* src/haiku_support.cc (movement_locker): New locker.
(MouseMoved): Lock that locker.
(BWindow_new):
(BWindow_quit): Use LockLooper instead of Lock.
* src/haikuterm.c (haiku_read_socket): Clear mouse face if
a motion event is received for a frame other than the one
that is currently displaying the mouse face.
* src/haiku_support.cc (EmacsShow): Fix last change.
(TearDownDoubleBuffering): Likewise.
(Draw): Draw normally if not double buffered even if shown_flag
is true.
* src/haiku_draw_support.cc (BView_DrawBitmapWithEraseOp):
(BView_DrawMask):
(BBitmap_transform_bitmap):
* src/haiku_support.cc (AttachCairoSurface): Adjust calculations
to take account of BRect width and height functions returning
(start - end) instead of the actual width and height of the
rectangle.
* src/haiku_support.cc (class EmacsWindow): New field
`was_shown_p'.
(EmacsShow): Lock looper if the window wasn't ever visible.
(BWindow_new): Unlock window looper after creating it.
* src/haiku_support.cc (~EmacsWindow):
(UpwardsSubsetChildren):
(UpwardsUnSubsetChildren): Fix locking semantics.
* src/haikuterm.c (haiku_read_socket): Flush dirty back buffers
after clearing mouse face because the pointer was moved out of a
frame.
* src/haiku_support.h: (BWindow_sync)
* src/haiku_support.cc (BWindow_sync): New function.
* src/haikuterm.c (haiku_frame_raise_lower): Synchronize window
after raising it to avoid situations where raising windows is
done out-of-order, such as when ediff raises a frame.
Each BWindows (and various system callbacks) runs in a separate
thread, so there are very complicated locking semantics that
used to be handled manually. This changes child frame state to
use a single global lock, which makes things much easier.
* src/haiku_support.cc (child_frame_lock): New variable.
(class EmacsWindow):
(~EmacsWindow):
(Unparent):
(ParentTo):
(MoveChild):
(FrameMoved):
(EmacsHide):
(EmacsShow):
(GetParentWidthHeight):
(OffsetChildRect):
(MakeFullscreen):
(SetUpDoubleBuffering): Use a single lock for controlling access
to child frame state.
The direct rendering code used in that situation never
completely worked, and the BDirectWindow destructor is also
buggy. Completely remove that code in order to let us inherit
from BWindow, so as to prevent the buggy destructor from being
run.
* src/haiku_support.cc (cairo_format_from_color_space): Delete
function.
(class EmacsWindow): Inherit from BWindow.
(EmacsWindow): Call BWindow constructor instead.
(MessageReceived):
(DispatchMessage):
(FrameResized):
(FrameMoved):
(Zoom): Call BWindow functions instead.
(EmacsView_cairo_surface): Stop looking for surfaces in the
window.
(EmacsWindow_begin_cr_critical_section):
(EmacsWindow_end_cr_critical_section): Stop locking the window.
* src/haikufns.c (haiku_set_inhibit_double_buffering): Always
enable double buffering on Cairo builds.
Since the location of those files changes between build time and
installation time, this requires to tweak the file name used in those
(#$ . NNN) references during the dump so they don't hardcode the build
directory. We do it in the same way as was already done for those
same file names in `load-history`, except we convert them back to
absolute file names more lazily (i.e. when fetching the actual
docstring rather than at startup), which requires remembering the
`lisp-dir` computed at startup in the new `lisp-directory` variable.
* src/Makefile.in ($(etc)/DOC): Don't scan Lisp files any more.
* src/lread.c (Fload): Use relative file names for `load-file-name`
when preloading for the dump, like we already did for `current-load-list`.
(read_list): Don't zero-out dynamic docstring references during the
preload since they won't be filled later by Snarf-documentation any more.
(read1): Remove the hash-hack for doc references that were zeroed.
* lisp/startup.el (lisp-directory): New variable.
(command-line): Set it.
* src/doc.c (get_doc_string): Use `lisp-directory` for dynamic
docstring references using relative file names.
(syms_of_doc): Add `Qlisp_directory`.
* lib-src/make-docfile.c (scan_file): Don't handle `.el` or `.elc`
files any more.
(IS_SLASH): Remove macro, not used any more.
(skip_white, read_lisp_symbol, search_lisp_doc_at_eol)
(scan_lisp_file): Remove functions, not used any more.
* doc/lispref/loading.texi (Library Search): Mention `lisp-directory`.
* src/xterm.c (handle_one_xevent): Pass through pinch events to
xwidgets and provide root coordinates when translating motion
events.
* src/xwidget.c (xwidget_motion_notify): Use provided root
window coordinates.
(xwidget_pinch): New function.
* src/xwidget.h (xwidget_motion_notify): Update prototype.
(xwidget_pinch): New function prototype.
* src/xwidget.c (Fxwidget_perform_lispy_event): Restore original
embedder after performing event.
(Fdelete_xwidget_view): Block input around non-reentrant
section.
* src/font.c (font_score, font_delete_unmatched): Don't assume
weight, slant, and width properties of the font must be fixnums:
some variable-weight fonts violate that assumption. Reported
by Sean Whitton <spwhitton@spwhitton.name>. Do not merge to
master. (Bug#52888)
* src/xdisp.c (pop_it): Recompute the 'start_of_box_run_p' flag,
like we do in 'handle_fontified_prop', when faces change while
iterating over a buffer or string. (Bug#51550)
* lisp/xwidget.el (xwidget-info): New function declaration.
(xwidget-webkit-scroll-forward):
(xwidget-webkit-scroll-backward): Hscroll the window if the
widget is wider than the text area. (bug#52885)
* src/xwidget.c (xwidget_scroll, xwidget_motion_notify): Apply
clip offsets to coordinates.
* src/xfns.c (x_get_monitor_attributes_xrandr): Use XRR 1.5 if
present.
(xlw_monitor_dimensions_at_pos_1): Remove redundant XRR 1.5
code.
(xlw_monitor_dimensions_at_pos): Rely on
`x_get_monitor_attributes_xrandr' to retrieve the workarea
instead.
* src/xwidget.c (xi_translate_notify_detail): New function.
(xwidget_motion_or_crossing): Translate detail and state of
GenericEvents before sending them to the widget.
* src/xfns.c (Fx_backspace_delete_keys_p): Use
dpyinfo->supports_xkb instead of testing for its presence
manually.
* src/xterm.c (x_term_init): Test for Xkb presence
and set supports_xkb appropriately.
* src/xterm.h (struct x_display_info): New field `supports_xkb'.
* src/xterm.c (handle_one_xevent): Pass XI2 entry and leave
events to xwidgets and fix scroll valuator reset logic for
xwidgets.
* src/xwidget.c (xwidget_button_1): Stop ungrabbing all devices
XI2 builds.
(xwidget_motion_or_crossing): Learn to pass through XI2 crossing
events.
(x_draw_xwidget_glyph_string): Add crossing events to the XI2
event mask.
