* | Prefer functions to macros in buffer.hPaul Eggert2019-09-031-266/+395
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In buffer.h, prefer inline functions to function-like macros when either will do. This helps avoid confusion about how many times an arg is evaluated. On my platform, this patch improves performance of ‘make compile-always’ by 5.7%. Also, prefer enum constants to object-like macros when either will do. * src/buffer.h (BEG, BEG_BYTE, GAP_BYTES_DFL, GAP_BYTES_MIN) (MAX_PER_BUFFER_VARS, NONEXISTENT_MODTIME_NSECS) (UNKNOWN_MODTIME_NSECS, BUFFER_LISP_SIZE, BUFFER_REST_SIZE): Now enum constants, instead of macros. (BUFFER_CEILING_OF, BUFFER_FLOOR_OF, BUF_BEG, BUF_BEG_BYTE) (BUF_BEGV, BUF_BEGV_BYTE, BUF_PT, BUF_PT_BYTE, BUF_ZV) (BUF_ZV_BYTE, BUF_GPT_ADDR, BUF_Z_ADDR, BUF_GAP_END_ADDR) (BUF_COMPUTE_UNCHANGED, SET_PT, TEMP_SET_PT, SET_PT_BOTH) (TEMP_SET_PT_BOTH, BUF_TEMP_SET_PT, SET_BUF_BEGV, SET_BUF_ZV) (SET_BUF_BEGV_BOTH, SET_BUF_ZV_BOTH, SET_BUF_PT_BOTH) (BYTE_POS_ADDR, CHAR_POS_ADDR, CHAR_TO_BYTE, BYTE_TO_CHAR) (PTR_BYTE_POS, FETCH_CHAR, FETCH_CHAR_AS_MULTIBYTE) (BUF_BYTE_ADDRESS, BUF_CHAR_ADDRESS, BUF_PTR_BYTE_POS) (BUF_FETCH_CHAR, BUF_FETCH_CHAR_AS_MULTIBYTE, BUF_FETCH_BYTE) (BUFFER_PVEC_INIT, BUFFER_LIVE_P, BUFFER_HIDDEN_P) (BUFFER_CHECK_INDIRECTION, OVERLAY_POSITION, PER_BUFFER_VALUE_P) (SET_PER_BUFFER_VALUE_P, PER_BUFFER_IDX): Now inline functions instead of macros.
* | Take last_per_buffer_idx privatePaul Eggert2019-09-031-12/+6
|/ | | | | | | | This will simplify future changes. Turn the runtime check into an eassert, since it’s not needed in production. * src/buffer.c (last_per_buffer_idx): Now static. (valid_per_buffer_idx): New function. * src/buffer.h (PER_BUFFER_VALUE_P, SET_PER_BUFFER_VALUE_P): Use it.
* * src/marker.c (buf_bytepos_to_charpos): Re-add the CHAR_HEAD_P assertionStefan Monnier2019-05-071-0/+4
| | | | | | | | | | | | This assertion was removed in 1c349c62305d432abf0fa2b6e3f5d754fe4cab79 because the assumption was invalid during set_intervals_multibyte_1. So we change set_intervals_multibyte_1 to solve the problem in the same way as in the rest of Fset_buffer_multibyte, which actually simplifies the code. * src/buffer.c (advance_to_char_boundary): Not static any more. * src/buffer.h (advance_to_char_boundary): Add prototype. * src/intervals.c (set_intervals_multibyte_1): Use it.
* Allow gap before first non-Lisp pseudovec memberPaul Eggert2019-04-081-8/+6
| | | | | | | | | | | | | Problem reported by Keith David Bershatsky in: https://lists.gnu.org/r/emacs-devel/2019-04/msg00259.html Solution suggested by Stefan Monnier in: https://lists.gnu.org/r/emacs-devel/2019-04/msg00282.html * src/buffer.h (BUFFER_LISP_SIZE): Simplify by using PSEUDOVECSIZE. (BUFFER_REST_SIZE): Simplify by using VECSIZE and BUFFER_LISP_SIZE. * src/lisp.h (PSEUDOVECSIZE): Base it on the last Lisp field, not the first non-Lisp field. All callers changed. Callers without Lisp fields changed to use ALLOCATE_PLAIN_PSEUDOVECTOR. (ALLOCATE_PLAIN_PSEUDOVECTOR): New macro.
* Don't run buffer-related hooks in " *code conversion work*" buffersEli Zaretskii2019-03-301-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | Note: portions of this change were mistakenly pushed as part of an unrelated commit a35a1f6a9. * src/buffer.c (Fget_buffer_create): Set inhibit_buffer_hooks non-zero for temporary buffers created by coding.c. Don't run buffer-list-update-hook for such buffers. (Frename_buffer, Fkill_buffer, record_buffer) (Fbury_buffer_internal): Don't run hooks for buffers whose inhibit_buffer_hooks flag is set. * src/buffer.h (struct buffer): New member inhibit_buffer_hooks. * src/pdumper.c (dump_buffer): Dump the new field. Update the hash value in HASH_buffer_XXX. * src/coding.c (make_conversion_work_buffer): Function deleted; code moved to code_conversion_save. (code_conversion_save): Insert code from make_conversion_work_buffer, but arrange for unwind-protecting the current buffer before switching to the work buffer. This avoids leaving reused_workbuf_in_use set if user presses C-g during encoding/decoding. (Vcode_conversion_workbuf_name): Now external variable. * src/coding.h (Vcode_conversion_reused_workbuf): Declare.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Widen modification counts to at least 64 bits, to make wraparound practically impossible. * doc/lispref/buffers.texi (Buffer Modification): Don’t say the modification-count can wrap around. * src/buffer.c (Frestore_buffer_modified_p, Fbuffer_swap_text) (modify_overlay): * src/insdel.c (insert_1_both, insert_from_string_1) (insert_from_gap, insert_from_buffer_1) (adjust_after_replace, replace_range, replace_range_2) (del_range_2, modify_text): * src/textprop.c (modify_text_properties): Use modiff_incr instead of incrementing directly. (Fbuffer_modified_tick, Fbuffer_chars_modified_tick): Don’t assume modification counts fit into fixnums. * src/buffer.h (struct buffer_text, struct buffer): * src/cmds.c (internal_self_insert): * src/fileio.c (Finsert_file_contents): * src/indent.c (last_known_column_modified): * src/keyboard.c (command_loop_1): * src/marker.c (cached_modiff): * src/syntax.c (find_start_modiff, parse_sexp_propertize) (find_defun_start): * src/window.h (struct window): Use modiff_count for modification counts. * src/editfns.c (Fsubst_char_in_region): Copy instead of incrementing modification counts, since integer overflow checking is not needed here. * src/lisp.h (modiff_count): New type. (modiff_incr, modiff_to_integer): New inline functions. * src/pdumper.c (dump_buffer): Update hash.

