2001-03-14  John Harper  <jsh@eazel.com>

	* version 0.38

2001-03-09  John Harper  <jsh@eazel.com>

	* cursors.c (cursors_init): set default_cursor to Qnil when in
	batch mode (to prevent Fdefault_cursor () returning a null
	value)

2001-03-07  John Harper  <jsh@eazel.com>

	* functions.c (Fx_raise_window, Fx_lower_window): when these
	functions are given a sibling, check if it has been destroyed.
	If so, do nothing to the stacking order

	(This should fix a failed assertion that Ramiro and Duane were
	seeing)

2001-02-26  John Harper  <jsh@eazel.com>

	* keys.c (wm_mod): changed default value from EV_MOD_META to
	ControlMask. Part of my fix to bug 7073

2001-02-19  John Harper  <jsh@eazel.com>

	* version 0.37.3

	* windows.c (install_window_frame, remove_window_frame): only
	do the reparenting if the window hasn't been destroyed

	* stacking-list.c (restack_window): just return immediately if
	the window has already been destroyed

	* stacking-list.c (window_in_stacking_list_p): new predicate,
	used to replace the assert_window_[not_]in_stacking_list
	functions (which have been deleted)

2001-02-18  John Harper  <jsh@eazel.com>

	* functions.c (Frestack_windows, Fx_raise_window,
	Fx_lower_window): be sure to never alter the stacking of
	destroyed windows

	[ I think this should fix the random crashes that some people
	have been experiencing - it was possible for a deleted window
	to be reinserted in the stacking list. Then, when the deleted
	window got garbage collected bogus pointers were left in the
	list.. ]

	* stacking-list.c: added yet more assertions, this time to
	check that destroyed windows aren't being manipulated where
	they shouldn't be

	* sawmill.h (WINDOW_IS_GONE_P): new macro, evaluates to true
	when the window object no longer has an associated client
	window
      	
	* windows.c, frames.c, display.c, keys.c: use the above macro
	instead of `w->id == 0'

2001-02-16  John Harper  <jsh@eazel.com>

	* stacking-list.c (assert_window_in_stacking_list,
	assert_window_not_in_stacking_list): new functions

	* windows.c: use the stacking-list assertions in sensible
	places

2001-02-15  John Harper  <jsh@eazel.com>

	* stacking-list.c: added debugging assertions

2001-02-13  John Harper  <jsh@eazel.com>

	* version 0.37

	* windows.c (remove_window): only call
	remove_from_stacking_list () once per window

2001-02-11  John Harper  <jsh@eazel.com>

	* session.c (save_yourself_2): set outstanding_save_done to
	false after calling SmcSaveYourselfDone ()

2001-02-09  John Harper  <jsh@eazel.com>

	Work to cache the stacking order of windows locally - this
	fixes the bug where reparenting windows screws the stacking
	order and therefore makes the constraint-based stacking code go
	haywire. It's also an efficiency win since we don't need to
	keep asking the server for the order

	* stacking-list.c: new file, code to maintain and manipulate a
	doubly linked list of all managed windows, representing the
	current stacking order. Also has a function to restack a window
	such that it's consistent with its position in the list

	* sawmill.h (Lisp_Window): new fields `above' and `below' -
	linkage for the stacking list

	* functions.c (Frestack_windows, Fx_raise_window,
	Fx_lower_window): these are now implemented in terms of the
	stacking list primitives. The method is simple: get the list
	into the new order, then call restack_window () on any windows
	that changed position in the list

	* windows.c (Fstacking_order): just call make_stacking_list ()

	(add_window, remove_window): add and remove the window from the
	stacking list

	(install_window_frame, remove_window_frame): after calling
	XReparentWindow (), call restack_window () to fix the stacking
	order of the window - this fixes the original bug

2001-02-07  John Harper  <jsh@eazel.com>

	* colors.c (Fget_color): don't try to call XParseColor if we
	have no display connection, just return nil. Patch from merlin
	<merlin@merlin.org

	* fonts.c (x_create_font_set): merged two calls to setlocale ()
	into one. This also avoids problems with its possibly static
	buffer

2001-02-06  John Harper  <jsh@eazel.com>

	* functions.c (functions_init): call XineramaQueryExtension
	before XineramaQueryScreens (in case the extension isn't
	present)

2001-01-28  John Harper  <jsh@eazel.com>

	* session.c (shutdown_cancelled): if we've not already, send a
	SaveYourselfDone message (required by the XSM protocol)

	* main.c (Fexit_type): new function, returns the type of exit
	currently in progress, one of the symbols: `user-quit',
	`user-restart', `session-quit' (or nil if no exit in progress)

	* events.c (save_timestamp): (try to) be more intelligent when
	detecting out of order timestamps. Instead of just discarding
	them, fetch the real time from the X server, then set
	`last_event_time' to the timestamp closest to the current
	server time.

	This avoids sometimes dropping valid timestamps (e.g. after an
	APM resume, focus changes could be lost for a short time)

2001-01-20  John Harper  <jsh@eazel.com>

	* version 0.36

2001-01-18  John Harper  <jsh@eazel.com>

	* windows.c: work around XUrgencyHint only being defined on
	X11R6 and later

2001-01-17  John Harper  <jsh@eazel.com>

	* frames.c (set_frame_shapes): apply the mask of the image
	associated with	the current state of the frame part, not always
	the inactive state

	* frames.c (set_frame_part_bg): if applying a pixmap with no
	mask, set the shape to be the rectangle defined by the edges of
	the frame part. This fixes the bug where parts in which only
	some of the constituent images have alpha channels, get
	corrupted when resized

	* frames.c (configure_frame_part): if the window already
	exists, call XClearArea () to generate an Expose event. This
	fixes the bug where window decorations can update
	inconsistently when resizing windows

2001-01-15  John Harper  <jsh@eazel.com>

	* keys.c (Fbind_keys): signal an error when <1 arg, don't just
	return rep_NULL (which may cause a crash later)

2001-01-09  John Harper  <jsh@eazel.com>

	* windows.c (Fwindow_icon_image): added support for icons
	stored on the KWM_WIN_ICON property (aka `mini icons'). Only
	used when there's no icon in WM_HINTS

