std::scoped_lock was introduced in C++17 and is strictly better than
std::lock_guard as it supports locking any number of mutexes safely.
It's also easier to use than std::lock for locking multiple mutexes at
once.
The old headers were moved into folders because doing so avoids polluting
the system include directories.
Folder names were also normalized to lowercase.
LiveWindow.updateValues() is now called from IterativeRobotBase on every
loop iteration. Telemetry for all WPILib classes is enabled by default;
it can be disabled for specific classes using LiveWindow.disableTelemetry(),
or all telemetry can be disabled using LiveWindow.disableAllTelemetry().
This necessitated changing the hook methodology into other classes to
be more property-based rather than each class providing multiple functions.
This had the benefit of reducing boilerplate and increasing consistency.
- Remove NamedSendable, add name to Sendable.
- Provide SendableBase abstract class.
- Deprecate LiveWindow addSensor/addActuator interfaces.
- Add LiveWindow support to drive classes.
- Add addChild() helper functions to Subsystem.
- Fix inheritance hierarchy. Now only sensors inherit from SensorBase.
Other devices inherit from some combination of SendableBase, ErrorBase, or
nothing.
To make this work in PIDController.java, the use of synchronized had to be
replaced with ReentrantLock and try-catch blocks. The locking in
PIDController.java was made equivalent to PIDController.cpp and some existing
race conditions in PIDController.java were fixed in the process.
Fixes#30.
m_pidInput and m_pidOutput are considered constant after their construction.
Setting the input range, output range, tolerance, or continuous mode locks the
controller. m_error and m_result are held in temp variables and set at the end
of the calculation.
Getters of P, I, D, F, m_error, m_setpoint, m_result, and m_enabled lock the
critical section. P, I, D, F, and m_setpoint are retrieved at the beginning of
Calculate().
Fixes#40.
* Removed hal::priority_condition_variable
* Replaced uses of priority mutexes with std::mutex and std::recursive_mutex
This allowed replacing a use of std::condition_variable_any with
std::condition_variable.
* Replaced all uses of std::recursive_mutex with std::mutex equivalents
* Revert "Force OpenCV to 3.1.0 (#602)"
This reverts commit 50ed55e8e2.
* Removes Simulation

* Removes old gtest
* Adds new gmock and gtest
* Updates to new ni-libraries
