[Adding model schema version field](#-model-schema-versions) +2. [Adding type enforcements and removing need to specify `as self`](#type-enforcements--removing-as-self) +3. [Disallowing string literals in user_ids](#disallowing-string-literals-in-user_ids) +4. [Enforcing userset type restrictions](#enforcing-userset-type-restrictions) +5. [Requiring you to specify for which relations you can write tuples with public access (using β€˜`*`’)](#public-access) +6. [Changes in query evaluation behavior with type restrictions](#query-evaluation-behavior-with-type-restrictions) + +To facilitate migration to the new DSL schema, you will need to update tuples that are no longer valid. In particular, all tuples with wildcard (`*` or `user:*`) user field defined with model schema 1.0 MUST be deleted and re-added back. + +#### Model Schema Versions + +Since the changes in the DSL are significant, we have decided to add a schema version to the DSL. The previous version of the DSL’s schema was `1.0`, and the new schema version will be `1.1`. To use the new syntax please add the following to the top of the model: + +``` +model + schema 1.1 +``` + +#### Type Enforcements & Removing as self + +We’ll use the following version 1.0 model and tuples to illustrate the changes we’ll need to make: + +```python +model + schema 1.0 + +type user + +type group + relations + define member as self # `as self` is no longer supported and must be replaced with type restrictions + +type folder + relations + define parent as self + define viewer as self or viewer from parent + +type document + relations + define parent as self + define viewer as self + define can_read as viewer or viewer from parent +``` + +With the above model, we can write tuples like: +```yaml +- user: 'user:bob' + relation: 'member' + object: 'group:sales' +- user: 'folder:sales' + relation: 'parent' + object: 'document:pricing' +- user: 'group:sales#member' + relation: 'viewer' + object: 'folder:sales' +- user: 'user:john' + relation: 'viewer' + object: 'document:pricing' +``` + +Those tuples match the intent of how the model was designed, but without type restrictions (introduced in `1.1`) we can also write tuples that would not make as much sense. For example, we can say that a document is a member of the sales group: +```yaml +- user: 'document:pricing' # This is a valid tuple on schema 1.0, but does not make sense + relation: 'member' + object: 'group:sales' +``` + +To be able to better validate tuples and make the model more readable, version 1.1 requires you to specify type restrictions for all the relations that were previously assignable (e.g. relations defined `as self` in any way), and it removes the `as self` keyword. + +The model above needs to be rewritten as below: + +> Mote: The `as` has also been replaced with `:` to separate the relation name from its definition. + +```python +model + schema 1.1 + +type user + +type group + relations + define member: [user] # Replace `as self` with type restriction: user + +type folder + relations + define parent: [folder] # Replace `as self` with type restriction: folder + define viewer: [user] or viewer from parent # Replace `as self` with type restriction: user + +type document + relations + define parent: [folder] # Replace `as self` with type restriction: folder + define viewer: [user] # Replace `as self` with type restriction: user + define can_read: viewer or viewer from parent +``` + +After making these changes, OpenFGA will start validating the tuples more strictly, for example, you won’t be able to assign a `document` as a member of a `group`. If your application is writing invalid tuples, you’ll start getting errors when invoking the `Write` API. + +## Disallowing String Literals in user_ids + +With version 1.0 models, you could write a tuple where the user id did not specify a type, for example: + +```yaml +- user: 'bob' + relation: 'member' + object: 'group:sales' +``` + +However, with version 1.1 you always need to specify an object, so β€œbob’” is no longer a valid identifier. If you don’t have a type in your model that defines relations for users, you can add a β€˜user’ type with no relations to your model, for example: + +```python +model + schema 1.1 + +type user # Define a user type with no relations +``` +You can then use that type when writing tuples: + +```yaml +- user: 'user:bob' # Specify the user type explicitly + relation: 'member' + object: 'group:sales' +``` + +## Enforcing Userset Type Restrictions + +With the model above, the following tuples will be valid according to the type definitions: + +```yaml +- user: 'user:bob' + relation: 'member' + object: 'group:sales' +- user: 'folder:sales' + relation: 'parent' + object: 'document:pricing' +- user: 'user:john' + relation: 'viewer' + object: 'document:pricing' +``` + +However, the one below will not be valid, as we can’t assign `group:sales#member` to the viewer relationship of a folder. + +```yaml +- user: 'group:sales#member' + relation: 'viewer' + object: 'folder:sales' +``` + +You might think that given `group:sales#member` are actually users, you should still be able to assign it. OpenFGA calls expressions like `group:sales#member` ["usersets"](https://openfga.dev/docs/concepts#what-is-a-user), and with our model we can only assign users. + +The issue is that there are a lot of other usersets that you don't want to be assigned as viewers of a folder. For example, you would not want to add `document:pricing#viewer` as viewers of the folder as conceptually it does not make sense to say β€œevery viewer of this document should be a viewer of this folder”. + +To allow these tuples to be written, you need to specify `group#member` as a valid type for the folder’s viewer relationship. You would want to do the same with the document’s viewer relationship if you want to define that the members of a group can be viewers of a document: + +```python +model + schema 1.1 + +type user + +type group + relations + define member: [user] # Replace `as self` with type restriction: user + +type folder + relations + define parent: [folder] # Replace `as self` with type restriction: folder + define viewer: [user, group#member] or viewer from parent # Replace `as self` with type restriction: user, group#member + +type document + relations + define parent: [folder] # Replace `as self` with type restriction: folder + define viewer: [user, group#member] # Replace `as self` with type restriction: user, group#member + define can_read: viewer or viewer from parent +``` + +You can identify which usersets you need to add by looking at tuples in your store that have the