8e88e73a52 server/mssql: add cascade to mssql_run_sql
<!-- Thank you for ss in the Title above ^ -->

## Description
<!-- Please fill thier. -->
<!-- Describe the changes from a user's perspective -->
We don't have dependency reporting mechanism for `mssql_run_sql` API i.e when a database object (table, column etc.) is dropped through the API we should raise an exception if any dependencies (relationships, permissions etc.) with the database object exists in the metadata.

This PR addresses the above mentioned problem by
-> Integrating transaction to the API to rollback the SQL query execution if dependencies exists and exception is thrown
-> Accepting `cascade` optional field in the API payload to drop the dependencies, if any
-> Accepting `check_metadata_consistency` optional field to bypass (if value set to `false`) the dependency check

### Related Issues
<!-- Please make surt title -->
<!-- Add the issue number below (e.g. #234) -->
Close #1853

### Solution and Design
<!-- How is this iss -->
<!-- It's better if we elaborate -->
The design/solution follows the `run_sql` API implementation for Postgres backend.

### Steps to test and verify
<!-- If this is a fehis is a bug-fix, how do we verify the fix? -->
- Create author - article tables and track them
- Defined object and array relationships
- Try to drop the article table without cascade or cascade set to `false`
- The server should raise the relationship dependency exists exception

c4536e801c Correctly translate permissions on functions to SQL, and simplify Bool Exp IR
Prior to this change, the SQL expression that resulted from translating permissions on functions would refer to the table of the function's return type, rather than the set of rows selected from the function being called.

Now the SQL that results from translating permissions correctly refer to the selected rows.

This PR also contains the suggested additions of https://github.com/hasura/graphql-engine-mono/pull/2563#discussion_r726116863, which simplifies the Boolean Expression IR, but in turn makes the Schema Dependency Discovery algorithm work a bit harder.

We are changing the definition of `data OpExpG`, but the format accepted by its JSON parser remains unchanged. While there does exist a generically derived `instance ToJSON OpExpG` this is only used in the (unpublished) `/v1/metadata/dump_internal_state` API.

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

11a454c2d6 server, pro: actually reformat the code-base using ormolu
This commit applies ormolu to the whole Haskell code base by running `make format`.

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>`
by the hash of *this* commit.

$ git checkout my-feature-branch
$ git merge <format-commit>^    # and resolve conflicts normally
$ make format
$ git commit -a -m "reformat with ormolu"
$ git merge -s ours post-ormolu

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.

21254256a1 Improve error messages of Metadata API.
### Description

This PR improves error messages in our metadata API by displaying a message with the name of the failing command and a link to our documentation. Furthermore, it harmonizes our internal uses of `withObject`, to respect the convention of using the Haskell type name, now that the Aeson error message is displayed as an "internal error message".

9ca0bc1e5c server: remove identity notion from table columns
>

### Description
>
While adding [insert mutation schema parser for MSSQL backend](https://github.com/hasura/graphql-engine-mono/pull/2141) I also included [identity](https://en.wikipedia.org/wiki/Identity_column) notion to table columns across all backends. In MSSQL we cannot insert any value (even `DEFAULT` expression) into Identity columns. This behavior of identity columns is not same in Postgres as we can insert values. This PR drops the notion of identity in the column info. The context of identity columns for MSSQL is carried in `ExtraTableMetadata` type.

fe035125f4 server: drop LazyTxT newtype
This is a follow-up to #1959.

Today, I spent a while in review figuring out that a harmless PR change didn't do anything,
because it was moving from a `runLazy...` to something without the `Lazy`. So let's get
that source of confusion removed.

This should be a bit easier to review commit by commit, since some of the functions had
confusing names. (E.g. there was a misnamed `Migrate.Internal.runTx` before.)

The change should be a no-op.

a5589c185b Fix nullability of nested objrel inserts (fix hasura/graphql-engine#7484)
### Description

During the PDV refactor that led to 2.0, we broke an undocumented and untested semantic of inserts: accepting _explicit_ null values in nested object inserts.

In short: in the schema, we often distinguish between _explicit_ null values `{id: 3, author: null}` and _implicit_ null values that correspond to the field being omitted `{id: 3}`. In this particular case, we forgot to accept explicit null values. Since the field is optional (meaning we accept implicit null values), it was nullable in the schema, like it was in pre-PDV times. But in practice we would reject explicit nulls.

