Support nested object fields in DC API and use this to implement nest… ## Description This change adds support for nested object fields in HGE IR and Schema Cache, the Data Connectors backend and API, and the MongoDB agent. ### Data Connector API changes - The `/schema` endpoint response now includes an optional set of GraphQL type definitions. Table column types can refer to these definitions by name. - Queries can now include a new field type `object` which contains a column name and a nested query. This allows querying into a nested object within a field. ### MongoDB agent changes - Add support for querying into nested documents using the new `object` field type. ### HGE changes - The `Backend` type class has a new type family `XNestedObjects b` which controls whether or not a backend supports querying into nested objects. This is currently enabled only for the `DataConnector` backend. - For backends that support nested objects, the `FieldInfo` type gets a new constructor `FINestedObject`, and the `AnnFieldG` type gets a new constructor `AFNestedObject`. - If the DC `/schema` endpoint returns any custom GraphQL type definitions they are stored in the `TableInfo` for each table in the source. - During schema cache building, the function `addNonColumnFields` will check whether any column types match custom GraphQL object types stored in the `TableInfo`. If so, they are converted into `FINestedObject` instead of `FIColumn` in the `FieldInfoMap`. - When building the `FieldParser`s from `FieldInfo` (function `fieldSelection`) any `FINestedObject` fields are converted into nested object parsers returning `AFNestedObject`. - The `DataConnector` query planner converts `AFNestedObject` fields into `object` field types in the query sent to the agent. ## Limitations ### HGE not yet implemented: - Support for nested arrays - Support for nested objects/arrays in mutations - Support for nested objects/arrays in order-by - Support for filters (`where`) in nested objects/arrays - Support for adding custom GraphQL types via track table metadata API - Support for interface and union types - Tests for nested objects ### Mongo agent not yet implemented: - Generate nested object types from validation schema - Support for aggregates - Support for order-by - Configure agent port - Build agent in CI - Agent tests for nested objects and MongoDB agent PR-URL: https://github.com/hasura/graphql-engine-mono/pull/7844 GitOrigin-RevId: aec9ec1e4216293286a68f9b1af6f3f5317db423

Role-invariant schema constructors We build the GraphQL schema by combining building blocks such as `tableSelectionSet` and `columnParser`. These building blocks individually build `{InputFields,Field,}Parser` objects. Those object specify the valid GraphQL schema. Since the GraphQL schema is role-dependent, at some point we need to know what fragment of the GraphQL schema a specific role is allowed to access, and this is stored in `{Sel,Upd,Ins,Del}PermInfo` objects. We have passed around these permission objects as function arguments to the schema building blocks since we first started dealing with permissions during the PDV refactor - see hasura/graphql-engine@5168b99e463199b1934d8645bd6cd37eddb64ae1 in hasura/graphql-engine#4111. This means that, for instance, `tableSelectionSet` has as its type: ```haskell tableSelectionSet :: forall b r m n. MonadBuildSchema b r m n => SourceName -> TableInfo b -> SelPermInfo b -> m (Parser 'Output n (AnnotatedFields b)) ``` There are three reasons to change this. 1. We often pass a `Maybe (xPermInfo b)` instead of a proper `xPermInfo b`, and it's not clear what the intended semantics of this is. Some potential improvements on the data types involved are discussed in issue hasura/graphql-engine-mono#3125. 2. In most cases we also already pass a `TableInfo b`, and together with the `MonadRole` that is usually also in scope, this means that we could look up the required permissions regardless: so passing the permissions explicitly undermines the "single source of truth" principle. Breaking this principle also makes the code more difficult to read. 3. We are working towards role-based parsers (see hasura/graphql-engine-mono#2711), where the `{InputFields,Field,}Parser` objects are constructed in a role-invariant way, so that we have a single object that can be used for all roles. In particular, this means that the schema building blocks _need_ to be constructed in a role-invariant way. While this PR doesn't accomplish that, it does reduce the amount of role-specific arguments being passed, thus fixing hasura/graphql-engine-mono#3068. Concretely, this PR simply drops the `xPermInfo b` argument from almost all schema building blocks. Instead these objects are looked up from the `TableInfo b` as-needed. The resulting code is considerably simpler and shorter. One way to interpret this change is as follows. Before this PR, we figured out permissions at the top-level in `Hasura.GraphQL.Schema`, passing down the obtained `xPermInfo` objects as required. After this PR, we have a bottom-up approach where the schema building blocks themselves decide whether they want to be included for a particular role. So this moves some permission logic out of `Hasura.GraphQL.Schema`, which is very complex.

Support nested object fields in DC API and use this to implement nest… ## Description This change adds support for nested object fields in HGE IR and Schema Cache, the Data Connectors backend and API, and the MongoDB agent. ### Data Connector API changes - The `/schema` endpoint response now includes an optional set of GraphQL type definitions. Table column types can refer to these definitions by name. - Queries can now include a new field type `object` which contains a column name and a nested query. This allows querying into a nested object within a field. ### MongoDB agent changes - Add support for querying into nested documents using the new `object` field type. ### HGE changes - The `Backend` type class has a new type family `XNestedObjects b` which controls whether or not a backend supports querying into nested objects. This is currently enabled only for the `DataConnector` backend. - For backends that support nested objects, the `FieldInfo` type gets a new constructor `FINestedObject`, and the `AnnFieldG` type gets a new constructor `AFNestedObject`. - If the DC `/schema` endpoint returns any custom GraphQL type definitions they are stored in the `TableInfo` for each table in the source. - During schema cache building, the function `addNonColumnFields` will check whether any column types match custom GraphQL object types stored in the `TableInfo`. If so, they are converted into `FINestedObject` instead of `FIColumn` in the `FieldInfoMap`. - When building the `FieldParser`s from `FieldInfo` (function `fieldSelection`) any `FINestedObject` fields are converted into nested object parsers returning `AFNestedObject`. - The `DataConnector` query planner converts `AFNestedObject` fields into `object` field types in the query sent to the agent. ## Limitations ### HGE not yet implemented: - Support for nested arrays - Support for nested objects/arrays in mutations - Support for nested objects/arrays in order-by - Support for filters (`where`) in nested objects/arrays - Support for adding custom GraphQL types via track table metadata API - Support for interface and union types - Tests for nested objects ### Mongo agent not yet implemented: - Generate nested object types from validation schema - Support for aggregates - Support for order-by - Configure agent port - Build agent in CI - Agent tests for nested objects and MongoDB agent PR-URL: https://github.com/hasura/graphql-engine-mono/pull/7844 GitOrigin-RevId: aec9ec1e4216293286a68f9b1af6f3f5317db423

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 2b0e3774 * [skip ci] remove cherry-picked commit from commit_diff.txt * server: include additional fields in scheduled trigger webhook payload (#5262) * include scheduled triggers metadata in the webhook body Co-authored-by: Tirumarai Selvan <tiru@hasura.io> * server: call the webhook asynchronously in event triggers (#5352) * server: call the webhook asynchronosly in event triggers * Expose all modules in Cabal file (#5371) * [skip ci] update commit_diff.txt * [skip ci] fix cast exp parser & few TODOs * [skip ci] fix remote fields arguments * [skip ci] fix few more TODO, no-op refactor, move resolve/action.hs to execute/action.hs * Pass environment variables around as a data structure, via @sordina (#5374) * Pass environment variables around as a data structure, via @sordina * Resolving build error * Adding Environment passing note to changelog * Removing references to ILTPollerLog as this seems to have been reintroduced from a bad merge * removing commented-out imports * Language pragmas already set by project * Linking async thread * Apply suggestions from code review Use `runQueryTx` instead of `runLazyTx` for queries. * remove the non-user facing entry in the changelog Co-authored-by: Phil Freeman <paf31@cantab.net> Co-authored-by: Phil Freeman <phil@hasura.io> Co-authored-by: Vamshi Surabhi <0x777@users.noreply.github.com> * [skip ci] fix: restrict remote relationship field generation for hasura queries * [skip ci] no-op refactor; move insert execution code from schema parser module * server: call the webhook asynchronously in event triggers (#5352) * server: call the webhook asynchronosly in event triggers * Expose all modules in Cabal file (#5371) * [skip ci] update commit_diff.txt * Pass environment variables around as a data structure, via @sordina (#5374) * Pass environment variables around as a data structure, via @sordina * Resolving build error * Adding Environment passing note to changelog * Removing references to ILTPollerLog as this seems to have been reintroduced from a bad merge * removing commented-out imports * Language pragmas already set by project * Linking async thread * Apply suggestions from code review Use `runQueryTx` instead of `runLazyTx` for queries. * remove the non-user facing entry in the changelog Co-authored-by: Phil Freeman <paf31@cantab.net> Co-authored-by: Phil Freeman <phil@hasura.io> Co-authored-by: Vamshi Surabhi <0x777@users.noreply.github.com> * [skip ci] implement header checking Probably closes #14 and #3659. * server: refactor 'pollQuery' to have a hook to process 'PollDetails' (#5391) Co-authored-by: Vamshi Surabhi <0x777@users.noreply.github.com> * 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] fix integer and float parsing error code * [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] no-op refactor and removed couple of FIXMEs * [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] fix fragment error path * [skip ci] fix node error code * [skip ci] fix paths in insert queries * [skip ci] fix path in objects * [skip ci] manually alter node id path for consistency * [skip ci] more node error fixups * [skip ci] one last relay error message fix * [skip ci] update commit_diff * Propagate the trace context to event triggers (#5409) * Propagate the trace context to event triggers * Handle missing trace and span IDs * Store trace context as one LOCAL * Add migrations * Documentation * changelog * Fix warnings * Respond to code review suggestions * Respond to code review * Undo changelog * Update CHANGELOG.md Co-authored-by: Vamshi Surabhi <0x777@users.noreply.github.com> * server: log request/response sizes for event triggers (#5463) * server: log request/response sizes for event triggers event triggers (and scheduled triggers) now have request/response size in their logs. * add changelog entry * Tracing: Simplify HTTP traced request (#5451) Remove the Inversion of Control (SuspendRequest) and simplify the tracing of HTTP Requests.