following structure: + +```yaml +- user: 'group:sales#member' + relation: 'viewer' + object: 'folder:sales' +``` + +If you find a tuple like that, you’ll need to add `group#member` in the list of types allowed in the `viewer` relation of the `folder` type. + +## Public Access + +When using version 1.0, you can indicate public access to specific objects by specifying a wildcard user in a relationship to any object, e.g.: + +```yaml +- user: '*' + relation: 'viewer' + object: 'document:pricing' +``` + +When you write the tuple above, all users are granted with the β€œviewer” relationship for the β€œpricing" document. You can write those kinds of tuples for any relation that is in the model. + +In version 1.1 we want to be more explicit about the tuples you can write, so you’ll need to declare in the DSL which relations allow wildcards and for which object types. If we want to let any object of type β€œuser” to be a viewer of a specific document, we’ll need to explicitly define it. + +```python +model + schema 1.1 + +type user + +type document + relations + define viewer: [user, user:*] # Allow any user or wildcard user to be a viewer +``` + +You’ll need to specify `user:*` as the user value in the tuple to enable this: + +```yaml +- user: 'user:*' + relation: 'viewer' + object: 'document:pricing' +``` + +Being explicit about the wildcard type restrictions also lets you model scenarios like β€œall employees can see this document, but not all external users”, β€œall user accounts can access this document, but not service/machine-to-machine accounts”. + +This change implies that you’ll need to change your code to write tuples with this new syntax, and that you’ll need to migrate existing tuples to use the new format. + +You might have 3 kinds of tuples in your model that use β€œ*”, with different migration strategies: + +1. Tuples that have user = β€œ*” + + You would need to retrieve those tuples and write them using the proper type (e.g. `user:*`). To retrieve them, you’ll need to use the Read endpoint, filter on your side the tuples that have `user = β€œ*”`, and call the Write API for each one, with the proper type, e.g: + + ```yaml + - user: 'user:*' + relation: 'viewer' + object: 'document:pricing' + ``` + +2. Tuples that have `user = "employee:*”`, where `employee` is NOT a type that is defined in the new iteration of your model. + + If you have tuples with this format, they will be considered invalid because they don’t have a corresponding type in the model. If you need such a type defined, you’ll need to add it to the model, and the scenario will be similar to the one described below. + +3. Tuples that have `user = β€œuser:*”`, which would mean "the user with user_id = '*'”, where `user` is type that is defined in the new iteration of your model. + + In this case, the meaning of the tuple will change. If you were intending to specify "a user with user id = *", you will need to encode it in a different way instead of using β€œ*”. If you intended to specify β€œevery user has this relationship with this object” then it’s not the way it would have worked with schema version = 1.0, but it will work with version = 1.1. + +> ⚠️ Warning +> If you have any wildcard tuples (i.e., `*` or `user:*`) that were created with model schema 1.0, you _**must**_ delete and re-add these tuples with the appropriate type. This allows OpenFGA to interpret these tuples appropriately with the model schema 1.1 semantics. Failure to delete and re-add may cause OpenFGA to interpret these tuples incorrectly. + +## Query Evaluation Behavior with Type Restrictions + +When you make changes to a model that already has tuples, those tuples might become invalid. Some cases where this can happen are: + +- If you rename/delete a type. +- If you rename/delete a relation. +- If you remove types from the list of allowed types in a relation, including changes for Public Access. +- If OpenFGA introduces a change that makes a tuple invalid. + +In these cases, OpenFGA will not consider those invalid tuples when evaluating queries (check, expand, list-objects, etc). However, after any of the changes above happens, you should delete those tuples as having a large number of invalid tuples will negatively affect performance. + + +## Related Errors + +- [`schema-version-required`](./schema-version-required.md) -

From: Anurag Bandyopadhyay Date: Wed, 24 Jun 2026 09:31:40 +0530 Subject: [PATCH 02/29] refactor(pkg/go/validation): drop go-sdk dependency and remove migration cruft The validation package was the only consumer of github.com/openfga/go-sdk, which the feature branch introduced. Every other pkg/go package (transformer, graph, utils) uses the proto-generated types from openfga/api/proto, which is also what TransformDSLToProto outputs. With validation migrated to proto, go-sdk has no remaining importers, so go mod tidy removes it. - Remove unused strings import and the var _ = strings.Join keep-alive hack - Restore descriptive comments on checkSubsumingUnionMembers / checkRedundantIntersectionMembers stubs explaining what they would check -

There are ~26 raise methods. + +**Recommended approach:** treat `exceptions.ts` as the spec. Go method by +method, copy the JS template string into the Go `Sprintf`, preserving backticks +and argument order. This is mechanical and low-risk once started. + +### 2. Wrong raise method / errorType (semantic, not just text) + +Some Go validators reach for a different error category than the reference. The +clearest case is "relation referenced but not defined": + +- Reference distinguishes: + - `raiseInvalidRelationError` β†’ `` the relation \`x\` does not exist. `` + (a relation referenced in a rewrite that doesn't exist on the type) + - `raiseInvalidTypeRelation` β†’ `` the \`reader\` relation definition on type + \`group\` is not valid: \`reader\` does not exist on \`parent\`... `` + (a `X from Y` where the computed relation is missing on the target type) +- Go currently funnels several of these into a single + `RaiseUndefinedRelation` / `RaiseInvalidRelationError` with a generic + "is not defined on type ... (referenced in ...)" template. + +Fixing class 1 wording is not enough here; the **errorType** and the **choice +of raise method** must match so the fixture's `metadata.errorType` assertion +passes. This requires reading `validate-dsl.ts` around lines 500–600 (the +`from`/computed-relation validation) to mirror which error fires when. + +### 3. Cascading / duplicate errors (error-count mismatch) + +The reference emits **one** error per root cause. The Go validator often emits +several for the same underlying problem.

