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.
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.
Base.h provides a backwards compatibility shim (enabled unless
NAMESPACED_WPILIB is defined) that does a "using namespace frc".
However, as some header files do not include Base.h, this may
be a breaking change in some corner cases (with an easy fix).
Fixes#218.
Subsections are alphabetized according to lexographic ordering. Also, HAL includes were moved from headers to source files where possible. This change may cause user code which uses HAL functionality and does not include the relevant HAL header (since it may have been provided by another WPILib header) to fail to compile.
Rename the following folders:
hal/lib/Athena -> hal/lib/athena
hal/lib/Desktop -> hal/lib/sim
hal/lib/Shared -> hal/lib/shared
wpilibc/Athena -> wpilibc/athena
wpilibc/simulation -> wpilibc/sim
Windows users may need to run gradlew clean after updating.
