Sam 8b7a2d1cb7 FEATURE: add setting to bypass sending redis CLIENT commands
Some cloud providers (Google Memorystore) do not support any CLIENT commands

By setting :id to nil in the redis config hash we can avoid these commands.

This adds a special global setting GCE users can enable:
`DISCOURSE_REDIS_SKIP_CLIENT_COMMANDS = true`

Sam 8f35fd4595 FEATURE: remove global settings for redis sentinels
This global setting is never used, configuring Discourse with sentinel is
unsupported.

Sam 70269c7c97 FEATURE: tighter limits on per cluster post rebakes
We have the periodical job that regularly will rebake old posts. This is
used to trickle in update to cooked markdown. The problem is that each rebake
can issue multiple background jobs (post process and pull hotlinked images)

Previously we had no per-cluster limit so cluster running 100s of sites could
flood the sidekiq queue with rebake related jobs.

New system introduces a hard limit of 300 rebakes per 15 minutes across a
cluster to ensure the sidekiq job is not dominated by this.

We also reduced `rebake_old_posts_count` to 80, which is a safer default.

Sam 87fabdc2f3 FIX: correct pool reaper
This removes a freedom patch and replaces with a custom reaper thread
it also captures an issue where reaper would fail when connections where
empty

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

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

Guo Xiang Tan a89f3160a5 Add new config to ensure backup/restore connects to PG directly.
* In `pg_dump` 10.3+ and 9.5.12+, in
  it does a `SELECT pg_catalog.set_config('search_path', '', false)`
  which changes the state of the current connection. This is known
  to be problematic with Pgbouncer which reuses connections. As such,
  we'll always try to connect directly to PG directly during
  the backup/restore process.

Sam 70bb2aa426 FEATURE: allow specifying s3 config via globals
This refactors handling of s3 so it can be specified via GlobalSetting

This means that in a multisite environment you can configure s3 uploads
without actual sites knowing credentials in s3

It is a critical setting for situations where assets are mirrored to s3.

Sam c106ca6778 FEATURE: fallback asset path for multi host setups 2017-03-20 15:59:17 -04:00
Sam ff49f72ad9 FEATURE: per client user tokens
Revamped system for managing authentication tokens.

- Every user has 1 token per client (web browser)
- Tokens are rotated every 10 minutes

New system migrates the old tokens to "legacy" tokens,
so users still remain logged on.

Also introduces weekly job to expire old auth tokens.
