cleanup of code related to xfree(), better KKCC backtrace capabilities, document XD_INLINE_LISP_OBJECT_BLOCK_PTR, fix some memory leaks, other code cleanup -------------------- 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): * elhash.c: * gc.c (lispdesc_one_description_line_size): * gc.c (kkcc_marking): * lrecord.h: * 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).

;;; #### bleck!!! Use key-translation-map!

;;; #### Counter-bleck!! We shouldn't override a user binding for F13.
;;; So we use function-key-map for now.
;;; When we've implemented a fallback-style equivalent of
;;; keyboard-translate-table, we'll use that instead. (martin)

;; For no obvious reason, shift-F1 is called F13, although Meta-F1 and
;; Control-F1 have normal names.
