screws up AIX.
(struct emacs_tty): Test those symbols, instead of the ioctl
commands.
* sysdep.c (emacs_get_tty, emacs_set_tty, new_ltchars, new_tchars)
(init_sys_modes): Same.

* s/hpux8.h (LIB_X11_LIB, C_SWITCH_SYSTEM, LD_SWITCH_SYSTEM)
(LD_SWITCH_SYSTEM, OLDXMENU_OPTIONS): Add X11R5 directories to the
search paths in these lists; they shouldn't do any harm if they
don't have X11R5.

GCC.
1993-05-26 Richard Stallman (rms@mole.gnu.ai.mit.edu)

redisplay and retry.
(kbd_buffer_get_event): If event is handled here, return nil.
(swallow_events): New function.

* m/symmetry.h (PTY_TTY_NAME_SPRINTF, PTY_NAME_SPRINTF):
Use pty_name, not ptyname.

1993-05-25 Jim Blandy (jimb@wookumz.gnu.ai.mit.edu)
* Version 19.8 released.
1993-05-25 Jim Blandy (jimb@wookumz.gnu.ai.mit.edu)
* xfns.c: Clear out the old face stuff.
(x_face_table, n_faces, x_set_face, x_set_glyph, Fx_set_face_font)
(Fx_set_face, Fx_get_face): Removed.
(syms_of_xfns): Remove defsubr for Fx_set_face.
Arrange for font names to get fully resolved - no wildcards.
* xfns.c (x_set_frame_parameters): Store the value in the frame
parameter alist before we call the setter function, so the setter
function can touch up the value if it chooses.
(x_set_foreground_color, x_set_background_color): Call
recompute_basic_faces, so their GC's will reflect the changes.
(x_new_font): Add extern declaration - this returns a Lisp_Object
now, the fully resolved font name.
(x_set_font): Accept the fully resolved name from x_new_font, and
put it in the frame's parameter alist. Call recompute_basic_faces.
* xterm.c (x_new_font): Return the fully resolved font name, Qnil
(if no match), or Qt (match, but unacceptable metrics).
* xterm.c (x_new_font): Don't call init_frame_faces.
* xterm.h: New section for declarations for xfaces.c.
(init_frame_faces, free_frame_faces, intern_face)
(face_name_id_number, same_size_fonts, recompute_basic_faces)

declaration.
* xfns.c (face_name_id_number): Likewise.
* xterm.c (intern_face): Likewise.
* xterm.c (dumpglyphs): Remember that the default faces can have
null fonts, too.
* xfns.c (Fx_list_fonts): Remember that FACE may not have a font
specified. Don't specify 30000 as the maximum limit on the number
of fonts returned - 2000 is more reasonable.
* xfaces.c (build_face, unload_font, free_frame_faces): Don't
forget to block input while making X calls.
Treat faces as structures specifying modifications to the frame's
parameters, rather than things which need to specify a complete
set of parameters by themselves.
* xfaces.c (init_frame_faces): Don't set up the two frame display
faces by querying the GC - just leave all their fields blank, and
call recompute_basic_faces, letting build_face do the work of
consulting the frame when necessary.
(recompute_basic_faces): New function.
(compute_base_faces): New function for obtaining the "identity"
for compute_char_face and compute_glyph_face.
(compute_char_face, compute_glyph_face): Call it, instead of copying
FRAME_DEFAULT_FACE.
* xfns.c (x_make_gc): No need to call init_frame_faces here.
* xfaces.c (intern_frame_face): This can be static.
* dispextern.h (struct face): New field - `copy', to help us with
resource allocation.
* xfaces.c (free_frame_faces): Do free the first two faces; don't
free anything from a face that's a copy.
(intern_frame_face): Mark every face we intern as a copy; its
resources are actually a combination of the real faces.
(Fset_face_attribute_internal): No need to check if we're trying
to free one of the frame's GC's; they never enter into the
picture.
* casetab.c: Fix formatting, so as not to confuse etags.
* xfns.c (Fx_list_fonts): New function.
(face_name_id_number): Add extern declaration for this.
* xfaces.c (face_name_id_number): Make this externally visible,
and make the FRAME argument a FRAME_PTR, not a Lisp_Object.
(compute_char_face): Call face_name_id_number properly.
* xfaces.c (unload_color): Don't free the pixel for now.
* xfaces.c (merge_faces): You can't tell if a font is a
character-cell font or not by testing whether or not it has a
per_char table. They all do.
* xterm.c (x_new_font): Same deal.
* xfns.c (Fx_list_fonts): Same deal.
* m/iris4d.h: Dyke out the section which specifies how to get the
load average.
* paths.h (PATH_INFO): New path, to edited by the configuration
process.
* callproc.c (Vconfigure_info_directory): New variable, used
internally by build process.
(syms_of_callproc): DEFVAR it and initialize it.
* keyboard.c (Fcurrent_input_mode): Use XFASTINT to build the last
element of the return value, not XSETINT.

