[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 |

server: progress on generic metadata
This PR generalizes a bunch of metadata structures. Most importantly, it changes `SourceCache` to hold existentially quantified values: ``` data BackendSourceInfo = forall b. Backend b => BackendSourceInfo (SourceInfo b) type SourceCache = HashMap SourceName BackendSourceInfo ``` This changes a *lot* of things throughout the code. For now, all code using the schema cache explicitly casts sources to Postgres, meaning that if any non-Postgres `SourceInfo` makes it to the cache, it'll be ignored. That means that after this PR is submitted, we can split work between two different aspects: - creating `SourceInfo` for other backends - handling those other sources down the line GitOrigin-RevId: fb9ea00f32e840fc33c5467896fb1dfa5283ab42 |

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 |