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 * [skip ci] Avoid converting to/from Map * [skip ci] Apply some hlint suggestions * [skip ci] remove redundant constraints from buildLiveQueryPlan and explainGQLQuery * [skip ci] add NOTEs about missing Tracing constraints in PDV from master * Remove -fdefer-typed-holes, fix warnings * Update cabal.project.freeze * Limit GHC’s heap size to 8GB in CI to avoid the OOM killer * Commit package-lock.json for Python tests’ remote schema server * restrict env variables start with HASURA_GRAPHQL_ for headers configuration in actions, event triggers & remote schemas (#5519) * restrict env variables start with HASURA_GRAPHQL_ for headers definition in actions & event triggers * update CHANGELOG.md * Apply suggestions from code review Co-authored-by: Vamshi Surabhi <0x777@users.noreply.github.com> * add test for table_by_pk node when roles doesn't have permission to PK * [skip ci] fix introspection query if any enum column present in primary key (fix #5200) (#5522) * [skip ci] test case fix for a6450e126bc2d98bcfd3791501986e4627ce6c6f * [skip ci] add tests to agg queries when role doesn't have access to any cols * 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 * [skip ci] add positive counterparts to some of the negative permission tests * fix args missing their description in introspect * [skip ci] Remove unused function; insert missing markNotReusable call * [skip ci] Add a Note about InputValue * [skip ci] Delete LegacySchema/ 🎉 * [skip ci] Delete GraphQL/{Resolve,Validate}/ 🎉 * [skip ci] Delete top-level Resolve/Validate modules; tidy .cabal file * [skip ci] Delete LegacySchema top-level module Somehow I missed this one. * fix input value to json * [skip ci] elaborate on JSON objects in GraphQL * [skip ci] add missing file * [skip ci] add a test with subscription containing remote joins * add a test with remote joins in mutation output * [skip ci] Add some comments to Schema/Mutation.hs * [skip ci] Remove no longer needed code from RemoteServer.hs * [skip ci] Use a helper function to generate conflict clause parsers * [skip ci] fix type checker error in fields with default value * capitalize the header keys in select_articles_without_required_headers * Somehow, this was the reason the tests were failing.

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) * Show method and complete URI in traced HTTP calls (#5525) Co-authored-by: Vamshi Surabhi <0x777@users.noreply.github.com> * restrict env variables start with HASURA_GRAPHQL_ for headers configuration in actions, event triggers & remote schemas (#5519) * restrict env variables start with HASURA_GRAPHQL_ for headers definition in actions & event triggers * update CHANGELOG.md * Apply suggestions from code review Co-authored-by: Vamshi Surabhi <0x777@users.noreply.github.com> * fix introspection query if any enum column present in primary key (fix #5200) (#5522) * Fix telemetry reporting of transport (websocket was reported as http) * add log kinds in cli-migrations image (#5529) * add log kinds in cli-migrations image * give hint to resolve timeout error * minor changes and CHANGELOG * server: set hasura.tracecontext in RQL mutations [#5542] (#5555) * server: set hasura.tracecontext in RQL mutations [#5542] * Update test suite Co-authored-by: Tirumarai Selvan <tiru@hasura.io> * 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 0f9a5afa59a88f6824f4d63d58db246a5ba3fb03. This undoes a cherry-pick of 34288e1eb5f2c5dad9e6d1e05453dd52397dc970 that was already done previously in a6450e126bc2d98bcfd3791501986e4627ce6c6f, and subsequently fixed for PDV in 70e89dc250f8ddc6e2b7930bbe2b3eeaa6dbe1db * 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 bd6bb40355b3d189a46c0312eb52225e18be57b3.

Nested array support for Data Connectors Backend and MongoDB ## Description This change adds support for querying into nested arrays in Data Connector agents that support such a concept (currently MongoDB). ### DC API changes - New API type `ColumnType` which allows representing the type of a "column" as either a scalar type, an object reference or an array of `ColumnType`s. This recursive definition allows arbitrary nesting of arrays of types. - The `type` fields in the API types `ColumnInfo` and `ColumnInsertSchema` now take a `ColumnType` instead of a `ScalarType`. - To ensure backwards compatibility, a `ColumnType` representing a scalar serialises and deserialises to the same representation as `ScalarType`. - In queries, the `Field` type now has a new constructor `NestedArrayField`. This contains a nested `Field` along with optional `limit`, `offset`, `where` and `order_by` arguments. (These optional arguments are not yet used by either HGE or the MongoDB agent.) ### MongoDB Haskell agent changes - The `/schema` endpoint will now recognise arrays within the JSON validation schema and generate corresponding arrays in the DC schema. - The `/query` endpoint will now handle `NestedArrayField`s within queries (although it does not yet handle `limit`, `offset`, `where` and `order_by`). ### HGE server changes - The `Backend` type class adds a new type family `XNestedArrays b` to enable nested arrays on a per-backend basis (currently enabled only for the `DataConnector` backend. - Within `RawColumnInfo` the column type is now represented by a new type `RawColumnType b` which mirrors the shape of the DC API `ColumnType`, but uses `XNestedObjects b` and `XNestedArrays b` type families to allow turning nested object and array supports on or off for a particular backend. In the `DataConnector` backend `API.CustomType` is converted into `RawColumnInfo 'DataConnector` while building the schema. - In the next stage of schema building, the `RawColumnInfo` is converted into a `StructuredColumnInfo` which allows us to represent the three different types of columns: scalar, object and array. TODO: the `StructuredColumnInfo` looks very similar to the Logical Model types. The main difference is that it uses the `XNestedObjects` and `XNestedArrays` type families. We should be able to combine these two representations. - The `StructuredColumnInfo` is then placed into a `FIColumn` `FieldInfo`. This involved some refactoring of `FieldInfo` as I had previously split out `FINestedObject` into a separate constructor. However it works out better to represent all "column" fields (i.e. scalar, object and array) using `FIColumn` as this make it easier to implement permission checking correctly. This is the reason the `StructuredColumnInfo` was needed. - Next, the `FieldInfo` are used to generate `FieldParser`s. We add a new constructor to `AnnFieldG` for `AFNestedArray`. An `AFNestedArray` field parser can contain either a simple array selection or an array aggregate. Simple array `FieldParsers` are currently limited to subfield selection. We will add support for limit, offset, where and order_by in a future PR. We also don't yet generate array aggregate `FieldParsers. - The new `AFNestedArray` field is handled by the `QueryPlan` module in the `DataConnector` backend. There we generate an `API.NestedArrayField` from the AFNestedArray. We also handle nested arrays when reshaping the response from the DC agent. ## Limitations - Support for limit, offset, filter (where) and order_by is not yet fully implemented, although it should not be hard to add this - Support for aggregations on nested arrays is not yet fully implemented - Permissions involving nested arrays (and objects) not yet implemented - This should be integrated with Logical Model types, but that will happen in a separate PR PR-URL: https://github.com/hasura/graphql-engine-mono/pull/9149 GitOrigin-RevId: 0e7b71a994fc1d2ca1ef73bfe7b96e95b5328531

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 2b0e3774 * [skip ci] remove cherry-picked commit from commit_diff.txt * server: include additional fields in scheduled trigger webhook payload (#5262) * include scheduled triggers metadata in the webhook body Co-authored-by: Tirumarai Selvan <tiru@hasura.io> * server: call the webhook asynchronously in event triggers (#5352) * server: call the webhook asynchronosly in event triggers * Expose all modules in Cabal file (#5371) * [skip ci] update commit_diff.txt * [skip ci] fix cast exp parser & few TODOs * [skip ci] fix remote fields arguments * [skip ci] fix few more TODO, no-op refactor, move resolve/action.hs to execute/action.hs * Pass environment variables around as a data structure, via @sordina (#5374) * Pass environment variables around as a data structure, via @sordina * Resolving build error * Adding Environment passing note to changelog * Removing references to ILTPollerLog as this seems to have been reintroduced from a bad merge * removing commented-out imports * Language pragmas already set by project * Linking async thread * Apply suggestions from code review Use `runQueryTx` instead of `runLazyTx` for queries. * remove the non-user facing entry in the changelog Co-authored-by: Phil Freeman <paf31@cantab.net> Co-authored-by: Phil Freeman <phil@hasura.io> Co-authored-by: Vamshi Surabhi <0x777@users.noreply.github.com> * [skip ci] fix: restrict remote relationship field generation for hasura queries * [skip ci] no-op refactor; move insert execution code from schema parser module * server: call the webhook asynchronously in event triggers (#5352) * server: call the webhook asynchronosly in event triggers * Expose all modules in Cabal file (#5371) * [skip ci] update commit_diff.txt * Pass environment variables around as a data structure, via @sordina (#5374) * Pass environment variables around as a data structure, via @sordina * Resolving build error * Adding Environment passing note to changelog * Removing references to ILTPollerLog as this seems to have been reintroduced from a bad merge * removing commented-out imports * Language pragmas already set by project * Linking async thread * Apply suggestions from code review Use `runQueryTx` instead of `runLazyTx` for queries. * remove the non-user facing entry in the changelog Co-authored-by: Phil Freeman <paf31@cantab.net> Co-authored-by: Phil Freeman <phil@hasura.io> Co-authored-by: Vamshi Surabhi <0x777@users.noreply.github.com> * [skip ci] implement header checking Probably closes #14 and #3659. * server: refactor 'pollQuery' to have a hook to process 'PollDetails' (#5391) Co-authored-by: Vamshi Surabhi <0x777@users.noreply.github.com> * 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] fix integer and float parsing error code * [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] no-op refactor and removed couple of FIXMEs * [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.

