* src/stack.c (is_focused_foreach, get_standalone_layer): use only
the expected_focus_window instead of both the focused_window and
the expected_focus_window. Removes an infinite flicker loop in

Bug 305564 again.

for whatever reason, at least draw grid frames.
* src/screen.c (meta_screen_new): use fixed alias instead

#123366.

movement.

FIXME in a potentially duplicate section of code,
(meta_workspace_focus_default_window): use the same focus choice

Big patch to cover about 6 different issues in order to correct
rare problems with timestamps (make sure window selected in
tasklist actually gets focus, sanity check timestamps to avoid
rogue apps hosing the system, correct the updating of
net_wm_user_time, correctly handle timestamps of 0 when comparing
xserver timestamps for those who have had their systems up for
over 25 days or so, add some debugging information to verbose
logs, some code cleanups). Fixes all issues listed in #167358.
* src/display.h: (struct _MetaDisplay): clarify comment on
last_focus_time, introduce a new variable--last_user_time,
(XSERVER_TIME_IS_BEFORE macro): put this functionality into a
separate macro and then introduce a new macro with this name that
uses the old one but adds additional special-case checks for
timestamps that are 0, (comment to
meta_display_set_input_focus_window): add information about how
last_user_time should be used in this function
* src/display.c (santiy_check_timestamps): new function,
(meta_display_open): intialize display->last_user_time,
(meta_display_get_current_time_roundtrip): use the timestamp,
which is known to be good, in order to sanity_check_timestamps,
(event_callback): use the new meta_window_ste_user_time() function
in order to correct problems, use the timestamp of KeyPress and
ButtonPress events, which are known to be good, in order to
sanity_check_timestamps, (timestamp_too_old): new function for
common behavior of meta_display_focus_the_no_focus_window and
meta_display_set_input_focus_window, with added checking for
display->last_user_time in addition to display->last_focus_time,
(meta_display_set_input_focus_window): replace some of the code
with a call to timestamp_too_old(),
(meta_display_focus_the_no_focus_window): replace some of th ecode
with a call to timestamp_too_old()
* src/window.h: (meta_window_set_user_time): new function to
abstract the many things that need to be done when updating the
net_wm_user_time of any window
* src/window.c: (meta_window_activate): add debugging spew, make
sure the comparison is made with last_user_time NOT
last_focus_time, use meta_window_set_user_time() function in order
to correct problems, (meta_window_client_message): add a newline
to a debugging message to make them easier to read,
(meta_window_set_user_time): new function
* src/window-props.c (reload_net_wm_user_time): use the new

raise it if possible instead of the window
2005-02-12 Elijah Newren <newren@gmail.com>
Don't unconditionally place splashscreens (and other
not-to-befocused windows) below the focus window. Fixes#167042.
* src/window.c: (intervening_user_event_occurred): new function
taken from the timestamp comparison portion of the old
window_takes_focus_on_map function, (window_state_on_map): new
function with remainder of old window_takes_focus_on_map function
that determines both whether the window will take focus and
whether it should be placed on top, (meta_window_show): use
place_on_top_on_map to determine window stacking instead of trying
to infer it from takes_focus_on_map
2005-02-11 Elijah Newren <newren@gmail.com>
Avoid new windows being obscured by the focus window (and thus
possibly lost). Fixes#166524.
* src/place.c: new MetaWindowDirection enum,
(find_most_freespace): new function to find where there is the
most space available around the focused window,
(meta_window_place): if a window is denied focus and the window

just find the location on the screen with the most space
available.

denied_focus_and_not_transient bitfield
* src/window.c: (meta_window_new_with_attrs): initialize

references to variables and an unnecessary function call to
gdk_window_get_size().

miss any cases. Fixes#166732.

meta_display_get_current_time_roundtrip() to ensure we have a
valid timestamp, (meta_window_unshade): same
* src/display.c: (meta_display_set_input_focus_window): If
CurrentTime was passed, get one from the XServer in addition to
throwing a warning, (meta_display_focus_the_no_focus_window): same
2005-02-08 Elijah Newren <newren@gmail.com>
* src/window.c: (meta_window_activate): If we're not passed a
timestamp, make sure to manually get one. Fixes#166728.

safe to do so. Again, thanks to Crispin Flowerday for the test
case. Thanks to KWin for the inspiration (and to Google for
indexing their source code). Fixes the other half of #166395.
* src/window.c: (meta_window_configure_request): if the
active_window is from a separate application than the one getting
the configure request and the net_wm_user_time of the active
window is later than that of the window getting the configure
request, then ignore the request.
2005-02-06 Elijah Newren <newren@gmail.com>
If activation requests are too old, set the demands_attention hint
instead of actually activating. Thanks to Crispin Flowerday for
the test case and for testing the patch. Fixes half of #166395.

the last focus time, set the demands attention hint instead

reduced_resources' description. Fixes#165780.

focus" that we are now making.

Try 2 to correct misleading and inaccurate wording. Hopefully,
really fixes#165380.
* src/menu.c: Change wording of menu from "Always on Current
Workspace" to "Always on Visible Workspace". "Always on Current
Workspace" could sound like a synonym of "Only on This Workspace"

horizontally for xinerama. Fixes#165261.

Don't wireframe when accessibility is on, it apparently
