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()

Screw around with Anders's ping patch so he'll get plenty of CVS
2002-02-26 Havoc Pennington <hp@pobox.com>
Screw around with Anders's ping patch so he'll get plenty of CVS
conflicts. ;-)
* src/display.c (meta_display_ping_window): spew warnings
if we try to call this with CurrentTime
(meta_display_ping_timeout): remove ping from the pending pings
after it times out.
* src/util.h: added PING debug category
* src/display.c (remove_pending_pings_for_window): don't remove
"tmp" just before "tmp->next", don't break out of loop after
finding the first match
(meta_display_open): no trailing comma in array init
(event_callback): move the processing of ping replies into a
separate function
* src/screen.c (set_supported_hint): add _NET_WM_PING to supported
list
* src/display.h: change gpointer to void*
2002-02-26 Anders Carlsson <andersca@gnu.org>
* src/display.c: (ping_data_free),
(remove_pending_pings_for_window), (meta_display_open),
(event_callback), (meta_display_unregister_x_window),
(meta_display_ping_timeout), (meta_display_ping_window),
(meta_display_window_has_pending_pings):
Implement meta_display_ping_window, and filter out scroll wheel
events.
* src/display.h:
Add MetaWindowPingFunc, meta_display_ping_window and
meta_display_window_has_pending_pings.

Fix bug 143333, support for update counter spec, and 109362, schedule
Sat Jun 19 02:21:08 2004 Soeren Sandmann <sandmann@daimi.au.dk>
Fix bug 143333, support for update counter spec, and 109362,
schedule compensation events when events are ignored.
* src/display.c (meta_display_open): Add _NET_WM_SYNC_REQUEST and
_NET_WM_SYNC_REQUEST_COUNTER atoms. Remove the old
METACITY_SYNC_COUNTER stuff.
(meta_display_begin_op): Setup the sync counter
* src/xprops.c, src/xprops.h, src/window-props.c, src/display.h:
Add new atoms.
* src/window.c (send_sync_request): new function.
(meta_window_move_resize_internal): send a sync request before
resizing.
(check_move_resize_frequence): Rework logic to also check the SYNC
case. If an event is ignored return the remaining time.
(update_resize_timeout): Timeout that gets called when a
compensation event is scheduled.
(uddate_resize): schedule compensation events when an event is
ignored.
(meta_window_handle_mouse_grap_op_event): When an alarm is
received and sync was turned off, turn it back on.
* src/window.h (struct MetaWindow) Add some variables

Add support for _NET_WM_USER_TIME
2004-06-17 Elijah Newren <newren@math.utah.edu>
Add support for _NET_WM_USER_TIME
* src/display.c:
(meta_display_open): Add _NET_WM_USER_TIME to atom_names[],
(event_callback): Manually set _NET_WM_USER_TIME upon KeyPress
(doesn't work since keyboard isn't grabbed) and ButtonPress (does
work), this is just a fallback for applications that don't update
this themselves.
* src/display.h: (struct _MetaDisplay): Add atom_net_wm_user_time field
* src/screen.c: (meta_screen_apply_startup_properties): Check for
TIMESTAMP provided from startup sequence as well.
* src/stack.c:
s/meta_window_set_stack_position/meta_window_set_stack_position_no_sync/,
(meta_window_set_stack_position): New function which calls the
meta_window_set_stack_position_no_sync function followed immediately
by calling meta_stack_sync_to_server.
* src/window-props.c:
(init_net_wm_user_time), (reload_net_wm_user_time): new functions,
(reload_wm_hints): also load atom_net_wm_user_time
* src/window.c:
new XSERVER_TIME_IS_LATER macro (accounts for timestamp wraparound),
(meta_window_new_with_attrs): add timestamp attributes,
(window_takes_focus_on_map): use TIMESTAMP from startup
notification and _NET_WM_USER_TIME to decide whether to focus new
windows,
(meta_window_show): if app doesn't take focus on map, place it
just below the focused window in the stack
(process_property_notify): check for changes to _NET_WM_USRE_TIME,
(meta_window_stack_just_below): new function
* src/window.h:
(_MetaWindow struct): new fields for initial_timestamp,
initial_timestamp_set, net_wm_user_time_set, and net_wm_user_time,
(meta_window_stack_just_below): new function

