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.
* src/alloc.c (purecopy_hash_table):
* src/fns.c (maybe_resize_hash_table, Fmake_hash_table):
(Fhash_table_rehash_size):
* src/lisp.h (struct Lisp_Hash_Table.rehash_size):
The rehash_size member of struct Lisp_Hash_Table is now a
float, not a Lisp_Object.
* src/alloc.c (purecopy_hash_table): Assign members in order.
* src/fns.c (make_hash_table): Use EMACS_INT for size and
float for rehash_size, instead of Lisp_Object for both.
All callers changed.
* src/lisp.h (DEFAULT_REHASH_SIZE): Now float, not double,
and 1 smaller.
* src/print.c (print_object): Simplify by calling
Fhash_table_rehash_size and Fhash_table_rehash_threshold.
Avoid unnecessary NILP.
* src/alloc.c (purecopy_hash_table): Assign, don’t purecopy.
* src/fns.c (set_hash_next_slot, set_hash_index_slot): Hash index
arg is now ptrdiff_t index (or -1 if empty), not Lisp_Object
integer (or Qnil if empty). All callers changed.
(larger_vecalloc): New static function.
(larger_vector): Use it.
(HASH_NEXT, HASH_INDEX): Move here from lisp.h. Return ptrdiff_t

of the free list. Reallocate H->next last, in case other
reallocations exhaust memory.

(purecopy_hash_table) New function, makes a copy of the given hash
table in pure storage.
Add new struct `pinned_object' and `pinned_objects' linked list for
pinning objects.
(Fpurecopy) Allow purifying hash tables
(purecopy) Pin hash tables that are either weak or not declared with
`:purecopy t`, use purecopy_hash_table otherwise.
(marked_pinned_objects) New function, marks all objects in pinned_objects.
(garbage_collect_1) Use it. Mark all pinned objects before sweeping.

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.
This was inspired by commit e65c3079c6,
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.

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.

* src/profiler.c [CYGWIN] (timer_getoverrun): Define as a macro on
Cygwin.

return -1 if the sampling interval is invalid.
(Fprofiler_cpu_start): Improve error message if 'setup_cpu_timer'
fails. (Bug#20843)
Fixes Bug#15880.

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

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.

Use plain DEFSYM for Qt and Qnil.
* syntax.c (init_syntax_once): No need to worry about
Qchar_table_extra_slots.

it remains 1 ms.
(profiler-report-cpu-line-format): Give enough room for
the maximum counters on 64-bit hosts.
(profiler-report-render-calltree-1): Call them "CPU samples",
not "Time (ms)", since they are not milliseconds now (and
never really were).
* src/profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
Give extra weight to samples after overruns, to attempt to count
the time more accurately.
(setup_cpu_timer): Change sampling interval units from ms to ns, since

