From 13634cf7a407202777285172a57cfcddb20a2047 Mon Sep 17 00:00:00 2001 From: Fred Drake Date: Thu, 29 Jun 2000 19:17:04 +0000 Subject: This patch addresses two main issues: (1) There exist some non-fatal errors in some of the hash algorithms. For exmaple, in float_hash and complex_hash a certain part of the value is not included in the hash calculation. See Tim's, Guido's, and my discussion of this on python-dev in May under the title "fix float_hash and complex_hash for 64-bit *nix" (2) The hash algorithms that use pointers (e.g. func_hash, code_hash) are universally not correct on Win64 (they assume that sizeof(long) == sizeof(void*)) As well, this patch significantly cleans up the hash code. It adds the two function _Py_HashDouble and _PyHash_VoidPtr that the various hashing routine are changed to use. These help maintain the hash function invariant: (a==b) => (hash(a)==hash(b))) I have added Lib/test/test_hash.py and Lib/test/output/test_hash to test this for some cases. --- PC/_winreg.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'PC') diff --git a/PC/_winreg.c b/PC/_winreg.c index f92476eb62..45399590e6 100644 --- a/PC/_winreg.c +++ b/PC/_winreg.c @@ -423,7 +423,7 @@ PyHKEY_hashFunc(PyObject *ob) /* Just use the address.
