[issue14815] random_seed uses only 32-bits of hash on Win64

2012-05-16 Thread Raymond Hettinger 

Raymond Hettinger  added the comment:

This is a reasonable change.  The benefits of using all 64-bits outweigh the 
small downside of losing the reproducibility of previously generated sequences 
that relied on the object hash.

[issue14815] random_seed uses only 32-bits of hash on Win64

2012-05-15 Thread Martin v . Löwis 

New submission from Martin v. Löwis :

random_seed has this code:

  long hash = PyObject_Hash(arg);

On Win64, Py_hash_t is a 64-bit type, yet long is a 32-bit type, so this 
truncates. I think the computation should be done in Py_ssize_t.
