Starting to add Getters, Setters, and Allocators to the C interface
Because of the union in the NT_Value structure, some languages would
have a difficult time with the interop. This commit adds individual
getters and setters to the C interface to make interop easier.
In addition, some languages cannot allocate native memory in the same
heap that the C code would use. This adds allocation functions to make
sure that all our memory is allocated and can be freed properly from the
same heap.
The reason the getters are not individual get functions are because that
would require the calling code to first get the type, and then call the
specific getter for that type. Doing combined get functions causes
interop code to only have to cross interop boundaries once to get the
value instead of twice, for a light performance increase. However, this
could be changed without much work.
NT getters and setters round 2
Fixed some of the code based on the comments in the pull request.
Creates individual getters.
Should work better then 1 single getter.
Fixes end of file new line, and fixes function nameing
SetNTValue... made less sense then SetEntry... Matches the getter
naming.
Fixed methods to be less leaky.
Fixed Formatting, Fixed return values on Bool and Double. Added Contains Key
Changed ContainsKey to GetType. Also renamed Arr to Array
In public functions, I think I like Array better then Arr. Also, make
the getters that use value check for a null value, which should prevent
segfaults.
Fixes C++ Type functions to work properly
NTString Set functions still do not work properly though. I need some
help on there. Error message is in the pull request.
Changes Get functions to return status and have pointer to data passed in to be set.
Fixes NT_Strings
Added new functions to ntcore.def
Fixes NT_PostRpcResponse in the def file
Was NT_PostRpcRepsonse, which was failing the build.
Removed unused parameter from setters
Since we were forcing exports in the cmake build, they were seen in
windows, but since the header didnt match the implementation they
wouldn't export on linux. So fixed that. Linux builds now work properly,
tested on a physical RIO.
Added a DisposeEntryInfoArray method.
There was no way to free the array returned from GetEntryInfo
Adds NT_DisposeEntryInfoArray to the def file.
Implement automatic persistent saves.
Also loads persistent file on server start.
Update TODO.
raw_istream and kin: a few cleanups.
anchor() doesn't seem to change compiler output in current compilers, so
remove it. Use default where appropriate rather than empty bodies.
Clean up trailing whitespace.
Dispatcher: Move several fixed initial values to header.
Uninline constructors to reduce GetInstance() inlined code size.
Logger: Move m_min_level init to header.
Replaced time.h with std::chrono
This implementation returns the same values as the previous one on both a Linux machine and the roboRIO.
Value: Use variant of enable_if to fix MakeString/MakeRaw in GCC.
Tested on GCC 4.8, GCC 4.9, and clang 3.6.
Don't dispose in ConvertToC for NT_String and NT_Value.
Fixes#16.
Fixed Gradle build to actually export proper functions
Finishes fixes in pull request
Changes array setters to be const
To build RPC, needed a way to allocate a Char Array
Since after the callback, the C code explicitly frees, a way to make
sure to allocate the callback return string from the same heap was
needed.
Adds const to NTString setters.
Removes Const from NTString setters
Also only perform immediate notification to the callback actually
requesting the notification, not all existing callbacks.
Offset returned uids by 1 so uid=0 can be used to indicate immediate
notification.
Windows returns WSAEWOULDBLOCK on a connect() attempt on a nonblocking socket.
Also wrap socket error handling so errors are correctly reported on Windows.
Fixes#19.
- Missing header file callouts in some cases (library deltas)
- Lack of support for auto parameters in lambdas
- Defining of ERROR by windows.h
- Dispatcher::Connection needs a move constructor (default not generated)
- Need explicit enable_if on std::string move template in Value to avoid trying to move const char[] (string literal)
- Compile flags
This makes it difficult to test. Instead, store reference as member variable,
and populate it at constuction (with an alternate constructor available for
test purposes).
