Stick an emacs comment directive at the beginning of all the code files so 2006-10-01 Elijah Newren <newren gmail com> * src/*.[ch]: Stick an emacs comment directive at the beginning of all the code files so that people using emacs will be more likely to get coding style correct in their patches. We still need a similar vi directive. #358866

Comprehensively rename to Mutter Code: All references in the code not related to themes, keybindings, or GConf were changed from 'metacity' to 'mutter'. This includes, among other things, strings, comments, the atoms used in the message protocol, and the envvars used for debugging. The GConf schema file was reduced to the 3 settings new to mutter. The overall version was brought up to 2.27 to match current gnome. Structure: All files named '*metacity*' were renamed '*mutter*' with appropriate changes in the automake system. Files removed are doc/creating_themes, src/themes, doc/metacity-theme.dtd, metacity.doap. These files will eventually end up in an external gnome-wm-data module. Installation location: On the filesystem the mutter-plugindir was change from $(libdir)/metacity/plugins/clutter to just $(libdir)/mutter/plugins. The mutter-plugins.pc.in reflects these changes. Note: mutter.desktop.in and mutter-wm.desktop both continue to have X-GNOME-WMSettingsModule=metacity set. This allows gnome-control-center to continue using libmetacity.so for configuration. This is fine since most the general keybindings and wm settings are being read from /apps/metacity/* in gconf.

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()

Add support for stacking X and Wayland windows together This breaks down the assumptions in stack-tracker.c and stack.c that Mutter is only stacking X windows. The stack tracker now tracks windows using a MetaStackWindow structure which is a union with a type member so that X windows can be distinguished from Wayland windows. Some notable changes are: Queued stack tracker operations that affect Wayland windows will not be associated with an X serial number. If an operation only affects a Wayland window and there are no queued stack tracker operations ("unvalidated predictions") then the operation is applied immediately since there is no server involved with changing the stacking for Wayland windows. The stack tracker can no longer respond to X events by turning them into stack operations and discarding the predicted operations made prior to that event because operations based on X events don't know anything about the stacking of Wayland windows. Instead of discarding old predictions the new approach is to trust the predictions but whenever we receive an event from the server that affects stacking we cross-reference with the predicted stack and check for consistency. So e.g. if we have an event that says ADD window A then we apply the predictions (up to the serial for that event) and verify the predicted state includes a window A. Similarly if an event says RAISE_ABOVE(B, C) we can apply the predictions (up to the serial for that event) and verify that window B is above C. If we ever receive spurious stacking events (with a serial older than we would expect) or find an inconsistency (some things aren't possible to predict from the compositor) then we hit a re-synchronization code-path that will query the X server for the full stacking order and then use that stack to walk through our combined stack and force the X windows to match the just queried stack but avoiding disrupting the relative stacking of Wayland windows. This will be relatively expensive but shouldn't be hit for compositor initiated restacking operations where our predictions should be accurate. The code in core/stack.c that deals with synchronizing the window stack with the X server had to be updated quite heavily. In general the patch avoids changing the fundamental approach being used but most of the code did need some amount of re-factoring to consider what re-stacking operations actually involve X or not and when we need to restack X windows we sometimes need to search for a suitable X sibling to restack relative too since the closest siblings may be Wayland windows.

Instead of discarding old predictions the new approach is to trust the predictions but whenever we receive an event from the server that affects stacking we cross-reference with the predicted stack and check for consistency. So e.g. if we have an event that says ADD window A then we apply the predictions (up to the serial for that event) and verify the predicted state includes a window A. Similarly if an event says RAISE_ABOVE(B, C) we can apply the predictions (up to the serial for that event) and verify that window B is above C. If we ever receive spurious stacking events (with a serial older than we would expect) or find an inconsistency (some things aren't possible to predict from the compositor) then we hit a re-synchronization code-path that will query the X server for the full stacking order and then use that stack to walk through our combined stack and force the X windows to match the just queried stack but avoiding disrupting the relative stacking of Wayland windows. This will be relatively expensive but shouldn't be hit for compositor initiated restacking operations where our predictions should be accurate. The code in core/stack.c that deals with synchronizing the window stack with the X server had to be updated quite heavily. In general the patch avoids changing the fundamental approach being used but most of the code did need some amount of re-factoring to consider what re-stacking operations actually involve X or not and when we need to restack X windows we sometimes need to search for a suitable X sibling to restack relative too since the closest siblings may be Wayland windows.