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.

Nested array support for Data Connectors Backend and MongoDB ## Description This change adds support for querying into nested arrays in Data Connector agents that support such a concept (currently MongoDB). ### DC API changes - New API type `ColumnType` which allows representing the type of a "column" as either a scalar type, an object reference or an array of `ColumnType`s. This recursive definition allows arbitrary nesting of arrays of types. - The `type` fields in the API types `ColumnInfo` and `ColumnInsertSchema` now take a `ColumnType` instead of a `ScalarType`. - To ensure backwards compatibility, a `ColumnType` representing a scalar serialises and deserialises to the same representation as `ScalarType`. - In queries, the `Field` type now has a new constructor `NestedArrayField`. This contains a nested `Field` along with optional `limit`, `offset`, `where` and `order_by` arguments. (These optional arguments are not yet used by either HGE or the MongoDB agent.) ### MongoDB Haskell agent changes - The `/schema` endpoint will now recognise arrays within the JSON validation schema and generate corresponding arrays in the DC schema. - The `/query` endpoint will now handle `NestedArrayField`s within queries (although it does not yet handle `limit`, `offset`, `where` and `order_by`). ### HGE server changes - The `Backend` type class adds a new type family `XNestedArrays b` to enable nested arrays on a per-backend basis (currently enabled only for the `DataConnector` backend. - Within `RawColumnInfo` the column type is now represented by a new type `RawColumnType b` which mirrors the shape of the DC API `ColumnType`, but uses `XNestedObjects b` and `XNestedArrays b` type families to allow turning nested object and array supports on or off for a particular backend. In the `DataConnector` backend `API.CustomType` is converted into `RawColumnInfo 'DataConnector` while building the schema. - In the next stage of schema building, the `RawColumnInfo` is converted into a `StructuredColumnInfo` which allows us to represent the three different types of columns: scalar, object and array. TODO: the `StructuredColumnInfo` looks very similar to the Logical Model types. The main difference is that it uses the `XNestedObjects` and `XNestedArrays` type families. We should be able to combine these two representations. - The `StructuredColumnInfo` is then placed into a `FIColumn` `FieldInfo`. This involved some refactoring of `FieldInfo` as I had previously split out `FINestedObject` into a separate constructor. However it works out better to represent all "column" fields (i.e. scalar, object and array) using `FIColumn` as this make it easier to implement permission checking correctly. This is the reason the `StructuredColumnInfo` was needed. - Next, the `FieldInfo` are used to generate `FieldParser`s. We add a new constructor to `AnnFieldG` for `AFNestedArray`. An `AFNestedArray` field parser can contain either a simple array selection or an array aggregate. Simple array `FieldParsers` are currently limited to subfield selection. We will add support for limit, offset, where and order_by in a future PR. We also don't yet generate array aggregate `FieldParsers. - The new `AFNestedArray` field is handled by the `QueryPlan` module in the `DataConnector` backend. There we generate an `API.NestedArrayField` from the AFNestedArray. We also handle nested arrays when reshaping the response from the DC agent. ## Limitations - Support for limit, offset, filter (where) and order_by is not yet fully implemented, although it should not be hard to add this - Support for aggregations on nested arrays is not yet fully implemented - Permissions involving nested arrays (and objects) not yet implemented - This should be integrated with Logical Model types, but that will happen in a separate PR PR-URL: https://github.com/hasura/graphql-engine-mono/pull/9149 GitOrigin-RevId: 0e7b71a994fc1d2ca1ef73bfe7b96e95b5328531

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.

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.

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.

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] fix fragment error path * [skip ci] fix node error code * [skip ci] fix paths in insert queries * [skip ci] fix path in objects * [skip ci] manually alter node id path for consistency * [skip ci] more node error fixups * [skip ci] one last relay error message fix * [skip ci] update commit_diff * Propagate the trace context to event triggers (#5409) * Propagate the trace context to event triggers * Handle missing trace and span IDs * Store trace context as one LOCAL * Add migrations * Documentation * changelog * Fix warnings * Respond to code review suggestions * Respond to code review * Undo changelog * Update CHANGELOG.md Co-authored-by: Vamshi Surabhi <0x777@users.noreply.github.com> * server: log request/response sizes for event triggers (#5463) * server: log request/response sizes for event triggers event triggers (and scheduled triggers) now have request/response size in their logs. * add changelog entry * Tracing: Simplify HTTP traced request (#5451) Remove the Inversion of Control (SuspendRequest) and simplify the tracing of HTTP Requests.

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 * [skip ci] Avoid converting to/from Map * [skip ci] Apply some hlint suggestions * [skip ci] remove redundant constraints from buildLiveQueryPlan and explainGQLQuery * [skip ci] add NOTEs about missing Tracing constraints in PDV from master * Remove -fdefer-typed-holes, fix warnings * Update cabal.project.freeze * Limit GHC’s heap size to 8GB in CI to avoid the OOM killer * Commit package-lock.json for Python tests’ remote schema server * restrict env variables start with HASURA_GRAPHQL_ for headers configuration in actions, event triggers & remote schemas (#5519) * restrict env variables start with HASURA_GRAPHQL_ for headers definition in actions & event triggers * update CHANGELOG.md * Apply suggestions from code review Co-authored-by: Vamshi Surabhi <0x777@users.noreply.github.com> * add test for table_by_pk node when roles doesn't have permission to PK * [skip ci] fix introspection query if any enum column present in primary key (fix #5200) (#5522) * [skip ci] test case fix for a6450e126bc2d98bcfd3791501986e4627ce6c6f * [skip ci] add tests to agg queries when role doesn't have access to any cols * 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 * [skip ci] add positive counterparts to some of the negative permission tests * fix args missing their description in introspect * [skip ci] Remove unused function; insert missing markNotReusable call * [skip ci] Add a Note about InputValue * [skip ci] Delete LegacySchema/ 🎉 * [skip ci] Delete GraphQL/{Resolve,Validate}/ 🎉 * [skip ci] Delete top-level Resolve/Validate modules; tidy .cabal file * [skip ci] Delete LegacySchema top-level module Somehow I missed this one. * fix input value to json * [skip ci] elaborate on JSON objects in GraphQL * [skip ci] add missing file * [skip ci] add a test with subscription containing remote joins * add a test with remote joins in mutation output * [skip ci] Add some comments to Schema/Mutation.hs * [skip ci] Remove no longer needed code from RemoteServer.hs * [skip ci] Use a helper function to generate conflict clause parsers * [skip ci] fix type checker error in fields with default value * capitalize the header keys in select_articles_without_required_headers * Somehow, this was the reason the tests were failing.

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) * Show method and complete URI in traced HTTP calls (#5525) Co-authored-by: Vamshi Surabhi <0x777@users.noreply.github.com> * restrict env variables start with HASURA_GRAPHQL_ for headers configuration in actions, event triggers & remote schemas (#5519) * restrict env variables start with HASURA_GRAPHQL_ for headers definition in actions & event triggers * update CHANGELOG.md * Apply suggestions from code review Co-authored-by: Vamshi Surabhi <0x777@users.noreply.github.com> * fix introspection query if any enum column present in primary key (fix #5200) (#5522) * Fix telemetry reporting of transport (websocket was reported as http) * add log kinds in cli-migrations image (#5529) * add log kinds in cli-migrations image * give hint to resolve timeout error * minor changes and CHANGELOG * server: set hasura.tracecontext in RQL mutations [#5542] (#5555) * server: set hasura.tracecontext in RQL mutations [#5542] * Update test suite Co-authored-by: Tirumarai Selvan <tiru@hasura.io> * 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 0f9a5afa59a88f6824f4d63d58db246a5ba3fb03. This undoes a cherry-pick of 34288e1eb5f2c5dad9e6d1e05453dd52397dc970 that was already done previously in a6450e126bc2d98bcfd3791501986e4627ce6c6f, and subsequently fixed for PDV in 70e89dc250f8ddc6e2b7930bbe2b3eeaa6dbe1db * 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 bd6bb40355b3d189a46c0312eb52225e18be57b3.

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.

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.

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] fix fragment error path * [skip ci] fix node error code * [skip ci] fix paths in insert queries * [skip ci] fix path in objects * [skip ci] manually alter node id path for consistency * [skip ci] more node error fixups * [skip ci] one last relay error message fix * [skip ci] update commit_diff * Propagate the trace context to event triggers (#5409) * Propagate the trace context to event triggers * Handle missing trace and span IDs * Store trace context as one LOCAL * Add migrations * Documentation * changelog * Fix warnings * Respond to code review suggestions * Respond to code review * Undo changelog * Update CHANGELOG.md Co-authored-by: Vamshi Surabhi <0x777@users.noreply.github.com> * server: log request/response sizes for event triggers (#5463) * server: log request/response sizes for event triggers event triggers (and scheduled triggers) now have request/response size in their logs. * add changelog entry * Tracing: Simplify HTTP traced request (#5451) Remove the Inversion of Control (SuspendRequest) and simplify the tracing of HTTP Requests.

