9 years agoIntroduce device groups to group logical devices together
Peter Hutterer [Thu, 5 Feb 2015 03:39:04 +0000 (13:39 +1000)]
Introduce device groups to group logical devices together

Devices like Wacom tablets have multiple event nodes (touch, pad and stylus).
This requires some logical grouping, e.g. setting an Intuos 5 tablet
left-handed effectively turns it upside down. That then applies to both the
stylus and the touch device.

Merging the devices into one struct libinput_device is not feasable, it
complicates the API for little benefit. A caller would still need access to
all subdevices to get udev handles, etc. Some configuration options apply to
the whole device (left-handed) but some (may) only apply to a single subdevice
(calibration, natural scrolling).

Addressing this would make the libinput API unwieldly and hard to use.

Instead, add a device group concept. Each device is a member of a device
group - a singleton for most devices. Wacom tablets will have a single group
across multiple devices, allowing the caller to associate the devices together
if needed.

The API is intentionally very simple and requires the caller to keep track of
groups and which/how many devices are in it. The caller has more powerful
libraries available to do that than we have.

This patch does not address the actual merging of devices into the same
device group, it simply creates a new group for each new device.

Olivier Fourdan [Thu, 5 Feb 2015 13:33:31 +0000 (14:33 +0100)]
Fix an abort if the device speed is NaN

When using libinput with xf86-input-libinput, the device speed is
represented as a float passed via X properties.

If a buggy client gives a broken value, the conversions that occur
can cause the value of speed to be NaN (not a number), aka infinity.

In C, any comparison with NaN always gives false, whatever the value.

So that test in libinput_device_config_accel_set_speed():

   (speed < 1.0 || speed > 1.0)

will necessarily return FALSE, defeating the test of range.

However, since since any comparison with NaN is false, the
opposite assert() in accelerator_set_speed():

   (speed >= 1.0 && speed <= 1.0)

will be false as well, thus triggering the abort() and the crash of
the entire X server along with it.

The solution is to use the same construct in both routines, so that
it fails gracefully in libinput_device_config_accel_set_speed().

test: add per-device udev rule support

Don't rely on a magic version tag, instead let a device define a udev rule and
drop that into the udev runtime directory before the device is created.

There are a couple of caveats with this approach: first, since this changes
system-wide state it may cause issues on the device the test suite is run on.
This can be avoided if the udev rules have filter patterns that ensure only
test devices are affected.

Second, the check test suite aborts but it doesn't run the teardown() function
if a test fails. So far this wasn't a problem since uinput devices disappear
whenever we exit. The rules files will hang around though, so an unchecked
fixture was added to delete all litest-foo.rules files before and after a test
case starts. Unchecked fixtures are run regardless of the exit status of the
test but run in the same address space - i.e. no ck_assert() usage.

Also unchecked fixtures are only run once per test-case, not once per test
function. For us, that means they're only run once per device (we use the
devices as test case), i.e. if a test fails and the udev rule isn't tidied up,
the next test may be unpredictable. This shouldn't matter too much though.

i.e. provided BTN_TOUCH is down: if BTN_TOOL_FINGER is down, one hovering
touch gets marked as down, if DOUBLETAP is down, two touches are marked as
down, etc.

Add pointer axis sources to the API

For a caller to implement/provide kinetic scrolling ("inertial scrolling",
"fling scrolling"), it needs to know how the scrolling motion was implemented,
and what to expect in the future. Add this information to the pointer axis
event.

The three scroll sources we have are:
* wheels: scrolling is in discreet steps, you don't know when it ends, the
  wheel will just stop sending events
* fingers: scrolling is continuous coordinate space, we know when it stops and
  we can tell the caller
* continuous: scrolling is in continuous coordinate space but we may or may not
  know when it stops. if scroll lock is used, the device may never technically
  get out of scroll mode even if it doesn't send events at any given moment
  Use case: trackpoint/trackball scroll emulation on button press

The stop event is now codified in the API documentation, so callers can use
that for kinetic scrolling. libinput does not implement kinetic scrolling
itself.

Not covered by this patch:
* The wheel event is currently defined as "typical mouse wheel step", this is
  different to Qt where the step value is 1/8 of a degree. Some better
  definition here may help.
* It is unclear how an absolute device would map into relative motion if the
  device itself is not controlling absolute motion.
* For diagonal scrolling, the vertical/horizontal terminator events would come
  in separately. The caller would have to deal with that somehow.

9 years agotest: add helper function for checking for a specific event type
Peter Hutterer [Thu, 18 Dec 2014 01:29:32 +0000 (11:29 +1000)]
test: add helper function for checking for a specific event type

In a few tests we care about that a specific set of events are in the queue
but not about the details of the events (usually checked elsewhere). Instead
of manual loops, provide a helper function that also checks that there is at
least one of those events in the queue.

9 years agotest: switch touch points around for semi-mt tap-n-drag testing
Peter Hutterer [Thu, 18 Dec 2014 03:52:36 +0000 (13:52 +1000)]
test: switch touch points around for semi-mt tap-n-drag testing

The tests ignored it when motion events never happened - but that's mostly
what these tests are about. This only happened for semi-mt devices that use
the bounding box only, not separate touch points. Switching the touch points
around that the bounding box doesn't interfere causes the test to work as
expected.
