0775c00b0d server: add validation for query collections

d50aae87a5 Updates cabal freeze file
#### TODO

- [x] fix `hashable >= 1.3.1` serialization ordering issue [^1]
  - `test_graphql_mutations.py::TestGraphQLMutateEnums` was failing
- [x] fix `unordered-containers` serialization ordering issue [^2]
  - `test_graphql_queries.py` was failing on Citus
- [ ] verify that no new failures have been introduced
- [ ] open issues to fix the above
  - identify test cases that "leak" implementation details by depending on `hashable` instance ordering
  - bump `hashable >= 1.3.1` and update test cases with new ordering OR modify them so that ordering is stable
  - bump `unordered-containers >= 0.2.15.0` and update test cases with new ordering OR modify them so that ordering is stable
    - one of the test cases was failing on string equality comparison for a generated Citus query
    - we probably don't want to _actually_ do this unless there are _very specific_ guarantees we want to make about generated query structure
---

Just what it says on the tin.

https://github.com/hasura/graphql-engine-mono/pull/3538 updated the freeze file a few weeks ago, but it looks like the index state hadn't been updated since December so a lot of stuff that had newer versions didn't get updated.

---

EDIT: I should add, the motivation for doing this in the first place is that `hspec > 2.8.4` now supports specifying filtering spec trees based on patterns provided by the `HSPEC_MATCH` environment variable.

For example, one could have a script that executes the following:
```
HSPEC_MATCH="PostgreSQL" \
  ghcid \
    --command \
      'cabal repl graphql-engine:test:tests-hspec \
         --repl-option -O0 \
         --repl-option -fobject-code' \
    --test "main"
```
...which will loop on typechecking the `tests-hspec` component, and then as soon as it passes (i.e. no warnings or errors) will run _only_ the `PostgreSQL` sub-components.

[^1]: `hashable >= 1.3.1.0` [updated its default salts](https://github.com/haskell-unordered-containers/hashable/pull/196), which [broke serialization ordering](https://github.com/haskell/aeson/issues/837)
[^2]: `unordered-containers >= 0.2.16.0` [introduced changes to some of its internal functions](https://hackage.haskell.org/package/unordered-containers-0.2.16.0/changelog) which seem like they could have affected serialization stability

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

a5589c185b Fix nullability of nested objrel inserts (fix )
### 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.

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.

904029aa7d Add fancier trace debugging functions to Hasura.Prelude
## Suggestion: Add fancier trace debugging functions to `Hasura.Prelude`

This PR adds two trace functions, `ltrace` and `ltraceM`, which use the `pretty-simple` package to `show` the input with nice formatting and colors for ease of reading (and comparing using diff tools such as `meld` or `vim-diff`).

I've also added warning pragmas to the functions, which means:
1. Traces will not be left in code, as CI builds with -Werror
2. Developers will have to change the `ghc-options` to `-Wwarn` in their `cabal.project.local` settings to use these functions

### Example

Usage:

```hs
selectFunctionAggregate ... = ... do
  ltraceM "functionInfo" function
  ...
```

Output to terminal looks like this:

<img width="524" alt="Screen Shot 2021-08-12 at 10 33 24" src="https://user-images.githubusercontent.com/8547573/129158878-4a5e96ba-30a5-452c-8f33-9eb4b2cc5e2a.png">

### Dependencies

Requires adding the following dependencies:
  - prettyprinter-ansi-terminal-1.1.2 (BSD2)
  - pretty-simple-4.0.0.0 (BSD3)

Question: what is the process for adding new dependencies? How does decisions on this matter happen?

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

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

* server: fix an introspection query caching issue (fix ) ()

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.

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

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.

!!! 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 ()

* [skip ci] Fix accumulation of input object types

Just like object types, interface types, and union types, we have to avoid

* 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

* [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.

* 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

* 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

* Fix Hashable instance for Definition

The presence of `Maybe Unique`, and an optional description, as part of

* Apply suggestions from code review

Co-Authored-By: Marion Schleifer <marion@hasura.io>

* improve doc for Postgres scalars in custom graphql types

* Add some more references to Note; fix Haddock syntax

Also a few very minor tweaks:
  * Use HashSet instead of [] more pervasively
  * Export execWriterT from Hasura.Prelude
  * Use pattern guards in multi-way if
  * Tweak a few names/comments

* Pull buildActions out of buildAndCollectInfo, use buildInfoMap

* Tweak wording in documentation

* incorporate changes in console code

* account Postgres scalars for action input arguments

-> Avoid unnecessary 'throw500' in making action schema

* Review changes

server: add support for webhook connection expiration ()
* add expiry time to webhook user info

This also adds an optional message to webhook errors: if we fail to
parse an expiry time, we will log a warning with the parse error.

* refactored Auth

This change had one main goal: put in common all expiry time
extraction code between the JWT and WebHook parts of the
code. Furthermore, this change also moves all WebHook specific code to
its own module, similarly to what is done for JWT.

* Remove dependency on string-conversions in favor of text-conversions

string-conversions silently uses UTF8 instead of being explicit about
it, and it uses lenientDecode when decoding ByteStrings when it’s
usually better to reject invalid UTF8 input outright. text-conversions
solves both those problems.

More robust forking, exception safety. Closes ()
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  for
Control.Concurrent.Extended

58ef316118 Add request timings and count histograms to telemetry. Closes
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  blocked on 

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.

421a182f64 export metadata without nulls, empty arrays & default values ()
* 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
