Auke Booij fe8eabff19 server: fix the nullability of object relationships (fix hasura/graphql-engine#7201 )

When adding object relationships, we set the nullability of the generated GraphQL field based on whether the database backend enforces that the referenced data always exists. For manual relationships (corresponding to `manual_configuration`), the database backend is unaware of any relationship between data, and hence such fields are always set to be nullable.

For relationships generated from foreign key constraints (corresponding to `foreign_key_constraint_on`), we distinguish between two cases:

1. The "forward" object relationship from a referencing table (i.e. which has the foreign key constraint) to a referenced table. This should be set to be non-nullable when all referencing columns are non-nullable. But in fact, it used to set it to be non-nullable if *any* referencing column is non-nullable, which is only correct in Postgres when `MATCH FULL` is set (a flag we don't consider). This fixes that by changing a boolean conjunction to a disjunction.
2. The "reverse" object relationship from a referenced table to a referencing table which has the foreign key constraint. This should always be set to be nullable. But in fact, it used to always be set to non-nullable, as was reported in hasura/graphql-engine#7201. This fixes that.

Moreover, we have moved the computation of the nullability from `Hasura.RQL.DDL.Relationship` to `Hasura.GraphQL.Schema.Select`: this nullability used to be passed through the `riIsNullable` field of `RelInfo`, but for array relationships this information is not actually used, and moreover the remaining fields of `RelInfo` are already enough to deduce the nullability.

This also adds regression tests for both (1) and (2) above.

v2.0.0-alpha.9

We now support comparing columns across related tables. For example:

Consider two tables, items(id, name, quantity) and shopping_cart(id, item_id, quantity) and these two tables are related via the item_id column. Now, while defining insert permission on the shopping_cart table, there can be a check to insert an item into the shopping cart only when there are enough present in the items inventory.

v2.0.0-alpha.8

Support for 3D PostGIS Operators

We now support the use of the functions ST_3DDWithin and ST_3DIntersects in boolean expressions. Note that ST_3DIntersects requires PostGIS be built with SFCGAL support which may depend on the PostGIS distribution used.

Support for null values in boolean expressions

In v2, we introduced a breaking change, that aimed at fixing a long-standing issue: a null value in a boolean expression would always evaluate to True for all rows. For example, the following queries were all equivalent:

delete_users(where: {_id: {_eq: null}})  # field is null, which is as if it were omitted
delete_users(where: {_id: {}})           # object is empty, evaluates to True for all rows
delete_users(where: {})                  # object is empty, evaluates to True for all rows
delete_users()                           # delete all users

This behaviour was unintuitive, and could be an unpleasant surprise for users that expected the first query to mean "delete all users for whom the id column is null". Therefore in v2, we changed the implementation of boolean operators to reject null values, as we deemed it safer:

delete_users(where: {_id: {_eq: null}})  # error: argument of _eq cannot be null

However, this change broke the workflows of some of our users who were relying on this property of boolean operators. This was used, for instance, to conditionally enable a test:

query($isVerified: Boolean) {
  users(where: {_isVerified: {_eq: $isVerified}}) {
    name
  }
}

In the future, we will probably offer a way to explicitly choose which behaviour to use for each where clause; perhaps by introducing new and distinct operators that make it explicit that they will default to true if the value is null. In the meantime, this release provides a way to revert the engine to its previous behaviour: if the HASURA_GRAPHQL_V1_BOOLEAN_NULL_COLLAPSE environment variable is set to "true", null values in boolean expression will behave like they did in v1 for the following operators: _is_null, _eq, _neq, _in, _nin, _gt, _lt, _gte, _lte.

cli: fix errors being ignored during metadata apply in config v3 (fix #6784)

v2.0.0-alpha.7

Transactions for Postgres mutations

With v2 came the introduction of heterogeneous execution: in one query or mutation, you can target different sources: it is possible, for instance, in one mutation, to both insert a row in a table in a table on Postgres and another row in another table on MSSQL:

mutation {
  // goes to Postgres
  insert_author_one(object: {name: "Simon Peyton Jones"}) {
    name
  }

  // goes to MSSQL
  insert_publication_one(object: {name: "Template meta-programming for Haskell"}) {
    name
  }
}

However, heterogeneous execution has a cost: we can no longer run mutations as a transaction, given that each part may target a different database. This is a regression compared to v1.

While we want to fix this by offering, in the future, an explicit API that allows our users to choose when a series of mutations are executed as a transaction, for now we are introducing the following optimisation: when all the fields in a mutation target the same Postgres source, we will run them as a transaction like we would have in v1.

      }
    ) {
    point
  }
}

v1.4.0-alpha.1

REST Endpoints

The RESTified GraphQL Endpoints API allows for the use of a REST interface to saved GraphQL queries and mutations.