The reference suppresses the +downstream error once the root error is recorded (a relation that references a +non-existent relation should not *also* be reported as having no entry point β€” +the first error subsumes it). + +Fix is logic, not text: when a relation is already flagged (undefined +reference, etc.), skip the derived entrypoint/cycle complaint for that same +relation.

The canonical JS reference distinguishes three cases via a switch on the version: - empty -> 'schema version required' (schema-version-required) - '1.0' -> 'schema version no longer supported' (schema-version-unsupported) - anything else (0.9, 2.0, ...) -> 'invalid schema X' (invalid-schema) '1.0' is a recognized-but-retired version; '0.9'/'2.0' were never valid. These are semantically different and carry different errorTypes and messages. Changes: - ValidateSchemaVersion now mirrors the reference switch (empty / 1.0 / default) - RaiseInvalidSchemaVersion emits 'invalid schema X' with errorType invalid-schema (previously emitted the 'not supported' wording with the wrong errorType) - add RaiseSchemaVersionUnsupported ('schema version no longer supported') for the 1.0 path, which previously had no dedicated method - RaiseSchemaVersionRequired message aligned to 'schema version required' - update unit tests pinning the old behavior; add a 1.0 retired-version case and a RaiseSchemaVersionUnsupported test Fixes the 'unsupported schema version', 'schema required error', and 'allows extend in modular model' cases in dsl-semantic-validation-cases.yaml. --- pkg/go/validation/error_collector.go | 15 ++++++++++++--- pkg/go/validation/error_collector_test.go | 19 ++++++++++++++++--- pkg/go/validation/schema_validation.go | 12 +++++++++--- pkg/go/validation/schema_validation_test.go | 18 ++++++++++++++++-- pkg/go/validation/yaml_integration_test.go | 4 ++-- 5 files changed, 55 insertions(+), 13 deletions(-) diff --git a/pkg/go/validation/error_collector.go b/pkg/go/validation/error_collector.go index f993f3ff..4119f3df 100644 --- a/pkg/go/validation/error_collector.go +++ b/pkg/go/validation/error_collector.go @@ -213,15 +213,24 @@ func (c *ErrorCollector) RaiseInvalidRelationError(symbol, typeName, relation st c.addError(message, MissingDefinition, symbol, lineIndex, meta, nil) } -// RaiseInvalidSchemaVersion raises an error for invalid schema version. +// RaiseInvalidSchemaVersion raises an error for a schema version that was never +// valid (e.g. "0.9", "2.0").

Cases that also trigger the cycle/entry-point cascade remain blocked on that separate reconciliation. --- pkg/go/validation/error_collector.go | 7 +- pkg/go/validation/error_collector_test.go | 2 +- pkg/go/validation/semantic_validation.go | 111 +++++++++++++++--- pkg/go/validation/semantic_validation_test.go | 8 +- pkg/go/validation/wildcard_validation.go | 12 +- 5 files changed, 105 insertions(+), 35 deletions(-) diff --git a/pkg/go/validation/error_collector.go b/pkg/go/validation/error_collector.go index 21873080..60ae891f 100644 --- a/pkg/go/validation/error_collector.go +++ b/pkg/go/validation/error_collector.go @@ -176,20 +176,21 @@ func (c *ErrorCollector) RaiseNoEntryPoint(symbol, typeName string, meta *Meta, // RaiseInvalidRelationOnTupleset raises an error for invalid relation on tupleset. func (c *ErrorCollector) RaiseInvalidRelationOnTupleset(symbol, typeName, typeDef, relationName, offendingRelation, parent string, lineIndex *int, meta *Meta) { - message := fmt.Sprintf("the relation '%s' is not valid on type '%s'.", offendingRelation, typeDef) + message := fmt.Sprintf("the `%s` relation definition on type `%s` is not valid: `%s` does not exist on `%s`, which is of type `%s`.", + offendingRelation, typeDef, offendingRelation, parent, typeName) c.addError(message, InvalidRelationOnTupleset, symbol, lineIndex, meta, nil) } // RaiseInvalidTypeRelation raises an error for invalid type relation. func (c *ErrorCollector) RaiseInvalidTypeRelation(symbol, typeName, relationName, offendingRelation, offendingType