	* images.c (Fcrop_image): fix typo when checking validity of
	HEIGHT parameter (patch from martin@whoever.com)

2001-01-05  John Harper  <jsh@eazel.com>

	* version 0.35

2001-01-04  John Harper  <jsh@eazel.com>

	* events.c (map_request): be sure to map the frame (if
	appropriate) _before_ calling the map-notify-hook. Otherwise X
	errors can result from code thinking the frame is visible when
	it isn't yet. Fixes bug 5243 (shaded windows die on restart)

2001-01-02  John Harper  <jsh@eazel.com>

	* images.c (Fcomposite_images): fixed bugs in both gdk-pixbuf
	and Imlib versions

2000-12-30  John Harper  <jsh@eazel.com>

	* gtk-style.c (states): reordered this array so that it matches
	the actual GtkStateType enum. Patch from <michaelj@maine.rr.com>

2000-12-22  John Harper  <jsh@eazel.com>

	* images.c (Fmake_image_from_x_drawable): special cased (=
	depth 1) case for gdk-pixbuf substrate

2000-12-18  John Harper  <jsh@eazel.com>

	* keys.c (direct_modifiers): only substitute physical for
	virtual modifiers if the physical modifiers actually exist.
	Otherwise just preserve the virtual bits

	(translate_event_to_x_button, translate_event_to_x_key): if
	after translating modifiers, any virtual modifiers still exist,
	don't accept the event

	* keys.h (EV_VIRT_MOD_MASK): new definition, the bits
	representing virtual (non X-native) modifiers

2000-12-05  John Harper  <jsh@eazel.com>

	* keys.c (lookup_event): reject events if they're button events
	but don't have at least one button modifier (or the `Any'
	modifier) set. Fixes #4983

2000-12-04  John Harper  <jsh@eazel.com>

	* keys.c: support Button6 and Button7
	* keys.h: define Button6 and Button7 values to their logical
	values (known to work on XFree86 version 4)

	[ adapted from a patch by Steve Haslam <araqnid@debian.org> ]

	* images.c (Fimage_modifier, Fset_image_modifier): fixed bug of
	not accepting () to stand for all three color components

	* version 0.34

2000-11-28  John Harper  <jsh@eazel.com>

	* keys.c (wm_mods, Fwm_modifier, Fset_wm_modifier): a new
	modifier, `W-', that's user-settable
	(Fevent_match): new function for comparing events

	* keys.h (EV_MOD_WM): new bit

2000-11-27  John Harper  <jsh@eazel.com>

	* x.c (x_window_event_handler): ignore any expose events which
	don't have a zero `count' field

2000-11-26  John Harper  <jsh@eazel.com>

	* events.c, functions.c (client_message, Fget_x_property): when
	converting from 32-bit data use rep_make_long_uint () instead
	of rep_MAKE_INT () (which will fail on large values)

2000-11-20  John Harper  <jsh@eazel.com>

	* events.c (focus_out): if unable to find a window, check for a
	deleted window, and nullify focus_window variable if one is
	found

	* windows.c (remove_window): don't nullify focus_window if
	removing the focused window
	(window_mark_type): mark focus_window variable

	* events.c, functions.c, windows.c (Fquery_pointer,
	Fquery_pointer_window, Flist_x_properties, Fget_x_property,
	Fstacking_order): don't call emit_pending_destroys () after
	round trip requests, let them be delivered synchronously

	* events.c: removed all the ignore-fp-keymap stuff

2000-11-18  John Harper  <jsh@eazel.com>

	* x.c (x_window_event_handler): pass the window as the second
	argument to event handlers (event type is the first). Patch
	from Unai Uribarri Rodríguez <unaiur@telecable.es>

2000-11-16  John Harper  <jsh@eazel.com>

	* main.c (sawfish_symbols): defvar `sawfish-locale-directory'
	to the value of the SAWFISH_LOCALEDIR macro

2000-11-14  John Harper  <jsh@eazel.com>

	* windows.c (register_property_monitor, Fwindow_put): a general
	interface for getting notification when the value of a window
	property is changed

	* keys.c (keymap_prop_change): property change handler for
	Qkeymap (used to be embedded into Fwindow_put)

	* events.c (ignore_fp_prop_change): called when the
	ignore-fp-keymap property is changed, if a context map is
	cached, recompute it (really fixes #4708)

	* events.c (current_context_map): cache the context map across
	calls
	(flush_current_context_map): new function

	(button_press, motion_notify): new semantics for context maps
	in motion events, the map is the map that was active when the
	button-press event was received. This fixes the
	fast-window-drag bug #4708

2000-11-13  John Harper  <jsh@eazel.com>

	* version 0.33.1

2000-11-10  John Harper  <jsh@eazel.com>

	* events.c (current_context_map): new function, replaces the
	variable of the same name (the context map may now change
	depending on the environment, so it's not cachable). If the
	window's ignore-fp-keymap property is set, give a null context
	keymap

2000-11-08  John Harper  <jsh@eazel.com>

	* version 0.33

2000-11-07  John Harper  <jsh@eazel.com>

	* frames.c (set_frame_shapes): fix stupid bug of getting
	dimensions of scaled images wrong (introduced by the last
	change)

2000-11-06  John Harper  <jsh@eazel.com>

	* frames.c (apply_mask): local function to clip a mask (if
	required) before union'ing it onto the destination window

	(set_frame_shapes): use apply_mask () to form the image mask,
	otherwise only images whose dimensions are an integer multiple
	of the tiled image can be created without corrupting the
	surrounding state. Fixes #4519

	* pixmap-cache.c: added code to disable the pixmap cache if
	DISABLE_CACHE preprocessor macro is defined

2000-11-02  John Harper  <jsh@eazel.com>

	* events.c (focus_in, focus_out): pass MODE parameter to
	focus-{in,out}-hook as for leave/enter hooks

2000-10-28  John Harper  <jsh@eazel.com>

	* windows.c (window_input_hint_p): new function
	(focus_on_window, Fwindow_wants_input_p): use
	window_input_hint_p. Fixes the bug where window-wants-input-p
	wasn't checking if the InputHint flag was set before reading
	the value

