We were attempting to fetch from last read but this is actually complicated to get right when you have a lot unread, as we might still have more to load after this but the last unread id is still the same and would make the user end up in a loop.
A previous change updated `ReviewableQueuedPost`'s `created_by`
to be consistent with other reviewable types. It assigns
the the creator of the post being queued to `target_created_by` and sets
the `created_by` to the creator of the reviewable itself.
This fix updates some of the `created_by` references missed during the
intial fix.
The store expects values for property names ending with `_id` to be a resource id
and `_ids` to be an array of resource ids.
This change ensures the store gracefully handles situations where an
embedded field with incompliant data structure sneaks its way to production.
Internal oneboxes to posts that contained oneboxed github links to
commits or PRs with long enough commit messages to have the `show-more`
and the `excerpt hidden` classes in their html were being stripped of
their content resulting in empty internal oneboxes.

This fixes a regression introduced in:
0b3cf83e3c
By default, only 10 members are highlighted on group cards. However,
joining/leaving a big group via the buttons on the group card results in
up to 50 members being highlighted. For large groups, this causes the card
to move off-screen.
This happens because, while the initial render explicitly fetches only 10
members, we don't seem to apply the same limit as part of the member
reload performed when a user leaves/joins via the buttons on the card.
This PR fixes that by only making the first 10 users available for
highlight regardless of the number of members loaded in the store.
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.
Using pinch-zoom on mobile devices with lightbox images can lead to scrolling of background content.
This change handles this by capturing the window.scrollY value when opening the lightbox, then when exiting we check if the scroll position has changed and reset it.
What is the context for this change?
Prior to this change, there is a bug in `TopicsController#reset_new`
where it does not dismiss new topics in sub-subcategories when the
`category_id` and `include_subcategories=true` params are present. This
is because the controller did not account for sub-subcategories when
fetching the category ids of the new topics that should be dismissed.
This commit fixes the problem by relying on the `Category.subcategory_ids` class
method which accounts for sub-subcategories.
This is happening because despite the user already existing in the forum, the `SingleSignOnRecord` doesn't exist and "require_activation" is set on the provider, causing us to skip looking for the email, and resulting in us creating a new User then seeing Validation failed: Primary email has already been taken when DiscourseConnect is attempting to make a new account.
We did some testing and saw that making one query per month is
cheaper than querying all chat messages at ones. Note that even
though the export job will be performing one query per month,
the exported messages will be streamed into a single CSV file, so
nothing changes from the user's point of view.
provide the ability to edit theme settings in the json editor, and also copy them as a text file so they can be pasted into another instance.

This is a fairly extensive update to add checklists and to reorganize the presented information so it is more accessible. Some info is relegated to links to docs on meta. For convenience and regular reference, this topic is now linked to from a GETTING STARTED button next to the site title as long as the site is in bootstrap mode.
This is extracted from #22390.
This patch introduces a scope to avoid duplication and a new method,
`Chat::Channel.find_by_id_or_slug` to allow finding a channel either by
its id or by its slug (or its category slug).
`Jobs::AutoJoinChannelBatch` was holding a lot of logic which should be in a service. Moreover, this refactoring is the opportunity to address a bug which could cause a duplicate key error.
From now when trying to insert a new membership it won't fail if a membership is already present.
Example error:
```
Job exception: ERROR: duplicate key value violates unique constraint "user_chat_channel_unique_memberships"
DETAIL: Key (user_id, chat_channel_id)=(1, 2) already exists.

Prior to this commit we were loading a large number of thread messages without any pagination. This commit attempts to fix this and also improves the following points:
- code sharing between channels and threads:
Attempts to reuse/share the code use in channels for threads. To make it possible part of this code has been extracted in dedicated helpers or has been improved to reduce the duplication needed.
Examples of extracted helpers:
- `stackingContextFix`: the ios hack for rendering bug when momentum scrolling is interrupted
- `scrollListToMessage`, `scrollListToTop`, `scrollListToBottom`: a series of helper to correctly scroll to a specific position in the list of messages
- better general performance of listing messages:
One of the main changes which has been made is to remove the computation of visible message during scroll, it will only happen when needed (update last read for example). This constant recomputation of `message.visible` on intersection observer event while scrolling was consuming a lot of CPU time.
Why this change?
In `PostDestroyer#make_previous_post_the_last_one` and
`Topic.reset_highest`, we have a query that looks something like this:
```
SELECT user_id FROM posts
WHERE topic_id = :topic_id AND
deleted_at IS NULL AND
post_type <> 4
#{post_type}
ORDER BY created_at desc
LIMIT 1
```
However, we currently don't have an index that caters directly to this
query. As a result, we have seen this query performing poorly on large
sites if the PG planner ends up using an index that is suboptimal for
the query.
This commit adds an index to the `posts` table on `topic_id` and then
`created_at`. For the query above, PG will be able to do a backwards
index scan efficiently.
Context of this change:
There are two site settings which an admin can configured to set the
default categories and tags that are shown for a new user. `default_navigation_menu_categories`
is used to determine the default categories while
`default_navigation_menu_tags` is used to determine the default tags.
Prior to this change when seeding the defaults, we will filter out the
categories/tags that the user do not have permission to see. However,
this means that when the user does eventually gain permission down the
line, the default categories and tags do not appear.
What does this change do?
With this commit, we have changed it such that all the categories and tags
configured in the `default_navigation_menu_categories` and
`default_navigation_menu_tags` site settings are seeded regardless of
whether the user's visibility of the categories or tags. During
serialization, we will then filter out the categories and tags which the
user does not have visibility of.
