f047b7dd17 server: update the jwt refresh thread to poll
## Description
This PR updates the JWK refresh thread to poll every second instead of the previous behaviour where the thread used to sleep based on the expiry time in `Cache-Control`/`Expires` response headers.

## Motivation
As a part of dynamically updating environment variables on cloud without restart the user projects, we want to implement a mechanism which makes HGE aware of any changes in the user configuration by updating a shared variable data type which can be accessed by relevant threads/core functionality before their execution.

The above updates requires us to make the threads polling in nature such that before executing their code, any change in the user config is captured and the appropriate behaviour is channelised. In the case of JWK updating thread, the thread used to sleep for the time as mentioned in the `Cache-Control` or `Expires` headers which make the thread unware of any new changes in the user config in that period of time, hence requiring a restart to propogate the new changes.

To solve this problem we have now updated the JWK update thread to poll every second for change in `AuthMode`(from a shared variable in subsequent changes to implement the dynamic env var update feature) and update the JWK accordingly such that it does not use any stale configurations and works without HGE restart.

### Related Issues
https://hasurahq.atlassian.net/browse/GS-300

### Solution and Design
- We store the expiry time in the `JWTCtx`
- On every poll check whether the current time exceeds the expiry time, in which case we call the JWK url to fetch the new JWK and expiry.

4d6604ba08 server: event trigger codecs
Codecs for event triggers, including webhook transforms. These are not hooked into the higher-up table metadata codec yet because some backend implementations implement event triggers with `error` which causes an error when codecs are evaluated. I plan to follow up with another PR to resolve that.

6451d9c9ce server: refactor Hasura.Server.Compression for clarity/correctness
context: This is  foundation work, before we change how the server chooses to compress or not
part of effort: #5518

-----

Prior to this change it was difficult to understand how the functionality in this module related to the semantics of Accept-Encoding. We also didn't correctly handle directives with qvalues.

After this change certain technical infelicities are called out without modifying the behavior of the server; for instance we continue to fall back to identity (no compression) in the case where technically we're supposed to return 406, and we also  continue to treat `*` conservatively as meaning “use no compression”.

The only external change here is `gzip;q=x.y` now results in a zipped response.

698190894f server: use kriti template to generate query param from list
## Description ✍️
This PR adds support to generate query params directly using a kriti template which can be used to flatten a list of parameter arguments as well.

### Changes in the Metadata API
Earlier the `query_params` key inside `request_transform` used to take in an object of key/value pairs where the `key` represents the query parameter name and `value` points to the value of the parameter or a kriti template which could be resolved to the value.

With this PR, we provide the user with more freedom to generate the complete query string using kriti template. The  `query_params` can now take in a string as well which will be a kriti template. This new change needs to be incorporated on the console and CLI metadata import/export as well.
- [x] CLI: Compatible, no changes required
- [ ] Console

## Changelog ✍️

__Component__ : server

__Type__: feature

__Product__: community-edition

### Short Changelog

use kriti template to generate query param from list of arguments

### Related Issues ✍
https://hasurahq.atlassian.net/browse/GS-243

### Solution and Design ✍
We use a kriti template to generate the complete query parameter string.

| Query Template | Output |
|---|---|
| `{{ concat ([concat({{ range _, x := [\"apple\", \"banana\"] }} \"tags={{x}}&\" {{ end }}), \"flag=smthng\"]) }}`| `tags=apple&tags=banana&flag=smthng`  |
| `{{ concat ([\"tags=\", concat({{ range _, x := $body.input }} \"{{x}},\" {{ end }})]) }}` | `tags=apple%2Cbanana%2C` |