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) * Show method and complete URI in traced HTTP calls (#5525) Co-authored-by: Vamshi Surabhi <0x777@users.noreply.github.com> * restrict env variables start with HASURA_GRAPHQL_ for headers configuration in actions, event triggers & remote schemas (#5519) * restrict env variables start with HASURA_GRAPHQL_ for headers definition in actions & event triggers * update CHANGELOG.md * Apply suggestions from code review Co-authored-by: Vamshi Surabhi <0x777@users.noreply.github.com> * fix introspection query if any enum column present in primary key (fix #5200) (#5522) * Fix telemetry reporting of transport (websocket was reported as http) * add log kinds in cli-migrations image (#5529) * add log kinds in cli-migrations image * give hint to resolve timeout error * minor changes and CHANGELOG * server: set hasura.tracecontext in RQL mutations [#5542] (#5555) * server: set hasura.tracecontext in RQL mutations [#5542] * Update test suite Co-authored-by: Tirumarai Selvan <tiru@hasura.io> * 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 0f9a5afa59a88f6824f4d63d58db246a5ba3fb03.

ObjRel -> [name]
Nested array support for Data Connectors Backend and MongoDB ## Description This change adds support for querying into nested arrays in Data Connector agents that support such a concept (currently MongoDB). ### DC API changes - New API type `ColumnType` which allows representing the type of a "column" as either a scalar type, an object reference or an array of `ColumnType`s. This recursive definition allows arbitrary nesting of arrays of types. - The `type` fields in the API types `ColumnInfo` and `ColumnInsertSchema` now take a `ColumnType` instead of a `ScalarType`. - To ensure backwards compatibility, a `ColumnType` representing a scalar serialises and deserialises to the same representation as `ScalarType`. - In queries, the `Field` type now has a new constructor `NestedArrayField`. This contains a nested `Field` along with optional `limit`, `offset`, `where` and `order_by` arguments. (These optional arguments are not yet used by either HGE or the MongoDB agent.) ### MongoDB Haskell agent changes - The `/schema` endpoint will now recognise arrays within the JSON validation schema and generate corresponding arrays in the DC schema. - The `/query` endpoint will now handle `NestedArrayField`s within queries (although it does not yet handle `limit`, `offset`, `where` and `order_by`). ### HGE server changes - The `Backend` type class adds a new type family `XNestedArrays b` to enable nested arrays on a per-backend basis (currently enabled only for the `DataConnector` backend. - Within `RawColumnInfo` the column type is now represented by a new type `RawColumnType b` which mirrors the shape of the DC API `ColumnType`, but uses `XNestedObjects b` and `XNestedArrays b` type families to allow turning nested object and array supports on or off for a particular backend. In the `DataConnector` backend `API.CustomType` is converted into `RawColumnInfo 'DataConnector` while building the schema. - In the next stage of schema building, the `RawColumnInfo` is converted into a `StructuredColumnInfo` which allows us to represent the three different types of columns: scalar, object and array. TODO: the `StructuredColumnInfo` looks very similar to the Logical Model types. The main difference is that it uses the `XNestedObjects` and `XNestedArrays` type families. We should be able to combine these two representations. - The `StructuredColumnInfo` is then placed into a `FIColumn` `FieldInfo`. This involved some refactoring of `FieldInfo` as I had previously split out `FINestedObject` into a separate constructor. However it works out better to represent all "column" fields (i.e. scalar, object and array) using `FIColumn` as this make it easier to implement permission checking correctly. This is the reason the `StructuredColumnInfo` was needed. - Next, the `FieldInfo` are used to generate `FieldParser`s. We add a new constructor to `AnnFieldG` for `AFNestedArray`. An `AFNestedArray` field parser can contain either a simple array selection or an array aggregate. Simple array `FieldParsers` are currently limited to subfield selection. We will add support for limit, offset, where and order_by in a future PR. We also don't yet generate array aggregate `FieldParsers. - The new `AFNestedArray` field is handled by the `QueryPlan` module in the `DataConnector` backend. There we generate an `API.NestedArrayField` from the AFNestedArray. We also handle nested arrays when reshaping the response from the DC agent. ## Limitations - Support for limit, offset, filter (where) and order_by is not yet fully implemented, although it should not be hard to add this - Support for aggregations on nested arrays is not yet fully implemented - Permissions involving nested arrays (and objects) not yet implemented - This should be integrated with Logical Model types, but that will happen in a separate PR PR-URL: https://github.com/hasura/graphql-engine-mono/pull/9149 GitOrigin-RevId: 0e7b71a994fc1d2ca1ef73bfe7b96e95b5328531

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.

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.

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.

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.

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) * Show method and complete URI in traced HTTP calls (#5525) Co-authored-by: Vamshi Surabhi <0x777@users.noreply.github.com> * restrict env variables start with HASURA_GRAPHQL_ for headers configuration in actions, event triggers & remote schemas (#5519) * restrict env variables start with HASURA_GRAPHQL_ for headers definition in actions & event triggers * update CHANGELOG.md * Apply suggestions from code review Co-authored-by: Vamshi Surabhi <0x777@users.noreply.github.com> * fix introspection query if any enum column present in primary key (fix #5200) (#5522) * Fix telemetry reporting of transport (websocket was reported as http) * add log kinds in cli-migrations image (#5529) * add log kinds in cli-migrations image * give hint to resolve timeout error * minor changes and CHANGELOG * server: set hasura.tracecontext in RQL mutations [#5542] (#5555) * server: set hasura.tracecontext in RQL mutations [#5542] * Update test suite Co-authored-by: Tirumarai Selvan <tiru@hasura.io> * 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.

Nested array support for Data Connectors Backend and MongoDB ## Description This change adds support for querying into nested arrays in Data Connector agents that support such a concept (currently MongoDB). ### DC API changes - New API type `ColumnType` which allows representing the type of a "column" as either a scalar type, an object reference or an array of `ColumnType`s. This recursive definition allows arbitrary nesting of arrays of types. - The `type` fields in the API types `ColumnInfo` and `ColumnInsertSchema` now take a `ColumnType` instead of a `ScalarType`. - To ensure backwards compatibility, a `ColumnType` representing a scalar serialises and deserialises to the same representation as `ScalarType`. - In queries, the `Field` type now has a new constructor `NestedArrayField`. This contains a nested `Field` along with optional `limit`, `offset`, `where` and `order_by` arguments. (These optional arguments are not yet used by either HGE or the MongoDB agent.) ### MongoDB Haskell agent changes - The `/schema` endpoint will now recognise arrays within the JSON validation schema and generate corresponding arrays in the DC schema. - The `/query` endpoint will now handle `NestedArrayField`s within queries (although it does not yet handle `limit`, `offset`, `where` and `order_by`). ### HGE server changes - The `Backend` type class adds a new type family `XNestedArrays b` to enable nested arrays on a per-backend basis (currently enabled only for the `DataConnector` backend. - Within `RawColumnInfo` the column type is now represented by a new type `RawColumnType b` which mirrors the shape of the DC API `ColumnType`, but uses `XNestedObjects b` and `XNestedArrays b` type families to allow turning nested object and array supports on or off for a particular backend. In the `DataConnector` backend `API.CustomType` is converted into `RawColumnInfo 'DataConnector` while building the schema. - In the next stage of schema building, the `RawColumnInfo` is converted into a `StructuredColumnInfo` which allows us to represent the three different types of columns: scalar, object and array. TODO: the `StructuredColumnInfo` looks very similar to the Logical Model types. The main difference is that it uses the `XNestedObjects` and `XNestedArrays` type families. We should be able to combine these two representations. - The `StructuredColumnInfo` is then placed into a `FIColumn` `FieldInfo`. This involved some refactoring of `FieldInfo` as I had previously split out `FINestedObject` into a separate constructor. However it works out better to represent all "column" fields (i.e. scalar, object and array) using `FIColumn` as this make it easier to implement permission checking correctly. This is the reason the `StructuredColumnInfo` was needed. - Next, the `FieldInfo` are used to generate `FieldParser`s. We add a new constructor to `AnnFieldG` for `AFNestedArray`. An `AFNestedArray` field parser can contain either a simple array selection or an array aggregate. Simple array `FieldParsers` are currently limited to subfield selection. We will add support for limit, offset, where and order_by in a future PR. We also don't yet generate array aggregate `FieldParsers. - The new `AFNestedArray` field is handled by the `QueryPlan` module in the `DataConnector` backend. There we generate an `API.NestedArrayField` from the AFNestedArray. We also handle nested arrays when reshaping the response from the DC agent. ## Limitations - Support for limit, offset, filter (where) and order_by is not yet fully implemented, although it should not be hard to add this - Support for aggregations on nested arrays is not yet fully implemented - Permissions involving nested arrays (and objects) not yet implemented - This should be integrated with Logical Model types, but that will happen in a separate PR PR-URL: https://github.com/hasura/graphql-engine-mono/pull/9149 GitOrigin-RevId: 0e7b71a994fc1d2ca1ef73bfe7b96e95b5328531