string, lineIndex *int, meta *Meta) { - message := fmt.Sprintf("the relation '%s' does not exist on type '%s'.", offendingRelation, offendingType) + message := fmt.Sprintf("`%s` is not a valid relation for `%s`.", offendingRelation, typeName) c.addError(message, InvalidRelationType, symbol, lineIndex, meta, nil) } // RaiseInvalidType raises an error for invalid type. func (c *ErrorCollector) RaiseInvalidType(symbol, typeName, relation string, meta *Meta, lineIndex *int) { - message := fmt.Sprintf("type '%s' is not defined.", symbol) + message := fmt.Sprintf("`%s` is not a valid type.", symbol) c.addError(message, InvalidType, symbol, lineIndex, meta, nil) } diff --git a/pkg/go/validation/error_collector_test.go b/pkg/go/validation/error_collector_test.go index 676c4274..a9ed5844 100644 --- a/pkg/go/validation/error_collector_test.go +++ b/pkg/go/validation/error_collector_test.go @@ -213,7 +213,7 @@ func TestErrorCollector_RaiseInvalidType(t *testing.T) { errors := collector.GetErrors() assert.Len(t, errors, 1) - assert.Equal(t, "type 'unknown_type' is not defined.", errors[0].Message) + assert.Equal(t, "`unknown_type` is not a valid type.", errors[0].Message) assert.Equal(t, InvalidType, errors[0].Metadata.ErrorType) assert.Equal(t, "unknown_type", errors[0].Metadata.Symbol) } diff --git a/pkg/go/validation/semantic_validation.go b/pkg/go/validation/semantic_validation.go index 108d7d78..e6e2852f 100644 --- a/pkg/go/validation/semantic_validation.go +++ b/pkg/go/validation/semantic_validation.go @@ -60,6 +60,40 @@ func (sv *SemanticValidator) GetRelationUserset(typeName, relationName string) * return nil } +// GetRelationNames returns the names of every relation defined on a type. +func (sv *SemanticValidator) GetRelationNames(typeName string) []string { + relations := sv.relationMap[typeName] + names := make([]string, 0, len(relations)) + for name := range relations { + names = append(names, name) + } + return names +} + +// GetDirectlyAssignableTypes returns the type names a relation is directly +// assignable to, but only when that relation is a single direct assignment +// (i.e. `define r: [a, b]` rather than a rewrite).

The reference performs a single traversal per relation that yields exactly one outcome. Rewrite cycle_detection.go as a faithful port of the reference's hasEntryPointOrLoop: walk the rewrite tree with a per-relation visited set and return {hasEntry, loop}. A relation with no entry point produces one error: - loop reached -> ' is an impossible relation for (potential loop).' - otherwise -> ' is an impossible relation for (no entrypoint).' Both carry errorType relation-no-entry-point; the standalone 'contains a cycle' error and its method are removed. Two correctness fixes uncovered along the way: - Direct-assignment usersets are detected via a type switch on the oneof wrapper (*openfgav1.Userset_This) rather than GetThis() != nil. The DSL transformer emits Userset_This with a nil inner DirectUserset, so GetThis() returns nil and every '[user]' relation was wrongly flagged as impossible. Same fix applied to GetDirectlyAssignableTypes. - GetRelationLineNumber now treats skipIndex as a start offset (search from that line onward), matching the reference's slice-based getRelationLineNumber, and the entry-point caller anchors the search to the type's line so the right 'define' occurrence is found when multiple types share a relation name. Rewrites the cycle-detection unit tests around the single-outcome model.

Symbols containing non-word characters (such as 'user:*') fall back to a substring search. - RaiseInvalidType resolves its column to the assignable-types list after the colon, so when a relation and its restriction share a name (define customer: [customer]) the error marks the type, not the relation key. - GetConditionLineNumber matches the 'condition ' declaration rather than any line containing the name as a substring, and treats skipIndex as a start offset like the other line lookups.