This PR fixes this, and adds a test. Furthermore, it does a bit of a cleanup of the Mutation part of the schema, and more specifically of all insertion code.

fe8eabff19 server: fix the nullability of object relationships (fix hasura/graphql-engine#7201)
When adding object relationships, we set the nullability of the generated GraphQL field based on whether the database backend enforces that the referenced data always exists. For manual relationships (corresponding to `manual_configuration`), the database backend is unaware of any relationship between data, and hence such fields are always set to be nullable.

For relationships generated from foreign key constraints (corresponding to `foreign_key_constraint_on`), we distinguish between two cases:

1. The "forward" object relationship from a referencing table (i.e. which has the foreign key constraint) to a referenced table. This should be set to be non-nullable when all referencing columns are non-nullable. But in fact, it used to set it to be non-nullable if *any* referencing column is non-nullable, which is only correct in Postgres when `MATCH FULL` is set (a flag we don't consider). This fixes that by changing a boolean conjunction to a disjunction.
2. The "reverse" object relationship from a referenced table to a referencing table which has the foreign key constraint. This should always be set to be nullable. But in fact, it used to always be set to non-nullable, as was reported in hasura/graphql-engine#7201. This fixes that.

Moreover, we have moved the computation of the nullability from `Hasura.RQL.DDL.Relationship` to `Hasura.GraphQL.Schema.Select`: this nullability used to be passed through the `riIsNullable` field of `RelInfo`, but for array relationships this information is not actually used, and moreover the remaining fields of `RelInfo` are already enough to deduce the nullability.

This also adds regression tests for both (1) and (2) above.

c9481d4599 server: remove align, These(..) from Prelude
This removes the module re-exports of [Data.Align](https://hackage.haskell.org/package/semialign-1.2/docs/Data-Align.html) and [Data.These](https://hackage.haskell.org/package/these-1.1.1.1/docs/Data-These.html) from `Hasura.Prelude`. The reasoning being that they're not used widely and reasonably obscure, and that being explicit about the imports makes for an easier to understand codebase.

(I spent longer than I'd have liked earlier today figuring out where `align` in multitenant came from.
The right one not showing up on the first hoogle page doesn't help. Yes, better tool use could have
avoided that, but still...)

Do feel free to shoot this down, I won't insist on the change.

When limits are not disabled, but neither node nor depth limit
is configured, we no longer count nodes/depth uselessly.

fa152d842d server/postgres: optimize SQL query generation with LIMITs
>

### Description
>
This PR supersedes https://github.com/hasura/graphql-engine-mono/pull/1484. Apply `limit` to the table selection before joining relationship rows to improve query performance.

### 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

### Related Issues
->
Fix https://github.com/hasura/graphql-engine/issues/5745

### Solution and Design
>
Prior to this change, we apply `LIMIT` and `OFFSET` to the outer selection from sub-query which includes joins for relationships. Now, we move `LIMIT` and `OFFSET` (if present) to inner selection of base table. But, this isn't done always! If there are order by relationships' columns we apply at the outer selection. To know more, please refer to [source code note](https://github.com/hasura/graphql-engine-mono/pull/2078/files#diff-46d868ee45d3eaac667cebb34731f573c77d5c9c8097bb9ccf1115fc07f65bfdR652).

a978b6d683 Remove several outdated backend constraints
## Description

This PR removes as many constraints as possible from Backend without refactoring the code. Thanks to #1844, a few ToJSON functions can be removed from the IR, and several constraints were simply redundant.

This PR borrows from similar work done as part of #1666.

## Note

To remove constraints more aggressively, I have explored the possibility of _removing Representable altogether_, in a [separate commit](https://github.com/hasura/graphql-engine-mono/compare/nicuveo/remove-extension-constraints..nicuveo/tentative-remove-representable). I am not convinced it's a good idea in terms of readability of the code, but it's a possibility.

Further work includes deciding what we want to do with `Show` and `ToTxt`; see #1747.