Users specify the query or mutation they wish to make available, as well a URL template. Segments of the URL template can potentially capture data to be used as GraphQL variables.

See the documentation at graphql/core/api-reference/restified for more information.

Heterogeneous execution

Previous releases have allowed queries to request data from either Postgres or remote schemas, but not both. This release removes that restriction, so multiple data sources may be mixed within a single query. For example, GraphQL Engine can execute a query like

query {
  articles {
    title
  }
  weather {
    temperature
  }
}

where the articles are fetched from the database, and the weather is fetched from a remote server.

Support tracking VOLATILE SQL functions as mutations. (closing #1514)

Previously we could only track STABLE or IMMUTABLE functions, and only as queries. Now the version 2 of track_table also supports tracking functions as mutations:

  {
    "type": "track_function",
    "version": 2,
    "args": {
        "function": {
            "schema": "public",
            "name": "some_volatile_function"
        },
        "configuration": {
            "exposed_as": "mutation"
        }
      }
    }

Remote schema permissions

Now, permissions can be configured for remote schemas as well, which works similar to the permissions system of the postgres tables. Fields/arguments can be removed from the schema and arguments can also be preset to limit the role from having unrestricted access over it.

NOTE: To enable remote schema permissions, the graphql-engine needs to be started either with the server flag --enable-remote-schema-permissions or the environment variable HASURA_GRAPHQL_ENABLE_REMOTE_SCHEMA_PERMISSIONS set to true.

Function Permissions

Before volatile functions were supported, the permissions for functions were automatically inferred from the select permission of the target table. Now, since volatile functions are supported we can't do this anymore, so function permissions are introduced which will explicitly grant permission to a function for a given role. A pre-requisite to adding a function permission is that the role should have select permissions to the target table of the function.

`ltree` comparison operators

Comparison operators on columns with ltree, lquery or ltxtquery types are now supported, for searching through data stored in a hierarchical tree-like structure.

See the documentation at graphql/core/queries/query-filters more details on the currently supported ltree operators.

Example query: Select ancestors of an ltree argument

query {
  tree (
    where: {path: {_ancestor: "Tree.Collections.Pictures.Astronomy.Astronauts"}}
  ) {
    path
  }
}

Example response:

{
  "data": {
    "tree": [
      {
        "path": "Tree"
      },
      {
        "path": "Tree.Collections"
      },
      {
        "path": "Tree.Collections.Pictures"
      },
      {
        "path": "Tree.Collections.Pictures.Astronomy"
      },
      {
        "path": "Tree.Collections.Pictures.Astronomy.Astronauts"
      }
    ]
  }
}

Breaking changes

This release contains the PDV refactor (#4111), a significant rewrite of the internals of the server, which did include some breaking changes:
- The semantics of explicit null values in where filters have changed according to the discussion in issue 704: an explicit null value in a comparison input object will be treated as an error rather than resulting in the expression being evaluated to True. For instance: delete_users(where: {id: {_eq: $userId}}) { name } will yield an error if $userId is null instead of deleting all users.
- The validation of required headers has been fixed (closing #14 and #3659):
  - if a query selects table bar through table foo via a relationship, the required permissions headers will be the union of the required headers of table foo and table bar (we used to only check the headers of the root table);
  - if an insert does not have an on_conflict clause, it will not require the update permissions headers.
This release contains the remote schema permissions feature, which introduces a breaking change:

Earlier, remote schemas were considered to be a public entity and all the roles had unrestricted access to the remote schema. If remote schema permissions are enabled in the graphql-engine, a given remote schema will only be accessible to a role ,if the role has permissions configured for the said remote schema and be accessible according to the permissions that were configured for the role.

v1.3.3

Server - Support for mapping session variables to default JWT claims

Some auth providers do not let users add custom claims in JWT. In such cases, the server can take a JWT configuration option called claims_map to specify a mapping of Hasura session variables to values in existing claims via JSONPath or literal values.

Example:-

Consider the following JWT claim:

  {
    "sub": "1234567890",
    "name": "John Doe",
    "admin": true,
    "iat": 1516239022,
    "user": {
      "id": "ujdh739kd",
      "appRoles": ["user", "editor"]
    }
  }

The corresponding JWT config can be:

  {
    "type":"RS512",
    "key": "<The public Key>",
    "claims_map": {
      "x-hasura-allowed-roles": {"path":"$.user.appRoles"},
      "x-hasura-default-role": {"path":"$.user.appRoles[0]","default":"user"},
      "x-hasura-user-id": {"path":"$.user.id"}
    }
  }

Metadata Types SDK

The types and documentation comments for Metadata V2 have been converted into JSON/YAML Schema, and used to autogenerate type definitions for popular languages.

