Ignoring the focus leads to a broken focus if the pointer is, e.g.,
over i3bar at the point in time the window is moved by the client
message. It also causes i3bar's workspace display to break.
Thanks to GermainZ for reporting.
We already claim _NET_WM_DESKTOP support in _NET_SUPPORTED since around 2009,
but haven't actually done anything with it. However, especially pagers like
gnome-panel rely on this property to be updated and many tools, like GTK, want
to use the corresponding client messages to make a window sticky, move it
around etc.
This patch implements full support according to the EWMH spec. This means:
* We set the property on all windows when managing it.
* We keep the property updated on all windows at all times.
* We read and respect the property upon managing a window if it was set before
mapping the window.
* We react to client messages for it.
* We remove the property on withdrawn windows.
Note that the special value 0xFFFFFFFF, according to the spec, means that the
window shall be shown on all workspaces. We do this by making it sticky and
float it. This shows it on all workspaces at least on the output it is on.
Furthermore, the spec gives us the freedom to ignore _NET_WM_DESKTOP when
managing a window if we have good reason to. In our case, we give window
swallowing a higher priority since the user would likely expect that and we
want to keep placeholder windows only around for as long as we have to.
However, we do prioritize this property over, for example, startup
notifications.

It should be clear for callers of this function that this is an internal
function that skips certain validations which might be important. Therefore
we make it clear that this is an internal function by renaming it.

This patch migrates all decoration rendering of i3 to cairo. Using the
compile switch CAIRO_SUPPORT, rendering can be switched back to the
previous XCB behavior, just like with the previous migration to cairo
in i3bar.
This patch also fixes a bug in draw_util.c where copying one surface
to another would use incorrect coordinates if the source coordinates
are not 0, 0.
Furthermore, this patch implicitly fixes some minor issues in the
decoration rendering which would be ignored previously due to the fact
that errors would only show up in the event queue, but not cause the
rendering code path to crash. One example is zero-height pixmaps which
are not allowed. Using cairo, these would cause i3 to instantly segfault,
so this patch avoids this.
Lastly, this patch annotates other issues found but not fixed in this patch
using TODO comments, e.g., the zero-height check not working correctly
and the comment that it should probably work the same way for zero-width
pixmaps.

This commit also reworks the way focusing sticky windows is prevented by not focusing them temporarily at all, but preventing the focus in the first place.

This commit improves the translation of keysyms to keycodes by loading
keymaps using libxkbcommon-x11 and using libxkbcommon for figuring out
the keymap, depending on each keybinding’s modifiers. This way, the
upper layers of complex layouts are now usable with i3’s bindsym
directive, such as de_neo’s layer 3 and higher.
Furthermore, the commit generalizes the handling of different XKB
groups. We formerly had support only for two separate groups, the
default group 1, and group 2. While Mode_switch is only one way to
switch to group 2, we called the binding option Mode_switch. With this
commit, the new names Group1, Group2 (an alias for Mode_switch), Group3
and Group4 are introduced for configuring bindings. This is only useful
for advanced keyboard layouts, such as people loading two keyboard
layouts and switching between them (us, ru seems to be a popular
combination).
When grabbing keys, one can only specify the modifier mask, but not an
XKB state mask (or value), so we still dynamically unbind and re-bind
keys whenever the XKB group changes.
The commit was manually tested using the following i3 config:
bindsym Group4+n nop heya from group 4
bindsym Group3+n nop heya from group 3
bindsym Group2+n nop heya from group 2
bindsym n nop heya
bindsym shift+N nop explicit shift binding
bindsym shift+r nop implicit shift binding
bindcode Group2+38 nop fallback overwritten in group 2 only
bindcode 38 nop fallback
…with the following layout:
setxkbmap -layout "us,ua,ru,de" -variant ",winkeys,,neo" \
-option "grp:shift_caps_toggle,grp_led:scroll" \
-model pc104 -rules evdev
By default (xkb group 1, us layout), pressing “n” will result in the
“heya” message appearing. Pressing “a” will result in the “fallback”
message appearing. “j” is not triggered.
By pressing Shift+CapsLock you switch to the next group (xkb group 2, ua
layout). Pressing “a” will result in the “fallback overwritten in group
2 only” message, pressing “n” will still result in “heya”. “j” is not
triggered.
In the next group (xkb group 3, ru layout), pressing “a” will result in
the “fallback” message again, pressing “n” will result in “heya”,
“j” is not triggered.
In the last group (xkb group 4, de_neo layout), pressing “a” will still
result in “fallback”, pressing “n” will result in “heya”, pressing “j”
will result in “heya from group 4”.
Pressing shift+n results in “explicit shift binding”, pressing shift+r
results in “implicit shift binding”. This ensures that keysym
translation falls back to looking at non-shift keys (“r” can be used
instead of ”R”) and that the order of keybindings doesn’t play a role
(“bindsym n” does not override “bindsym shift+n”, even though it’s
specified earlier in the config).
The fallback behavior ensures use-cases such as ticket #1775 are still
covered.
Only binding keys when the X server is in the corresponding XKB group
ensures use-cases such as ticket #585 are still covered.
With commit c738b2e454 we changed i3 so
that the default keybindings can be used when ISO_Next_Group is enabled,
but bindings which explicitly use Mode_switch have precedence. This
behavior required the use of bindcode instead of bindsym.
With this commit, when switching from group 1 to group 2 using
ISO_Next_Group, i3 will re-translate all keybindings (looking at column
2/3, regardless of whether the keybinding itself specifies Mode_switch)
and re-grab them.
That way, the keybinding “bindsym $mod+x nop foo” will work when
pressing $mod+x without Mode_switch and when pressing the corresponding
$mod+x (different key) with Mode_switch. A binding such as “bindsym
Mode_switch+$mod+x nop bar” will still have precedence.
The intention here is to make bindsym keybindings work well with dual
keyboard layouts (such as {dvorak, us} or {us, ru}), so that users can
switch between groups and still have their (logical) keybindings behave
the same way.