Always map the client and frame windows Traditionally, WMs unmap windows when minimizing them, and map them when restoring them or wanting to show them for other reasons, like upon creation. However, as metacity morphed into mutter, we optionally chose to keep windows mapped for the lifetime of the window under the user option "live-window-previews", which makes the code keep windows mapped so it can show window preview for minimized windows in other places, like Alt-Tab and Expose. I removed this preference two years ago mechanically, by removing all the if statements, but never went through and cleaned up the code so that windows are simply mapped for the lifetime of the window -- the "architecture" of the old code that maps and unmaps on show/hide was still there. Remove this now. The one case we still need to be careful of is shaded windows, in which we do still unmap the client window. In the future, we might want to show previews of shaded windows in the overview and Alt-Tab. In that we'd also keep shaded windows mapped, and could remove all unmap logic, but we'd need a more complex method of showing the shaded titlebar, such as using a different actor. At the same time, simplify the compositor interface by removing meta_compositor_window_[un]mapped API, and instead adding/removing the window on-demand. https://bugzilla.gnome.org/show_bug.cgi?id=720631

Add support for stacking X and Wayland windows together This breaks down the assumptions in stack-tracker.c and stack.c that Mutter is only stacking X windows. The stack tracker now tracks windows using a MetaStackWindow structure which is a union with a type member so that X windows can be distinguished from Wayland windows. Some notable changes are: Queued stack tracker operations that affect Wayland windows will not be associated with an X serial number. If an operation only affects a Wayland window and there are no queued stack tracker operations ("unvalidated predictions") then the operation is applied immediately since there is no server involved with changing the stacking for Wayland windows. The stack tracker can no longer respond to X events by turning them into stack operations and discarding the predicted operations made prior to that event because operations based on X events don't know anything about the stacking of Wayland windows. Instead of discarding old predictions the new approach is to trust the predictions but whenever we receive an event from the server that affects stacking we cross-reference with the predicted stack and check for consistency. So e.g. if we have an event that says ADD window A then we apply the predictions (up to the serial for that event) and verify the predicted state includes a window A. Similarly if an event says RAISE_ABOVE(B, C) we can apply the predictions (up to the serial for that event) and verify that window B is above C. If we ever receive spurious stacking events (with a serial older than we would expect) or find an inconsistency (some things aren't possible to predict from the compositor) then we hit a re-synchronization code-path that will query the X server for the full stacking order and then use that stack to walk through our combined stack and force the X windows to match the just queried stack but avoiding disrupting the relative stacking of Wayland windows. This will be relatively expensive but shouldn't be hit for compositor initiated restacking operations where our predictions should be accurate. The code in core/stack.c that deals with synchronizing the window stack with the X server had to be updated quite heavily. In general the patch avoids changing the fundamental approach being used but most of the code did need some amount of re-factoring to consider what re-stacking operations actually involve X or not and when we need to restack X windows we sometimes need to search for a suitable X sibling to restack relative too since the closest siblings may be Wayland windows.

Split out on_all_workspaces and on_all_workspaces_requested Sometimes on_all_workspaces is requested by the client/user, and sometimes its calculated implicitly due to internal state. We split this up so that we know when the user has explicitly asked for sticky window, when e.g. setting wmspec properties or storing session info. on_all_workspaces means this window is visible on all workspaces. on_all_workspaces_requested, means the user explicitly made the window sticky somehow (via imported session, _NET_WM_STATE from another wm, toggled in the window menu, etc). It always implies on_all_workspaces is TRUE. Right now the only time we set on_all_workspaces is for override-redirect windows, but later we can add a "windows on non-primary monitor are not part of the workspace switching" feature. https://bugzilla.gnome.org/show_bug.cgi?id=609258

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()

Replace public MetaFrameGeometry with MetaFrameBorders There were actually *two* MetaFrameGeometry structs: one in theme-private.h, one in frame.h. The latter public struct was populated by a mix of (void*) casting and int pointers, usually pulling directly from the data in the private struct. Remove the public struct, replace it with MetaFrameBorders and scrap all the pointer hacks to populate it, instead relying on both structs being used in common code. This commit should be relatively straightforward, and it should not do any tricky logic at all, just a sophisticated find and replace. https://bugzilla.gnome.org/show_bug.cgi?id=644930

Simplify the frame testing logic in callers to grab borders A lot of code did something similar to: MetaFrameBorders borders; if (window->frame) meta_frame_calc_borders (window->frame, &borders); else meta_frame_borders_clear (&borders); Sometimes, the else part was omitted and we were unknowingly using uninitalized values for OR windows.

Only shadow ARGB windows with a frame outside the frame An ARGB window with a frame is likely something like a transparent terminal.

Let the UI layer (via the core) construct the frame mask This essentially just moves install_corners() from the compositor, through the core, into the UI layer where it arguably should have been anyway, leaving behind stub functions which call through the various layers. This removes the compositor's special knowledge of how rounded corners work, replacing it with "ask the UI for an alpha mask". The computation of border widths and heights changes a bit, because the width and height used in install_corners() are the meta_window_get_outer_rect() (which includes the visible borders but not the invisible ones), whereas the more readily-available rectangle is the MetaFrame.rect (which includes both). Computing the same width and height as meta_window_get_outer_rect() involves compensating for the invisible borders, but the UI layer is the authority on those anyway, so it seems clearer to have it do the calculations from scratch.