This enables users to build type-safe tooling in the language of their choice around Metadata interactions and automations.

Additionally, the JSON/YAML Schemas can be used to provide IntelliSense and autocomplete + documentation when interacting with Metadata YAML/JSON files.

For a more comprehensive overview, please see the readme located here

Sample Code

import { TableEntry } from "../generated/HasuraMetadataV2";

const newTable: TableEntry = {
  table: { schema: "public", name: "user" },
  select_permissions: [
    {
      role: "user",
      permission: {
        limit: 100,
        allow_aggregations: false,
        columns: ["id", "name", "etc"],
        computed_fields: ["my_computed_field"],
        filter: {
          id: { _eq: "X-Hasura-User-ID" },
        },
      },
    },
  ],
};

IntelliSense Example

Breaking changes

PDV

This release contains the PDV refactor (#4111), a significant rewrite of the internals of the server, which did include some breaking changes:

The semantics of explicit null values in where filters have changed according to the discussion in issue 704: an explicit null value in a comparison input object will be treated as an error rather than resulting in the expression being evaluated to True. For instance: delete_users(where: {id: {_eq: $userId}}) { name } will yield an error if $userId is null instead of deleting all users.
The validation of required headers has been fixed (closing #14 and #3659):
- if a query selects table bar through table foo via a relationship, the required permissions headers will be the union of the required headers of table foo and table bar (we used to only check the headers of the root table);
- if an insert does not have an on_conflict clause, it will not require the update permissions headers.

Remote Relationship

In this release, a breaking change has been introduced:

In a remote relationship query, the remote schema will be queried when all of the joining arguments are not null values. When there are null value(s), the remote schema won't be queried and the response of the remote relationship field will be null. Earlier, the remote schema was queried with the null value arguments and the response depended upon how the remote schema handled the null arguments.

Relay

The Hasura GraphQL Engine serves Relay schema for Postgres tables which has a primary key defined.

The Relay schema can be accessed through /v1beta1/relay endpoint.

[Add docs links][add console screenshot for relay toggle]

Remote Joins

Remote Joins extend the concept of joining data across tables, to being able to join data across tables and remote schemas.

It works similar to table relationships. Head to the Relationship tab in your table page and define a remote relationship:

give a name for the relationship
select the remote schema
give the join configuration from table columns to remote schema fields.

[Add docs links][add console screenshot]

Scheduled Triggers

A scheduled trigger can be used to execute custom business logic based on time. There are two types of timing events: cron based or timestamp based.

A cron trigger will be useful when something needs to be done periodically. For example, you can create a cron trigger to generate an end-of-day sales report every weekday at 9pm.

You can also schedule one-off events based on a timestamp. For example, a new scheduled event can be created for 2 weeks from when a user signs up to send them an email about their experience.

[Add docs links][add console screenshot]

(close #1914)

Allow access to session variables by computed fields (fix #3846)

Sometimes it is useful for computed fields to have access to the Hasura session variables directly. For example, suppose you want to fetch some articles but also get related user info, say likedByMe. Now, you can define a function like:

CREATE OR REPLACE FUNCTION article_liked(article_row article, hasura_session json)
RETURNS boolean AS $$
  SELECT EXISTS (
    SELECT 1
    FROM liked_article A
    WHERE A.user_id = hasura_session ->> 'x-hasura-user-id' AND A.article_id = article_row.id
  );
$$ LANGUAGE sql STABLE;

and make a query like:

query {
  articles {
    title
    content
    likedByMe
  }
}

Support for this is now added through the add_computed_field API.

Read more about the session argument for computed fields in the docs.

Manage seed migrations as SQL files

A new seeds command is introduced in CLI, this will allow managing seed migrations as SQL files

Creating seed

# create a new seed file and use editor to add SQL content
hasura seed create new_table_seed

# create a new seed by exporting data from tables already present in the database
hasura seed create table1_seed --from-table table1

# create from data in multiple tables:
hasura seed create tables_seed --from-table table1 --from-table table2

Applying seed

# apply all seeds on the database:
hasura seed apply

# apply only a particular seed
hasura seed apply --file 1234_add_some_seed_data.sql

Additional changelog:

CLI: Support servers with self-signed certificates (close #4564) (#4582)

A new flag --certificate-authority is added so that the CA certificate can be provided to trust the Hasura Endpoint with a self-signed SSL certificate.

Another flag --insecure-skip-tls-verification is added to skip verifying the certificate in case you don't have access to the CA certificate. As the name suggests, using this flag is insecure since verification is not carried out.

