This is a tentative crash fix for a case where there are no enabled weston_outputs at all. Let get_output_work_area() return a zero area if the given output is NULL. If there is no output, there is no area. Unfortunately we cannot return "no position" but have to use 0,0 instead. In send_configure_for_surface(), this causes a maximized surface to receive width=0 and height=0 in the configure event, which means the client is free to choose the size. There is no correct size to send for maximizing for no output. In constrain_position(), this has no effect. The interactive move of a surface is restricted to not go below the panel, so even if a user managed to move a surface without an output, it just prevents the surface moving beyond y=0. In weston_view_set_initial_position(), get_output_work_area() will not be called with NULL output anyway. In set_maximized_position(), this makes it behave as if the output was at 0,0 which is the default position of the first output.

/*
|
||
* Surface stacking and ordering.
|
||
*
|
||
* This is handled using several linked lists of surfaces, organised into
|
||
* ‘layers’. The layers are ordered, and each of the surfaces in one layer are
|
||
* above all of the surfaces in the layer below. The set of layers is static and
|
||
* in the following order (top-most first):
|
||
* • Lock layer (only ever displayed on its own)
|
||
* • Cursor layer
|
||
* • Input panel layer
|
||
* • Fullscreen layer
|
||
* • Panel layer
|
||
* • Workspace layers
|
||
* • Background layer
|
||
*
|
||
* The list of layers may be manipulated to remove whole layers of surfaces from
|
||
* display. For example, when locking the screen, all layers except the lock
|
||
* layer are removed.
|
||
*
|
||
* A surface’s layer is modified on configuring the surface, in
|
||
* set_surface_type() (which is only called when the surface’s type change is
|
||
* _committed_). If a surface’s type changes (e.g. when making a window
|
||
* fullscreen) its layer changes too.
|
||
*
|
||
* In order to allow popup and transient surfaces to be correctly stacked above
|
||
* their parent surfaces, each surface tracks both its parent surface, and a
|
||
* linked list of its children. When a surface’s layer is updated, so are the
|
||
* layers of its children. Note that child surfaces are *not* the same as
|
||
* subsurfaces — child/parent surfaces are purely for maintaining stacking
|
||
* order.
|
||
*
|
||
* The children_link list of siblings of a surface (i.e. those surfaces which
|
||
* have the same parent) only contains weston_surfaces which have a
|
||
* shell_surface. Stacking is not implemented for non-shell_surface
|
||
* weston_surfaces. This means that the following implication does *not* hold:
|
||
* (shsurf->parent != NULL) ⇒ !wl_list_is_empty(shsurf->children_link)
