gh-140009: Optimize dict object by replacing PyTuple_Pack with PyTuple_FromArray
Summary
This PR replaces
PyTuple_PackwithPyTuple_FromArrayinObjects/dictobject.cfor creating small tuples (size 2).PyTuple_FromArrayis more efficient thanPyTuple_Packbecause it avoids the overhead of variadic arguments (va_args) processing by taking a pointer to a pre-allocated array ofPyObject*.Changes
PyTuple_Pack(2, Py_None, Py_None)withPyTuple_FromArrayusing a stack-allocated array.PyTuple_Pack(2, key, val2)withPyTuple_FromArray.Performance Impact
This is part of a general effort to optimize small tuple creation across the codebase. Replacing
PyTuple_PackwithPyTuple_FromArrayfor small, fixed-size tuples reduces call overhead.
