6f79797308 test: recover external usb keyboard touchpad combo
This recovers the testing that a USB keyboard plus touchpad combo both
set as external, only its own keyboard should affect to DWT that was
removed when Acer Hawaii combo was set as internal.

This is uncommon as usb touchpads nowadays are set as internal, but,
perhaps someone that adds a quirk for a really external combo also adds
in udev's hwdb the external integration for the touchpad, or perhaps we
should set the integration to external when AttrTPKComboLayout=below is
used for the touchpad.

The issue is if the touchpad is leave as internal every keyboard affect
DWT, not only the one that belongs to its combo.

b58d5a165b tablet: fix handling of AttrPressureRange quirk
tablet_get_quirked_pressure_thresholds() is wrong:
the pressure thresholds for tip press and tip release are swapped around.
This seems to be a regression introduced in commit 4bc27543e9.

This prevents AttrPressureRange from working as intended for tablets,
and causes weird things to happen if it's set.
(For example, when pressure is in the range between
the intended release threshold and the intended press threshold,
the "pressed" status flip-flops between 0 and 1 every frame).

Fix that.

fe1d44637f touchpad: add support for fast swipe when 3fg drag is enabled
This adds a movement threshold (5mm) and a timeout (80ms) to the 3fg
drag gesture. On 3fg down with 3fg drag enabled we immediately send a
GESTURE_SWIPE event. After the timeout expires we check the movement of
the fingers - if it is below the threshold cancel the swipe and hold a
button down (i.e. a 3fg drag). Otherwise, continue with this being a
swipe.

This allows for swipe gestures to be used while 3fg drag is enabled.

Above applies the same way for 4fg with 4fg drag enabled.
Thresholds selected using the "yeah, that seems about alright" method,
intentionally quite low because we assume that users that enable 3fg
drag prefer 3fg dragging over swipe.

33b1d87c08 touchpad: don't disable on external mice until we see an event
Instead of disabling the touchpad as soon as a mouse is seen by
libinput, disable it as soon as a mouse sends an actual event. This
works around the current issues with many devices (touchpads and
keyboards alike) announcing a HID Mouse Application Collection which
gets its own event node in the kernel. That event node usually just sits
there and does nothing but its mere presence disabled the touchpad.

Let's change this and instead only disable once we see an event.

86f19a0978 lua: install a timeout hook before any pcalls to prevent infinite loops
If a lua pcall takes longer than one second, kill the plugin.

How often to call the timeout handler is a trade-off but we err on the
side of "possibly too high" since the overwhelmingly vast majority of
plugins will never trigger it anyway.

Gemini suggests that Lua 5.4 can do ~500k ops per second for string
concat (the slowest listed), Claude suggests 1 to 10 million ops per
second. The test in this patch on my 4y old cheap desktop runs the
timeout hook roughly every 37ms. Any normal plugin will be well and
truly done with its work by then.

dee2d38476 Add libinput_tablet_tool_get_name() for the tool's specific name
If the tool has a name let's provide that to the caller. We have it
easily accessible so let's export it to make everyone's life easier. The
name is provided by libwacom, there is no need for us
to even copy that value since we don't need it ourselves.

Note that at this point effectively only (some) Wacom devices have
meaningful names. Virtually all non-wacom devices will use a generic
tool and even the built-in Wacoms will largely just say "AES Pen".

6b4d1905b6 plugin: always disable wheel debouncing on request
The WHEEL_STATE_NONE check was effectively always false:
- if we didn't receive any event yet, wheel_maybe_disable() wasn't
  called in any code path
- if we did receive a scroll event, the wheel state was either
  WHEEL_STATE_SCROLLING or WHEEL_STATE_ACCUMULATING_SCROLL

Fix this two-pronged: remove the check for WHEEL_STATE_NONE but also
immediately call disable when we disable the feature. We don't carry
enough state in this plugin to really worry about the device being in
a fully neutral state (and realistically the vast majority of use-cases
will likely disable wheel debouncing on new device anyway).

b3f7b4b1ea evdev: add support for SW_KEYPAD_SLIDE
A few devices have a keyboard/keypad which can be slid under the device,
leaving the device with only touch-based interaction. The corresponding kernel
event is reported as SW_KEYPAD_SLIDE [0]. Implement support in libinput.

Since the position of the switch varies across devices, it cannot always be
certain whether the keypad is usable when the switch is in the set position.
Therefore, do not automatically disable the keyboard.

