Subject: [PATCH] Fix test_none_collisions on 32-bit systems
|
||||
|
||||
There are two issues at play here:
|
||||
|
||||
1. Python version of `map_hash` unnecessarily performs hash truncation
|
||||
even if the hash is already 32-bit wide, which potentially converts
|
||||
it from signed int to unsigned long.
|
||||
|
||||
2. The `test_none_collisions` test generates a collision node with
|
||||
hash greater than 2^32.
|
||||
|
||||
Both of these are problematic on 32-bit systems, where `sizeof(Py_hash_t)`
|
||||
is 4, and so anything that doesn't fit into `Py_hash_t` gets bit-mangled,
|
||||
breaking the `hash(x) != x` invariance that the test relies upon.
|
||||
|
||||
Fixes: #53
|
||||
Fixes: #50
