* src/xdisp.c (resize_mini_window): Resize the mini-window
when multi-line text is displayed under truncate-lines
non-nil in the minibuffer. (Bug#46718)
Simplify closure creation by calling a single function at run time
instead of putting it together from small pieces. This is faster
(by about a factor 2), takes less space on disk and in memory, and
makes internal functions somewhat readable in disassembly listings again.
This is done by creating a prototype function at compile-time whose
closure variables are placeholder values V0, V1... which can be seen
in the disassembly. The prototype is then cloned at run time using
the new make-closure function that replaces the placeholders with
the actual closure variables.
* lisp/emacs-lisp/bytecomp.el (byte-compile-make-closure):
Generate call to make-closure from a prototype function.
* src/alloc.c (Fmake_closure): New function.
(syms_of_alloc): Defsubr it.
* src/data.c (syms_of_data): Defsym byte-code-function-p.
* lisp/emacs-lisp/byte-run.el (byte-run--set-modes): Change from
being a predicate to storing the modes. This allows using the
modes for positive command discovery, too.
* src/data.c (Fcommand_modes): Look at the `command-modes' symbol
property, too.

* src/xfns.c (x_get_net_workarea, x_get_monitor_for_frame)
(x_make_monitor_attribute_list, x_get_monitor_attributes_fallback):
[HAVE_XINERAMA] (x_get_monitor_attributes_xinerama)
[HAVE_XRANDR] (x_get_monitor_attributes_xrandr)
(x_get_monitor_attributes): Fix #ifdefs around definitions to avoid
unused function warnings regardless of GTK use (bug#46509).
[HAVE_XRANDR] (x_get_monitor_attributes_xrandr): Undefine
RANDR13_LIBRARY after it's been used.
* src/data.c (Fcommand_modes): Remove the subr bit -- it's not
necessary since it can just use a predicate.
* src/lisp.h (GCALIGNED_STRUCT): Remove command_modes.
* src/lread.c (defsubr): Remove command_modes.
* doc/lispref/commands.texi (Using Interactive): Document the
extended `interactive' form.

form.
* lisp/emacs-lisp/autoload.el (make-autoload): Pick the list of
modes from `interactive' out of the functions.
* lisp/emacs-lisp/bytecomp.el (byte-compile-lambda): Allow for the
extended `interactive' form.
* src/callint.c (Finteractive): Document the extended form.
* src/data.c (Finteractive_form): Return the interactive form in
the old format (even when there's an extended `interactive') to
avoid having other parts of Emacs be aware of this.
(Fcommand_modes): New defun.
* src/emacs-module.c (GCALIGNED_STRUCT): Allow for modules to
return command modes.
* src/lisp.h: New function module_function_command_modes.
; Incidentally fixes bug#21326.
* src/nsterm.m ([EmacsView viewWillDraw]): New function.
([EmacsView viewDidResize:]): We now have to mark the frame for
display on resize.
([EmacsView initFrameFromEmacs:]): Retain frame contents on resize.
([EmacsView updateLayer]): Don't update the layer if the frame is
still garbaged.
* src/image.c (FRAME_SCALE_FACTOR): New #define for getting frame
scale factor.
(image_set_transform):
(svg_load_image): Use FRAME_SCALE_FACTOR.
* src/nsterm.m (ns_frame_scale_factor): Get the scale factor for an NS
frame.
The JSON serialization and parsing functions don't need to modify
these structures.
* src/json.c (lisp_to_json_nonscalar_1, lisp_to_json_nonscalar)
(lisp_to_json, json_to_lisp): Mark configuration object parameter as
const.
Newer standards like RFC 8259, which obsoletes the earlier RFC 4627,
now allow any top-level value unconditionally, so Emacs should too.
* src/json.c (Fjson_serialize, Fjson_insert): Pass JSON_ENCODE_ANY to
allow serialization of any JSON value. Call 'lisp_to_json' instead of
'lisp_to_json_toplevel'. Remove obsolete comments
(neither JSON_DECODE_ANY nor JSON_ALLOW_NUL are allowed here). Reword
documentation strings.
(Fjson_parse_string, Fjson_parse_buffer): Pass JSON_DECODE_ANY to
allow deserialization of any JSON value. Reword documentation
strings.
(lisp_to_json_nonscalar, lisp_to_json_nonscalar_1): Rename from
"toplevel" to avoid confusion.
(lisp_to_json): Adapt caller.
* test/src/json-tests.el (json-serialize/roundtrip-scalars): New unit
test.
* doc/lispref/text.texi (Parsing JSON): Update documentation.
* src/xdisp.c (move_it_in_display_line_to): Consider it
MOVE_POS_MATCH_OR_ZV if we are just after an image, stretch, or
display string, and the position matches exactly. This is needed
when one image follows another at TO_CHARPOS. (Bug#46464)
* lisp/minibuffer.el (exit-minibuffer): When in a minibuffer, throw an error
should the command loop nesting level be wrong.
* src/lisp.h (minibuffer_quit_level): declare as an extern.
(command_loop_level): Move definition from src/window.h
* src/window.h (command_loop_level): move definition to src/lisp.h.
* src/eval.c (minibuffer_quit_level): Move this variable to file level from
being a static inside internal_catch.
(internal_catch): Simplify the logic.
* src/minibuf.c (Vcommand_loop_level_list): New variable.
