We've seen in some communities abuse of user profile where bios and other fields are used in malicious ways, such as malware distribution. A common pattern between all the abuse cases we've seen is that the malicious actors tend to have 0 posts and have a low trust level.
To eliminate this abuse vector, or at least make it much less effective, we're making the following changes to user profiles:
1. Anonymous, TL0 and TL1 users cannot see any user profiles for users with 0 posts except for staff users
2. Anonymous and TL0 users can only see profiles of TL1 users and above
Users can always see their own profile, and they can still hide their profiles via the "Hide my public profile" preference. Staff can always see any user's profile.
Internal topic: t/142853.
It splits the hide_profile_and_presence user option and the default_hide_profile_and_presence site setting for more granular control. It keeps the option to hide the profile under /u/username/preferences/interface and adds the presence toggle in the quick user menu.

When a post has some replies, and the user click on the button to show them, we would load ALL the replies. This could lead to DoS if there were a very large number of replies.
This adds support for pagination to these post replies.

FIX: Duplicated parent posts
DEV: Query refactor
Currently, categories support designating only 1 group as a moderation group on the category. This commit removes the one group limitation and makes it possible to designate multiple groups as mods on a category.

* FEATURE: Clean up previously logged information after permanently deleting posts
When soft deleteing a topic or post, we will log some details in the
staff log, including the raw content of the post. Before this commit, we
will not clear the information in these records. Therefore, after
permanently deleting the post, `UserHistory` still retains copy of the
permanently deleted post. This is an unexpected behaviour and may raise
some potential legal issues.
This commit adds a behavior that when a post is permanently deleted, the
details column of the `UserHistory` associated with the post will be
overwritten to "(permanently deleted)". At the same time, for permanent
deletion, a new `action_id` is introduced to distinguish it from soft
deletion.

Note this may have performance issues in some cases, will need to be monitored
Previous to this change we were bracketing on 50 id windows. They may end up
having zero posts we are searching for leading to posts.rss and .json returning
no results.
- avoids Post.last.id which is expensive
- order by id desc which is better cause we bracket on id
When a post is created by an incoming email, we show
an envelope icon on it which then opens a modal with the
raw email contents. Previously this was staff (admin+mod)
only, but now this commit adds the `view_raw_email_allowed_groups`
site setting, so any group can be added to give users permission
to see this.
For performance reasons we don't automatically add fabricated users to trust level auto-groups. However, when explicitly passing a trust level to the fabricator, in 99% of cases it means that trust level is relevant for the test, and we need the groups.
This change makes it so that when a trust level is explicitly passed to the fabricator, the auto-groups are refreshed. There's no longer a need to also pass refresh_auto_groups: true, which means clearer tests, fewer mistakes, and less confusion.
We're changing the implementation of trust levels to use groups. Part of this is to have site settings that reference trust levels use groups instead. It converts the min_trust_level_to_tag_topics site setting to tag_topic_allowed_groups.

A bug that allowed TL1 to convert other's posts to wiki.
The issue was introduced in this PR: https://github.com/discourse/discourse/pull/24999/files
The wiki can be created if a user is TL3 and it is their own post - default 3 for setting `SiteSetting.min_trust_to_allow_self_wiki`
In addition, a wiki can be created by staff and TL4 users for any post.
Using min_trust_to_create_topic and create_topic_allowed_groups together was part of #24740
Now, when plugins specs are fixed, we can safely remove that part of logic.
We're changing the implementation of trust levels to use groups. Part of this is to have site settings that reference trust levels use groups instead. It converts the min_trust_to_flag_posts site setting to flag_post_allowed_groups.
Note: In the original setting, "posts" is plural. I have changed this to "post" singular in the new setting to match others.