20851b5020 touchpad: add configurable timeouts to disable-while-typing
Touchpads that don't give us useful palm detection data are getting more
common (see e.g. our ABS_MT_TOOL_TYPE quirks). On those touchpads we can
only rely on dwt and palm edge detection which means those two must be
more spot on than ever before.

DWT in particular is more prone to user-specific requirements, the
current timeouts have been insufficient for a number of users. So let's
make them more configurable.

Currently limited to >100ms and <5 seconds to avoid DWT being used in
the xkcd workflow style.

9461d1a9a1 Revert "lua: drop compatibility to 5.1 to allow for luajit"
While luajit seems to be the most popular (and fastest) lua
implementation for higher-level implementations, at the system level
it is relatively unused. Lua 5.4 on the other hand is used by other
system-level components like wireplumber and RPM. In the latter case
this means that lua is already available on every rpm-based distro
without further dependencies.

The performance of 5.4 seems to be acceptable and while luajit may be
faster the extra dependency requires more maintenance. Let's only expose
ourselves to that if absolutely needed.

This is not a strict revert because the code has changed a bit since
with several bugfixes deployed on top.

This reverts commit 2723cadaeb.

a12dc6eba3 filter: differentiate scroll wheel from button scrolling to fix wheel speed
Commit 94b7836456 ("filter: support accelerating high-resolution
scroll wheel events") introduced a regression where high-res scroll
wheel events were incorrectly normalized by DPI. Mice with non-default
DPI (e.g., Logitech G502 at 2400 DPI) had their scroll wheel speed
reduced by the DPI ratio (1000/2400), resulting in 2-3x slower
scrolling.

The "noop" filter functions were actually performing DPI normalization
or applying a constant acceleration factor, which is appropriate for
button scrolling but incorrect for scroll wheels that have their own
units.

Add a filter_scroll_type enum (CONTINOUS, WHEEL, FINGER to match the
public events) passed through the filter_scroll interface. Update all
filter implementations to skip acceleration and normalization for wheel
events while maintaining existing behavior for button scrolling and
touchpad scrolling.

The custom acceleration profile continues to accelerate high-res wheel
events as designed.

Fixes: 94b7836456 ("filter: support accelerating high-resolution scroll wheel events")

eb01a4e73f plugins: add meson option to autoload plugins
Add an option to enable autoloading plugins from the default paths.
This makes testing and adoption for new users easier as they can (if
necessary) rebuild libinput with that option enabled instead of having
to wait for the compositor stack to update.

Autoloading will only use the default paths (/etc and /usr/lib) and will
only happen if the client does not modify those paths since that implies
the client wants to load plugins themselves. A client that adds a plugin
path but doesn't load the plugins is considered buggy anyway.

6b9dbc2a25 lua: remove the inject_frame API
Injecting frame was the first implementation of adding event frames but
it has since effectively been replaced by append/prepend_frame which are
more predictable and easier to support.

In the Lua API injecting frames was only possible within the timer and
the only real use-case for this is to inject events that are then also
seen by other plugins. But that can be achieved by simply ordering the
plugin before the other plugins and using the append/prepend approach.

Until we have a real use-case for injecting events let's remove the API
so we don't lock ourselves into an API that may not do what it needs to
but needs to be supported for a long time.

libinput_tablet_tool_config_pressure_range_set() with whatever
values it has in its config storage. Those values will be 0 and 1 by

bda0c7478e tablet: when configuring a user-defined pressure range, zero the offset
When a user configures a pressure range, the tool would get locked into
the current offset even if that offset was still pending. For example, a
sequence of

- tool in-prox with pressure 50%
- libinput_tablet_tool_config_pressure_range_set(tool, 0.0, 0.9)
- tool out-of-prox, tool-in-prox
- libinput applies the tool config, tool now has a configured range,
  has_offset = true
- tool out-of-prox, tool-in-prox
- update_pressure_range() sees has_offset = true, scales the last offset
  (50%) to the actual offset.

Fix this by resetting the detected offset to zero when we shortcut the
heuristics. A user-defined pressure range should include the tool's
pressure offset anyway, the user knows this much better than our
heuristics.

cc7dfccd22 filter: avoid division-by-zero when delta_time is zero in custom filter
delta_time can be zero when:
- the fallback acceleration function is used for multiple movement types
  (for example, pointer motion and wheel scrolling simultaneously)
- two different methods produce the same movement at the same time
  (for example, button-scrolling and wheel-scrolling)

Reusing the last delta_time is a graceful fallback even if there are
duplicate events or event-ordering bugs.
