* src/xterm.c (x_dnd_begin_drag_and_drop): Don't reset
dpyinfo->grabbed when quitting.
(handle_one_xevent): Keep track of dpyinfo->grabbed as well
inside the drag-and-drop event loop.
* src/xterm.c (x_defer_selection_requests)
(x_release_selection_requests): New functions.
(x_dnd_begin_drag_and_drop): Use those functions to defer
selections instead. Fix error signalled when ownership of
XdndSelection is lost.
(handle_one_xevent): Likewise.
* lisp/select.el (x-dnd-targets-list): New defvar.
(xselect-convert-to-targets): Convert XdndSelection based on the
DND targets list.
* src/xfns.c (Fx_begin_drag): Pass new argument.
* src/xselect.c (struct x_selection_request): New struct.
(x_push_current_selection_request):
(x_pop_current_selection_request): New functions.
(x_selection_request_lisp_error, x_reply_selection_request)
(x_handle_selection_request, x_convert_selection)
(syms_of_xselect_for_pdumper): Correctly handle recursive
requests for MULTIPLE by maintaining a stack of selection
requests, converted selections, and other data.
* src/xterm.c (x_dnd_begin_drag_and_drop): New argument
`selection_target_list'. Bind it to the DND targets list.
(syms_of_xterm): New defvar and associated defsym.
* src/xterm.h: Update prototypes.
This fixes errors caused by invalid error traps being left on
the error handler stack if an IO error causes a non-local exit
out of the protected code, and another crash caused by
delete_frame trying to read async input.
* src/eval.c (unwind_to_catch, push_handler_nosignal): Save and
restore the X error handler stack.
* src/lisp.h (struct handler): [HAVE_X_WINDOWS]: New field
`x_error_handler_depth'.
* src/xterm.c (struct x_error_message_stack): Make string a
regular string.
(x_unwind_errors_to): New function.
(x_error_catcher, x_catch_errors_with_handler)
(x_uncatch_errors_after_check, x_uncatch_errors): Update the
stack depth.
(x_check_errors): Stop manually unwinding since unwind_to_catch
now does that for us.
(x_had_errors_p, x_clear_errors): Update for new type of
`string'.
(x_connection_closed): Block input between just before
delete_frame to when the terminal is unlinked.
* src/xterm.h: Update prototypes.
* src/xterm.c (struct x_error_message_stack, x_error_message)
(x_error_catcher, x_catch_errors, x_had_errors_p)
(x_clear_errors): Long-overdue comment update. Describe the
fields of the error message stack, and the fact that
`x_error_message' is a stack, not a pointer to a string (which
has been true since 2006). Also describe the updated conditions
used to find an applicable error handler and to call
x_uncatch_errors_after_check.
* src/xterm.c (handle_one_xevent): Fix _NET_WM_PING cycle again
and set mouse_moved flags during drag-and-drop so reading mouse
events from Lisp continues to work.
* src/xterm.c (x_dnd_begin_drag_and_drop): Set
`x_dnd_recursion_depth'.
(handle_one_xevent): If the recursive edit level is higher than
when DND started, handle mouse events normally.
* src/keyboard.c (prev_kbd_event): Delete function.
(readable_events): Return 1 if
x_detect_pending_selection_requests returns true.
(kbd_buffer_unget_event): Also delete function, since nested
selection requests are really handled correctly.
(kbd_buffer_get_event): Handle events from the special X
deferred selection queue as well.
* src/keyboard.h: Update prototypes.
* src/xselect.c (struct selection_event_queue)
(selection_input_event_equal, x_queue_event)
(x_start_queuing_selection_requests)
(x_stop_queuing_selection_requests): Delete structs, since they
are no longer required.
(x_handle_selection_request, x_handle_selection_event): Allow
nested selection events.
* src/xterm.c (struct x_selection_request_event): New struct.
(x_handle_pending_selection_requests_1)
(x_handle_pending_selection_requests): Handle all events in the
new selection event queue.
(x_push_selection_request, x_detect_pending_selection_requests):
New functions.
(x_dnd_begin_drag_and_drop): Drain the selection queue here as
well.
(handle_one_xevent): When inside a nested event loop, just push
selections to that queue.
(XTread_socket): Allow reading X events if x_dnd_unwind_flag is
true, even though DND is in progress.
(x_delete_display): Delete pending selection events for the
display that is going away.
* src/xterm.h: Update prototypes.
* src/xfns.c (x_frame_list_z_order, Fx_frame_list_z_order): Use
_NET_CLIENT_LIST_STACKING if supported.
* src/xterm.c (x_wm_supports_1): New function. Accept dpyinfo
instead of frame.
(x_wm_supports): Use that function instead.