* | Use native alignment to access Lisp object dataPaul Eggert2018-06-101-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of using __builtin_assume_aligned (P, GCALIGNMENT) to tell GCC that P has alignment 8, use (T *) P where T is the type of the pointed-to object, to tell GCC that P has native alignment. This is simpler, matches the intent better, and should help simplify future improvements. Some of these changes are to pacify gcc -Wnull-dereference, since GCC is smarter about pointers now that Emacs no longer uses __builtin_assume_aligned; these minor changes should improve code efficiency slightly. On Fedora 28 x86-64 with default optimization this patch shrinks the size of the Emacs text segment by 0.36%. * src/conf_post.h (__has_builtin, __builtin_assume_aligned): Remove; no longer used. * src/dbusbind.c (XD_OBJECT_TO_DBUS_TYPE): Pacify -Wnull-dereference by using XCAR instead of CAR_SAFE and XCDR instead of CDR_SAFE when this is safe. * src/fileio.c (Fexpand_file_name): * src/font.c (clear_font_cache): Pacify -Wnull-dereference by removing unnecessary NILP test. * src/keyboard.c (xevent_start): New function. (read_char, read_key_sequence): Pacify -Wnull-dereference by using xevent_start instead of EVENT_START. * src/lisp.h (lisp_h_XUNTAG): Remove; XUNTAG is always a macro now, since it can no longer be implemented as a function. (XUNTAG): New third argument CTYPE. All uses changed. Cast result to CTYPE * instead of using __builtin_assume_aligned. Simplify by using LISP_WORD_TAG. (LISP_WORD_TAG): New macro. (TAG_PTR): Use it. * src/menu.c (x_popup_menu_1): Pacify -Wnull-dereference by using XCAR instead of Fcar and XCDR instead of Fcdr where this is safe.

