Emit property change signals for the IsStatusNotifierHostRegistered and
RegisteredStatusNotifierItems properties in StatusNotifierWatcher,
so code relying on the PropertiesChanged signal, instead of signals
such as StatusNotifierHostRegistered, can work properly.
A library that is affected by this is the libappindicator-gtk3* library
and it can cause tray icons to be missing after starting swaybar due to
a race condition, as follows:
* An application using libappindicator-gtk3 starts, e.g. nm-applet.
* Some time later, swaybar starts.
* swaybar creates the StatusNotifierWatcher.
* libappindicator-gtk3 observes the new watcher, but it sees that
IsStatusNotifierHostRegistered=false, so it falls back to the
Freedesktop System tray protocol.
* swaybar creates the StatusNotifierHost.
At this point, libappindicator-gtk3 should "un-fallback" back to SNI.
However, since swaybar does not emit the PropertiesChange signal on
IsStatusNotifierHostRegistered, libappindicator-gtk3 doesn't get
notified, and stays in fallback state forever.
* As a result, nm-applet will not show in the swaybar tray.
This race can be made reliable by inserting a 1-second long sleep here:
03483ff370/swaybar/tray/tray.c (L57)
(*) Note that the libappindicator-gtk3 library has been mostly replaced
by libayatana-appindicator, which is not affected by this.
The affected version is still used by Arch Linux, source code at:

Currently, swaybar does not gracefully die if it detects
that the dbus connection was lost. Although it's not recommended
to restart dbus without restarting the compositor, it can very
easily happen. In the case it does, compositor's tray should
not consume 100% cpu until it has to be force killed.
apply suggestions
just setting the bar to not running will call teardown and unref the
dbus.
Updating the cursor is not essential, so this change prints
a warning when wl_cursor_theme_load or wl_cursor_theme_get_cursor
fail instead of crashing or exiting.
When `wrap_scroll yes` is configured and there's only one workspace
open, swaybar will mark it as not visible if the user scrolls on it and
eventually incorrectly fail the `active->visible` assert.
Fix this by making sure that new and current workspace aren't the same.
This avoids us from using a bogus background_color value that
mutates as swaybar renders things and deciding opacity depending on
that.
Also remove a redundant full surface clear. Just directly write our
desired background color.
CAIRO_HINT_STYLE_FULL attempts to maximize contrast at the expense
of fidelity, this makes most fonts that haven't been hand hinted,
which makes up the majority of fonts out there, appear much worse.
In the absence of explicitly set hint style, cairo will default to
CAIRO_HINT_STYLE_SLIGHT, which attempts to improve contrast while
retaining fidelity to the original shapes, which is what we want.
The previous commit prioritized hotspots before bar bindings for press events,
which matches i3's behaviour. However, since hotspots don't need to do any
processing on release events, those were not handled, and simply fell through
to `bindsym --release` bar bindings (if any).
This is counter-intuitive, and doesn't match i3's behaviour. Instead in case
a hotspot handles the press event, it should also handle the release event,
doing nothing, but blocking the event from triggering a --release bar binding.
E.g., in Sway, without this commit, this config. shows a text on tray clicks:
bar {
# ...
bindsym --release button1 exec swaynag -m I_got_the_release_event.
}
But the same configuration in i3 (with i3-nagbar) doesn't show the text.

This is consistent with i3bar's behaviour, and for example, allows binding a
command to button1, while still being able to click on tray icons or other
zones on the bar's status line which may have their own bindings.
E.g., in Sway, without this commit, this config. makes tray icons unclickable:
bar {
# ...
bindsym button1 exec swaynag -m You_clicked_the_tray._Want_some_help?
}
But the same configuration in i3 (with i3-nagbar) keeps tray items clickable.

Make the status command a process group leader and change the kill(2)
calls to target the new process group. Signals sent by swaybar will then
be received by both the status command and its children, if any. While
here, check the result of fork(2).
Without this, children spawned by the status command may not receive the
signals sent by swaybar. As a result, these children may be orphaned on
reload.
The issue could be shown by setting the bar to
bar {
status_command i3status | tee /tmp/i3status.out
}
which would leave orphaned processes for each reload of sway
$ ps o pid,ppid,cmd | grep i3status | grep -v grep
43633 43624 sh -c i3status | tee /tmp/i3status.out
43634 43633 i3status
43635 43633 tee /tmp/i3status.out
$ swaymsg reload
$ ps o pid,ppid,cmd | grep i3status | grep -v grep
43634 1 i3status
43635 1 tee /tmp/i3status.out
43801 43788 sh -c i3status | tee /tmp/i3status.out
43802 43801 i3status
43803 43801 tee /tmp/i3status.out
This fixes#5584.
This commit adds missing error-handling to the creation of the tokener
instance. The stack depth parameter is used to initialize an array that
json-c prefaults ahead of time, causing INT_MAX to result in out of
memory errors.
Also drop the depth to 256 to prevent this OOM.
Though this fix is not very satisfactory -- json-c could be made to
not prefault -- it should do for now. At the very least, swaybar will
not crash.
Fixes#6126.
There's no inherent limit on the nesting Sway can generate, and the
default used by `json_tokener_new`, 32, can plausibly be hit during
regular usage.
Fixes#6115.
Only wl_pointer.motion was used to update pointer position, which would
cause issues if the pointer was not moved prior to wl_pointer.button.
This also fixes touch input through wl_pointer emulation, which fires
wl_pointer.button immediately after wl_pointer.enter.
Copied from a similar fix made to swaynag.

IconThemePath is not a standard property in XDG's StatusNotifierItem
specification, so missing this property should not be logged as an error.
This patch changes the log level to SWAY_DEBUG when swaybar queries the
value of IconThemePath so that swaybar won't log the returned message as
an error if IconThemePath does not exist.
Closes: https://github.com/swaywm/sway/issues/6092
Closes#5605
Text Subpixel antialiasing is :
- FreeType makes glyph bitmaps containing coverage percentage for each
subpixel, instead of pixel
- Then draw by performing the blend for each subpixel, instead of pixel (e.g.
dual-source blending in opengl)
And there's only one Alpha channel, so this extra coverage data can't
leave Cairo to reach the compositor through there.
Therefore, it can't work as intended if output text alpha != bar background
alpha. Disable it for those cases, enable it elsewhere
As for color emojis, they are RGBA bitmaps. If drawn with text alpha=1.0
and background alpha=1.0 (should be completely opaque bar), then with
'CAIRO_OPERATOR_SOURCE' then texels with alpha < 1.0 result in a blend with
whatever's behind the bar, instead of the bar background
When swaybar receives the following JSON body
[
{
"full_text": "foo",
"separator": false,
"separator_block_width": 0
},
{
"full_text": "bar"
}
]
it should not draw any separator or any space between the two blocks.
However, since swaybar calculates that separator_block_width
0 is too small to fit any configured separator, it will override the
separator_block_width with some non-zero value. This patch changes
that such that the necessary separator_block_width is only expanded if
the block has 'separator: true'.
This should be in line to what i3 does, as its documentation of the
i3bar protocol for separator states that "[...] if you disable the
separator line, there will still be a gap after the block, unless you
also use separator_block_width".
