* src/lread.c (load_path_check): New function, split from init_lread.
(init_lread): Reorganize. Motivation:
If EMACSLOADPATH is set, check/warn about that rather than the
defaults, which we are not going to use. Hence we can remove
the turn_off_warning and WINDOWSNT || HAVE_NS tests.
Don't warn if site-lisp directories are missing.
If not installed, start from a blank load-path, since
PATH_LOADSEARCH refers to the eventual installation directories.
src/xdisp.c (init_iterator): Get dimensions of truncation and
continuation glyphs even if on GUI frames. Adjust
it->last_visible_x on GUI frames when the left or right fringes,
or both, are absent.
(start_display, move_it_in_display_line_to): Handle the case of a
GUI frame without a fringe to display continuation or truncation
glyphs.
(insert_left_trunc_glyphs): Support GUI frames: make sure
truncation glyphs overwrite enough glyphs from the current line to
have sufficient space in pixels.
(display_line): Support truncation and continuation glyphs on GUI
frames. If some spare pixels are left on the line after inserting
the truncation glyphs, fill that space with a stretch glyph of a
suitably computed width.
src/term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
produce_glyphs, to support GUI sessions.
This works better on hosts where time_t is unsigned, and where
float-time is applied to the (negative) difference between two times.
* editfns.c (decode_time_components): Last arg is now double *,
not int *, and means to store all the result as a double, without
worrying about whether the seconds part fits in time_t.
All callers changed.
(lisp_time_argument): Remove last int * arg, as it's no longer needed.
All callers changed.
(Ffloat_time): Do not fail merely because the specified time falls
outside of time_t range.
* configure.in: (getwd): Don't check for it on unixware.
(random, rint): Don't check for these on hpux.
(res_init, libresolv): Don't check for these on darwin.
* src/s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
* src/s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
* src/s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
All Windows-specific code moved to src/s/ms-w32.h.
* src/s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
Windows-specific code from nt/config.nt moved here.
Obsolete settings removed.
(wait_reading_process_output): Don't get the time of day
when gobbling data immediately and not waiting, as there's no need
for it in that case. This removes a FIXME.
* marker.c (byte_char_debug_check): Do not perform the check
if buffer is not multibyte.
(buf_charpos_to_bytepos, buf_bytepos_to_charpos): Call
byte_char_debug_check with correct arguments.
* marker.c (byte_char_debug_check, count_markers): Use
only if ENABLE_CHECKING is defined.
(byte_debug_flag): Remove.
(CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
Always call byte_char_debug_check if ENABLE_CHECKING is defined.
to avoid redundant calls to unchain_overlay.
* buffer.c (drop_overlay): New function.
(delete_all_overlays, Fdelete_overlay): Use it.
* minibuf.c (get_minibuffer): Fix comment.
It has nothing to do with building Emacs, and no-one is likely to be
paying attention to the result. The CANNOT_DUMP branch was pointless,
since it sets EMACSLOADPATH=$(lispsource) it is impossible for there
to ever be any shadows. The EMACSLOADPATH setting was probably necessary
for emacs to work at all when uninstalled, given the way init_lread
works for the CANNOT_DUMP case. Since -batch implies -q, in the
non-CANNOT_DUMP branch, any shadows could only come from site-lisp
files.
src/xdisp.c (display_line): Fix horizontal pixel coordinates when
hscroll is larger than the line width. Fixes long and futile
looping inside extend_face_to_end_of_line (on a TTY) producing
glyphs that are not needed and thrown away.
* gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
not defined (Bug#11768).
(xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
(xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
(make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
followed by gtk_box_set_homogeneous (Bug#11768).
(xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
(update_theme_scrollbar_width, xg_create_scroll_bar): Use
gtk_scrollbar_new (Bug#11768).
(xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
(is_box_type): New function (Bug#11768).
(xg_tool_item_stale_p): Call is_box_type.
(xg_initialize): Get settings by calling gtk_settings_get_for_screen
with default display (Bug#11768).
src/xdisp.c (window_hscroll_limited): New function.
(pos_visible_p, init_iterator): Use it to avoid overflow of pixel
coordinates when window's hscroll is set to insanely large
values.
src/window.h (struct window) <hscroll, min_hscroll>: Change type to 'int'.
This variable's comment says Emacs needs at least one GDB-visible
symbol of type enum pvec_type, to work around GDB problems.
The symbol's value doesn't matter.
* src/lisp.h (enum pvec_type): Use fewer bits.
(PSEUDOVECTOR_SIZE_BITS): New constant.
(PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
(XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
change in pvec_type.
(PSEUDOVECTOR_TYPEP): New macro.
(TYPED_PSEUDOVECTORP): Use it.
* src/fns.c (internal_equal): Adapt code to extract pvectype.
* src/emacs.c (gdb_pvec_type): Update type.
* src/alloc.c (PSEUDOVECTOR_NBYTES): New macro.
(VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
(VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
(SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
(sweep_vectors): Use it. Use local var `total_bytes' instead of
abusing vector->header.next.nbytes.
(live_vector_p): Use PVEC_TYPE.
(mark_object): Adapt code to extract pvectype. Use switch.
optimization level.
* configure.in: If --enable-gcc-warnings, disable
-Wunsafe-loop-optimizations for -O1 optimization level.
* src/doprnt.c (doprnt): Change type of tem to int, initialize
to avoid compiler warning. Add eassert.
* src/search.c (simple_search): Initialize match_byte to avoid
compiler warning. Add eassert.
