dfd09159ec Fix JSON encoding issue (fix hasura/graphql-engine#7543 and hasura/graphql-engine#8200)
`encJFromAssocList` is broken since it does not appropriately escape the keys of the JSON dictionaries. Presumably it should.

This is a hotfix for a JSON encoding issue. Longer-term solutions are being discussed in hasura/graphql-engine-mono#3736.

6e1761f8f9 Enable remote joins from remote schemas in the execution engine.
### Description

This PR adds the ability to perform remote joins from remote schemas in the engine. To do so, we alter the definition of an `ExecutionStep` targeting a remote schema: the `ExecStepRemote` constructor now expects a `Maybe RemoteJoins`. This new argument is used when processing the execution step, in the transport layer (either `Transport.HTTP` or `Transport.WebSocket`).

For this `Maybe RemoteJoins` to be extracted from a parsed query, this PR also extends the `Execute.RemoteJoin.Collect` module, to implement "collection" from a selection set. Not only do those new functions extract the remote joins, but they also apply all necessary transformations to the selection sets (such as inserting the necessary "phantom" fields used as join keys).

Finally in `Execute.RemoteJoin.Join`, we make two changes. First, we now always look for nested remote joins, regardless of whether the join we just performed went to a source or a remote schema; and second we adapt our join tree logic according to the special cases that were added to deal with remote server edge cases.

Additionally, this PR refactors / cleans / documents `Execute.RemoteJoin.RemoteServer`. This is not required as part of this change and could be moved to a separate PR if needed (a similar cleanup of `Join` is done independently in #3894). It also introduces a draft of a new documentation page for this project, that will be refined in the release PR that ships the feature (either #3069 or a copy of it).

While this PR extends the engine, it doesn't plug such relationships in the schema, meaning that, as of this PR, the new code paths in `Join` are technically unreachable. Adding the corresponding schema code and, ultimately, enabling the metadata API will be done in subsequent PRs.

### Keeping track of concrete type names

The main change this PR makes to the existing `Join` code is to handle a new reserved field we sometimes use when targeting remote servers: the `__hasura_internal_typename` field. In short, a GraphQL selection set can sometimes "branch" based on the concrete "runtime type" of the object on which the selection happens:

```graphql
query {
  author(id: 53478) {
    ... on Writer {
      name
      articles {
        title
      }
    }
    ... on Artist {
      name
      articles {
        title
      }
    }
  }
}
```

If both of those `articles` are remote joins, we need to be able, when we get the answer, to differentiate between the two different cases. We do this by asking for `__typename`, to be able to decide if we're in the `Writer` or the `Artist` branch of the query.

To avoid further processing / customization of results, we only insert this `__hasura_internal_typename: __typename` field in the query in the case of unions of interfaces AND if we have the guarantee that we will processing the request as part of the remote joins "folding": that is, if there's any remote join in this branch in the tree. Otherwise, we don't insert the field, and we leave that part of the response untouched.

a1886b3729 Generalize remote schemas IR
### Description

This PR is one further step towards remote joins from remote schemas. It introduces a custom partial AST to represent queries to remote schemas in the IR: we now need to augment what used to be a straightforward GraphQL AST with additional information for remote join fields.

This PR does the minimal amount of work to adjust the rest of the code accordingly, using `Void` in all places that expect a type representing remote relationships.

63cff8b731 Experimental backend adapter
This commit introduces an "experimental" backend adapter to the GraphQL Engine.

It defines a high-level interface which will eventually be used as the basis for implementing separate data source query generation & marshaling services that communicate with the GraphQL Engine Server via some protocol.

* [x] Ensure no files are checked in mistakenly
* [x] Consider impact on console, cli, etc.

### Description
>
This PR adds support for adding set-cookie header on the response from the auth webhook. If the set-cookie header is sent by the webhook, it will be forwarded in the graphQL engine response.

Fixes a bug in test-server.sh: testing of get-webhook tests was done by POST method and vice versa. To fix, the parameters were swapped.

### Changelog

- [x] `CHANGELOG.md` is updated with user-facing content relevant to this PR.