Changes for OSF/1:
* mem-limits.h [__osf__ && (__mips || mips)]: #include
<sys/time.h> and <sys/resource.h>.
(get_lim_data): OSF wants a definition like BSD4_2's.
* s/osf1.h: #include "bsd4-3.h", not "s-bsd4-3.h".
* ymakefile (LIBX): Put LD_SWITCH_X_SITE before the libraries, so
it actually has an effect.
Some makes can't handle form feed characters in their makefiles.
* s/usg5-3.h: Remove form feed.
* s/template.h, m/template.h: Remove form feeds.
* xfns.c (select_visual): Include the screen number in the
template of things XGetVisualInfo must match.
1993-05-24 Richard Stallman (rms@mole.gnu.ai.mit.edu)
* s/dgux.h (NO_GET_LOAD_AVG): Test _M88KBCS_TARGET, not __GNUC__.

Convert from parent window, not Emacs window.
(XTread_socket): Handle ReparentNotify events.

(Fmove_overlay): If beg and end are markers, make sure they're in
the right buffer.
1993-05-24 Richard Stallman (rms@mole.gnu.ai.mit.edu)
* keyboard.c (modify_event_symbol): If a name_table elt is null,
generate a name to use. Don't crash.
* fileio.c (Fread_file_name): If input is empty, do return the default
even if !insert_default_directory.
* xterm.c (XTread_socket): For ConfigureNotify event,
translate coordinates if send_event field is false
provided the x-coord value is not large.
1993-05-24 Richard Stallman (rms@mole.gnu.ai.mit.edu)

1993-05-24 Jim Blandy (jimb@wookumz.gnu.ai.mit.edu)
* fileio.c (Ffile_writable_p): Pass XSTRING (foo)->data to
ro_fsys, not XSTRING (foo).
* xterm.c (x_new_font): Reject fonts with varying spacing. We
don't support them yet.
* xfns.c (x_set_font): Report the error message properly.
* xfns.c (Fx_parse_geometry): No need to call check_x here; it
doesn't interact with the server at all, and we need it in order
to create our first frame.
1993-05-24 Richard Stallman (rms@mole.gnu.ai.mit.edu)
* s/linux.h (HAVE_SETSID): Defined.
(HAVE_SOCKETS): Defined.

1993-05-24 Jim Blandy (jimb@wookumz.gnu.ai.mit.edu)
* syssignal.h (sys_signal): Declare the second argument to have
type signal_handler_t. We're told this is necessary for Linux.
1993-05-24 Richard Stallman (rms@mole.gnu.ai.mit.edu)

* xfaces.c (Fset_face_attribute_internal): Don't call unload_font
for the frame's own font.

* m/iris4d.h, m/iris5d.h: Don't use the --cckr CC switch if we're
using GCC.
* m/iris4d.h (NEED_SIOCTL): Move this to...
* s/irix3-3.h (NEED_SIOCTL): ... here; apparently it's not
necessary in irix4-0.h.
* s/irix4-0.h: Remove declaration of getpty; apparently Irix 4.0
already declares this elsewhere.
(PTY_TTY_NAME_SPRINTF): #undef this before re-#defining it.
* m/ibmps2-aix.h, m/pfa50.h, s/hpux.h, s/isc2-2.h, s/linux.h,
* s/sco4.h, s/usg5-4.h: Remove HAVE_RENAME; configure guesses that now.
* config.h.in (LD_SWITCH_X_SITE, C_SWITCH_X_SITE): Change the
#defines to #undef's, so ../configure knows it should tweak them.
* xterm.c (x_scroll_bar_report_motion): Set *TIME whether or not
the mouse is over a scroll bar.
* xfaces.c (Fset_face_attribute_internal): Don't free the frame's
normal_gc or reverse_gc.

motion outside of all windows.
* lisp.h (GLYPH_FACE): Remember that the face portion of a glyph
can be 24 bits, not just eight.
1993-05-23 Richard Stallman (rms@mole.gnu.ai.mit.edu)
* xterm.c: Move signal.h and stdio.h before config.h.
* editfns.c (Fcurrent_time_zone): Assign gmt, instead of init.

