Modify the python wrapper to return uint32_t, which prevents incorrect child name-to-index mapping and avoids performing redundant operations on non-existent SBValues. >From c0cb562de3e4c8f4a2b8e3410d4f209a2d473a52 Mon Sep 17 00:00:00 2001 From: Ebuka Ezike <[email protected]> Date: Sun, 26 Oct 2025 13:30:14 +0000 Subject: [PATCH] [lldb] Do not narrow `GetIndexOfChildWithName` return type to int Modify the python wrapper to return uint32_t, which prevents incorrect child name-to-index mapping and avoids performing redundant operations on non-existent SBValues. --- lldb/bindings/python/python-wrapper.swig | 2 +- lldb/include/lldb/Interpreter/ScriptInterpreter.h | 2 +- .../Plugins/ScriptInterpreter/Python/SWIGPythonBridge.h | 5 +++-- .../ScriptInterpreter/Python/ScriptInterpreterPython.cpp | 6 +++--- .../ScriptInterpreter/Python/ScriptInterpreterPythonImpl.h | 2 +- lldb/unittests/ScriptInterpreter/Python/PythonTestSuite.cpp | 3 ++- 6 files changed, 11 insertions(+), 9 deletions(-) diff --git a/lldb/bindings/python/python-wrapper.swig b/lldb/bindings/python/python-wrapper.swig index 64b7dc8381073..e7acba5b95d89 100644 --- a/lldb/bindings/python/python-wrapper.swig +++ b/lldb/bindings/python/python-wrapper.swig @@ -312,7 +312,7 @@ PyObject *lldb_private::python::SWIGBridge::LLDBSwigPython_GetChildAtIndex(PyObj return result.release();
