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.
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.
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.
This adds complete support for the barconfig_update ipc event. This also
changes the bar command and subcommand handlers to correctly emit the
event. This makes it so all bar subcommands other than id and
swaybar_command are dynamically changeable at runtime. sway-bar.5 has
been updated accordingly
This allows swaybar to become visible when the mode changes (to any
mode other than the default). swaybar will be hidden again when the
modifier is pressed and released or when switching back to the default
mode.
This also applies the same logic to visible by urgency to hide swaybar
when the modifier is pressed and released.
These changes are to match i3's behavior.
This fixes a typo on the malloc line in ipc_send_workspace_command. The
plus one to the size for the null-terminator was outside of the malloc
call, which was causing the incorrect pointer to be freed later in the
function.
This commit mostly duplicates the wlr_log functions, although
with a sway_* prefix. (This is very similar to PR #2009.)
However, the logging function no longer needs to be replaceable,
so sway_log_init's second argument is used to set the exit
callback for sway_abort.
wlr_log_init is still invoked in sway/main.c
This commit makes it easier to remove the wlroots dependency for
the helper programs swaymsg, swaybg, swaybar, and swaynag.
This modifies `bar_cmd_tray_bindsym` to use `get_mouse_bindsym` for
parsing mouse buttons. This also introduces `bar_cmd_tray_bindcode`,
which will use `get_mouse_bindcode` for parsing mouse buttons. Like with
sway bindings, the two commands are encapsulated in a single file to
maximize shared code.
This also modifies tray bindings to work off of events codes rather than
x11 buttons, which allows for any mouse buttons to be used.
For `get_bar_config`, `event_code` has been added to the `tray_bindings`
section and will include to event code for the button. If the event code
can be mapped to a x11 button, `input_code` will still be the x11 button
number. Otherwise, `input_code` will be `0`.
Adds the bar subcommand `status_padding <padding>` which allows setting
the padding used for swaybar. If `status_padding` is set to `0`, blocks
will be able to take up the full height of the bar.
This modifies `bar_cmd_bindsym` to use `get_mouse_bindsym` for parsing
mouse buttons. This also introduces `cmd_bar_bindcode`, which will use
`get_mouse_bindcode` for parsing mouse buttons. Like sway bindings, the
two commands are encapsulated in a single file with shared code.
This also modifies swaybar to operate off of event codes rather than x11
button numbers, which allows for any mouse button to be used.
This introduces two new IPC properties:
- For `get_bar_config`, `event_code` has been added to the `bindings`
section and will include to event code for the button. If the event code
can be mapped to a x11 button, `input_code` will still be the x11 button
number. Otherwise, `input_code` will be `0`.
- Likewise for `click_events`, `event` has been added and will include
the event code for the button clicked. If the event code can be mapped
to a x11 button, `button` will still be the x11 button number.
Otherwise, `button` will be `0`.
Adds the bar subcommand `gaps <amount>|<horizontal> <vertical>|<top>
<right> <bottom> <left>` to set gaps for swaybar. Due to restrictions on
margins for a layer_surface, only the sides that are anchored to an edge
of the screen can have gaps. Since there is support for per-side outer
gaps for workspaces, those should be able to be used instead for the
last side.
Since wayland does not currently allow swaybar to create global
keybinds, this is handled within sway and sent to the bar using a custom
event, so as not to pollute existing events, called bar_state_update.
As well as adding the hidden_state property to the bar config struct,
this commit handles barconfig_update events when the mode or
hidden_state changes, and uses a new function determine_bar_visibility
to hide or show the bar as required, using, respectively,
destroy_layer_surface, which is also newly added, and add_layer_surface,
which has been changed to allow dynamically adding the surface.
The received json is handled outside of the case statement, which will
allow better extensibility.
This commit also introduces the variable bar_is_dirty, the return value
signifying whether the bar requires rendering.
This distinguishes the binding mode from the distinct config mode, as
well as removing mode_pango_markup from the config struct where it
should not be present.
Swap return with break in IPC_EVENT_WORKSPACE case to free resp.
Change default return value to true. This causes IPC_EVENT_MODE changes to be
rendered instantly.
