* src/buffer.c (syms_of_buffer): Two new variables,
'long-line-locked-narrowing-region-size' and
'long-line-locked-narrowing-bol-search-limit', to make the locked
narrowing around low-level hooks configurable.
Increase the default value of 'long-line-threshold'. After
carefully considering the (few) bug reports about long line
optimizations, I concluded that the previous default value was too
low.
* src/xdisp.c (get_locked_narrowing_begv)
(get_locked_narrowing_zv): Two new functions.
(handle_fontified_prop, reseat): Use them.
* src/keyboard.c (safe_run_hooks_maybe_narrowed): Use them.
* src/dispextern.h (struct it): Add two new fields to store the
values returned by these functions.
Make them externally visible.
* src/editfns.c: (Fsave_restriction): Update docstring.
* src/editfns.c: (Fsave_restriction): Save and restore narrowing
locks. Suggested by Stefan Monnier.
(narrowing_locks_save, narrowing_locks_restore): Helper functions.
* lisp/subr.el (with-narrowing-1): Simplify.
* lisp/subr.el (with-narrowing): New generic macro, replacing the
'with-locked-narrowing' one. Suggested by Stefan Monnier.
(with-narrowing-1, with-narrowing-2): Helper functions.
* src/editfns.c: (narrowing_locks): New alist to hold the narrowing
locks and their buffers.
(narrowing_lock_get_bound, narrowing_lock_peek_tag)
(narrowing_lock_push, narrowing_lock_pop): New functions to access
and update 'narrowing_locks'.
(reset_outermost_narrowings, unwind_reset_outermost_narrowing):
Functions moved from src/xdisp.c, and rewritten with the above
functions.
(Fwiden): Use the above functions. Update docstring.
(Fnarrow_to_region, Fnarrowing_lock, Fnarrowing_unlock): Use the above
functions.
(syms_of_editfns): Remove the 'narrowing-locks' variable.
* src/lisp.h: Make 'reset_outermost_narrowings' externally visible.
* src/xdisp.c (reset_outermost_narrowings)
unwind_reset_outermost_narrowing): Functions moved to src/editfns.c.
* lisp/subr.el (with-locked-narrowing): Improved macro, with a helper
function.
* lisp/filesets.el (filesets-update-pre010505): Make update
information for filesets older than 2001 obsolete. Note that this
dates back to before filesets.el was even added to Emacs.
(outline-font-lock-keywords, outline-font-lock-face)
(outline-minor-mode-highlight-buffer, outline-next-preface)
(outline-next-heading, outline-previous-heading)
(outline-back-to-heading, outline-on-heading-p, outline-demote)
(outline-map-region, outline-next-visible-heading)
(outline-hide-sublevels, outline-up-heading): Use outline-search-function
when it's non-nil as an alternative to searching outline-regexp.
(outline-search-level, outline-search-text-property): New functions.
* lisp/apropos.el (apropos-mode): Set outline-search-function
instead of unreliable outline-regexp.
(apropos-print): Add text property outline-level.
* lisp/emacs-lisp/shortdoc.el (shortdoc-display-group):
Add text property outline-level on text separate from final newlines.
(shortdoc-display-group): Add a narrow newline to not show
text properties of the final line when the outline is hidden.
(shortdoc--display-function): Add text property outline-level.
(shortdoc-mode): Set buffer-local outline-search-function and outline-level.
* src/lread.c (maybe_swap_for_eln): Use a delayed warning
instead of `display-warning' to avoid a recursive call to
Fload while loading the init file that sets `user-init-file'
to a bogus value.
* lisp/progmodes/elisp-mode.el (elisp-eval-region-or-buffer):
Rename recently added command 'elisp-eval-buffer' to support active region.
(emacs-lisp-mode-map, lisp-interaction-mode-map): Rebind 'C-c C-e'
from elisp-eval-buffer to elisp-eval-region-or-buffer.
Also, write more commentary.
* src/xterm.c (xi_populate_scroll_valuator): New function.
Describe the meaning of each field in xi_scroll_valuator_t.
(xi_populate_device_from_info, xi_handle_new_classes): Factor
out duplicate code to that function.
