The static condition variable was getting destroyed before the DS thread exited,
resulting in a deadlock on program exit when the DS thread tried to notify it.
This change moves the condition variable into the DS thread to avoid the race.
The next line adds a null terminator, but it's cleaner to just do a
std::memcpy() since the code already assumes a null terminator exists in
the source string.
- Build both debug and release binaries
- Append "d" to debug libraries in the style of opencv
- Split shared and static classifiers
- Add raspbian support
This allows HAL_CloseI2C() and HAL_CloseSPI() to be noops, which makes
enabling move semantics in the I2C and SPI wpilibc classes easier and
cleaner.
Fixes#1328.
This makes callback registration completely thread safe.
This patch also uses templates and macros to dramatically reduce the amount of
manual boilerplate.
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.
The old headers were moved into folders because doing so avoids polluting
the system include directories.
Folder names were also normalized to lowercase.
Also switch eventName and gameSpecificData to fixed 64-byte arrays to avoid mallocs and
extra NetComm calls. This behavior matches 2018 LabView.
The DS caching is kept in Java to avoid JNI and/or massive amounts of allocations.
This does not increase latency because Java still only hits NetComm once.
Moving the DS caching benefits all languages other than Java, because it avoids the need
for individual implementations. If caching is ever added to NetComm, it will then only be
necessary to remove it from the HAL and Java rather than all languages.
I don't have a good way to ensure this always works, so this is going to be a documentation issue.
But initializeHardwareConfiguration is now reentrant, so we can just have all tests call it.
Also fix the return type of HAL_IsNewControlData() and HAL_MatchType's type.
Since UsageReporting is intended to be namespaced, it is hidden when this is being used in C.

The models and meshes are not included. We will need
to find an alternate way to reintegrate these and use them.
* Add simulation/gz_msgs back, and build with Gradle.
* Add back in the frc simulation plugins for gazebo.
* Add a new shared library, halsim_gazebo.
This library will become the interface between the
HAL sim layer and gazebo.
* Preserve the first channel number used in created Encoders in the Sim MockData.
This allows us to use the DIO channel number to connect with simulated encoders.
* Have the HAL Simulator set the reverse direction on creation.
This enables a simulator to be aware of the direction.
* Add a drive_motor plugin.
This is a bit of a 'magic' motor, which allows us to build robot
models that drive in a more realistic fashion. It does this
by apply forces directly to the chassis, rather than relying on
the complex motion dynamics of a driven wheel.
This in turn allows the model to reduce wheel friction,
reducing scrub, and allowing for a more natural driving experience.
Making Travis run wpilibj_frcnetcomm.py will help avoid bitrot in
FRCNetComm.java in the future. Formatting was also enabled on Python
source files and FRCNetComm.java was added back to the generated files
list.
