Sam 379384ae1e FIX: never block /srv/status which is used for health checks

OsamaSayegh decf1f27cf FEATURE: Groundwork for user-selectable theme components
* Phase 0 for user-selectable theme components

- Drops `key` column from the `themes` table
- Drops `theme_key` column from the `user_options` table
- Adds `theme_ids` (array of ints default []) column to the `user_options` table and migrates data from `theme_key` to the new column.
- Removes the `default_theme_key` site setting and adds `default_theme_id` instead.
- Replaces `theme_key` cookie with a new one called `theme_ids`
- no longer need Theme.settings_for_client

Sam e72fd7ae4e FIX: move crawler blocking into anon cache
This refinement of previous fix moves the crawler blocking into

Sam ded84a4b58 PERF: improve performance once logged in rate limiter hits
If "logged in" is being forced anonymous on certain routes, trigger
the protection for any requests that spend 50ms queueing

This means that ...

1. You need to trip it by having 3 requests take longer than 1 second in 10 second interval
2. Once tripped, if your route is still spending 50m queueuing it will continue to be protected

This means that site will continue to function with almost no delays while it is scaling up to handle the new load
2018-04-23 11:55:25 +10:00
Sam 4810ce3607 correct regression 2018-04-18 21:04:08 +10:00
Sam 59cd7894d9 FEATURE: if site is under extreme load show anon view
If a particular path is being hit extremely hard by logged on users,
revert to anonymous cached view.

This will only come into effect if 3 requests queue for longer than 2 seconds
on a *single* path.

This can happen if a URL is shared with the entire forum base and everyone
is logged on

Sam a3e8c3cd7b FEATURE: Native theme support
This feature introduces the concept of themes. Themes are an evolution
of site customizations.

Themes introduce two very big conceptual changes:

- A theme may include other "child themes", children can include grand
children and so on.

- A theme may specify a color scheme

The change does away with the idea of "enabled" color schemes.

It also adds a bunch of big niceties like

- You can source a theme from a git repo

- History for themes is much improved

- You can only have a single enabled theme. Themes can be selected by
    users, if you opt for it.

On a technical level this change comes with a whole bunch of goodies

- All CSS is now compiled using a custom pipeline that uses libsass
    see /lib/stylesheet

- There is a single pipeline for css compilation (in the past we used
    one for customizations and another one for the rest of the app

- The stylesheet pipeline is now divorced of sprockets, there is no
   reliance on sprockets for CSS bundling

- CSS is generated with source maps everywhere (including themes) this
    makes debugging much easier

- Our "live reloader" is smarter and avoid a flash of unstyled content
   we run a file watcher in "puma" in dev so you no longer need to run
   rake autospec to watch for CSS changes