2000-10-24  John Harper  <jsh@eazel.com>

	* events.c: reverted last change (it breaks some focus stuff),
	instead the leave/enter hooks pass an extra argument: MODE, one
	of the symbols `normal', `grab' or `ungrab', the xcrossing.mode
	field of the event

	* events.c: only call leave-notify-hook or enter-notify-hook
	for NotifyNormal events (i.e. ignore Grab/Ungrab events since
	they don't really represent the pointer crossing window
	boundaries)

2000-10-22  John Harper  <jsh@eazel.com>

	* functions.c (Fdisplay_message): new attribute `head . ID'
	specifying the head to centre the message on. Adapted from a
	patch from Geoff Reedy <vader21@imsa.edu>

2000-10-19  John Harper  <jsh@eazel.com>

	* version 0.32

2000-10-18  John Harper  <john@dcs.warwick.ac.uk>

	* events.c (property_notify): track changes to the
	flags.XUrgencyHint field, invoke window-state-change-hook when
	it flips (passing `urgency' state). Also fixed some obscure gc
	protection stuff

	* windows.c (Fwindow_urgent_p): new function

2000-10-09  John Harper  <john@dcs.warwick.ac.uk>

	* keys.c (eval_input_event): only set current_event to null
	when leaving the top-level event loop. This helps when working
	with multiple commands and/or event loops

2000-10-05  John Harper  <john@dcs.warwick.ac.uk>

	* windows.c (Fwindow_wants_input_p): if no WM_HINTS, default to
	false. Also if the window supports WM_TAKE_FOCUS, always return
	true

	(focus_on_window): if sending a WM_TAKE_FOCUS message, only
	explicitly focus on the window if it's accepts-input hint is
	set

2000-09-28  John Harper  <john@dcs.warwick.ac.uk>

	* fake-libexec: patch from John H. Palmieri
	<palmieri@math.washington.edu> to link to libfoo.so as well as
	foo.la (for Tru64?)

2000-09-22  John Harper  <john@dcs.warwick.ac.uk>

	* images.c (images_init): check return value of imlib_init ()
	and bail out if failure

2000-09-20  John Harper  <john@dcs.warwick.ac.uk>

	* version 0.31

2000-09-17  John Harper  <john@dcs.warwick.ac.uk>

	* sawmill.h (Lisp_Window): added bitfield `pending_reshape'

	* frames.c (queue_reshape_frame, commit_queued_reshapes): new
	functions to allow calls to set_frame_shapes () to be buffered

	(set_frame_part_bg): if the background changes, queue a reshape
	of the frame. This removes the long-standing misfeature that
	the different states of each frame part must have the same
	shape

	[ it also means that a lot of needless shaping is happening;
	this could perhaps be reduced by writing a function that just
	calculates the shape of a given sub-region of the frame ]

	* events.c (shape_notify): use queue_reshape_frame () instead
	of set_frame_shapes ()

	* display.c (redisplay): call commit_queued_reshapes ()

	* play-sample.c: exit fn is called rep_dl_kill not rep_dl_exit

2000-09-07  John Harper  <john@dcs.warwick.ac.uk>

	* x.c: make r_fns and x_fns global, and initialize them once
	(non-constant array initializers are a GCC extension)

2000-09-05  John Harper  <john@dcs.warwick.ac.uk>

	* keys.c (lookup_event): when canonifying shifted keysyms,
	don't lose the S- modifier if the shifted and non-shifted
	keysyms are the same (adapted from E. Jay Berkenbilt)

2000-09-04  John Harper  <john@dcs.warwick.ac.uk>

	* images.c (Fcomposite_images): implemented for Imlib

2000-09-03  John Harper  <john@dcs.warwick.ac.uk>

	* keys.c (lookup_event): canonify `S-x' -> `X'

	* x.c, windows.c, session.c, selection.c, main.c, keys.c,
	images.c, functions.c, frames.c, fonts.c, events.c, cursors.c,
	colors.c: magic doc-string comments now include module names

	* images.c (Fmake_sized_image): include an alpha channel when
	using gdk-pixbuf
	(set_pixel): if the image doesn't have an alpha channel, and
	the new value requires it, add it to the image

2000-09-02  John Harper  <john@dcs.warwick.ac.uk>

	* images.c (Fscale_image, Fcomposite_images, Fcrop_image): new
	functions. (composite-image isn't implemented for Imlib yet)

2000-09-01  John Harper  <john@dcs.warwick.ac.uk>

	* sawmill-menu.jl, sawfish-client.jl: moved to ../scripts

	* events.c (record_mouse_position): handle pointer motion
	threshold
	(motion_notify): only evaluate the event if pointer_in_motion
	is true

	* sawmill.h (POS, ABS): new macros

2000-08-31  John Harper  <john@dcs.warwick.ac.uk>

	* keys.c (eval_input_event): removed `yow!' message and
	associated call to Fbeep ()

2000-08-31  John Harper  <john@dcs.warwick.ac.uk>

	* keys.c (window_getting_button_event): new function
	(Fsynthesize_event): for pointer events use
	window_getting_button_event () to locate a suitable window to
	send the event to (one that selects for pointer events)
	(adapted from E. Jay Berkenbilt <ejb@ql.org>, adapted from gwm)

	* functions.c, frames.c, events.c: doc/comment fixes

2000-08-30  John Harper  <john@dcs.warwick.ac.uk>

	* windows.c (Fset_input_focus): treat Qroot arg as Qnil (since
	root-window-keymap is searched when no_focus_window is active)

2000-08-29  John Harper  <john@dcs.warwick.ac.uk>

	* windows.c (add_window): call place-window-hook if
	`initialising' is true; this is the only time that
	place-window-hook is called on a window with the 'placed
	property
	(windows_kill): call remove-window-hook before calling
	remove_window () on each managed window

	* windows.c (emit_pending_destroys): don't decrement
	pending_destroys each iteration, just zero it before exiting

	* windows.c (remove_window): if !destroyed and !from_error,
	reinstall the original border-width of the client window
	(adapted from E. Jay Berkenbilt <ejb@ql.org>)

	* functions.c: if TEST_XINERAMA is defined, fakes a two-headed
	Xinerama config, for testing purposes

