* mh-junk.el (mh-junk-process-blacklist, mh-junk-process-whitelist): Do
not call mh-next-msg.  Now that these functions are called from
mh-execute-commands, they should not change the current message pointer.
The calls to mh-next-msg are probably left over from when blacklist and
whitelist message processing was done immediately.

* src/floatfns.c (rounding_driver):
New arg fixnum_divide.  All callers changed.
(ceiling2, floor2, truncate2, round2): New functions.
Not that new, actually; these are essentially taken from Emacs 26.
(Fceiling, Ffloor, Fround, Ftruncate): Use them.

The problem can occur on 32-bit platforms with current timestamps.
* src/editfns.c (disassemble_lisp_time, decode_time_components):
Support seconds counts that are bignums.
* test/src/editfns-tests.el (editfns-tests--have-leap-seconds):
New function.
(format-time-string-with-bignum-on-32-bit): New test.

* src/lisp.h (integer_to_intmax, integer_to_uintmax): New functions.
* src/data.c (cons_to_unsigned, cons_to_signed)
(arith_driver):
* src/dbusbind.c (xd_extract_signed, xd_extract_unsigned):
* src/dispnew.c (sit_for):
* src/editfns.c (styled_format):
* src/emacs-module.c (module_extract_integer):
* src/fileio.c (file_offset):
* src/font.c (font_unparse_xlfd, Fopen_font):
* src/xdisp.c (calc_line_height_property):
* src/process.c (handle_child_signal):

* lisp/vc/vc-git.el (vc-git-grep-template): New variable, allows
changing the default arguments passed to git-grep when using
'vc-git-grep'.
* etc/NEWS: Mention 'vc-git-grep-template'.  (Bug#32549)

* lisp/server.el (server-process-filter): Handle any signal, not just
errors.

* src/eval.c (find_handler_clause): Accept a handler of t as always
matching.
(Fcondition_case):
* doc/lispref/control.texi (Handling Errors): Document this.
* etc/NEWS: Announce it.

* src/floatfns.c (rounding_driver): Fix bug when one
argument is a float and the other is a bignum.
* test/src/floatfns-tests.el (bignum-round): Test for the bug.

* src/fns.c (Fnthcdr): Use mpz_tdiv_ui and mpz_tdiv_r
instead of mpz_mod_ui and mpz_mod, as they are more efficient.

* src/alloc.c (xrealloc_for_gmp, xfree_for_gmp): Move to bignum.c.
(init_alloc): Move bignum initialization to init_bignum.
* src/bignum.c (init_bignum): Rename from init_bignum_once.
All users changed.
* src/emacs.c (main): Call init_bignum after init_alloc,
instead of calling init_bignum_once after init_bignum.

Improve arithmetic performance by avoiding bignums until needed.
Also, simplify bignum memory management, fixing some unlikely leaks.
This patch improved the performance of (+ 2 2) by a factor of ten
on a simple microbenchmark computing (+ x 2), byte-compiled,
with x a local variable initialized to 2 via means the byte
compiler could not predict: performance improved from 135 to 13 ns.
The platform was Fedora 28 x86-64, AMD Phenom II X4 910e.
Performance also improved 0.6% on ‘make compile-always’.
* src/bignum.c (init_bignum_once): New function.
* src/emacs.c (main): Use it.
* src/bignum.c (mpz): New global var.
(make_integer_mpz): Rename from make_integer.  All uses changed.
* src/bignum.c (double_to_bignum, make_bignum_bits)
(make_bignum, make_bigint, make_biguint, make_integer_mpz):
* src/data.c (bignum_arith_driver, Frem, Flogcount, Fash)
(expt_integer, Fadd1, Fsub1, Flognot):
* src/floatfns.c (Fabs, rounding_driver, rounddiv_q):
* src/fns.c (Fnthcdr):
Use mpz rather than mpz_initting and mpz_clearing private
temporaries.
* src/bignum.h (bignum_integer): New function.
* src/data.c (Frem, Fmod, Fash, expt_integer):
* src/floatfns.c (rounding_driver):
Use it to simplify code.
* src/data.c (FIXNUMS_FIT_IN_LONG, free_mpz_value):
Remove.  All uses removed.
(floating_point_op): New function.
(floatop_arith_driver): New function, with much of the guts
of the old float_arith_driver.
(float_arith_driver): Use it.
(floatop_arith_driver, arith_driver):
Simplify by assuming NARGS is at least 2.
All callers changed.
(float_arith_driver):
New arg, containing the partly converted value of the next arg.
Reorder args for consistency.  All uses changed.
(bignum_arith_driver): New function.
(arith_driver): Use it.  Do fixnum-only integer calculations
in intmax_t instead of mpz_t, when they fit.
Break out mpz_t calculations into bignum_arith_driver.
(Fquo): Use floatop_arith_driver instead of float_arith_driver,
since the op is known to be valid.
(Flogcount, Fash): Simplify by coalescing bignum and fixnum code.
(Fadd1, Fsub1): Simplify by using make_int.

