Setting a key/value pair in DistributedCache involves waiting on the
write to Redis to finish. In most cases, we don't need to wait on the
setting of the cache to finish. We just need to take our return value
and move on.
This allows us to do DISTINCT on the topic_id to remove
duplicates (e.g. in extensions to the report SQL), and
also introduces an additional_join_sql string to allow
extensions to JOIN additional tables.
* FIX: Ignore `allowlistgeneric` Onebox image sizes
The size of an image contained within the preview pane of a Composer window may vary depending on the configuration of the browser displaying the Composer (e.g., dimension of browser window, zoom level, etc.).
Presently, the dimensions of the images from the browser creating the post containing the Onebox will be used to render the Onebox to anyone who views the post. It is safer to let the backend figure out the dimensions of the images. Therefore, exclude `.onebox.allowlistedgeneric` images from the list of `image_sizes` sent to the backend.
* DEV: Replace jQuery selector with pure JS
* DEV: remove more jQuery
This improves the display of available tags in categories that are
configured to require at least (x) tags from a tag group.
There are two changes included:
- regular users will now see all the available tags in the required tag
group (previously they could see a max. of 5 tags)
- staff users will now see the tags from the required tag group when
the tag group contains more tags than the default limit (also set to 5)
Both changes only apply to the default query (i.e. no search terms).
After editing a post, it is refreshed by two ways. One of them is
triggered by the client side which will route the client to the edited
post and force a reload this way. The other way is via Message Bus.
This commit ignores both of the ways and tries to update the post
immediately and then refresh the post stream.
It used to require SiteSetting.min_trust_level_to_allow_invite to
invite a user to a group, even if the user existed and the inviter was
a group owner.
Users who use encoded slugs on their sites sometimes run into 500 error when pasting a link to another topic in a post. The problem happens when generating a backward "reflection" link that would appear in a linked topic. Link URL restricted on the database level to 500 chars in length. At first glance, it should work since we have a restriction on topic title length.
But it doesn't work when a site uses encoded slugs, like here (take a look at the URL). The link to a topic, in this case, can be much longer than 500 characters.
By the way, an error happens only when generating a "reflection" link and doesn't happen with a direct link, we truncate that link. It works because, in this case, the original long link is still present in the post body and can be used for navigation. But we can't do the same for backward "reflection" links (without rewriting their implementation), the whole link must be saved to the database.
The simplest and cleanest solution will be just to remove the restriction on the database level. Abuse is impossible here since we are already protected by the restriction on topic title length. There aren’t performance benefits in using length-constrained columns in Postgres, in fact, length-constrained columns need a few extra CPU cycles to check the length when storing data.
When a topic is fully merged into another topic we close it and schedule its deleting. But, because of a bug, if the merged topic contains some moderator actions or small actions it won't be merged. This change fixes this problem.
An important note: in general, we don't want to close a topic after moving posts if it still contains some regular posts or whispers. But when we are moving posts to a private message we don't want the notice about it to be publicly visible. So we use whispers with action_code == 'split_topic' instead of small_actions in such cases and we should ignore this specific kind of whispers when decide if we should close the merged topic.
It was not clear that replace watched words can be used to replace text
with URLs. This introduces a new watched word type that makes it easier
to understand.
The query is being executed each time we try and generate the link path
for a stylesheet within the duration of a reqeust. Categories are not
updated that often so repeating this query multiple times a request is
wasteful.
At the time of this commit, there is a `publish_discourse_stylesheet`
ActiveRecord callback on the `Category` model which clears the cache of
`Stylesheet::Manager` each time a category is saved.
`SvgSprite.custom_sprite_paths` does not just fetch custom SVG sprite
from themes. It also picks up any custom svg icons from a pre-defined
plugin folder.
Follow-up to 0700e9382d
The XML parsing of SVGs is done whenever the cache expires or on the
first load after a reboot. In one of our production instance, parsing
ranges from 30ms to 70ms which is not ideal. Instead, we've decided to
make a small memory trade off here by memoizing the core SVGs once on
boot to avoid parsing of the SVG files during the duration of a request.
The memozied hash will take up 57440 bytes or 0.05744 megabytes in size.
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).)

* FIX: return an empty result if response from Amazon is missing attributes
Check we have the basic attributes requires to construct a Onebox for Amazon.
This is an attempt to handle scenarios where we receive a valid 200-status response from an Amazon request that does not include the data we’re expecting.

Refactors `TrustLevel` and moves translations from server to client
Additional changes:
* "staff" and "admin" wasn't translatable in site settings
* it replaces a concatenated string with a translation
* uses translation for trust levels in users_by_trust_level report
* adds a DB migration to rename keys of translation overrides affected by this commit
In Ember CLI, the vendor bundler includes Ember/jQuery, so this brings
our app closer to that configuration.
We have a couple pages (Reset Password / Confirm New Email) where we need
`ember_jquery` without vendor so the file still exists for those cases.
Some specs failed when `LOAD_PLUGINS=1` was set while migrating the test DB and the narrative-bot plugin disabled the `send_welcome_message` site setting.
Previous to this change we would switch off MessageBus updating after 20
minutes.
This ensures that when the user becomes present again we turn on long polling.
Without long polling updates can be delayed for minutes.
