* SECTION:pings

* Sometimes we want to see whether a window is responding,

* nominate one function to be called if we get the pong in time and another
* function if we don't. The system is rather more complicated than it needs
* to be, since we only ever use it to destroy windows which are asked to
* close themselves and don't do so within a reasonable amount of time, and
* therefore we always use the same callbacks. It's possible that we might
* use it for other things in future, or on the other hand we might decide

* does or doesn't respond to the ping, we use this information to deal with
* these facts; we have a handler function for each.

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.

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

Merge of all the changes on the constraints_experiments branch. This is 2005-11-18 Elijah Newren <newren@gmail.com> Merge of all the changes on the constraints_experiments branch. This is just a summary, to get the full ChangeLog of those changes (approx. 2000 lines): cvs -q -z3 update -Pd -r constraints_experiments cvs -q -z3 diff -pu -r CONSTRAINTS_EXPERIMENTS_BRANCHPOINT ChangeLog Bugs fixed: unfiled - constraints.c is overly complicated[1] unfiled - constraints.c is not robust when all constraints cannot simultaneously be met (constraints need to be prioritized) unfiled - keep-titlebar-onscreen constraint is decoration unaware (since get_outermost_onscreen_positions() forgets to include decorations) unfiled - keyboard snap-moving and snap-resizing snap to hidden edges 109553 - gravity w/ simultaneous move & resize doesn't work 113601 - maximize vertical and horizontal should toggle and be constrained 122196 - windows show up under vertical panels 122670 - jerky/random resizing of window via keyboard[2] 124582 - keyboard and mouse snap-resizing and snap-moving erroneously moves the window multidimensionally 136307 - don't allow apps to resize themselves off the screen (*cough* filechooser *cough*) 142016, 143784 - windows should not span multiple xineramas unless placed there by the user 143145 - clamp new windows to screensize and force them onscreen, if they'll fit 144126 - Handle pathological strut lists sanely[3] 149867 - fixed aspect ratio windows are difficult to resize[4] 152898 - make screen edges consistent; allow easy slamming of windows into the left, right, and bottom edges of the screen too. 154706 - bouncing weirdness at screen edge with keyboard moving or resizing 156699 - avoid struts when placing windows, if possible (nasty a11y blocker) 302456 - dragging offscreen too restrictive 304857 - wireframe moving off the top of the screen is misleading 308521 - make uni-directional resizing easier with alt-middle-drag and prevent the occasional super annoying resize-the-wrong-side(s) behavior 312007 - snap-resize moves windows with a minimum size constraint 312104 - resizing the top of a window can cause the bottom to grow 319351 - don't instantly snap on mouse-move-snapping, remove braindeadedness of having order of releasing shift and releasing button press matter so much [1] fixed in my opinion, anyway. [2] Actually, it's not totally fixed--it's just annoying instead of almost completely unusable. Matthias had a suggestion that may fix the remainder of the problems (see http://tinyurl.com/bwzuu). [3] This bug was originally about not-quite-so-pathological cases but was left open for the worse cases. The code from the branch handles the remainder of the cases mentioned in this bug. [4] Actually, although it's far better there's still some minor issues left: a slight drift that's only noticeable after lots of resizing, and potential problems with partially onscreen constraints due to not clearing any fixed_directions flags (aspect ratio windows get resized in both directions and thus aren't fixed in one of them) New feature: 81704 - edge resistance for user move and resize operations; in particular 3 different kinds of resistance are implemented: Pixel-Distance: window movement is resisted when it aligns with an edge unless the movement is greater than a threshold number of pixels Timeout: window movement past an edge is prevented until a certain amount of time has elapsed during the operation since the first request to move it past that edge Keyboard-Buildup: when moving or resizing with the keyboard, once a window is aligned with a certain edge it cannot move past until the correct direction has been pressed enough times (e.g. 2 or 3 times) Major changes: - constraints.c has been rewritten; very few lines of code from the old version remain. There is a comment near the top of the function explaining the basics of how the new framework works. A more detailed explanation can be found in doc/how-constraints-works.txt - edge-resistance.[ch] are new files implementing edge-resistance. - boxes.[ch] are new files containing low-level error-prone functions used heavily in constraints.c and edge-resistance.c, among various places throughout the code. testboxes.c contains a thorough testsuite for the boxes.[ch] functions compiled into a program, testboxes. - meta_window_move_resize_internal() *must* be told the gravity of the associated operation (if it's just a move operation, the gravity will be ignored, but for resize and move+resize the correct value is needed) - the craziness of different values that meta_window_move_resize_internal() accepts has been documented in a large comment at the beginning of the function. It may be possible to clean this up some, but until then things will remain as they were before--caller beware. - screen and xinerama usable areas (i.e. places not covered by e.g. panels) are cached in the workspace now, as are the screen and xinerama edges. These get updated with the workarea in src/workspace.c:ensure_work_areas_validated()