* puresize.h [not HAVE_X_WINDOWS] (PURESIZE): Make this 185k,
not 196k. We're actually using ~180k.

changes.
1993-05-22 Richard Stallman (rms@mole.gnu.ai.mit.edu)
* ymakefile (FRAME_SUPPORT): Add mouse.elc, select.elc, scroll-bar.elc.

1993-05-22 Jim Blandy (jimb@geech.gnu.ai.mit.edu)

(read_char): Call it.
(kbd_buffer_store_event): Call it to see if the new character is
the quit or stop character.

1993-05-21 Jim Blandy (jimb@geech.gnu.ai.mit.edu)
* process.c (Fopen_network_stream): Deal with older systems, which
only have the h_addr field in their struct hostent.
* systty.h [SYSV_PTYS]: #include <sys/types.h>. Francesco
Potortì <pot@fly.CNUCE.CNR.IT> says it's necessary on his
machine, and it should be harmless.
1993-05-21 Richard Stallman (rms@mole.gnu.ai.mit.edu)
* sysdep.c (wait_for_termination): Copy code from 18.59
(but sans BSD4_1 alternatives).

xfree on the command line of this compilation.

size argument to bcopy by the size of a glyph.
1993-05-20 Richard Stallman (rms@mole.gnu.ai.mit.edu)
* keyboard.c (read_key_sequence): Reexamine this_command
after pre-command-hook runs.
* xterm.c (x_find_modifier_meanings): If some keys are meta and alt,
make them just meta, not alt.

* config.h.in: Add HAVE_TM_ZONE.
Some more changes from Michael K. Johnson for Linux.
* s/template.h: Mention that you should #define HAVE_TERMIO or
HAVE_TERMIOS, but not both, and that HAVE_TERMIOS is preferred.
* systty.h (EMACS_SET_TTY_PGRP): Don't assign the return value of
tcsetpgrp to *pgid; it's just a status value.
* config.h.in (HAVE_RANDOM): This shouldn't be defined on Linux
systems using XFree386, and perhaps is inappropriate in general.
* m/intel386.h: #undefine the integer size macros, since the Linux
<values.h> file #defines them itself.
* mem-limits.h (get_lim_data): Linux has the ulimit call; if it
fails, fall back on ULIMIT_BREAK_VALUE.
* process.c: Linux needs the WAITTYPE, etc. definitions.
* unexec.c (hdr, ohdr): Linux has the ordinary `struct exec' type;
no need to use SYSV names.
* s/linux.h: New file.
Some changes from Michael K. Johnson for Linux.
* sysdep.c (sys_siglist): Don't define this if HAVE_SYS_SIGLIST is
#defined. That lets the system provide it, if it has it.
* syssignal.h (sigmask): Only define this if <signal.h> hasn't
given us a definition already.
* syssignal.h (sys_sigpause): Fix argument in prototype.
* sysdep.c (init_signals): The masks are called empty_mask and
full_mask, not signal_empty_mask and signal_full_mask.

arguments.

1993-05-19 Jim Blandy (jimb@wookumz.gnu.ai.mit.edu)
* fileio.c (Ffind_file_name_handler): Check that FILENAME is a
string.
* process.c (wait_reading_process_input): Undo change of April
29th, since that re-introduces the race condition the comments are
warning about. Call clear_waiting_for_input before calling
status_notify, though.
* process.c (wait_reading_process_input): Don't forget to call
clear_waiting_for_input when we exit the loop because process
input has arrived.
Changes for Silicon Graphics Iris 5D.
* unexelfsgi.c: New file; like unexelf.c, but tolerates program
segments above BSS.
* m/iris5d.h: New file.
* s/irix5-0.h: New file.
* process.c [__sgi] (allocate_pty): Give up immediately if pty is
inaccessible.

1993-05-18 Jim Blandy (jimb@wookumz.gnu.ai.mit.edu)
* xdisp.c (display_text_line): If the newline (or C-m, in
selective-display) has a non-default face, apply that face to the
remainder of the line, so that the fill occupies the entire line.
* xterm.c (x_new_font): Tell the frame display faces about the
newly chosen font.
Make sure that all the display faces use fonts of the
same dimensions as the default face, so as not to confuse the rest
of the redisplay code.
* xfaces.c (same_size_fonts): New function.
(merge_faces): Only merge in a new font from the FROM face if it
is the same size as the font in the TO face.
* xfns.c (x_set_menu_bar_lines): Minibuffer-only frames can't have
menu bars.
* keyboard.c (read_key_sequence): Don't lay down an unwind_protect
to restore the original buffer until we actually get a mouse click.

