gh-99537: Use Py_SETREF() function in C code (#99657) 
Fix potential race condition in code patterns:

* Replace "Py_DECREF(var); var = new;" with "Py_SETREF(var, new);"
* Replace "Py_XDECREF(var); var = new;" with "Py_XSETREF(var, new);"
* Replace "Py_CLEAR(var); var = new;" with "Py_XSETREF(var, new);"

Other changes:

* Replace "old = var; var = new; Py_DECREF(var)"
  with "Py_SETREF(var, new);"
* Replace "old = var; var = new; Py_XDECREF(var)"
  with "Py_XSETREF(var, new);"
* And remove the "old" variable.

gh-98811: use full source location to simplify __future__ imports error checking. This also fixes an incorrect error offset. (GH-98812) 2022-10-31 13:08:03 +00:00
Mark Shannon 22863df7ca
GH-96793: Change `FOR_ITER` to not pop the iterator on exhaustion. (GH-96801) 
Change FOR_ITER to have the same stack effect regardless of whether it branches or not.
Performance is unchanged as FOR_ITER (and specialized forms jump over the cleanup code).

gh-98461: Fix location of RETURN_VALUE in async generator bytecode. compiler_jump_if no longer needs a pointer to the loc. (GH-98494) 2022-10-25 12:26:26 +01:00

gh-97912: Avoid quadratic behavior when adding LOAD_FAST_CHECK (GH-97952) 
* The compiler analyzes the usage of the first 64 local variables all at once using bit masks.

* Local variables beyond the first 64 are only partially analyzed, achieving linear time.