(move_minibuffer_onto_frame): Set the major mode of *Minibuf-0*.
(Fminibuffer_innermost_command_loop_p): New primitive.
(Fabort_minibuffers): Check the command loop level before throwing t to 'exit,
and set minibuffer_quit_level too.
(read_minibuf): New variable calling_window.
Before stacking up minibuffers on the current mini-window, check that the
mini-window is not the current one.
Do not call choose_minibuf_frame from read_minibuf's unwinding process.
Bind calling_frame and calling_window over the recursive edit.
Set the new minibuffer's major mode directly.
Remove the switching away from the minibuffer after the recursive edit.
(get_minibuffer): Record the command loop level in new variable
Vcommand_loop_level_list. No longer set the major mode of a returned
minibuffer.
(minibuf_c_loop_level): New function.
(read_minibuf_unwind): New variables calling_frame, calling_window are unbound
from the binding stack. Remove old variable `window', which could not be set
reliably to the expired mini-window.
The expired minibuffer is determined as the nth in the list, rather than the
contents of the current or previous mini-window.
Switch the current window away from the mini-window here (moved from
read_minibuf).
* src/lread.c (syms_of_lread): Note that it's obsolete in the doc
string (because we can't mark it as obsolete "properly" yet,
because that leads to compilation warnings when somebody
(let (values) ... values).
* src/xdisp.c (try_window): Don't try checking the margins if the
window is vscrolled, as that could cause unnecessary recentering
when tall images are displayed. (Bug#46320)
These changes improve setting the language-environment and font
selection when MS-Windows returns useless "ZZZ" as the "language
name", which then disrupts all the setup of the locale-dependent
stuff, and in particular font selection.
* lisp/w32-fns.el (w32-charset-info-alist): Add an element for
"iso8859-5", in case LANG is set to something unusable, like
"ZZZ". This allows fonts capable of displaying Cyrillic
characters to be used even when language preferences are screwed.
* src/w32.c (init_environment): If GetLocaleInfo returns "ZZZ" as
the "language name" for LOCALE_USER_DEFAULT, try again with locale
ID based on what GetUserDefaultUILanguage returns. (Bug#39286)
* doc/lispref/positions.texi (Text Lines): Revert previous change.
* lisp/simple.el (line-number-at-pos): Remove definition.
* lisp/simple.el (count-lines): Revert back to using
`forward-line', because there seems to be a disagreement on how
lines should be counted in a region...
* src/fns.c (Fline_number_at_pos): Rename from
Fline_number_at_position and adjust parameter list.
* doc/lispref/positions.texi (Text Lines): Document it.
* lisp/simple.el (count-lines): Use it.
(line-number-at-pos): Ditto.
* src/fns.c (Fline_number_at_position): New function (bug#22763).
* doc/lispref/frames.texi (Layout Parameters): Update entry on
'child-frame-border-width' parameter.
* src/frame.c (make_frame): Init child_frame_border_width to -1.
(Fframe_child_frame_border_width): Return internal border width if
child frame border width parameter is nil.
(gui_report_frame_params): Report nil as child frame border
width parameter if the frame value is negative.
* src/frame.h (FRAME_INTERNAL_BORDER_WIDTH): Return value of
child frame border width only if it is not negative.
* src/xfns.c (Fx_create_frame): Default child frame border to -1
when recording it in its frame slot via gui_default_parameter.
* src/nsfns.m (ns_set_child_frame_border_width): Handle nil ARG.
(Fx_create_frame): Default child frame border width parameter to
nil.
* src/w32fns.c (w32_set_child_frame_border_width): Handle nil ARG.
(Fx_create_frame): Default child frame border width parameter to
nil.
* src/xfns.c (x_set_child_frame_border_width): Handle nil ARG.
(Fx_create_frame): Default child frame border width parameter to
nil.
* src/editfns.c (styled_format): Fix accounting for text
properties that come from the format string. (Bug#46317)
* test/src/editfns-tests.el (format-properties): Add new tests for
bug#46317.
* src/xdisp.c (Fwindow_text_pixel_size): Fix last change: preserve
the original Y coordinate after start_display, instead of zeroing
it out. Reported by martin rudalics <rudalics@gmx.at>.
* src/lread.c (Fread_char, Fread_event, Fread_char_exclusive):
Call cancel_echoing to make sure the prompt is not obscured by
keystrokes echo. (Bug#46243)
* src/xdisp.c (Fwindow_text_pixel_size): Support the use case
where FROM and TO belong to the same screen line. Reported by
Yuan Fu <casouri@gmail.com>.
* src/lread.c (invalid_syntax_lisp): Instead of putting the
line/column in a string, signal an error containing the numbers as
data. This allows for easier post-processing and is how other
similar errors (like (forward-sexp 1)) do it.
* src/lisp.h: Add count_lines prototype.
* src/lread.c (invalid_syntax_lisp): New function (bug#36970).
(invalid_syntax): Extend function to take a readcharfun parameter.
(read_emacs_mule_char, character_name_to_code): Pass in.
(read_escape, invalid_radix_integer, read1): Ditto.
* src/xdisp.c (count_lines): Add a more succinct shim over
display_count_lines.
src/minibuf.c (get_minibuffer): Move the XSETCAR which writes the new
minibuffer into Vminibuffer_list to immediately after the MB's creation, so
that the list is in a consistent state before calling fundamental-mode or
minibuffer-inactive-mode.