The most common thing that we do with fab! is:
fab!(:thing) { Fabricate(:thing) }
This commit adds a shorthand for this which is just simply:
fab!(:thing)
i.e. If you omit the block, then, by default, you'll get a `Fabricate`d object using the fabricator of the same name.
Why this change?
The `PostsController#create` action allows arbitrary topic custom fields
to be set by any user that can create a topic. Without any restrictions,
this opens us up to potential security issues where plugins may be using
topic custom fields in security sensitive areas.
What does this change do?
1. This change introduces the `register_editable_topic_custom_field` plugin
API which allows plugins to register topic custom fields that are
editable either by staff users only or all users. The registered
editable topic custom fields are stored in `DiscoursePluginRegistry` and
is called by a new method `Topic#editable_custom_fields` which is then
used in the `PostsController#create` controller action. When an unpermitted custom fields is present in the `meta_data` params,
a 400 response code is returned.
2. Removes all reference to `meta_data` on a topic as it is confusing
since we actually mean topic custom fields instead.
In #20135 we prevented invalid inputs from being accepted in category setting form fields on the front-end. We didn't do anything on the back-end at that time, because we were still discussing which path we wanted to take. Eventually we decided we want to move this to a new CategorySetting model.
This PR moves the require_topic_approval and require_reply_approval from custom fields to the new CategorySetting model.
This PR is nearly identical to #20580, which migrated num_auto_bump_daily, but since these are slightly more sensitive, they are moved after the previous one is verified.
What is the problem here?
In multiple controllers, we are accepting a `limit` params but do not
impose any upper bound on the values being accepted. Without an upper
bound, we may be allowing arbituary users from generating DB queries
which may end up exhausing the resources on the server.
What is the fix here?
A new `fetch_limit_from_params` helper method is introduced in
`ApplicationController` that can be used by controller actions to safely
get the limit from the params as a default limit and maximum limit has
to be set. When an invalid limit params is encountered, the server will
respond with the 400 response code.
Performing a `Delete User`/`Delete and Block User` reviewable actions for a
queued post reviewable from the `review.show` route results in an error
popup even if the action completes successfully.
This happens because unlike other reviewable types, a user delete action
on a queued post reviewable results in the deletion of the reviewable
itself. A subsequent attempt to reload the reviewable record results in
404. The deletion happens as part of the call to `UserDestroyer` which
includes a step for destroying reviewables created by the user being
destroyed. At the root of this is the creator of the queued post
being set as the creator of the reviewable as instead of the system
user.
This change assigns the creator of the reviewable to the system user and
uses the more approapriate `target_created_by` column for the creator of the
post being queued.

When a post is created using the API and goes into the review queue, we
would return a 'null' string in the response which isn't valid JSON.

Prior to this change, we were parsing `Post#cooked` every time we
serialize a post to extract the usernames of mentioned users in the
post. However, the only reason we have to do this is to support
displaying a user's status beside each mention in a post on the client side when
the `enable_user_status` site setting is enabled. When
`enable_user_status` is disabled, we should avoid having to parse
`Post#cooked` since there is no point in doing so.
We show live user status on mentions starting from a76d864. But status didn’t appear on the post that appears on the bottom of the topic just after a user posted it (status appeared only after page reloading). This adds status to just posted posts.
* DEV: Remove enable_whispers site setting
Whispers are enabled as long as there is at least one group allowed to
whisper, see whispers_allowed_groups site setting.
* DEV: Always enable whispers for admins if at least one group is allowed.
This commit excludes posts from hidden topics from the latest posts and user activity RSS feeds. Additionally, it also excludes small actions from the first one.
cf. e62e93f83a
This PR also makes it so `bot` (negative ID) and `system` users are always allowed
to send PMs, since the old conditional was just based on `enable_personal_messages`
When tagging is enabled, we were correctly serializing tags by their name. However, when tagging was disabled we were attempting to serialize an entire Tag object which raises an error since ee07f6da7d.
https://meta.discourse.org/t/232885
Some errors (e.g. InvalidAccess) are rendered with `include_ember: true`. Booting the ember app requires that the 'preload' data is rendered in the HTML.
If a particular route was configured to `skip_before_action :preload_json`, and then went on to raise an InvalidAccess error, then we'd attempt to render the Ember app without the preload json. This led to a blank screen and a client-side error.
This commit ensures that error pages will fallback to the no_ember view if there is no preload data. It also adds a sanity check in `discourse-bootstrap` so that it's easier for us to identify similar errors in future.
* FIX: Posts can belong to hard-deleted topics
This was a problem when serializing deleted posts because they might
belong to a topic that was permanently deleted. This caused to DB
lookup to fail immediately and raise an exception. In this case, the
endpoint returned a 404.
* FIX: Remove N+1 queries
Deleted topics were not loaded because of the default scope that
filters out all deleted topics. It executed a query for each deleted
topic.
This commit migrates all bookmarks to be polymorphic (using the
bookmarkable_id and bookmarkable_type) columns. It also deletes
all the old code guarded behind the use_polymorphic_bookmarks setting
and changes that setting to true for all sites and by default for
the sake of plugins.
No data is deleted in the migrations, the old post_id and for_topic
columns for bookmarks will be dropped later on.
This will make future changes to the 'pull hotlinked images' system easier. This commit should not introduce any functional change.
For now, the old post_custom_field data is kept in the database. This will be dropped in a future commit.
* FEATURE: use canonical links in posts.rss feed
Previously we used non canonical links in posts.rss
These links get crawled frequently by crawlers when discovering new
content forcing crawlers to hop to non canonical pages just to end up
visiting canonical pages
This uses up expensive crawl time and adds load on Discourse sites
Old links were of the form:
`https://DOMAIN/t/SLUG/43/21`
New links are of the form
`https://DOMAIN/t/SLUG/43?page=2#post_21`
This also adds a post_id identified element to crawler view that was
missing.
Note, to avoid very expensive N+1 queries required to figure out the
page a post is on during rss generation, we cache that information.
There is a smart "cache breaker" which ensures worst case scenario is
a "page drift" - meaning we would publicize a post is on page 11 when
it is actually on page 10 due to post deletions. Cache holds for up to
12 hours.
Change only impacts public post RSS feeds (`/posts.rss`)
