Tim Peters 406fe3b1c0 Repaired the debug Windows deaths in test_descr, by allocating enough
pad memory to properly align the __dict__ pointer in all cases.

gcmodule.c/objimpl.h, _PyObject_GC_Malloc:
+ Added a "padding" argument so that this flavor of malloc can allocate
  enough bytes for alignment padding (it can't know this is needed, but
  its callers do).

typeobject.c, PyType_GenericAlloc:
+ Allocated enough bytes to align the __dict__ pointer.
+ Sped and simplified the round-up-to-PTRSIZE logic.
+ Added blank lines so I could parse the if/else blocks <0.7 wink>.

Tim Peters 8c18f25850 _PyObject_GC_Malloc(): split a complicated line in two. As is, there was
no way to talk the debugger into showing me how many bytes were being
allocated.

Neil Schemenauer 43411b5683 Make more things internal to this file. Remove
visit_finalizer_reachable since it's the same as visit_reachable.
Rename visit_reachable to visit_move.  Objects can now have the GC type
flag set, reachable by tp_traverse and not be in a GC linked list.  This
should make the collector more robust and easier to use by extension
module writers.  Add memory management functions for container objects
(new, del, resize).

Neil Schemenauer 17e7be60b4 Remove "referents" structure (it's not needed). Check return value
of PyList_Append.

Neil Schemenauer c7c8d8e32d Add get_objects function. This is a low level function (like
get_referents, and is not yet documented in the library manual).
Suggestions for a better name welcome.

Neil Schemenauer 48c7034454 Add get_referents function. Closes SF patch #402925. 2001-08-09 15:38:31 +00:00

Neil Schemenauer 97d723bd62 - do not start collection during processing of an exception 2000-10-04 16:25:07 +00:00
Neil Schemenauer 7760cff294 Fix some long/"l" int/"i" mismatches. Fixes bug #113779. 2000-09-22 22:35:36 +00:00
Neil Schemenauer 544de1effb - Add DEBUG_SAVEALL option. When enabled all garbage objects found by the
collector will be saved in gc.garbage.  This is useful for debugging a
  program that creates reference cycles.

- Fix else statements in gcmodule.c to conform to Python coding standards.

Jeremy Hylton 3263dc2b15 compromise value for threshold0: not too high, not too low 2000-09-05 15:44:50 +00:00
Jeremy Hylton 045946d4ee set the default threshold much higher
we don't need to run gc frequently
2000-09-01 04:01:55 +00:00
Jeremy Hylton b709df3810 refactor __del__ exception handler into PyErr_WriteUnraisable
add sanity check to gc: if an exception occurs during GC, call
PyErr_WriteUnraisable and then call Py_FatalEror.

Jeremy Hylton 0625777b53 apply patch #101362 by Vladimir Marangozov

Vladimir Marangozov f9d20c3786 Neil Schemenauer: GC enable(), disable(), isenabled() interface.
Small stylistic changes by VM:
- is_enabled() -> isenabled()
- static ... Py_<func> -> static ... gc_<func>

Barry Warsaw 35e459c3eb debug_instance(): Use the same %p format directive as with
debug_cycle(), and don't cast the pointer to a long.  Neither needs
the literal `0x' prefix as %p automatically inserts this (on Linux at
least).

Fred Drake cc1be2401e Always use the :funcname part of the format specifier for PyArg_ParseTuple()
so we get better error messages.

Fred Drake b35de5b78a Neil Schemenauer <nascheme@enme.ucalgary.ca>:
Change a cast, intialize a local, and make some sprintf() format strings
type-appropriate (add the "l" to "%d").

Closes SourceForge patch #100737.
