5e37350561 Refactor and unit test authentication code paths (closes #4736)
The bulk of changes here is some shifting of code around and a little
parameterizing of functions for easier testing.

Also: comments, some renaming for clarity/less-chance-for-misue.

d747bc1148 Tighten up handling of admin secret, more docs
Store the admin secret only as a hash to prevent leaking the secret
inadvertently, and to prevent timing attacks on the secret.

NOTE: best practice for stored user passwords is a function with a
tunable cost like bcrypt, but our threat model is quite different (even
if we thought we could reasonably protect the secret from an attacker
who could read arbitrary regions of memory), and bcrypt is far too slow
(by design) to perform on each request. We'd have to rely on our
(technically savvy) users to choose high entropy passwords in any case.

ff62d5e0bf Migrate to GHC 8.10, upgrade dependencies. Closes #4517
This also seems to squash a stubborn space leak we see with
subscriptions (linking to canonical #3388 for reference).

This may also fix some of the "Unexpected exception" websockets
exceptions we are now surfacing (see e.g. #4344)

Also: dev.sh: fix hpc reporting

Initial work on this done by Vamshi.

server: add support for webhook connection expiration (#4196)
* add expiry time to webhook user info

This also adds an optional message to webhook errors: if we fail to
parse an expiry time, we will log a warning with the parse error.

* refactored Auth

This change had one main goal: put in common all expiry time
extraction code between the JWT and WebHook parts of the
code. Furthermore, this change also moves all WebHook specific code to
its own module, similarly to what is done for JWT.

* Remove dependency on string-conversions in favor of text-conversions

string-conversions silently uses UTF8 instead of being explicit about
it, and it uses lenientDecode when decoding ByteStrings when it’s
usually better to reject invalid UTF8 input outright. text-conversions
solves both those problems.

Use AssertNF for leak prophylaxis when doing mutable writes. Closes #3937 (#4097)
Writing to a mutable var is a particularly potent source of leaks since
it mostly defeats GHC's analysis. Here we add assertions to all mutable
writes, and fix a couple spots where we wrote some thunks to a mutable
var (compiled with -O2).

Some of these thunks were probably benign, but others looked liked they
might be retaining big args. Didn't do much analysis, just fixed.

Actually pretty happy with how easy this was to use and as a diagnostic,
once I sorted out some issues. We should consider using it elsewhere,
and maybe extending so that we can use it with tests, enable when
`-fenable-assertsions` etc.

Relates #3388

Also simplified codepaths that use `AcceptWith`, which has unnecessary
`Maybe` fields.

More robust forking, exception safety. Closes #3768 (#3860)
This is the result of a general audit of how we fork threads, with a
detour into how we're using mutable state especially in websocket
codepaths, making more robust to async exceptions and exceptions
resulting from bugs.

Some highlights:
- use a wrapper around 'immortal' so threads that die due to bugs are
  restarted, and log the error
- use 'withAsync' some places
- use bracket a few places where we might break invariants
- log some codepaths that represent bugs
- export UnstructuredLog for ad hoc logging (the alternative is we
  continue not logging useful stuff)

I had to timebox this. There are a few TODOs I didn't want to address.
And we'll wait until this is merged to attempt #3705 for
Control.Concurrent.Extended

58ef316118 Add request timings and count histograms to telemetry. Closes #3552
We upload a set of accumulating timers and counters to track service
time for different types of operations, across several dimensions (e.g.
did we hit the plan cache, was a remote involved, etc.)

Also...

Standardize on DiffTime as a standard duration type, and try to use it
consistently.

See discussion here:
https://github.com/hasura/graphql-engine/pull/3584#pullrequestreview-340679369

It should be possible to overwrite that module so the new threadDelay
sticks per the pattern in #3705 blocked on #3558

Rename the Control.Concurrent.Extended.threadDelay to `sleep` since a
naive use with a literal argument would be very bad!

We catch a bug in 'computeTimeDiff'.

Add convenient 'Read' instances to the time unit utility types. Make
'Second' a newtype to support this.

199a24d050 add support for multiple domains in cors config (close #1436) (#1536)
Support for multiple domains (as CSV) in the `--cors-domain` flag and `HASURA_GRAPHQL_CORS_DOMAIN` env var.

Following are all valid configurations (must include scheme and optional port):
```shell
HASURA_GRAPHQL_CORS_DOMAIN="https://*.foo.bar.com:8080"
HASURA_GRAPHQL_CORS_DOMAIN="https://*.foo.bar.com, http://*.localhost, https://example.com"
HASURA_GRAPHQL_CORS_DOMAIN="*"
HASURA_GRAPHQL_CORS_DOMAIN="http://example.com, http://*.localhost, http://localhost:3000, https://*.foo.bar.com, https://foo.bar.com"
```

**Note**: top-level domains are not considered as part of wildcard domains. You have to add them separately. E.g - `https://*.foo.com` doesn't include `https://foo.com`.

The default (if the flag or env var is not specified) is `*`. Which means CORS headers are sent for all domains.

Optional jwk_url parameter is taken. The published JWK set under that URL should be in standard JWK format (tools.ietf.org/html/rfc7517#section-4.8).

b2f88ff28a add support for jwt authorization (close #186) (#255)
The API:
1. HGE has `--jwt-secret` flag or `HASURA_GRAPHQL_JWT_SECRET` env var. The value of which is a JSON.

2. The structure of this JSON is: `{"type": "<standard-JWT-algorithms>", "key": "<the-key>"}`
`type` : Standard JWT algos : `HS256`, `RS256`, `RS512` etc. (see jwt.io).
`key`:
  i. Incase of symmetric key, the key as it is.
  ii. Incase of asymmetric keys, only the public key, in a PEM encoded string or as a X509 certificate.

3. The claims in the JWT token must contain the following:
  i. `x-hasura-default-role` field: default role of that user
  ii. `x-hasura-allowed-roles` : A list of allowed roles for the user. The default role is overriden by `x-hasura-role` header.

4. The claims in the JWT token,  can have other `x-hasura-*` fields where their values can only be strings.

5. The JWT tokens are sent as `Authorization: Bearer <token>` headers.

---
To test:
1. Generate a shared secret (for HMAC-SHA256) or RSA key pair.
2. Goto https://jwt.io/ , add the keys
3. Edit the claims to have `x-hasura-role` (mandatory) and other `x-hasura-*` fields. Add permissions related to the claims to test permissions.
4. Start HGE with `--jwt-secret` flag or `HASURA_GRAPHQL_JWT_SECRET` env var, which takes a JSON string: `{"type": "HS256", "key": "mylongsharedsecret"}` or `{"type":"RS256", "key": "<PEM-encoded-public-key>"}`
5. Copy the JWT token from jwt.io and use it in the `Authorization: Bearer <token>` header.