### Affected components

- [x] Server
- [ ] Console
- [ ] CLI
- [x] Docs

Closes [#2269](https://github.com/hasura/graphql-engine/issues/2269)

### Solution and Design
>

### Steps to test and verify
>
Please refer to the docs to see how to send the set-cookie header from webhook.

### Limitations, known bugs & workarounds
>
- Support for only set-cookie header forwarding is added
- the value forwarded in the set-cookie header cannot be validated completely, the [Cookie](https://hackage.haskell.org/package/cookie) package has been used to parse the header value and any unnecessary information is stripped off before forwarding the header. The standard given in [RFC6265](https://datatracker.ietf.org/doc/html/rfc6265) has been followed for the Set-Cookie format.

b167120f96 server: add explicit export lists in OSS server and enforce with warning
We'll see if this improves compile times at all, but I think it's worth
doing as at least the most minimal form of module documentation.

This was accomplished by first compiling everything with
-ddump-minimal-imports, and then a bunch of scripting (with help from
ormolu)

**EDIT** it doesn't seem to improve CI compile times but the noise floor is high as it looks like we're not caching library dependencies anymore

503c220840 server: refactor GraphQL.Transport.HTTP.runGQ for readability
I was trying to figure out how to pipe some information from query
execution to the http log recently, and once again stumbled over the
mess that is `runGQ`. Here's an attempt to break it apart a little bit.

The result should by no means be considered final, but I hope it makes it
somewhate easier to understand what's going on in this function. E.g. now it's
once again somewhat visible how execution of queries and mutations differs.
Had to stop somewhere...

The PR is intended to have no functional change. It consists of individual
commits which should be "obviously" such.

Some thoughts and possible follow-up:
- It'd be good to get rid of the ad hoc `Result` data type again eventually,
  but for the moment I think it's better than the tuples that used to be.
- I think we're quite close to reducing the duplication with WebSocket. E.g.
  executeQueryStep and executeMutationStep might be reusable.
- It's tempting to change the caching API slightly, so that the uncached
  response headers don't have to be pulled from the cache lookup result.

71af68e9e5 server: drop HasVersion implicit parameter (closes #2236)
The only real use was for the dubious multitenant option
--consoleAssetsVersion, which actually overrode not just
the assets version. I.e., as far as I can tell, if you pass
--consoleAssetsVersion to multitenant, that version will
also make it into e.g. HTTP client user agent headers as
the proper graphql-engine version.

I'm dropping that option, since it seems unused in production
and I don't want to go to the effort of fixing it, but am happy
to look into that if folks feels strongly that it should be
kept.

(Reason for attacking this is that I was looking into http
client things around blacklisting, and the versioning thing
is a bit painful around http client headers.)

fbd1262ea6 server: operation timeout with postgres cancelling
### Description

This PR implements operation timeouts, as specced in #1232.

RFC: [rfcs/operation-timeout-api-limits.md](c025a90fe9/rfcs/operation-timeout-api-limits.md)

There's still some things to be done (tests and docs most notably), but apart from that it can
be reviewed. I'd still appreciate feedback on the RFC!

TODO:
- [x] break out the `ApiLimits` refactoring into a separate PR: #2103
- [x] finish the `pg-client-hs` PR: https://github.com/hasura/pg-client-hs/pull/39
- [x] remove configurability, after testing, prior to merging
- [ ] tests: #2390 has some tests that I've run locally to confirm things work on a fundamental level
- [x] changelog
- [x] documentation
- [x] fill in the detailed PR checklist

### Changelog

- [x] `CHANGELOG.md` is updated with user-facing content relevant to this PR. If no changelog is required, then add the `no-changelog-required` label.

### Affected components

- [x] Server
- [ ] Console
- [ ] CLI
- [x] Docs
- [ ] Tests

### Related Issues

Product spec: #1232.

### Solution and Design

Compare `rfcs/operation-timeout-api-limits.md`.

