0dba8769d4 ei: remove unused server_version and client_version fields 2023-03-03 11:21:26 +10:00
Peter Hutterer
7a2629fe42 meson.build: drop the protocol version 
This is no longer applicable now that we have interfaces of varying
versions.

273eda39ca Move the C proto templates to the src directory 
These are very specific to libei/libeis, so let's not leave them
somewhere where they look like official bindings or something.

29cf354de6 scanner: drop the Target class, push to templates 
The Target was specific to libei/libeis, it resolved to "ei" or
"eis_client" depending on which component we were building. But that's
specific to our C implementation here, so let's push it into our C
implementation templates.

e0d0c1af61 eis: require ei_seat and ei_devices 
A client that skips on announcing those will get connected and
immediately disconnected again. There's no point to libei if you support
neither of those (at least for now).

df99fc923b proto: if the target object no longer exists, don't send events/requests 2023-03-03 11:21:26 +10:00

86dced2c40 eis: make ei_connection/callback/pingpong required interfaces 
v1 of ei_connection requires callback and pingpong, so let's make all
three required and disconnect a client that doesn't support those.
 2023-03-03 11:21:26 +10:00
Peter Hutterer
a80b19bb2c eis: immediately disconnect a client without the ei_connection interface 
No point going through the setup here, just disconnect immediately.

619b83220d eis: drop the device->id now that it's all protocol-wrapped 2023-03-03 11:21:26 +10:00

6ed610e30e Split the ping/pong request into its own interface 
Leave the ei_callback as-is and instead add ei_pingpong for the same
thing initiated by the server. The interface is otherwise identical but
for the direction it is supposed to flow.

This reduces the possibility of a client accidentally sending a
request when it is supposed to handle an event or vice versa.

f41cc91599 proto: add a ping/pong request 
This is effectively the same as connection.sync, but goes the other way.
This adds the ei_callback.done request.

In libeis this is (currently) enforced immediately after sending the
connection object. Not required there and makes the code a bit messier
but this way we can ensure that any client library handles that part of
the code.

b481eff34c eis: only allow the available caps to bind to a seat 
A client binding with caps >= the seat's current version will get
disconnected now.

ea8df6402a scanner: handle since tags in enum values 2023-03-03 11:21:26 +10:00

8c85b8fc1f protocol: add ei_connection.invalid_object 
This event is to notify the client that an object used in a request was
unknown. This allows the client to work around race conditions like
binding to a seat that was removed.

This is currently the server-side only which is probably enough for now.
The only client-side created objects we have are the callbacks.

34889d4803 scanner: pass the component through as well 
For the cases where we have to add "ei" or "eis" in a random place in
the template.

cfbb906358 protocol: rename type to context_type 
type is a reserved keyword in many languages, let's not make this harder
to use than necessary
 2023-03-03 11:21:26 +10:00

20e425a48d scanner: add the camel_name property to our messages 
This allows for templating into EiConnectionSetup and the like
 2023-03-03 11:21:26 +10:00
Peter Hutterer
58b430039a eis: destroy the eis_connection immediately after sending disconnect 
Requests the client sent on the connection after disconnect
will thus be ignored.
 2023-03-03 11:21:26 +10:00
Peter Hutterer
a0b2cfffa9 scanner: switch to a two-run parsing of the XML file 
On the first run we extract the interfaces only, on the second run all
the rest. This allows us to pass the interface to the Argument where
appropriate.

bde838fd1d protocol: rename the touch capability to touchscreen 
This matches the interface name now, even though the public API right
now still uses TOUCH

da51bc095f brei: add a brei context object 
Having debugging in the brei code is useful, the only way we can do this
is by passing the log handler down.

6721802059 protocol: require the "since" attribute for all messages

0a347f433f protocol: make the connection setup the zero object with a proper handover 
This changes the initial connection negotiation to have the
ei_connection_setup as the pre-existing object id 0. Once the client has
sent all the data to set up the connection, the EIS implementation
replies with a new object ID that is the ei_connection protocol object,
i.e. the main object.

This allows for version negotiation of our main protocol object.

23433d3aff protocol: move the keymap into the keyboard interface 2023-03-03 11:21:26 +10:00
Peter Hutterer
4d9ca1796d protocol: move pointer/keyboard/touch into separate interfaces 
This allows us to have a device support multiple interfaces and evolve
those interfaces individually, e.g. add things to the keyboard interface
without having to bump the touchscreen interface.

Note that due to a name clash with the existing struct ei_touch public
API the protocol interface is named touchscreen.

fadc1853c9 protocol: add the ei_device interface 
Sitting nested below the ei_seat, the client gets a notification for a
device through the ei_seat.device event.

01a2ff2d72 brei: pass the proto object through to send_message 
Makes for easier debugging since we can print names instead of just
ids/opcodes.

2a8661f7ad protocol: move the seat bind to the seat object 
Needs documentation but we can do this when we're done with everything.

b9037ed4ff protocol: check any incoming/outgoing messages for versions 
Don't let a interface version 2 send version 3 request or receive those
events.

aaf72f9263 protocol: add a seat interface 
Incomplete, only supports the initial seat setup but binding to a seat
is still outside this interface.

d95236aa3e Add the ei_callback interface versions 
We can now bump ei_callback to a higher version if the client supports
it.