Nested array support for Data Connectors Backend and MongoDB ## Description This change adds support for querying into nested arrays in Data Connector agents that support such a concept (currently MongoDB). ### DC API changes - New API type `ColumnType` which allows representing the type of a "column" as either a scalar type, an object reference or an array of `ColumnType`s. This recursive definition allows arbitrary nesting of arrays of types. - The `type` fields in the API types `ColumnInfo` and `ColumnInsertSchema` now take a `ColumnType` instead of a `ScalarType`. - To ensure backwards compatibility, a `ColumnType` representing a scalar serialises and deserialises to the same representation as `ScalarType`. - In queries, the `Field` type now has a new constructor `NestedArrayField`. This contains a nested `Field` along with optional `limit`, `offset`, `where` and `order_by` arguments. (These optional arguments are not yet used by either HGE or the MongoDB agent.) ### MongoDB Haskell agent changes - The `/schema` endpoint will now recognise arrays within the JSON validation schema and generate corresponding arrays in the DC schema. - The `/query` endpoint will now handle `NestedArrayField`s within queries (although it does not yet handle `limit`, `offset`, `where` and `order_by`). ### HGE server changes - The `Backend` type class adds a new type family `XNestedArrays b` to enable nested arrays on a per-backend basis (currently enabled only for the `DataConnector` backend. - Within `RawColumnInfo` the column type is now represented by a new type `RawColumnType b` which mirrors the shape of the DC API `ColumnType`, but uses `XNestedObjects b` and `XNestedArrays b` type families to allow turning nested object and array supports on or off for a particular backend. In the `DataConnector` backend `API.CustomType` is converted into `RawColumnInfo 'DataConnector` while building the schema. - In the next stage of schema building, the `RawColumnInfo` is converted into a `StructuredColumnInfo` which allows us to represent the three different types of columns: scalar, object and array. TODO: the `StructuredColumnInfo` looks very similar to the Logical Model types. The main difference is that it uses the `XNestedObjects` and `XNestedArrays` type families. We should be able to combine these two representations. - The `StructuredColumnInfo` is then placed into a `FIColumn` `FieldInfo`. This involved some refactoring of `FieldInfo` as I had previously split out `FINestedObject` into a separate constructor. However it works out better to represent all "column" fields (i.e. scalar, object and array) using `FIColumn` as this make it easier to implement permission checking correctly. This is the reason the `StructuredColumnInfo` was needed. - Next, the `FieldInfo` are used to generate `FieldParser`s. We add a new constructor to `AnnFieldG` for `AFNestedArray`. An `AFNestedArray` field parser can contain either a simple array selection or an array aggregate. Simple array `FieldParsers` are currently limited to subfield selection. We will add support for limit, offset, where and order_by in a future PR. We also don't yet generate array aggregate `FieldParsers. - The new `AFNestedArray` field is handled by the `QueryPlan` module in the `DataConnector` backend. There we generate an `API.NestedArrayField` from the AFNestedArray. We also handle nested arrays when reshaping the response from the DC agent. ## Limitations - Support for limit, offset, filter (where) and order_by is not yet fully implemented, although it should not be hard to add this - Support for aggregations on nested arrays is not yet fully implemented - Permissions involving nested arrays (and objects) not yet implemented - This should be integrated with Logical Model types, but that will happen in a separate PR PR-URL: https://github.com/hasura/graphql-engine-mono/pull/9149 GitOrigin-RevId: 0e7b71a994fc1d2ca1ef73bfe7b96e95b5328531

[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 Co-authored-by: Vamshi Surabhi <6562944+0x777@users.noreply.github.com> GitOrigin-RevId: 3b8ee1e11f5ceca80fe294f8c074d42fbccfec63

Support nested object fields in DC API and use this to implement nest… ## Description This change adds support for nested object fields in HGE IR and Schema Cache, the Data Connectors backend and API, and the MongoDB agent. ### Data Connector API changes - The `/schema` endpoint response now includes an optional set of GraphQL type definitions. Table column types can refer to these definitions by name. - Queries can now include a new field type `object` which contains a column name and a nested query. This allows querying into a nested object within a field. ### MongoDB agent changes - Add support for querying into nested documents using the new `object` field type. ### HGE changes - The `Backend` type class has a new type family `XNestedObjects b` which controls whether or not a backend supports querying into nested objects. This is currently enabled only for the `DataConnector` backend. - For backends that support nested objects, the `FieldInfo` type gets a new constructor `FINestedObject`, and the `AnnFieldG` type gets a new constructor `AFNestedObject`. - If the DC `/schema` endpoint returns any custom GraphQL type definitions they are stored in the `TableInfo` for each table in the source. - During schema cache building, the function `addNonColumnFields` will check whether any column types match custom GraphQL object types stored in the `TableInfo`. If so, they are converted into `FINestedObject` instead of `FIColumn` in the `FieldInfoMap`. - When building the `FieldParser`s from `FieldInfo` (function `fieldSelection`) any `FINestedObject` fields are converted into nested object parsers returning `AFNestedObject`. - The `DataConnector` query planner converts `AFNestedObject` fields into `object` field types in the query sent to the agent. ## Limitations ### HGE not yet implemented: - Support for nested arrays - Support for nested objects/arrays in mutations - Support for nested objects/arrays in order-by - Support for filters (`where`) in nested objects/arrays - Support for adding custom GraphQL types via track table metadata API - Support for interface and union types - Tests for nested objects ### Mongo agent not yet implemented: - Generate nested object types from validation schema - Support for aggregates - Support for order-by - Configure agent port - Build agent in CI - Agent tests for nested objects and MongoDB agent PR-URL: https://github.com/hasura/graphql-engine-mono/pull/7844 GitOrigin-RevId: aec9ec1e4216293286a68f9b1af6f3f5317db423

Support nested object fields in DC API and use this to implement nest… ## Description This change adds support for nested object fields in HGE IR and Schema Cache, the Data Connectors backend and API, and the MongoDB agent. ### Data Connector API changes - The `/schema` endpoint response now includes an optional set of GraphQL type definitions. Table column types can refer to these definitions by name. - Queries can now include a new field type `object` which contains a column name and a nested query. This allows querying into a nested object within a field. ### MongoDB agent changes - Add support for querying into nested documents using the new `object` field type. ### HGE changes - The `Backend` type class has a new type family `XNestedObjects b` which controls whether or not a backend supports querying into nested objects. This is currently enabled only for the `DataConnector` backend. - For backends that support nested objects, the `FieldInfo` type gets a new constructor `FINestedObject`, and the `AnnFieldG` type gets a new constructor `AFNestedObject`. - If the DC `/schema` endpoint returns any custom GraphQL type definitions they are stored in the `TableInfo` for each table in the source. - During schema cache building, the function `addNonColumnFields` will check whether any column types match custom GraphQL object types stored in the `TableInfo`. If so, they are converted into `FINestedObject` instead of `FIColumn` in the `FieldInfoMap`. - When building the `FieldParser`s from `FieldInfo` (function `fieldSelection`) any `FINestedObject` fields are converted into nested object parsers returning `AFNestedObject`. - The `DataConnector` query planner converts `AFNestedObject` fields into `object` field types in the query sent to the agent. ## Limitations ### HGE not yet implemented: - Support for nested arrays - Support for nested objects/arrays in mutations - Support for nested objects/arrays in order-by - Support for filters (`where`) in nested objects/arrays - Support for adding custom GraphQL types via track table metadata API - Support for interface and union types - Tests for nested objects ### Mongo agent not yet implemented: - Generate nested object types from validation schema - Support for aggregates - Support for order-by - Configure agent port - Build agent in CI - Agent tests for nested objects and MongoDB agent PR-URL: https://github.com/hasura/graphql-engine-mono/pull/7844 GitOrigin-RevId: aec9ec1e4216293286a68f9b1af6f3f5317db423

Nested array support for Data Connectors Backend and MongoDB ## Description This change adds support for querying into nested arrays in Data Connector agents that support such a concept (currently MongoDB). ### DC API changes - New API type `ColumnType` which allows representing the type of a "column" as either a scalar type, an object reference or an array of `ColumnType`s. This recursive definition allows arbitrary nesting of arrays of types. - The `type` fields in the API types `ColumnInfo` and `ColumnInsertSchema` now take a `ColumnType` instead of a `ScalarType`. - To ensure backwards compatibility, a `ColumnType` representing a scalar serialises and deserialises to the same representation as `ScalarType`. - In queries, the `Field` type now has a new constructor `NestedArrayField`. This contains a nested `Field` along with optional `limit`, `offset`, `where` and `order_by` arguments. (These optional arguments are not yet used by either HGE or the MongoDB agent.) ### MongoDB Haskell agent changes - The `/schema` endpoint will now recognise arrays within the JSON validation schema and generate corresponding arrays in the DC schema. - The `/query` endpoint will now handle `NestedArrayField`s within queries (although it does not yet handle `limit`, `offset`, `where` and `order_by`). ### HGE server changes - The `Backend` type class adds a new type family `XNestedArrays b` to enable nested arrays on a per-backend basis (currently enabled only for the `DataConnector` backend. - Within `RawColumnInfo` the column type is now represented by a new type `RawColumnType b` which mirrors the shape of the DC API `ColumnType`, but uses `XNestedObjects b` and `XNestedArrays b` type families to allow turning nested object and array supports on or off for a particular backend. In the `DataConnector` backend `API.CustomType` is converted into `RawColumnInfo 'DataConnector` while building the schema. - In the next stage of schema building, the `RawColumnInfo` is converted into a `StructuredColumnInfo` which allows us to represent the three different types of columns: scalar, object and array. TODO: the `StructuredColumnInfo` looks very similar to the Logical Model types. The main difference is that it uses the `XNestedObjects` and `XNestedArrays` type families. We should be able to combine these two representations. - The `StructuredColumnInfo` is then placed into a `FIColumn` `FieldInfo`. This involved some refactoring of `FieldInfo` as I had previously split out `FINestedObject` into a separate constructor. However it works out better to represent all "column" fields (i.e. scalar, object and array) using `FIColumn` as this make it easier to implement permission checking correctly. This is the reason the `StructuredColumnInfo` was needed. - Next, the `FieldInfo` are used to generate `FieldParser`s. We add a new constructor to `AnnFieldG` for `AFNestedArray`. An `AFNestedArray` field parser can contain either a simple array selection or an array aggregate. Simple array `FieldParsers` are currently limited to subfield selection. We will add support for limit, offset, where and order_by in a future PR. We also don't yet generate array aggregate `FieldParsers. - The new `AFNestedArray` field is handled by the `QueryPlan` module in the `DataConnector` backend. There we generate an `API.NestedArrayField` from the AFNestedArray. We also handle nested arrays when reshaping the response from the DC agent. ## Limitations - Support for limit, offset, filter (where) and order_by is not yet fully implemented, although it should not be hard to add this - Support for aggregations on nested arrays is not yet fully implemented - Permissions involving nested arrays (and objects) not yet implemented - This should be integrated with Logical Model types, but that will happen in a separate PR PR-URL: https://github.com/hasura/graphql-engine-mono/pull/9149 GitOrigin-RevId: 0e7b71a994fc1d2ca1ef73bfe7b96e95b5328531

