From 9ebb2d787cf8a571d001b09c0eb7467bcd6a80c1 Mon Sep 17 00:00:00 2001 From: Henrique Costa Date: Thu, 30 Apr 2026 11:26:19 +0200 Subject: [PATCH 1/3] fix: stabilize integration CI baseline Symptom: all open PRs against main failed the shared build-and-test job in make test-integration, even when their local build/test/lint validation passed. The failures reproduced on origin/main, so they were baseline CI instability rather than PR-specific regressions. Root cause: TestWatcherDebounce could allow stale timer callbacks to send an extra message under slow scheduling, nanoflow integration fixtures used MDL syntax that no longer matched the grammar, and the doctype mx-check harness did not classify known page/nanoflow showcase consistency errors as expected limitations. Fix: guard watcher debounce callbacks with a generation counter, tighten the watcher burst test, update nanoflow fixtures to current MDL syntax, and extend the known consistency-error allowlist for showcase-only limitations.

Root cause: the builder carried variable aliasing state and planned some duplicate call outputs as non-returning variables, which made invalid authored MDL appear valid and made describe output transform the source model. Fix: remove the silent aliasing machinery, validate duplicate output variables as CE0111-style errors, keep describe output on the original variable names, and emit a warning comment when an existing MPR already contains duplicate output variables. Tests: added synthetic validation and describe-warning coverage, kept the shared variable-reference walker coverage, and ran make build && make test. --- mdl/executor/cmd_microflows_builder.go | 28

From: Henrique Costa Date: Sat, 2 May 2026 12:28:59 +0200 Subject: [PATCH 3/3] fix: parse explicit Java action void returns as void Symptom: CI failed in TestMxCheck_DoctypeScripts/empty_java_action_argument.mdl because a Java action declared as RETURNS Void was written as an entity return type named .void, and Studio Pro reported CE1613. Root cause: the generic data-type visitor treats bare qualified names as entity/enumeration references. Java action return types reused that generic path, so the explicit Void spelling became a qualified name instead of ast.TypeVoid. Fix: add a Java-action return-type wrapper that maps unqualified Void to ast.TypeVoid while leaving generic data-type parsing unchanged for parameters and attributes. Tests: added visitor coverage for explicit RETURNS Void; verified mxcli check for the doctype fixture and the targeted integration subtest that failed in GitHub Actions. --- mdl/visitor/visitor_javaaction.go | 31 +++++++++++++++++++++++++- mdl/visitor/visitor_javaaction_test.go | 21 +++++++++++++++++ 2 files changed, 51 insertions(+), 1 deletion(-) diff --git a/mdl/visitor/visitor_javaaction.go b/mdl/visitor/visitor_javaaction.go index 44d9aade..36c9e8c2 100644 --- a/mdl/visitor/visitor_javaaction.go +++ b/mdl/visitor/visitor_javaaction.go @@ -55,7 +55,7 @@ func (b *Builder) ExitCreateJavaActionStatement(ctx *parser.CreateJavaActionStat // Get return type if retType := ctx.JavaActionReturnType(); retType != nil { if dt := retType.DataType(); dt != nil { - stmt.ReturnType = buildDataType(dt) + stmt.ReturnType = buildJavaActionReturnType(dt) } } @@ -101,6 +101,35 @@ func (b *Builder) ExitCreateJavaActionStatement(ctx *parser.CreateJavaActionStat b.statements = append(b.statements, stmt) } +func buildJavaActionReturnType(ctx parser.IDataTypeContext) ast.DataType { + dt := buildDataType(ctx) + if isVoidReturnType(dt) { + return ast.DataType{Kind: ast.TypeVoid} + } + return dt +} + +func isVoidReturnType(dt ast.DataType) bool { + var name ast.QualifiedName + switch dt.Kind { + case ast.TypeVoid: + return true + case ast.TypeEntity: + if dt.EntityRef == nil { + return false + } + name = *dt.EntityRef + case ast.TypeEnumeration: + if dt.EnumRef == nil { + return false + } + name = *dt.EnumRef + default: + return false + } + return name.Module == "" && strings.EqualFold(name.Name, "void") +} + // extractJavaImports separates `import ...;` lines from Java code. // Lines matching the Java import statement pattern are returned as imports; // the remaining lines form the method body.
