test: split the tests into one test case each

2020-02-11T10:57:42+00:00

For debugging it's more important to be able to quickly run a single test
rather than grouping them together, we don't have thousands of tests here
anyway. So let's add a macro to put every test func into its own TCase,
allowing for test selection via the environment variable CK_RUN_CASE.

Don't read events unless required

2019-03-19T01:02:52+00:00

With the previous approach, every libevdev_next_event() invocation triggered a
read() on the device fd. This is not efficient, the kernel provides whole
event frames at a time so we're guaranteed to have more events waiting unless
the current event is a SYN_REPORT.

Assuming a fast-enough client and e.g. a touchpad device with multiple axes
per frame, we'd thus trigger several unnecessary read() calls per event frame.

Drop this behavior, instead only trigger the read when our internal queue is
empty and we need more events.

Fallout:
- we don't have any warning about a too-slow sync, i.e. if a SYN_DROPPED
  arrives while we're syncing, we don't get a warning in the log anymore.
  the test for this was removed.
- the tests that required the specific behavior were rewritten accordingly
- a revoke on a kernel device doesn't return ENODEV until already-received
  events have been processed

The above shouldn't be an issue for existing real-world clients.

test: move the kernel test to the same infrastructure

2018-06-15T05:19:05+00:00

We previously had this separate because it tested separate things. Now the
setup is generic enough that we should just re-use it.

test: fix kernel test for revoke after

2014-04-02T01:35:12+00:00

dev2 by definition doesn't initialize, we expect it to fail. Freeing it after
is a bad idea. Also initialize it to NULL so this is a bit more obvious now.

Add a test for EVIOCREVOKE

2014-02-25T21:22:04+00:00

New in 3.12, EVIOCREVOKE revokes access to an evdev device. This is unlikely
to be used by a libevdev user, see.

This patch adds a new test-kernel binary that tests the kernel API directly.
