This fixes two real bugs:
- TimedRobot had a m_period that was hiding the IterativeRobotBase m_period
and was not getting initialized.
- PDPSim was swapping two parameters to getCurrent()
A hash is stored for each native library with the name libraryName.hash.
If the library is not found on the system search path, it is extracted to a cache directory.
Extracted libraries are named with the hash appended, so the library will not be
re-extracted if one with the same hash already exists.
Hashing without the hash file requires double traversing if the file is not in the cache,
but it is still faster than creating a new file in most cases. This won't be needed
after opencv is updated to provide a hash as well.
JavaDoc cannot handle redirects so HTTP link does not work anymore.
It also looks like javadoc.options was the wrong thing to set.
Options properly connects external docs to ours.
Re-enabled warnings so these things will pop out if they turn up again.
SendableBuilder.setActuator() sets the .actuator key in the network table
so dashboards can change behavior on the client side if desired, and also
sets a local flag (retrievable via isActuator()).
Both make drive bases actuators and call setSafeState on them.
This echos back the "selected" value to the "active" key to enable dashboards
to display positive feedback to the user that the value is actually set on
the robot side.
Also fixes SendableChooser so it can be safely added to multiple tables.
Changes to "selected" in any table will result in all "active" values being
updated.
Now that adding SendableChooser to multiple tables is supported, an ".instance"
key enables dashboards to treat the same SendableChooser as a common instance
if desired.
This indicates whether or not the Sendable listeners are installed.
It is set to true when SendableBuilder.startListeners() starts the listeners,
and set to false when SendableBuilder.stopListeners() stops the listeners.
This allows dashboards to choose to change their widget display based on
whether or not the value is actually controllable.
This allows two streams with different compression levels, and also allows
a stream to receive a different compression level than provided by a JPEG
camera (decompress and recompress).
Some cameras will accept a different resolution as the mode but then provide
JPEG images of a different size. Trust the JPEG image size if available.
This also validates the JPEG image is actually JPEG.
The old headers were moved into folders because doing so avoids polluting
the system include directories.
Folder names were also normalized to lowercase.
This implements enough of the UDP and TCP protocol used by the FRC
driver station to allow us to talk to either QDriverStation or to the
real Driver Station.
This was inspired by a similar function in Toast by Jaci, and also
uses a lot of the research found in the QDriverStation project.
* Fix bugs in PacGoat Java example that prevent it from working.
We have conflicting ports in use, each of which causes a crash
at startup. These changes fix those issues.
* Change to avoid a crash in Visual C++ when running simulated code.
Without this change, we would get a crash in SendableRobotBase when
constructing a Twine from the 'kOptions' constant string;
we'd get an unable to access memory exception.