2000-08-26  John Harper  <john@dcs.warwick.ac.uk>

	* functions.c (Ffind_head): this was totally broken

2000-08-24  John Harper  <john@dcs.warwick.ac.uk>

	* main.c (inner_main): call rep_top_level_recursive_edit ()
	instead of Frecursive_edit ()

2000-08-21  John Harper  <john@dcs.warwick.ac.uk>

	* x.c: Integrated patch from Ryan Pavlik <rpav@mythosource.org>
	to support a load more GC attributes, plus a new function
	x-gc-set-dashes. Cleaned the whole file to match my usual
	coding style

2000-08-16  John Harper  <john@dcs.warwick.ac.uk>

	* sawmill-menu.jl: use #!optional and #!rest instead of
	deprecated &optional and &rest

2000-08-13  John Harper  <john@dcs.warwick.ac.uk>

	* server.h, libclient.h, libclient.c, client.c: server now
	reliably communicates errors back to the client (as `(signal
	'remote-sawfish (list DATA))' where DATA is a string). Also
	renamed the sockets and X properties. The X protocol now
	includes a version number

2000-08-10  John Harper  <john@dcs.warwick.ac.uk>

	* events.c (configure_request): don't adjust for frame offset
	when marshalling position

2000-08-09  John Harper  <john@dcs.warwick.ac.uk>

	* x.c (create_x_drawable): initialize event_handler field
	(patch from Matt Tucker <tuck@whistlingfish.net>)

2000-07-30  John Harper  <john@dcs.warwick.ac.uk>

	* frames.c (create_window_frame): don't try to reframe windows
	with a non-null list of frame parts, just print an error

2000-07-28  John Harper  <john@dcs.warwick.ac.uk>

	* main.c: changed the usage printing method

2000-07-27  John Harper  <john@dcs.warwick.ac.uk>

	* x.c, windows.c, session.c, selection.c, play-sample.c,
	main.c, keys.c, images.c, gradient.c, functions.c, frames.c,
	fonts.c, flippers.c, events.c, cursors.c, colors.c: split into
	separate sawfish.wm. modules

	* commands.c: deleted, all command handling is written in Lisp

	* fake-libexec: script copied from librep to make symlinked
	plugin tree for when compiling

	* client.c: wrap libclient functions for rep code, installed as
	sawfish.client module

	* sawfish-client.jl: rewrote sawfish-client in Lisp, uses a
	replicated repl to get fully feature front-end in `-' mode

2000-07-25  John Harper  <john@dcs.warwick.ac.uk>

	* sawmill.h: make all bitfields unsigned

2000-07-24  John Harper  <john@dcs.warwick.ac.uk>

	* version 0.30.3

2000-07-23  John Harper  <john@dcs.warwick.ac.uk>

	* sawmill-menu.jl: don't require 'define

2000-07-20  John Harper  <john@dcs.warwick.ac.uk>

	* Makefile.in: avoid warnings from unbuilt dependency files;
	add --mode arguments to libtool commands (from David Kaelbling
	<drk@sgi.com>)

2000-07-17  John Harper  <john@dcs.warwick.ac.uk>

	* frames.c (build_frame_part): if part has 'hidden property
	set, skip this part

2000-07-16  John Harper  <john@dcs.warwick.ac.uk>

	* frames.c (list_frame_generator): when reconfiguring an
	existing frame, adjust its position so that the position of the
	client window in relation to the root window stays constant

2000-07-14  John Harper  <john@dcs.warwick.ac.uk>

	* version 0.30.2

2000-07-13  John Harper  <john@dcs.warwick.ac.uk>

	* x.c, server.c, keys.c, images.c, functions.c, frames.c,
	fonts.c: use global_symbol_value () instead of Fsymbol_value ()
	in places where the symbol is constant, and it may be called
	from gaolled code

2000-07-12  John Harper  <john@dcs.warwick.ac.uk>

	* events.c (configure_request): ensure that one (and only one)
	synthetic ConfigureNotify event is sent to the window after the
	configure request has been handled (even if the window's state
	doesn't change at all)

	[ this fixes the bug where menus in java/swing apps appear too
	high until the window has been moved ]

	* windows.c (manage_windows): if current focus is PointerRoot,

	from Brad Thompson

2000-07-11  John Harper  <john@dcs.warwick.ac.uk>

2000-07-09  John Harper  <john@dcs.warwick.ac.uk>

	* versiom 0.30

2000-07-07  John Harper  <john@dcs.warwick.ac.uk>

	* images.c (get_pixel): don't box the integer twice

	assume full opacity

2000-07-06  John Harper  <john@dcs.warwick.ac.uk>

	* main.c (main): unless XSupportsLocale (), don't use FontSets

	new functions for manipulating image contents

2000-07-02  John Harper  <john@dcs.warwick.ac.uk>

	* version 0.29

	* images.c (Fmake_image_from_x_drawable): combine the grabbed
	image and its mask by hand when using Imlib

2000-06-29  John Harper  <john@dcs.warwick.ac.uk>

	* images.c (Fmake_image_from_x_drawable): fixed memory leak in
	gdk-pixbuf case

	* libclient.c (unix_server_init): removed call to access (),
	rely on connect () failing to tell us when sockets don't exist

2000-06-28  John Harper  <john@dcs.warwick.ac.uk>

	* sawmill-ui.jl, Makefile.in: deleted sawmill-ui.jl

	* keys.c (default_mods): recapitalized the names

	* play-sample.c, fonts.c: use sprintf if no snprintf

2000-06-25  John Harper  <john@dcs.warwick.ac.uk>

	icon, and refresh the frame

2000-06-23  John Harper  <john@dcs.warwick.ac.uk>

	* windows.c (add_window): if `initialising != 0', then set
	`placed' property of window before calling any hooks. This
	stops the window-history module rearranging windows..