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.

cc6c86aeab Clean metadata arguments
## Description

Thanks to #1664, the Metadata API types no longer require a `ToJSON` instance. This PR follows up with a cleanup of the types of the arguments to the metadata API:
- whenever possible, it moves those argument types to where they're used (RQL.DDL.*)
- it removes all unrequired instances (mostly `ToJSON`)

This PR does not attempt to do it for _all_ such argument types. For some of the metadata operations, the type used to describe the argument to the API and used to represent the value in the metadata are one and the same (like for `CreateEndpoint`). Sometimes, the two types are intertwined in complex ways (`RemoteRelationship` and `RemoteRelationshipDef`). In the spirit of only doing uncontroversial cleaning work, this PR only moves types that are not used outside of RQL.DDL.

Furthermore, this is a small step towards separating the different types all jumbled together in RQL.Types.

## Notes

This PR also improves several `FromJSON` instances to make use of `withObject`, and to use a human readable string instead of a type name in error messages whenever possible. For instance:
- before: `expected Object for Object, but encountered X`
  after: `expected Object for add computed field, but encountered X`
- before: `Expecting an object for update query`
  after: `expected Object for update query, but encountered X`

This PR also renames `CreateFunctionPermission` to `FunctionPermissionArgument`, to remove the quite surprising `type DropFunctionPermission = CreateFunctionPermission`.

This PR also deletes some dead code, mostly in RQL.DML.

This PR also moves a PG-specific source resolving function from DDL.Schema.Source to the only place where it is used: App.hs.

49f40a44f0 Enforce that backends use the properly resolved environment variables.
## Description

This PR fixes an oversight in the implementation of the resolvers of different backends. To implement resolution from environment variables, both MSSQL and BigQuery were directly fetching the process' environment variables, instead of using the careful curated set we thread from main. It was working just fine on OSS, but is failing on Cloud.

This PR fixes this by adding an additional argument to `resolveSourceConfig`, to ensure that backends always use the correct set of variables.

0aaf006c25 server: add metadata for DB-DB remote joins
### Description

This PR is the first of several PRs meant to introduce Generalized Joins. In this first PR, we add non-breaking changes to the Metadata types for DB-to-DB remote joins. Note that we are currently rejecting the new remote join format in order to keep folks from breaking their metadata (in case of a downgrade). These issues will be tackled (and JSON changes reverted) in subsequent PRs.

This PR also changes the way we construct the schema cache, and breaks the way we process sources in two steps: we first resolve each source and construct a cache of their tables' raw info, then in a second step we build the source output. This is so that we have access to the target source's tables when building db-to-db relationships.

### Notes

- this PR contains a few minor cleanups of the schema
- it also fixes a bug in how we do renames in remote schema relationships
- it introduces cross-source schema dependencies

83045a4459 server: fix erroneous Eq instance on Metadata Object
During the "generalization" of the code, we removed the [generated instances](9d63187803 (diff-7b8382ab20e441fa214586be491eb6f7ca904d8b20ed97894c16a339be45219aL72)) of `Eq` and `Hashable` in favour of manually written ones, because for a time we were struggling with `AnyBackend`.

In the process, we lost one constructor, `MOEndpoint`. It's unlikely to have ever been an issue, since duplicate endpoints are unlikely, but it is nonetheless wrong.

This PR simply goes back to default derived instances, now that we can, fixing the problem and making the code simpler.

---

However, after filing this PR, I realized **it broke rest endpoint tests**. Upon closer inspection, it turns out that while we had proper checks in place, because of this bug we were actually failing _differently_ during metadata checks. This PR actually improves error messages for invalid endpoint configurations?! 🙀

This is a tiny bit scary. ^^'

0a9382f2dc [gardening] remove Alias from Backend
### Description

In our haste to generalize everything for MSSQL, we put every single "suspicious" type in Backend, including ones that weren't required. `Alias` is one of those: it's only used in a type alias, and is actually just an implementation detail of the translation layer. This PR removes it.

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`).

6ed800abaa [gardening] Introduce PartialArbitrary
### Context

One of the ways we use the Backend type families is to use `Void` for all types for which a backend has no representation; this allows us to make some branches of our metadata and IR unrepresentable, making some functions total, where they would have to handle those unsupported cases otherwise.

However, one of the biggest features, functions, cannot be cut that way, due to one of the constraints on `FunctionName b`: the metadata generator requires it to have an `Arbitrary` instance, and `Arbitrary` does not have a recovery mechanism which would allow for a `Void` instance...

