* lisp/emacs-lisp/syntax.el (syntax-ppss): Move the description of
the return value from...
* src/syntax.c (Fparse_partial_sexp): ... here because
`syntax-ppss' is what's called over the place, and jumping through
an indirection to get to the value description is inconvenient.
The main new thing here is that C code can now say
‘list (a, b, c, d, e, f)’ instead of
‘listn (CONSTYPE_HEAP, 6, a, b, c, d, e, f)’,
thus relieving callers of the responsibility of counting
arguments (plus, the code feels more like Lisp). The old
list1 ... list5 functions remain, as they’re probably a bit
faster for small lists.
* src/alloc.c (cons_listn, pure_listn): New functions.
(listn): Omit enum argument.
All callers changed to use either new ‘list’ or ‘pure_list’ macros.
* src/charset.c (Fdefine_charset_internal):
* src/coding.c (detect_coding_system)
(Fset_terminal_coding_system_internal):
* src/frame.c (frame_size_history_add, adjust_frame_size):

* src/kqueue.c (kqueue_generate_event):
* src/nsterm.m (performDragOperation:):
* src/pdumper.c (Fpdumper_stats):
* src/w32.c (init_environment):
Prefer list1, list2, etc. to open-coding them.
* src/font.c (font_list_entities):
Parenthesize to avoid expanding new ‘list’ macro.
* src/gtkutil.c (GETSETUP): Rename from MAKE_FLOAT_PAGE_SETUP
to get lines to fit. Move outside the ‘list’ call, since it’s
now a macro.
* src/keymap.c (Fmake_keymap): Simplify.
* src/lisp.h (list, pure_list): New macros.
(list1i): New function.
Also fix some anomalies in the handling of byte positions in regexp-emacs.c
This fixes bug #34525.
* src/intervals.c (SET_PARENT_POSITION): New macro.
(update_interval): When moving to an interval's parent, set that parent's
->position field, to maintain the consistency of the tree.
* src/intervals.h (struct interval): Amend the comment describing when
->position is valid.
* src/pdumper.c: Update the hash associated with struct interval.
* src/regex-emacs.c: (re_match_2_internal): Only invoke POINTER_TO_OFFSET on a
known character boundary. Only perform arithmetic on character positions, not
on byte positions. Correct the argument to an invocation of
UPDATE_SYNTAX_TABLE_FORWARD by adding 1 to it (in case wordend:).
* src/syntax.c: (update_syntax_table): Remove the now redundant code that set
the ->position field of all parents of the interval found by update_interval.
Add a new portable dumper as an alternative to unexec. Use it by default.
* src/dmpstruct.awk: New file.
* src/doc.c (get_doc_string): use will_dump_p().
* src/editfns.c (styled_format): silence compiler warning
with UNINIT.

init functions throughout to avoid passing explicit
'initialized' argument.

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.
This incorporates:
2017-05-16 manywarnings: update for GCC 7
2017-05-15 sys_select: Avoid "was expanded before it was required"
* configure.ac (nw): Suppress GCC 7’s new -Wduplicated-branches and
-Wformat-overflow=2 options, due to too many false alarms.
* doc/misc/texinfo.tex, lib/strftime.c, m4/manywarnings.m4:
Copy from gnulib.
* m4/gnulib-comp.m4: Regenerate.
* src/coding.c (decode_coding_iso_2022):
Fix bug uncovered by -Wimplicit-fallthrough.
* src/conf_post.h (FALLTHROUGH): New macro.
Use it to mark all switch cases that fall through.
* src/editfns.c (styled_format): Use !, not ~, on bool.
* src/gtkutil.c (xg_check_special_colors):
When using sprintf, don’t trust Gtk to output colors in [0, 1] range.
(xg_update_scrollbar_pos): Avoid use of possibly-uninitialized bool;
this bug was actually caught by Clang.
* src/search.c (boyer_moore):
Tell GCC that CHAR_BASE, if nonzero, must be a non-ASCII character.
* src/xterm.c (x_draw_glyphless_glyph_string_foreground):
Tell GCC that glyph->u.glyphless.ch must be a character.
Problem noted by Eli Zaretskii in:
http://lists.gnu.org/archive/html/emacs-devel/2017-01/msg00721.html
This patch also fixes some other issues in that report.
* src/lisp.h (incr_rarely_quit): Remove.
All callers changed to use rarely_quit directly.
* src/search.c (freeze_buffer_relocation)
(thaw_buffer_relocation): New functions.
(looking_at_1, fast_looking_at, search_buffer):
Use them to fix bug when quitting when buffers are frozen.
* src/sysdep.c (emacs_intr_read): Rename from emacs_nointr_read.
All uses changed.
This fixes some infinite loops that cannot be quitted out of,
e.g., (defun foo () (nth most-positive-fixnum '#1=(1 . #1#)))
when byte-compiled and when run under X. See:
http://lists.gnu.org/archive/html/emacs-devel/2017-01/msg00577.html
This also attempts to keep the performance improvements I recently
added, as much as possible under the constraint that the infloops
must be caught. In some cases this fixes infloop bugs recently
introduced when I removed immediate_quit.
* src/alloc.c (Fmake_list):
Use rarely_quit, not maybe_quit, for speed in the usual case.
* src/bytecode.c (exec_byte_code):