### Steps to test and verify

Configure operation timeouts, e.g. by posting

```
{
  "type": "set_api_limits",
  "args": {
    "operation_timeout": {
      "global": 3
    }
  }
}
```

to `v1/metadata` to set an operation timeout of 3s. Then verify that
1. non-admin queries that take longer than 3s time out with a nice error message
2. that those queries return after ~3s (at least for postgres)
3. also that everything else still works as usual

### Limitations, known bugs & workarounds
- while this will cause slow queries against any backends to fail, it's only verified to actually interrupt queries against postgres
- this will only successfully short-cut (cancel) queries to postgres if the database server is responsive

#### Catalog upgrade
Does this PR change Hasura Catalog version?
- [x] No

#### Metadata

Does this PR add a new Metadata feature?
- [x] Yes
  - Does `run_sql` auto manages the new metadata through schema diffing?
    - [x] Not required
  - Does `run_sql` auto manages the definitions of metadata on renaming?
    - [x] Not required
  - Does `export_metadata`/`replace_metadata` supports the new metadata added?
    - [x] Yes

#### GraphQL
- [x] No new GraphQL schema is generated

#### Breaking changes

- [x] No Breaking changes

For in-flight branches, simply merging changes from `main` will result in merge conflicts.
To avoid this, update your branch using the following instructions. Replace `<format-commit>`

bdacf1bd23 server: remove ApplicativeDo from default extensions
I spent half the day reducing a weird compile failure here https://github.com/hasura/graphql-engine-mono/pull/1593/files#r713102990 to this https://gitlab.haskell.org/ghc/ghc/-/issues/17768#note_378004. Seems ApplicativeDo makes a mess of non-applicative monadic do in some cases. Given our rather localized use of ApplicativeDo, seemed a good idea to remove it from the list of default extensions.

It appears that ApplicativeDo also buries some unused return value warnings, so this PR also silences those. We should check that none of those warnings were warranted though.

d900a65399 server: Reduce and localize CPP usage
Some of our use of CPP causes trouble for ormolu, compare https://github.com/tweag/ormolu/issues/774.
Specifically, for understandable reasons, it can't deal well with `#ifdef` use that is not at the top-level.

This PR removes the problematic usage in ways that I hope are also a net non-loss regardless of helping
out ormolu (or other tooling).

- The default value for enabled APIs moves to the top level, next to the command line help, so

7bead93827 server: remove remnants of query plan caching (fix #1795)
Query plan caching was introduced by - I believe - hasura/graphql-engine#1934 in order to reduce the query response latency. During the development of PDV in hasura/graphql-engine#4111, it was found out that the new architecture (for which query plan caching wasn't implemented) performed comparably to the pre-PDV architecture with caching. Hence, it was decided to leave query plan caching until some day in the future when it was deemed necessary.

Well, we're in the future now, and there still isn't a convincing argument for query plan caching. So the time has come to remove some references to query plan caching from the codebase. For the most part, any code being removed would probably not be very well suited to the post-PDV architecture of query execution, so arguably not much is lost.

Apart from simplifying the code, this PR will contribute towards making the GraphQL schema generation more modular, testable, and easier to profile. I'd like to eventually work towards a situation in which it's easy to generate a GraphQL schema parser *in isolation*, without being connected to a database, and then parse a GraphQL query *in isolation*, without even listening any HTTP port. It is important that both of these operations can be examined in detail, and in isolation, since they are two major performance bottlenecks, as well as phases where many important upcoming features hook into.

Implementation

The following have been removed:
- The entirety of `server/src-lib/Hasura/GraphQL/Execute/Plan.hs`
- The core phases of query parsing and execution no longer have any references to query plan caching. Note that this is not to be confused with query *response* caching, which is not affected by this PR. This includes removal of the types:
- - `Opaque`, which is replaced by a tuple. Note that the old implementation was broken and did not adequately hide the constructors.
- - `QueryReusability` (and the `markNotReusable` method). Notably, the implementation of the `ParseT` monad now consists of two, rather than three, monad transformers.
- Cache-related tests (in `server/src-test/Hasura/CacheBoundedSpec.hs`) have been removed .
- References to query plan caching in the documentation.
- The `planCacheOptions` in the `TenantConfig` type class was removed. However, during parsing, unrecognized fields in the YAML config get ignored, so this does not cause a breaking change. (Confirmed manually, as well as in consultation with @sordina.)
- The metrics no longer send cache hit/miss messages.