	* frames.c (build_frame_part): value of `cursor' attribute will
	be called if it is functionp

	* frames.c (build_frame_part): don't need to check that values

2000-06-21  John Harper  <john@dcs.warwick.ac.uk>

	* fonts.c (generalize_xlfd): don't assume that snprintf (0, ..)

	on Tru64). Patch from Aron Griffis <agriffis@bigfoot.com>

	* pixmap-cache.c (max_cached_pixels): reduced from 256K pixels
	to 64K pixels

2000-06-20  John Harper  <john@dcs.warwick.ac.uk>

	* events.c (configure_request): represent the full complexity
	of the stacking components of the request. The `stack' cell of
	the alist is (RELATION SIBLING), where RELATION is one of the
	symbols `above', `below', `top-if', `bottom-if', `opposite' and
	SIBLING is a window or `nil'

	[ patch from Brad Thompson <yak@mit.edu> ]

	* sawmill.h (Lisp_Window): added `icon_image' field. Null if
	uninitialized, otherwise either Qnil or the image containing
	the window's icon

	* sawmill.h, main.c, keys.c, events.c, commands.c: remove any
	rep-compatibility cruft, we require 0.12 now

2000-06-16  John Harper  <john@dcs.warwick.ac.uk>

	* version 0.28.1

2000-06-14  John Harper  <john@dcs.warwick.ac.uk>

	Work to support non-default visuals and color depths:

	* display.c: support options --visual=TYPE and --depth=DEPTH
	for specifying the preferred visual type and color depth. Also
	removed the screen_{cmap,visual,depth} variables. Replaced by
	preferred_{visual,depth}

	* frames.c: use XCreateWindow instead of XCreateSimpleWindow;
	ensure that we never default to CopyFromParent for any
	parameters (since parent may be different depth/visual)

	* x.c (Fx_create_window): ensure that border_pixel is always
	set to something

	* main.c (usage): updated for new options

	* frames.c, flippers.c, colors.c, images.c, x.c: no longer use

	while testing for directory existance (tarfh may error out)

2000-06-10  John Harper  <john@dcs.warwick.ac.uk>

	* keys.c, keys.h: support `Super' modifier; don't always map
	`Alt' to some modifier, only do this for `Meta' now

2000-06-07  John Harper  <john@dcs.warwick.ac.uk>

	* main.c (sawfish_symbols): moved documentation-file to execdir

	* windows.c (Fwindow_size_hints): do some sanity checking of
	the fields in the size hints structure (e.g. ignore negative
	values)

2000-06-06  John Harper  <john@dcs.warwick.ac.uk>

	* sawmill.h: moved all Imlib code behind `#ifdef IMLIB'
	protection; typedef image_t redirects to image buffer type

	* play-sample.c: only redefine glib macros if glib isn't
	present

	* pixmap-cache.c: new file. Caches image->pixmap mappings. Not
	needed when using Imlib
	* main.c (main): call pixmap_cache_init ()

	characteristics of the visual we'll be using for all drawing

	* functions.c (Fdisplay_message): use image_cmap instead of

	* Makefile.in: added pixmap-cache.c to $(SRCS); use
	$(IMAGE_FOO) instead of $(IMLIB_FOO)

2000-06-05  John Harper  <john@dcs.warwick.ac.uk>

	* main.c, fonts.c: (setq fonts-are-fontsets nil) if setlocale
	() returns null, "C", or "POSIX". This should avoid the problem
	when trying to render 8-bit characters in a 7-bit locale (they
	don't). This is still experimental. Added under guidance from
	Tomohiro KUBOTA

	* windows.c (manage_windows): preserve focus while reparenting
	the windows

	* events.c (focus_in, focus_out): track the window we last
	received focus-in/out on, and only handle the new event if it
	makes a difference (e.g. avoids generating spurious focus-in
	hook calls when keyboard grab is manipulated)

2000-05-31  John Harper  <john@dcs.warwick.ac.uk>

	* fonts.c (generalize_xlfd): don't bother pattern matching
	field contents, just extract by position

2000-05-30  John Harper  <john@dcs.warwick.ac.uk>

	* sawmill-ui.jl (build-symbol): don't use make-closure

	* commands.c (Finteractive): removed, unneeded

	that there is input pending on the display

2000-05-25  John Harper  <john@dcs.warwick.ac.uk>

	* keys.c, commands.c: use rep_call_with_closure () if it's
	available

	* Makefile.in: remove .jlc files in `clean' target, not in
	`realclean'

2000-05-19  John Harper  <john@dcs.warwick.ac.uk>

	* fonts.c: integrated patch from Tomohiro KUBOTA
	<kubota@surfchem0.riken.go.jp> to create FontSets using
	intelligently created font specifications

2000-05-16  John Harper  <john@dcs.warwick.ac.uk>

	* x.c: the old window type can now contain one of three
	different types of drawable: window, pixmap, or bitmap (single
	bitplane pixmap); there's also a function to grab the contents
	of a drawable to an image

	* images.c (Fmake_image_from_x_drawable): new function, the
	guts of Fwindow_icon_image, which now calls this new function

	* sawmill-ui.jl: set the WM_CLASS property on windows

2000-05-15  John Harper  <john@dcs.warwick.ac.uk>

	* frames.c (Qdefault_frame, Qnil_frame): deleted, nil-frame is
	defined in frames.jl, default-frame is never used

2000-05-14  John Harper  <john@dcs.warwick.ac.uk>

	* client.c: new option `-r FEATURE', evaluates `(require 'FEATURE)'

2000-05-12  John Harper  <john@dcs.warwick.ac.uk>

	* events.c (enter_notify): ignore NotifyInferior events
	(entering from inner window), leave_notify has always done this

2000-05-09  John Harper  <john@dcs.warwick.ac.uk>

	* version 0.27

2000-05-08  John Harper  <john@dcs.warwick.ac.uk>

	attribute is ignored

2000-04-15  John Harper  <john@dcs.warwick.ac.uk>

	Fsymbol_value () from the `sawmill' module

2000-04-14  John Harper  <john@dcs.warwick.ac.uk>

2000-03-12  John Harper  <john@dcs.warwick.ac.uk>

	* version 0.25.2

	* x.c: double-buffering now works on all window types, not just
	those created by Fx_create_window ()

