Previously, only 5 declarations were parsed +(Accumulator, Template, Output, Mode, Function); the remaining 13 caused +immediate hard errors that prevented the entire stylesheet from compiling. + +Now all declarations are parsed into the AST. Declarations that lack full +compiler support are gracefully skipped instead of aborting, allowing +stylesheets that *contain* unsupported declarations to still process their +templates. + +## Test Results + +| Metric | Before | After | Delta | +|--------|--------|-------|-------| +| Passed | 1,129 | 1,178 | **+49** | +| Failed | 604 | 738 | +134 | +| Error | 12,831 | 12,585 | **-246** | +| "Unsupported declaration" errors | ~9,003 | 37 | **-8,966** | + +The +134 in "Failed" is actually progress — those tests now compile and run +but produce wrong results (due to skipped declarations like global variables), +rather than aborting outright. This makes them visible for future work. + +## Changes + +### 1. AST: `From for Declaration` implementations (`xee-xslt-ast/src/ast_core.rs`) + +Added `From for Declaration` trait implementations for 13 types that were +missing them: + +- `CharacterMap`, `DecimalFormat`, `GlobalContextItem` +- `Import`, `ImportSchema`, `Include` +- `Key`, `NamespaceAlias` +- `Param`, `PreserveSpace`, `StripSpace` +- `UsePackage`, `Variable` + +These are required for the `DeclarationParser` trait to work (it requires both +`InstructionParser` and `Into`). + +### 2. Parser: Hook up all declarations (`xee-xslt-ast/src/names.rs`) + +Extended `DeclarationName::parse()` from 5 variants to 17 variants. Only +`UsePackage` remains unsupported (no `InstructionParser` implementation exists +for it yet; affects only 37 tests). + +### 3. Compiler: Graceful skip (`xee-xslt-compiler/src/ast_ir.rs`) + +Changed the `declaration()` method from returning `Err(Unsupported(...))` for +unknown declarations to returning `Ok(())` with explicit match arms: + +- **Compiled:** `Template`, `Mode`, `Output` (as before) +- **Pre-processed:** `Import`, `Include` (handled during import resolution) +- **Skipped gracefully:** `Function`, `Variable`, `Param`, `Key`, + `StripSpace`, `PreserveSpace`, `DecimalFormat`, `CharacterMap`, + `NamespaceAlias`, `ImportSchema`, `UsePackage`, `GlobalContextItem`, + `Accumulator` + +### 4. Import cycle detection (`xee-xslt-compiler/src/ast_ir.rs`) + +Added `HashSet` tracking of visited stylesheet paths during +`xsl:import` and `xsl:include` processing. Previously, self-referential or +circular imports caused a stack overflow crash. Now they produce a clear error: +`"Circular import detected: '/path/to/file.xsl'"`. + +## New Error Landscape + +After these changes, the dominant error categories are: + +| Error | Count | Cause | +|-------|-------|-------| +| XPST0008 Name not defined | 4,629 | Global variables/params skipped but referenced | +| Instruction not supported: SourceDocument | 1,677 | Test harness uses `` | +| Failed parsing XSLT: Attribute | 1,352 | Various attribute parsing gaps | +| XPST0017 function not found | 911 | User-defined `xsl:function` not callable from XPath | +| No stylesheet found | 333 | Test runner can't locate stylesheet | + +## Recommended Next Steps + +1. **Global `xsl:variable` / `xsl:param` support** — Would resolve ~4,629 + XPST0008 errors.

Static validation for invalid `xsl:param` declarations +2. Dynamic errors for missing required stylesheet/template parameters +3. Test runner support needed to exercise these semantics correctly + +The implementation does not yet solve parameter propagation for +`xsl:apply-templates`. That remains the next major gap. But it does make the +named-template and global-parameter behavior materially more correct and fixes +several targeted conformance cases. + +## What Was Implemented + +### 1. Static validation for invalid required params + +Added validation in `xee-xslt-compiler/src/ast_ir.rs` so that an `xsl:param` +with `required="yes"` cannot also provide a `select` attribute or child +sequence constructor. + +This now raises `XTSE0010` during compilation instead of silently compiling the +stylesheet. + +Applied to: + +- global `xsl:param` +- template-local `xsl:param` + +### 2. IR now records whether a parameter is required + +Extended `xee-ir/src/ir.rs` so `ir::Param` carries a `required: bool` field. + +This is important because requiredness must survive lowering from XSLT AST into +IR and then into bytecode generation, especially for named templates. + +### 3. Required template params now fail at runtime + +Updated `xee-ir/src/function_compiler.rs` to emit explicit runtime checks for +required parameters that do not have defaults. + +Implementation details: + +- existing default-parameter handling already used `VarIsAbsent` +- required params now also use `VarIsAbsent` +- if the argument is absent, the compiler emits a dedicated bytecode raise path +- the interpreter maps that to `XTDE0700` + +This keeps required-param behavior localized and avoids overloading unrelated +error paths. + +### 4. Required global stylesheet params now fail at runtime + +Updated `xee-interpreter/src/interpreter/interpret.rs` so global stylesheet +params marked `required` now raise `XTDE0050` if no externally supplied value +exists in the dynamic context. + +Before this change, missing required stylesheet params simply fell through and +executed as if no error existed. + +### 5. Named template parameter matching is stricter + +Updated named-template lookup/matching in `xee-ir/src/declaration_compiler.rs` +and `xee-ir/src/function_compiler.rs`. + +Behavior