There are a few places in which one can still find references to query plan caching:

- We still accept the `--query-plan-cache-size` command-line option for backwards compatibility. The `HASURA_QUERY_PLAN_CACHE_SIZE` environment variable is not read.

d91029ad51 [gardening] remove all traverse functions from RQL.IR
### Description

This PR removes all `fmapX` and `traverseX` functions from RQL.IR, favouring instead `Functor` and `Traversable` instances throughout the code. This was a relatively straightforward change, except for two small pain points: `AnnSelectG` and `AnnInsert`. Both were parametric over two types `a` and `v`, making it impossible to make them traversable functors... But it turns out that in every single use case, `a ~ f v`. By changing those types to take such an `f :: Type -> Type` as an argument instead of `a :: Type` makes it possible to make them functors.

The only small difference is for `AnnIns`, I had to introduce one `Identity` transformation for one of the `f` parameters. This is relatively straightforward.

### Notes

This PR fixes the most verbose BigQuery hint (`let` instead of `<- pure`).

8a77386fcf server: IR for DB-DB joins
### Description

This PR adds the required IR for DB to DB joins, based on @paf31 and @0x777 's `feature/db-to-db` branch.

To do so, it also refactors the IR to introduce a new type parameter, `r`, which is used to recursively constructs the `v` parameter of remote QueryDBs. When collecting remote joins, we replace `r` with `Const Void`, indicating at the type level that there cannot be any leftover remote join.

Furthermore, this PR refactors IR.Select for readability, moves some code from IR.Root to IR.Select to avoid having to deal with circular dependencies, and makes it compile by adding `error` in all new cases in the execution pipeline.

The diff doesn't make it clear, but most of Select.hs is actually unchanged. Declarations have just been reordered by topic, in the following order:
- type declarations
- instance declarations
- type aliases
- constructor functions
- traverse functions

e8e4f30dd6 server: support remote relationships on SQL Server and BigQuery (#1497)
Remote relationships are now supported on SQL Server and BigQuery. The major change though is the re-architecture of remote join execution logic. Prior to this PR, each backend is responsible for processing the remote relationships that are part of their AST.

This is not ideal as there is nothing specific about a remote join's execution that ties it to a backend. The only backend specific part is whether or not the specification of the remote relationship is valid (i.e, we'll need to validate whether the scalars are compatible).

The approach now changes to this:

1. Before delegating the AST to the backend, we traverse the AST, collect all the remote joins while modifying the AST to add necessary join fields where needed.

1. Once the remote joins are collected from the AST, the database call is made to fetch the response. The necessary data for the remote join(s) is collected from the database's response and one or more remote schema calls are constructed as necessary.

1. The remote schema calls are then executed and the data from the database and from the remote schemas is joined to produce the final response.

### Known issues

1. Ideally the traversal of the IR to collect remote joins should return an AST which does not include remote join fields. This operation can be type safe but isn't taken up as part of the PR.

1. There is a lot of code duplication between `Transport/HTTP.hs` and `Transport/Websocket.hs` which needs to be fixed ASAP. This too hasn't been taken up by this PR.

1. The type which represents the execution plan is only modified to handle our current remote joins and as such it will have to be changed to accommodate general remote joins.

1. Use of lenses would have reduced the boilerplate code to collect remote joins from the base AST.

1. The current remote join logic assumes that the join columns of a remote relationship appear with their names in the database response. This however is incorrect as they could be aliased. This can be taken up by anyone, I've left a comment in the code.

### Notes to the reviewers

I think it is best reviewed commit by commit.

