New submission from STINNER Victor <vstinner at python.org>:
In bpo-26588, I modified the _tracemalloc module to support tracing memory allocations in multiple "domains" for numpy. I modified hashtable.c to support keys larger than void*, and I modified _tracemalloc.c to use a new pointer_t structure which is made of (domain: unsigned int, ptr: void*).
These changes made hashtable.c way more complicated than what it should be. I would like to reuse hashtable.c in more places. I am working on a change to remove the pointer_t type from _tracemalloc.c, and instead use a hash table for traces of domains other than the default domain (0). The new hash table maps a domain to a hash table: traces of a domain.
tracemalloc_traces remains the default hash table for traces of the default domain. Since it's the most common case, it doesn't go through the new hash table.