Fix some support for EWMH hints, and fix USER_TIME support to include the
2004-07-31 Rob Adams <readams@readams.net>
Fix some support for EWMH hints, and fix USER_TIME support to
include the DEMANDS_ATTENTION hint. Also includes some code for
implementing _NET_RESTACK_WINDOW and _NET_MOVERESIZE_WINDOW, but
this is disabled pending feature thaw.
* COMPLIANCE: update with new information
* src/display.c (meta_display_open): add new hints to list
* src/display.h (_MetaDisplay): Add new atoms to struct
* src/screen.c (set_supported_hint): update the list of support
hints.
(set_desktop_viewport_hint): new function sets the viewport hint
to (0,0) as required by the spec for WMs with no viewport support.
(set_desktop_geometry_hint): new function to set the desktop size
hint to the size of the display, since we don't implement large
desktop support, as required by the spec.
(meta_screen_resize): update the geometry hint on screen resize
* src/window.c (meta_window_new_with_attrs): Initialize
demands_attention state
(set_net_wm_state): Set demands_attention hint in the window state
(meta_window_show): If we don't pop up a window because of
USER_TIME, set DEMANDS_ATTENTION on the window.
(meta_window_focus): When a window receives focus, remove
DEMANDS_ATTENTION hint
(meta_window_client_message): Allow other apps to set
DEMANDS_ATTENTION on a window. Also, if the _NET_ACTIVE_WINDOW
hint includes a timestamp, use it.
(update_net_wm_state): Read DEMANDS_ATTENTION state also
* src/window.h (_MetaWindow): add wm_state_demands_attention bit.

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 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()

Fix bug 143333, support for update counter spec, and 109362, schedule
Sat Jun 19 02:21:08 2004 Soeren Sandmann <sandmann@daimi.au.dk>
Fix bug 143333, support for update counter spec, and 109362,
schedule compensation events when events are ignored.
* src/display.c (meta_display_open): Add _NET_WM_SYNC_REQUEST and
_NET_WM_SYNC_REQUEST_COUNTER atoms. Remove the old
METACITY_SYNC_COUNTER stuff.
(meta_display_begin_op): Setup the sync counter
* src/xprops.c, src/xprops.h, src/window-props.c, src/display.h:
Add new atoms.
* src/window.c (send_sync_request): new function.
(meta_window_move_resize_internal): send a sync request before
resizing.
(check_move_resize_frequence): Rework logic to also check the SYNC
case. If an event is ignored return the remaining time.
(update_resize_timeout): Timeout that gets called when a
compensation event is scheduled.
(uddate_resize): schedule compensation events when an event is
ignored.
(meta_window_handle_mouse_grap_op_event): When an alarm is
received and sync was turned off, turn it back on.
* src/window.h (struct MetaWindow) Add some variables

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

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()

Screw around with Anders's ping patch so he'll get plenty of CVS
2002-02-26 Havoc Pennington <hp@pobox.com>
Screw around with Anders's ping patch so he'll get plenty of CVS
conflicts. ;-)
* src/display.c (meta_display_ping_window): spew warnings
if we try to call this with CurrentTime
(meta_display_ping_timeout): remove ping from the pending pings
after it times out.

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
2005-02-20 12:14:16 -05:00
|
|
|
* behavior in this circumstance (so don't do it), (b) it uses
|
|
|
|
|
* display->last_focus_time since we don't have access to the true
|
|
|
|
|
* Xserver one, (c) it makes use of display->user_time since checking
|
|
|
|
|
* whether a window should be allowed to be focused should depend
|
|
|
|
|
* on user_time events (see bug 167358, comment 15 in particular)