1. The first one is very straight forward.

1. The second one refactors the remote join execution logic but other than moving things around, it doesn't change the user facing functionality.  This moves Postgres specific parts to `Backends/Postgres` module from `Execute`. Some IR related code to `Hasura.RQL.IR` module.  Simplifies various type class function signatures as a backend doesn't have to handle remote joins anymore

1. The third one fixes partial case matches that for some weird reason weren't shown as warnings before this refactor

1. The fourth one generalizes the validation logic of remote relationships and implements `scalarTypeGraphQLName` function on SQL Server and BigQuery which is used by the validation logic. This enables remote relationships on BigQuery and SQL Server.

da8f6981d4 server: reduce the number of backend dispatches
Fixes https://github.com/hasura/graphql-engine-mono/issues/712

Main point of interest: the `Hasura.SQL.Backend` module.

This PR creates an `Exists` type indexed by indexed type and packed constraint while hiding all of its complexity by not exporting the constructor.

Existential constructors/types which are no longer (directly) existential:
- [X] BackendSourceInfo :: BackendSourceInfo
- [x] BackendSourceMetadata :: BackendSourceMetadata
- [x] MOSourceObjId :: MetadatObjId
- [x] SOSourceObj :: SchemaObjId
- [x] RFDB :: RootField
- [x] LQP :: LiveQueryPlan
- [x] ExecutionStep :: ExecStepDB

This PR also removes ALL usages of `Typeable.cast` from our codebase. We still need to derive `Typeable` in a few places in order to be able to derive `Data` in one place. I have not dug deeper to see why this is needed.

92026b769f [Preview] Inherited roles for postgres read queries
fixes #3868

docker image - `hasura/graphql-engine:inherited-roles-preview-48b73a2de`

Note:

To be able to use the inherited roles feature, the graphql-engine should be started with the env variable `HASURA_GRAPHQL_EXPERIMENTAL_FEATURES` set to `inherited_roles`.

Introduction
------------

This PR implements the idea of multiple roles as presented in this [paper](https://www.microsoft.com/en-us/research/wp-content/uploads/2016/02/FGALanguageICDE07.pdf). The multiple roles feature in this PR can be used via inherited roles. An inherited role is a role which can be created by combining multiple singular roles. For example, if there are two roles `author` and `editor` configured in the graphql-engine, then we can create a inherited role with the name of `combined_author_editor` role which will combine the select permissions of the `author` and `editor` roles and then make GraphQL queries using the `combined_author_editor`.

How are select permissions of different roles are combined?
------------------------------------------------------------

A select permission includes 5 things:

1. Columns accessible to the role
2. Row selection filter
3. Limit
4. Allow aggregation
5. Scalar computed fields accessible to the role

 Suppose there are two roles, `role1` gives access to the `address` column with row filter `P1` and `role2` gives access to both the `address` and the `phone` column with row filter `P2` and we create a new role `combined_roles` which combines `role1` and `role2`.

Let's say the following GraphQL query is queried with the `combined_roles` role.

```graphql
query {
   employees {
     address
     phone
   }
}
```

This will translate to the following SQL query:

```sql

 select
    (case when (P1 or P2) then address else null end) as address,
    (case when P2 then phone else null end) as phone
 from employee
 where (P1 or P2)
```

The other parameters of the select permission will be combined in the following manner:

1. Limit - Minimum of the limits will be the limit of the inherited role
2. Allow aggregations - If any of the role allows aggregation, then the inherited role will allow aggregation
3. Scalar computed fields - same as table column fields, as in the above example

APIs for inherited roles:
----------------------

1. `add_inherited_role`

`add_inherited_role` is the [metadata API](https://hasura.io/docs/1.0/graphql/core/api-reference/index.html#schema-metadata-api) to create a new inherited role. It accepts two arguments

`role_name`: the name of the inherited role to be added (String)
`role_set`: list of roles that need to be combined (Array of Strings)

Example:

```json
{
  "type": "add_inherited_role",
  "args": {
      "role_name":"combined_user",
      "role_set":[
          "user",
          "user1"
      ]
  }
}
```

After adding the inherited role, the inherited role can be used like single roles like earlier

Note:

An inherited role can only be created with non-inherited/singular roles.

