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.

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%.

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.
The widget should accept the disabled option.
In that case, CSS class "disabled".
In addition, after click dropdown will not be shown.
Also, the option to disable a specific value in a dropdown is included
…and just prioritize the current one, instead of hiding other categories.
Context: when you open the composer by clicking "New Topic" button when in a category, or by clicking "New Topic" in the share-popup, the category selector shows only the current category and its children (and "Uncategorized"). You can still find other categories, but you have to search by name.
This PR changes that, so you now can see all the categories in the dropdown, and those that are relevant (again: current, children and uncategorized) are displayed before all other categories.
tldr: don't make choosing other categories harder - make choosing relevant ones easier.
1. It defaults to `cache: true` already
2. Setting it to `false` for non-GET request doesn't do anything
3. We were correcting `cache: false` GET requests to use `cache: true`
…so setting it to anything at all, for any type of request doesn't make sense (anymore)
On the web, we display only an excerpt in a monospace font and the rest
of the body is hidden under ellipsis. The email displayed both of them
and it did not use the same style. This commit leaves only the excerpt
in emails and makes it use a monospace font to display it.
The excerpt field in the database is constrained to 1000 chars in length. To support this constraint we added a restriction that the topic_excerpt_maxlength setting must be between 0 and 999.
Unfortunately, sometimes it doesn’t work because:
- topic_excerpt_maxlength restricts the length of a visible to user excerpt. But we HTML-escape text before saving. If an excerpt contains & it’ll be &. One character for the user but 5 characters to save to the database. So if topic_excerpt_maxlength is set to 999 it’s not so hard to have an excerpt of for example 1003 characters in length and run into this issue.
- It’s possible to define a custom excerpt for a topic. Such excerpts bypass check for a length. So if the user defines a too long custom excerpt he will run into this issue.
Removing the constraint on the database level solves the problem. But we still need the constraint for topic_excerpt_maxlength on the setting page, because too long excerpts would make UI wonky.
When the client received a new notification, it prioritized only PM
notifications instead of maintaining the priority order. Later, the
check for missing notification deleted all notifications that were
in the wrong order because it could not match the IDs.
The correct order puts high_priority AND unread notifications first.
Low priority or read notifications (including high priority, but read
notifications) come after.

A non-staff user cannot post to a closed topic, so we should not
show them the modal asking "Which topic do you want to reply to?"
This also fixes an issue I ran into while testing the above change, in
Ember CLI an error was being raised because related messages were being
set inside a computed property.
When a topic is fully merged into another topic we close it. Now we want also to set a timer for deleting this topic. By default, stub topics will be deleted in 7 days. Users can change this period or disable auto-deleting by setting the period to 0.