* src/fileio.c (read_non_regular, Finsert_file_contents):
* src/indent.c (compute_motion):

* src/callproc.c (call_process):
* src/doc.c (get_doc_string, Fsnarf_documentation):
* src/fileio.c (Fcopy_file, read_non_regular, Finsert_file_contents):
* src/lread.c (safe_to_load_version):
* src/sysdep.c (system_process_attributes) [GNU_LINUX]:
Use emacs_read_quit instead of emacs_read in places where
C-g handling is safe.
* src/eval.c (maybe_quit): Move comment here from lisp.h.
* src/fileio.c (Fcopy_file, e_write):
Use emacs_write_quit instead of emacs_write_sig in places where
C-g handling is safe.
* src/filelock.c (create_lock_file): Use emacs_write, not
plain write, as emacs_write no longer has a problem.
(read_lock_data): Use emacs_read, not read, as emacs_read
no longer has a problem.
* src/fns.c (rarely_quit): Move to lisp.h and rename to
incr_rarely_quit. All uses changed..
* src/fns.c (Fmemq, Fmemql, Fassq, Frassq, Fplist_put, Fplist_member):
* src/indent.c (compute_motion):
* src/syntax.c (find_defun_start, back_comment, forw_comment)
(Fforward_comment, scan_lists, scan_sexps_forward):
Use incr_rarely_quit so that users can C-g out of long loops.
* src/fns.c (Fnconc): Move incr_rarely_quit call to within
inner loop, so that it catches C-g there too.
* src/keyboard.c (tty_read_avail_input): Remove commented-out
and now-obsolete code dealing with interrupts.
* src/lisp.h (rarely_quit, incr_rarely_quit): New functions,
the latter moved here from fns.c and renamed from rarely_quit.
(emacs_read_quit, emacs_write_quit): New decls.
* src/search.c (find_newline, search_buffer, find_newline1):
Add maybe_quit to catch C-g.
* src/sysdep.c (get_child_status): Always invoke maybe_quit
if interruptible, so that the caller need not bother.
(emacs_nointr_read, emacs_read_quit, emacs_write_quit):
New functions.
(emacs_read): Rewrite in terms of emacs_nointr_read.
Do not handle C-g or signals; that is now for emacs_read_quit.
(emacs_full_write): Replace PROCESS_SIGNALS two-way arg
with INTERRUPTIBLE three-way arg. All uses changed.
The old code that sets and clears immediate_quit was
ineffective except when Emacs is running in terminal mode, and
has problematic race conditions anyway, so remove it. This
will introduce some hangs when Emacs runs in terminal mode,
and these hangs should be fixed in followup patches.
* src/keyboard.c (immediate_quit): Remove. All uses removed.
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.
Characters having both open paren syntax and comment start syntax were
being detected as open parens even when they should have been part a
comment starter (Bug#24870).
* src/syntax.c (in_2char_comment_start): New function, extracted from
`scan_sexps_forward'.
(scan_sexps_forward): Add check for a 2-char comment starter before the
loop. Inside the loop, do that check after incrementing the 'from'
character index. Move the single char comment syntax cases into the
switch instead of special casing them before.
* test/src/syntax-tests.el (parse-partial-sexp-paren-comments):
(parse-partial-sexp-continue-over-comment-marker): New tests.
* src/dired.c, src/emacs.c, src/search.c, src/syntax.c, src/thread.h:
Do not include sys/types.h; no longer needed.
* src/regex.h: Include <sys/types.h>, as that's what Gnulib and
glibc regex.h does, and POSIX has blessed this since 2008.
src/syntax.c (scan_sexps_forward): When chars of syntax word are also flagged
as the start/end of two char comment delimiters, recognize a comment delimiter
in preference to a portion of a word. This fixes bug #24767.
re_wctype function is used in three separate places and in all of
those places almost exact code extracting the name from [:name:]
surrounds it. Furthermore, re_wctype requires a NUL-terminated
string, so the name of the character class is copied to a temporary
buffer.
The code duplication and unnecessary memory copying can be avoided by
pushing the responsibility of parsing the whole [:name:] sequence to
the function.
Furthermore, since now the function has access to the length of the
character class name (since it’s doing the parsing), it can take
advantage of that information in skipping some string comparisons and
using a constant-length memcmp instead of strcmp which needs to take
care of NUL bytes.
* src/regex.c (re_wctype): Delete function. Replace it with:
(re_wctype_parse): New function which parses a whole [:name:] string
and returns a RECC_* constant or -1 if the string is not of [:name:]
format.
(regex_compile): Use re_wctype_parse.
* src/syntax.c (skip_chars): Use re_wctype_parse.

