gh-89419: gdb: fix printing AttributeError in py-locals when no frame is available - #100611
Merged
Conversation
…e is available ``` Unable to read information on python frame Python Exception <class 'AttributeError'>: 'NoneType' object has no attribute 'co_name' ``` Regression in commit b4903af. While refactoring the code into a while loop, the previous early return when no frame exists went missing. We have just printed a message that we cannot get information about this, so the frame will be None, and we cannot attempt to use it. Discovered on python 3.11, in python 3.12a2 this should error out with `.is_shim()` instead of `co_name`.

This will need manual backporting to 3.11 as cherry-picking doesn't apply cleanly. Prepared at 199e6ec. |