### Steps to test and verify ✍
- start HGE and make the following request to `http://localhost:8080/v1/metadata`:
```json
{
    "type": "test_webhook_transform",
    "args": {
        "webhook_url": "http://localhost:3000",
        "body": {
            "action": {
                "name": "actionName"
            },
            "input": ["apple", "banana"]
        },
        "request_transform": {
            "version": 2,
            "url": "{{$base_url}}",
            "query_params": "{{ concat ([concat({{ range _, x := $body.input }} \"tags={{x}}&\" {{ end }}), \"flag=smthng\"]) }}",
            "template_engine": "Kriti"
        }
    }
}
```
- you should receive the following as output:
```json
{
    "body": {
        "action": {
            "name": "actionName"
        },
        "input": [
            "apple",
            "banana"
        ]
    },
    "headers": [],
    "method": "GET",
    "webhook_url": "http://localhost:3000?tags=apple&tags=banana&flag=smthng"
}
```

80c977da85 server: Split the integration tests out into their own directories.
We currently have a fairly intricate way of running our PostgreSQL and MSSQL integration tests (not the API tests). By splitting them out, we can simplify this a lot. Most prominently, we can rely on Cabal to be our argument parser instead of writing our own.

We can also simplify how they're run in CI. They are currently (weirdly) run alongside the Python integration tests. This breaks them out into their own jobs for better visibility, and to avoid conflating the two.

The changes are as follows:

- The "unit" tests that rely on a running PostgreSQL database are extracted out to a new test directory so they can be run separately.
  - Most of the `Main` module comes with them.
  - We now refer to these as "integration" tests instead.
- Likewise for the "unit" tests that rely on a running MS SQL Server database. These are a little simpler and we can use `hspec-discover`, with a `SpecHook` to extract the connection string from an environment variable.
  - Henceforth, these are the MS SQL Server integration tests.
- New CI jobs have been added for each of these.
  - There wasn't actually a job for the MS SQL Server integration tests. It's pretty amazing they still run well.
- The "haskell-tests" CI job, which used to run the PostgreSQL integration tests, has been removed.
- The makefiles and contributing guide have been updated to run these.

42e5205eb5 server: reduce schema contexts to the bare minimum
### Description

This monster of a PR took way too long. As the title suggests, it reduces the schema context carried in the readers to the very strict minimum. In practice, that means that to build a source, we only require:
  - the global `SchemaContext`
  - the global `SchemaOptions` (soon to be renamed `SchemaSourceOptions`)
  - that source's `SourceInfo`

Furthermore, _we no longer carry "default" customization options throughout the schema_. All customization information is extracted from the `SourceInfo`, when required. This prevents an entire category of bugs we had previously encountered, such as parts of the code using uninitialized / unupdated customization info.

In turn, this meant that we could remove the explicit threading of the `SourceInfo` throughout the schema, since it is now always available through the reader context.

Finally, this meant making a few adjustments to relay and actions as well, such as the introduction of a new separate "context" for actions, and a change to how we create some of the action-specific postgres scalar parsers.

I'll highlight with review comments the areas of interest.

6ac67a5566 Allow collecting metadata dependencies and inconsistencies separately
`CollectedInfo` was just an awkward sum type. By using an explicit `Either` instead, we can guarantee at the type level that certain methods only write inconsistencies, or only write dependencies. This is useful, because if we can guarantee that no dependencies are written, then we don't need to run `resolveDependencies` on that part of the Metadata. In other words, we can keep it out of `BuildOutputs`, which greatly benefits performance - see e.g. hasura/graphql-engine-mono#6613.

342391f39d Upgrade Ormolu to v0.5.
This upgrades the version of Ormolu required by the HGE repository to v0.5.0.1, and reformats all code accordingly.

Ormolu v0.5 reformats code that uses infix operators. This is mostly useful, adding newlines and indentation to make it clear which operators are applied first, but in some cases, it's unpleasant. To make this easier on the eyes, I had to do the following:

* Add a few fixity declarations (search for `infix`)
* Add parentheses to make precedence clear, allowing Ormolu to keep everything on one line
* Rename `relevantEq` to `(==~)` in #6651 and set it to `infix 4`
* Add a few _.ormolu_ files (thanks to @hallettj for helping me get started), mostly for Autodocodec operators that don't have explicit fixity declarations

In general, I think these changes are quite reasonable. They mostly affect indentation.