b49cb0a Fbackward_prefix_chars: stay within buffer bounds
The commit 1fd3172d "(Fbackward_prefix_chars): Set point properly while
scanning" (1998-03-18), moved the check against of the position against the
buffer beginning out the loop condition so that we might end up checking
the syntax of characters before the beginning of the buffer. This can
cause segfaults or trigger a "Point before start of properties" error in
`update_interval' (called indirectly from `char_quoted').
* src/syntax.c (Fbackward_prefix_chars): Stop the loop when beginning of
buffer is reached (Bug #3552, Bug #17132, Bug #19379).
Inspired by a suggestion from RMS in: http://bugs.gnu.org/23640#58
* .dir-locals.el (c-mode): Adjust to macro changes.
* src/conf_post.h (NONVOLATILE, UNINIT): New macros (Bug#23640).
(IF_LINT): Remove. All uses replaced by the new macros.

a5d05f4 * etc/PROBLEMS: Mention the link-time problems on FreeBSD 11.
Problem reported by Vincent Belaïche (Bug#23704).
* src/syntax.c (skip_chars): Recompute pointers into the
buffer after every call to update_syntax_table_forward,
as it can GC.
Nowadays GCC is smarter, or the Emacs code has mutated, or both,
and now is as good a time as any to remove uses of IF_LINT that
now seem to be unnecessary.

* src/xterm.c (x_connection_closed): Now _Noreturn, which should
mean we do not need IF_LINT any more.

Do this by adding a new field to the parser state: the syntax of the last
character scanned, should that be the first char of a (potential) two char
construct, nil otherwise.
This should make the parser state complete.
Also document element 9 of the parser state. Also refactor the code a bit.
* src/syntax.c (struct lisp_parse_state): Add a new field.
(SYNTAX_FLAGS_COMSTARTEND_FIRST): New function.
(internalize_parse_state): New function, extracted from scan_sexps_forward.
(back_comment): Call internalize_parse_state.
(forw_comment): Return the syntax of the last character scanned to the caller
when that character might be the first of a two character construct.
(Fforward_comment, scan_lists): New dummy variables, passed to forw_comment.
(scan_sexps_forward): Remove a redundant state parameter. Access all `state'
information via the address parameter `state'. Remove the code which converts
from external to internal form of `state'. Access buffer contents only from
`from' onwards. Reformulate code at the top of the main loop correctly to
recognize comment openers when starting in the middle of one. Call
forw_comment with extra argument (for return of syntax value of possible first
char of a two char construct).
(Fparse_partial_sexp): Document elements 9, 10 of the parser state in the
doc string. Clarify the doc string in general. Call
internalize_parse_state. Take account of the new elements when consing up the
output parser state.
* doc/lispref/syntax.texi: (Parser State): Document element 9 and the new
element 10. Minor wording corrections (remove reference to "trivial
cases").
(Low Level Parsing): Minor corrections.
* etc/NEWS: Note new element 10, and documentation of element 9 of parser
state.