What this repo is - -`github.com/openfga/language` is a **multi-language** toolkit for the OpenFGA DSL (the authorization-model language). The single source of truth is the ANTLR grammar at the repo root: - -- `OpenFGALexer.g4`, `OpenFGAParser.g4` β€” grammar. **Change these and you must regenerate parsers for all three languages.** -- `pkg/go`, `pkg/js`, `pkg/java` β€” three independent implementations that must stay behaviour-compatible. -- `tests/data/` β€” **shared** YAML/JSON fixtures consumed by all three implementations. This is the cross-language contract. - -Each `pkg/` is released independently (see Β§9). - -### Feature parity matrix (the important asymmetry) - -| Feature | Go | JS | Java | -|---|---|---|---| -| DSL↔JSON transformer | βœ“ | βœ“ | βœ“ | -| Syntactic validation | βœ“ | βœ“ | βœ“ | -| Semantic validation | βœ— (issue #99) | βœ“ | βœ“ | -| **Graph utilities** | **βœ“ (Go ONLY)** | βœ— | βœ— | - -**The graph package is Go-only and has no sibling implementation to cross-check against.** That is the single most important fact for you. There is no JS/Java reference for graph behaviour β€” the Go tests *are* the spec. - ---- - -## 2. The graph package is load-bearing for the OpenFGA server - -`pkg/go/graph/` is consumed directly by `github.com/openfga/openfga` (the main server) for its **typesystem, Check, and ListObjects** algorithms. Per `AGENTS.md`: - -- Breaking changes here can break core authorization in production. -- Always run `go test ./graph/... -v` and consider how the change lands in the server before merging. -- Treat the exported surface (`Get*`, `Weighted*`, node/edge types) as a **public API**. Renames/signature changes are breaking even when "just a cleanup." - -There is already a concrete example of API-compat care in the code: `GetEdgesFromNodeId` is kept as a `// Deprecated:` shim that forwards to `GetEdgesFromNodeID` (`weighted_graph.go:40`). Follow that pattern β€” don't delete exported methods, deprecate and forward. - -> **Commit `refactor(pkg/go/...)!` β‡’ breaking.** The `!` and a `BREAKING CHANGE:` footer drive a major (or pre-1.0 minor) bump via release-please. See git history e.g. `7fd286c refactor(pkg/go/transformer)!`. - ---- - -## 3. Two different "graphs" β€” don't confuse them - -There are **two parallel, mostly independent** graph implementations in the same package. This is the #1 source of confusion. - -### A. `AuthorizationModelGraph` ("plain graph") β€” `graph.go`, `graph_node.go`, `graph_edge.go`, `graph_builder.go` - -- Built with **gonum** (`gonum.org/v1/gonum/graph/multi.DirectedGraph`). It embeds a gonum multigraph and leans on gonum for topology (`topo.PathExistsIn`, `topo.DirectedCyclesIn`). -- Entry point: `NewAuthorizationModelGraph(model) (*AuthorizationModelGraph, error)`. -- Purpose: structural reachability + visualization. Key methods: `PathExists`, `Reversed`, `GetCycles`, `GetDOT`, `GetNodeByLabel`. -- Node lookup is by **label** through an `ids map[string]int64` (`NodeLabelsToIDs`). gonum assigns numeric IDs; this map is how you go labelβ†’idβ†’node in O(1). -- **No weights.** Conditions are tracked on edges but "Conditions are not encoded in the graph" for traversal purposes. - -### B. `WeightedAuthorizationModelGraph` ("weighted graph") β€” `weighted_graph.go`, `weighted_graph_node.go`, `weighted_graph_edge.go`, `weighted_graph_builder.go` - -- **Does NOT use gonum for storage.** It is hand-rolled: two plain maps, - ```go - nodes map[string]*WeightedAuthorizationModelNode // keyed by uniqueLabel - edges map[string][]*WeightedAuthorizationModelEdge // keyed by from-node uniqueLabel (adjacency list) - ``` - (The *builder* `WeightedAuthorizationModelGraphBuilder` embeds a gonum multigraph, but the resulting `WeightedAuthorizationModelGraph` it produces uses the maps. Don't be misled by the embed.) -- Entry point: `NewWeightedAuthorizationModelGraphBuilder().Build(model)`. -- Purpose: the **weight** algorithm that the server uses to plan Check/ListObjects (which path is cheapest, recursion detection, etc.). -- This is where ~80% of the package's complexity and line count lives (`weighted_graph.go` ~1250 lines, `weighted_graph_builder.go`, plus ~7000 lines of tests). - -**Gotcha:** the two share `NodeType`, `EdgeType`, operator-name constants, and `DrawingDirection`, but **not** node/edge structs, not the builder, not the storage model. A fix in one is *not* automatically reflected in the other. When you change graph-building logic, check whether the same logic exists (duplicated) in both `graph_builder.go` and `weighted_graph_builder.go` β€” the parsing functions (`parseThis`, `parseComputed`, `parseTupleToUserset`, `checkRewrite`/`parseRewrite`) are near-duplicates with subtle differences. - ---- - -## 4. Graph vocabulary (NodeType / EdgeType) - -Defined in `weighted_graph_node.go` and `weighted_graph_edge.go`. You will read these constantly. - -**NodeType:** -| Const | Meaning | Example | -|---|---|---| -| `SpecificType` | a type | `group` | -| `SpecificTypeAndRelation` | a relation on a type | `group#member` | -| `OperatorNode` | union/intersection/exclusion | label is `"union"`/`"intersection"`/`"exclusion"` | -| `SpecificTypeWildcard` | typed wildcard | `group:*` | -| `LogicalDirectGrouping` | grouping of multiple direct assignments under an operator | `[user, employee, type1#rel]` | -| `LogicalTTUGrouping` | grouping of a TTU with multiple possible parent types | `member from parent` where `parent` has several types | - -**EdgeType:** -| Const | Meaning | -|---|---| -| `DirectEdge` | direct assignment `define rel: [user]` | -| `RewriteEdge` | operatorβ†’relation, or relationβ†’operator wiring | -| `TTUEdge` | tuple-to-userset `define rel: admin from parent` | -| `ComputedEdge` | `define rel1: rel2` (relationβ†’relation) | -| `DirectLogicalEdge` | operatorβ†’`LogicalDirectGrouping` | -| `TTULogicalEdge` | operatorβ†’`LogicalTTUGrouping` | - -### Operator-node uniqueness gotcha β€” ULIDs -Operator nodes get a **unique label built from a fresh ULID**: `fmt.Sprintf("%s:%s", operator, ulid.Make().String())` (`graph_builder.go:109`, `weighted_graph_builder.go:93`). So `union:01J54...