This patch is just for performance; it should not affect behavior.
On my platform, it made the microbenchmark (format "%S" load-path)
run about 45% faster. It should also speed up calls like (message
"%s" STRING).
* src/callint.c (Fcall_interactively):
* src/dbusbind.c (XD_OBJECT_TO_STRING):
* src/editfns.c (Fmessage, Fmessage_box):
* src/xdisp.c (vadd_to_log, Ftrace_to_stderr):
Use styled_format instead of Fformat or Fformat_message,
to avoid unnecessary copying.
* src/editfns.c (styled_format): New arg NEW_RESULT.
All uses changed. Reuse an input string if it has the
right value and if !NEW_RESULT.
* src/lisp.h (style_format): New decl.
* src/nsterm.m (EmacsView::updateFrameSize): Don't wait for the
toolbar on undecorated frames.
(EmacsView::initFrameFromEmacs): Group window flags correctly.
Also add tests from the colorspacious library. Finally, catch an
errant calculation, where degrees were not being converted to radians.
* src/lcms.c (deg2rad, default_viewing_conditions):
(parse_viewing_conditions): New functions.
(lcms-cam02-ucs): Add comments pointing to references used. Expand
the docstring and explain viewing conditions. JCh hue is given in
degrees and needs to be converted to radians.
(lcms-d65-xyz): Remove. No need to duplicate this in Lisp or make the
API needlessly impure.
* test/src/lcms-tests.el: Reword commentary.
(lcms-rgb255->xyz): New function.
(lcms-cri-cam02-ucs): Fix let-binding.
(lcms-dE-cam02-ucs-silver): New test, assimilated from colorspacious.
* etc/NEWS: Describe changes.
* lisp/term/ns-win.el (mouse-wheel-scroll-amount,
mouse-wheel-progressive-speed): Set to smarter values for macOS
touchpads.
* src/nsterm.m (emacsView::mouseDown): Use precise scrolling deltas to
calculate scrolling for touchpads and mouse wheels.
(syms_of_nsterm): Add variables 'ns-use-system-mwheel-acceleration',
'ns-touchpad-scroll-line-height' and 'ns-touchpad-use-momentum'.
* src/keyboard.c (make_lispy_event): Pass on .arg when relevant.
* src/termhooks.h (event_kind): Update comments re. WHEEL_EVENT.
* lisp/mwheel.el (mwheel-scroll): Use line count.
* lisp/subr.el (event-line-count): New function.
* configure.ac (W32_LIBS): Put -lusp10 before -lgdi32, as latest
MinGW64 import libraries require that. (Bug#28493)
* src/Makefile.in: Adjust commentary to the new order of w32
libraries.
Problem reported by Richard Stallman (Bug#17406).
Based on fix suggested by Eli Zaretskii (Bug#28279#16).
* src/term.c (tty_send_additional_strings):
Use only safe accessors, to avoid crash when C-g C-g in GC.
* src/editfns.c (tzlookup): Fix sign error in %Z when a purely
numeric zone is negative (Bug#28746).
* test/src/editfns-tests.el (format-time-string-with-zone):
Add test for this bug.
* src/data.c (minmax_driver): Fix bug with (min 0 NaN), which
mistakenly yielded 0. Also, pacify GCC in a better way.
* test/src/data-tests.el (data-tests-min): Test for the bug.
This serves as the default optional argument for functions in this
library.
* src/lcms.c (lcms-d65-xyz): New variable.
(lcms-cam02-ucs): Use it. Use better word in docstring. Fix bug
color1 -> color2.
* test/src/lcms-tests.el: Add some tests for lcms-cri-cam02-ucs.
(lcms-colorspacious-d65): New variable.

list of results, to have their order as per the documentation.
(Bug#28390)
* etc/NEWS: Mention the change in the behavior of overlays-at.
* src/xdisp.c (handle_display_spec): If the display property is
wrapped in 'disable-eval' form, disable Lisp evaluation while
processing this property.
(handle_single_display_spec): Accept new argument ENABLE_EVAL_P.
If that argument is false, don't evaluate Lisp while processing
display properties.
* lisp/textmodes/enriched.el
(enriched-allow-eval-in-display-props): New defcustom.
(enriched-decode-display-prop): If
enriched-allow-eval-in-display-props is nil, wrap the display
property with 'disable-eval' to disable Lisp evaluation when the
display property is processed for display. (Bug#28350)
* lisp/gnus/mm-view.el (mm-inline-text): Re-enable processing of
enriched text.
* doc/lispref/display.texi (Display Property): Document the
'disable-eval' wrapping of 'display' properties.
* doc/emacs/text.texi (Enriched Properties): Document
'enriched-allow-eval-in-display-props'.
* etc/NEWS: Describe the security issues with Enriched Text mode
and their solution.
* src/lcms.c [WINDOWSNT]: Define types for cmsWhitePointFromTemp
and cmsxyY2XYZ function pointers.
(init_lcms_functions) [WINDOWSNT]: Load cmsWhitePointFromTemp and
cmsxyY2XYZ from liblcms2.
(cmsWhitePointFromTemp, cmsxyY2XYZ) [WINDOWSNT]: Redirect to the
corresponding function pointers.
(Flcms_temp_to_white_point): Minor stylistic changes. Doc fix.
(syms_of_lcms2): Defsubr Slcms_temp_to_white_point.