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 2b0e3774 * [skip ci] remove cherry-picked commit from commit_diff.txt * server: include additional fields in scheduled trigger webhook payload (#5262) * include scheduled triggers metadata in the webhook body Co-authored-by: Tirumarai Selvan <tiru@hasura.io> * server: call the webhook asynchronously in event triggers (#5352) * server: call the webhook asynchronosly in event triggers * Expose all modules in Cabal file (#5371) * [skip ci] update commit_diff.txt * [skip ci] fix cast exp parser & few TODOs * [skip ci] fix remote fields arguments * [skip ci] fix few more TODO, no-op refactor, move resolve/action.hs to execute/action.hs * Pass environment variables around as a data structure, via @sordina (#5374) * Pass environment variables around as a data structure, via @sordina * Resolving build error * Adding Environment passing note to changelog * Removing references to ILTPollerLog as this seems to have been reintroduced from a bad merge * removing commented-out imports * Language pragmas already set by project * Linking async thread * Apply suggestions from code review Use `runQueryTx` instead of `runLazyTx` for queries. * remove the non-user facing entry in the changelog Co-authored-by: Phil Freeman <paf31@cantab.net> Co-authored-by: Phil Freeman <phil@hasura.io> Co-authored-by: Vamshi Surabhi <0x777@users.noreply.github.com> * [skip ci] fix: restrict remote relationship field generation for hasura queries * [skip ci] no-op refactor; move insert execution code from schema parser module * server: call the webhook asynchronously in event triggers (#5352) * server: call the webhook asynchronosly in event triggers * Expose all modules in Cabal file (#5371) * [skip ci] update commit_diff.txt * Pass environment variables around as a data structure, via @sordina (#5374) * Pass environment variables around as a data structure, via @sordina * Resolving build error * Adding Environment passing note to changelog * Removing references to ILTPollerLog as this seems to have been reintroduced from a bad merge * removing commented-out imports * Language pragmas already set by project * Linking async thread * Apply suggestions from code review Use `runQueryTx` instead of `runLazyTx` for queries. * remove the non-user facing entry in the changelog Co-authored-by: Phil Freeman <paf31@cantab.net> Co-authored-by: Phil Freeman <phil@hasura.io> Co-authored-by: Vamshi Surabhi <0x777@users.noreply.github.com> * [skip ci] implement header checking Probably closes #14 and #3659. * server: refactor 'pollQuery' to have a hook to process 'PollDetails' (#5391) Co-authored-by: Vamshi Surabhi <0x777@users.noreply.github.com> * 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] fix integer and float parsing error code * [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] no-op refactor and removed couple of FIXMEs * [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] fix fragment error path * [skip ci] fix node error code * [skip ci] fix paths in insert queries * [skip ci] fix path in objects * [skip ci] manually alter node id path for consistency * [skip ci] more node error fixups * [skip ci] one last relay error message fix * [skip ci] update commit_diff * Propagate the trace context to event triggers (#5409) * Propagate the trace context to event triggers * Handle missing trace and span IDs * Store trace context as one LOCAL * Add migrations * Documentation * changelog * Fix warnings * Respond to code review suggestions * Respond to code review * Undo changelog * Update CHANGELOG.md Co-authored-by: Vamshi Surabhi <0x777@users.noreply.github.com> * server: log request/response sizes for event triggers (#5463) * server: log request/response sizes for event triggers event triggers (and scheduled triggers) now have request/response size in their logs. * add changelog entry * Tracing: Simplify HTTP traced request (#5451) Remove the Inversion of Control (SuspendRequest) and simplify the tracing of HTTP Requests. Co-authored-by: Phil Freeman <phil@hasura.io> * Attach request ID as tracing metadata (#5456) * Propagate the trace context to event triggers * Handle missing trace and span IDs * Store trace context as one LOCAL * Add migrations * Documentation * Include the request ID as trace metadata * changelog * Fix warnings * Respond to code review suggestions * Respond to code review * Undo changelog * Update CHANGELOG.md * Typo Co-authored-by: Vamshi Surabhi <0x777@users.noreply.github.com> * server: add logging for action handlers (#5471) * server: add logging for action handlers * add changelog entry * change action-handler log type from internal to non-internal * fix action-handler-log name * server: pass http and websocket request to logging context (#5470) * 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) * fix review comments Co-authored-by: Phil Freeman <phil@hasura.io> * server: stop eventing subsystem threads when shutting down (#5479) * server: stop eventing subsystem threads when shutting down * Apply suggestions from code review Co-authored-by: Karthikeyan Chinnakonda <chkarthikeyan95@gmail.com> Co-authored-by: Phil Freeman <phil@hasura.io> Co-authored-by: Phil Freeman <paf31@cantab.net> Co-authored-by: Karthikeyan Chinnakonda <chkarthikeyan95@gmail.com> * [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 * [skip ci] fix error message for type mismatch * [skip ci] fix variable path in test * [skip ci] adjust tests after bug fix * [skip ci] more tests fixing * Add hdb_catalog.current_setting abstraction for reading Hasura settings 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 * [skip ci] Avoid converting to/from Map * [skip ci] Apply some hlint suggestions * [skip ci] remove redundant constraints from buildLiveQueryPlan and explainGQLQuery * [skip ci] add NOTEs about missing Tracing constraints in PDV from master * Remove -fdefer-typed-holes, fix warnings * Update cabal.project.freeze * Limit GHC’s heap size to 8GB in CI to avoid the OOM killer * Commit package-lock.json for Python tests’ remote schema server * restrict env variables start with HASURA_GRAPHQL_ for headers configuration in actions, event triggers & remote schemas (#5519) * restrict env variables start with HASURA_GRAPHQL_ for headers definition in actions & event triggers * update CHANGELOG.md * Apply suggestions from code review Co-authored-by: Vamshi Surabhi <0x777@users.noreply.github.com> * add test for table_by_pk node when roles doesn't have permission to PK * [skip ci] fix introspection query if any enum column present in primary key (fix #5200) (#5522) * [skip ci] test case fix for a6450e126bc2d98bcfd3791501986e4627ce6c6f * [skip ci] add tests to agg queries when role doesn't have access to any cols * 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 * [skip ci] add positive counterparts to some of the negative permission tests * fix args missing their description in introspect * [skip ci] Remove unused function; insert missing markNotReusable call * [skip ci] Add a Note about InputValue * [skip ci] Delete LegacySchema/ 🎉 * [skip ci] Delete GraphQL/{Resolve,Validate}/ 🎉 * [skip ci] Delete top-level Resolve/Validate modules; tidy .cabal file * [skip ci] Delete LegacySchema top-level module Somehow I missed this one. * fix input value to json * [skip ci] elaborate on JSON objects in GraphQL * [skip ci] add missing file * [skip ci] add a test with subscription containing remote joins * add a test with remote joins in mutation output * [skip ci] Add some comments to Schema/Mutation.hs * [skip ci] Remove no longer needed code from RemoteServer.hs * [skip ci] Use a helper function to generate conflict clause parsers * [skip ci] fix type checker error in fields with default value * capitalize the header keys in select_articles_without_required_headers * Somehow, this was the reason the tests were failing. I have no idea, why! * [skip ci] Add a long Note about optional fields and nullability * Improve comments a bit; simplify Schema/Common.hs a bit * [skip ci] full implementation of 5.8.5 type checking. * [skip ci] fix validation test teardown * [skip ci] fix schema stitching test * fix remote schema ignoring enum nullability * [skip ci] fix fieldOptional to not discard nullability * revert nullability of use_spheroid * fix comment * add required remote fields with arguments for tests * [skip ci] add missing docstrings * [skip ci] fixed description of remote fields * [skip ci] change docstring for consistency * fix several schema inconsistencies * revert behaviour change in function arguments parsing * fix remaining nullability issues in new schema * minor no-op refactor; use isListType from graphql-parser-hs * 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) * Show method and complete URI in traced HTTP calls (#5525) Co-authored-by: Vamshi Surabhi <0x777@users.noreply.github.com> * restrict env variables start with HASURA_GRAPHQL_ for headers configuration in actions, event triggers & remote schemas (#5519) * restrict env variables start with HASURA_GRAPHQL_ for headers definition in actions & event triggers * update CHANGELOG.md * Apply suggestions from code review Co-authored-by: Vamshi Surabhi <0x777@users.noreply.github.com> * fix introspection query if any enum column present in primary key (fix #5200) (#5522) * Fix telemetry reporting of transport (websocket was reported as http) * add log kinds in cli-migrations image (#5529) * add log kinds in cli-migrations image * give hint to resolve timeout error * minor changes and CHANGELOG * server: set hasura.tracecontext in RQL mutations [#5542] (#5555) * server: set hasura.tracecontext in RQL mutations [#5542] * Update test suite Co-authored-by: Tirumarai Selvan <tiru@hasura.io> * 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 0f9a5afa59a88f6824f4d63d58db246a5ba3fb03. This undoes a cherry-pick of 34288e1eb5f2c5dad9e6d1e05453dd52397dc970 that was already done previously in a6450e126bc2d98bcfd3791501986e4627ce6c6f, and subsequently fixed for PDV in 70e89dc250f8ddc6e2b7930bbe2b3eeaa6dbe1db * 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 bd6bb40355b3d189a46c0312eb52225e18be57b3. 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 66e85ab9fbd56cca2c28a80201f6604fbe811b85. * Remove circular reference in cabal.project.freeze Co-authored-by: Karthikeyan Chinnakonda <karthikeyan@hasura.io> Co-authored-by: Auke Booij <auke@hasura.io> Co-authored-by: Tirumarai Selvan <tiru@hasura.io> Co-authored-by: Marion Schleifer <marion@hasura.io> Co-authored-by: Aleksandra Sikora <ola.zxcvbnm@gmail.com> Co-authored-by: Brandon Simmons <brandon.m.simmons@gmail.com> Co-authored-by: Vamshi Surabhi <0x777@users.noreply.github.com> Co-authored-by: Anon Ray <rayanon004@gmail.com> Co-authored-by: rakeshkky <12475069+rakeshkky@users.noreply.github.com> Co-authored-by: Anon Ray <ecthiender@users.noreply.github.com> Co-authored-by: Vamshi Surabhi <vamshi@hasura.io> Co-authored-by: Antoine Leblanc <antoine@hasura.io> Co-authored-by: Brandon Simmons <brandon@hasura.io> Co-authored-by: Phil Freeman <phil@hasura.io> Co-authored-by: Lyndon Maydwell <lyndon@sordina.net> Co-authored-by: Phil Freeman <paf31@cantab.net> Co-authored-by: Naveen Naidu <naveennaidu479@gmail.com> Co-authored-by: Karthikeyan Chinnakonda <chkarthikeyan95@gmail.com> Co-authored-by: Nizar Malangadan <nizar-m@users.noreply.github.com> Co-authored-by: Antoine Leblanc <crucuny@gmail.com> Co-authored-by: Auke Booij <auke@tulcod.com>

