Introduce a unified 16-bit backoff counter type (``_Py_BackoffCounter``),
|
|
shared between the Tier 1 adaptive specializer and the Tier 2 optimizer. The
|
|
API used for adaptive specialization counters is changed but the behavior is
|
|
(supposed to be) identical.
|
|
|
|
The behavior of the Tier 2 counters is changed:
|
|
|
|
* There are no longer dynamic thresholds (we never varied these).
|
|
* All counters now use the same exponential backoff.
|
|
* The counter for ``JUMP_BACKWARD`` starts counting down from 16.
|
|
* The ``temperature`` in side exits starts counting down from 64.

Implement an incremental cyclic garbage collector. By collecting the old
|
|
generation in increments, there is no need for a full heap scan. This can
|
|
hugely reduce maximum pause time for programs with large heaps.
|
|
|
|
Reduce the number of generations from three to two. The old generation is
|
|
split into two spaces, "visited" and "pending".
|
|
|
|
Collection happens in two steps:: * An increment is formed from the young
|
|
generation and a small part of the pending space. * This increment is
|
|
scanned and the survivors moved to the end of the visited space.
|
|
|
|
When the collecting space becomes empty, the two spaces are swapped.

In the limited C API version 3.13, getting ``Py_None``, ``Py_False``,
|
|
``Py_True``, ``Py_Ellipsis`` and ``Py_NotImplemented`` singletons is now

implemented as function calls at the stable ABI level to hide implementation
|
|
details. Getting these constants still return borrowed references. Patch by