Also feed the translated color to the metric argument.
* src/xfaces.c (color-distance): Reword docstring to be more helpful.
Avoid duplicating effort in lcms2 by passing the translated 16 bit RGB
instead of the function's color arguments.
* src/w32term.c (w32_setup_relief_color, construct_mouse_click)
(w32_read_socket): Initialize variables to shut up bogus
compilation warnings from GCC 7.
* src/unexw32.c (COPY_CHUNK, COPY_PROC_CHUNK): Cast to DWORD_PTR
to avoid compiler warnings about printing signed values using %x
format spec.
* src/dispnew.c (adjust_glyph_matrix): Add eassert to avoid
compiler warning about possible NULL pointer dereference.
* src/lisp.h (pI): Tweak the definition some more for MinGW64.
* src/unexw32.c (pDWP): New macro.
(COPY_CHUNK, COPY_PROC_CHUNK): Declare 'count' as DWORD_PTR. Use
pDWP for printing values that can be either 32-bit or 64-bit wide.
* src/lisp.h (pI) [__MINGW32__]: Provide definition that will
hopefully DTRT with both MinGW64 and mingw.org's MinGW. See
http://lists.gnu.org/archive/html/emacs-devel/2017-09/msg00171.html
for the details.
* src/conf_post.h (PRINTF_ARCHETYPE) [MINGW_W64]: Separate
definition specific to MinGW64.
(PRINTF_ARCHETYPE) [__MINGW32__]: For mingw.org's MinGW, use
__mingw_printf__ in ANSI-compatible mode.
* lisp/term/w32-win.el (dynamic-library-alist): Include
association for the lcms2 library.
* src/lcms.c [WINDOWSNT]: Include windows.h and w32.h. Use
DEF_DLL_FN to define pointers to dynamically loaded lcms2
functions.
(cmsCIE2000DeltaE, cmsCIECAM02Init, cmsCIECAM02Forward)
(cmsCIECAM02Done): New macros.
(init_lcms_functions, Flcms2_available_p): New functions.
(Flcms_cie_de2000, Flcms_cam02_ucs) [WINDOWSNT]: Call
init_lcms_functions.
(syms_of_lcms2): Defsubr lcms2-available-p.
* src/w32fns.c (syms_of_w32fns): DEFSYM Qlcms2.
* configure.ac: Include lcms2 in the final report and in
emacs_config_features.
* nt/INSTALL:
* nt/INSTALL.W64: Update with the information about lcms2 library.
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.
configure.ac: Add boilerplate for configuring and detecting liblcms2.
etc/NEWS: Mention new configure option and color-distance change.
src/Makefile.in: Add references to lcms.c and liblcms.
src/emacs.c: Define lcms2 symbols.
src/lcms.c: New file.
src/lisp.h: Add declaration for lcms2.
src/xfaces.c: Add optional METRIC argument.
This changes the behavior of rename-file etc. slightly.
The old behavior mostly disagreed with the documentation, and had
a race condition bug that could allow attackers to modify victims'
write-protected directories (Bug#27986).
* doc/lispref/files.texi (Changing Files): Document that in
rename-file etc., NEWFILE is special if it is a directory name.
* etc/NEWS: Document the change in behavior.
* src/fileio.c (directory_like): Remove. All uses removed.
(expand_cp_target): Test only whether NEWNAME is a directory name,
not whether it is currently a directory. This avoids a race.
(Fcopy_file, Frename_file, Fadd_name_to_file, Fmake_symbolic_link):
Document behavior if NEWNAME is a directory name.
(Frename_file): Simplify now that the destdir behavior occurs
only when NEWNAME is a directory name.
* test/lisp/net/tramp-tests.el (tramp-test11-copy-file)
(tramp-test12-rename-file, tramp--test-check-files):
Adjust tests to match new behavior.
This partially reverts my 2016-05-30 patch. Apparently MinGW64
still requires pacifications that GCC 7.1.1 x86-64 (Fedora 26)
does not. Also, pacify tparam.c, which isn’t used on Fedora.
* lib-src/etags.c (process_file_name, TeX_commands):
* src/buffer.c (fix_overlays_before):
* src/data.c (Fmake_variable_buffer_local, cons_to_unsigned)
(cons_to_signed):
* src/editfns.c (Ftranslate_region_internal):
Prefer UNINIT to some stray value, as this simplifies
code-reading later.
* src/eval.c (CACHEABLE): New macro.
(internal_lisp_condition_case): Use it.
* src/tparam.c (tparam1): Use FALLTHROUGH to pacify GCC.
* src/window.c (window_scroll_pixel_based): If screen position is
to be preserved, make sure its recorded Y coordinate is outside
the scroll margin. (Bug#28342)
* src/w32font.c (SUBRANGE): Use unsigned arithmetic for
bit-shifting, to avoid compiler warnings.
(w32font_text_extents): Tell GCC NGLYPHS is non-negative, to avoid
a warning. For details of the warning, see
http://lists.gnu.org/archive/html/emacs-devel/2017-09/msg00093.html.
* src/term.c (keys) [WINDOWSNT]: Don't define, as it is not used
in that build.
* src/sound.c (sound_perror): Ifdef away on WINDOWSNT, as this
function is not used in that build.
* configure.ac: Disable -Wsuggest-attribute=format on MS-Windows.