Do not log an XCB_MOTION_NOTIFY event in handlers.c because this
clutters the log.
Only log in the motion notify handler if something important happens.
When a window receives a _NET_ACTIVE_WINDOW message, it can steal the focus. This may not be preferable to all users.
With this directive, the user can choose from one of the following:
1) 'smart' - focus the container if its workspace is visible, otherwise set the urgency flag (default)
2) 'urgent' - always set the urgency flag, do not steal focus
3) 'focus' - always switch focus, never set the urgency hint
4) 'none' - ignore the request entirely (do not switch focus, nor set the urgency hint)

Handle changes to the property _NET_WM_STRUT_PARTIAL by reallocating
screen space in the dock area when the dock client requests a new
position.
This will allow changes to the bar config directive `position` to be
effective on the `reload` command.

Not quite sure why there are so many differences. Perhaps we’ve gotten
out of the habit of running clang-format after every change.
I guess it’d be best to have a travis hook that runs clang-format for us
and reports any problems on pull requests.
Add support for the _NET_WM_MOVERESIZE client message. This message
enables clients to initiate window moving or resizing. Toolkits like
Gtk3 use this message when the user drags a client-side decorated window
by its title bar. When Gtk detects that the window manager does not
support this client message, it uses a slow fallback implementation.

i3 processes changes to WM_CLASS by updating the cached property and
running assignments. This allows the property to be used in criteria
selection.

This removes our last dependency on Xlib! :)
(Okay, an Xlib dependency still comes in through other libraries that we
link against, but it’s not us. Our code is simpler by this change and
uses one less connection to X11.)
This should be the last commit that formats a big bunch of files. From
here on, whenever I merge patches, I’ll run clang-format like described
in the title.
This has multiple effects:
1) The i3 codebase is now consistently formatted. clang-format uncovered
plenty of places where inconsistent code made it into our code base.
2) When writing code, you don’t need to think or worry about our coding
style. Write it in yours, then run clang-format-3.5
3) When submitting patches, we don’t need to argue about coding style.
The basic idea is that we don’t want to care about _how_ we write the
code, but _what_ it does :). The coding style that we use is defined in
the .clang-format config file and is based on the google style, but
adapted in such a way that the number of modifications to the i3 code
base is minimal.
When `focus_follows_mouse` option is on, prevent an uneeded render on
pointer enter when the con is already focused.
This pointer enter might be caused by entering a window decoration of an
already-focused container.
This extra render can cause concurrency issues when focus is set
asynchronously with WM_TAKE_FOCUS.
Allow client requests of type _NET_ACTIVE_WINDOW to switch workspaces if
they indicate they are a pager. Otherwise, set the urgency hint on that
con to indicate that something happened.
This allows task switchers like skippy-xd to work properly.
