Summary:
Ref T4571. Write more of the missing documentation sections and clarify a few things.
Since the "replicating master" check needs a special permission, imposes a performance penalty, is probably very difficult to misconfigure, and likely not a big deal anyway, just drop the idea of trying to automatically detect + prevent it. We still show if it's an issue on the status page, provided we have permission to check.
When you don't have any cluster databases configured, never stop trying to connect to the default master database. We might want to do this eventually as load reduction, but just don't muddy the waters too much for now while things stabilize.
Test Plan:
- Tested functionality in cluster, non-cluster, and degraded-cluster modes.
- Used status console to monitor a health check cycle.
- Read docs.

Summary:
Ref T4571. When a database goes down briefly, we fall back to replicas.
However, this fallback is slow (not good for users) and keeps sending a lot of traffic to the master (might be bad if the root cause is load-related).
Keep track of recent connections and fully degrade into "severed" mode if we see a sequence of failures over a reasonable period of time. In this mode, we send much less traffic to the master (faster for users; less load for the database).
We do send a little bit of traffic still, and if the master recovers we'll recover back into normal mode seeing several connections in a row succeed.
This is similar to what most load balancers do when pulling web servers in and out of pools.
For now, the specific numbers are:
- We do at most one health check every 3 seconds.
- If 5 checks in a row fail or succeed, we sever or un-sever the database (so it takes about 15 seconds to switch modes).
- If the database is currently marked unhealthy, we reduce timeouts and retries when connecting to it.
Test Plan:
- Configured a bad `master`.
- Browsed around for a bit, initially saw "unrechable master" errors.
- After about 15 seconds, saw "major interruption" errors instead.
- Fixed the config for `master`.
- Browsed around for a while longer.
- After about 15 seconds, things recovered.
- Used "Cluster Databases" console to keep an eye on health checks: it now shows how many recent health checks were good:

Summary:
Ref T4571. If we fail to connect to the master, automatically try to degrade into a temporary read-only mode ("UNREACHABLE") for the remainder of the request, if possible.
If the request was something like "load the homepage", that'll work fine. If it was something like "submit a comment", there's nothing we can do and we just have to fail.
Detecting this condition imposes a performance penalty: every request checks the connection and gives the database a long time to respond, since we don't want to drop writes unless we have to. So the degraded mode works, but it's really slow, and may perpetuate the problem if the root issue is load-related.
This lays the groundwork for improving this case by degrading futher into a "SEVERED" mode which will persist across requests. In the future, if several requests in a short period of time fail, we'll sever the database host and refuse to try to connect to it for a little while, connecting directly to replicas instead (basically, we're "health checking" the master, like a load balancer would health check a web application server). This will give us a better (much faster) degraded mode in a major service disruption, and reduce load on the master if the root cause is load-related, giving it a better chance of recovering on its own.
Test Plan:
- Disabled master in config by changing the host/username, got degraded automatically to UNREACAHBLE mode immediately.
- Faked full SEVERED mode, requests hit replicas and put me in the mode properly.
- Made stuff work, hit some good pages.
- Hit some non-cluster pages.

However, this flickers a lot in Safari. We might be able to cache this, but we really shouldn't, since the preview URI isn't a legitimately stable/permanent one.
Instead, do a (cheap) server-side check to see if the preview already exists. If it does, return a direct URI. This gives us a stable thumbnail in Safari.

The URI will stop working once any attached object changes its view policy, or the file view policy itself changes.
Files with `canCDN` (totally public data like profile images, CSS, JS, etc) use "cache-control: public" so they can be CDN'd.
Files without `canCDN` use "cache-control: private" so they won't be cached by the CDN. They could still be cached by a misbehaving local cache, but if you don't want your users seeing one anothers' secret files you should configure your local network properly.
Our "Cache-Control" headers were also from 1999 or something, update them to be more modern/sane. I can't find any evidence that any browser has done the wrong thing with this simpler ruleset in the last ~10 years.

- the view policy or space for an object the file is attached to changes (and the file policy is not "public" or "all users").
This basically means that when you change the visibility of a task, any old URLs for attached files stop working and new ones are implicitly generated.

Summary:
Ref T7303. Currently, our handling of "scope" is fairly rigid and adheres to the spec, but some of these behaviors don't make much sense in practice.
Soften some behaviors and make them more flexible:
**Soft Failure on Unknown Permissions**: If a client asks for a permission we don't know about, just warn that we don't recognize it instead of fataling. In particular, I plan to make `offline_access` and `whoami` implicit. Older clients that request these permissions will still work fine as long as we don't hard-fatal.
**Move `user.whoami` to ALWAYS scope**: Make `whoami` a default permission. We've already done this, in effect; this just formalizes it.
**Tokens no longer expire**: Make `offline_access` (infinite-duration tokens) a default permission. I think the OAuth model doesn't map well to reality. It is common for other providers to issue "temporary" tokens with a duration of multiple years, and the refesh workflow is sort of silly. We can add a "temporary" scope later if we need temporary tokens.
This flow was potentially extra silly with the "log out of Phacility" use case, where we might need to have you log in again before we could log you out, which is bizarre and senseless. Avoid this nonsense.
**Move away from granular permissions**: Users currently get to pick-and-choose which permissions they grant, but this likely rarely/never works in practice and is fairly hostile since applications can't communicate which permissions they need. Applications which can actually operate with only some subset of permissions can make separate requests (e.g., when you activate "cool feature X", it asks for X permission). I think applications that do this are rare; pretty much everything just asks for tons of permissions and everyone grants them.
Making this all-or-nothing is better for well-behaved applications and better for users. It's also slightly better for overzealous applications that ask for more than they need, but whatever. Users can make an informed decision, hopefully, and I plan to let administrators force applications to a subset of permissions once we introduce meaningful scopes.
Test Plan:
- Generated tokens.
- Used tokens.
- Authorized an instance.
- Faked some bogus scopes, got clean authorization.
