## Problem
The RequestContext::span shouldn't live for the entire postgres
connection, only the handshake.
## Summary of changes
* Slight refactor to the RequestContext to discard the span upon
handshake completion.
* Make sure the temporary future for the handshake is dropped (not bound
to a variable)
* Runs our nightly fmt script
## Problem
Any errors from these async blocks are unconditionally logged at error
level
even though we already handle such errors based on context.
## Summary of changes
* Log raw errors from creating and executing cplane requests at debug
level.
* Inline macro calls to retain the correct callsite.
## Problem
The vast majority of the error/warn logs from cplane are about time or
data transfer quotas exceeded or endpoint-not-found errors and not
operational errors in proxy or cplane.
## Summary of changes
* Demote cplane error replies to info level.
* Raise other errors from warn back to error.
I found the rightward drift of the `renew_jwks` function hard to review.
This PR splits out some major logic and uses early returns to make the
happy path more linear.
Fixes the masking for the CancelKeyData display format. Due to negative
i32 cast to u64, the top-bits all had `0xffffffff` prefix. On the
bitwise-or that followed, these took priority.
This PR also compresses 3 logs during sql-over-http into 1 log with
durations as label fields, as prior discussed.
## Problem
```
curl -H "Neon-Connection-String: postgresql://neondb_owner:PASSWORD@ep-autumn-rain-a58lubg0.us-east-2.aws.neon.tech/neondb?sslmode=require" https://ep-autumn-rain-a58lubg0.us-east-2.aws.neon.tech/sql -d '{"query":"SELECT 1","params":[]}'
```
For such a query, I also need to send `params`. Do I really need it?
## Summary of changes
I've marked `params` as optional
Follow up to #9803
See https://github.com/neondatabase/cloud/issues/14378
In collaboration with @cloneable and @awarus, we sifted through logs and
simply demoted some logs to debug. This is not at all finished and there
are more logs to review, but we ran out of time in the session we
organised. In any slightly more nuanced cases, we didn't touch the log,
instead leaving a TODO comment.
I've also slightly refactored the sql-over-http body read/length reject
code. I can split that into a separate PR. It just felt natural after I
switched to `read_body_with_limit` as we discussed during the meet.
## Problem
It is called context/ctx everywhere and the Monitoring suffix needlessly
confuses with proper monitoring code.
## Summary of changes
* Rename RequestMonitoring to RequestContext
* Rename RequestMonitoringInner to RequestContextInner

Currently, local_proxy will write an error log if it doesn't find the
config file. This is expected for startup, so it's just noise. It is an
error if we do receive an explicit SIGHUP though.
I've also demoted the build info logs to be debug level. We don't need
them in the compute image since we have other ways to determine what
code is running.
Lastly, I've demoted SIGHUP signal handling from warn to info, since
it's not really a warning event.

Compiling with nightly rust compiler, I'm getting a lot of errors like

They are caused by the `rust_2024_compatibility` lint option.
When we actually switch to the 2024 edition, it makes sense to go
through all these and check that the drop order changes don't break
anything, but in the meanwhile, there's no easy way to avoid these
errors. Disable it, to allow compiling with nightly again.