`v1.2.0-beta.5`

server: backend only insert permissions

Introduces optional backend_only (default: false) configuration in insert permissions (see api reference). If this is set to true, the insert mutation is accessible to the role only if the request is accompanied by x-hasura-use-backend-only-permissions session variable whose value is set to true along with the x-hasura-admin-secret header. Otherwise, the behavior of the permission remains unchanged.

This feature is highly useful in disabling insert_table mutation for a role from frontend clients while still being able to access it from a Action webhook handler (with the same role).

(rfc #4120) (#4224)

server: debugging mode for non-admin roles

For any errors the server sends extra information in extensions field under internal key. Till now this was only available for admin role requests. To enable this for other roles, start the server with --dev-mode flag or set HASURA_GRAPHQL_DEV_MODE env variable to true:

$ graphql-engine --database-url <database-url> serve --dev-mode

In case you want to disable internal field for admin role requests, set --admin-internal-errors option to false or or set HASURA_GRAPHQL_ADMIN_INTERNAL_ERRORS env variable to false

$ graphql-engine --database-url <database-url> serve --admin-internal-errors false

This feature come in handy during development when you may want to see detailed errors irrespective of roles.

Improved internal errors for Actions:

(This is a breaking change with previous 1.2.0-beta releases)

The internal field for action errors is improved with more debug information. It now includes request, response and error fields instead of just webhook_response field.

Before:

{
  "errors": [
    {
      "extensions": {
        "internal": {
          "webhook_response": {
            "age": 25,
            "name": "Alice",
            "id": "some-id"
          }
        },
        "path": "$",
        "code": "unexpected"
      },
      "message": "unexpected fields in webhook response: age"
    }
  ]
}

After:

{

    {
      "extensions": {
        "internal": {
          "error": "unexpected response",

cli: add support for .env file

ENV vars can now be read from .env file present at the project root directory. A global flag, --envfile, is added so you can explicitly provide the .env filename, which defaults to .env filename if no flag is provided.

Example:

hasura console --envfile production.env

The above command will read ENV vars from production.env file present at the project root directory.

console: allow setting post-update check in update permissions

Along with the check for filtering rows that can be updated, you can now set a post-update permission check that needs to be satisfied by the updated rows after the update is made.

console: support for Postgres materialized views

Postgres materialized views are views that are persisted in a table-like form. They are now supported in the Hasura Console, in the same way as views. They will appear on the 'Schema' page, under the 'Data' tab, in the 'Untracked tables or views' section.

console: manage Postgres check constraints

Postgres Check constraints allows you to specify that the value in a certain column must satisfy a Boolean (truth-value) expression. They can be used to put in simple input validations for mutations and with this release, these constraints can now be added while creating a table or later from Modify tab on the console.

Example: When a product is created, ensure that the price is greater than zero. The SQL would look like this:

CREATE TABLE products (
    product_id UUID DEFAULT gen_random_uuid(),
    name TEXT,
    price NUMERIC CONSTRAINT positive_price CHECK (price > 0)
);

To create this table with Hasura Console, on the 'Add a new table' screen, after adding all the columns, scroll down to 'Check constraints' section and 'Add a new check constraint' with the following properties:

Constraint name: positive_price
Check expression: price > 0

CLI: V2 migrations architecture

A new CLI migrations image is introduced to account for the new migrations workflow. If you're have a project with version: 2 in config.yaml, you should use the new image: hasura/graphql-engine:v1.2.0-cli-migrations-v2. Mount the migrations at /hasura-migrations and metadata at /hasura-metadata.

`v1.2.0-beta.1`

Hasura Actions

Actions are a way to extend Hasura’s auto-generated mutations with entirely custom ones which can handle various use cases such as data validation, data enrichment from external sources and any other complex business logic.

A new mutation can be created either by defining its GraphQL SDL or by deriving it from an existing Hasura-generated mutation. The resolver is exposed to Hasura as a webhook which can be called synchronously or asynchronously. This release also includes an ever evolving codegen workflow to make managing the custom resolvers easier.

Downgrade command

A new command is added to the server executable for downgrading to earlier releases. Previously, if you ran a newer Hasura version and wanted to go back to an old version on the same database, you had to stop Hasura, run some SQL statements and start Hasura again. With the new downgrade command, these SQL statements can be run automatically.

Example: Downgrade from v1.2.0 to v1.0.0:

# stop hasura v1.2.0

# run the following command:
docker run hasura/graphql-engine:v1.2.0 graphql-engine --database-url <db-url> downgrade --to-v1.0.0

# start hasura v1.0.0

Read more about this command in the docs.

(close #1156) (#3760)

Expiration of connections authenticated by WebHooks

When using webhooks to authenticate incoming requests to the GraphQL engine server, it is now possible to specify an expiration time; the connection to the server will be automatically closed if it's still running when the expiration delay is expired.