### Description

This PR solves this problem and removes the `Arbitrary` constraints in `Backend`. To do so, it introduces a new typeclass: `PartialArbitrary`, which is very similar to `Arbitrary`, except that it returns a `Maybe (Gen a)`, allowing for `Void` to have a well-formed instance. An `Arbitrary` instance for `Metadata` can easily be retrieved with `arbitrary = fromJust . partialArbitrary`.

Furthermore, `PartialArbitrary` has a generic implementation, inspired by the one in `generic-arbitrary`, which automatically prunes branches that return `Nothing`, allowing to automatically construct most types. Types that don't have a type parameter and therefore can't contain `Void` can easily get their `PartialArbitrary` instance from `Arbitrary` with `partialArbitrary = Just arbitrary`. This is what a default overlappable instance provides.

In conjunction with other cleanups in #1666, **this allows for Void function names**.

### Notes

While this solves the stated problem, there are other possible solutions we could explore, such as:
- switching from QuickCheck to a library that supports that kind of pruning natively
- removing the test altogether, and dropping all notion of Arbitrary from the code

There are also several things we could do with the Generator module:
- move it out of RQL.DDL.Metadata, to some place that makes more sense
- move ALL Arbitrary instances in the code to it, since nothing else uses Arbitrary
- or, to the contrary, move all those Arbitrary instances alongside their types, to avoid an orphan instance

404551acdb server: fix major issue with JSON instances of AnyBackend
### Description
This PR fixes a major issue in the JSON instances of `AnyBackend`: they were not symmetrical! `FromJSON` always made the assumption that the value was an object, and that it contained a "kind" field if it happened to not be a Postgres value. `ToJSON` did NOT insert said field in the output, and did not enforce that the output was an object.

....however, it worked, because nowhere in the code did we yet rely on those being symmetrical. They are both used only once:
- `parseJSON` was used to decode a `Metadata` object, but the matching `toJSON` instance, which is heavily customized, does insert the "kind" field properly
- `toJSON` was only used on the `SchemaCache`, which has no corresponding `FromJSON` instance, since we only serialize it in debug endpoints

This PR makes no attempt at making the instances symmetrical. Instead, it implements simpler functions, and pushes the problem of identifying the proper backend (if any) to the call sites.

### Notes

Additionally, it cleans up some instances that were manually written where they could be auto-generated. In the process, this PR changes the semantics of `Show`, since the stock derived instance will include the constructor name, where before it was skipped. I think it is preferable.

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.

d3611af58d server: lazy event catalog initialisation
event catalog:
- `hdb_catalog` is no longer automatically created
- catalog is initialised when the first event trigger is created
- catalog initialisation is done during the schema cache build, using `ArrowCache` so it is only run in response to a change to the set of event triggers

event queue:
- `processEventQueue` thread is prevented from starting when `HASURA_GRAPHQL_EVENTS_FETCH_INTERVAL=0`
- `processEventQueue` thread only processes sources for which at least one event trigger exists in some table in the source

c737ce992d Schema-Sync Improvements for Cloud, Pro, and OSS - Version Checking for Metadata (#738)
Modifying schema-sync implementation to use polling for OSS/Pro. Invalidations are now propagated via the `hdb_catalog.hdb_schema_notifications` table in OSS/Pro. Pattern followed is now a Listener/Processor split with Cloud listening for changes via a LISTEN/NOTIFY channel and OSS polling for resource version changes in the metadata table. See issue #460 for more details.

91710bba58 server: use relative paths in TH splices
While debugging issues with HLS, Reed Mullanix noticed that we don't use relative paths. This leads to problems when using HLS + Emacs due to a bug in `lsp-mode` which prevents it from finding the correct project root.

However, it is still a good practice to use relative paths in TH for other reasons, including being able to import these modules in GHCI.

This PR should make it so HLS-1.0 & emacs provide type inference, imports, etc., in all modules in our codebase.

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.

0c1016e065 Inconsistent metadata support for REST endpoints
Previously invalid REST endpoints would throw errors during schema cache build.

This PR changes the validation to instead add to the inconsistent metadata objects in order to allow use of `allow_inconsistent_metadata` with inconsistent REST endpoints.

All non-fatal endpoint definition errors are returned as inconsistent metadata warnings/errors depending on the use of `allow_inconsistent_metadata`. The endpoints with issues are then created and return informational runtime errors when they are called.

