This is similar to #3820 but does not use qsort but an insertion sort in
con_attach.
Since each bar block automatically gets its own incremental bar id,
bards end up being sorted according to their definition order in the
config file.
For i3bar, the WM_CLASS is modified to include an instance name which
depends on the bar_id. This could be useful for other reason, e.g. users
targeting a specific bar instance.
Fixes#3491
This change only affects clients that are subscribed to events, which
should be the main cause of our problems.
In the common case (no buffered data) the behaviour doesn't change at
all: the message is sent directly, no ev_io / ev_timeout callback is
enabled. Once a write to a client's socket is not completed fully
(returns with EAGAIN error), we put the message in the tail of a queue
and init an ev_io callback and a corresponding timer. If the timer is
triggered first, the socket is closed and the client connection is
removed. If the socket becomes writeable before the timeout we either
reset the timer if we couldn't push all the buffered data or completely
remove it if everything was pushed.
We could also replace ipc_send_message() for all client connections in
i3, not just those subscribed to events.
Furthermore, we could limit the amount of messages stored and increase
the timeout (or use multiple timeouts): eg it's ok if a client is not
reading for 10 seconds and we are only holding 5KB of messages for them
but it is not ok if they are inactive for 5 seconds and we have 30MB of
messages held.

Including config.h is necessary to get e.g. the _GNU_SOURCE define and
any other definitions that autoconf declares. Hence, config.h needs to
be included as the first header in each file.
This is done either via:
1. Including "common.h" (i3bar)
2. Including "libi3.h"
3. Including "all.h" (i3)
4. Including <config.h> directly
Also remove now-unused I3__FILE__, add copyright/license statement
where missing and switch include/all.h to #pragma once.
We strive to avoid conditional compilation in i3 as much as possible.
cairo and pangocairo have been around long enough in the versions that
we need that it’s time to unconditionally depend on them.
Also update DEPENDS with the last-known-good-versions while at it.
We now build a docker base container based on debian sid (where the very
latest packages are available). That base container is updated once a
month, or whenever travis-build.Dockerfile or debian/control change, but
re-used for subsequent travis runs. While the initial build might take
up to 15 minutes, subsequent builds typically run in a minute or two.
All the different steps that we run on travis are now factored into
separate scripts in the travis/ directory.
Switching to docker should also help with issue #2174.
This patch moves the title_format information from windows to containers.
Furthermore, it allows correctly setting it on window-less containers and
displays the title accordingly for split containers.
We now also dump and read title_format in GET_TREE / during restarts.
fixes#2120
Corrects the cases where the colorpixel is not 0xRRGGBB : we have to
use the full color_t struct to describe font colors, as Pango expects
RGB values and not an XCB colorpixel value.
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.

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.

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
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.
relates to #1278
This patch creates all necessary windows for i3bar with 32-bit visuals if available.
It also introduces the possibility to define RGBA colors (next to RGB colors), which
allows the user to set the opacity of any color. This requires running a compositor.
With this patch we also start supporting _NET_SYSTEM_TRAY_VISUAL, which is necessary
for the tray icons so they create the tray window with the correct depth and visual.
* common.mk: use -lsocket -liconv -lgen on Illumos/Solaris
* mkdirp: return int and accept a mode argument
* use i3's mkdirp on everything except Illumos
The format string set with "title_format" can contain the placeholder "%title" which will be replaced with the actual window title.
By not overwriting window->name itself, we make sure that assignment matching still works as expected.
fixes#1723
1. Add a function writeall and make swrite wrap that function. Use either writeall or swrite, depending on whether we want to exit on errors or not.
2. Fix warnings when compiling with a higher optimisation level.

Add `markup` to the i3bar protocol as a block member.
This is a string that determines how the block should be parsed as
markup. "pango" indicates the block should be parsed as Pango markup.
"none" indicates the block should not be parsed as markup.
Parse text within workspace buttons and the i3bar statusline as Pango
markup. This lets people specify things like font weight, text color,
background color, font size, and font family in the text of i3bar.
fixes#1468
When loading a new font with `load_font`, free the previously loaded
font with `free_font`.
If no font is loaded, `free_font` will simply return (instead of
crashing because of a double free).
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 avoids flooding stdout every time some text (e.g. a window
decoration) is drawn, yet leaves the message in place when it’s actually
relevant (upon DPI changes).
fixes#1115
Since the macro PATH_MAX is not defined on every system (GNU/Hurd being
one of those who do not define it), we remove all references to this
macro. Instead, we use a buffer of arbitraty size and grow it when
needed to contain paths.
This removes code duplication, which will be useful for a subsequent
commit.
Furthermore, we now don’t open X11 connections unnecessarily in some
corner cases.
