Without this patch, it was theoretically possible for a list
length to be a bignum, which means that safe-length could
signal an error (due to generating a too-large bignum) contrary
to its documentation. Fix things to remove the theoretical
possibility, so that list lengths are always fixnums (and so
that list lenghts are always ptrdiff_t values too, since that
is assumed internally anyway).
* src/alloc.c (Fcons): Do not allocate so many conses that
a list length won’t fit into ptrdiff_t or into fixnum.
This matters only on weird platforms; on typical platforms,
list lengths always fit anyway.
* src/fns.c (list_length, Fsafe_length, proper-list-p):
Remove integer overflow checks that are no longer needed.
This mostly just reindents.
* src/image.c (x_set_image_size): Always define, but to a no-op
if !HAVE_NATIVE_SCALING, to avoid an #ifdef elsewhere.
(x_create_x_image_and_pixmap): Move decl to avoid an #ifdef.
(image_create_x_image_and_pixmap): Move #ifdef outside of call.
* src/xterm.c (x_composite_image): Avoid ‘else #endif’.
* configure.ac: Test for XRender outside of xft checks.
* src/Makefile.in (XRENDER_LIBS): List XRender libs separately from
xft libs.
* lisp/image.el (image--get-imagemagick-and-warn): Allow resizing if
native scaling is available.
* src/dispextern.h: Add XRender and image scaling stuff.
(struct image): Add XRender Pictures.
* src/image.c (x_create_bitmap_mask):
(image_create_x_image_and_pixmap): Handle XRender Picture.
(scale_image_size):
(compute_image_size): Make available when any form of scaling is
enabled.
(x_set_image_size): New function.
(lookup_image): Set image size.
(x_create_x_image_and_pixmap): Create XRender Picture when necessary.
(x_put_x_image): Handle the case where desired size != actual size.
(free_image): Free XRender Pictures.
(Fimage_scaling_p): New function.
(syms_of_image): Add image-scaling-p.
* src/nsimage.m (ns_load_image): Remove NS specific resizing.
([EmacsImage setSizeFromSpec:]): Remove method.
(ns_image_set_size): New function.
* src/nsterm.m (ns_draw_fringe_bitmap): Cocoa and GNUstep both have
the same compositing functions, so remove unnecessary difference.
* src/xterm.c (x_composite_image): New function.
(x_draw_image_foreground): Use new x_composite_image function.
* doc/lispref/display.texi (Image Descriptors): Document
image-scaling-p and add resizing descriptors.
(ImageMagick Images): Remove resizing descriptors.
* doc/emacs/macos.texi (Mac / GNUstep Events): Describe the new drag
and drop behaviour.

(ns-drag-n-drop-other-frame):
(ns-drag-n-drop-as-text):
(ns-drag-n-drop-as-text-other-frame): Remove functions and key
bindings.

in new format without setting any modifiers.

(custom--test-variable): New variables.
(custom--test-theme-variables): New test.
* test/lisp/custom-resources/custom--test-theme.el (custom--test):
New file.
* lisp/window.el (display-buffer-record-window): Rewrite
doc-string.
(window--display-buffer): Remove fifth argument DEDICATED and
either directly use a 'dedicated' entry in ALIST or the value
of 'display-buffer-mark-dedicated' instead.
(display-buffer-in-atom-window, display-buffer-use-some-frame)
(display-buffer-pop-up-frame, display-buffer-pop-up-window)
(display-buffer-below-selected, display-buffer-at-bottom):
Adjust callers of 'window--display-buffer'.
(window--make-major-side-window)
(display-buffer-in-side-window): Handle dedicated status of
the chosen side window via a 'dedicated' alist entry and
adjust 'window--display-buffer' call.
(display-buffer-in-child-frame): Set up TYPE correctly for and
adjust 'window--display-buffer' call.
(display-buffer-in-previous-window): Handle dedicated status
of a previous window already showing BUFFER.

entry 'dedicated'.

'dedicated'.
* lisp/language/japan-util.el (setup-japanese-environment-internal):
Use utf-8 as preferred coding system instead of japanese-iso-8bit when
system is not MS-Windows. And while I'm at it, fix comment to fit current
implementation. (Bug#28705)
Copyright-paperwork-exempt: yes.
When calculating the length of a Lisp object whose type is
known, use a specialized length operation on it to save a bit
of runtime overhead.

The following commits were skipped:
13b586d (origin/emacs-26) Adapt filenotify-tests for emba
d8525ae (tag: emacs-26.1.91) Bump Emacs version to 26.1.91
Change logb to return -infinity, +infinity, and NaN respectively.
Formerly logb returned an extreme fixnum to represent
infinity, but this is no longer the right thing to do now that
we have bignums and there is no extreme integer.
* doc/lispref/numbers.texi (Float Basics), etc/NEWS: Document.
* src/floatfns.c (Flogb): Implement this.
* lisp/emacs-lisp/syntax.el (syntax-ppss-stats):
Use integers, not floating-point, for stats, now that integers are
unbounded. Almost always these should be fixnums. Add 1 to last
slot’s car so that this addition need not be done at runtime.
(syntax-pps-stats, syntax-ppss): Use integers for calculations.
(syntax-ppss--update-stats): New convenience function.
(syntax-ppss): Use it.
A feature suggested by Yuri Khan <yurivkhan@gmail.com>.
* lisp/progmodes/flymake.el (flymake-suppress-zero-counters): New
variable. (flymake--mode-line-format): Use it.
