Why this change?
Prior to this change, dismissing unreads posts did not publish the
changes across clients for the same user. As a result, users can end up
seeing an unread count being present but saw no topics being loaded when
visiting the `/unread` route.
* FEATURE: Inline topic summary. Cached version accessible to everyone.
Anons and non-members of the `custom_summarization_allowed_groups_map` groups can see cached summaries for any accessible topic. After the first 12 hours and if the posts to summarize have changed, allowed users clicking on the button will automatically re-generate it.
* Ensure chat summaries work and prevent model hallucinations when there are no messages.
Updates the interface for implementing summarization strategies and adds a cache layer to summarize topics once.
The cache stores the final summary and each chunk used to build it, which will be useful when we have to extend or rebuild it.
* FEATURE: Content custom summarization strategies.
This PR establishes a pattern for plugins to register alternative ways of summarizing content by extending a class that defines an interface.
Core controls which strategy we'll use and who has access to it through the `summarization_strategy` and `custom_summarization_allowed_groups`. It also defines the UI for summarizing topics.
Other plugins can access this summarization mechanism and implement their features, removing cross-plugin customizations, as it currently happens between chat and the discourse-ai plugin.
* Group membership validation and rate limiting
* Work with objects instead of classes
* Port summarization feature from discourse-ai to chat
* Rename available summaries to 'Top Replies' and 'Summary'
Display modal for combined new and unread view with options:
- [x] Dismiss new topics
- [x] Dismiss new posts
- [ ] Stop tracking these topics so they stop appearing in my new list
When a user chooses to move a topic/message to an existing topic/message, they can now opt to merge the posts chronologically (using a checkbox in the UI).
The #pluck_first freedom patch, first introduced by @danielwaterworth has served us well, and is used widely throughout both core and plugins. It seems to have been a common enough use case that Rails 6 introduced it's own method #pick with the exact same implementation. This allows us to retire the freedom patch and switch over to the built-in ActiveRecord method.
There is no replacement for #pluck_first!, but a quick search shows we are using this in a very limited capacity, and in some cases incorrectly (by assuming a nil return rather than an exception), which can quite easily be replaced with #pick plus some extra handling.
* FIX: Ensure soft-deleted topics can be deleted
The topic was not found during the deletion process because it was
deleted and `@post.topic` was nil.
* DEV: Use @topic instead of finding the topic every time
This can no longer be used from the user interface and could be used to
generate useless topic invites notifications. This commit adds site
setting max_topic_invitations_per_minute to prevent invite spam.
Hard deleting topics that contained soft deleted posts or small actions
used to create orphan posts because only the first post was hard
deleted. This commit adds an error message if there are still posts left
in the topic that must be hard deleted first or hard deletes all small
actions too immediately (there is no other way of hard deleting a small
action because there is no wrench menu).
Before, whispers were only available for staff members.
Config has been changed to allow to configure privileged groups with access to whispers. Post migration was added to move from the old setting into the new one.
I considered having a boolean column `whisperer` on user model similar to `admin/moderator` for performance reason. Finally, I decided to keep looking for groups as queries are only done for current user and didn't notice any N+1 queries.
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.
* DEV: Allow params to be passed on topic redirects
There are several places where we redirect a url to a standard topic url
like `/t/:slug/:topic_id` but we weren't always passing query parameters
to the new url.
This change allows a few more query params to be included on the
redirect. The new params that are permitted are page, print, and
filter_top_level_replies. Any new params will need to be specified.
This also prevents the odd trailing empty page param that would
sometimes appear on a redirect. `/t/:slug/:id.json?page=`
* rubocop: fix missing space after comma
* fix another page= reference
This feature was rarely used, could be used for spamming users and was
impossible to add a context to why the user was notified of a topic. A
simple private messages that includes the link and personalized message
can be used instead.
* DEV: Show only top level replies
Adds a new query param to the topic view so that we can filter out posts
that aren't top level replies. If a post is a reply to another post
instead of the original topic post we should not include it in the
response if the `filter_top_level_replies` query param is present.
* add rspec test
This commit handles the edge case where a draft is lost with no warnings if the user edits the title (or category/tags) of a topic while they're replying.to the same topic. Repro steps are as follows:
1. Start replying to a topic and type enough to get a draft saved.
2. Scroll up to the topic title and click the pencil icon next to the topic title, change the title, category and/or tags, and then save the changes.
3. Reload the page and you'll see that the draft is gone.
This happens because we only allow 1 draft per topic per user and when you edit the title of a topic that you're replying to, from the server perspective it'll look like as if you've submitted your reply so it will advance the draft sequence for the topic and delete the draft.
The fix in this commit makes `PostRevisor` skip advancing the draft sequence when a topic's title is edited using the pencil button next to the title.

