Fred Drake 13634cf7a4 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.

Guido van Rossum b18618dab7 Vladimir Marangozov's long-awaited malloc restructuring.
For more comments, read the patches@python.org archives.
For documentation read the comments in mymalloc.h and objimpl.h.

(This is not exactly what Vladimir posted to the patches list; I've
made a few changes, and Vladimir sent me a fix in private email for a
problem that only occurs in debug mode.  I'm also holding back on his
change to main.c, which seems unnecessary to me.)

Guido van Rossum 43713e5a28 Massive patch by Skip Montanaro to add ":name" to as many
PyArg_ParseTuple() format string arguments as possible.

Guido van Rossum bffd683f73 The rest of the changes by Trent Mick and Dale Nagata for warning-free
compilation on NT Alpha.  Mostly added casts etc.

Guido van Rossum 3bbef60990 Ai! complex_nonzero() has && which should be ||, else decidedly
non-zero things like 5j and complex(1,0) are considered to be
zero/false.  Tim Peters.

Guido van Rossum 8530ef625a Add check to conjugate() that there are no excess arguments. 1998-05-07 16:29:10 +00:00
Guido van Rossum 967839473a Got rid of c_error in favor of errno (and EDOM/ERANGE).
Assume that errno usage is thread-safe -- most vendors do this by
making in a macro that refers to a per-thread storage area.