`. This means: -- `label` (e.g. `"union"`) is *not* unique; `uniqueLabel` is. -- **`ulid.Make()` is nondeterministic** (it embeds a timestamp + randomness). The graph is deliberately built with **types and relations sorted** (`slices.SortFunc` by type name, `slices.Sort` on relations) so that *structure* is stable, but the ULID strings on operator nodes are NOT stable across runs. **Never assert on the exact ULID in a test or snapshot** β€” match on `label`/structure instead. `GetDOT()` output is "stable" only in structure, and the doc comment says it's for debugging only. - -### `LogicalDirectGrouping` / `LogicalTTUGrouping` β€” the "only when >1 child under an operator" rule -These grouping nodes are created **only** when a direct-assignment list or a multi-parent TTU appears as a child of an operator node AND there is more than one related type. Read the conditions carefully: - -- `parseThis` (weighted, `weighted_graph_builder.go:185`): grouping node created only if `parentNode.nodeType != SpecificTypeAndRelation && len(directlyRelated) > 1`. I.e. directly on a relation (`define rel: [a,b,c]`) β†’ three direct edges straight off the relation node, **no** grouping node. Inside an `or`/`and`/`but not` β†’ grouping node. -- The edge-type comments explicitly note that **under a `not`/exclusion the grouping node is intentionally NOT created** to avoid unnecessary nesting. - -If you add/inspect grouping logic, this asymmetry (relation-level vs operator-level, and the not-operator exception) is the thing to keep straight. - ---- - -## 5. The weight algorithm (`weighted_graph.go`) β€” the deep end - -This is the hardest code in the repo. High-level model: - -- A node's `weights` is a `map[string]int` from **terminal type** (e.g. `"user"`) to an integer weight (roughly path length / cost), where `Infinite = math.MaxInt32` signals recursion. -- `AssignWeights()` is the driver. It walks nodes, computing edge weights then node weights bottom-up. - -### Key invariants & traps - -1. **Operator/logical nodes are deferred.** `AssignWeights` *skips* operator and logical nodes in its first pass (`weighted_graph.go:227`, `isLogicalOperator`) and resolves them later in `fixDependantNodesWeight`. The comment says this is "for more deterministic behavior." Don't "optimize" by computing them inline β€” order matters here. - -2. **Three weight-combination strategies, chosen by operator:** - - `calculateNodeWeightWithMaxStrategy` β€” used for non-operator nodes and **Union**. A type is valid if it appears in *any* branch β†’ take max. - - `calculateNodeWeightWithEnforceTypeStrategy` β€” **Intersection (AND)**. A type is valid only if it appears in *all* branches β†’ intersect keys, drop any key missing from a branch. **If the result is empty β†’ `ErrInvalidModel` ("not all paths return the same type").** - - `calculateNodeWeightWithMixedStrategy` β€” **Exclusion (A but not B)**. `A` is max; `B` only constrains types already in `A`. Asserts exactly 2 edges. - -3. **Cycle classification is central.** `isTupleCycle` (`weighted_graph.go:546`) distinguishes: - - **Model cycle** (`ErrModelCycle`): a pure computed/rewrite cycle with no TTU or userset edge β†’ the model is invalid, would stack-overflow at Check time regardless of tuples. - - **Tuple cycle** (`ErrTupleCycle`): cycle goes through a `TTUEdge` or a `DirectEdge` into a `SpecificTypeAndRelation` β†’ can only cycle *if tuples exist*. This is allowed (weight becomes `Infinite`), and tracked via `recursiveRelation` / `tupleCycle` metadata on nodes+edges. - - **`ErrContrainstTupleCycle`**: AND/BUT-NOT operands cannot be part of a tuple cycle β†’ invalid model. - -4. **`R#` reference keys.** During cycle handling, weights temporarily carry keys prefixed `"R#"` + nodeID (e.g. `R#group#member`) meaning "this weight depends on resolving the cycle rooted at that node." `calculateNodeWeightAndFixDependencies` + `fixDependantEdgesWeight` + `fixDependantNodesWeight` later substitute the real weights and strip the `R#` placeholders. If you ever see `R#...` leaking into a final node's `weights`, the dependency-fix pass didn't run / a cycle wasn't rooted correctly. That's a bug, not expected output. - -5. **`tupleCycleDependencies map[string][]*edge`** is the bookkeeping that lets the algorithm fix all edges/nodes that pointed at a cycle once the cycle's root is resolved. The "responsible node" (`isNodeTupleCycleReference`) is the one that fixes and then `removeNodeFromTupleCycles`. - -6. **Userset weights are computed lazily and cached in `sync.Map`.** `getWeightForUserset` / `GetEdgeWeight` compute weights for `type#relation` keys on demand and cache them in `node.usersetWeights` / `edge.usersetWeights` (both `sync.Map`). This is why those fields are `sync.Map` and not plain maps β€” see Β§6 on concurrency. There's an "early pruning" check before traversal (`weighted_graph.go:333`) using the rule that a direct edge adds +1, so a reachable userset must have weight strictly greater (unless `Infinite`). - -7. **`directAssigns` on a node** is a flat list of the unique labels a relation can be directly assigned (filled in `parseThis`). It exists so the server can answer "is this write/contextual tuple valid?" in O(1). `GetDirectEdgesAssignation` / `GetDirectEdgeForUserType` reconstruct the actual edges, which is non-trivial because direct edges may sit under a `LogicalDirectGrouping` or deeper under operator nodes (hence the traversal loops). - -**Practical advice:** before touching the weight algorithm, read the tests first (`weighted_graph_test.go`, `weighted_graph_builder_test.go`, `weighted_graph_userset_test.go`). They encode the intended weights for dozens of model shapes and are far more readable than the algorithm itself. Add a failing test that captures your case, *then* change code. - ---- - -## 6. Concurrency gotcha (graph) - -`WeightedAuthorizationModelNode` and `WeightedAuthorizationModelEdge` contain `usersetWeights sync.Map`. The server calls weight queries concurrently, so: - -- **Read-only query methods may still mutate** (they populate the `sync.Map` cache). That's intentional and the `sync.Map` makes it safe. -- **The maps `nodes`/`edges` themselves are NOT synchronized.** They are populated during `Build`/`AssignWeights` and then treated as immutable.

