This is mainly applicable to external C libraries. The interface to
them may not be thread-safe; anything that uses the Python API to
create/manage Python objects will require use of the GI
Hi
Ok, if I understand between Py_BEGIN_ALLOW_THREADS and Py_END_ALLOW_THREADS
is not possible use a C/Python api functions ?
Sorry, but when thread enter another time with Py_END_ALLOW_THREADS this
thread enter to competition to lock GIL ?

Hi,
The C-API uses references counts as well, so it is not threadsafe.

But Python C-API[1] it's the main base for extent python with C/c++, and
this is not not threadsafe.? I dont understand

I think it is because the Python re library uses the Python C-API
which is not threadsafe.

Hi all
I understand that the C implementation of Python use a global interpreter
lock to avoid problems, so doing CPU bound tasks in multiple threads
will not result in better performance on multi-CPU systems.
However, I assumed that calls to (thread safe) C Library functions
release the global i