2000-03-11  John Harper  <john@dcs.warwick.ac.uk>

	* events.c (handle_input_mask): detect if system clocks is

	the window to raise the first arg immediately above
	(Fx_lower_window): new function, symmetrical to x-raise-window

	unfreeze the intermittent lockups reported by some people

	* keys.c (Qmulti_click_delay): new variable, the maximum delay
	between successive button press events to count as a click2 or
	click3 (from Martin Blais <blais@iro.umontreal.ca>)

	event in one keymap to another keymap (or the name of the
	second keymap). Also, try to detect and avoid situations where

2000-02-28  John Harper  <john@dcs.warwick.ac.uk>

	* gradient.c, flippers.c: don't use rep_dl_subrs or

	* x.c: new plugin (feature `x'), wraps some Xlib functions.
	Allows windows and GCs to be created and drawn with (from

	merlin@merlin.org)

2000-02-26  John Harper  <john@dcs.warwick.ac.uk>

	* windows.c, functions.c, events.c, display.c, commands.c: use
	the non-fixnum number representations where appropriate (where
	32-bit data may be found)

	* sawmill.h, main.c: define rep_INTEGERP (), rep_make_long_uint
	() and rep_get_long_uint () if rep_INTERFACE < 8

2000-02-24  John Harper  <john@dcs.warwick.ac.uk>

	representation

	* frames.c, functions.c: use x_text_width () and x_draw_string ()

2000-02-11  John Harper  <john@dcs.warwick.ac.uk>

	* events.c (configure_request): marshal the event to an alist,
	then call configure-request-hook with it

	exists for the specified keysym (i.e. the keyboard has no such

	This fixes the ``can't bind to -Off events'' bug. Pointed out
	by Matt Krai <krai@ghs.com>

	* keys.c (Fallow_events): if mode is `replay-pointer', then

	working around Imlib's annoying caching

2000-01-07  John Harper  <john@dcs.warwick.ac.uk>

	* sawmill.h: added fps_inactive_highlighted and
	fps_inactive_clicked

	* frames.c (get_pattern_prop): new function, called by
	list_frame_generator to fill the fp->bg, fp->fg and fp->font
	arrays. This now takes a new format, an alist mapping state
	symbols to values (the old formats are also still accepted).
	Current states are `inactive', `focused', `highlighted',
	`clicked', `inactive-focused', `inactive-clicked'. The last two
	are new, there inclusion removes the need for the
	highlight-when-unfocused option, so it's been removed

	* frames.c (mark_frame_type): new function, marks any frame
	parts that are being built but have not yet been added to a
	window

1999-12-24  John Harper  <john@dcs.warwick.ac.uk>

	* functions.c: when reading/writing X properties, use
	u_longs/u_shorts instead of CARD32s/CARD16s; otherwise things

	* session.c (save_yourself): ignore SmSaveGlobal requests

	* events.c (handle_input_mask): don't set last_event_time to

	frame shape from the union of all individual shapes
	(set_frame_part_bg): draw the background manually, instead of
	setting it as the window background and letting the X server do it

	search the root-window-keymap

	* windows.c (before_local_map, after_local_map): new method of
	ignoring locally-generated map/unmap/reparent notify events;
	should remove all race conditions (!). The method is to grab
	the server, unselect the StructureNotifyMask on the window, do
	the request, then reselect events and ungrab

	* windows.c, frames.c: use before_local_map and after_local_map

	* events.c (map_notify, unmap_notify, reparent_notify): removed

	* frames.c: recognize `(below-client . t)' attribute in frame
	part, when set, the part's window is kept _below_ the client

	* windows.c (remove_window): release passive grabs

	* client.c: include readline support from Christopher P Goller
	<goller@eng.utah.edu>

	* version 0.11

	* events.c (focus_in): if focus is passed to the root window,
	focus on our unviewable window

1999-10-04  John Harper  <john@dcs.warwick.ac.uk>

	* functions.c (Fdelete_window): return to using XKillClient

	* keys.c, functions.c: when using the x_win_from_arg function,
	being unable to find a window xid is only an error if we
	weren't passed a window object (gracefully handle windows being
	closed while their handles are in use)

	* sawmill.h (struct frame_part): added a field `drawn'; a
	structure defining the last-drawn contents
	* frames.c: try to optimize frame-part redisplay as much as
	possible, only update fg/bg when they're different to the
	currently displayed data

1999-10-03  John Harper  <john@dcs.warwick.ac.uk>

	* version 0.10

	* windows.c (Fhide_window): if the hidden window has the focus,

	RevertToParent

	* frames.c (reset_frame_parts): redraw any frame parts whose
	state changes

	* events.c (Fcurrent_event_window): moved here from keys.c,
	this now takes an (undocumented) optional argument, the window
	to return for the duration of evaluating this event

	* events.c (reparent_notify): handle case where we're not doing
	the reparenting--unadopt the window and reissue the reparent
	request

1999-10-02  John Harper  <john@dcs.warwick.ac.uk>

	* server.c (server_init): chmod the socket to rwx------

	* frames.c (list_frame_generator): when hide-client is set,
	ensure that the client window ends up unmapped

	* windows.c (focus_on_window): don't focus unmapped client
	windows, focus the frame instead (so its state changes)

	* sawmill.h (Lisp_Window): new bits: `client_hidden' and
	`client_unmapped'. Used to allow the client to be unmapped
	while its shaded. Added integers `local_maps' and
	`local_unmaps': the number of expected notify events

	* events.c (map_notify, unmap_notify): look at the local_maps
	and local_unmaps fields

	* windows.c (Fhide_window, Fshow_window): set the

	that there may be X events read but not handled (Imlib..)

	* libclient.c, libclient.h: abstracted the guts of client.c,
	providing a better interface
	* client.c: call the client_ functions in libclient.o

1999-09-29  John Harper  <john@dcs.warwick.ac.uk>

	* client.c: added back the old unix domain code, if this can't
	make a connection, then try the X property based server

1999-09-28  John Harper  <john@dcs.warwick.ac.uk>

	session management

	* windows.c (Fwindow_wants_input_p): new function, returns the

	* windows.c (remove_window_frame): only remove windows from
	the save-set if the client window was unmapped by its owner

	* display.c (error_handler): ignore errors where resourceid is
	zero, and don't print unrecognized errors, they're just
	annoying..

