On the topic view route we query for reviewables of each post in the stream,
using a query that filters on two unindexed columns. This results in a Parallel Seq Scan
over all rows, which can take quite some time (~20ms was seen) on forums with lots of flags
After index is added PostgreSQL planner opts for a simple Index Scan and runs in sub 1ms.

After thinking about it, I worry that this will potentially leave a site
setting set when people hit ctrl-c ... feels a tiny bit risky, so leaving
it out.
This commit adds a new site setting "allowed_onebox_iframes". By default, all onebox iframes are allowed. When the list of domains is restricted, Onebox will automatically skip engines which require those domains, and use a fallback engine.
This helps us out in a few ways:
1. It lessens our reliance on jQuery
2. It's slightly less code because it omits options we don't use
3. It is one less library to import and put into ES6 modules
This is a follow-up for f51ccea028 because specs were failing on macOS. macOS uses bsdtar by default and the --transform option isn't supported by bsdtar. But the -s option is and it works the same.
didRender will be called each time the widget is rendered
willRerender will be called the second time a widget is rendered to give an opportunity to clean some state before the tree is replaced
Originally disabled in 0c0192e. Upload specs now use separate paths for each spec worker.
Fixes an issue in UploadRecovery#recover_from_local – it didn't take into account the testing infix (e.g. test_0) in the uploads/tombstone paths.
With the addition of `PostSearchData#private_message`, a partial
index consisting of only search data from regular posts can be created.
The partial index helps to speed up searches on large sites since PG
will not have to do an index scan on the entire search data index which
has shown to be a bottle neck.
- Introduces uploads:delete_missing_s3 which can be used to "give up" and
delete broken records from the database
- Fixes a bug in fix_missing_s3 - crashing on deleted posts
- Adds more info to analyze_missing_s3
These fields are required when using the UI and if `suspend_until`
params isn't used the user never is actually suspended so we should
require these fields when suspending a user.
* Category Page / Tag Class Additions
These additions add:
-the name of the tag as a css class to discourse tags.
-'pinned' as a css class to pinned topics in the category view
eg repro before:
- visit http://pr-discourse.test/top/weekly?f=foo
- select another period in the period chooser
- f=foo was gone
After this commit it should still be present
This commit is addressing an issue where it is possible that there could
be multiple topic timer jobs running to close a topic or a weird race
condition state causing a topic that was just closed to be re-opened.
By removing the logic from the Topic Timer model into the Topic Timer
controller endpoint we isolate the code that is used for setting an
auto-open or an auto-close timer to just that functionality making the
topic timer background jobs safer if multiple are running.
Possibly in the future if we would like this logic back in the model a
refactor will be needed where we actually pass in the auto-close and
auto-open action instead of mixing it with the close and open
action that is currently being passed to the controller.