(Bug#29627)
* Change vectorlike from struct to unionPaul Eggert2017-11-131-1/+1
| | | | | | | * src/lisp.h (vectorlike_headed): Change from struct to union. All uses changed. Since it has only one member, this does not change semantics. This is designed to simplify future changes needed to fix bugs like Bug#29040. All uses changed.
* Prefer HTTPS to FTP and HTTP in documentationPaul Eggert2017-09-131-1/+1
| | | | | | | | | | | | | Most of this change is to boilerplate commentary such as license URLs. This change was prompted by ftp://ftp.gnu.org's going-away party, planned for November. Change these FTP URLs to https://ftp.gnu.org instead. Make similar changes for URLs to other organizations moving away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and fsf.org when this works, as this will further help defend against man-in-the-middle attacks (for this part I omitted the MS-DOS and MS-Windows sources and the test tarballs to keep the workload down). HTTPS is not fully working to lists.gnu.org so I left those URLs alone for now.

* casing: don’t assume letters are *either* upper- or lower-case (bug#24603)Michal Nazarewicz2017-02-151-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | A compatibility digraph characters, such as Dž, are neither upper- nor lower-case. At the moment however, those are reported as upper-case¹ despite the fact that they change when upper-cased. Stop checking if a character is upper-case before trying to up-case it so that title-case characters are handled correctly. This fixes one of the issues mentioned in bug#24603. ¹ Because they change when converted to lower-case. Notice an asymmetry in that for a character to be considered lower-case it must not be upper-case (plus the usual condition of changing when upper-cased). * src/buffer.h (upcase1): Delete. (upcase): Change to upcase character unconditionally just like downcase does it. This is what upcase1 was. * src/casefiddle.c (casify_object, casify_region): Use upcase instead of upcase1 and don’t check !uppercasep(x) before calling upcase. * src/keyboard.c (read_key_sequence): Don’t check if uppercase(x), just downcase(x) and see if it changed. * test/src/casefiddle-tests.el (casefiddle-tests--characters, casefiddle-tests-casing): Update test cases which are now passing.

* | Reorder lisp.h to declare types before using themPaul Eggert2016-12-251-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This puts basic functions for types to be after the corresponding type definitions. This is a more-common programming style in C, and will make it easier to port Emacs to gcc -fcheck-pointer-bounds, since the functions now have access to the corresponding types' sizes. This patch does not change the code; it just moves declarations and definitions and removes no-longer-needed forward declarations (Bug#25128). * src/buffer.c, src/data.c, src/image.c: Include process.h, for PROCESSP. * src/buffer.h (BUFFERP, CHECK_BUFFER, XBUFFER): * src/process.h (PROCESSP, CHECK_PROCESS, XPROCESS): * src/termhooks.h (TERMINALP, XTERMINAL): * src/window.h (WINDOWP, CHECK_WINDOW, XWINDOW): * src/thread.h (THREADP, CHECK_THREAD, XTHREAD, MUTEXP, CHECK_MUTEX) (XMUTEX, CONDVARP, CHECK_CONDVAR, XCONDVAR): Move here from lisp.h. * src/intervals.h: Include buffer.h, for BUFFERP. Include lisp.h, for Lisp_Object. * src/lisp.h: Reorder declarations and definitions as described above. Move thread includes to be later, so that they can use the reordered definitions. Move some symbols to other headers (noted elsewhere). Remove forward decls that are no longer needed. * src/thread.h: Include systhread.h here, not in lisp.h, since lisp.h itself does not need systhread.h.

This avoids bug#25165, caused by failing to record the modified values of point and mark, because current_buffer was set to NULL. Also, don't bother re-setting the buffer if there was no thread switch, as that just wastes cycles. * src/buffer.c (set_buffer_internal_2): New function, with most of the body of set_buffer_internal_1, but without the test for B being identical to the current buffer. (set_buffer_internal_1): Call set_buffer_internal_2 if B is not identical to the current buffer. * src/buffer.h (set_buffer_internal_2): Add prototype. * test/src/thread-tests.el (thread-sticky-point): New test.

This change is a short-term hack; in the longer run we plan to fix cc-mode’s performance for C files that have ‘(’ at the start of a line in a comment or string.

