* src/xterm.c (x_dnd_begin_drag_and_drop): Select for some
events on the root window.
(x_dnd_update_state): New function.
(handle_one_xevent): Call that function when we get some events
from the root window substructure or the window manager.
(x_term_init): New atom `_NET_CLIENT_LIST_STACKING'.
* src/xterm.h (struct x_display_info): New atom
`_NET_CLIENT_LIST_STACKING'.
* src/bytecode.c (valid_sp): static, not INLINE, as INLINE
should be used only in headers and between INLINE_HEADER_BEGIN
and INLINE_HEADER_END. No need for ‘inline’ here.
* src/alloc.c: Omit unnecessary static function declarations.
Don’t use ‘inline static’ as the C standard says that keyword
order is obsolescent. Anyway, no need for ‘inline’ as compilers
inline without it well enough.
These don’t need to be extern, even with -flto, since
their addresses are taken.
* src/comp.c (helper_unwind_protect, helper_unbind_n)
(helper_save_restriction, helper_GET_SYMBOL_WITH_POSITION)
(helper_PSEUDOVECTOR_TYPEP_XUNTAG): Now static.
* src/comp.c (directory_files_matching) [WINDOWSNT]: New function.
(eln_load_path_final_clean_up) [WINDOWSNT]: Use it.
This removes the need for internal_condition_case_5.
* src/eval.c (internal_condition_case_3)
(internal_condition_case_4, internal_condition_case_5): Remove.
The first two were never used; the last only in now-removed code.
* lisp/emacs-lisp/comp.el (comp-func): Add a command-modes slot.
(comp-spill-lap-function, comp-intern-func-in-ctxt): Fill it.
(comp-emit-for-top-level, comp-emit-lambda-for-top-level): Use it.
* src/alloc.c (mark_object): Mark the command_modes slot.
* src/comp.c (make_subr): Add a command_modes parameter.
(Fcomp__register_lambda): Use it.
(Fcomp__register_subr): Ditto.
* src/data.c (Fcommand_modes): Output the command_modes data for subrs
(bug#54437).
* src/lisp.h (GCALIGNED_STRUCT): Add a command_modes slot.
* src/pdumper.c (dump_subr): Update hash.
(dump_subr): Dump the command_modes slot.
* src/xterm.c (x_dnd_send_enter, x_dnd_send_position)
(xdnd_send_leave, x_dnd_send_drop): Catch errors around call to
XSendEvent. The target window could be gone.
* lisp/erc/erc.el (erc--switch-to-buffer): Commit
f925fc93ba "Add `predicate' arg to
`read-buffer' and use it for erc-iswitchb" meant to remove this, but
it was left behind. (Bug#53617)
Copyright-paperwork-exempt: yes
* src/xdisp.c (prepare_menu_bars): Include in the windows passed
to pre-redisplay-functions windows whose point was moved from the
last recorded position. (Bug#54450)
* src/haiku_support.cc (class EmacsWindow): New field
`window_id'.
(MessageReceived): Ignore dropped messages with same window id.
(be_drag_message): Add source frame's window ID to message.
* configure.ac: Test for the composite extension and use it if
available.
* msdos/sed1v2.inp: Update.
* src/Makefile.in (XCOMPOSITE_LIBS, XCOMPOSITE_CFLAGS): New
variables.
(EMACS_CFLAGS, LIBES): Add new libs and cflags.
* src/xterm.c (x_dnd_get_target_window): Look for proxy on
composite overlay window if mapped.
(x_term_init): Test if the composite extension is available.
* src/xterm.h (struct x_display_info): New fields for composite
extension presence.
* src/xterm.c (x_dnd_begin_drag_and_drop): Clear XIC while event
loop is in progress.
(x_filter_event): Return 0 if DND is in progress.
(xim_instantiate_callback): Likewise.
Functions on `completion-at-point-functions` should not modify
the buffer. Pcomplete itself mostly abides by this but Eshell's
use of it doesn't. Try and catch those cases. Also fix one of
those cases.
* lisp/pcomplete.el (pcomplete-allow-modifications): New var.
(pcomplete-completions-at-point): Enforce it.
(pcomplete, pcomplete-expand-and-complete, pcomplete-expand):
Rebind it since these commands expect the extra side effects.
* lisp/eshell/em-cmpl.el (eshell--pcomplete-insert-tab): New function,
extracted from `eshell-complete-parse-arguments`.
(eshell-complete-parse-arguments): Use it and obey
`pcomplete-allow-modifications`.
Use the new number-to-string code to speed up fixnum printing, with
similar results (often more than twice as fast as before).
* src/data.c (Fnumber_to_string): Move fixnum conversion to...
(fixnum_to_string): ... this new function.
* src/lisp.h: (fixnum_to_string): External declaration.
* src/print.c (print_object): Use fixnum_to_string instead of sprintf.
Do the binary-to-decimal conversion by hand for fixnums instead of
calling sprintf. This results in a noticeable speed increase (on my
machine, 2.2× faster excluding GC).
* src/data.c (Fnumber_to_string): Don't use sprintf for fixnums.
* etc/NEWS: Announce new user option `dired-mouse-drag-files'.
* lisp/dired.el (dired-mouse-drag-files): New user option.
(dired-mouse-drag): New command.
(dired-mouse-drag-files-map): New variable.
(dired-insert-set-properties): Add additional keymap if mouse
dragging is enabled.
* lisp/select.el (xselect-convert-to-targets): Handle new
form of selection converters.
(xselect-convert-to-username):
(xselect-convert-to-text-uri-list):
(xselect-uri-list-available-p): New functions.
(selection-converter-alist): Add them as selection converters.
* src/xselect.c (x_get_local_selection): Handle new form of
selection converters.
(syms_of_xselect): Update doc strings.