2. `drop_inherited_role`

The `drop_inherited_role` API accepts the name of the inherited role and drops it from the metadata. It accepts a single argument:

`role_name`: name of the inherited role to be dropped

Example:

```json

{
  "type": "drop_inherited_role",
  "args": {
      "role_name":"combined_user"
  }
}
```

Metadata
---------

The derived roles metadata will be included under the `experimental_features` key while exporting the metadata.

```json
{
  "experimental_features": {
    "derived_roles": [
      {
        "role_name": "manager_is_employee_too",
        "role_set": [
          "employee",
          "manager"
        ]
      }
    ]
  }
}
```

Scope
------

Only postgres queries and subscriptions are supported in this PR.

Important points:
-----------------

1. All columns exposed to an inherited role will be marked as `nullable`, this is done so that cell value nullification can be done.

TODOs
-------

- [ ] Tests
   - [ ] Test a GraphQL query running with a inherited role without enabling inherited roles in experimental features
   - [] Tests for aggregate queries, limit, computed fields, functions, subscriptions (?)
   - [ ] Introspection test with a inherited role (nullability changes in a inherited role)
- [ ] Docs
- [ ] Changelog

06b599b747 server: multitenant metadata storage
The metadata storage implementation for graphql-engine-multitenant.

- It uses a centralized PG database to store metadata of all tenants (instead of per tenant database)
- Similarly, it uses a single schema-sync listener thread per MT worker (instead of listener thread per tenant) (PS: although, the processor thread is spawned per tenant)
- 2 new flags are introduced - `--metadataDatabaseUrl` and (optional) `--metadataDatabaseRetries`

Internally, a "metadata mode" is introduced to indicate an external/managed store vs a store managed by each pro-server.

To run :
- obtain the schema file (located at `pro/server/res/cloud/metadata_db_schema.sql`)
- apply the schema on a PG database
- set the `--metadataDatabaseUrl` flag to point to the above database
- run the MT executable

The schema (and its migrations) for the metadata db is managed outside the MT worker.

### New metadata

The following is the new portion of `Metadata` added :

```yaml
version: 3
metrics_config:
  analyze_query_variables: true
  analyze_response_body: false
api_limits:
  disabled: false
  depth_limit:
    global: 5
    per_role:
      user: 7
      editor: 9
  rate_limit:
    per_role:
      user:
        unique_params:
        - x-hasura-user-id
        - x-hasura-team-id
        max_reqs_per_min: 20
    global:
      unique_params: IP
      max_reqs_per_min: 10
```

- In Pro, the code around fetching/updating/syncing pro-config is removed
- That also means, `hdb_pro_catalog` for keeping the config cache is not required. Hence the `hdb_pro_catalog` is also removed
- The required config comes from metadata / schema cache

### New Metadata APIs

- `set_api_limits`
- `remove_api_limits`
- `set_metrics_config`
- `remove_metrics_config`

#### `set_api_limits`

```yaml
type: set_api_limits
args:
  disabled: false
  depth_limit:
    global: 5
    per_role:
      user: 7
      editor: 9
  rate_limit:
    per_role:
      anonymous:
         max_reqs_per_min: 10
         unique_params: "ip"
      editor:
        max_reqs_per_min: 30
        unique_params:
        - x-hasura-user-id
      user:
        unique_params:
        - x-hasura-user-id
        - x-hasura-team-id
        max_reqs_per_min: 20
    global:
      unique_params: IP
      max_reqs_per_min: 10
```

#### `remove_api_limits`

```yaml
type: remove_api_limits
args: {}
```

#### `set_metrics_config`

```yaml
type: set_metrics_config
args:
  analyze_query_variables: true
  analyze_response_body: false
```

#### `remove_metrics_config`

```yaml
type: remove_metrics_config
args: {}
```

  - [ ] benchmark with few tenants having large metadata (100+ tables etc.)
  - [ ] when user moves regions (https://github.com/hasura/lux/issues/1717)
    - [ ] metadata has to be migrated from one regional PG to another
    - [ ] migrate metrics data as well ?
      - [ ] operation logs
      - [ ] regression test runs

- [ ] find a way to share the schema files with the infra team