It is **not reusable / not concurrency-safe** β€” `newOpenFgaDslListener()` per parse. The `rewriteStack` is how nested `or`/`and`/`but not` expressions are assembled (`ParseExpression`). -- **Proto, not hand-rolled JSON.** Models are `openfgav1.AuthorizationModel` from `github.com/openfga/api/proto`. JSON conversion goes through `protojson`, not `encoding/json`. If a field "disappears" in JSON, suspect proto field names / `protojson` casing, not your code. -- **Errors are user-facing and line/column-aware.** Syntax errors come from `OpenFgaDslErrorListener` and are matched character-for-character by the shared fixtures (see Β§8). Changing an error string is a cross-language contract change. -- **`MustTransform*` panic.** Only use in tests / where input is known-good. - ---- - -## 8. Shared test fixtures β€” the cross-language contract - -`tests/data/` (at repo root, three levels up from `pkg/go/transformer`) holds YAML/JSON cases used by Go, JS, and Java. The Go side loads them with relative paths like `filepath.Join("../../../tests", "data", "transformer")` (`transformer/testcases_test.go:70`). - -Files you'll touch: -- `transformer/`, `transformer-module/` β€” DSL↔JSON case dirs. -- `dsl-syntax-validation-cases.yaml`, `json-syntax-transformer-validation-cases.yaml`, `dsl-semantic-validation-cases.yaml`, `json-validation-cases.yaml`, `fga-mod-transformer-cases.yaml`. -- `stores/` β€” store-level fixtures. - -**Gotchas:** -- A test case has a `Skip` flag (`validTestCase.Skip`) β€” used to land a fixture before all three languages implement it. If you add a case Go can't yet handle but JS can, you may need to coordinate skips across languages. -- These fixtures are linted with **prettier** (`make lint-tests`, run from `pkg/js`). A fixture-only change can fail CI on formatting. Run `make format-tests` before pushing. -- **Adding a fixture affects JS and Java CI too.** A "Go change" that edits shared fixtures is really a three-language change. If you only intend to change Go behaviour, prefer a Go-only test (e.g. in `graph/`) over editing shared fixtures. -- Error-case fixtures match the *exact* error string and line/column. See `GetErrorString()` in `testcases_test.go` for the format the Go side expects (`N error(s) occurred:\n\t* syntax error at line=L, column=C: msg`). - ---- - -## 9. Build, generate, lint, release - -### ANTLR generation needs Docker -- `make antlr-gen-go` (and `-js`, `-java`) run an **ANTLR Docker container** (`make build-antlr-container`). You cannot regenerate parsers without Docker. -- Generated code lives in `pkg/go/gen/` (`openfga_parser.go`, `openfga_lexer.go`, listeners, `.tokens`, `.interp`). **Never hand-edit `gen/`.** Edit the `.g4` files at the repo root, then regenerate. -- Most `make` targets depend on `antlr-gen-*` first, so a normal `make build-go` will try to invoke Docker. If you only changed Go source (not grammar), you can work inside `pkg/go` directly with plain `go` commands to skip Docker (see below). - -### Day-to-day Go commands (from `pkg/go/`, no Docker needed) -```bash -go build ./... -go test ./... -count=1 -race # == make test (note: -race always) -go test ./graph/... -v # graph only -go test ./transformer/... -run TestDslToJson -v -``` -Or via root Makefile (these prepend antlr-gen β†’ Docker): -- `make test-go`, `make lint-go` (golangci-lint **with --fix**), `make audit-go` (govulncheck), `make format-go` (gofumpt β€” only formats `transformer/` and `errors/`, per the Makefile). - -**Gotcha:** `make lint-go` runs `golangci-lint --fix`, which **modifies your files**. Don't be surprised by working-tree changes after linting. Config is `.golangci.yaml`. - -**Gotcha:** `go.mod` is `go 1.25.0`.

