Fixes child proccess killing, when status_command is a complex command
like "i3status | wrapper.sh".
Set the process group id of the child process by calling `setpgid` after
forking and before calling `exec`.
The process group ID will be set to the process ID of the forked
process. Processes spawned by this child process will also have this
group ID.
Send signals to the process group with `killpg`. This will send the
signal to all of the process group.
This commit implements the StatusNotifierItem protocol, and enables
swaybar to show tray icons. It also uses `xembedsniproxy` in order to
communicate with xembed applications.
The tray is completely optional, and can be disabled on compile time
with the `enable-tray` option. Or on runtime with the bar config option
`tray_output none`.
Overview of changes:
In swaybar very little is changed outside the tray subfolder except
that all events are now polled in `event_loop.c`, this creates no
functional difference.
Six bar configuration options were added, these are detailed in
sway-bar(5)
The tray subfolder is where all protocol implementation takes place and
is organised as follows:
tray/sni_watcher.c:
This file contains the StatusNotifierWatcher. It keeps track of
items and hosts and reports when they come or go.
tray/tray.c
This file contains the StatusNotifierHost. It keeps track of
sway's version of the items and represents the tray itself.
tray/sni.c
This file contains the StatusNotifierItem struct and all
communication with individual items.
tray/icon.c
This file implements the icon theme protocol. It allows for
finding icons by name, rather than by pixmap.
tray/dbus.c
This file allows for asynchronous DBus communication.
See #986#343
This change allows using numeric character references in workspace names
- for example æ which stands for sharp s. A fix was necessary in
get_pango_layout, since markup and parsed markup had different width.
When using a bar on a named output, load_swaybars() requires the
output to be active (ie. in the root container), but this is not the case if
the bar is added to the last output. To fix this, load_swaybars() is now
called after the output has been added to the root container.
After fixing that, swaybar would segfault due to using the wrong index
variable when loading outputs and config.
When headers were installed in more sofisticated places (but package
config knows it right), it revealed missing paths in CMake
configuration. Lets fix it.
In the i3bar protocol the value of the markup field is a string: "pango"
or "none" rather than a bool. This patch makes swaybar compatible with
that.

Calling `exit` in sway_terminate prevents sway from correctly shutting
down (freeing data, cleanly terminating the ipc server, etc.).
A better way is to exit straight away if the failure occurs before
`wlc_run` and use sway_abort as usual if it occur when wlc is running.
Makes `ipc_recv_response` return a struct with size, type and payload
rather than just the payload string.
This is useful if the type has to be checked on the client.
This extends the i3bar protocol implementation with the following
features from @Airblade/i3:
* background
* border
* border_top, border_bottom, border_left, border_right
A block will now be rendered like this:
```
(border_left + margin) + width + (margin + border_right) + sep
```
Where `border_left/border_right` and their related margin is only drawn
if the `border` is specified and the border has a width > 0 (default is
1).
`border_top` and `border_bottom` does not affect the height of the bar
(no margin is added), thus it will be drawn behind the text if it is too
big. The user should specify a bar height if more space between
top/bottom borders are required.
This should fix the random json related crashes in swaybar.
The crashes occured because the same socket was used for listening on
workspace events and requesting workspace info, resulting in a
unreliable message queue on the socket.
The solution is to use one socket for the events and one socket for
reliably requesting workspace/output info.
I am not sure if this is a correct issue/fix but on my system at least
after an i3bar protocol is detected this while loop never goes back
around meaning it doesnt process the status line anymore.
Swaybar did not correctly handle the SIGTERM sent from sway when
exiting, ultimately leaving the child status_command behind.
This should correctly handle the SIGTERM signal and terminate the
status_command.
Fix#386
Use of busyloop caused high cpu usage for sway because swaybar had to be
redrawn all the time. By using select instead the bar only has to be
redrawn when the status_command changes (i.e. every second) or when the
workspaces are updated.
Fix#345