changes: + +- named templates are keyed by stable local-name strings instead of debug + formatting +- `xsl:with-param` names are checked against the declared params of the target + named template +- undeclared non-tunnel params now raise `XTSE0680` + +This fixes cases where `call-template` supplied a parameter the callee never +declared. + +### 6. Added dedicated bytecode support for raising required-param errors + +Added `RaiseError(RaisedError)` to +`xee-interpreter/src/interpreter/instruction.rs` with a current specialized +variant for `XTDE0700`. + +This keeps the runtime implementation simple: + +- compiler emits a specific instruction +- interpreter decodes it and returns the correct XSLT error + +The goal was to avoid a larger general-purpose exception mechanism for this +targeted fix. + +### 7. Test runner now passes stylesheet variables into the dynamic context + +Updated `xee-testrunner/src/testcase/xslt.rs` so XSLT tests actually load the +environment variables and pass them into the program's dynamic context. + +Without this, required global-param tests could not be evaluated correctly, +because externally supplied stylesheet parameters were ignored by the runner. + +### 8. Test runner now honors `initial-template` + +Updated `xee-testrunner/src/testcase/xslt.rs` and +`xee-interpreter/src/interpreter/runnable.rs` so XSLT conformance tests can run +an initial named template instead of always starting from the normal main +template path. + +Implementation details: + +- parse `` from the test definition +- look up the named template in runtime declarations +- invoke it directly through the interpreter +- supply explicit absent placeholders for unsupplied template arguments so + required-param checks run in the callee rather than failing early on arity + +This was necessary for `param-0116` to test the intended behavior. + +### 9. XSLT compile errors are now surfaced as compilation errors in the runner + +Updated `xee-testrunner/src/testcase/xslt.rs` so stylesheet compilation errors +are handled like XPath compilation errors: + +- if the test expects an error, compare against the error code +- otherwise report a compilation error + +Previously these cases were often classified as generic environment errors, +which made static-error conformance checks less meaningful. + +## Files Changed + +### Compiler and IR + +- `xee-xslt-compiler/src/ast_ir.rs` +- `xee-ir/src/ir.rs` +- `xee-ir/src/declaration_compiler.rs` +-

Its focus is +not new error codes, but correctness of variable and parameter binding across +XSLT and shared XPath lowering. + +The main areas improved here are: + +1. lexical scoping for XSLT local variables and params +2. context/focus plumbing for named templates +3. XPath declaration scoping for `let`, `for`, quantified expressions, and + inline function parameters +4. sequence-constructor lowering so `xsl:variable` is handled correctly even + when it does not appear as the first item in a constructor + +This pass fixes a real cluster of declaration failures, especially those that +previously reported internal compiler errors around missing variables or +mis-bound shadowed variables. + +## What Was Implemented + +### 1. Lexical variable scopes in the shared IR variable table + +Updated `xee-ir/src/variables.rs` so variable bindings are no longer stored in +one flat map for the entire conversion pass. + +The `Variables` helper now maintains a stack of lexical scopes and exposes +separate operations for: + +- looking up an existing variable binding +- declaring a fresh local binding in the current scope +- entering and exiting a lexical scope + +This fixes two correctness problems: + +- local variables and params can now shadow outer bindings correctly +- a variable is no longer visible within its own initializer unless an outer + binding of the same name exists + +That matters for both XSLT local variable declarations and the shared XPath IR +converter used to compile expressions inside XSLT instructions. + +### 2. Template-local scopes are isolated between separately compiled templates + +Updated `xee-xslt-compiler/src/ast_ir.rs` so each template compilation pushes a +fresh variable scope before registering its params and lowering its body. + +Before this change, template-local parameter bindings could leak across +templates because the compiler reused the same variable table while compiling +the whole stylesheet. + +The result was a class of bogus internal failures where one template body could +end up referencing a runtime name that had only been declared while compiling a +different template. + +This was visible in cases such as `param-0107`, where the unresolved variable +coming out of lowering was not from the current template at all. + +### 3. Named templates now receive the current focus triple + +Updated the XSLT AST lowering and IR call path so named templates receive the +current focus, matching what matched templates already received. + +Concretely: + +- `xee-ir/src/ir.rs` now records optional call-site context on + `ir::CallTemplate` +- `xee-xslt-compiler/src/ast_ir.rs` captures the current context when lowering + `xsl:call-template` +- named template function definitions now include hidden leading params for: + - current item + - current position + - current size +- `xee-ir/src/declaration_compiler.rs` now registers only the explicit template + params for name validation, skipping those hidden focus params +- `xee-ir/src/function_compiler.rs` passes either the current focus triple or + explicit absent markers when compiling a named-template call + +This fixes named-template bodies and defaults that depend on the current node, +for example template params with defaults such as `select="@id"`. + +### 4. Matched and named template param defaults now compile with the right scope + +The earlier apply-templates work already moved matched-template defaults under a +live context. This pass tightens the surrounding lexical scope handling so both +matched and named templates compile defaults while the correct template-local +bindings are visible and isolated. + +That improves cases where one param default references another param, and cases +where a default references the context item. + +### 5. Sequence constructors now handle `xsl:variable` anywhere, not just first + +Updated `xee-xslt-compiler/src/ast_ir.rs` so sequence-constructor lowering no +longer assumes that only the first item in a constructor might be a variable +declaration. + +Previously: + +- `xsl:variable` was recognized only if it appeared at the head of the current + constructor slice +- a later `xsl:variable` would fall through into normal instruction lowering +- that triggered the internal error path: + `Internal bug: variable node should have been processed already` + +The new recursive lowering handles variable declarations anywhere in the +constructor while still preserving `let` nesting semantics. + +This directly fixed `param-0107`. + +### 6. XPath declaration sites now use real lexical declaration scopes + +Updated `xee-xpath-compiler/src/ast_ir.rs` so XPath declaration forms no longer +use the old “lookup or create” variable registration behavior. + +Adjusted sites include: + +- `let` expressions +- `for` expressions +- quantified expressions +- inline function parameters + +These declaration sites now push a fresh scope, declare their binding names in +that scope, lower the body, and then pop the scope. + +This is necessary because XSLT param and variable expressions can contain XPath +shadowing forms such as: + +```xpath +($y, (for $y in ('x', 'y', 'z') return $y)) +``` + +Without lexical declaration scopes, the inner `$y` could be compiled against +the wrong binding or reuse an outer runtime name. + +## Files Changed + +### IR and Compiler Infrastructure + +- `xee-ir/src/variables.rs` +- `xee-ir/src/ir.rs` +- `xee-ir/src/declaration_compiler.rs` +- `xee-ir/src/function_compiler.rs` + +### XSLT Lowering + +- `xee-xslt-compiler/src/ast_ir.rs` + +### XPath Lowering + +- `xee-xpath-compiler/src/ast_ir.rs` + +## Verification + +### Focused Rust crate tests + +Verified with: + +```bash +cargo test -q -p xee-ir -p xee-interpreter -p xee-xslt-compiler +``` + +Result: all tests passed. + +### Targeted conformance cases rerun during this pass + +Explicitly rerun and confirmed fixed: + +- `param-0107` + +Explicitly rerun and confirmed improved but still not fully correct: + +- `variable-3301` + - no longer fails with an internal compiler error + - now reaches result comparison and fails with an XML mismatch + +### Aggregate conformance snapshot after this change + +`decl/param`: + +- Passed: 13 +- Failed: 0 +- Error: 11 +- WrongE: 7 + +`decl/variable`: + +- Passed: 58 +- Failed: 10 +- Error: 32 +- WrongE: 8 + +Compared to the previous checkpoint, this is a net improvement in both suites, +especially by removing part of the internal-variable-resolution failure class. + +## What This Does Not Yet Solve + +Several known areas remain open: + +1. tunnel-parameter semantics are still incomplete +2. some remaining `decl/variable` failures now show behavioral mismatches rather + than compiler crashes +3. unsupported instruction families such as `next-match`, `apply-imports`, and + `for-each-group` still account for some remaining declaration-suite failures + +One useful sign of progress is that a number of reducers that previously failed +with internal compiler errors now fail later and more specifically, which means +the binding model is materially closer to correct. + +## Commit Readiness + +This is a reasonable checkpoint commit. + +Why it is commit-worthy: + +- it fixes real correctness bugs in shared variable scoping +- it removes a class of internal compiler errors rather than only changing test + outcomes superficially +- focused Rust regression tests are green +- declaration-suite pass counts improved in both `param` and `variable` +- it is logically cohesive with the current XSLT declaration work + +Why it is not a final declaration-semantics commit: + +- tunnel parameters are still incomplete +- some template/application behavior is still wrong even though the compiler no + longer crashes +- several remaining failures are due to still-unsupported XSLT instruction + families + +Suggested commit framing: + +- `Fix XSLT variable scoping and named-template context` +- or `Improve XSLT template param scoping and context binding` + +## Next Step + +The next highest-value target is likely one of: + +1. the tunnel-parameter cluster around tests such as `variable-0203` +2. the remaining behavioral mismatch in `variable-3301` +3. unsupported instruction families that are now standing out more clearly + after the scoping fixes \ No newline at end of file diff --git a/xee-ir/src/declaration_compiler.rs b/xee-ir/src/declaration_compiler.rs index c4667775..fe43755d 100644 --- a/xee-ir/src/declaration_compiler.rs +++ b/xee-ir/src/declaration_compiler.rs @@ -145,7 +145,7 @@ impl<'a> DeclarationCompiler<'a> { let template_name_key = function_binding.name.as_str().to_string();
