManager once
it is complete.
This will allow for files larger than 2,147,483,647 bytes (2.14GB)
to be referenced in the uploads table.
This is a table locking migration, but since it is not as highly
trafficked as posts, topics, or users, the disruption should be minimal.
When a user archives a personal message, they are redirected back to the
inbox and will refresh the list of the topics for the given filter.
Publishing an event to the user results in an incorrect incoming message
because the list of topics has already been refreshed.
This does mean that if a user has two tabs opened, the non-active tab
will not receive the incoming message but at this point we do not think
the technical trade-offs are worth it to support this feature. We
basically have to somehow exclude a client from an incoming message
which is not easy to do.
