The values of a Rect are unsigned, but can contain signed values.
Using MAX when the value is negative causes incorrect behavior and
makes the result stay negative, which is what we wanted to avoid here
in the first place.
Fix by properly casting the value for the comparison.
fixes#2094
If a window with border is set to "border none" and then closed, we would
call cairo_destroy / cairo_surface_destroy twice, causing an assertion
failure in cairo as the objects already had zero references the second
time. We fix this by explicitly setting these objects to NULL.
relates to #1278
With this patch, we use 32-bit visuals per default whenever it is
available. Otherwise, we fall back to the actual root window's
depth, which will typically be 24-bit.
Before this patch, we already used 32-bit depth for containers with
a window that uses 32-bit. However, this means that we didn't use
32-bit for split parent containers on which decoration is drawn.
For 32-bit windows using transparency, this caused a graphical glitch
because the decoration pixmap behind it would show through. This
behavior is fixed with this change.
relates to #1278
Such containers never require a pixmap anyway. In particular for the __i3
output (used for the scratchpad workspace), this would cause an allocation
error anyway because it can be very big -- so big, in fact, that X cannot
allocate the pixmap for it.
Until now, this error was silently ignored due to the fact that we did not
create the pixmap checked (and asserted its success), but with cairo this
would cause a crash because we'd try to create a surface for a pixmap
which doesn't exist.
relates to #1278
With this patch we remove the temporary draw_util_colorpixel_to_color
function we introduced previously by parsing the colors as color_t to
begin with.
relates to #1278
We return early from drawing functions if the surface to draw to is not
initialized properly. There is no immediate need to do so, at least no
crashes have been observed, but it mirrors the previous behavior a bit
more closely. Furthermore, i3 should not crash due to not being able to
make some rendering call, so this provides some stability.
relates to #1278
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.
relates to #1278
This patch fixes a bug when copying one surface to another.
Since it only exposes itself when used with non-trivial source
coordinates, it didn't surface before when only used for i3bar.
relates to #1278
In order to prepare for using cairo for rendering i3 decorations,
we need to make the draw_util.c from i3bar available via libi3 such
that both i3bar and i3 can use it.

Mouse bindings that target the window that was clicked send the command
to the parser with `con_id` of the clicked window serialized base 16
for compatability with FreeBSD. See 7c2842e for explaination.
Set base to 0 for strtol to handle base 16 numbers for that reason.
This allows mouse bindings that target specific windows to work
correctly. Without this change, the focused window is always targetted
rather than the window that was actually clicked.
Regression introduced in b744c5e.
With this patch, we support the special value "0" for _NET_WM_USER_TIME
on a window upon managing it, which indicates that the window shall not
be focused.
fixes#2064
This reverts commit 9692c1498b.
That commit accidentally defaulted to group mask 1, but the default
should be to match any group mask, so that having multiple layouts
loaded at the same time works.
fixes#2062
With this patch, we only grab the scrollwheel buttons (4 and 5) when
managing a window if a whole window key binding exists for these buttons.
This allows both of these usecases:
- Bindings to scrollwheel buttons using --whole-window (see #1701).
- Scrolling in a window without focusing it if no such binding
exists (see #2049).
Furthermore, we drop all button grabs and regrab them after a config
reload in order to reevaluate the new bindings correctly.
fixes#2049
We refactor the button grabbing into a function to allow the next patch
both to
- conditionally grab different sets of buttons
- grab the buttons again when reloading the config.

With the recent cairo bugfix, we can now switch to using cairo for
rendering i3bar per default by raising the minimum version of cairo
to 1.14.4, if this cairo version is available.
resolves#2048
As there is no need to keep autostart commands in memory, we can safely
remove them as soon as they have been executed. As we previously didn't
clear them at all during config reloads, this also fixes a memory leak.
Note that neither autostarts nor autostarts_always is executed during
config reloads, so removing them from memory is fine as an i3 restart
will cause them to be parsed again.
fixes#2044
1. i3 config validation failed when the new line is missing from the end of file.
The error was: "ERROR: Your line continuation is too long, it exceeds 4096 bytes".
It is wrong to assume that there is always a '\n' at the end of each line in the config file.
(Not for the last line.)
Fix it via adding a end-of-file check.
2. See the issue #2051. (https://github.com/i3/i3/issues/2051)
This patch introduces the possibility to specify the tray_output directive
multiple times. All values will be used by i3bar, in the order they are
given.
This way, a single bar configuration can be used for several machines with
internal output names "eDP1" and "LVDS-0" by specifying tray_output for both.
Any external output (e.g., "DP-0") will still not receive the tray. The same
effect can be achieved by using "primary", but forces the user to couple the
tray display to the primary output which may not be desirable behavior.

This patch extends the previously introduced flag --no-auto-back-and-forth
to also apply to
move window to workspace <name>
move window to workspace number <number>