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

Merge reduced_resources mode patch from the branch. Offers wireframe and 2003-10-12 Havoc Pennington <hp@redhat.com> Merge reduced_resources mode patch from the branch. Offers wireframe and no-animations. * src/window.c (implement_showing): no animation if we are in reduced resources mode * src/prefs.c: add REDUCED_RESOURCES pref * src/window.c (meta_window_update_keyboard_resize): fix to modify grab_anchor_window_pos to grab_wireframe_rect if appropriate instead of window->rect * src/display.h (struct _MetaDisplay): add grab_start_serial used to avoid responding to events that occurred prior to the grab initialization. Still broken in various ways, specifically EnterNotify that occurred prior to XGrabPointer is processed as if it occurred after. * src/window.c (meta_window_update_keyboard_move): add this instead of meta_window_warp_pointer() crack * src/effects.c (meta_effects_update_wireframe): draw a kind of grid for the wireframe, instead of just a rectangle, like twm * src/screen.c (meta_screen_new): line width of 3 for the XOR gc "Reduced resources" mode based on wireframe patch from Erwann Chenede. Still pretty buggy. * src/keybindings.c (process_keyboard_move_grab) (process_keyboard_resize_grab): add gruesome wireframe hacks * src/display.c (meta_display_end_grab_op): end wireframe (meta_display_begin_grab_op): begin wireframe * src/effects.c (meta_effects_end_wireframe) (meta_effects_update_wireframe, meta_effects_begin_wireframe): routines to draw the wireframe stuff * src/window.c (window_should_be_showing): hide window when doing wireframe, commented out as it breaks grab * src/window.c (meta_window_refresh_resize_popup): handle wireframe * src/screen.c (meta_screen_new): create a screen->root_xor_gc for use in drawing wireframes * src/frames.c (meta_frames_push_delay_exposes): repaint everything before we delay

CVS2003-05-29 Rob Adams <robadams@ucla.edu> CVS2003-05-29 Rob Adams <robadams@ucla.edu> Use a new property _METACITY_SENTINEL to eliminate a race condition that causes focus to behave badly with sloppy/mouse focus when lots of windows are mapped/unmapped, such as with a workspace switch. The EnterNotify events on a display are ignored until the PropertyNotify sent after all the window maps is received. This is a fix for #110970. * src/display.[ch]: New _METACITY_SENTINEL atom. (event_callback): ignore EnterNotify if the sentinel isn't clear, and decrement the sentinel counter when the PropertyNotify is received. (meta_display_increment_focus_sentinel): new function. Increments the sentinel counter and updates the property on a root window on this display. (meta_display_decrement_focus_sentinel): Decrement the sentinel counter. (meta_display_focus_sentinel_clear): returns whether the sentinel counter is zero. * src/window.c (idle_calc_showing): after showing windows, call meta_display_increment_focus_sentinel on each display for windows to be shown. * src/workspace.[ch] (meta_workspace_activate_with_focus): new function activates a workspace and focuses a particular window after the workspace is activated. (meta_workspace_activate): now just a wrapper for meta_workspace_activate_with_focus * src/keybindings.c: use new meta_workspace_activate_with_focus function to ensure that focus will follow the focused window through the workspace switch. : ----------------------------------------------------------------------