	* sawmill.h (WINDOWP): now the same as XWINDOWP; i.e. we don't
	care whether or not the client has disappeared (which was
	causing more problems than it solved)

	* windows.c (Fhide_window, Fshow_window): unmap the client
	window when it's hidden (by law of the ICCCM)

	* frames.c (list_frame_generator): raise each frame part
	window as it's created/reconfigured

	* frames.c (set_frame_part_fg, list_frame_generator): the
	`foreground' frame part property may now be an image (or list
	of images), it's drawn into the part, respecting any defined
	justification, but with no scaling or tiling

1999-09-24  John Harper  <john@dcs.warwick.ac.uk>

	* frames.c (set_frame_part_bg): when a shaped image is placed
	(at all) inside the client window, apply the shape mask to the
	frame part's window, not to the frame's window [this may
	conflict with shaped client windows?]

	* images.c (Ftile-image): fix bug when src image is vertically
	smaller than dest image

	* events.c (configure_request): when a client asks to be moved,
	factor in the frame offset if it's reparented

1999-09-23  John Harper  <john@dcs.warwick.ac.uk>

	* keys.c (translate_event): fix bug where X server reports that
	it has a keysym at index 1 as well at index 0, even when
	xmodmap disagrees, and the keysyms are the same (XKB extension
	on XFree86)

	* sawmill-ui.jl (build-keymap): fix cancel/revert problem

	* sawmill-ui.jl (build-keymap): new button: copy

	* sawmill-ui.jl: improved the bindings widget, try to remove
	the annoying jitter when selected list items

	* session.c (Fsm_connect, Fsm_disconnect): new functions.

1999-09-21  John Harper  <john@dcs.warwick.ac.uk>

	* colors.c (Fget_color): allocate all colors using
	Imlib_best_color_match (); this makes no difference using
	TrueColor or DirectColor visuals but should help on PseudoColor
	(i.e. 8 bit) visuals
	* sawmill.h (Lisp_Color): removed the XColor struct, just
	inline the three rgb values and the pixel color

	* main.c (main): call images_init () before colors_init (),
	since colors.c using Imlib

	* images.c, gradient.c, functions.c, frames.c: changes for new
	color type

	* frames.c (list_frame_generator): fix seg fault where either
	Fget_font () or Fget_color () returns an error

	* keys.c (event_proxy_fun): deleted
	(lookup_event_binding): new function, used by eval_input_event

	* version 0.7

1999-09-18  John Harper  <john@dcs.warwick.ac.uk>

	generate the two virtual modifiers

1999-09-17  John Harper  <john@dcs.warwick.ac.uk>

	* frames.c (list_frame_generator): try to prevent weird shaped
	frames being created for very small client windows. The rule is
	that if a frame part's position is specified by a single edge,
	and it overlaps the opposite edge of the client window, then
	truncate the part to that edge. This still isn't perfect, but
	at least the border is always correct

1999-09-16  John Harper  <john@dcs.warwick.ac.uk>

	* keys.c: added Mod5 to list of accepted modifiers

	* events.c (key_press): evaluate KeyRelease events again

	options, control whether we evaluate these abnormal events

	* functions.c (Fwarp_cursor_to_window): unless coordinates are
	given, warp relative to top-left corner of the frame. If coords
	are given, they are relative to the client window

	* functions.c (Fgrab_pointer): accept a nil window, and
	fallback to grabbing on the root if the specified window is
	unviewable

1999-09-15  John Harper  <john@dcs.warwick.ac.uk>

	* frames.c (Qoverride_frame_part_classes): new variable,
	similar to Qframe_part_classes but with higher precedence than
	the frame definition itself

	* session.c, main.c, functions.c, frames.c, commands.c,
	alloca.c: try to support C_ALLOCA and other variants

	* windows.c (emit_pending_destroys): abort if a lisp interrupt
	occurs

	* frames.c (set_frame_part_bg): rearrange how shaped images are
	handled -- it's imperative that the frame must _always_ retain
	the union of the old and new shapes, unfortunately this means
	that we need to make a copy of the original frame shape..

1999-09-14  John Harper  <john@dcs.warwick.ac.uk>

	* commands.c (Fcall_command): changed `f', `w' and `W'
	interactive codes to `%f', `%w' and `%W'. `%' is now reserved

	the position of the message window on the screen

	* windows.c (window_sweep): preserve the order of window_list

	* windows.c (Fwindow_framed_p): new predicate

	* keys.c (translate_event_to_x_button): if no button is
	specified, but mod_any is set, then return AnyModifier and
	Button1 (which should be ignored)
	(grab_event, ungrab_event): support AnyModifier correctly

	* functions.c (Fdelete_window, Fdestroy_window): never use
	XKillClient, just XDestroyWindow

1999-09-12  John Harper  <john@dcs.warwick.ac.uk>

	* version 0.6

	* windows.c (pending_destroys): new variable, the number of
	destroyed windows whose hooks haven't been called
	* windows.c, functions.c, events.c, display.c: call
	emit_pending_destroys () after round-trip X requests, try to
	minimize the time between a window dieing and its
	destroy-notify-hook being called

1999-09-11  John Harper  <john@dcs.warwick.ac.uk>

	* cursors.c (Fcursorp): new function

	* windows.c (set_window_shape): if updating a shaped window
	with no frame, just use a single ShapeSet operation, not a
	ShapeSet followed by a ShapeUnion (fixes the flashing gmc icons
	bug)

1999-09-10  John Harper  <john@dcs.warwick.ac.uk>

	* images.c (Fimagep): new function
	(bevel_pixel): increase the bevel multiplier from 0.5 to 0.75

	* windows.c (window_mark_type): ensure that closed windows
	which haven't had destroy-window-hook called aren't collected

	new window property `removed-parts'
	(get_keymap_for_frame_part): new function

	* events.c (key_press): don't look for a frame part keymap
	(button_press, motion_notify): call get_keymap_for_frame_part

1999-09-09  John Harper  <john@dcs.warwick.ac.uk>

	* keys.c, keys.h: added `click3' event

	* frames.c (frame_part_destroyer): if any of the frame parts
	are clicked, make sure that clicked_frame_part gets cleared

