* font.c, image.c, keyboard.c, lread.c, menu.c, minibuf.c, msdos.c:
* print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
access to `contents' member of Lisp_Vector objects with AREF and ASET
where appropriate.
* subr.el (with-selected-window): Preserve the selected window's
terminal's top-frame.
* window.el (save-selected-window): Likewise.
* frame.c (delete_frame): When selecting a frame on a different
text terminal, do not alter the terminal's top-frame.
* term.c (Ftty_top_frame): New function.
* xdisp.c (format_mode_line_unwind_data): Record the target
frame's selected window and its terminal's top-frame.
(unwind_format_mode_line): Restore them.
(x_consider_frame_title, display_mode_line, Fformat_mode_line):
Callers changed.
(x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
since tty frames can be explicitly named.
(prepare_menu_bars): Likewise.
Fixes: debbugs:4702
* buffer.c (Fkill_buffer): Don't throw an error when the buffer
gets killed during executing of this function (Bug#11665). Try
to always return Qt when the buffer has been actually killed.
(Vkill_buffer_query_functions): In doc-string say that functions
run by this hook should not change the current buffer.
* process.c (write_queue_push, write_queue_pop, send_process):
Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
(write_queue_pop): Fix pointer signedness problem.
(send_process): Remove unused local.
* process.c (make_process): Initialize write_queue.
(write_queue_push, write_queue_pop): New functions.
(send_process): Use them to maintain correct ordering of process writes.
Fixes: debbugs:10815
This removes the need for CHECK.
(CHECK): Remove. Its comments about always evaluating its
argument were confusing, as 'eassert' typically does not evaluate
its argument.
* doc/lispref/display.texi: Document new face attribute.
* lisp/cus-face.el (custom-face-attributes): Add wave-style underline
attribute.
* lisp/faces.el (set-face-attribute): Update docstring.
* src/dispextern.h (face_underline_type): New enum.
(face): Add field for underline type.
* src/nsterm.m (ns_draw_underwave): New function.
(ns_draw_text_decoration): Use it.
* src/w32term.c (w32_restore_glyph_string_clip, w32_draw_underwave):
New functions.
(x_draw_glyph_string): Use them.
* src/xfaces.c (Qline, Qwave): New Lisp objects.
(check_lface_attrs, merge_face_ref)
(Finternal_set_lisp_face_attribute, realize_x_face): Handle
wave-style underline face attributes.
* src/xterm.c (x_draw_underwave): New function.
(x_draw_glyph_string): Use it.
src/xdisp.c (set_cursor_from_row): Don't dereference glyphs_end. If
all the glyphs of the glyph row came from strings, and we have no
cursor positioning clues, put the cursor on the first glyph of the
row.
* lisp.h (USE_2_TAGS_FOR_INTS): Remove, as it was always defined.
(LISP_INT_TAG, case_Lisp_Int, LISP_STRING_TAG, LISP_INT_TAG_P)
(LISP_INT1_TAG, enum Lisp_Type, XINT, XUINT, make_number):
Simplify under the assumption that USE_2_TAGS_FOR_INTS is defined.
(INTTYPEBITS): New macro, for clarity.
(INTMASK, MOST_POSITIVE_FIXNUM): Use it.
(LISP_INT1_TAG, LISP_STRING_TAG, LISP_INT_TAG_P): Simplify
now that USE_LSB_TAG is always defined.
(TYPEMASK, XINT) [USE_LSB_TAG]: Remove unnecessary cast.
(make_number) [!USE_LSB_TAG]: Use INTMASK; that's simpler.
* src/s/usg5-4-common.h, src/s/unixware.h:
Remove define/undef of HAVE_SYSV_SIGPAUSE (not used since 2010-05-04).
* admin/CPP-DEFINES: Remove HAVE_SYSV_SIGPAUSE.
* alloc.c (make_number) [!defined make_number]:
Remove, as lisp.h always defines this now.
(mark_maybe_pointer): Simplify since USE_LSB_TAG is always defined now.
(roundup_size): Verify that it is a power of 2.
* data.c (Fmake_variable_buffer_local, Fmake_local_variable):
* ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO.
* lisp.h (USE_LSB_TAG): Allow the builder to compile with
-DUSE_LSB_TAG=0, to override the automatically-selected default.
USE_LSB_TAG now is always defined to be either 0 or 1.
All uses changed.
(union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
code works fine either way, and efficiency is not a concern here,
as the union type is for debugging, not for production.
(LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
Use an inline function on all platforms when using the union type,
since this is simpler and 'static inline' can be used portably
within Emacs now.
(LISP_INITIALLY_ZERO): New macro.
(XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
(XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.
* configure.in: Check for MagickMergeImageLayers.
* src/image.c (imagemagick_load_image): Use MagickFlattenImage if
MagickMergeImageLayers is undefined. Use pixel pusher loop if
MagickExportImagePixels is undefined.
Fixes: debbugs:11678
* src/alloc.c (make_byte_code): New function.
(Fmake_byte_code): Use it. Don't purify here.
* src/lread.c (read1): Use it as well to avoid extra allocation.
dbus_type_is_basic if available.
(xd_extract_signed, xd_extract_unsigned): Rename from
extract_signed and extract_unsigned, respectively. Adapt callers.
src/dispnew.c (showing_window_margins_p): Undo last change, which
was done due to an inadvertent commit.
(adjust_frame_glyphs_for_frame_redisplay): Do call
showing_window_margins_p.
* lisp/startup.el (argv, argi): Make lexically scoped.
* lisp/emacs-lisp/float-sup.el (pi): Use internal-make-var-non-special.
* lisp/emacs-lisp/cl-macs.el: Use lexical-binding.
Rename cl-bind-* to cl--bind-*.
* lisp/files.el: Don't require `cl' since it doesn't use it.
* lisp/emacs-lisp/pcase.el, lisp/emacs-lisp/macroexp.el: Add coding cookie.
* src/eval.c (Fmake_var_non_special): New primitive.
(syms_of_eval): Defsubr it.
* src/lread.c (syms_of_lread): Mark `values' as lexically scoped.