* 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.

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 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.
This partially reverts commit ddb458343d.
Seeing performance degrade on larger sites so back to drawing board on
this one. Instead of the DISTINCT LEFT JOIN, we switch back to
IN(subquery).
First reported in https://meta.discourse.org/t/-/202482/19
There are two optimizations being applied here:
1. Fetch a user's group ids in a seperate query instead of including it
as a sub-query. When I tried a subquery, the query plan becomes very
inefficient.
1. Join against the `topic_allowed_users` and `topic_allowed_groups`
table instead of doing an IN against a subquery where we UNION the
`topic_id`s from the two tables. From my profiling, this enables PG to
do a backwards index scan on the `index_topics_on_timestamps_private`
index.
This commit fixes a bug where listing all messages was incorrectly
excluding topics if a topic has been archived by a group even if the
user did not belong to the group.
This commit also fixes another bug where dismissing private messages
selectively was subjected to the default limit of 30.
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.
Follow-up to fc1fd1b416
Since ad3ec5809f when a user chooses
the Dismiss New... option in the New topic list, we send a request
to topics/reset-new.json with ?tracked=false as the only parameter.
This then uses Topic as the scope for topics to dismiss, with no
other limitations. When we do topic_scope.pluck(:id), it gets the
ID of every single topic in the database (that is not deleted) to
pass to TopicsBulkAction, causing a huge query with severe performance
issues.
This commit changes the default scope to use
`TopicQuery.new(current_user).new_results(limit: false)`
which should only use the topics in the user's New list, which
will be a much smaller list, depending on the user's "new_topic_duration_minutes"
setting.
ATM it only implements server side of it, as my need is for automation purposes. However it should probably be added in the UI too as it's unexpected to have pinned_until and no bannered_until.
When dismissing new topics for the Tracked filter, the dismiss was
limited to 30 topics which is the default per page count for TopicQuery.
This happened even if you specified which topic IDs you were
selectively dismissing. This PR fixes that bug, and also moves
the per_page_count into a DEFAULT_PER_PAGE_COUNT for the TopicQuery
so it can be stubbed in tests.
Also moves the unused stub_const method into the spec helpers
for cases like this; it is much better to handle this in one place
with an ensure. In a follow up PR I will clean up other specs that
do the same thing and make them use stub_const.
I merged this PR in yesterday, finally thinking this was done https://github.com/discourse/discourse/pull/12958 but then a wild performance regression occurred. These are the problem methods:
1aa20bd681/app/serializers/topic_tracking_state_serializer.rb (L13-L21)
Turns out date comparison is super expensive on the backend _as well as_ the frontend.
The fix was to just move the `treat_as_new_topic_start_date` into the SQL query rather than using the slower `UserOption#treat_as_new_topic_start_date` method in ruby. After this change, 1% of the total time is spent with the `created_in_new_period` comparison instead of ~20%.

History:
Original PR which had to be reverted **https://github.com/discourse/discourse/pull/12555**. See the description there for what this PR is achieving, plus below.
The issue with the original PR is addressed in 92ef54f402
If you went to the `x unread` link for a tag Chrome would freeze up and possibly crash, or eventually unfreeze after nearly 10 mins. Other routes for unread/new were similarly slow. From profiling the issue was the `sync` function of `topic-tracking-state.js`, which calls down to `isNew` which in turn calls `moment`, a change I had made in the PR above. The time it takes locally with ~1400 topics in the tracking state is 2.3 seconds.
To solve this issue, I have moved these calculations for "created in new period" and "unread not too old" into the tracking state serializer.
When I was looking at the profiler I also noticed this issue which was just compounding the problem. Every time we modify topic tracking state we recalculate the sidebar tracking/everything/tag counts. However this calls `forEachTracked` and `countTags` which can be quite expensive as they go through the whole tracking state (and were also calling the removed moment functions).
I added some logs and this was being called 30 times when navigating to a new /unread route because `sync` is being called from `build-topic-route` (one for each topic loaded due to pagination). So I just added a debounce here and it makes things even faster.
Finally, I changed topic tracking state to use a Map so our counts of the state keys is faster (Maps have .size whereas objects you have to do Object.keys(obj) which is O(n).)