Console impact when creating endpoints is that error messages now refer to metadata inconsistencies rather than REST feature at the top level:

Note: Conflicting endpoints generate one error per conflicting set of endpoints due to the implementation of `groupInconsistentMetadataById` and `imObjectIds`. This is done to ensure that error messages are terse, but may pose errors if there are some assumptions made surrounding `imObjectIds`.

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

08da0c63b6 REST Endpoints - Prohibit Invalid slashes, duplicate variables, non-singular query definitions, subscriptions
Resolves Issues:

* https://github.com/hasura/graphql-engine-mono/issues/658 - Invalid Slashes
* https://github.com/hasura/graphql-engine-mono/issues/628 - Subscriptions

Implementation:

* Moved some logic from Endpoint.hs to allow reuse of splitting url into PathSegments.
* Additional validation steps alongside checking for overlapping routes
* Logging potential misuse of GET for mutations

Future Work:

* [ ] GET is allowed for mutations (Ignore/Log warning for Now)
* [ ] Add to scInconsistentObjs rather than throwing error
  * Add information to scInconsistentObjs instead of raising errors directly.

TODO:

* [x] Duplicate variable segments with the same name in the location should not be allowed
* [x] We should throw an error on trailing and leading slashes and URLs which contain empty segments
* [x] Endpoints can be created using subscriptions. But the error only shows at the time of the query
* [x] Tests

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: {}
```

#### TODO
- [x] on-prem pro implementation for `MonadMetadataStorage`
- [x] move the project config from Lux to pro metadata (PR: #379)
- [ ] console changes for pro config/api limits, subscription workers (cc @soorajshankar @beerose)
- [x] address other minor TODOs
  - [x] TxIso for `MonadSourceResolver`
  - [x] enable EKG connection pool metrics
  - [x] add logging of connection info when sources are added?
  - [x] confirm if the `buildReason` for schema cache is correct
- [ ] testing
- [x] 1.3 -> 1.4 cloud migration script (#465; PR: #508)
  - [x] one-time migration of existing metadata from users' db to centralized PG
  - [x] one-time migration of pro project config + api limits + regression tests from metrics API  to metadata
- [ ] integrate with infra team (WIP - cc @hgiasac)
  - [x] benchmark with 1000+ tenants + each tenant making read/update metadata query every second (PR: https://github.com/hasura/graphql-engine-mono/pull/411)
  - [ ] 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

4815fcd500 server: progress on generic metadata
This PR generalizes a bunch of metadata structures.

Most importantly, it changes `SourceCache` to hold existentially quantified values:
```
data BackendSourceInfo =
  forall b. Backend b => BackendSourceInfo (SourceInfo b)

