Added the ability for OS plug-ins to lazily populate the thread this. The python OS plug-in classes can now implement the following method:
class OperatingSystemPlugin:
def create_thread(self, tid, context):
# Return a dictionary for a new thread to create it on demand
This will add a new thread to the thread list if it doesn't already exist. The example code in lldb/examples/python/operating_system.py has been updated to show how this call us used.
Cleaned up the code in PythonDataObjects.cpp/h:
- renamed all classes that started with PythonData* to be Python*.
- renamed PythonArray to PythonList. Cleaned up the code to use inheritance where
- Centralized the code that does ref counting in the PythonObject class to a single function.
- Made the "bool PythonObject::Reset(PyObject *)" function be virtual so each subclass can correctly check to ensure a PyObject is of the right type before adopting the object.
- Cleaned up all APIs and added new constructors for the Python* classes to they can all construct form:
- PyObject *
- const PythonObject &
- const lldb::ScriptInterpreterObjectSP &
Cleaned up code in ScriptInterpreterPython:
- Made calling python functions safer by templatizing the production of value formats. Python specifies the value formats based on built in C types (long, long long, etc), and code often uses typedefs for uint32_t, uint64_t, etc when passing arguments down to python. We will now always produce correct value formats as the templatized code will "do the right thing" all the time.
- Fixed issues with the ScriptInterpreterPython::Locker where entering the session and leaving the session had a bunch of issues that could cause the "lldb" module globals lldb.debugger, lldb.target, lldb.process, lldb.thread, and lldb.frame to not be initialized.