While setting up some tests, I noticed that we didn't support keycloak.
They make use of encryption JWKs as well as signature ones. Our current
jwks crate does not support parsing encryption keys which caused the
entire jwk set to fail to parse. Switching to lazy parsing fixes this.
Also while setting up tests, I couldn't use localhost jwks server as we
require HTTPS and we were using webpki so it was impossible to add a
custom CA. Enabling native roots addresses this possibility.
I saw some of our current e2e tests against our custom JWKS in s3 were
taking a while to fetch. I've added a timeout + retries to address this.
I think I meant to make these changes over 6 months ago. alas, better
late than never.
1. should_reject doesn't eagerly intern the endpoint string
2. Rate limiter uses a std Mutex instead of a tokio Mutex.
3. Recently I introduced a `-local-proxy` endpoint suffix. I forgot to
add this to normalize.
4. Random but a small cleanup making the ControlPlaneEvent deser
directly to the interned strings.
The overall idea of the PR is to rename a few types to make their
purpose more clear, reduce abstraction where not needed, and move types
to to more better suited modules.
The PROXY Protocol V2 offers a "command" concept. It can be of two
different values. "Local" and "Proxy". The spec suggests that "Local" be
used for health-checks. We can thus use this to silence logging for such
health checks such as those from NLB.
This additionally refactors the flow to be a bit more type-safe, self
documenting and using zerocopy deser.
Unify client, EndpointConnPool and DbUserConnPool for remote and local
conn.
- Use new ClientDataEnum for additional client data.
- Add ClientInnerCommon client structure.
- Remove Client and EndpointConnPool code from local_conn_pool.rs
* Also rename `AuthFailed` variant to `PasswordFailed`.
* Before this all JWT errors end up in `AuthError::AuthFailed()`,
expects a username and also causes cache invalidation.
AWS/azure private link shares extra information in the "TLV" values of
the proxy protocol v2 header. This code doesn't action on it, but it
parses it as appropriate.
It seems the ecosystem is not so keen on moving to aws-lc-rs as it's
build setup is more complicated than ring (requiring cmake).
Eventually I expect the ecosystem should pivot to
https://github.com/ctz/graviola/tree/main/rustls-graviola as it
stabilises (it has a very simply build step and license), but for now
let's try not have a headache of juggling two crypto libs.
I also noticed that tonic will just fail with tls without a default
provider, so I added some defensive code for that.
In the base64 payload of an aws cognito jwt, I saw the following:
```
"iss":"https:\/\/cognito-idp.us-west-2.amazonaws.com\/us-west-2_redacted"
```
issuers are supposed to be URLs, and URLs are always valid un-escaped
JSON. However, `\/` is a valid escape character so what AWS is doing is
technically correct... sigh...
This PR refactors the test suite and adds a new regression test for
cognito.
Follow up on #9344. We want to install the extension automatically. We
didn't want to couple the extension into compute_ctl so instead
local_proxy is the one to issue requests specific to the extension.
depends on #9344 and #9395
The forever ongoing effort of juggling multiple versions of rustls :3
now with new crypto library aws-lc.
Because of dependencies, it is currently impossible to not have both
ring and aws-lc in the dep tree, therefore our only options are not
updating rustls or having both crypto backends enabled...
According to benchmarks run by the rustls maintainer, aws-lc is faster
than ring in some cases too <https://jbp.io/graviola/>, so it's not
without its upsides,
First PR for #9284
Start unification of the client and connection pool interfaces:
- Exclude the 'global_connections_count' out from the get_conn_entry()
- Move remote connection pools to the conn_pool_lib as a reference
- Unify clients among all the conn pools
## Problem
We were seeing timeouts on migrations in this test.
The test unfortunately tends to saturate local storage, which is shared
between the pageservers and the control plane database, which makes the
test kind of unrealistic. We will also want to increase the scale of
this test, so it's worth fixing that.
## Summary of changes
- Instead of randomly creating timelines at the same time as the other
background operations, explicitly identify a subset of tenant which will
have timelines, and create them at the start. This avoids pageservers
putting a lot of load on the test node during the main body of the test.
- Adjust the tenants created to create some number of 8 shard tenants
and the rest 1 shard tenants, instead of just creating a lot of 2 shard
tenants.
- Use archival_config to exercise tenant-mutating operations, instead of
using timeline creation for this.
- Adjust reconcile_until_idle calls to avoid waiting 5 seconds between
calls, which causes timelines with large shard count tenants.
- Fix a pageserver bug where calls to archival_config during activation
get 404
removes the ConsoleRedirect backend from the main auth::Backends enum,
copy-paste the existing crate::proxy::task_main structure to use the
ConsoleRedirectBackend exclusively.
This makes the logic a bit simpler at the cost of some fairly trivial
code duplication.
preliminary for #9270
The auth::Backend didn't need to be in the mega ProxyConfig object, so I
split it off and passed it manually in the few places it was necessary.
I've also refined some of the uses of config I saw while doing this
small refactor.
I've also followed the trend and make the console redirect backend it's
own struct, same as LocalBackend and ControlPlaneBackend.
## Problem
Fixes#8340
## Summary of changes
Introduced ErrorKind::quota to handle quota-related errors
