* 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.
* Replace QUIT with maybe_quitPaul Eggert2017-01-251-1/+1
| | | | | | | | There’s no longer need to have QUIT stand for a slug of C statements. Use the more-obvious function-call syntax instead. Also, use true and false when setting immediate_quit. These changes should not affect the generated machine code. * src/lisp.h (QUIT): Remove. All uses replaced by maybe_quit.

* | Rename C names to match Lisp symbols betterPaul Eggert2016-03-271-3/+3
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This was inspired by commit e65c3079c65595d95749348366af9811fafff062, which fixed a bug where the C name for a symbol disagreed with the symbol name itself. Fix other instances of disagreements that I found. Although this doesn’t fix a bug, it should make code easier to follow. The remaining disagreements are idiosyncratic: Qminus, Qplus, Qsans__serif, Qbackquote, Qcomma, Qcomma_at, Qcomma_dot.

* Rework C source files to avoid ^(Paul Eggert2016-03-101-2/+2
| | | | | | | | Work around Bug#22884 by rewording comments and strings to avoid ‘(’ at the start of a line unless it starts a function. 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.

* Give up on -Wsuggest-attribute=constPaul Eggert2015-01-151-2/+1
| | | | | | | | | | | | | | | | The attribute doesn't help performance significantly, and the warning seems to be more trouble than it's worth. See the thread at: http://lists.gnu.org/archive/html/emacs-devel/2015-01/msg00361.html * configure.ac (WERROR_CFLAGS): Don't use -Wsuggest-attribute=const. * lib-src/make-docfile.c (write_globals): Remove special hack for Fnext_read_file_uses_dialog_p. * src/decompress.c (Fzlib_available_p): * src/gnutls.c (Fgnutls_available_p): * src/gtkutil.h (xg_uses_old_file_dialog): * src/xdisp.c (Ftool_bar_height): * src/xmenu.c (popup_activated): No longer const, since it's not const on at lest some configurations, and we shouldn't lie to the compiler.

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.

| | | | | | | | | | | | | | * decompress.c, gnutls.c, image.c, xml.c: If WINDOWSNT, use '#define FOO fn_FOO' to wrap dll functions, rather than the inverse when not WINDOWSNT.

Decompress into the gap instead of into an auto buffer, as this should avoid copying. Return nil if 'inflate' returns Z_NEED_DICT, as we have no dictionary. Do not set immediate_quit; we shouldn't trust zlib code that much.