* profiler.c: Don't include stdio.h, limits.h, sys/time.h,
signal.h, setjmp.h. Include systime.h instead.
(saturated_add): New function.
(record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.
(record_backtrace, handle_profiler_signal): Saturate on fixnum overflow.
(profiler_timer, profiler_timer_ok) [HAVE_TIMER_SETTIME]:
New static vars.
(enum profiler_cpu_running): New enumn.
(profiler_cpu_running): Now of that enum type, not bool.
All uses changed to store the new value.
(handle_profiler_signal): Rename from sigprof_handler_1,
for consistency with other handlers. Do not check whether
cpu_log is a hash-table if garbage collecting, since it
doesn't matter in that case.
(deliver_profiler_signal): Rename from sigprof_handler,
for consistency with other handlers.
(setup_cpu_timer): New function, with much of what used to be in
Fprofiler_cpu_start. Check for out-of-range argument.
Prefer timer_settime if available, and prefer
thread cputime clocks, then process cputime clocks, then
monotonic clocks, to the old realtime clock. Use make_timeval
to round more-correctly when falling back to setitimer.
(Fprofiler_cpu_start): Use it.
(Fprofiler_cpu_stop): Prefer timer_settime if available.
Don't assume that passing NULL as the 2nd argument of setitimer
is the same as passing a pointer to all-zero storage.
Ignore SIGPROF afterwards.
(malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
* sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
non-fatal signal handlers. Ignore SIGPROF on startup.
* syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
in profiler.c, since sysdep.c now uses it.
isn't any.
(profiler-stop): Use new semantics of profiler-*-stop.
(profiler-reset, profiler--report-cpu): Don't signal an error if the
cpu profiler is not available.
* src/profiler.c (Fprofiler_cpu_stop, Fprofiler_memory_stop):
Return whether the profiler was running, instead of signaling an error
if it wasn't.
* src/profiler.c (evict_lower_half): Fix typo.
(PROFILER_CPU_SUPPORT): Check and define if cpu-profiler is supported.
Don't compile the cpu-profiler code, if not supported.
(malloc_probe): Presume memory_log is non-nil.
(syms_of_profiler): Don't defsubr functions when they aren't defined.
* src/lisp.h (sample_profiler_running, gc_probe): Don't declare.
* src/profiler.c: Remove filtering functionality.
(is_in_trace, Qgc): Remove vars.
(make_log, record_backtrace, Fsample_profiler_log):
Rewrite, using Elisp hash-tables.
(approximate_median, evict_lower_half): New functions.
(cpu_log): Rename from sample_log.
(cpu_gc_count): New var.
(Fsample_profiler_reset, Fmemory_profiler_reset): Remove.
(sigprof_handler): Add count to cpu_gc_count during GC, detected via
backtrace_list.
(block_sigprof, unblock_sigprof): Remove.
(gc_probe, mark_profiler): Remove functions.
(syms_of_profiler): Staticpro cpu_log and memory_log.
* lisp/profiler.el (profiler-sample-interval): Move before first use.
Change default to 1ms.
(profiler-entry=, profiler-backtrace-reverse, profiler-log-fixup-slot)
(profiler-calltree-elapsed<, profiler-calltree-elapsed>): Remove functions.
(profiler-entry-format): Don't use type-of.
(profiler-slot, profiler-log): Remove structs.
(profiler-log-timestamp, profiler-log-type, profiler-log-diff-p):
Redefine for new log representation.
(profiler-log-diff, profiler-log-fixup, profiler-calltree-build-1):
Rewrite for new log representation.
(profiler-calltree): Remove `elapsed' fields.
(profiler-calltree-count<, profiler-report-make-entry-part):
Remove gc special case.
(profiler-calltree-find): Use equal.
(profiler-calltree-walk): Remove `args'; rely on closures instead.
(profiler-calltree-compute-percentages-1): Remove; inlined.
(profiler-calltree-compute-percentages): Simplify.
(profiler-report-log, profiler-report-reversed)
(profiler-report-order): Use defvar-local.
(profiler-report-line-format): Remove `elapsed', do a bit of CSE.
(profiler-report-mode-map): Remove up/down bindings.
(profiler-report-make-buffer-name): Simplify by CSE.
(profiler-report-mode): Remove redundant code.
(profiler-report-expand-entry, profiler-report-collapse-entry):
Use inhibit-read-only.
(profiler-report-render-calltree-1): Simplify by CSE.
(profiler-reset): Rewrite for new subroutines.
(profiler--report-cpu): Rename from sample-profiler-report.
(profiler--report-memory): Rename from memory-profiler-report.
* src/alloc.c (Fgarbage_collect): Record itself in backtrace_list.
Don't set is_in_trace any more. Don't call mark_profiler.
Only call gc_probe for the memory profiler.
(syms_of_alloc): Define Qautomatic_gc.
* src/lisp.h (SXHASH_COMBINE): Move back to...
* src/fns.c (SXHASH_COMBINE): ...here.
* src/xdisp.c (Qautomatic_redisplay): New constant.
(redisplay_internal): Record itself in backtrace_list.
(syms_of_xdisp): Define Qautomatic_redisplay.
* .dir-locals.el (indent-tabs-mode): Remove personal preference.
