2.13.2
|
||||
==
|
||||
|
||||
This release just contains a merge of all the changes on the
|
||||
constraints_experiments branch.
|
||||
|
||||
Thanks to Havoc Pennington for reviewing the gargantuan patch and
|
||||
suggesting lots of little fixes for making it better, to Rob Adams and
|
||||
Soeren Sandmann for grilling me on how some of the difficult internals work
|
||||
-- allowing me to improve the documentation, to Olav Vitters for finding an
|
||||
easy-to-fix crasher bug in early testing and for repeatedly extending my
|
||||
deadline for switching from working on Metacity to Bugzilla, to Ray Strode
|
||||
for finding two crashers and fixing one of them in early testing, to Bryan
|
||||
Clark for usability advice, to Davyd Madeley and Christian Kellner for
|
||||
testing Xinerama stuff, to Sebastien Bacher for packaging an early version
|
||||
and finding some obscure bugs (that I unfortunately still can't duplicate
|
||||
and will probably still need to fix once I can),
|
||||
|
||||
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 code 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()
