-------------------- ChangeLog entries follow: --------------------
src/ChangeLog addition:
2010-03-24 Ben Wing <ben@xemacs.org>
* array.h:
* array.h (XD_LISP_DYNARR_DESC):
* dumper.c (pdump_register_sub):
* dumper.c (pdump_store_new_pointer_offsets):
* dumper.c (pdump_reloc_one_mc):

* lrecord.h (IF_NEW_GC):
* lrecord.h (enum memory_description_type):
* lrecord.h (enum data_description_entry_flags):
* lrecord.h (struct opaque_convert_functions):
Rename XD_LISP_OBJECT_BLOCK_PTR to XD_INLINE_LISP_OBJECT_BLOCK_PTR
and document it in lrecord.h.
* data.c:
* data.c (finish_marking_weak_lists):
* data.c (continue_marking_ephemerons):
* data.c (finish_marking_ephemerons):
* elhash.c (MARK_OBJ):
* gc.c:
* gc.c (lispdesc_indirect_count_1):
* gc.c (struct):
* gc.c (kkcc_bt_push):
* gc.c (kkcc_gc_stack_push):
* gc.c (kkcc_gc_stack_push_lisp_object):
* gc.c (kkcc_gc_stack_repush_dirty_object):
* gc.c (KKCC_DO_CHECK_FREE):
* gc.c (mark_object_maybe_checking_free):
* gc.c (mark_struct_contents):
* gc.c (mark_lisp_object_block_contents):
* gc.c (register_for_finalization):
* gc.c (mark_object):
* gc.h:
* lisp.h:
* profile.c:
* profile.c (mark_profiling_info_maphash):
Clean up KKCC code related to DEBUG_XEMACS. Rename
kkcc_backtrace() to kkcc_backtrace_1() and add two params: a
`size' arg to control how many stack elements to print and a
`detailed' arg to control whether Lisp objects are printed using
`debug_print()'. Create front-ends to kkcc_backtrace_1() --
kkcc_detailed_backtrace(), kkcc_short_backtrace(),
kkcc_detailed_backtrace_full(), kkcc_short_backtrace_full(), as
well as shortened versions kbt(), kbts(), kbtf(), kbtsf() -- to
call it with various parameter values. Add an `is_lisp' field to
the stack and backtrace structures and use it to keep track of
whether an object pushed onto the stack is a Lisp object or a
non-Lisp structure; in kkcc_backtrace_1(), don't try to print a
non-Lisp structure as a Lisp object.
* elhash.c:
* extents.c:
* file-coding.c:
* lrecord.h:
* lrecord.h (IF_NEW_GC):
* marker.c:
* marker.c (Fmarker_buffer):
* mule-coding.c:
* number.c:
* rangetab.c:
* specifier.c:
New macros IF_OLD_GC(), IF_NEW_GC() to simplify declaration of
Lisp objects when a finalizer may exist in one but not the other.
Use them appropriately.
* extents.c (finalize_extent_info):
Don't zero out data->soe and data->extents before trying to free,
else we get memory leaks.
* lrecord.h (enum lrecord_type):
Make the first lrecord type have value 1 not 0 so that 0 remains
without implementation and attempts to interpret zeroed memory
as a Lisp object will be more obvious.
* array.c (Dynarr_free):
* device-msw.c (msprinter_delete_device):
* device-tty.c (free_tty_device_struct):
* device-tty.c (tty_delete_device):
* dialog-msw.c (handle_directory_dialog_box):
* dialog-x.c:
* emacs.c (free_argc_argv):
* emodules.c (attempt_module_delete):
* file-coding.c (chain_finalize_coding_stream_1):
* file-coding.c (chain_finalize_coding_stream):
* glyphs-eimage.c:
* glyphs-eimage.c (jpeg_instantiate_unwind):
* glyphs-eimage.c (gif_instantiate_unwind):
* glyphs-eimage.c (png_instantiate_unwind):
* glyphs-eimage.c (tiff_instantiate_unwind):
* imgproc.c:
* imgproc.c (build_EImage_quantable):
* insdel.c (uninit_buffer_text):
* mule-coding.c (iso2022_finalize_detection_state):
* objects-tty.c (tty_finalize_color_instance):
* objects-tty.c (tty_finalize_font_instance):
* objects-tty.c (tty_font_list):
* process.c:
* process.c (finalize_process):
* redisplay.c (add_propagation_runes):
* scrollbar-gtk.c:
* scrollbar-gtk.c (gtk_free_scrollbar_instance):
* scrollbar-gtk.c (gtk_release_scrollbar_instance):
* scrollbar-msw.c:
* scrollbar-msw.c (mswindows_free_scrollbar_instance):
* scrollbar-msw.c (unshow_that_mofo):
* scrollbar-x.c (x_free_scrollbar_instance):
* scrollbar-x.c (x_release_scrollbar_instance):
* select-x.c:
* select-x.c (x_handle_selection_request):
* syntax.c:
* syntax.c (uninit_buffer_syntax_cache):
* text.h (eifree):
If possible, whenever we call xfree() on a field in a structure,
set the field to 0 afterwards. A lot of code is written so that
it checks the value being freed to see if it is non-zero before
freeing it -- doing this and setting the value to 0 afterwards
ensures (a) we won't try to free twice if the cleanup code is
called twice; (b) if the object itself stays around, KKCC won't
crash when attempting to mark the freed field.
* rangetab.c:
Add a finalization method when not NEW_GC to avoid memory leaks.
(#### We still get memory leaks when NEW_GC; need to convert gap
array to Lisp object).
