`gcc-14` added a new `-Walloc-size` warning that makes sure that size of
an individual element matches size of a pointed type:
https://gcc.gnu.org/PR71219
`sway` triggers it on `calloc()` calls where member size is used as
`1` (instead of member count):
swaynag/config.c:169:65: error: allocation of insufficient size '1'
for type 'struct swaynag_button' with size '48' [-Werror=alloc-size]
169 | struct swaynag_button *button = calloc(sizeof(struct swaynag_button), 1);
3d5ae9813d added logic to change the
underlying wlr_toplevel size for floating containers, but it does it
even if the container has no actual coordinates yet. This doesn't really
make sense to update the toplevel size in this case since there's many
things that could affect the initial coordinates (sway commands,
fullscreen state, etc.). Skip this by doing a crude check to see if the
current container state has any width.
Previous behavior was that only if resolution and refresh rate match
exactly, the mode was accepted. As fallback, the mode with the highest
refresh rate and the same resolution was chosen.
New behavior is that the mode with the closest match for the refresh
rate is used with a limit of up to 1Hz. The fallback behavior stays the same.
Additionally, the logging was made more verbose.
- Optional since Sway 1.6 per swaywm/wlroots@bad1e9afa8
- Deprecated in Sway 1.7 per 67d3d952b6
- Removed in Sway 1.8 per e5728052b5
- Ignored in future versions (keeps root priveleges)
When using the `map_from_region` for pen tables, we will usually make
the available area as big as possible while maintaining the proportions
with the screen.
As most of the tablets uses a 16:10 ratios while the most popular screen
ratios is still 16:9, the argument for most people should be `0x0 1x0.9`
to have the maximum effective area.
However, the argument above won't work because the current code will
treat `0x...` as a hexadecimal number, instead of setting both `x` and
`y` to `0`.
This fix allows the use of the following syntax:
```
input type:tablet_tool {
map_from_region 0x0 1x0.9
}
```
If a floating client resizes itself, sway updates several of its
internal dimensions to match but not wlr_toplevel. This means that the
next time wlroots sends a toplevel configure event, it can have wrong
coordinates that resize the client back to its old size. To fix this,
let's just use wlr_xdg_toplevel_set_size so the wlr_toplevel has the
same dimensions as sway.
Exactly the same as 0183b9d35d but the
logic is onlly applied to xdg_shell and not xwayland.
