* Widen modiff counts to avoid wraparoundPaul Eggert2019-01-311-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* forward-line now works with bignumsPaul Eggert2019-01-271-12/+20
| | | | | | | | | | | | * src/cmds.c (Fforward_line): Support bignum arg. (scan_newline): Return void since no caller was using the return value. * src/search.c (find_newline, scan_newline_from_point) (find_newline1): Return the number of newlines counted, not the count shortage, so that the return value always fits in ptrdiff_t even if the original count was a bignum. All callers changed. * test/src/cmds-tests.el (forward-line-with-bignum): New test.

| * Use alignas to fix GCALIGN-related bugsPaul Eggert2017-11-131-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use alignas and unions to specify alignments of objects needing addresses that are at least a multiple of GCALIGNMENT. Using these standard C facilities should be safer than relying on ad hoc and poorly-understood features like GCC’s __attribute__ ((aligned (N))), the root cause for recent porting bugs like Bug#29040. The alignas macro was standardized by C11 and Gnulib supports alignas for pre-C11 platforms. I have tested this on Sun Studio 12 sparc (2007) and GCC 4.4.7 x86-64 (2012) as well as on more recent platforms like GCC 7.2.1 (2017) on Fedora 26 (both x86-64 and x86). * lib-src/make-docfile.c (close_emacs_globals): lispsym is now just an array of struct Lisp_Symbol, since struct Lisp_Symbol is now properly aligned. All uses changed. * src/alloc.c (NEXT_FREE_LISP_STRING): Just use the new u.next member; this is simpler and safer than casting a pointer that might not be aligned properly. (aligned_Lisp_Symbol): Remove. No longer needed, now that struct Lisp_Symbol is aligned properly. All uses replaced with struct Lisp_Symbol. * src/lisp.h (GCALIGNED): Remove, as it does not work as expected: it can cause the natural alignment to be ignored. All uses replaced by unions with a ‘char alignas (GCALIGNMENT)’ member as described below. (struct Lisp_Symbol, struct Lisp_Cons, struct Lisp_String): Change definition from ‘struct TAG { MEMBERS };’ to ‘struct TAG { union { struct { MEMBERS } s; char alignas (GCALIGNMENT) gcaligned; } u; };’. This guarantees ‘struct TAG’ to have an alignment that at least max (GCALIGNMENT, N) where N is its old alignment. All uses like ‘PTR->MEMBER’ changed to ‘PTR->u.s.MEMBER’; these uses were supposed to be mostly private anyway. Verify that the resulting ‘struct TAG’ is properly aligned for Emacs. (union vectorlike_header): New member ‘gcaligned’ to guarantee that this type, and its containing types like ‘struct Lisp_Subr’, ‘struct buffer’ and ‘struct thread_state’, are all properly aligned for Emacs. (struct Lisp_String): New union member ‘next’, for the benefit of NEXT_FREE_LISP_STRING. (union Aligned_Cons, union Aligned_String): Remove. All uses replaced by struct Lisp_Cons and struct Lisp_String, since they are now properly aligned. (USE_STACK_CONS, USE_STACK_STRING): Simplify now that we can assume struct Lisp_Cons and struct Lisp_String are properly aligned.

* 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.

| | | | | | | | | | | | | | | It's important to adjust the match data in between calling before-change-functions and after-change-functions, so that buffer change hooks will always see match-data consistent with buffer content.

Update all callers (except Freplace_match) to pass 0 for the new parameter. * src/search.c (update_search_regs): New function, extracted from Freplace_match.

|/ | | | | | | | | Although \( is needed in docstrings in Elisp code, it is not needed in docstrings in C code, since C function definitiions do not start with a parenthesis.

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.

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.

(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.

* Port better to POSIX hosts lacking _setjmp.Paul Eggert2012-09-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | * configure.ac (HAVE__SETJMP, HAVE_SIGSETJMP): New symbols. (_setjmp, _longjmp): Remove. * src/lisp.h: Include <setjmp.h> here, since we use its symbols here. All instances of '#include <setjmp.h>' removed, if the only reason for the instance was because "lisp.h" was included. (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols. Unless otherwise specified, replace all uses of jmp_buf, _setjmp, and _longjmp with the new symbols. Emacs already uses _setjmp if available, so this change affects only POSIXish hosts that have sigsetjmp but not _setjmp, such as some versions of Solaris and Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.) * src/image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros. (png_load_body) [HAVE_PNG]: (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]: (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]: Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp, since PNG requires jmp_buf. This is the only exception to the general rule that we now use sys_setjmp and sys_longjmp. This exception is OK since this code does not change the signal mask or longjmp out of a signal handler.
