* Fix for SF bug 110688: Instance deallocation neglected to account forTim Peters2000-09-171-12/+28
| | | | | | | | | | that Py_INCREF boosts global _Py_RefTotal when Py_REF_DEBUG is defined but Py_TRACE_REFS isn't. There are, IMO, way too many preprocessor gimmicks in use for refcount debugging (at least 3 distinct true/false symbols, but not all 8 combos are supported by the code, etc etc), and no coherent documentation of this stuff -- 'twas too painful to track this one down.

Includes rudimentary documentation (it could use a cross reference to the section on slice objects, I couldn't figure out how to do that) and a test suite for all Python __hooks__ I could think of, including the new behaviour.

| | | | | | | | | | comments, docstrings or error messages. I fixed two minor things in test_winreg.py ("didn't" -> "Didn't" and "Didnt" -> "Didn't"). There is a minor style issue involved: Guido seems to have preferred English grammar (behaviour, honour) in a couple places. This patch changes that to American, which is the more prominent style in the source. I prefer English myself, so if English is preferred, I'd be happy to supply a patch myself ;)

* Trent Mick <trentm@activestate.com>:Fred Drake2000-06-301-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | The common technique for printing out a pointer has been to cast to a long and use the "%lx" printf modifier. This is incorrect on Win64 where casting to a long truncates the pointer. The "%p" formatter should be used instead. The problem as stated by Tim: > Unfortunately, the C committee refused to define what %p conversion "looks > like" -- they explicitly allowed it to be implementation-defined. Older > versions of Microsoft C even stuck a colon in the middle of the address (in > the days of segment+offset addressing)! The result is that the hex value of a pointer will maybe/maybe not have a 0x prepended to it. Notes on the patch: There are two main classes of changes: - in the various repr() functions that print out pointers - debugging printf's in the various thread_*.h files (these are why the patch is large) Closes SourceForge patch #100505.
* final patches from Neil Schemenauer for garbage collectionJeremy Hylton2000-06-301-4/+13

* This patch addresses two main issues: (1) There exist some non-fatalFred Drake2000-06-291-4/+1
| | | | | | | | | | | | | | | | | | | | 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.
* Vladimir Marangozov:Guido van Rossum2000-06-281-3/+3
| | | | | | Avoid calling the dealloc function, previously triggered with DECREF(inst). This caused a segfault in PyDict_GetItem, called with a NULL dict, whenever inst->in_dict fails under low-memory conditions.
* Trent Mick: change a few casts for Win64 compatibility.Guido van Rossum2000-06-281-1/+1

* part 2 of Neil Schemenauer's GC patches:Jeremy Hylton2000-06-231-6/+6
| | | | | | | | This patch modifies the type structures of objects that participate in GC. The object's tp_basicsize is increased when GC is enabled. GC information is prefixed to the object to maintain binary compatibility. GC objects also define the tp_flag Py_TPFLAGS_GC.

* Round 1 of Neil Schemenauer's GC patches:Jeremy Hylton2000-06-231-1/+87
| | | | | This patch adds the type methods traverse and clear necessary for GC implementation.
* Vladimir Marangozov's long-awaited malloc restructuring.Guido van Rossum2000-05-031-7/+6
| | | | | | | | | | 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.)
* potentially useless optimizationJeremy Hylton2000-04-261-11/+20
| | | | | | | | | | | | | | | | | | | | The previous checkin (2.84) added a PyErr_Format call that made the cost of raising an AttributeError much more expensive. In general this doesn't matter, except that checks for __init__ and __del__ methods, where exceptions are caught and cleared in C, also got much more expensive. The fix is to split instance_getattr1 into two calls: instance_getattr2 checks the instance and the class for the attribute and returns it or returns NULL on error. It does not raise an exception. instance_getattr1 does rexec checks, then calls instance_getattr2. It raises an exception if instance_getattr2 returns NULL. PyInstance_New and instance_dealloc now call instance_getattr2 directly.
* Mark Hammond:Guido van Rossum2000-04-101-1/+4
| | | | | | | | In line with a similar checkin to object.c a while ago, this patch gives a more descriptive error message for an attribute error on a class instance. The message now looks like: AttributeError: 'Descriptor' instance has no attribute 'GetReturnType'

(Note: __name__ really doesn't need to be a special attribute, but that would be more work.)