type SourceCache = HashMap SourceName BackendSourceInfo
```

This changes a *lot* of things throughout the code. For now, all code using the schema cache explicitly casts sources to Postgres, meaning that if any non-Postgres `SourceInfo` makes it to the cache, it'll be ignored.

That means that after this PR is submitted, we can split work between two different aspects:
  - creating `SourceInfo` for other backends
  - handling those other sources down the line

6e752a7876 server: add type information to aggregates and stringify them (closes #5704)
Fixes https://github.com/hasura/graphql-engine/issues/5704 by checking, for aggregate fields whether we are handling a numeric aggregation.

This PR also adds type information to `ColFld` such that we know the type of the field.

This is the second attempt. See #319 for a less invasive approach. @nicuveo suggested type information might be useful, and since it wasn't hard to add, I think this version is better as well.

44347d2d74 server: template the schema and table names in the event trigger PG functions
Earlier, while creating the event trigger's internal postgres trigger, we used to get the name of the table from the `TG_TABLE_NAME` special trigger variable. Using this with normal tables works fine, but it breaks when the parent table is partitioned because we associate the ET configuration in the schema only with the original table (as it should be).

In this PR, we supply the table name and schema name through template variables instead of using `TG_TABLE_NAME` and `TG_TABLE_SCHEMA`, so that event triggers work with a partitioned table as well.

TODO:

- [x] Changelog
- [x] unit test (ET on partition table)

3c3ed55914 server: schema that grows (#105)
This PR makes a bunch of schema generation code in Hasura.GraphQL.Schema backend-agnostic, by moving the backend-specific parts into a new BackendSchema type class. This way, the schema generation code can be reused for other backends, simply by implementing new instances of the BackendSchema type class.

This work is now in a state where the schema generators are sufficiently generic to accept the implementation of a new backend. That means that we can start exposing MS SQL schema. Execution is not implemented yet, of course.
The branch currently does not support computed fields or Relay. This is, in a sense, intentional: computed field support is normally baked into the schema generation (through the fieldSelection schema generator), and so this branch shows a programming technique that allows us to expose certain GraphQL schema depending on backend support. We can write support for computed fields and Relay at a later stage.

* dev.sh: bump version due to addition of croniter python dependency

* server: fix an introspection query caching issue (fix #4547) (#4661)

Introspection queries accept variables, but we need to make sure to
also touch the variables that we ignore, so that an introspection
query is marked not reusable if we are not able to build a correct
query plan for it.

A better solution here would be to deal with such unused variables
correctly, so that more introspection queries become reusable.

An even better solution would be to type-safely track *how* to reuse
which variables, rather than to split the reusage marking from the
planning.

* Don't compile in developer APIs by default

* 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.

* server/docs: add instructions to fix loss of float precision in PostgreSQL <= 11 (#5187)

This adds a server flag, --pg-connection-options, that can be used to set a PostgreSQL connection parameter, extra_float_digits, that needs to be used to avoid loss of data on older versions of PostgreSQL, which have odd default behavior when returning float values. (fixes #5092)

* Lower stack chunk size in RTS to reduce thread STACK memory (closes #5190)

This reduces memory consumption for new idle subscriptions significantly
(see linked ticket).

The hypothesis is: we fork a lot of threads per websocket, and some of
these use slightly more than the initial 1K stack size, so the first
overflow balloons to 32K, when significantly less is required.

However: running with `+RTS -K1K -xc` did not seem to show evidence of
any overflows! So it's a mystery why this improves things.

GHC should probably also be doubling the stack buffer at each overflow
or doing something even smarter; the knobs we have aren't so helpful.

These must have gotten messed up during a refactor. As a consequence
almost all samples received so far fall into the single erroneous 0 to

arbitrary and might want adjusting in the future.

!!! WARNING !!!
Since all fields accept `null`, they all are technically optional in
the new schema. Meaning there's no such thing as a missing mandatory
field anymore: a field that doesn't have a default value, and which
therefore isn't labelled as "optional" in the schema, will be assumed
to be null if it's missing, meaning it isn't possible anymore to have
an error for a missing mandatory field. The only possible error is now
when a optional positional argument is omitted but is not the last
positional argument.

* [skip ci] cleanup of int scalar parser

* [skip ci] retro-compatibility of offset as string

* [skip ci] Remove commit from commit_diff.txt

Although strictly speaking we don't know if this will work correctly in PDV
if we would implement query plan caching, the fact is that in the theoretical
case that we would have the same issue in PDV, it would probably apply not just
to introspection, and the fix would be written completely differently.  So this
old commit is of no value to us other than the heads-up "make sure query plan
caching works correctly even in the presence of unused variables", which is
already part of the test suite.

Just like object types, interface types, and union types, we have to avoid
circularities when collecting input types from the GraphQL AST.

Additionally, this fixes equality checks for input object types (whose fields
are unordered, and hence should be compared as sets) and enum types (ditto).

Also some minor refactoring of bounded cache module:

 - consequently trim was unnecessary for lookupPure