This patch also makes Q constants (e.g., Qnil) constant addresses from the C point of view. * make-docfile.c: Revamp to generate table of symbols, too. Include <stdbool.h>. (xstrdup): New function. (main): Don't process the same file twice. (SYMBOL): New constant in enum global_type. (struct symbol): Turn 'value' member into a union, either v.value for int or v.svalue for string. All uses changed. (add_global): New arg svalue, which overrides value, so that globals can have a string value. (close_emacs_global): New arg num_symbols; all uses changed. Output lispsym decl. (write_globals): Output symbol globals too. Output more ATTRIBUTE_CONST, now that Qnil etc. are C constants. Output defsym_name table. (scan_c_file): Move most of guts into ... (scan_c_stream): ... new function. Scan for DEFSYMs and record symbols found. Don't read past EOF if file doesn't end in newline. * alloc.c, bidi.c, buffer.c, bytecode.c, callint.c, casefiddle: * casetab.c, category.c, ccl.c, charset.c, chartab.c, cmds.c, coding.c: * composite.c, data.c, dbusbind.c, decompress.c, dired.c, dispnew.c: * doc.c, editfns.c, emacs.c, eval.c, fileio.c, fns.c, font.c, fontset.c: * frame.c, fringe.c, ftfont.c, ftxfont.c, gfilenotify.c, gnutls.c: * image.c, inotify.c, insdel.c, keyboard.c, keymap.c, lread.c: * macfont.m, macros.c, minibuf.c, nsfns.m, nsfont.m, nsimage.m: * nsmenu.m, nsselect.m, nsterm.m, print.c, process.c, profiler.c: * search.c, sound.c, syntax.c, term.c, terminal.c, textprop.c, undo.c: * window.c, xdisp.c, xfaces.c, xfns.c, xftfont.c, xmenu.c, xml.c: * xselect.c, xsettings.c, xterm.c: Remove Q vars that represent symbols (e.g., Qnil, Qt, Qemacs). These names are now defined automatically by make-docfile. * alloc.c (init_symbol): New function. (Fmake_symbol): Use it. (c_symbol_p): New function. (valid_lisp_object_p, purecopy): Use it. * alloc.c (marked_pinned_symbols): Use make_lisp_symbol instead of make_lisp_ptr. (garbage_collect_1): Mark lispsym symbols. (CHECK_ALLOCATED_AND_LIVE_SYMBOL): New macro. (mark_object): Use it. (sweep_symbols): Sweep lispsym symbols. (symbol_uses_obj): New function. (which_symbols): Use it. Work for lispsym symbols, too. (init_alloc_once): Initialize Vpurify_flag here; no need to wait, since Qt's address is already known now. (syms_of_alloc): Add lispsym count to symbols_consed. * buffer.c (init_buffer_once): Compare to Qnil, not to make_number (0), when testing whether storage is all bits zero. * dispextern (struct image_type): * font.c (font_property_table): * frame.c (struct frame_parm_table, frame_parms): * keyboard.c (scroll_bar_parts, struct event_head): * xdisp.c (struct props): Use XSYMBOL_INIT (Qfoo) and struct Lisp_Symbol * rather than &Qfoo and Lisp_Object *, since Qfoo is no longer an object whose address can be taken. All uses changed. * eval.c (run_hook): New function. Most uses of Frun_hooks changed to use it, so that they no longer need to take the address of a Lisp sym. (syms_of_eval): Don't use DEFSYM on Vrun_hooks, as it's a variable. * frame.c (syms_of_frame): Add defsyms for the frame_parms table. * keyboard.c (syms_of_keyboard): Don't DEFSYM Qmenu_bar here. DEFSYM Qdeactivate_mark before the corresponding var. * keymap.c (syms_of_keymap): Use DEFSYM for Qmenu_bar and Qmode_line instead of interning their symbols; this avoids duplicates. (LISP_INITIALLY, TAG_PTR) (DEFINE_LISP_SYMBOL_BEGIN, DEFINE_LISP_SYMBOL_END, XSYMBOL_INIT): New macros. (LISP_INITIALLY_ZERO): Use it. (enum symbol_interned, enum symbol_redirect, struct Lisp_Symbol) (EXFUN, DEFUN_ARGS_MANY, DEFUN_ARGS_UNEVALLED, DEFUN_ARGS_*): Move decls up, to avoid forward uses. Include globals.h earlier, too. (make_lisp_symbol): New function. (XSETSYMBOL): Use it. (DEFSYM): Now just a placeholder for make-docfile. * lread.c (DEFINE_SYMBOLS): Define, for globals.h. (intern_sym): New function, with body taken from old intern_driver. (intern_driver): Use it. Last arg is now Lisp integer, not ptrdiff_t. All uses changed. (define_symbol): New function. (init_obarray): Define the C symbols taken from lispsym. Use plain DEFSYM for Qt and Qnil. * syntax.c (init_syntax_once): No need to worry about Qchar_table_extra_slots.