Role-invariant schema constructors We build the GraphQL schema by combining building blocks such as `tableSelectionSet` and `columnParser`. These building blocks individually build `{InputFields,Field,}Parser` objects. Those object specify the valid GraphQL schema. Since the GraphQL schema is role-dependent, at some point we need to know what fragment of the GraphQL schema a specific role is allowed to access, and this is stored in `{Sel,Upd,Ins,Del}PermInfo` objects. We have passed around these permission objects as function arguments to the schema building blocks since we first started dealing with permissions during the PDV refactor - see hasura/graphql-engine@5168b99e463199b1934d8645bd6cd37eddb64ae1 in hasura/graphql-engine#4111. This means that, for instance, `tableSelectionSet` has as its type: ```haskell tableSelectionSet :: forall b r m n. MonadBuildSchema b r m n => SourceName -> TableInfo b -> SelPermInfo b -> m (Parser 'Output n (AnnotatedFields b)) ``` There are three reasons to change this. 1. We often pass a `Maybe (xPermInfo b)` instead of a proper `xPermInfo b`, and it's not clear what the intended semantics of this is. Some potential improvements on the data types involved are discussed in issue hasura/graphql-engine-mono#3125. 2. In most cases we also already pass a `TableInfo b`, and together with the `MonadRole` that is usually also in scope, this means that we could look up the required permissions regardless: so passing the permissions explicitly undermines the "single source of truth" principle. Breaking this principle also makes the code more difficult to read. 3. We are working towards role-based parsers (see hasura/graphql-engine-mono#2711), where the `{InputFields,Field,}Parser` objects are constructed in a role-invariant way, so that we have a single object that can be used for all roles. In particular, this means that the schema building blocks _need_ to be constructed in a role-invariant way. While this PR doesn't accomplish that, it does reduce the amount of role-specific arguments being passed, thus fixing hasura/graphql-engine-mono#3068. Concretely, this PR simply drops the `xPermInfo b` argument from almost all schema building blocks. Instead these objects are looked up from the `TableInfo b` as-needed. The resulting code is considerably simpler and shorter. One way to interpret this change is as follows. Before this PR, we figured out permissions at the top-level in `Hasura.GraphQL.Schema`, passing down the obtained `xPermInfo` objects as required. After this PR, we have a bottom-up approach where the schema building blocks themselves decide whether they want to be included for a particular role. So this moves some permission logic out of `Hasura.GraphQL.Schema`, which is very complex.

server: delete the `Cacheable` type class in favor of `Eq` What is the `Cacheable` type class about? ```haskell class Eq a => Cacheable a where unchanged :: Accesses -> a -> a -> Bool default unchanged :: (Generic a, GCacheable (Rep a)) => Accesses -> a -> a -> Bool unchanged accesses a b = gunchanged (from a) (from b) accesses ``` Its only method is an alternative to `(==)`. The added value of `unchanged` (and the additional `Accesses` argument) arises _only_ for one type, namely `Dependency`. Indeed, the `Cacheable (Dependency a)` instance is non-trivial, whereas every other `Cacheable` instance is completely boilerplate (and indeed either generated from `Generic`, or simply `unchanged _ = (==)`). The `Cacheable (Dependency a)` instance is the only one where the `Accesses` argument is not just passed onwards. The only callsite of the `unchanged` method is in the `ArrowCache (Rule m)` method. That is to say that the `Cacheable` type class is used to decide when we can re-use parts of the schema cache between Metadata operations. So what is the `Cacheable (Dependency a)` instance about? Normally, the output of a `Rule m a b` is re-used when the new input (of type `a`) is equal to the old one. But sometimes, that's too coarse: it might be that a certain `Rule m a b` only depends on a small part of its input of type `a`. A `Dependency` allows us to spell out what parts of `a` are being depended on, and these parts are recorded as values of types `Access a` in the state `Accesses`. If the input `a` changes, but not in a way that touches the recorded `Accesses`, then the output `b` of that rule can be re-used without recomputing. So now you understand _why_ we're passing `Accesses` to the `unchanged` method: `unchanged` is an equality check in disguise that just needs some additional context. But we don't need to pass `Accesses` as a function argument. We can use the `reflection` package to pass it as type-level context. So the core of this PR is that we change the instance declaration from ```haskell instance (Cacheable a) => Cacheable (Dependency a) where ``` to ```haskell instance (Given Accesses, Eq a) => Eq (Dependency a) where ``` and use `(==)` instead of `unchanged`. If you haven't seen `reflection` before: it's like a `MonadReader`, but it doesn't require a `Monad`. In order to pass the current `Accesses` value, instead of simply passing the `Accesses` as a function argument, we need to instantiate the `Given Accesses` context. We use the `give` method from the `reflection` package for that. ```haskell give :: forall r. Accesses -> (Given Accesses => r) -> r unchanged :: (Given Accesses => Eq a) => Accesses -> a -> a -> Bool unchanged accesses a b = give accesses (a == b) ``` With these three components in place, we can delete the `Cacheable` type class entirely. The remainder of this PR is just to remove the `Cacheable` type class and its instances.

Support nested object fields in DC API and use this to implement nest… ## Description This change adds support for nested object fields in HGE IR and Schema Cache, the Data Connectors backend and API, and the MongoDB agent. ### Data Connector API changes - The `/schema` endpoint response now includes an optional set of GraphQL type definitions. Table column types can refer to these definitions by name. - Queries can now include a new field type `object` which contains a column name and a nested query. This allows querying into a nested object within a field. ### MongoDB agent changes - Add support for querying into nested documents using the new `object` field type. ### HGE changes - The `Backend` type class has a new type family `XNestedObjects b` which controls whether or not a backend supports querying into nested objects. This is currently enabled only for the `DataConnector` backend. - For backends that support nested objects, the `FieldInfo` type gets a new constructor `FINestedObject`, and the `AnnFieldG` type gets a new constructor `AFNestedObject`. - If the DC `/schema` endpoint returns any custom GraphQL type definitions they are stored in the `TableInfo` for each table in the source. - During schema cache building, the function `addNonColumnFields` will check whether any column types match custom GraphQL object types stored in the `TableInfo`. If so, they are converted into `FINestedObject` instead of `FIColumn` in the `FieldInfoMap`. - When building the `FieldParser`s from `FieldInfo` (function `fieldSelection`) any `FINestedObject` fields are converted into nested object parsers returning `AFNestedObject`. - The `DataConnector` query planner converts `AFNestedObject` fields into `object` field types in the query sent to the agent. ## Limitations ### HGE not yet implemented: - Support for nested arrays - Support for nested objects/arrays in mutations - Support for nested objects/arrays in order-by - Support for filters (`where`) in nested objects/arrays - Support for adding custom GraphQL types via track table metadata API - Support for interface and union types - Tests for nested objects ### Mongo agent not yet implemented: - Generate nested object types from validation schema - Support for aggregates - Support for order-by - Configure agent port - Build agent in CI - Agent tests for nested objects and MongoDB agent PR-URL: https://github.com/hasura/graphql-engine-mono/pull/7844 GitOrigin-RevId: aec9ec1e4216293286a68f9b1af6f3f5317db423

