@mib There's a reason I didn't do it this way when I tried to fix this locally.
The python stub function we generate would look something like this with your
patch.
```lang=python
def lldb_autogen_python_wp_callback_func__0 (frame, wp, internal_dict):
global_dict = globals()
new_keys = internal_dict.keys()
old_keys = global_dict.keys()
global_dict.update (internal_dict)
if True:
return call_user_function(frame, wp, internal_dict)
for key in new_keys:
internal_dict[key] = global_dict[key]
if key not in old_keys:
del global_dict[key]
```
with your early return the logic for updating `internal_dict` and `global_dict`
will **not run**. I'm not entirely sure what the purpose of this is but if its
important then we need to implement this patch another way.
Here's another way we could do it. You could take the patch I originally wrote
but change `ScriptInterpreterPythonImpl::GenerateFunction(...)` to take an
additional parameter `bool ReturnValue` that is false by default. This
parameter when `true` would do the work my patch did to make sure we use the
return value from the last user statement evaluated. For the watchpoint
evaluation we can pass a `true` value. For the other cases `ReturnValue` will
be false so there will be no behavior change there.

+ self.expect("thread backtrace", STOPPED_DUE_TO_BREAKPOINT,
+ substrs=['stop reason = breakpoint'])
----------------
This `self.expect()` fails when the bug hasn't been fixed, correct?
