Rewrite OpenAPI
### Description This PR rewrites OpenAPI to be more idiomatic. Some noteworthy changes: - we accumulate all required information during the Analyze phase, to avoid having to do a single lookup in the schema cache during the OpenAPI generation phase (we now only need the schema cache as input to run the analysis) - we no longer build intermediary endpoint information and aggregate it, we directly build the the `PathItem` for each endpoint; additionally, that means we no longer have to assume that different methods have the same metadata - we no longer have to first declare types, then craft references: we do everything in one step - we now properly deal with nullability by treating "typeName" and "typeName!" as different - we add a bunch of additional fields in the generated "schema", such as title - we do now support enum values in both input and output positions - checking whether the request body is required is now performed on the fly rather than by introspecting the generated schema - the methods in the file are sorted by topic ### Controversial point However, this PR creates some additional complexity, that we might not want to keep. The main complexity is _knot-tying_: to avoid lookups when generating the OpenAPI, it builds an actual graph of input types, which means that we need something similar to (but simpler than) `MonadSchema`, to avoid infinite recursions when analyzing the input types of a query. To do this, this PR introduces `CircularT`, a lesser `SchemaT` that aims at avoiding ever having to reinvent this particular wheel ever again. ### Remaining work - [x] fix existing tests (they are all failing due to some of the schema changes) - [ ] add tests to cover the new features: - [x] tests for `CircularT` - [ ] tests for enums in output schemas - [x] extract / document `CircularT` if we wish to keep it - [x] add more comments to `OpenAPI` - [x] have a second look at `buildVariableSchema` - [x] fix all missing diagnostics in `Analyze` - [x] add a Changelog entry?

Remove Unique from Definition
GraphQL types can refer to each other in a circular way. The PDV framework used to use values of type `Unique` to recognize two fragments of GraphQL schema as being the same instance. Internally, this is based on `Data.Unique` from the `base` package, which simply increases a counter on every creation of a `Unique` object. **NB**: The `Unique` values are _not_ used for knot tying the schema combinators themselves (i.e. `Parser`s). The knot tying for `Parser`s is purely based on keys provided to `memoizeOn`. The `Unique` values are _only_ used to recognize two pieces of GraphQL _schema_ as being identical. Originally, the idea was that this would help us with a perfectly correct identification of GraphQL types. But this fully correct equality checking of GraphQL types was never implemented, and does not seem to be necessary to prevent bugs. Specifically, these `Unique` values are stored as part of `data Definition a`, which specifies a part of our internal abstract syntax tree for the GraphQL types that we expose. The `Unique` values get initialized by the `SchemaT` effect. In #2894 and #2895, we are experimenting with how (parts of) the GraphQL types can be hidden behind certain permission predicates. This would allow a single GraphQL schema in memory to serve all roles, implementing #2711. The permission predicates get evaluated at query parsing time when we know what role is doing a certain request, thus outputting the correct GraphQL types for that role. If the approach of #2895 is followed, then the `Definition` objects, and thus the `Unique` values, would be hidden behind the permission predicates. Since the permission predicates are evaluated only after the schema is already supposed to be built, this means that the permission predicates would prevent us from initializing the `Unique` values, rendering them useless. The simplest remedy to this is to remove our usage of `Unique` altogether from the GraphQL schema and schema combinators. It doesn't serve a functional purpose, doesn't prevent bugs, and requires extra bookkeeping.