* doc/lispref/internals.texi (Garbage Collection):
* src/alloc.c (syms_of_alloc) <gc-cons-threshold>
<gc-cons-percentage>: Advise against enlarging the GC thresholds
more than needed and for prolonged periods of time.
* lisp/server.el (server-start): Use 'locale-coding-system' to
encode messages sent back to the client.
* lib-src/emacsclient.c (main): Print '-error' messages via
'message', not directly via 'fprintf'. This shows the error on
MS-Windows when the client is invoked as 'emacsclientw', since
stderr goes to the bit bucket in that case.
* lisp/face-remap.el (global-text-scale-adjust): Try again if the face
height should have changed but did not actually change. Update the
docstring to clarify the difference with 'text-scale-adjust'.
(global-text-scale-adjust--increment-factor): New internal variable.
Fixes bug#59122.
(text-scale-adjust): Update the docstring to clarify the difference
with 'global-text-scale-adjust'.
* src/xfns.c (x_set_mouse_color): Use
x_uncatch_errors_after_check right after x_had_errors_p. Then,
trap errors around FreeCursor requests, since some of the IDs
may not name valid cursors.
* src/xterm.c (x_fast_mouse_position): New function. Factor out
most of the fast mouse position code here. Correctly port some
Haiku code to take into account multiple displays. Report
scroll bar coordinates correctly.
(XTmouse_position): Call it.
* lisp/faces.el (x-create-frame-with-faces): New field
`delayed-font'. Set the `font-parameter' property to `font' in
the given parameter list after face-set-after-frame-default is
called.
* src/fontset.c (Fset_fontset_font): Avoid changing
`font-parameter' with the call to Fmodify_frame_parameters.
* src/frame.c (gui_set_frame_parameters_1): New function.
Factor out gui_set_frame_parameters here, and add an argument
DEFAULT_PARAMETER. If the `font' parameter is set, and
`default_parameter' is not, then set the `font-parameter' frame
parameter to the `font' parameter as well, to keep track of
which user-specified `font' frame parameter set the default
face's font on the frame.
(gui_set_frame_parameters): Call gui_set_frame_parameters_1 with
new arg set to false.
(gui_set_font): Remove broken implementation of
`font-parameter'.
(gui_default_parameter): If the default value was used, then
call gui_set_frame_parameters_1 with the new argument set to
false. This is because no font was specified as a frame
parameter by the user, so Freconsider_frame_fonts is free to do
anything it wants.
(Freconsider_frame_fonts): If `font-parameter' is set, then use
it.
(syms_of_frame): New defsym Qfont_parameter.
* src/frame.h: Update prototypes.
* src/haikuterm.c (haiku_default_font_parameter):
* src/pgtkfns.c (pgtk_default_font_parameter):
* src/w32fns.c (w32_default_font_parameter): Stop setting
`font-parameter' here. This code resulted in decades of
automatic font rescaling not working correctly.
* src/xfaces.c (set_font_frame_param): Clear the
`font-parameter' frame parameter.
(Finternal_merge_in_global_face):
* src/xfns.c (x_default_font_parameter): Avoid changing
`font-parameter' in response to changes to face attributes.
* src/xsettings.c (apply_xft_settings): Add workaround for
Cairo. (bug#59371, bug#59347, bug#59283, bug#59271, bug#59285,
bug#59306.)
* src/frame.c (Freconsider_frame_fonts): If a font parameter was
set, create a params alist with it. Then, pass it to both
default_font_parameter and face-set-after-frame-default.
(bug#59371)
* src/keyboard.c (coords_in_menu_bar_window): New function.
(make_lispy_event): Do not process menu bar events on window
system frames if there is no menu bar window or the click lies
outside.
* src/keyboard.c (make_lispy_event): Use x_y_to_hpos_vpos to
compute correct menu bar position should the menu face change.
* src/xdisp.c (x_y_to_hpos_vpos): Not static anymore.
* src/dispextern.h: Export x_y_to_hpos_vpos.
* src/buffer.c (delete_all_overlays): Use POST_ORDER to set the node's
pointers to NULL, as god intended.
* src/itree.c (itree_insert_node): Uncomment the assertion accordingly.