9921823915 GDC-189 custom aggregations
>

## Description
->

This PR allows DC agents to define custom aggregate functions for their scalar types.

### Related Issues
->

GDC-189

### Solution and Design
>

We added a new property `aggregate_functions` to the scalar types capabilities. This allows the agent author to specify a set of aggregate functions supported by each scalar type, along with the function's result type.

During GraphQL schema generation, the custom aggregate functions are available via a new method `getCustomAggregateOperators` on the `Backend` type class.
Custom functions are merged with the builtin aggregate functions when building GraphQL schemas for table aggregate fields and for `order_by` operators on array relations.

### Steps to test and verify
>

• Codec tests for aggregate function capabilities have been added to the unit tests.
• Some custom aggregate operators have been added to the reference agent and are used in a new test in `api-tests`.

c3afa0fdd7 Install and use ODBC Driver 18 for SQL Server (msodbcsql18).
This installs the ODBC Driver 18 for SQL Server in all our shipped Docker images, and update our tests and documentation accordingly.

This version supports arm64, and therefore can run natively (or via Docker) on macOS on aarch64.

`msodbcsql17` is still installed in production-targeted Docker images so that users do not _have_ to migrate to the new driver.

Nix expressions are packaged for the new driver, as it is not yet available in nixpkgs.

In this version, [the default encryption setting was changed from "no" to "yes"](https://techcommunity.microsoft.com/t5/sql-server-blog/odbc-driver-18-0-for-sql-server-released/ba-p/3169228). In addition, "mandatory" and "optional" were added as synonyms for "yes" and "no" respectively.

I have therefore modified all connection strings in tests to specify `Encrypt=optional` (and changed some from `Encrypt=no`). I chose "optional" rather than "no" because I feel it's more honest; these connection strings will work with or without an encrypted connection.

a01d1188f2 scaffolding for remote-schemas module
The main aim of the PR is:

1. To set up a module structure for 'remote-schemas' package.
2. Move parts by the remote schema codebase into the new module structure to validate it.

## Notes to the reviewer

Why a PR with large-ish diff?

1. We've been making progress on the MM project but we don't yet know long it is going to take us to get to the first milestone. To understand this better, we need to figure out the unknowns as soon as possible. Hence I've taken a stab at the first two items in the [end-state](https://gist.github.com/0x777/ca2bdc4284d21c3eec153b51dea255c9) document to figure out the unknowns. Unsurprisingly, there are a bunch of issues that we haven't discussed earlier. These are documented in the 'open questions' section.

1. The diff is large but that is only code moved around and I've added a section that documents how things are moved. In addition, there are fair number of PR comments to help with the review process.

## Changes in the PR

### Module structure

Sets up the module structure as follows:

```
Hasura/
  RemoteSchema/
    Metadata/
      Types.hs
    SchemaCache/
      Types.hs
      Permission.hs
      RemoteRelationship.hs
      Build.hs
    MetadataAPI/
      Types.hs
      Execute.hs
```

### 1. Types representing metadata are moved

Types that capture metadata information (currently scattered across several RQL modules) are moved into `Hasura.RemoteSchema.Metadata.Types`.

- This new module only depends on very 'core' modules such as
  `Hasura.Session` for the notion of roles and `Hasura.Incremental` for `Cacheable` typeclass.

- The requirement on database modules is avoided by generalizing the remote schemas metadata to accept an arbitrary 'r' for a remote relationship
  definition.

### 2. SchemaCache related types and build logic have been moved

Types that represent remote schemas information in SchemaCache are moved into `Hasura.RemoteSchema.SchemaCache.Types`.

Similar to `H.RS.Metadata.Types`, this module depends on 'core' modules except for `Hasura.GraphQL.Parser.Variable`. It has something to do with remote relationships but I haven't spent time looking into it. The validation of 'remote relationships to remote schema' is also something that needs to be looked at.

