* SF bug 665835: filter() treatment of str and tuple inconsistentRaymond Hettinger2003-04-242-0/+4
| | | | | | | | As a side issue on this bug, it was noted that list and tuple iterators used macros to directly access containers and would not recognize __getitem__ overrides. If the method is overridden, the patch returns a generic sequence iterator which calls the __getitem__ method; otherwise, it returns a high custom iterator with direct access to container elements.

* - bool() called without arguments now returns False rather thanGuido van Rossum2003-04-191-2/+2
| | | | | | | raising an exception. This is consistent with calling the constructors for the other builtin types -- called without argument they all return the false value of that type. (SF patch #724135) Thanks to Alex Martelli.
* _Py_PrintReferenceAddresses(): also print the type name. In real useTim Peters2003-04-181-1/+2
| | | | | | | | | I'm finding some pretty baffling output, like reprs consisting entirely of three left parens. At least this will let us know what type the object is (it's not str -- there's no quote character in the repr). New tool combinerefs.py, to combine the two output blocks produced via PYTHONDUMPREFS.
* _Py_PrintReferences(): Changed to print object address at start of eachTim Peters2003-04-171-1/+16
| | | | | | | | | | | | | | | new line. New pvt API function _Py_PrintReferenceAddresses(): Prints only the addresses and refcnts of the live objects. This is always safe to call, because it has no dependence on Python's C API. Py_Finalize(): If envar PYTHONDUMPREFS is set, call (the new) _Py_PrintReferenceAddresses() right before dumping final pymalloc stats. We can't print the reprs of the objects here because too much of the interpreter has been shut down. You need to correlate the addresses displayed here with the object reprs printed by the earlier PYTHONDUMPREFS call to _Py_PrintReferences().
* SF # 595026: support for masks in getargs.c.Thomas Heller2003-04-172-0/+146
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | New functions: unsigned long PyInt_AsUnsignedLongMask(PyObject *); unsigned PY_LONG_LONG) PyInt_AsUnsignedLongLongMask(PyObject *); unsigned long PyLong_AsUnsignedLongMask(PyObject *); unsigned PY_LONG_LONG) PyLong_AsUnsignedLongLongMask(PyObject *); New and changed format codes: b unsigned char 0..UCHAR_MAX B unsigned char none ** h unsigned short 0..USHRT_MAX H unsigned short none ** i int INT_MIN..INT_MAX I * unsigned int 0..UINT_MAX l long LONG_MIN..LONG_MAX k * unsigned long none L long long LLONG_MIN..LLONG_MAX K * unsigned long long none Notes: * New format codes. ** Changed from previous "range-and-a-half" to "none"; the range-and-a-half checking wasn't particularly useful. New test test_getargs2.py, to verify all this.

* - pythunrun.c, Py_Finalize(): move the call to _Py_PrintReferences()Guido van Rossum2003-04-151-1/+1
| | | | | | | | | | | | | | | | | | | even farther down, to just before the call to _PyObject_DebugMallocStats(). This required the following changes: - pystate.c, PyThreadState_GetDict(): changed not to raise an exception or issue a fatal error when no current thread state is available, but simply return NULL without raising an exception (ever). - object.c, Py_ReprEnter(): when PyThreadState_GetDict() returns NULL, don't raise an exception but return 0. This means that when printing a container that's recursive, printing will go on and on and on. But that shouldn't happen in the case we care about (see first bullet). - Updated Misc/NEWS and Doc/api/init.tex to reflect changes to PyThreadState_GetDict() definition.

* Make staticmethods and classmethods participate in GC.Jeremy Hylton2003-04-081-8/+45
| | | | | | | | | | If a class was defined inside a function, used a static or class method, and used super() inside the method body, it would be caught in an uncollectable cycle. (Simplified version: The static/class method object would point to a function object with a closure that referred to the class.) Bugfix candidate.

* Improved new Py_TRACE_REFS gimmicks.Tim Peters2003-03-232-18/+37
| | | | | | | | | | | Arranged that all the objects exposed by __builtin__ appear in the list of all objects. I basically peed away two days tracking down a mystery leak in sys.gettotalrefcount() in a ZODB app (== tons of code), because the object leaking the references didn't appear in the sys.getobjects(0) list. The object happened to be False. Now False is in the list, along with other popular & previously missing leak candidates (like None). Alas, we still don't have a choke point covering *all* Python objects, so the list of all objects may still be incomplete.
* slot_sq_contains(): This leaked a reference to the result of callingTim Peters2003-03-231-11/+12
| | | | | | __contains__(). Bugfix candidate.
* Refactored some of the Py_TRACE_REFS code. New private API functionTim Peters2003-03-232-10/+26
| | | | | | | _Py_AddToAllObjects() that simply inserts an object at the front of the doubly-linked list of all objects. Changed PyType_Ready() (the closest thing we've got to a choke point for type objects) to call that.
* Oops! Used a wrong preprocessor symbol.Tim Peters2003-03-231-1/+1

* When Py_TRACE_REFS is defined, a list of all live objects is maintained inTim Peters2003-03-231-2/+15
| | | | | | | | | | | a doubly-linked list, exposed by sys.getobjects(). Unfortunately, it's not really all live objects, and it seems my fate to bump into programs where sys.gettotalrefcount() keeps going up but where the reference leaks aren't accounted for by anything in the list of all objects. This patch helps a little: if COUNT_ALLOCS is also defined, from now on type objects will also appear in this list, provided at least one object of a type has been allocated.

* - The extended type structure used for heap types (new-styleGuido van Rossum2003-03-071-49/+34
| | | | | classes defined by Python code using a class statement) is now exported from object.h as PyHeapTypeObject. (SF patch #696193.)

* Fix from Greg Chapman from SF bug #695651: a complex subclassGuido van Rossum2003-03-021-2/+3
| | | | | | | | | | | | | | constructor, when passed a single complex argument, returns the argument unchanged. This should be done only for the complex base class; a complex subclass should of course cast the value to the subclass in this case. The fix also revealed a segfault in complex_getnewargs(): the argument for the Py_BuildValue() format code "D" is the *address* of a Py_complex struct, not the value. (This corroborated by the API documentation.) I expect this needs to be backported to 2.2.3.
* Removed duplicate test from inner loop.Raymond Hettinger2003-03-011-6/+1

* Fix SF bug #689659, 64-bit int and long hash keys incompatibleNeal Norwitz2003-02-231-2/+4

* Implementing the salient parts of __reduce_ex__ in C.Guido van Rossum2003-02-211-6/+229
| | | | | | | This still falls back to helpers in copy_reg for: - pickle protocols < 2 - calculating the list of slot names (done only once per class) - the __newobj__ function (which is used as a token but never called)

| | | | | | | | the PyInt_AsLong function, and this returns a long, the value is first retrieved with PyLong_AsLong, but afterwards overwritten by a call to PyInt_AS_LONG. Fixes SF #690253.
* PyObject_Generic{Get,Set}Attr:Guido van Rossum2003-02-191-2/+4
| | | | | | | | | | Don't access tp_descr_{get,set} of a descriptor without checking the flag bits of the descriptor's type. While we know that the main type (the type of the object whose attribute is being accessed) has all the right flag bits (or else PyObject_Generic{Get,Set}Attr wouldn't be called), we don't know that for its class attributes! Will backport to 2.2.