* src/xterm.h: Update prototypes.

* src/xterm.c (x_tooltip_window_to_frame): New parameter
`unrelated_tooltip_p'.
(XTmouse_position): Pass that, and if it turns out to be true,
look beneath the tooltip window.
* src/xterm.c (x_dnd_get_target_window): Make mapping and
releasing the COW atomic. This is to fix a rare bug when
MPX (multi-pointer X) is in use and the user tries to drag
from both GTK and Emacs at the same time using multiple seats.
* src/nsselect.m (ns_decode_data_to_pasteboard): Convert URL to
path names when we're using NSFilenamesPboardType.
* src/nsterm.m: ([EmacsView performDragOperation:]): Handle
cases where plist is a string.
This has to use a deprecated pasteboard type, since Emacs uses
the "old" (but not deprecated) dragImage: method for
drag-and-drop, which can't drop file URLs.
* lisp/term/ns-win.el (x-begin-drag): Update accordingly.
* src/nsselect.m (ns_decode_data_to_pasteboard):
(Fns_begin_drag): Allow files to be a list of filenames as well.
* src/xterm.c (x_dnd_free_toplevels): Don't leak DND toplevels
if returning a frame.
(x_dnd_begin_drag_and_drop): Make this function reentrant from
the IO error handler.
As suggested by Stefan Monnier.
* src/lread.c (read_escape):
Signal an error for ?\LF since it cannot reasonably be intended.
* test/src/lread-tests.el (lread-escaped-lf): Update test.
* etc/NEWS: Announce.
The previous interface required that users know intricacies of
the data types used to transfer data on each platform Emacs
supports.
* doc/lispref/frames.texi (Drag and Drop): Document new
functions.
* lisp/dired.el (dired-last-dragged-remote-file)
(dired-remove-last-dragged-local-file): Delete functions.
(dired-mouse-drag): Use `dnd-begin-file-drag'.
* lisp/dnd.el (dnd-last-dragged-remote-file)
(dnd-remove-last-dragged-remote-file): New variables and
functions.
(dnd-begin-text-drag, dnd-begin-file-drag): New functions.
* src/xterm.c (x_dnd_begin_drag_and_drop): Add porting note.
* doc/lispref/windows.texi (Window Sizes):
* doc/lispref/display.texi (Size of Displayed Text): Remove
documentation.
* lisp/fringe.el (fringe-mode): Point to the right function.
* lisp/window.el (window-char-pixel-width)
(window-char-pixel-height, window-max-characters-per-line): Remove
functions -- this was already added as window-max-chars-per-line.
* src/window.c (Fwindow_body_width): Adjust doc string.
* src/xterm.c (x_dnd_free_toplevels): New argument
`display_alive'.
(x_dnd_cleanup_drag_and_drop, x_dnd_begin_drag_and_drop)
(handle_one_xevent): Change calls to `x_dnd_free_toplevels'.
(x_connection_closed, x_delete_terminal): Set it to false.
The old -1 value was an artefact of the reader implementation.
* src/lread.c (read_escape): Remove the `stringp` argument; assume
character literal syntax. Never return -1.
(read_string_literal): Handle string-specific escape semantics here
and simplify.
* test/src/lread-tests.el (lread-escaped-lf): New test.
* src/xterm.c (xm_drag_window_error_handler): Store whether or
not an error happened.
(xm_get_drag_window): Handle errors during XCreateWindow and
XChangeProperty without leaking anything.
(x_error_handler): Fix coding style.
* src/dispnew.c (adjust_frame_glyphs_for_frame_redisplay): Make
sure we have valid frame glyph matrices for the interactive
session. (Bug#55760)
(adjust_frame_glyphs): Add assertions for when we fail to allocate
valid frame glyph matrices for a TTY frame.
* src/process.c (syms_of_process): Note max size.
(create_process): Set the pipe size from `read-process-output-max'
(bug#55737).
Copyright-paperwork-exempt: yes
* src/haikuterm.c (haiku_read_socket):
* src/nsterm.m (ns_mouse_position):
* src/xterm.c (XTmouse_position, handle_one_xevent): Apply
special tooltip treatment to `dropping' as well as
`drag-source'.
* src/nsterm.m (ns_mouse_position): Avoid tooltip frames and
look underneath them when `drag-source'.
([EmacsView mouseDown:]):
([EmacsView mouseMoved:]): Ignore events from tip frames.
* src/xterm.c (x_get_window_below): New function.
(XTmouse_position): If track-mouse is drag-source and a window
is a tooltip, look below it.
(handle_one_xevent): Don't generate a nil help-echo event on
LeaveNotify if the display is grabbed and track-mouse is
drag-source.
