Would throw if the camera was disconnected. We handle this properly at
the JNI level to not have this crash the entire program, but the error
is still kind of annoying, and not really an error.
Unfortunately, due to the way NT synchronization is currently performed,
this has unexpected and undesirable behavior: when a dashboard (or any other
NT client) is left running between code restarts, when it reconnects, any
code settings will be overwritten by the NT synchronization process. As
fixing this will require a fairly major NT change (and likely a user-visible
one), it's not desirable to do at this point in the year.
Instead, disable NT driven settings entirely (e.g. make the NT interface
publish only). To emphasize the read-only nature of the NT values, attempts
to change the NT values will be immediately overridden by CameraServer.
To better inform users about the actual property names (e.g. for use in their
code), the "raw_" settings no longer have "raw_" removed from their names
(they are still placed in the "RawProperty" subtable).
This change also contains a couple of Java fixes:
* Make getInstance() thread-safe
* Properly synchronize access to m_tables between multiple threads.
* Use Hashtable instead of HashMap.
* Java SendableChooser now decorates with type (non-breaking change)
* C++ SendableChooser now is templated on the type instead of using void* and stores values (breaking change)
* C++ SendableChooser now uses llvm::StringMap instead of std::map
The current LabVIEW dashboard (Beta 4) requires the source type to be either
"usb:" or "ip:" and does not support "cv:". To work around this, use a source
type of "usb:" for OpenCV sources as well.
Workaround for #407.
Also adds Java API for doing the same to Java threads (standard Java Thread.setPriority only works
when Java is run as root, even if the process has the right privileges).
This makes our APIs more consistent. With optimizations enabled, doubles are just as efficient as floats on ARMv7, so we should take advantage of the extra precision.
* Links HAL shared instead of static, and doesn't include library in jar
* Strips shared object files, and includes debug in releases
* Zips the HAL libraries into a separate maven artifact
* Switches to shared wpiutil
* Switches wpilibc to shared
* Moves maven artifacts
wpilibc now in edu.wpi.first.wpilibc:athena
wpilibj now in edu.wpi.first.wpilibj:athena
wpilibj jni not in edu.wpi.first.wpilibj:athena-jni
hal now in edu.wpi.first.wpilib:hal
athena runtime added (hal, ntcore, wpiutil) edu.wpi.first.wpilib:athena-runtime
Changes made where wpilibc does NOT include all required artifacts anymore. Dependent on hal, wpiutil and ntcore packages to work correctly.
JNI does NOT include all required artifacts anymore. Dependent on hal and wpiutil packages to work correctly.