Nested array support for Data Connectors Backend and MongoDB ## Description This change adds support for querying into nested arrays in Data Connector agents that support such a concept (currently MongoDB). ### DC API changes - New API type `ColumnType` which allows representing the type of a "column" as either a scalar type, an object reference or an array of `ColumnType`s. This recursive definition allows arbitrary nesting of arrays of types. - The `type` fields in the API types `ColumnInfo` and `ColumnInsertSchema` now take a `ColumnType` instead of a `ScalarType`. - To ensure backwards compatibility, a `ColumnType` representing a scalar serialises and deserialises to the same representation as `ScalarType`. - In queries, the `Field` type now has a new constructor `NestedArrayField`. This contains a nested `Field` along with optional `limit`, `offset`, `where` and `order_by` arguments. (These optional arguments are not yet used by either HGE or the MongoDB agent.) ### MongoDB Haskell agent changes - The `/schema` endpoint will now recognise arrays within the JSON validation schema and generate corresponding arrays in the DC schema. - The `/query` endpoint will now handle `NestedArrayField`s within queries (although it does not yet handle `limit`, `offset`, `where` and `order_by`). ### HGE server changes - The `Backend` type class adds a new type family `XNestedArrays b` to enable nested arrays on a per-backend basis (currently enabled only for the `DataConnector` backend. - Within `RawColumnInfo` the column type is now represented by a new type `RawColumnType b` which mirrors the shape of the DC API `ColumnType`, but uses `XNestedObjects b` and `XNestedArrays b` type families to allow turning nested object and array supports on or off for a particular backend. In the `DataConnector` backend `API.CustomType` is converted into `RawColumnInfo 'DataConnector` while building the schema. - In the next stage of schema building, the `RawColumnInfo` is converted into a `StructuredColumnInfo` which allows us to represent the three different types of columns: scalar, object and array. TODO: the `StructuredColumnInfo` looks very similar to the Logical Model types. The main difference is that it uses the `XNestedObjects` and `XNestedArrays` type families. We should be able to combine these two representations. - The `StructuredColumnInfo` is then placed into a `FIColumn` `FieldInfo`. This involved some refactoring of `FieldInfo` as I had previously split out `FINestedObject` into a separate constructor. However it works out better to represent all "column" fields (i.e. scalar, object and array) using `FIColumn` as this make it easier to implement permission checking correctly. This is the reason the `StructuredColumnInfo` was needed. - Next, the `FieldInfo` are used to generate `FieldParser`s. We add a new constructor to `AnnFieldG` for `AFNestedArray`. An `AFNestedArray` field parser can contain either a simple array selection or an array aggregate. Simple array `FieldParsers` are currently limited to subfield selection. We will add support for limit, offset, where and order_by in a future PR. We also don't yet generate array aggregate `FieldParsers. - The new `AFNestedArray` field is handled by the `QueryPlan` module in the `DataConnector` backend. There we generate an `API.NestedArrayField` from the AFNestedArray. We also handle nested arrays when reshaping the response from the DC agent. ## Limitations - Support for limit, offset, filter (where) and order_by is not yet fully implemented, although it should not be hard to add this - Support for aggregations on nested arrays is not yet fully implemented - Permissions involving nested arrays (and objects) not yet implemented - This should be integrated with Logical Model types, but that will happen in a separate PR PR-URL: https://github.com/hasura/graphql-engine-mono/pull/9149 GitOrigin-RevId: 0e7b71a994fc1d2ca1ef73bfe7b96e95b5328531

This is the reason the `StructuredColumnInfo` was needed. - Next, the `FieldInfo` are used to generate `FieldParser`s. We add a new constructor to `AnnFieldG` for `AFNestedArray`. An `AFNestedArray` field parser can contain either a simple array selection or an array aggregate. Simple array `FieldParsers` are currently limited to subfield selection. We will add support for limit, offset, where and order_by in a future PR. We also don't yet generate array aggregate `FieldParsers. - The new `AFNestedArray` field is handled by the `QueryPlan` module in the `DataConnector` backend. There we generate an `API.NestedArrayField` from the AFNestedArray. We also handle nested arrays when reshaping the response from the DC agent. ## Limitations - Support for limit, offset, filter (where) and order_by is not yet fully implemented, although it should not be hard to add this - Support for aggregations on nested arrays is not yet fully implemented - Permissions involving nested arrays (and objects) not yet implemented - This should be integrated with Logical Model types, but that will happen in a separate PR PR-URL: https://github.com/hasura/graphql-engine-mono/pull/9149 GitOrigin-RevId: 0e7b71a994fc1d2ca1ef73bfe7b96e95b5328531

Role-invariant schema constructors We build the GraphQL schema by combining building blocks such as `tableSelectionSet` and `columnParser`. These building blocks individually build `{InputFields,Field,}Parser` objects. Those object specify the valid GraphQL schema. Since the GraphQL schema is role-dependent, at some point we need to know what fragment of the GraphQL schema a specific role is allowed to access, and this is stored in `{Sel,Upd,Ins,Del}PermInfo` objects. We have passed around these permission objects as function arguments to the schema building blocks since we first started dealing with permissions during the PDV refactor - see hasura/graphql-engine@5168b99e463199b1934d8645bd6cd37eddb64ae1 in hasura/graphql-engine#4111. This means that, for instance, `tableSelectionSet` has as its type: ```haskell tableSelectionSet :: forall b r m n. MonadBuildSchema b r m n => SourceName -> TableInfo b -> SelPermInfo b -> m (Parser 'Output n (AnnotatedFields b)) ``` There are three reasons to change this. 1. We often pass a `Maybe (xPermInfo b)` instead of a proper `xPermInfo b`, and it's not clear what the intended semantics of this is. Some potential improvements on the data types involved are discussed in issue hasura/graphql-engine-mono#3125. 2. In most cases we also already pass a `TableInfo b`, and together with the `MonadRole` that is usually also in scope, this means that we could look up the required permissions regardless: so passing the permissions explicitly undermines the "single source of truth" principle. Breaking this principle also makes the code more difficult to read. 3. We are working towards role-based parsers (see hasura/graphql-engine-mono#2711), where the `{InputFields,Field,}Parser` objects are constructed in a role-invariant way, so that we have a single object that can be used for all roles. In particular, this means that the schema building blocks _need_ to be constructed in a role-invariant way. While this PR doesn't accomplish that, it does reduce the amount of role-specific arguments being passed, thus fixing hasura/graphql-engine-mono#3068. Concretely, this PR simply drops the `xPermInfo b` argument from almost all schema building blocks. Instead these objects are looked up from the `TableInfo b` as-needed. The resulting code is considerably simpler and shorter. One way to interpret this change is as follows. Before this PR, we figured out permissions at the top-level in `Hasura.GraphQL.Schema`, passing down the obtained `xPermInfo` objects as required. After this PR, we have a bottom-up approach where the schema building blocks themselves decide whether they want to be included for a particular role. So this moves some permission logic out of `Hasura.GraphQL.Schema`, which is very complex.

Nested array support for Data Connectors Backend and MongoDB ## Description This change adds support for querying into nested arrays in Data Connector agents that support such a concept (currently MongoDB). ### DC API changes - New API type `ColumnType` which allows representing the type of a "column" as either a scalar type, an object reference or an array of `ColumnType`s. This recursive definition allows arbitrary nesting of arrays of types. - The `type` fields in the API types `ColumnInfo` and `ColumnInsertSchema` now take a `ColumnType` instead of a `ScalarType`. - To ensure backwards compatibility, a `ColumnType` representing a scalar serialises and deserialises to the same representation as `ScalarType`. - In queries, the `Field` type now has a new constructor `NestedArrayField`. This contains a nested `Field` along with optional `limit`, `offset`, `where` and `order_by` arguments. (These optional arguments are not yet used by either HGE or the MongoDB agent.) ### MongoDB Haskell agent changes - The `/schema` endpoint will now recognise arrays within the JSON validation schema and generate corresponding arrays in the DC schema. - The `/query` endpoint will now handle `NestedArrayField`s within queries (although it does not yet handle `limit`, `offset`, `where` and `order_by`). ### HGE server changes - The `Backend` type class adds a new type family `XNestedArrays b` to enable nested arrays on a per-backend basis (currently enabled only for the `DataConnector` backend. - Within `RawColumnInfo` the column type is now represented by a new type `RawColumnType b` which mirrors the shape of the DC API `ColumnType`, but uses `XNestedObjects b` and `XNestedArrays b` type families to allow turning nested object and array supports on or off for a particular backend. In the `DataConnector` backend `API.CustomType` is converted into `RawColumnInfo 'DataConnector` while building the schema. - In the next stage of schema building, the `RawColumnInfo` is converted into a `StructuredColumnInfo` which allows us to represent the three different types of columns: scalar, object and array. TODO: the `StructuredColumnInfo` looks very similar to the Logical Model types. The main difference is that it uses the `XNestedObjects` and `XNestedArrays` type families. We should be able to combine these two representations. - The `StructuredColumnInfo` is then placed into a `FIColumn` `FieldInfo`. This involved some refactoring of `FieldInfo` as I had previously split out `FINestedObject` into a separate constructor. However it works out better to represent all "column" fields (i.e. scalar, object and array) using `FIColumn` as this make it easier to implement permission checking correctly. This is the reason the `StructuredColumnInfo` was needed. - Next, the `FieldInfo` are used to generate `FieldParser`s. We add a new constructor to `AnnFieldG` for `AFNestedArray`. An `AFNestedArray` field parser can contain either a simple array selection or an array aggregate. Simple array `FieldParsers` are currently limited to subfield selection. We will add support for limit, offset, where and order_by in a future PR. We also don't yet generate array aggregate `FieldParsers. - The new `AFNestedArray` field is handled by the `QueryPlan` module in the `DataConnector` backend. There we generate an `API.NestedArrayField` from the AFNestedArray. We also handle nested arrays when reshaping the response from the DC agent. ## Limitations - Support for limit, offset, filter (where) and order_by is not yet fully implemented, although it should not be hard to add this - Support for aggregations on nested arrays is not yet fully implemented - Permissions involving nested arrays (and objects) not yet implemented - This should be integrated with Logical Model types, but that will happen in a separate PR PR-URL: https://github.com/hasura/graphql-engine-mono/pull/9149 GitOrigin-RevId: 0e7b71a994fc1d2ca1ef73bfe7b96e95b5328531
