Every time we load the RHS, we used to load the FULL thread always. Although
the actual ThreadViewer React component is virtualized, and the server side
API call is paginated, we still went through all the pages, to get the full
thread and passed it on to the ThreadViewer. This would be for first loads,
and subsequent loads of the same thread.
This was a bug originally, but then it was a necessity after we applied websocket event scope because
now we won't get emoji reactions of a thread if the user is not on the thread.
To fix that, we enhance the thread loading functionality by adding support for fetching
thread updates based on the UpdateAt timestamp. Now, for subsequent loads,
we only get the changed posts in a thread. The implementation:
- Adds new API parameters: fromUpdateAt and updatesOnly to the GetPostThread endpoint
- Updates database queries to support sorting and filtering by UpdateAt
- Implements thread state management to track the last update timestamp
- Adds client-side support to use incremental loading for improved performance
- Ensures proper validation for parameter combinations and error handling
This change enables more efficient thread loading, particularly for long threads
with frequent updates, by only fetching posts that have been updated since the
last view.
Caveats: For delta updates, the SQL query won't use the best index possible
because we have an index for (CreateAt, Id), but no index for (UpdateAt, Id).
However, from my tests, it is not as bad as it looks:
```
[loadtest] # EXPLAIN (ANALYZE, BUFFERS) SELECT * FROM Posts WHERE Posts.DeleteAt = 0 AND Posts.RootId = 'qbr5gctu9iyg8c36hpcq6f3w8e' AND Posts.UpdateAt > 1623445795824 ORDER BY UpdateAt ASC, Id ASC LIMIT 61;
QUERY PLAN
-------------------------------------------------------------------------------------------------------------------------------------------------
Limit (cost=8.31..8.31 rows=1 width=216) (actual time=0.047..0.049 rows=0 loops=1)
Buffers: shared hit=2
-> Sort (cost=8.31..8.31 rows=1 width=216) (actual time=0.044..0.045 rows=0 loops=1)
Sort Key: updateat, id
Sort Method: quicksort Memory: 25kB
Buffers: shared hit=2
-> Index Scan using idx_posts_root_id_delete_at on posts (cost=0.28..8.30 rows=1 width=216) (actual time=0.031..0.032 rows=0 loops=1)
Index Cond: (((rootid)::text = 'qbr5gctu9iyg8c36hpcq6f3w8e'::text) AND (deleteat = 0))
Filter: (updateat > '1623445795824'::bigint)
Buffers: shared hit=2
Planning:
Buffers: shared hit=3
Planning Time: 0.508 ms
Execution Time: 0.106 ms
(14 rows)
```
We still get an index scan with index cond. Although there's a filter element, but atleast we get the whole thread with the index.
My thinking is that while the whole thread might be large, but after that, updates on a thread should be incremental.
Therefore, we should be okay without adding yet another index on the posts table.
This is just the first step in what could be potentially improved further.
1. We shouldn't even be loading the full thread always. But rather let the virtualized viewer
load more posts on demand.
2. If a post has been just reacted to, then we need not send the whole post down, but just the
reaction. This further saves bandwidth.

* Add license load metric endpoint and UI indicator
Adds an API endpoint to calculate and return license usage as a load metric, and displays this metric in the About dialog. The metric is calculated as (MAU/licensed users)*100.
Additionally:
- Renamed function to be consistent with API endpoint name
- Added proper i18n strings for error messages and UI elements
* Fix TypeScript null check in about_build_modal.tsx
* MM-63728: Update OpenAPI documentation for license load metric
Update the OpenAPI documentation and code comments to correctly describe the license load metric calculation as using a multiplier of 1000 instead of percentage.

Modify the license load metric calculation to use floats throughout the computation process while still returning an integer result. This maintains the existing API but improves the precision of the calculation.

This change automatically removes options and sync attributes when
sanitizing fields that don't support them. As per values, it returns
an error when the value for a text type field is longer than the 64
characters limit we're currently applying.
The PR fixes a bug on the create CPA field endpoint that was causing
the attrs of the CPAField not to be decoded correctly.

* Adds a groupID filter to the property service methods
This allows the property service caller to directly ensure that a
given call is only going to affect a field or value that belongs to a
given group, instead of (for example) retrieving a property value
before deleting it by id to ensure that the value belongs to a
specific property group. The groupID filter is optional and has no
effect if called with the empty string value.
The changes also remove references to input sanitization on trimming
the whitespace for the CPA field names and validate at the API level
the input for the field patch endpoint.

When Channel iteration mode is enabled, we need to ensure that
channel scoped events do not fall through to the connIndex.All()
condition. This is possible because there are multiple hubs
in a given system. So a single event will flow through all of them
and in some hubs, a channel scoped event might not have any connections.
In that case, we need to stop processing further.
https://mattermost.atlassian.net/browse/MM-62960
```release-note
NONE
```
When we added iteration by channelID, this was a known tradeoff during that.
However, it has been observed that the regular connection removal function
creates considerable blocking of the processing loop, leading to high
CPU usage and API latencies.
To fix this, we add a reverse mapping of channelIDs to connections
and their positions in the slice. This helps us to remove the connection
from the slice without iteration.
Unfortunately, this still needs to iterate through all channelIDs
during invalidation of the channel member cache. However, the user
cache invalidation is not a regular activity. So it should be an acceptable
tradeoff to make.

```release-note
A new config knob ServiceSettings.EnableWebHubChannelIteration which allows a user to control the performance of websocket broadcasting. By default, this setting is turned off. If it is turned on, it improves the websocket broadcasting performance at the expense of poor performance when users join/leave a channel. It is not recommended to turn it on unless you have atleast 200,000 concurrent users actively using MM.

We add a new config setting to allow the admin to set a fixed
list of userIDs to track for all client side webapp metrics.
This gives the admin to get a deeper look at how the application
is behaving for a single user.
A new section in the system console is also added for the user
to edit this setting from the UI.

* Adds websocket messages to Custom Profile Attributes
The app layer now fires a websocket event as part of the operations
over Custom Profile Attribute fields and values. It updates as well
the Patch method for CPA values so all the changes are commited as
part of the same transaction.
To be able to do this last operation, the change adds methods to
upsert CPA values in both the store and the property service.
