Summary: Fixes T430. Fixes T4834. Obsoletes D7641. Currently, we do some things less-well than we could: - We just let the browser queue and prioritize requests, so if you load a revision with 50 changes and then click "Award Token", the action blocks until the changes load in most/all browsers. It would be better to prioritize this action and queue it immediately. - Similarly, changes tend to load in order, even if the user has clicked to a specific file. When the user expresses a preference for a specific file, we should prioritize it. - We show a spinning GIF when waiting on requests. This is appropriate for some types of reuqests, but distracting for others. To fix this: - Queue all (or, at least, most) requests into a new queue in JX.Router. - JX.Router handles prioritizing the requests. Principally: - You can submit a request with a specific priority (500 = general content loading, 1000 = default, 2000 = explicit user action) and JX.Router will get the higher stuff fired off sooner. - You can name requests and then adjust their prorities later, if the user expresses an interest in specific results. - Only use the spinner gif for "workflow" requests, which is bascially when the user clicked something and we're waiting on the server. I think it's useful and not-annoying in this case. - Don't show any status for draft requests. - For content requests, show a subtle hipster-style top loading bar. Test Plan: - Viewed a diff with 93 changes, and clicked award token. - Prior to this patch, the action took many many seconds to resolve. - After this patch, it resolves quickly. - Viewed a diff with 93 changes and saw a pleasant subtle hipster-style loading bar. - Viewed a diff with 93 changes and typed some draft text. Previews populated fairly quickly and there was no spinner. - Viewed a diff with 93 changes and clicked something with workflow, saw a spinner after a moment. - Viewed a diff with 93 changes and clicked a file in the table of contents near the end of the list. - Prior to this patch, it took a long time to show up. - After this patch, it loads directly.
