We perform bridged synchronous calls into liblivoxProto1 in order
to support attach/detachDeviceReq. We'll eventually make
attachDetachDeviceReq fully asynchronous but for now we're happy
that we have this working driver for this fairly tricky device.
We tested it.
It's important to note that between test runs, we need to take
into account the fact that the Avia stops sending bcast adverts
when it's been handshaken.
So the retry-delay-ms may be longer due to the fact that the Avia
may not be sending adverts for a good portion of that retry-delay-ms
time.
Preliminary draft implementation. Unsurprisingly it doesn't
work. The handshake doesn't get accepted by the device it seems?
And we can't receive bcast dgrams since we're blocking
synchronously -- therefore we're not processing the incoming UDP
dgrams.
We've added two new libs:
* commonLibs/livoxProto1
* senseApis/livoxGen1
They currently get to the point of detecting my Livox Avia on the
network over UDP. This was really easy to get done in one night
using boost::asio and Cursor, honestly.
This language is used broadly to specify how to attach (and thus
also how to detach) devices to/from Salmanoff. The next bit of work
we'll do is split off the DSL parsing from the management of the
list of parsed binary attached spec objects.
We'll be creating a PipeDeviceAttachmentParser, and later on when
we support URDF, we'll create a URDFDeviceAttachmentParser.
xcbXorg is a connection manager lib that'll be used in common by all of
the xcb API frontends: xcbMouse, xcbWindow and xcbKeyboard. We moved
it into commonLibs to make it make more sense.
We also cleaned up the M4 scripting around AC_ARG_VAR-ing new common
libs as well as sense/wilzor libs.
We now use param keys in the API params to choose what type of ID
the deviceSelector holds, and how to match it.
* dev-id/devid: matches by ID.
* dev-substr/dev-substring/devsubstr: Matches window name by substring.
* dev-string/devstr/dev-str: matches window name by exact whole string.
This patch adds some nicely weighty code for connecting to X displays
and managing those connections. Attaching devices will automatically
connect to their required X display. Removing all devices dependent
on a given X display connection will also disconnect from that
Xdisplay.
We decided to get rid of the C FFI for libs. It was becoming too intricate
and complicated. It was becoming a technical burden and expanding into
too much extra code. It's unfortunate, but we'll have to give up on getting
out-of-tree hot-loadable libraries the easy way.
It's possible to still do it with cross compilation or by keeping track
of the libstdc++ version that the running harikoff binary was compiled
against. Then we can ensure that our loadable lib code is linked against
that same libstdc++ code and this should ensure ABI stability.
We also had to write conversion constructors and so on to CSenseDeviceDesc.
The technical debt that's being piled up from this C FFI is excessive.
I think we'll end it here. API Libs will have to be written in C++
from now on. API Lib interfaces will be in C++.
We'll use cross compilers to ensure stability for out-of-tree lib
development.
* Renamed some of the Sense API lib classes
(CSensorDeviceDesc=>CSenseDeviceDesc,
SensorDeviceDesc=>SenseDeviceDesc).
* Moved SenseApiDesc into /include/user/senseApiDesc.
* Add conversion constructor to convert from SenseDeviceDesc
to
* Wireframe mlo_initializeInd to call xcb_connect().
* Add $(XCB_LIBS) to libxcbXorg_LDFLAGS.
* Wireframe mlo_attachDeviceReq().
Also, SenseApiDesc: initializeInd() now takes void. We no longer
try to pass a struct of marionette-role ops into the libs. We'll
be using message queueing for the handshake side of async calls now.
SenseApiDesc:
* Use a number count for num exported implexor APIs instead of
NULL-terminated list.
* Add sanity checker functions for structs.
SenseApiLib:
* Invoke the new sanity checkers on new Lib objects.
* SenseApiDesc is now a member object instead of being
pointed to.
SenseApiManager:
* loadSenseApiLib now calls the SenseApiDesc getter function.
* loadSenseApiLib now fills out the SenseApiLib class object.
New Sense API Mgmt Sub-API:
This sub-api (metalanguage, some might call it) is used to initialize
the lib's connection to the provider. After this call, the lib should
be ready to attach new devices to its provider on behalf of Hk.