Rips out the logic that builds remote schema's SchemaCache information from the monolithic `buildSchemaCacheRule` and moves it into `Hasura.RemoteSchema.SchemaCache.Build`. Further, the `.SchemaCache.Permission` and `.SchemaCache.RemoteRelationship` have been created from existing modules that capture schema cache building logic for those two components.

This was a fair amount of work. On main, currently remote schema's SchemaCache information is built in two phases - in the first phase, 'permissions' and 'remote relationships' are ignored and in the second phase they are filled in.

While remote relationships can only be resolved after partially resolving sources and other remote schemas, the same isn't true for permissions. Further, most of the work that is done to resolve remote relationships can be moved to the first phase so that the second phase can be a very simple traversal.

This is the approach that was taken - resolve permissions and as much as remote relationships information in the first phase.

### 3. Metadata APIs related types and build logic have been moved

The types that represent remote schema related metadata APIs and the execution logic have been moved to `Hasura.RemoteSchema.MetadataAPI.Types` and `.Execute` modules respectively.

## Open questions:

1. `Hasura.RemoteSchema.Metadata.Types` is so called because I was hoping that all of the metadata related APIs of remote schema can be brought in at `Hasura.RemoteSchema.Metadata.API`. However, as metadata APIs depended on functions from `SchemaCache` module (see [1](ceba6d6226/server/src-lib/Hasura/RQL/DDL/RemoteSchema.hs (L55)) and [2](ceba6d6226/server/src-lib/Hasura/RQL/DDL/RemoteSchema.hs (L91)), it made more sense to create a separate top-level module for `MetadataAPI`s.

   Maybe we can just have `Hasura.RemoteSchema.Metadata` and get rid of the extra nesting or have `Hasura.RemoteSchema.Metadata.{Core,Permission,RemoteRelationship}` if we want to break them down further.

1. `buildRemoteSchemas` in `H.RS.SchemaCache.Build` has the following type:

   ```haskell
   buildRemoteSchemas ::
     ( ArrowChoice arr,
       Inc.ArrowDistribute arr,
       ArrowWriter (Seq CollectedInfo) arr,
       Inc.ArrowCache m arr,
       MonadIO m,
       HasHttpManagerM m,
       Inc.Cacheable remoteRelationshipDefinition,
       ToJSON remoteRelationshipDefinition,
       MonadError QErr m
     ) =>
     Env.Environment ->
     ( (Inc.Dependency (HashMap RemoteSchemaName Inc.InvalidationKey), OrderedRoles),
       [RemoteSchemaMetadataG remoteRelationshipDefinition]
     )
       `arr` HashMap RemoteSchemaName (PartiallyResolvedRemoteSchemaCtxG remoteRelationshipDefinition, MetadataObject)
   ```

   Note the dependence on `CollectedInfo` which is defined as

   ```haskell
   data CollectedInfo
     = CIInconsistency InconsistentMetadata
     | CIDependency
         MetadataObject
         -- ^ for error reporting on missing dependencies
         SchemaObjId
         SchemaDependency
     deriving (Eq)
   ```

   this pretty much means that remote schemas is dependent on types from databases, actions, ....

   How do we fix this? Maybe introduce a typeclass such as `ArrowCollectRemoteSchemaDependencies` which is defined in `Hasura.RemoteSchema` and then implemented in graphql-engine?

1. The dependency on `buildSchemaCacheFor` in `.MetadataAPI.Execute` which has the following signature:

   ```haskell
   buildSchemaCacheFor ::
     (QErrM m, CacheRWM m, MetadataM m) =>
     MetadataObjId ->
     MetadataModifier ->
   ```

   This can be easily resolved if we restrict what the metadata APIs are allowed to do. Currently, they operate in an unfettered access to modify SchemaCache (the `CacheRWM` constraint):

   ```haskell
   runAddRemoteSchema ::
     ( QErrM m,
       CacheRWM m,
       MonadIO m,
       HasHttpManagerM m,
       MetadataM m,
       Tracing.MonadTrace m
     ) =>
     Env.Environment ->
     AddRemoteSchemaQuery ->
     m EncJSON
   ```

   This should instead be changed to restrict remote schema APIs to only modify remote schema metadata (but has access to the remote schemas part of the schema cache), this dependency is completely removed.

