Hello!
There is Advanced Debugger Support <https://docs.python.org/dev/c-api/init.html#advanced-debugger-support> API in CPython. I see that in CPython source code objects on which it operates are operated on while HEAD_LOCK() is acquired (1 <https://github.com/python/cpython/blob/71a3522ef85df06a3acc718107360e37e4116a15/Python/pystate.c#L285>, 2 <https://github.com/python/cpython/blob/71a3522ef85df06a3acc718107360e37e4116a15/Python/pystate.c#L341>, 3 <https://github.com/python/cpython/blob/71a3522ef85df06a3acc718107360e37e4116a15/Python/pystate.c#L384>, 4 <https://github.com/python/cpython/blob/71a3522ef85df06a3acc718107360e37e4116a15/Python/pystate.c#L1146>). But HEAD_LOCK() is not part of public C-API. So I wonder - is Advanced Debugger Support API really complete because it seems like it can't be used withotu HEAD_LOCK()/HEAD_UNLOCK().
Could someone please enlighten?
