Big patch to cover about 6 different issues in order to correct rare 2005-02-20 Elijah Newren <newren@gmail.com> 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 meta_window_ste_user_time() function in order to correct problems

Update constraints code to support the new _NET_WM_STRUT_PARTIAL EWMH 2003-06-10 Rob Adams <robadams@ucla.edu> Update constraints code to support the new _NET_WM_STRUT_PARTIAL EWMH draft specification. See #86682. Also, fix a bug involving work area invalidation on metacity startup. Fix for #108497. Finally, some minor fixes for full screen windows. * src/window.h: Add new MetaStruts structure to store strut rects for a window. Remove has_struts and do_not_cover flag, and support new MetaStruts instead of the four ints. * src/window.c (meta_window_new): change initialization to work with new struts. Also, move meta_window_update_struts call to after the workspaces are initialized to fix #108497. Remove do_not_cover and related code. (process_property_notify): add strut_partial (update_struts): change function name to meta_window_update_struts and expose in external MetaWindow API. Support partial width struts and the new strut rects. * src/workspace.h: add new GSLists containing pointers to all relevant struts for this workspace. * src/workspace.c (meta_workspace_new): initialize the list of strut rects for this workspace. (meta_workspace_free): free the strut rect lists (ensure_work_areas_validated): support new struts and new strut rect lists. Unleash the per-xinerama work areas. * src/constraints.c (get_outermost_onscreen_positions): Use the current window position along with the new per-workspace strut rects to compute the constraints that apply to a particular window. (constraint_hint_applies_func): don't do hints constraints on fullscreen windows (update_position_limits): for maximized windows use the work areas to set the position limits; for other windows rely on the struts constraints to be computed later in get_outermost_onscreen_positions (meta_window_constrain): don't apply aspect ratio hints to full screen windows * src/display.c (meta_display_open): add _NET_WM_STRUT_PARTIAL atom (meta_rectangle_equal): new helper function for MetaRectangles (event_queue_callback): #ifndef out if USE_GDK_DISPLAY not set to avoid compiler warning * src/display.h: add atom_net_wm_strut_partial, and add meta_rectangle_equal. * src/screen.c (meta_screen_rect_intersects_xinerama): change _window_intersects_ to _rect_intersects_ which is more useful now. (meta_screen_resize_func): update struts on windows with struts since struts are relative to the screen size, and this function is called when the screen size updates. * src/screen.h (meta_screen_rect_intersects_xinerama): change _window_intersects_ to _rect_intersects_ which is more useful now. * src/window-props.c (meta_display_init_window_prop_hooks): add hook for strut_partial * src/tools/metacity-window-demo.c: Support partial-width struts on the dock window tests for metacity testing purposes.

Reported by Gregory Merchan and Matthias Clasen. * src/screen.c (startup_sequence_timeout): when timing out a startup sequence, send a remove message, don't just time it out locally.