   ```haskell
   runAddRemoteSchema ::
     ( QErrM m,
       MonadIO m,
       HasHttpManagerM m,
       MonadReader RemoteSchemasSchemaCache m,
       MonadState RemoteSchemaMetadata m,
       Tracing.MonadTrace m
     ) =>
     Env.Environment ->
     AddRemoteSchemaQuery ->
     m RemoteSchemeMetadataObjId
   ```

   The idea is that the core graphql-engine would call these functions and then call
   `buildSchemaCacheFor`.

4c8ea8e865 Import pg-client-hs as PG
Result of executing the following commands:
```shell
# replace "as Q" imports with "as PG" (in retrospect this didn't need a regex)
git grep -lE 'as Q($|[^a-zA-Z])' -- '*.hs' | xargs sed -i -E 's/as Q($|[^a-zA-Z])/as PG\1/'
# replace " Q." with " PG."
git grep -lE ' Q\.' -- '*.hs' | xargs sed -i 's/ Q\./ PG./g'
# replace "(Q." with "(PG."
git grep -lE '\(Q\.' -- '*.hs' | xargs sed -i 's/(Q\./(PG./g'
# ditto, but for [, |, { and !
git grep -lE '\[Q\.' -- '*.hs' | xargs sed -i 's/\[Q\./\[PG./g'
git grep -l '|Q\.' -- '*.hs' | xargs sed -i 's/|Q\./|PG./g'
git grep -l '{Q\.' -- '*.hs' | xargs sed -i 's/{Q\./{PG./g'
git grep -l '!Q\.' -- '*.hs' | xargs sed -i 's/!Q\./!PG./g'
```
(Doing the `grep -l` before the `sed`, instead of `sed` on the entire codebase, reduces the number of `mtime` updates, and so reduces how many times a file gets recompiled while checking intermediate results.)

Finally, I manually removed a broken and unused `Arbitrary` instance in `Hasura.RQL.Network`. (It used an `import Test.QuickCheck.Arbitrary as Q` statement, which was erroneously caught by the first find-replace command.)

After this PR, `Q` is no longer used as an import qualifier. That was not the goal of this PR, but perhaps it's a useful fact for future efforts.

40db3d7eab Resolve source customization at schema cache building time.
### Description

This PR attempts to fix several issues with source customization as it relates to remote relationships. There were several issues regarding casing: at the relationship border, we didn't properly set the target source's case, we didn't have access to the list of supported features to decide whether the feature was allowed or not, and we didn't have access to the global default.

However, all of that information is available when we build the schema cache, as we do resolve the case of some elements such as function names: we can therefore resolve source information at the same time, and simplify both the root of the schema and the remote relationship border.

To do this, this PR introduces a new type, `ResolvedSourceCustomization`, to be used in the Schema Cache, as opposed to the metadata's `SourceCustomization`, following a pattern established by a lot of other types.

### Remaining work and open questions

One major point of confusion: it seems to me that we didn't set the case at all across remote relationships, which would suggest we would use the case of the LHS source across the subset of the RHS one that is accessible through the remote relationship, which would in turn "corrupt" the parser cache and might result in the wrong case being used for that source later on. Is that assesment correct, and was I right to fix it?

Another one is that we seem not to be using the local case of the RHS to name the field in an object relationship; unless I'm mistaken we only use it for array relationships? Is that intentional?

This PR is also missing tests that would show-case the difference, and a changelog entry. To my knowledge, all the tests of this feature are in the python test suite; this could be the opportunity to move them to the hspec suite, but this might be a considerable amount of work?

