Previously the code was very race condition prone leading to
odd failures in production
It was re-written in raw SQL to avoid conditions where rows
conflict on inserts
There is no clean way in ActiveRecord to do:
Insert, on conflict do nothing and return existing id.
This also increases test coverage, we were previously not testing
the code responsible for crawling external sites directly
We were getting errors like this in Reviewables in some cases:
```
ActiveRecord::StatementInvalid (PG::AmbiguousColumn: ERROR: column reference "category_id" is ambiguous
LINE 4: ...TRUE) OR (reviewable_by_group_id IN (NULL))) AND (category_i...
```
The problem that was making everything go boom is that plugins can add their own custom filters for Reviewables. If one is doing an INNER JOIN on topics, which has its own category_id column, we would get the above AmbiguousColumn error. The solution here is to just make all references to the reviewable columns in the list_for and viewable_by code prefixed by the table name e.g. reviewables.category_id.
This is so that, on a multisite cluster, when we handle a CDN request,
the hostname that is requested corresponds to one of the sites -
specifically the default site.
* FEATURE: Support for App Shortcuts Menu
This adds a list of shortcuts to a installed Discourse instance.
It can be accessed by right clicks or long press on the app icon.
See https://github.com/MicrosoftEdge/MSEdgeExplainers/blob/master/Shortcuts/explainer.md
List of possible follow ups include:
- Making it admin customizable
- Making it user customizable
- Using SVG icons from the site icon sprite
- Picking an accent color for icons
* FIX: Add type to shortcut menu icons
Previously we only changed sequence on ownership change, this
cause a race condition between tabs where user could type for a
long time without being warned of an out of date draft.
This change is a radical change and we should watch closely.
Code was already in place to track sequence on the client so no
changes are needed there.
Adding this from a review; I was using Discourse.currentUser which is frowned upon now.
Passing currentUser both for regular post menu buttons and extra buttons attached via the plugin API.
Lots of formatting/whitespace changes, best off reviewing with ?w=1
* Do not show "Uncategorized" category in topics list.
* Use "BreadcrumbList" only if topic is in a category.
* Add tags list as keywords to the first post.
* Add "dateModified" even if it is the same with "datePublished".
* Show "crawler-linkback-list" only if there are links to be shown.
* DEV: allows to define an ariaLabel on d-button
This topic also adds this function to topic-footer-buttons, simplifies the whole logic of titile/label/arialabel in d-button and adds tests for these properties.
* typo
In production `title` was set to undefined causing a
discrepancy between originalTitle and title
This attempts to work around the issue in the production bundle
