We have no way of detecting if a browser window is behind another window
or off screen on a virtual desktop.
In some cases we may want events to be delivered quicker to the browser.
Specifically a user may still have a window in view but is not interacting.
This gives users 20 minutes of extra "long polling time" prior to shifting
to short polling.
Even though `type` is an alias for `method`, we have custom logic in `/discourse/lib/ajax` that checks only `type`, and ~200 other ajax calls in the codebase already use `type` param.
This set of tests cleared the emoji store *before* each test, while the other set - *after*. So if these were run first, they would break a single test from the other set.
Checking if all records have been imported uses a temp table in PostgreSQL. This fails when pgbouncer is used unless the temp table is created inside a transaction.
* FIX: Perform crop using user-specified image sizes
It used to resize the images to max width and height first and then
perform the crop operation. This is wrong because it ignored the user
specified image sizes from the Markdown.
* DEV: Use real images in test
Previously we would consider a user "present" and "last seen" if the
browser window was visible.
This has many edge cases, you could be considered present and around for
days just by having a window open and no screensaver on.
Instead we now also check that you either clicked, transitioned around app
or scrolled the page in the last minute in combination with window
visibility
This will lead to more reliable notifications via email and reduce load of
message bus for cases where a user walks away from the terminal
Get rid of harmful each loop over uploads to update. Instead we put all the unique access control posts for the uploads into a map for fast access (vs using the slow .find through array) and look up the post when it is needed when looping through the uploads in batches.
On a Discourse instance with ~93k uploads, a simplified version of the old method takes > 1 minute, and a simplified version of the new method takes ~18s and uses a lot less memory.
If the “secure media” site setting is enabled then ALL files uploaded to Discourse (images, video, audio, pdf, txt, zip etc. etc.) will follow the secure media rules. The “prevent anons from downloading files” setting will no longer have any bearing on upload security. Basically, the feature will more appropriately be called “secure uploads” instead of “secure media”.
This is being done because there are communities out there that would like all attachments and media to be secure based on category rules but still allow anonymous users to download attachments in public places, which is not possible in the current arrangement.
