Commit 287a0b4 introduced a segfault when validating the i3 config
as the root_screen will not be set in this case, causing a null
pointer dereference.
fixes#2144
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
Re-introduce fully-fledged get_colorpixel function, which enables arbitrary
color depths for the display. The previous code is kept as an optimization for
the case of a true color display, where a X11 roundtrip is unnecessary.
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.
We now only log an error but do not exit when creating the graphics
context fails. While, if this happens, rendering will likely be wrong,
this is still better than terminating the user's session entirely due
to a rendering problem, potentially causing data loss.

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
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.
relates to #1278
We pass alpha channel information to the current text drawing code
and use it if it is available. The previous behavior of using full
opacity for RGB format colors is preserved.
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
If I restart i3 4.10.2 twice, e.g. with
$ i3-msg restart; sleep 3; i3-msg restart
the second time I get the following two errors:
05/22/15 10:46:03 - ERROR: mkdir(/tmp/i3-theo.toAK7N) failed: File exists
05/22/15 10:46:03 - ERROR: Could not create "/tmp/i3-theo.toAK7N" for storing the restart layout, layout will be lost.
The first one is from mkdirp() in src/ipc.c and the second one is from
store_restart_layout() in src/util.c.
Notice that I do _not_ get the ``open()'' or ``Could not write restart layout to
...'' error messages, so the layout writing code after line 260 in
store_restart_layout() succeeded and the layout isn't actually lost. Thus,
these error messages are a bit misleading, especially the second one (which is
triggered by the failure of mkdirp()).
POSIX says about `mkdir -p':
``Each dir operand that names an existing directory shall be ignored without
error.''
Therefore, I suggest the following simple patch that makes mkdirp() succeed if
the named file exists and actually is a directory. This silences the second
error as well.
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.
When `new_window` is given in the config, config validation with `i3 -C`
would segfault.
Add a NULL check in logical_px() to check for the case when the config
is being validated without an X server to prevent this.
014aa7ff74 fixed incorrect align of small
symbols, but also introduced a problem with texts with mixed large and
normal symbols. Fix it by centering the text vertically only if its
height is smaller that the saved font height.
Fixes#1543.
When using Pango to draw text in i3bar, the y-offset of the text is
incorrectly calculated in case all characters in the string to draw are
smaller than the cached font height. Fixes#1494.
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).
We're going to call parse_configuration() very early if -C is given on
the command line. Instead of the previous "only_check_config", which has
been a global variable, we now simply pass use_nagbar as false if we're
just validating.
This causes the whole parsing to run without X and of course without
starting nagbar and displaying the errors to standard out/error instead.
The return code of parse_configuration() is now a boolean which
represents whether an error occured during parsing and the programs exit
code is returned accordingly.
Although the config parser still has a lot of side-effects, we now can
parse without the need to have an XCB connection. A nicer implementation
would be to just set the new font and load it just after we're done
parsing, but to ensure we don't break functionality we just load a dummy
FONT_TYPE_NONE if XCB isn't available. The main reason for going this
route is that it's a bit difficult to test fonts in a distribution
agnostic way without bundling fonts with i3 (or Xdummy to be more
exact).

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.
Receiving EOF from a client is not an error, but rather a standard way a
client may disconnect from the IPC. This should rather be logged from
a consumer of the libi3 ipc_recv_message() function as a normal client
disconnect event.

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).