Merge of all the changes on the constraints_experiments branch. This is 2005-11-18 Elijah Newren <newren@gmail.com> Merge of all the changes on the constraints_experiments branch. This is just a summary, to get the full ChangeLog of those changes (approx. 2000 lines): cvs -q -z3 update -Pd -r constraints_experiments cvs -q -z3 diff -pu -r CONSTRAINTS_EXPERIMENTS_BRANCHPOINT ChangeLog Bugs fixed: unfiled - constraints.c is overly complicated[1] unfiled - constraints.c is not robust when all constraints cannot simultaneously be met (constraints need to be prioritized) unfiled - keep-titlebar-onscreen constraint is decoration unaware (since get_outermost_onscreen_positions() forgets to include decorations) unfiled - keyboard snap-moving and snap-resizing snap to hidden edges 109553 - gravity w/ simultaneous move & resize doesn't work 113601 - maximize vertical and horizontal should toggle and be constrained 122196 - windows show up under vertical panels 122670 - jerky/random resizing of window via keyboard[2] 124582 - keyboard and mouse snap-resizing and snap-moving erroneously moves the window multidimensionally 136307 - don't allow apps to resize themselves off the screen (*cough* filechooser *cough*) 142016, 143784 - windows should not span multiple xineramas unless placed there by the user 143145 - clamp new windows to screensize and force them onscreen, if they'll fit 144126 - Handle pathological strut lists sanely[3] 149867 - fixed aspect ratio windows are difficult to resize[4] 152898 - make screen edges consistent; allow easy slamming of windows into the left, right, and bottom edges of the screen too. 154706 - bouncing weirdness at screen edge with keyboard moving or resizing 156699 - avoid struts when placing windows, if possible (nasty a11y blocker) 302456 - dragging offscreen too restrictive 304857 - wireframe moving off the top of the screen is misleading 308521 - make uni-directional resizing easier with alt-middle-drag and prevent the occasional super annoying resize-the-wrong-side(s) behavior 312007 - snap-resize moves windows with a minimum size constraint 312104 - resizing the top of a window can cause the bottom to grow 319351 - don't instantly snap on mouse-move-snapping, remove braindeadedness of having order of releasing shift and releasing button press matter so much [1] fixed in my opinion, anyway. [2] Actually, it's not totally fixed--it's just annoying instead of almost completely unusable. Matthias had a suggestion that may fix the remainder of the problems (see http://tinyurl.com/bwzuu). [3] This bug was originally about not-quite-so-pathological cases but was left open for the worse cases. The code from the branch handles the remainder of the cases mentioned in this bug. [4] Actually, although it's far better there's still some minor issues left: a slight drift that's only noticeable after lots of resizing, and potential problems with partially onscreen constraints due to not clearing any fixed_directions flags (aspect ratio windows get resized in both directions and thus aren't fixed in one of them) New feature: 81704 - edge resistance for user move and resize operations; in particular 3 different kinds of resistance are implemented: Pixel-Distance: window movement is resisted when it aligns with an edge unless the movement is greater than a threshold number of pixels Timeout: window movement past an edge is prevented until a certain amount of time has elapsed during the operation since the first request to move it past that edge Keyboard-Buildup: when moving or resizing with the keyboard, once a window is aligned with a certain edge it cannot move past until the correct direction has been pressed enough times (e.g. 2 or 3 times) Major changes: - constraints.c has been rewritten; very few lines of code from the old version remain. There is a comment near the top of the function explaining the basics of how the new framework works. A more detailed explanation can be found in doc/how-constraints-works.txt - edge-resistance.[ch] are new files implementing edge-resistance. - boxes.[ch] are new files containing low-level error-prone functions used heavily in constraints.c and edge-resistance.c, among various places throughout the code. testboxes.c contains a thorough testsuite for the boxes.[ch] functions compiled into a program, testboxes. - meta_window_move_resize_internal() *must* be told the gravity of the associated operation (if it's just a move operation, the gravity will be ignored, but for resize and move+resize the correct value is needed) - the craziness of different values that meta_window_move_resize_internal() accepts has been documented in a large comment at the beginning of the function. It may be possible to clean this up some, but until then things will remain as they were before--caller beware. - screen and xinerama usable areas (i.e. places not covered by e.g. panels) are cached in the workspace now, as are the screen and xinerama edges. These get updated with the workarea in src/workspace.c:ensure_work_areas_validated()

[2] Actually, it's not totally fixed--it's just annoying instead of almost completely unusable. Matthias had a suggestion that may fix the remainder of the problems (see http://tinyurl.com/bwzuu). [3] This bug was originally about not-quite-so-pathological cases but was left open for the worse cases. The code from the branch handles the remainder of the cases mentioned in this bug. [4] Actually, although it's far better there's still some minor issues left: a slight drift that's only noticeable after lots of resizing, and potential problems with partially onscreen constraints due to not clearing any fixed_directions flags (aspect ratio windows get resized in both directions and thus aren't fixed in one of them) New feature: 81704 - edge resistance for user move and resize operations; in particular 3 different kinds of resistance are implemented: Pixel-Distance: window movement is resisted when it aligns with an edge unless the movement is greater than a threshold number of pixels Timeout: window movement past an edge is prevented until a certain amount of time has elapsed during the operation since the first request to move it past that edge Keyboard-Buildup: when moving or resizing with the keyboard, once a window is aligned with a certain edge it cannot move past until the correct direction has been pressed enough times (e.g. 2 or 3 times) Major changes: - constraints.c has been rewritten; very few lines of code from the old version remain. There is a comment near the top of the function explaining the basics of how the new framework works. A more detailed explanation can be found in doc/how-constraints-works.txt - edge-resistance.[ch] are new files implementing edge-resistance. - boxes.[ch] are new files containing low-level error-prone functions used heavily in constraints.c and edge-resistance.c, among various places throughout the code. testboxes.c contains a thorough testsuite for the boxes.[ch] functions compiled into a program, testboxes. - meta_window_move_resize_internal() *must* be told the gravity of the associated operation (if it's just a move operation, the gravity will be ignored, but for resize and move+resize the correct value is needed) - the craziness of different values that meta_window_move_resize_internal() accepts has been documented in a large comment at the beginning of the function. It may be possible to clean this up some, but until then things will remain as they were before--caller beware. - screen and xinerama usable areas (i.e. places not covered by e.g. panels) are cached in the workspace now, as are the screen and xinerama edges.

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.

(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.

CVS2003-05-29 Rob Adams <robadams@ucla.edu> CVS2003-05-29 Rob Adams <robadams@ucla.edu> Use a new property _METACITY_SENTINEL to eliminate a race condition that causes focus to behave badly with sloppy/mouse focus when lots of windows are mapped/unmapped, such as with a workspace switch.
