Problem reported by Glenn Morris in:
https://lists.gnu.org/r/emacs-devel/2019-08/msg00300.html
* src/lisp.h (lisp_h_make_fixnum): Use typeof (+(n)) instead
of typeof (n), so that it works with compilers that do
not allow typeof to be applied to a bitfield.
When converting from float to (TICKS . HZ) form, do the
conversion exactly. When converting from (TICKS . HZ) form to
float, round to even precisely. This way, successfully
converting a float to (TICKS . HZ) and back yields a value
numerically equal to the original.
* src/timefns.c (flt_radix_power_size): New constant.
(flt_radix_power): New static var.
(decode_float_time): Convert the exact numeric value rather
than guessing TIMESPEC_HZ resolution.
(s_ns_to_double): Remove; no longer needed.
(frac_to_double): New function.
(decode_ticks_hz): It is now the caller’s responsibility to
pass a valid TICKS and HZ. All callers changed.
Use frac_to_double to round (TICKS . HZ) precisely.
(decode_time_components): When decoding nil, use
decode_ticks_hz since it rounds precisely.
(syms_of_timefns): Initialize flt_radix_power.
* test/src/timefns-tests.el (float-time-precision): New test.
With --enable-checking, make_fixnum (N) now checks that N is
in fixnum range. Suggested by Pip Cet in:
https://lists.gnu.org/r/emacs-devel/2019-07/msg00548.html
A new function make_ufixnum (N) is for the rare cases where N
is intended to be unsigned and is in the range 0..INTMASK.
* configure.ac (AC_C_TYPEOF): Add.
(HAVE_STATEMENT_EXPRESSIONS): Resurrect this macro.
* src/fns.c (Frandom, hashfn_eq, hashfn_equal, hashfn_user_defined):
* src/profiler.c (hashfn_profiler):
Use make_ufixnum rather than make_fixum, since the argument is
an unsigned integer in the range 0..INTMASK rather than a signed
integer in the range MOST_NEGATIVE_FIXNUM..MOST_POSITIVE_FIXNUM.
Typically this is for hashes.
* src/lisp.h (lisp_h_make_fixnum_wrap) [USE_LSB_TAG]:
Rename from lisp_h_make_fixnum.
(lisp_h_make_fixnum): Redefine in terms of lisp_h_make_fixnum_wrap.
Check for fixnum overflow on compilers like GCC that
have statement expressions and typeof.
(FIXNUM_OVERFLOW_P): Move up.
(make_fixnum): Check for fixnum overflow.
(make_ufixnum): New function, which checks that the arg
fits into 0..INTMASK range.
* src/alloc.c (free_cons):
* src/casefiddle.c (do_casify_multibyte_string):
* src/editfns.c (styled_format):
* src/image.c (png_load_body):
Remove recent workarounds for INT_ADD_WRAPV bugs since
the bugs have been fixed (Bug#37006).
* etc/themes/manoj-dark-theme.el (manoj-dark): Don't alter the
height of function name faces, because this makes many tabulated
modes not longer line up (bug#17042).
* lisp/url/url-http.el (url-http-parse-headers): Narrow the
buffer to the headers at the beginning to make sure
url-handle-content-transfer-encoding uses the correct
headers. (Bug#37023)
This builds on the previous patch.
* src/alloc.c (consing_until_gc): Now of type intmax_t,
since gc-cons-threshold can be up to INTMAX_MAX. All uses changed.
* src/lisp.h (CONSING_CT_MAX, consing_ct): Remove.
Suggested by Eli Zaretskii (Bug#37006#46).
* src/alloc.c (consing_until_gc): Now of type consing_ct.
All uses changed, so gc-cons-threshold no longer saturates
against OBJECT_CT_MAX.
(object_ct): Move typedef here from lisp.h.
* src/lisp.h (consing_ct, CONSING_CT_MAX): New type and macro.
(OBJECT_CT_MAX): Remove. Replace all uses with CONSING_CT_MAX.
Problem reported by Eli Zaretskii (Bug#37006#25).
* src/alloc.c (garbage_collect_1): Fix typo in threshold calc.
Go back to dividing by 10 since the numerator’s a constant now.
Problem introduced in 2019-07-21T02:40:03Z!eggert@cs.ucla.edu.
* src/fringe.c (gui_init_fringe): Rename from w32_init_fringe
or x_cr_init_fringe, and make unconditionally compiled; all
callers changed. Do nothing if the frame's
redisplay_interface doesn't implement the define_fringe_bitmap
method. Set up any user-defined fringe bitmaps in addition to
the standard bitmaps.
Suggested by Liam Quinlan <liamkquinlan@gmail.com> in
https://lists.gnu.org/archive/html/emacs-devel/2019-08/msg00259.html.
(w32_reset_fringes) [HAVE_NTGUI]: Do nothing if the frame's
redisplay_interface doesn't implement the
destroy_fringe_bitmap method.
* src/w32fns.c (Fx_create_frame): Call gui_init_fringe when
the first GUI frame is created for this session.
* src/dispextern.h (w32_init_fringe): Rename to
gui_init_fringe and make unconditional.
(x_cr_init_fringe): Remove prototype.
* src/alloc.c (free_cons):
* src/casefiddle.c (do_casify_multibyte_string):
* src/editfns.c (styled_format):
* src/image.c (png_load_body):
Use signed arguments to INT_MULTIPLY_WRAPV etc. This doesn’t fix
any bugs, but GCC emits better code when all args are signed.
Also, this removes the need for an if in free_cons (Bug#37006).
* lisp/net/tramp-compat.el (tramp-compat-file-attribute-access-time)
(tramp-compat-file-attribute-status-change-time): New defaliases.
* test/lisp/net/tramp-tests.el (tramp--test-start-time): New defvar.
(tramp--test-file-attributes-equal-p)
(tramp-test19-directory-files-and-attributes): Use it.
(tramp-test18-file-attributes)
(tramp--test-file-attributes-equal-p, tramp-test20-file-modes)
(tramp-test22-file-times, tramp--test-check-files):
Use `tramp-compat-file-attribute-*' functions.