* config.h.in (STDC_HEADERS, TIME_WITH_SYS_TIME,
CRAY_STACKSEG_END, STACK_DIRECTION): Add #undef clauses for these,
since otherwise the autoconf tests in configure.in won't do us
much good.
1993-05-16 Richard Stallman (rms@mole.gnu.ai.mit.edu)
* buffer.c (overlays_at): New arg EXTEND.
(Foverlays_at, Fnext_overlay_change): Pass 1.
* xfaces.c (compute_char_face): Pass 0.
Try first with small overlay_vec, then use a big enough one.

knows something has changed.
* xfaces.c (unload_color): Don't try to unload the standard black
or white pixel.
More changes from David Mackenzie.
* ymakefile (emacs): No need to edit srcdir into a lisp file and
then load it; we can just take advantage of the PATH_DUMPLOADSEARCH.
(crt0.o): Remember that crt0.c is in ${srcdir}.
Install David Mackenzie's patches to make ${srcdir} work.
* Makefile.in (srcdir, VPATH): Get this value from the top-level
Makefile.
(xmakefile): Use ${srcdir} to find the files from which we produce
xmakefile. Edit the values for srcdir and VPATH into xmakefile.
* ymakefile (srcdir, VPATH): New definitions for the Makefile
to edit.
(ALL_CFLAGS): Remove `-Is' and `-Im'; add `-I${srcdir}', and
`-I.'.
(emacs): Adjust dumping commands to deal with a separate source
directory.
(${etc}DOC): Pass `-d ${srcdir}' to make-docfile, to tell it where
to find the source files.
(prefix-args): Find the source code in ${srcdir}.
* process.c (wait_reading_process_input): If we're running
Solaris, it's not necessary to check if we should redeliver SIGIO,
according to David Mackenzie.
* s/sol2.h: #include "usg5-4.h", and #define const.
* systime.h: Borrow CPP sequence from getdate.y to include the
proper combination of <time.h> and <sys/time.h>.
1993-05-15 Richard Stallman (rms@mole.gnu.ai.mit.edu)
* window.h (struct window): New slot region_showing.
* xdisp.c (mark_window_display_accurate): Set region_showing fields.
(redisplay_window): Update region_showing field.
(display_text_line): Set region_showing to t if will show one.
* xselect.c (Fx_selection_exists_p): Handle nil, t as SELECTION arg.
Don't die if SELECTION is not recognized.
* dispnew.c (direct_output_forward_char): Just give up
if region is being highlighted.
* xdisp.c (redisplay, redisplay_window): Don't use the cursor-motion
special-case code if the region is or was highlighted.
* xfaces.c (compute_char_face): New args REGION_BEG, REGION_END.
Don't sort if noverlays is 0 or 1.
* dispnew.c (direct_output_for_insert): Pass those args.
* xdisp.c (display_text_line): Pass those args,
describing the region if the mark is transient and active.
1993-05-14 Jim Blandy (jimb@geech.gnu.ai.mit.edu)
* buffer.c (Fmove_overlay): If the overlay is in no buffer and the
BUFFER argument has been omitted, put it in the current buffer,
for symmetry with move-marker.
* buffer.c (Fdelete_overlay): Make the overlay's markers point
nowhere, not at 1. Do this after calling redisplay_region, so
that code knows what section has changed.
1993-05-14 Richard Stallman (rms@mole.gnu.ai.mit.edu)
* xdisp.c (display_menu_bar): Update FRAME_MENU_BAR_ITEMS here.
* keyboard.c (command_loop_1): Don't do it here.
* keymap.c (access_keymap): Handle any length vector.
(store_in_keymap): Likewise.
(Fcopy_keymap): Likewise.
1993-05-14 Jim Blandy (jimb@geech.gnu.ai.mit.edu)
* buffer.c (Foverlay_start, Foverlay_end, Foverlay_buffer)
(Foverlay_properties): Functions moved here from subr.el.
1993-05-13 Jim Blandy (jimb@totoro.cs.oberlin.edu)
* xfaces.c (compute_char_face): When merging the overlays,
traverse sortvec, not overlay_vec; the latter isn't the one we
sorted.
* xterm.c (dumpglyphs): Give the cursor higher priority than the
face specified by the glyph under it.
* xterm.c (dumpglyphs): Move the underline up a row. I dislike
the way X addresses pixels. Quickdraw is much nicer.
* xfaces.c (intern_face): If the face has a GC, but it's not the
default or modeline face, abort. Nothing but those two faces
should have a GC *and* be passed to intern_face.
(compute_char_face, compute_glyph_face): After copying
the frame's default face into face, to use as a base case for
calculation, set the `gc' member to zero; that way we don't have
