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

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

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: {}
```

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

* 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.

* flush log buffer on exception in mkWaiApp ( fix #4772 ) (#4801)

* flush log buffer on exception in mkWaiApp

* add comment to explain the introduced change

* add changelog

* allow logging details of a live query polling thread (#4959)

* changes for poller-log

add various multiplexed query info in poller-log

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

* Live query poller stats can now be logged

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

* 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.

* [skip ci] fix todo and schema generation for aggregate fields

* update pg-client (#5421)

* [skip ci] update commit_diff

* Fix latency buckets for telemetry data

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
1K seconds (originally supposed to be 1ms?) bucket.

I also re-thought what the numbers should be, but these are still
arbitrary and might want adjusting in the future.

* [skip ci] include the latest commit compared against master in commit_diff

* [skip ci] include new commits from master in commit_diff

* [skip ci] improve description generation

* [skip ci] sort all introspect arrays

* [skip ci] allow parsers to specify error codes

* [skip ci] scalar from json errors are now parse errors

* [skip ci] fixed negative integer error message and code

* [skip ci] Re-fix nullability in relationships

* [skip ci] uncomment code in 'deleteMetadataObject'

* [skip ci] Fix re-fix of nullability for relationships

* [skip ci] fix default arguments error code

* [skip ci] updated test error message

!!! 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.

* Add MonadTrace and MonadExecuteQuery abstractions (#5383)

* [skip ci] Fix accumulation of input object types

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).

* [skip ci] update commit_diff with new commits added in master

* Bugfix to support 0-size HASURA_GRAPHQL_QUERY_PLAN_CACHE_SIZE

Also some minor refactoring of bounded cache module:
 - the maxBound check in `trim` was confusing and unnecessary
 - consequently trim was unnecessary for lookupPure

Also add some basic tests

* Support only the bounded cache, with default HASURA_GRAPHQL_QUERY_PLAN_CACHE_SIZE of 4000. Closes #5363

* Move nullableType/nonNullableType to Schema.hs

These are functions on Types, not on Parsers.

* [skip ci] fix setup to fix backend only test

the order in which permission checks are performed on the branch is
slightly different than on master, resulting in a slightly different
error if there are no other mutations the user has access to. By
adding update permissions, we go back to the expected case.

* [skip ci] Fix two warnings

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.

* fix 'ID' input coercing & action 'ID' type relationship mapping

* include ASTs in MonadExecuteQuery

* needed for PRO code-base

* 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
https://github.com/palantir/bulldozer/issues/145

* Cherry-picked all commits

* [skip ci] Slightly improve formatting

* Revert "fix introspection query if any enum column present in primary key (fix #5200) (#5522)"

This reverts commit 0f9a5afa59.

This undoes a cherry-pick of 34288e1eb5 that was
already done previously in a6450e126b, and
subsequently fixed for PDV in 70e89dc250

* Do a small bit of tidying in Hasura.GraphQL.Parser.Collect

* Fix cherry-picking work

Some previous cherry-picks ended up modifying code that is commented out

* [skip ci] clarified comment regarding insert representation

* [skip ci] removed obsolete todos

* cosmetic change

* fix action error message

* [skip ci] remove obsolete comment

* [skip ci] synchronize stylish haskell extensions list

* use previously defined scalar names in parsers rather than ad-hoc literals

* Apply most syntax hlint hints.

* Clarify comment on update mutation.

* [skip ci] Clarify what fields should be specified for objects

* Update "_inc" description.

* Use record types rather than tuples fo IntrospectionResult and ParsedIntrospection

* Get rid of checkFieldNamesUnique (use Data.List.Extended.duplicates)

* Throw more errors when collecting query root names

* [skip ci] clean column parser comment

* Remove dead code inserted in ab65b39

* avoid converting to non-empty list where not needed

* add note and TODO about the disabled checks in PDV

* minor refactor in remoteField' function

* Unify two getObject methods

* Nitpicks in Remote.hs

* Update CHANGELOG.md

* Revert "Unify two getObject methods"

This reverts commit bd6bb40355.

We do need two different getObject functions as the corresponding error message is different

* Fix error message in Remote.hs

* Update CHANGELOG.md

Co-authored-by: Auke Booij <auke@tulcod.com>

* Apply suggested Changelog fix.

Co-authored-by: Auke Booij <auke@tulcod.com>

* Fix typo in Changelog.

* [skip ci] Update changelog.

* reuse type names to avoid duplication

* Fix Hashable instance for Definition

The presence of `Maybe Unique`, and an optional description, as part of
`Definition`s, means that `Definition`s that are considered `Eq`ual may get
different hashes.  This can happen, for instance, when one object is memoized
but another is not.

* [skip ci] Update commit_diff.txt

* Bump parser version.

* Bump freeze file after changes in parser.

* [skip ci] Incorporate commits from master

* Fix developer flag in server/cabal.project.freeze

Co-authored-by: Auke Booij <auke@tulcod.com>

* Deselect a changed ENUM test for upgrade/downgrade CI

* Deselect test here as well

* [skip ci] remove dead code

* Disable more tests for upgrade/downgrade

* Fix which test gets deselected

* Revert "Add hdb_catalog.current_setting abstraction for reading Hasura settings"

This reverts commit 66e85ab9fb.

* Remove circular reference in cabal.project.freeze

Improve performance of replace_metadata on tracking tables. Closes #3802 (#4182)
* Improve performance of replace_metadata on tracking tables. Closes #3802

On the 1000 table track case this went from >20min to 8 seconds, the
bottleneck being all the former calls (for each table) to
buildSchemaCache.

* refactor replace metadata

Only save metadata in hdb_catalog schema and build schema cache (strictly)

* remove `withBuildSchemaCache` function

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.

* 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

4facb3c780 remove support for query templates (#2560)
query templates is a little known feature that lets you template rql
queries and serve them as rest apis. This is not relevant anymore
given the GraphQL interface and getting rid of it reduces the dev
time when adding features in few subsystems.

This feature has never been used outside hasura's internal projects or
documented or exposed through console and hence can safely be removed.
