Returns 10-20ms consistently on i7-4770k, on shared hosts the cost
could easily reach 40ms
This code simply calculates the strings
/categories
/guidelines
/tos
/privacy
It is ludicrous to spend this enormous amount of work just to calculate
4 strings.
I do not know if this is something specific about Discourse or a bug in
Rails (I tried without the main_app prefix and got similar results),
regardless we can got to avoid these _path APIs for now
Discovered this when running a flamegraph on our home page.
Our plugins use rails engines which are mounted against the main
application's `ApplicationController`. This works great but path helpers
need to reference `main_app` in order for it not to blow up.
- add microdata based on schema.org

- FIX: pass the CSRF token in a query parameter since IE9 doesn't pass it in the headers
- FIX: display error messages comming from the server when there is one over the default error message
- FIX: HACK around IE9 security issue when clicking a file input via JavaScript (use a label and set `visibility:hidden` on the input)
- FIX: hide the "cancel" upload on IE9 since it's not supported
- FIX: return "text/plain" content-type when uploading a file for IE9 in order to prevent it from displaying the save dialog
- FIX: check the maximum file size on the server 💥
- update jQuery File Upload Plugin to v. 5.42.2

While *sometimes* `no_js` was used for visitors without js (for example
disabling it on your browser) it was also used for some pages that were
disabled to JS capable browsers, including the 404 page.
Even worse, sometimes it was used on pages that *had* Javascript, such
as our `/activate-account` route. It has been renamed to `no_ember` to
indicate what it really is, a layout for the site that doesn't load our
Ember.js application.
Added the site setting long_polling_base_url , this allows you
to farm long polling to a different server.
This setting is very important if a CDN is serving dynamic content.
