From 57bd882343f8e4cca598b6ad47da93476cffb987 Mon Sep 17 00:00:00 2001 From: Med Ismail Bennani Date: Fri, 21 Jul 2023 16:43:24 -0700 Subject: [lldb] Convert script native types to StructuredData counterpart This patch adds the ability to pass native types from the script interpreter to methods that use a {SB,}StructuredData argument. To do so, this patch changes the `ScriptedObject` struture that holds the pointer to the script object as well as the originating script interpreter language. It also exposes that to the SB API via a new class called `SBScriptObject`. This structure allows the debugger to parse the script object and convert it to a StructuredData object. If the type is not compatible with the StructuredData types, we will store its pointer in a `StructuredData::Generic` object. This patch also adds some SWIG typemaps that checks the input argument to ensure it's either an SBStructuredData object, in which case it just passes it throught, or a python object that is NOT another SB type, to provide some guardrails for the user. rdar://111467140 Differential Revision: https://reviews.llvm.org/D155161 Signed-off-by: Med Ismail Bennani --- .../ScriptInterpreter/Python/ScriptInterpreterPython.cpp | 11 +++++++++++ 1 file changed, 11 insertions(+) (limited to 'lldb/source/Plugins/ScriptInterpreter/Python/ScriptInterpreterPython.cpp') diff --git a/lldb/source/Plugins/ScriptInterpreter/Python/ScriptInterpreterPython.cpp b/lldb/source/Plugins/ScriptInterpreter/Python/ScriptInterpreterPython.cpp index 902c7fa..55b7a73 100644 --- a/lldb/source/Plugins/ScriptInterpreter/Python/ScriptInterpreterPython.cpp +++ b/lldb/source/Plugins/ScriptInterpreter/Python/ScriptInterpreterPython.cpp @@ -1519,6 +1519,17 @@ ScriptInterpreterPythonImpl::CreateScriptedProcessInterface() { return std::make_unique(*this); } +StructuredData::ObjectSP +ScriptInterpreterPythonImpl::CreateStructuredDataFromScriptObject( + ScriptObject obj) { + void *ptr = const_cast(obj.GetPointer()); + PythonObject py_obj(PyRefType::Borrowed, static_cast(ptr)); + if (!py_obj.IsValid() || py_obj.IsNone()) + return {}; + Locker py_lock(this, Locker::AcquireLock | Locker::NoSTDIN, Locker::FreeLock); + return py_obj.CreateStructuredObject(); +} + StructuredData::GenericSP ScriptInterpreterPythonImpl::OSPlugin_CreatePluginObject( const char *class_name, lldb::ProcessSP process_sp) { -- cgit v1.1
