Ludvig Michaelsson f627cd77d6 swaybar: signal status command's process group
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.

Tudor Brindus 03daa53a0e swaybar: fail gracefully on tokener creation fail
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.

Tudor Brindus 47f1f9b63e swaybar: use INT_MAX max JSON depth when parsing IPC response
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.

Kenny Levinsen 6271bd06e9 swaybar: Use position from wl_pointer.enter
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.

Closes: https://github.com/swaywm/sway/issues/6109

swaybar: silence missing IconThemePath message
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

Fenveireth 837605d68d swaybar: use text subpixel antialias only where it would look good
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

Ludvig Michaelsson d6ac30753d swaybar: don't expand separator_block_width if separator is false
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".

Hubert Hirtz c5c632aaae Document required '\n' in swaybar-protocol
The following statusbar output is not considered by sway to be following
the swaybar-protocol:

    {"version":1}[[{"full_text":"2.89","urgent":false}],

However this one is:

    {"version":1}\n[[{"full_text":"2.89","urgent":false}],

Both outputs contain a header with the required values and an unfinished
array of objects with the required values, but the first one is showed
verbatim.

Charmander 66b7ac6a82 swaybar: allow status line cleanup to proceed when hidden
`determine_bar_visibility` stops and starts the status command process according to the bar’s visibility. If the bar was hidden during teardown, teardown would stall while waiting for the stopped status command process to exit.

This resumes a stopped status command during teardown and allows, for example, sway to reload or quit without leaving a swaybar instance behind each time.

Fixes #5536.

CONT before TERM as requested in review.

Luke Drummond c22caa54a8 swaybar: ensure correct init order for status_line
`$WAYLAND_SOCKET` is unset by `wl_display_connect` after it has
successfully connected to the wayland socket.

However, subprocesses spawned by swaybar (status-command) don't have
access to waybar's fds as $WAYLAND_SOCKET is O_CLOEXEC. This means any
status command which itself tries to connect to wayland will fail if
this environment variable is set.

Reorder display and status-command initialization so that this variable
is not set and add an assert so we can enforce this invariant in future.

Milkey Mouse 45e4e92172 swaybar: add NULL check when listing workspaces
For some reason my version of sway doesn't show workspace names:

    $ swaymsg -t get_outputs
    Output HDMI-A-1 '(null) (null) (null)' (inactive)
    Output HDMI-A-2 '(null) (null) (null)' (inactive)

Which is weird, but it's no reason to crash swaybar. The field is
totally missing from the JSON, so it ends up doing strcmp(NULL, name)
which is undefined behavior.

Ian Huang 276e0301e0 interpret "subpixel none" as CAIRO_ANTIALIAS_GRAY
See issue #5228. Currently, WL_OUTPUT_SUBPIXEL_NONE is ignored and
CAIRO_ANTIALIAS_SUBPIXEL is still set. This commit checks if subpixel is
set to none and if so, calls set_antialias with CAIRO_ANTIALIAS_GRAY.

Hristo Venev 7affe5c1bd swaybar: fix i3bar relative coordinates when scaling is used
24e8ba048a did not take scaling into account.
The hotspot size used pixel coordinates, the absolute coordinates were logical,
and the relative coordinates were completely wrong.

This commit makes all coordinates use logical values. If
`"float_event_coords":true` is sent in the handshake message, coordinates are
sent as floating-point values.

The "scale" field is an integer containing the scale value.

Brian Ashworth 97f9f0b699 parse_color: return success + drop fallback color
This is the first in a series of commits to refactor the color handling
in sway. This changes parse_color to return whether it was success and
no longer uses 0xFFFFFFFF as the fallback color. This also verifies that
the string actually contains a valid hexadecimal number along with
the length checks.

In the process of altering the calls to parse_color, I also took the
opportunity to heavily refactor swaybar's ipc_parse_colors function.
This allowed for several lines of duplicated code to be removed.

Konstantin Pospelov fa0abaf7cf swaybar: do not retry search for tray icons
In case a tray icon cannot be found or does not have a desirable size,
swaybar retries the search again and again, which increases load on disk
and CPU. This commit solves it by storing target_size for each icon, so
that swaybar does not search for an icon of some size if it already tried to.

Fixes #3789.