* lisp/calendar/todo-mode.el (todo-add-file): Since
todo-current-todo-file must be set before calling todo-show, but
the buffer is not yet in todo-mode, which makes it buffer local,
explicitly set it buffer locally (bug#32627).

* test/lisp/calendar/todo-mode-tests.el (todo-test--add-file)
(todo-test--delete-file): New functions.
(todo-test-add-and-delete-file): New test.

Although these constants were not erroneous, as they were
used only in modules that did not include <math.h>, it's
less confusing to names that cannot be confused with
the now-standard INFINITY macro.
* src/dispextern.h (SCROLL_INFINITY): New constant.
* src/dispnew.c, src/scroll.c (INFINITY):
Remove.  All uses replaced with SCROLL_INFINITY.
* src/process.c (wait_reading_process_output):
Rename private constant.

* src/lread.c (string_to_number) [!IEEE_FLOATING_POINT]:
Do not use the INFINITY macro, since the C standard requires
it to provoke a compile-time error on platforms that do not
support infinities.

* etc/NEWS (thread-alive-p):
* lisp/emacs-lisp/thread.el (thread-alive-p): Mark it as obsolete.

* test/src/thread-tests.el (threads-join-error)
(threads-signal-main-thread): Use `thread-live-p'.

ac7936cb Rename thread-alive-p to thread-live-p
3d09d533 rcirc: Document /reconnect as a built-in command (Bug#29656)
a1e61561 * test/lisp/calc/calc-tests.el (calc-imaginary-i): New test.

* doc/lispref/threads.texi (Basic Thread Functions): Use thread-live-p.

* etc/NEWS: 'thread-alive-p' has been renamed to 'thread-live-p'.

* src/thread.c (thread_live_p): Rename from thread_alive_p.  Adapt
all callees.
(Fthread_live_p): Rename from Fthread_alive_p.
(syms_of_threads): Make thread-alive-p an alias of thread-live-p.

* test/src/thread-tests.el (all): Replace `thread-alive-p' by
`thread-live-p'.
(threads-live): Rename from `threads-alive'.

* src/bignum.c: Include stdlib.h, for abs.
(bignum_bufsize, bignum_to_c_string): New functions.
* src/bignum.c (bignum_to_string):
* src/print.c (print_vectorlike): Use them.
* src/editfns.c (styled_format): Instead of having a separate
buffer for sprintf (which does not work for bignums), just append
to the main buffer.  When formatting bignums, add support for the
standard integer flags -, #, 0, + and space.  Fix some comments.
Capitalize properly when formatting bignums with %X.  Use
functions like c_isdigit rather than reinventing the wheel.
Simplify computation of excess precision.
* src/print.c: Do not include bignum.h; no longer needed.
(print_vectorlike): Avoid recalculating string length.
* test/src/editfns-tests.el (format-bignum):
Test some of the above fixes.

* src/thread.c (Fthread_signal): Construct a thread_event only if
THREADS_ENABLED.

* src/emacs-module.c: Do not include bignum.h; no longer needed.
(module_extract_integer): Use bignum_to_intmax to avoid
incorrectly signaling overflow on platforms where intmax_t
is wider than long int.

* doc/lispref/threads.texi (Basic Thread Functions):
* etc/NEWS: Document thread-signal towards the main thread.

* lisp/emacs-lisp/thread.el: New package.

* src/keyboard.c (read_char): Check for Qthread_event.
(kbd_buffer_get_event, make_lispy_event): Handle THREAD_EVENT.

(keys_of_keyboard): Add thread-handle-event to special-event-map.

* src/termhooks.h (enum event_kind): Add THREAD_EVENT.

* src/thread.c: Include "keyboard.h".
(poll_suppress_count) Don't declare extern.
(Fthread_signal): Raise event if THREAD is the main thread.  (Bug#32502)

* test/src/thread-tests.el (thread): Require it.
(threads-signal-main-thread): New test.

* src/image.c (imagemagick_load_image): Use double division, and
eliminate a cast.  This avoids a -Wdouble-promotion warning with
GCC 7.3 on Ubuntu 18.04.

The change "New command rcirc-cmd-reconnect" from 2014-04-09 (shipped
in Emacs 25.1) added a /reconnect command to rcirc but did not
document it and did not delete the example /reconnect command
definition in the manual.
* doc/misc/rcirc.texi (rcirc commands): Document the built-in /reconnect
command.
(Hacking and Tweaking): Delete example reconnect command.
