| | | | | | | | | | (GH-103083) * The majority of the monitoring code is in instrumentation.c * The new instrumentation bytecodes are in bytecodes.c * legacy_tracing.c adapts the new API to the old sys.setrace and sys.setprofile APIs

* GH-101291: Rearrange the size bits in PyLongObject (GH-102464)Mark Shannon2023-03-221-4/+4
| | | | | | | | | | * Eliminate all remaining uses of Py_SIZE and Py_SET_SIZE on PyLongObject, adding asserts. * Change layout of size/sign bits in longobject to support future addition of immortal ints and tagged medium ints. * Add functions to hide some internals of long object, and for setting sign and digit count. * Replace uses of IS_MEDIUM_VALUE macro with _PyLong_IsCompact().
