* SF patch #729395: Dictionary tuningRaymond Hettinger2003-05-071-2/+2
| | | | | Adjust resize argument for dict.update() and dict.copy(). Extends the previous change to dict.__setitem__().

* SF patch #729395: Dictionary tuningRaymond Hettinger2003-05-051-10/+16
| | | | | | | | | | * Increase dictionary growth rate resulting in more sparse dictionaries, fewer lookup collisions, increased memory use, and better cache performance. For dicts with over 50k entries, keep the current growth rate in case an application is suffering from tight memory constraints. * Set the most common case (no resize) to fall-through the test.

* SF patch 730594: assert from longobject.c, line 1215.Tim Peters2003-05-051-4/+4
| | | | | | | | Some version of gcc in the "RTEMS port running on the Coldfire (m5200) processor" generates bad code for a loop in long_from_binary_base(), comparing the wrong half of an int to a short. The patch changes the decl of the short temp to be an int temp instead. This "simplifies" the code enough that gcc no longer blows it.

* 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.

* 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.

* 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.
