Add documentation for axis updates without a tracking ID

2014-03-21T01:27:27+00:00

If a touch starts and terminates while in SYN_DROPPED, the tracking ID appears
to stay at -1, but the other axes may update. We need to pass these on to the
client since the kernel may buffer the next event with the same value
otherwise. Note this in the documentation so that client's don't create touch
points based on out-of-touchpoint updates.

uinput: check for asprintf failure

2014-03-18T23:36:41+00:00

This doesn't really do much here, but strictly speaking: if asprintf returns
-1, devnode is undefined. So reset it to NULL to avoid weird pointers. And
also free the rest of the names if we ever have more than one device - which
also shouldn't happen.

Shut up another warning

Shut up compiler warning

2014-03-18T23:36:41+00:00

Triggered with -O

../libevdev/libevdev-util.h:58:20: warning: ‘mask’ may be used uninitialized
in this function [-Wmaybe-uninitialized]

Optimisation clearly shuffles things around here: in the code, if no max is
found, we return -1 and bail out before we access mask.

Sanitize events when we're skipping sync as well

2014-03-18T23:36:41+00:00

If a client doesn't sync expliciltly, make sure we sanitize the events when we
update the internal library state.

doc: move the section for the internal test suite down

2014-03-13T23:38:18+00:00

"Related Pages" in doxygen are ordered in the order they appear in the source
file. The internal test suite is least likely to be of interest to the
reader, so move it to the bottom.

doc: Add documentation on how SYN_DROPPED is handled

2014-03-13T23:38:18+00:00

This is getting a bit complex, so add some high-level documentation that we at
least know what we're trying to do.

Add a documentation note to update the slot after syncing

2014-03-07T00:16:16+00:00

Clients may not care about the events generated during SYN_DROPPED, but the
current slot must be updated to avoid a client being out-of-date.
Same with tracking IDs, if they changed, the caller will likely have to update
some internal states.