The Go validator in `pkg/go/validation/` is a port -of it. Both are exercised against the **same shared fixture file**: - -``` -tests/data/dsl-semantic-validation-cases.yaml (82 semantic cases) -``` - -Each case pins an exact expected error: message text, error count, line/column, -symbol, and `errorType`. The Go integration harness -(`yaml_test_integration.go` / `yaml_integration_test.go`) loads these cases, -runs `ValidateDSL`, and compares actual errors against expected. - -As of this writing the Go validator passes **6 / 82** of those cases. The -remaining ~76 fail almost entirely on **error-message wording and error -count** β€” not on whether a problem is detected. The validator usually finds the -right issue; it describes it in different words, or emits extra cascading errors -the reference does not. - -> Note: today these mismatches do **not** fail `go test`. The harness logs -> `FAIL` via `t.Logf` and never calls `t.Fail()`.

There are ~26 raise methods. - -**Recommended approach:** treat `exceptions.ts` as the spec. Go method by -method, copy the JS template string into the Go `Sprintf`, preserving backticks -and argument order. This is mechanical and low-risk once started. - -### 2. Wrong raise method / errorType (semantic, not just text) - -Some Go validators reach for a different error category than the reference. The -clearest case is "relation referenced but not defined": - -- Reference distinguishes: - - `raiseInvalidRelationError` β†’ `` the relation \`x\` does not exist. `` - (a relation referenced in a rewrite that doesn't exist on the type) - - `raiseInvalidTypeRelation` β†’ `` the \`reader\` relation definition on type - \`group\` is not valid: \`reader\` does not exist on \`parent\`... `` - (a `X from Y` where the computed relation is missing on the target type) -- Go currently funnels several of these into a single - `RaiseUndefinedRelation` / `RaiseInvalidRelationError` with a generic - "is not defined on type ... (referenced in ...)" template. - -Fixing class 1 wording is not enough here; the **errorType** and the **choice -of raise method** must match so the fixture's `metadata.errorType` assertion -passes. This requires reading `validate-dsl.ts` around lines 500–600 (the -`from`/computed-relation validation) to mirror which error fires when. - -### 3. Cascading / duplicate errors (error-count mismatch) - -The reference emits **one** error per root cause. The Go validator often emits -several for the same underlying problem. Example from fixture case 1: - -``` -expected: 1 β†’ the relation `allowed` does not exist. -got: 2 β†’ Relation 'allowed' is not defined on type 'group' (...) - Relation 'reader' on type 'group' has no entry point -``` - -And the no-entrypoint cases routinely emit both `contains a cycle` **and** -`has no entry point` for one relation, where the reference emits a single -`(no entrypoint)` or `(potential loop)`. - -Root cause: the Go semantic phase and cycle/entrypoint phase both fire on the -same broken relation without coordination. The reference suppresses the -downstream error once the root error is recorded (a relation that references a -non-existent relation should not *also* be reported as having no entry point β€” -the first error subsumes it). - -Fix is logic, not text: when a relation is already flagged (undefined -reference, etc.), skip the derived entrypoint/cycle complaint for that same -relation. Look at how `validate-dsl.ts` orders and short-circuits its checks. - -## Suggested order of work - -1. **Class 1 (wording)** first β€” mechanical, unblocks the most fixtures, and - makes the remaining diffs readable. Diff every `raise*` in `exceptions.ts` - against `error_collector.go`. -2. **Class 2 (raise method / errorType)** β€” needs `validate-dsl.ts` reading but - is well-scoped to the `from`/computed-relation and undefined-relation paths. -3. **Class 3 (cascading)** β€” the hardest; requires cross-phase coordination so - one root cause yields one error. Do last, measuring fixture pass-count after - each change. -4. Only once the pass count is high, flip the YAML harness from `t.Logf` to a - real `t.Fail()`/`require` so regressions are caught. - -## How to measure progress - -``` -cd pkg/go -go test ./validation/... -v -run TestYAMLTestRunner_ComprehensiveValidation 2>&1 \ - | grep -E "Total Tests:|Passed:|Failed:" -``` - -Baseline at time of writing: **6 / 82 passing**.

name_validation.go compiled the anchored type/relation/condition name rule for every name. The rules are fixed, so compile them once into a cache keyed by the anchored rule string (which is also the clause reported in the error) and have validateFieldValue serve fixed rules from it. - schema_validation.go recompiled the `\s{2,}` whitespace-collapsing pattern inside the per-line loop; hoist it to a package-level var. - error_collector.go wordIndex compiled `\bsymbol\b` per error to find a symbol's column. The pattern is symbol-dependent, so replace the regexp with a direct word-boundary scan: walk substring matches and accept the first whose flanking characters aren't word characters, falling back to a plain substring search for symbols with non-word characters (e.g. user:*). This keeps identical results without per-call compilation or shared state. TestWordIndex locks the boundary and fallback semantics.

The reference compares each condition's nested name property to its map key (conditionName != condition.name); match that, and update the DifferentNestedConditionName message and symbol to the reference's form ("condition key is `X` but nested name property is Y"). - Condition-reference errors now anchor the relation line lookup to the referencing type's declaration (GetTypeLineNumber -> GetRelationLineNumber), so the correct `define` is found when several types share a relation name. - Wildcard validation likewise anchors its relation line lookups to the type declaration for both the undefined-type and wildcard-with-relation reports.
