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

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

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

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

661a1b6560 Remove source cache requirement in action schema
### Description

This PR removes the need for the `SourceCache` when building the schema for the actions. To do so, it changes the way we represent custom types in the source cache. Instead of trying to reuse the same `ObjectTypeDefinition` and `TypeRelationship`. we now have separate `AnnotatedObjectType` and `AnnotatedRelationship`. When building them, at schema cache building time, we persist all the relevant source information, so that it's all available at schema building time.

This PR makes no attempt at re-using `RemoteRelationship` primitives, to avoid having to change the way async action queries are executed, and to avoid having to make complicated changes to how we parse and represent those relationships.

e3c2bf53a5 Move, document, and prune action types and custom types types.
### Description

This PR is a first step in a series of cleanups of action relationships. This first step does not contain any behavioral change, and it simply reorganizes / prunes / rearranges / documents the code. Mainly:
- it divides some files in RQL.Types between metadata types, schema cache types, execution types;
- it renames some types for consistency;
- it minimizes exports and prunes unnecessary types;
- it moves some types in places where they make more sense;
- it replaces uses of `DMap BackendTag` with `BackendMap`.

Most of the "movement" within files re-organizes declarations in a "top-down" fashion, by moving all TH splices to the end of the file, which avoids order or declarations mattering.

### Optional list types

One main type change this PR makes is a replacement of variant list types in `CustomTypes.hs`; we had `Maybe [a]`, or sometimes `Maybe (NonEmpty a)`. This PR harmonizes all of them to `[a]`, as most of the code would use them as such, by doing `fromMaybe []` or `maybe [] toList`.

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.)

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

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.

* 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.

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.

arbitrary and might want adjusting in the future.

* [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).

* pass request body to logging context in all cases

* add message size logging on the websocket API

  this is required by graphql-engine-pro/#416

* message size logging on websocket API

  As we need to log all messages recieved/sent by the websocket server,
  it makes sense to log them as part of the websocket server event logs.
  Previously message recieved were logged inside the onMessage handler,
  and messages sent were logged only for "data" messages (as a server event log)

* [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

* [skip ci] remove merge commit from commit_diff

* server: Fix compiler warning caused by GHC upgrade (#5489)

Co-authored-by: Vamshi Surabhi <0x777@users.noreply.github.com>

* [skip ci] update all non server code from master

* [skip ci] aligned object field error message with master

* [skip ci] fix remaining undefined?

* [skip ci] remove unused import

* [skip ci] revert to previous error message, fix tests

* 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 insert geojson tests to reflect new paths

* [skip ci] fix enum test for better error message

* [skip ci] fix header test for better error message

* [skip ci] fix fragment cycle test for better error message

As the comment in the function’s definition explains, this is needed to
work around an awkward Postgres behavior.

* [skip ci] Update CONTRIBUTING.md to mention Node setup for Python tests

* [skip ci] Add missing Python tests env var to CONTRIBUTING.md

* [skip ci] fix order of result when subscription is run with multiple nodes

* [skip ci] no-op refactor: fix a warning in Internal/Parser.hs

* [skip ci] throw error when a subscription contains remote joins

* [skip ci] Enable easier profiling by hiding AssertNF behind a flag

In order to compile a profiling build, run:

$ cabal new-build -f profiling --enable-profiling

* [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.

* [skip ci] Fix warnings by commenting out query plan caching

* [skip ci] improve masking/commenting query caching related code & few warning fixes

* [skip ci] Fixed compiler warnings in graphql-parser-hs

* Sync non-Haskell assets with master

* [skip ci] add a test inserting invalid GraphQL but valid JSON value in a jsonb column

* fix backend test

* Simplify subscription execution

* [skip ci] add test to check if required headers are present while querying

* Suppose, table B is related to table A and to query B certain headers are
  necessary, then the test checks that we are throwing error when the header
  is not set when B is queried through A

* fix mutations not checking for view mutability

* [skip ci] add variable type checking and corresponding tests

* [skip ci] add test to check if update headers are present while doing an upsert

* use nullability of remote schema node, while creating a Remote reln

* 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.

* [skip ci] Add a long Note about interfaces and object types

* send the response headers back to client after running a query

* Deselect a few more tests during upgrade/downgrade test

* Update commit_diff.txt

* change log kind from db_migrate to catalog_migrate (#5531)

* 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 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.

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

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

Also: dev.sh: fix hpc reporting

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

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

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

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

Also...

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

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

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

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

We catch a bug in 'computeTimeDiff'.

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