	* frames.c, windows.c: added a new window property
	`hide-client', when non-nil the client window won't be visible
	(call rebuild-frame after setting for it to take effect)

	* keys.c: removed hashed keymaps (vectors), just lists of
	bindings now
	(Fbind_key, Funbind_key): bindings no longer nest

	* sawmill-ui.jl (build-number-entry): use spin-buttons for
	entering numbers

	* events.c (property_notify): fixed this function

1999-09-08  John Harper  <john@dcs.warwick.ac.uk>

	* sawmill.h (Lisp_Window): store window and icon names as lisp
	strings
	* events.c, windows.c: handle lisp string names, fix some
	memory leaks

	* sawmill-ui.jl: added --socket-id option to allow the ui to be
	embedded in the gnome control center. This also disables the
	ok/cancel/etc buttons and enables a hacky protocol on
	stdin/stdout

1999-09-07  John Harper  <john@dcs.warwick.ac.uk>

	* frames.c (destroy_window_frame): new arg, whether or not to
	delete the top-level frame window or not
	(list_frame_generator): handle building a new frame into an old
	top-level window

	* windows.c (Fset_window_frame): don't delete the parent frame
	window, this prevents having to reparent the client back to the
	root, and in turn prevents all flickering

	* sawmill-ui.jl (ui-quit): tell the wm to save the custom file
	before exiting

	* images.c (Ftile_image): new function

	* sawmill-ui.jl: changed the architecture, instead of the wm
	connecting with the configurator, make the configurator connect
	with the wm (using sawmill-client); re-enabled the "revert"
	button

	* sawmill.h (Lisp_Window): added `destroyed' bit
	* windows.c (emit_pending_destroys): call destroy-notify-hook
	where it's required
	* events.c (destroy_notify): only call hook if it's not already
	been called
	(handle_input_mask): call emit_pending_destroys after each event
	* display.c (error_handler): mark that may be input pending on
	the X connection (so that the event loop will call
	emit_pending_destroys)

	* windows.c (install_window_frame, remove_window_frame): handle
	adding and deleting from the save-set here (so that unmapped
	but not destroyed windows are removed from it)

1999-09-06  John Harper  <john@dcs.warwick.ac.uk>

	* sawmill-ui.jl (build-frame-style:update-readme): strip
	trailing whitespace from the README file

	* functions.c (Fshow_message): don't set save_under and
	backing_store in the message window--they slow down opaque
	window movement on XFree86..

	* windows.c, images.c, fonts.c, cursors.c, colors.c: define rep
	comparison functions for these types, I'd forgotten that they
	couldn't just be null pointers

	* display.c (error_handler): don't call destroy-notify-hook
	since it might generate X protocol requests (not allowed)

	* frames.c (Fframe_state_mutex): when this variable is non-nil,
	entering or leaving a frame-part's window won't affect its
	state. As a hack, if you set this to `clicked' the frame part's
	state will be set clicked (this is needed because LeaveNotify

	since active grabs are now synchronous

	* events.c (focus_in): only handle the event if the window is visible

	passes last_event_time)

	* events.c (handle_input_mask): set last_event_time to

	* display.c (XGetAtomNames): implement using XGetAtomName ()
	for X11R5 or less

	* events.c (configure_request): if we know about the window,
	call raise-window or lower-window instead of XRaiseWindow () or

	* display.c (beep): new function, hooked into rep_beep_fun

	current event's window if it's the root

	* client.c: new option `-c COMMAND' to invoke an interactive
	function

	* sawmill-ui.jl (build-pages): use a HPaned widget to contain
	the box and group frame, this stops the boundary changing to
	match their relative sizes

	* version 0.3a

	window to grab in
	(Fungrab_pointer): if we're waiting for a ButtonRelease on a

	object for an id, possibly returning an invalidated object
	(remove_window): even if the window has been invalidated, try
	to remove the frame when appropriate

	* sawmill.h (Lisp_Window): new field `saved_id', this is
	another copy of the window id, but isn't zeroed when the error
	handler finds that the window has been deleted

	* events.c (property_notify): between XGet.. calls, check if
	the error handler invalidated the window

	* events.c (destroy_notify): use the x_find_window_by_id
	function to search for a window object for the destroyed window
	(since the error handler may have invalidated it)

	* keys.c: handle `Alt' similarly to `Meta' (i.e. find the
	actual modifier bit then subsitute it)
	* keys.h: added EV_MOD_ALT

	* events.c (Fquery_pointer): only use the stored mouse position
	if we're currently handling an event, and this event stored the

	frame part
	(lookup_binding): new arg, CURRENT-WINDOW, the window whose
	`keymap' property is to be scanned
	(eval_input_event): if the event is a pointer event, look for a
	binding in the window that received the event, not the window
	with the input focus

	* commands.c (Fcall_command): new interactive specs, `w', the
	window that received the current event, and `W', either the
	same as `w' or the focused window

	* main.c (Qbefore_exit_hook): new hook; called before exiting

	* keys.c (Fcurrent_event_window): as well as returning a window
	object, this might instead return the symbol `root' or the
	integer id of an unmanaged window
	(Fproxy_current_event): send the current event on to a
	specified window

	* gnome.c: deleted, this is now done in lisp

	* functions.c (Fdelete_window): accept integer window ids

	* client.c (eval_lisp_form): don't use puts () to output the
	result string since it could contain zero bytes

	* windows.c (remove_window): a new argument FROM-ERROR. If
	non-nil then we're being called from the error handler, and
	thus won't generate any X protocol requests, let gc destroy the
	frame later

	* frames.c (frame_part_destroyer): don't try to delete parts
	without windows

1999-08-19  John Harper  <john@dcs.warwick.ac.uk>

	* frames.c, events.c: it's possible for Imlib_render to trigger
	the X error handler, and possibly invalidate the window that's

	positions, the new function Fquery_last_pointer allows access
	to the earlier position

1999-08-11  John Harper  <john@dcs.warwick.ac.uk>

	* sawmill-ui.jl: use a ButtonBox for the control buttons, don't

	* windows.c (fix_window_size): call set_window_shape

	* windows.c (add_window): set frame_style to nil not
	default-frame initially