512a4dbb92 Use a different reader context for sources and remote schemas with new SchemaT monad.
### Description

This PR changes all the schema code to operate in a specific `SchemaT` monad, rather than in an arbitrary `m` monad. `SchemaT` is intended to be used opaquely with `runSourceSchema` and `runRemoteSchema`. The main goal of this is to allow a different reader context per part of the schema: this PR also minimizes the contexts. This means that we no longer require `SchemaOptions` when building remote schemas' schema, and this PR therefore removes a lot of dummy / placeholder values accordingly.

### Performance and stacking

This PR has been through several iterations. #5339 was the original version, that accomplished the same thing by stacking readers on top of the stack at every remote relationship boundary. This raised performance concerns, and @0x777 confirmed with an ad-hoc test that in some extreme cases we could see up to a 10% performance impact. This version, while more verbose, allows us to unstack / re-stack the readers, and avoid that problem. #5517 adds a new benchmark set to be able to automatically measure this on every PR.

### Remaining work

- [x] a comment (or perhaps even a Note?) should be added to `SchemaT`
- [x] we probably want for #5517 to be merged first so that we can confirm the lack of performance penalty

84fd5910b0 server: polymorphic codec for metadata sources
This PR expands the OpenAPI specification generated for metadata to include separate definitions for `SourceMetadata` for each native database type, and for DataConnector.

For the most part the changes add `HasCodec` implementations, and don't modify existing code otherwise.

The generated OpenAPI spec can be used to generate TypeScript definitions that distinguish different source metadata types based on the value of the `kind` properly. There is a problem: because the specified `kind` value for a data connector source is any string, when TypeScript gets a source with a `kind` value of, say, `"postgres"`, it cannot unambiguously determine whether the source is postgres, or a data connector. For example,

```ts
function consumeSourceMetadata(source: SourceMetadata) {
    if (source.kind === "postgres" || source.kind === "pg") {
        // At this point TypeScript infers that `source` is either an instance
        // of `PostgresSourceMetadata`, or `DataconnectorSourceMetadata`. It
        // can't narrow further.
        source
    }
    if (source.kind === "something else") {
        // TypeScript infers that this `source` must be an instance of
        // `DataconnectorSourceMetadata` because `source.kind` does not match
        // any of the other options.
        source
    }
}
```

The simplest way I can think of to fix this would be to add a boolean property to the `SourceMetadata` type along the lines of `isNative` or `isDataConnector`. This could be a field that only exists in serialized data, like the metadata version field. The combination of one of the native database names for `kind`, and a true value for `isNative` would be enough for TypeScript to unambiguously distinguish the source kinds.

But note that in the current state TypeScript is able to reference the short `"pg"` name correctly!

~~Tests are not passing yet due to some discrepancies in DTO serialization vs existing Metadata serialization. I'm working on that.~~

The placeholders that I used for table and function metadata are not compatible with the ordered JSON serialization in use. I think the best solution is to write compatible codecs for those types in another PR. For now I have disabled some DTO tests for this PR.

Here are the generated [OpenAPI spec](https://github.com/hasura/graphql-engine-mono/files/9397333/openapi.tar.gz) based on these changes, and the generated [TypeScript client code](https://github.com/hasura/graphql-engine-mono/files/9397339/client-typescript.tar.gz) based on that spec.

aa18f65217 server: Move the schema parsers to their own library.
It's about time.

To do this I had to check a few more boxes.

* I copied the flags from `graphql-engine.cabal` to the libraries in `server/lib`.
* I moved `Cacheable` instances of schema parser types beside the typeclass declaration.
* I removed imports of `Hasura.Prelude` from the tests, and rewrote them accordingly.
* I copied the `TestMonad` parse monad into `server/src-test/Hasura/GraphQL/Schema/RemoteTest.hs`, which was using it. I think this could be done with the real thing, but I tried replacing it with constraints and it messed with my head somewhat.
