This `description` field on a theme is returned from the server side and
needn't be calculated in the front end. I tested in the UX and seems to
work well.
(This change could be considered a little risky so we should keep an eye
on it.)
The core issue here is that sometimes as far as the router was concerned
we had transitioned to a route even if a Topic model was still in the
process of loading. In this case the callback could not retrieve the
correct title yet because it had not loaded.
This fix returns a promise from `setupController` when visiting a topic,
which will have the router block until the topic is loaded. This means
that the transition never triggers until the topic title is present.
Note: adding a test for this is basically impossible - it was super hard
to reproduce even in a browser.
This changes PG text search to only match the given title against
lexemes that are formed from the title. Likewise, the given raw will
only be matched against lexemes that are formed from the post's raw.
Because previous migration was already deployed and some databases were already migrated, I needed to add some conditions to the migration.
Previous migration - https://github.com/discourse/discourse/blob/master/db/post_migrate/20200629232159_rename_path_whitelist_to_allowed_paths.rb
What will happen in a scenario when previous migration was not run.
1. column allowed_paths will be created
2. allowed_path will be populated with data from path_whitelist
3. path_whitelist column will be dropped
What will happen in a scenario when previous migration was already run.
1. column allowed_paths will not be created because already exists - `unless column_exists?(:embeddable_hosts, :allowed_paths)`
2. Data will not be copied because path_whitelist is missing - `if column_exists?(:embeddable_hosts, :path_whitelist) && column_exists?(:embeddable_hosts, :allowed_paths)`
3. path_whitelist column deletion will be skipped - `if column_exists?(:embeddable_hosts, :path_whitelist)`
Useful if you want to, say, have your unicorn listen on a Unix domain
socket, rather than a TCP port, or you want to be able to bind to a
single address other than 127.0.0.1.
If a user posted a topic and Akismet decided it was spam, the topic gets deleted and put into the review queue. If a category moderator for that category marked the post/topic as "Not Spam" the topic did not get recovered correctly because Guardian.new(@user).can_review_topic?(@post.topic) returned false incorrectly because the topic was deleted.
We do prefix matching in search so there is no need to inject the extra
terms.
Before:
```
"'discourse':10,11 'discourse.org':10,11 'org':10,11 'test':8A,10,11 'test.discourse.org':10,11 'titl':4A 'uncategor':9B"
```
After:
```
"'discourse.org':10,11 'org':10,11 'test':8A 'test.discourse.org':10,11 'titl':4A 'uncategor':9B"
```
This code was intended to bypass iterating through tags in absence of a new
or unread topic.
Instead it always fired cause it was checking for function existence which
was clearly always true.
This involves a little refactoring of how our `defaultHomepage()` works.
It previously would check the meta tag / site settings each time it was
called but now it only checks once on application boot.
