major dynarr fixes -------------------- ChangeLog entries follow: -------------------- src/ChangeLog addition: 2010-02-20 Ben Wing <ben@xemacs.org> * device-x.c (Fx_get_resource): * dynarr.c: * dynarr.c (Dynarr_realloc): * dynarr.c (Dynarr_newf): * dynarr.c (Dynarr_lisp_realloc): * dynarr.c (Dynarr_lisp_newf): * dynarr.c (Dynarr_resize): * dynarr.c (Dynarr_insert_many): * dynarr.c (Dynarr_delete_many): * dynarr.c (Dynarr_memory_usage): * dynarr.c (stack_like_free): * file-coding.c (coding_reader): * file-coding.c (gzip_convert): * gutter.c (output_gutter): * lisp.h: * lisp.h (Dynarr_declare): * lisp.h (DYNARR_SET_LISP_IMP): * lisp.h (CHECK_NATNUM): * profile.c (create_timing_profile_table): * redisplay-output.c (sync_rune_structs): * redisplay-output.c (sync_display_line_structs): * redisplay-output.c (redisplay_output_window): * redisplay.c: * redisplay.c (get_display_block_from_line): * redisplay.c (add_ichar_rune_1): * redisplay.c (ensure_modeline_generated): * redisplay.c (generate_displayable_area): * redisplay.c (regenerate_window): * redisplay.c (update_line_start_cache): * signal.c: * signal.c (check_quit): Lots of rewriting of dynarr code. (1) Lots of documentation added. Also fix places that referenced a now-bogus internals node concerning redisplay critical sections. (2) Rename: Dynarr_add_lisp_string -> Dynarr_add_ext_lisp_string Dynarr_set_length -> Dynarr_set_lengthr ("restricted") Dynarr_increment -> Dynarr_incrementr Dynarr_resize_if -> Dynarr_resize_to_add (3) New functions: Dynarr_elsize = dy->elsize_ Dynarr_set_length(): Set length, resizing as necessary Dynarr_set_length_and_zero(): Set length, resizing as necessary, zeroing out new elements Dynarr_increase_length(), Dynarr_increase_length_and_zero(): Optimization of Dynarr_set_length(), Dynarr_set_length_and_zero() when size is known to increase Dynarr_resize_to_fit(): Resize as necessary to fit a given length. Dynarr_set(): Set element at a given position, increasing length as necessary and setting any newly created positions to 0 (4) Use Elemcount, Bytecount. (5) Rewrite many macros as inline functions.