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 https://github.com/hasura/graphql-engine-mono/pull/2404 GitOrigin-RevId: 75049f5c12f430c615eafb4c6b8e83e371e01c8e |

Server: Add Event Trigger Metrics
- [x] **Event Triggers Metrics**
- [x] Distribution of size of event trigger fetches / Number of events fetched in the last `event trigger fetch`
- [x] Event Triggers: Number of event trigger HTTP workers in process
- [x] Event Triggers: Avg event trigger lock time (if an event has been fetched but not processed because http worker is not free)
#### Sample response
The metrics can be viewed from the `/dev/ekg` endpoint
```json
{
"num_events_fetched":{
"max":0,
"mean":0,
"count":1,
"min":0,
"variance":null,
"type":"d",
"sum":0
},
"num_event_trigger_http_workers":{
"type":"g",
"val":0
},
"event_lock_time":{
"max":0,
"mean":0,
"count":0,
"min":0,
"variance":0,
"type":"d",
"sum":0
},
```
#### Todo
- [ ] Group similar metrics together (Eg: Group all the metrics related to Event trigger, How do we do it??)
Closes: https://github.com/hasura/graphql-engine-mono/issues/202

Rewrite GraphQL schema generation and query parsing (close #2801) (#4111)
Aka “the PDV refactor.” History is preserved on the branch 2801-graphql-schema-parser-refactor. * [skip ci] remove stale benchmark commit from commit_diff * [skip ci] Check for root field name conflicts between remotes * [skip ci] Additionally check for conflicts between remotes and DB * [skip ci] Check for conflicts in schema when tracking a table * [skip ci] Fix equality checking in GraphQL AST * server: fix mishandling of GeoJSON inputs in subscriptions (fix #3239) (#4551) * Add support for multiple top-level fields in a subscription to improve testability of subscriptions * Add an internal flag to enable multiple subscriptions * Add missing call to withConstructorFn in live queries (fix #3239) Co-authored-by: Alexis King <lexi.lambda@gmail.com> * Scheduled triggers (close #1914) (#3553) server: add scheduled triggers Co-authored-by: Alexis King <lexi.lambda@gmail.com> Co-authored-by: Marion Schleifer <marion@hasura.io> Co-authored-by: Karthikeyan Chinnakonda <karthikeyan@hasura.io> Co-authored-by: Aleksandra Sikora <ola.zxcvbnm@gmail.com> * 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. Co-authored-by: Tirumarai Selvan <tiru@hasura.io> * 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 Co-authored-by: Anon Ray <rayanon004@gmail.com> * 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. Referencing #4736 * 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) * [skip ci] Add new commits from master to the commit diff * [skip ci] serve default directives (skip & include) over introspection * [skip ci] Update non-Haskell assets with the version on master * server: refactor GQL execution check and config API (#5094) Co-authored-by: Vamshi Surabhi <vamshi@hasura.io> Co-authored-by: Vamshi Surabhi <0x777@users.noreply.github.com> * [skip ci] fix js issues in tests by pinning dependencies version * [skip ci] bump graphql version * [skip ci] Add note about memory usage * generalize query execution logic on Postgres (#5110) * generalize PGExecCtx to support specialized functions for various operations * fix tests compilation * allow customising PGExecCtx when starting the web server * server: changes catalog initialization and logging for pro customization (#5139) * new typeclass to abstract the logic of QueryLog-ing * abstract the logic of logging websocket-server logs introduce a MonadWSLog typeclass * move catalog initialization to init step expose a helper function to migrate catalog create schema cache in initialiseCtx * expose various modules and functions for pro * [skip ci] cosmetic change * [skip ci] fix test calling a mutation that does not exist * [skip ci] minor text change * [skip ci] refactored input values * [skip ci] remove VString Origin * server: fix updating of headers behaviour in the update cron trigger API and create future events immediately (#5151) * server: fix bug to update headers in an existing cron trigger and create future events Co-authored-by: Tirumarai Selvan <tiru@hasura.io> * 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 * 5087 libpq pool leak (#5089) Shrink libpq buffers to 1MB before returning connection to pool. Closes #5087 See: https://github.com/hasura/pg-client-hs/pull/19 Also related: #3388 #4077 * bump pg-client-hs version (fixes a build issue on some environments) (#5267) * do not use prepared statements for mutations * server: unlock scheduled events on graceful shutdown (#4928) * Fix buggy parsing of new --conn-lifetime flag in |
