* Add support for weak references to the function and method types.Fred Drake2001-03-231-1/+6
|
* A small change to the C API for weakly-referencable types: Such typesFred Drake2001-03-221-0/+1
| | | | | | | | must now initialize the extra field used by the weak-ref machinery to NULL themselves, to avoid having to require PyObject_INIT() to check if the type supports weak references and do it there. This causes less work to be done for all objects (the type object does not need to be consulted to check for the Py_TPFLAGS_HAVE_WEAKREFS bit).
* The return value from PyObject_ClearWeakRefs() is no longer meaningful,Fred Drake2001-02-261-2/+1

* Fix a leak in instance_coerce(). This was introduced by Neil'sGuido van Rossum2001-01-171-2/+0
| | | | | | | | | earlier coercion changes, not by rich comparisons. When a coercion function returns 1 (meaning it cannot do it), it should not INCREF the arguments. When no __coerce__() method was found, instance_coerce() originally returned 0, pretending it did it. Neil changed the return value to 1, more accurately reflecting that it didn't do anything, but forgot to take out the two INCREF calls.
* Rich comparisons.Guido van Rossum2001-01-171-146/+278
| | | | | | | | | | | | | | | | - Got rid of instance_cmp(); refactored instance_compare(). - Added instance_richcompare() which calls __lt__() etc. Some unrelated stuff mixed in: - Aligned comments in various large struct initializers. - Better test to avoid recursion if __coerce__ returns self as the first argument (this is an unrelated fix by Neil Schemenauer!). - Style nit: don't use Py_DECREF(Py_NotImplemented); use Py_DECREF(result) -- it just looks better. :-)
* Committing PEP 232, function attribute feature, approved by Guido.Barry Warsaw2001-01-151-4/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Closes SF patch #103123. funcobject.h: PyFunctionObject: add the func_dict slot. funcobject.c: PyFunction_New(): Initialize the func_dict slot to NULL. func_getattr(): Rename to func_getattro() and change the signature. It's more efficient to use attro methods and dig the C string out than it is to re-convert a C string to a PyString. Also, add support for getting the __dict__ (a.k.a. func_dict) attribute, and for getting an arbitrary function attribute. func_setattr(): Rename to func_setattro() and change the signature for the same reason. Also add support for setting __dict__ (a.k.a. func_dict) and any arbitrary function attribute. func_dealloc(): Be sure to DECREF the func_dict slot. func_traverse(): Be sure to traverse func_dict too. PyFunction_Type: make the necessary func_?etattro() changes. classobject.c: instancemethod_memberlist: Add __dict__ instancemethod_setattro(): New method to set arbitrary attributes on methods (really the underlying im_func). Raise TypeError when the instance is bound or when you're trying to set one of the reserved im_* attributes. instancemethod_getattr(): Renamed to instancemethod_getattro() since that's what it really is. Also, added support fo getting arbitrary attributes through the im_func. PyMethod_Type: Do the ?etattr{,o} dance.
* Make instances a new style number type. See PEP 208 for details. InstanceNeil Schemenauer2001-01-041-184/+268

* 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'
