An address of a variable can never be NULL, so checking it doesn't make
sense; and `destroy_buffer()` can operate on already destroyed buffers
anyway.
Fixes#6780
sway#6504 simplified rendering code by setting scaling at cairo, but
that also changed button position records into ones without scale
multiplication, breaking button events. This fixes it by not multiplying
scale on events handling as well.
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.
Closes: https://github.com/swaywm/sway/issues/5991
In case `wl_display_roundtrip` returns an error after registering for
events, print a more user-friendly error message and exit.
Previously, if the build did not have assertions enabled, this would
likely result in a segfault. With assertions enabled, it's not user
friendly to terminate with internal implementation information.
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.
Note: since strtoul() has no real error return code (both 0 and
ULONG_MAX may be returned on both success and failure), set errno=0
before calling strtoul().
If the XCURSOR_THEME and/or XCURSOR_SIZE environment variables are
set, use the theme and size they define.
If they're not set, use the same defaults as before (system default
theme, size=24).
The new upstream is https://github.com/swaywm/swaybg
This commit also refactors our use of gdk-pixbuf a bit, since the only
remaining reverse dependency is swaybar tray support.
This revamps the type configs for swaynag. All sizing attributes for
swaynag are now `ssize_t` instead of `uint32_t` to allow for a default
value of `-1`, which allows for `0` to be a valid value. Additionally,
the initialization of the type configs has been changed from a simple
calloc to use a new function `swaynag_type_new`. `swaynag_type_new`
calloc's the memory, checks for an allocation failure, sets the name,
and all sizes to -1. The layering order has also been changed to
default, general config, type config, and as highest priority command
line arguments. Finally, `swaynag_type_merge` has been modified to
handle the layering and sizing changes.
Currently on master, swaynag will retrieve a pointer instance whenever
the capabilities change and WL_SEAT_CAPBILITY_POINTER is set. The
pointer instances were never being destroyed so swaynag received events
multiple times due to having several instances of the pointer.
This fixes it so if there is already a pointer instance, swaynag does
not attempt to retrieve another. Additionally, if the pointer
capability is removed, the pointer instance is destroyed.
When swaynag is run with the -l/--detailed-message option, a crash may
occur if the detailed message read from stdin is large enough. E.g.:
swaynag -m hello -l < ~/.config/sway/config
The root cause is that the read_from_stdin() function under-allocates
memory for the destination buffer which causes that buffer to be overflowed
when copying line data to it with snprintf().
The repair is to allocate one more byte for the terminating null byte.
N.B. although getline() returns the number of bytes read excluding a
terminating null byte, the line buffer is terminated with a null byte. Thus
we have a guarantee that the line buffer will be null terminated (which is
important when copying with snprintf()).
In addition to removing unused code, two minor problems are fixed:
(1) `resize set` and `resize adjust` did not error when given
too many arguments.
(2) `orientation` was incorrectly overridden to be 'U' for
scroll events in the swaybar tray `handle_click` 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.
If there are no arguments or invalid arguments given, swaynag will free
`swaynag.details.button_details` under the `cleanup` label in main. It
then called `swaynag_destroy`, which would attempt to free it again.
Since `swaynag.details.button_details` is either freed on line 106 of
main (when there is no detailed message) or added to `swaynag.buttons`
on line 103 of main, there is no reason to manually free it in
`swaynag_destroy`.
Although I cannot reproduce a double free on my system, for some reason,
it should have actually resulted in a double free in all code paths.
When the cursor surface gets updated, it should be damaged.
This also bumps up `wl_compositor` to version 4 to be able to use
`wl_surface_damage_buffer`.
In `i3 4.16`, `i3-nagbar` introduces the flags `-B/--button-no-terminal`
to run the action directly instead of inside a terminal. This implements
the flags for swaynag for compatibility.
Since swaynag does not use an equivalent to `i3-sensible-terminal`, the
flags `-b/--button` only uses a terminal when the environment variable
`TERMINAL` is set, otherwise it acts the same as these new flags.
