URL: https://github.com/llvm/llvm-project/commit/d3e0f7e1503b1bca8baa6483d3b5c452a91f60a6 DIFF: https://github.com/llvm/llvm-project/commit/d3e0f7e1503b1bca8baa6483d3b5c452a91f60a6.diff LOG: [lldb/Plugins] Add support of multiple ScriptedThreads in a ScriptedProcess This patch adds support of multiple Scripted Threads in a ScriptedProcess. This is done by fetching the Scripted Threads info dictionary at every ScriptedProcess::DoUpdateThreadList and iterate over each element to create a new ScriptedThread using the object instance, if it was not already available. This patch also adds the ability to pass a pointer of a script interpreter object instance to initialize a ScriptedInterface instead of having to call the script object initializer in the ScriptedInterface constructor. This is used to instantiate the ScriptedThreadInterface from the ScriptedThread constructor, to be able to perform call on that script interpreter object instance. Finally, the patch also updates the scripted process test to check for multiple threads. rdar://84507704 Differential Revision: https://reviews.llvm.org/D117071 Signed-off-by: Med Ismail Bennani <medismail.benn...@gmail.com> Added: lldb/test/API/functionalities/scripted_process/main.cpp Modified: lldb/examples/python/scripted_process/scripted_process.py lldb/include/lldb/Interpreter/ScriptedInterface.h lldb/include/lldb/Interpreter/ScriptedProcessInterface.h lldb/source/Plugins/Process/scripted/ScriptedProcess.cpp lldb/source/Plugins/Process/scripted/ScriptedThread.cpp lldb/source/Plugins/Process/scripted/ScriptedThread.h lldb/source/Plugins/ScriptInterpreter/Python/ScriptedProcessPythonInterface.cpp lldb/source/Plugins/ScriptInterpreter/Python/ScriptedProcessPythonInterface.h lldb/source/Plugins/ScriptInterpreter/Python/ScriptedThreadPythonInterface.cpp lldb/source/Plugins/ScriptInterpreter/Python/ScriptedThreadPythonInterface.h lldb/test/API/functionalities/scripted_process/Makefile lldb/test/API/functionalities/scripted_process/TestScriptedProcess.py lldb/test/API/functionalities/scripted_process/invalid_scripted_process.py lldb/test/API/functionalities/scripted_process/stack_core_scripted_process.py Removed: lldb/test/API/functionalities/scripted_process/main.c ################################################################################ diff --git a/lldb/examples/python/scripted_process/scripted_process.py b/lldb/examples/python/scripted_process/scripted_process.py index ec751b495fdb6..83ec3513cfcd7 100644 --- a/lldb/examples/python/scripted_process/scripted_process.py +++ b/lldb/examples/python/scripted_process/scripted_process.py @@ -70,7 +70,7 @@ def get_thread_with_id(self, tid): tid (int): Thread ID to look for in the scripted process.