Also add some basic tests

We used to lookup the objects that implement a given interface by filtering all
objects in the schema document.  However, one of the tests expects us to
generate a warning if the provided `implements` field of an introspection query
specifies an object not implementing some interface.  So we use that field
instead.

* Delete code for "interfaces implementing ifaces" (draft GraphQL spec)

Previously I started writing some code that adds support for a future GraphQL
feature where interfaces may themselves be sub-types of other interfaces.
However, this code was incomplete, and partially incorrect.  So this commit
deletes support for that entirely.

* Ignore a remote schema test during the upgrade/downgrade test

The PDV refactor does a better job at exposing a minimal set of types through
introspection.  In particular, not every type that is present in a remote schema
is re-exposed by Hasura.  The test
test_schema_stitching.py::TestRemoteSchemaBasic::test_introspection assumed that
all types were re-exposed, which is not required for GraphQL compatibility, in
order to test some aspect of our support for remote schemas.

So while this particular test has been updated on PDV, the PDV branch now does
not pass the old test, which we argue to be incorrect.  Hence this test is
disabled while we await a release, after which we can re-enable it.

This also re-enables a test that was previously disabled for similar, though
unrelated, reasons.

* add haddock documentation to the action's field parsers

* Deslecting some tests in server-upgrade

Some tests with current build are failing on server upgrade
which it should not. The response is more accurate than
what it was.

Also the upgrade tests were not throwing errors when the test is
expected to return an error, but succeeds. The test framework is
patched to catch this case.

* Add bulldozer auto-merge and -update configuration

We still need to add the github app (as of time of opening this PR)

Afterwards devs should be able to allow bulldozer to automatically
"update" the branch, merging in parent when it changes, as well as
automatically merge when all checks pass.

This is opt-in by adding the `auto-update-auto-merge` label to the PR.

* Remove 'bulldozer' config, try 'kodiak' for auto-merge

see: https://github.com/chdsbd/kodiak

The main issue that bit us was not being able to auto update forked
branches, also:
https://github.com/palantir/bulldozer/issues/66

* changes for poller-log

add various multiplexed query info in poller-log

* minor cleanup, also fixes a bug which will return duplicate data

This also removes in-memory stats that are collected about batched
query execution as the log lines when piped into an monitoring tool
will give us better insights.

* allow poller-log to be configurable

* log minimal information in the livequery-poller-log

Other information can be retrieved from /dev/subscriptions/extended

* fix few review comments

* avoid marshalling and unmarshalling from ByteString to EncJSON

* separate out SubscriberId and SubscriberMetadata

exceptions we are now surfacing (see e.g. #4344)

The JSONPath parser is also rewritten, the previous implementation
was written in a very explicitly “recursive descent” style, but the whole
point of using attoparsec is to be able to backtrack! Taking advantage
of the combinators makes for a much simpler parser.

server(events): utilize proper backpressure scheme (close #3839) (#4013)
* Test working through a backlog of change events

* Use a slightly more performant threaded http server in eventing pytests

This helped locally but not on CI it seems...

* Rework event processing for backpressure. Closes #3839

With loo low `HASURA_GRAPHQL_EVENTS_FETCH_INTERVAL` and/or slow webhooks
and/or too small `HASURA_GRAPHQL_EVENTS_HTTP_POOL_SIZE` we might
previously check out events from the DB faster than we can service them,
leading to space leaks, weirdness, etc.

Other changes:
- avoid fetch interval sleep latency when we previously did a non-empty
  fetch
- prefetch event batch while http pool is working
- warn when it appears we can't keep up with events being generated
- make some effort to process events in creation order so we don't
  starve older ones.

ALSO NOTE: HASURA_GRAPHQL_EVENTS_FETCH_INTERVAL changes semantics
slightly, since it only comes into play after an empty fetch. The old
semantics weren't documented in detail, so I think this is fine.

8ef205fba5 Explicitly invalidate enum values when metadata is reloaded
This fixes #3759. Also, while we’re at it, also improve the way
invalidations are synced across instances so enums and remote schemas
are appropriately reloaded by the schema syncing process.

e47a8c4b86 incremental metadata: Clean up a few lingering loose ends
- Move MonadBase/MonadBaseControl instances for TxE into pg-client-hs
- Set the -qn2 RTS option by default to limit the parallel GC to 2
  threads
- Remove eventlog instrumentation
- Don’t rebuild the schema cache again after running a query that needs
  it to be rebuilt, since we do that explicitly now.
- Remove some redundant checks, and relocate a couple others.

d86a3d9501 Use fine(er)-grained dependency tracking when building permissions
This changes TableCoreCacheT to internally record dependencies at a
per-table level. In practice, this dramatically improves the performance
of building permissions: it makes it far, far less likely for
permissions to be needlessly rebuilt because some unrelated table
changed.

421a182f64 export metadata without nulls, empty arrays & default values (#3393)
* export metadata without nulls, empty arrays
* property tests for 'ReplaceMetadata' using QuickCheck
-> Derive Arbitrary class for 'ReplaceMetadata' dependant types

* reduce property test cases number to 30
QuickCheck generates the `ReplaceMetadata` value really large
for higher number test cases. Encoded JSON for such values is large and
consumes more memory. Thus, CI is giving up while running property
tests.

* circle-ci: Add property tests as saperate job
* add no command mode to tests
* add yaml.v2 to go mod
* remove indirect comment for yaml.v2 dependency
