* src/keyboard.c (prev_kbd_event): Now defined only if HAVE_X11.
* lisp/subr.el (while-no-input-ignore-events): Remove
'buffer-switch': no longer used or defined. (Bug#5803)
A long time ago, `read_key_sequence` used to read the keymaps at the
start, so if something happened between this start and the moment
the user actually hits a key, `read_key_sequence` could end up using
the wrong keymaps. To work around this problem, the code used
`record_asynch_buffer_change` to try and trigger `read_key_sequence`
to re-read the keymaps in some known cases.
Several years ago, `read_key_sequence` was changed so as to read the keymaps
only once the user hits a key, making this machinery now redundant
(and also harmful apparently in bug#5803 because it introduces
"spurious" events).
So we here remove `record_asynch_buffer_change` and the
`BUFFER_SWITCH_EVENT` and `Qbuffer_switch` pseudo-events it generated.
* src/termhooks.h (enum event_kind): Delete `BUFFER_SWITCH_EVENT`.
* src/keyboard.c: (record_asynch_buffer_change): Delete function.
(syms_of_keyboard): Delete `Qbuffer_switch`.
(force_auto_save_soon, readable_events)
(kbd_buffer_store_buffered_event, kbd_buffer_get_event)
(make_lispy_event):
* src/xterm.c (handle_one_xevent):
* src/w32term.c (w32_read_socket):
* src/process.c (wait_reading_process_output)
(read_and_dispose_of_process_output, exec_sentinel): Simplify accordingly.
* src/image.c (svg_load): Check `:base-uri' image property to
explicitly set base_uri for images embedded into SVG
(enum svg_keyword_index):
(svg_format): Add :base-uri.
* lisp/svg.el (svg-embed-base-uri-image): New function to embed images
located relative to images `:base-uri'
* lisp/tutorial.el (tutorial--buffer): New variable (bug#27998).
(tutorial--save-on-kill): Use it.
(help-with-tutorial): Set it and add new function to
kill-emacs-query-functions.
* lisp/dired.el (dired--find-file): New function (bug#28949).
(dired-find-file): Use it.
(dired-mouse-find-file): Ditto.
(dired-find-file-other-window): Ditto.
* src/image.c (rsvg_handle_set_dpi_x_y) [WINDOWSNT]: DEF_DLL_FN it.
(init_svg_functions): LOAD_DLL_FN rsvg_handle_set_dpi_x_y.
<rsvg_handle_set_dpi_x_y>: Define as a macro
* doc/lispref/backups.texi (Reverting): Mention markers from
non-file sources (bug#30028).
* lisp/files.el (revert-buffer): Mention what happens with markers
(bug#30028).
* src/fileio.c (Finsert_file_contents): Say a bit more about what
markers are restored (bug#30028).
* src/w32term.c (w32_image_size): New function.
* src/image.c (image_frame_cache_size) [HAVE_NTGUI]: Support
reporting the size of frame image cache.
(image_frame_cache_size, Fimage_cache_size): The total size is
now of the type 'size_t', not 'int'.
* src/nsterm.m (ns_update_end): There's no need to schedule a redraw
if nothing has been changed.
(ns_set_vertical_scroll_bar):
(ns_set_horizontal_scroll_bar): Fix the logic for clearing under the
scrollbars.
(ns_clear_under_internal_border): No need to clip, the default
clipping rectangle will be fine.
* src/image.c (svg_css_length_to_pixels): Pass in a DPI value instead
of using a hard coded value.
(svg_load_image): Set the DPI on the rsvg_handle, and pass it to
svg_css_length_to_pixels.
* lisp/progmodes/cperl-mode.el (cperl-find-pods-heres):
Eliminate conditionals which always evaluate to true if
font-lock is preloaded (since Emacs 22.1). (Bug#45183)
* lisp/gnus/gnus-win.el (gnus-buffer-configuration): Include
shell-command-buffer-name value rather than symbol in pipe
configuration. (Bug#39138, bug#45154)
One search may be applied to several servers: don't let one server's
error derail the whole process.
* lisp/gnus/gnus-search.el (gnus-search-config-error): Define new
error.
(gnus-search-run-search, gnus-search-server-to-engine): Raise this
specific error as appropriate.
(gnus-search-run-query): Catch this error and effectively demote it.
* src/xdisp.c (pos_visible_p): Don't try accessing the glyphs
produced by iterator whose glyph_row was set to NULL; instead,
record the X coordinate before the display string when moving past
it, and use the recorded coordinate if needed. (Bug#45156)
