Subject: [PATCH] [lldb/Interpreter] Implement
ScriptedFrameProvider{,Python}Interface
This patch implements the base and python interface for the
ScriptedFrameProvider class.
This is necessary to call python APIs from the ScriptedFrameProvider
that will come in a follow-up.

+ """
+ The base class for a scripted frame provider.
+
+ A scripted frame provider allows you to provide custom stack frames for a
+ thread, which can be used to augment or replace the standard unwinding
+ mechanism. This is useful for:
+
+ - Providing frames for custom calling conventions or languages
+ - Reconstructing missing frames from crash dumps or core files
+ - Adding diagnostic or synthetic frames for debugging
+ - Visualizing state machines or async execution contexts
+
+ Most of the base class methods are `@abstractmethod` that need to be
+ overwritten by the inheriting class.
+
+ Example usage:
+
+ .. code-block:: python
+
+ # Attach a frame provider to a thread
+ thread = process.GetSelectedThread()
+ error = thread.SetScriptedFrameProvider(
+ "my_module.MyFrameProvider",
+ lldb.SBStructuredData()
+ )
+ """
+
+ @abstractmethod
+ def __init__(self, input_frames, args):
+ """Construct a scripted frame provider.
+
+ Args:
+ input_frames (lldb.SBFrameList): The frame list to use as input.
+ This allows you to access frames by index. The frames are
+ materialized lazily as you access them.
+ args (lldb.SBStructuredData): A Dictionary holding arbitrary
+ key/value pairs used by the scripted frame provider.

+
+ @abstractmethod
+ def get_frame_at_index(self, index):
+ """Get a single stack frame at the given index.
+
+ This method is called lazily when a specific frame is needed in the
+ thread's backtrace (e.g., via the 'bt' command). Each frame is
+ requested individually as needed.
+
+ Args:
+ index (int): The frame index to retrieve (0 for youngest/top frame).
+
+ Returns:
+ Dict or None: A frame dictionary describing the stack frame, or None
+ if no frame exists at this index. The dictionary should contain:
+
+ Required fields:
+ - idx (int): The synthetic frame index (0 for youngest/top frame)
+ - pc (int): The program counter address for the synthetic frame
+
+ Alternatively, you can return:
+ - A ScriptedFrame object for full control over frame behavior
+ - An integer representing an input frame index to reuse
+ - None to indicate no more frames exist
+
+ Example:
+
+ .. code-block:: python
+
+ def get_frame_at_index(self, index):
+ # Return None when there are no more frames
+ if index >= self.total_frames:
+ return None
+
+ # Re-use an input frame by returning its index
+ if self.should_use_input_frame(index):
+ return index # Returns input frame at this index
+
+ # Or create a custom frame dictionary
+ if index == 0:
+ return {
+ "idx": 0,
+ "pc": 0x100001234,
+ }
+
+ return None
+
+ Note:
+ The frames are indexed from 0 (youngest/top) to N (oldest/bottom).
+ This method will be called repeatedly with increasing indices until
+ None is returned.