things lying around that look like display faces but aren't.
* xfaces.c (intern_frame_face): When copying the new face into the
frame's face array, remember that the number of bytes to copy is
sizeof (*new_face), not sizeof (new_face).
* xfaces.c (compute_char_face): Assume that W is displaying the
current buffer. Abort if it isn't.
* lisp.h (Lisp_Overlay): New tag.
(OVERLAYP): New predicate.
(CHECK_OVERLAY): New type-checker.
(Qoverlayp): New extern declaration.
* buffer.c (Foverlayp): New function.
(Qoverlayp): New atom.
(overlays_at, recenter_overlay_lists): Abort if we encounter an
invalid overlay.
(syms_of_buffer): defsubr Soverlayp; initialize Qoverlayp.
(Fdelete_overlay): Set the overlay's markers to point nowhere.
Use CHECK_OVERLAY instead of signalling a special error.
(Fmove_overlay, Foverlay_put): Use CHECK_OVERLAY instead of
signalling a special error.
(Foverlay_get): Use CHECK_OVERLAY.
* fns.c (internal_equal): Define this for overlays.
* buffer.h (OVERLAY_VALID): Define in terms of OVERLAYP.
* print.c (print): Give overlays their own print syntax.
* alloc.c (mark_object): Treat overlays like conses.
* lisp.h (FLOATP): Define this appropriately when LISP_FLOAT_TYPE
is not defined.
* buffer.c (Foverlay_get): Return Qnil if the requested property
is missing from the property list.
The text property routines can now modify buffers other
than the current one.
* insdel.c (modify_region): New argument BUFFER. Select that
buffer while we prepare for the modification, and switch back when
we're done.
* textprop.c (add_properties, remove_properties): Pass
the buffer being modified as the first argument to modify_region.
* editfns.c (Fsubst_char_in_region, Ftranslate_region): Pass the
current_buffer as the first argument to modify_region.
* casefiddle.c (casify_region): Same.
* dispnew.c (direct_output_for_insert): Compute the face of the
character we're inserting properly.
* xterm.c (dumpglyphs): Pass the proper arguments to intern_face.
* xterm.c (dumpglyphs): Don't increment left twice.
* intervals.c (set_point): Check for point out of bounds before
checking for an empty interval tree.
* cmds.c (Fforward_char): Check proposed new position, and then
set point, instead of setting point to a potentially invalid
position.
* lread.c, data.c: If STDC_HEADERS is #defined, include <stdlib.h>
to get the extern declarations for atof. That's where it is in
POSIX.
1993-05-12 Jim Blandy (jimb@geech.gnu.ai.mit.edu)
* ymakefile (xfaces.o): Add window.h to the dependencies.
* xfaces.c (intern_frame_face): Exchange order of arguments, to
make callers correct.
* xfaces.c (compute_char_face): Notice the next property change
location correctly.
* xfaces.c (face_name_id_number): Return 0 (the default face) if
the name is undefined.
* xfaces.c (Fset_face_attribute_internal): Do nothing unless FRAME
is an X frame.
* xdisp.c (copy_rope, copy_part_of_rope): Add face argument.
(display_text_line): Initialize current_face to zero. Apply it
to characters as we write them to the display matrix.
(display_string): Pass the new argument to copy_rope.
* xdisp.c (display_text_line): Handle the locations of face
changes properly.
* textprop.c (Fnext_single_property_change,
Fprevious_single_property_change): Pass arguments to textget in
the right order.
* ymakefile (xfns.o): Remove duplication of buffer.h in dependencies.
* ymakefile ($(OLDXMENU)): Remove extraneous call to `rm'.
1993-05-12 Richard Stallman (rms@mole.gnu.ai.mit.edu)
* keymap.c (Faccessible_keymaps): Use whatever size the vector has.
(Fwhere_is_internal): Likewise.
(describe_vector): Likewise.
(current_minor_maps): Call Findirect_function, so symbols
can be used in place of actual maps.
* xdisp.c (display_text_line): Use break; to exit loop at eol.
Duplicate the short MAKE_GLYPH loop after the main loop.
If no display table, do obey selective_display_ellipses.
(copy_part_of_rope): Arg FROM is now Lisp_Object *.
* xfaces.c: Do include window.h.
(compute_char_face): Supply third arg of Fget_text_property.
* keyboard.c (make_lispy_event): Don't set shift modifier for C-^.
* callproc.c (child_setup): Omit duplicates from new env array.
