From af3ddf9022b1edb6413ed48e1a3d46e377a7248e Mon Sep 17 00:00:00 2001 From: Matt Gadda Date: Mon, 19 May 2025 17:56:02 -0700 Subject: [PATCH 1/4] Add interface addition event in SchemaDiff Update `SchemaDiff.checkImplements` to emit ADDITION events for new interfaces. * Add a loop to iterate over new interfaces and check if they are present in old interfaces. * Emit an ADDITION event if a new interface is not present in the old interfaces. * Retain the existing behavior with respect to interface removals. Add a new test case in `SchemaDiffTest.groovy` to verify that `checkImplements` emits ADDITION events for new interfaces. * Add a test case to cover scenarios where new interfaces are added and old interfaces are removed. --- For more details, open the [Copilot Workspace session](https://copilot-workspace.githubnext.com/mgadda/graphql-java?shareId=XXXX-XXXX-XXXX-XXXX). --- .../java/graphql/schema/diff/SchemaDiff.java | 13 +++++++ .../graphql/schema/diff/SchemaDiffTest.groovy | 37 +++++++++++++++++++ 2 files changed, 50 insertions(+) diff --git a/src/main/java/graphql/schema/diff/SchemaDiff.java b/src/main/java/graphql/schema/diff/SchemaDiff.java index 4676c2d83..627981969 100644 --- a/src/main/java/graphql/schema/diff/SchemaDiff.java +++ b/src/main/java/graphql/schema/diff/SchemaDiff.java @@ -533,6 +533,19 @@ private void checkImplements(DiffCtx ctx, ObjectTypeDefinition old, List o checkInterfaceType(ctx, oldInterface.get(), newInterface.get());
