This roughly follows what was done for dictobject to make a lock-free lookup operation. With this change, the set contains operation scales much better when used from multiple-threads. The frozenset contains performance seems unchanged (as already lock-free). Summary of changes: * refactor set_lookkey() into set_do_lookup() which now takes a function pointer that does the entry comparison. This is similar to dictobject and do_lookup(). In an optimized build, the comparison function is inlined and there should be no performance cost to this. * change set_do_lookup() to return a status separately from the entry value * add set_compare_frozenset() and use if the object is a frozenset. For the free-threaded build, this avoids some overhead (locking, atomic operations, incref/decref on key) * use FT_ATOMIC_* macros as needed for atomic loads and stores * use a deferred free on the set table array, if shared (only on free-threaded build, normal build always does an immediate free) * for free-threaded build, use explicit for loop to zero the table, rather than memcpy() * when mutating the set, assign so->table to NULL while the change is a happening. Assign the real table array after the change is done. |
