7c1a7332e1 uv::Async, uv::AsyncFunction: allow calling from within loop 2018-10-16 09:40:59 -07:00

172e438cd6 wpiutil: uv::Async: Keep weak reference to loop 
Other handles can only be used within the loop itself, but Async is intended
to be used from another thread.  This introduces the possibility of a race
condition between the loop being destroyed and the Async being destroyed.
Change Async to keep a weak reference to a loop and check it before performing
libuv operations.

1a7a0db1ff wpiutil: Change uv::AsyncFunction to use promise/future. 
This allows the called function to pass along the promise to another
asynchronous callback.

To avoid memory allocations, add a home-rolled, simplified, non-allocating
version of std::promise and std::future as wpi::promise and wpi::future.

8b1274d744 Replace typedefs in C++ with using declarations (#1339)

26c33a9a56 Remove priority_condition_variable (#1337) 
Make wpi::condition_variable typedef to std::condition_variable_any if
wpi::mutex typedefs to priority_mutex.

priority_condition_variable was originally intended as a copy of
std::condition_variable_any that also returned the internal handle like
std::condition_variable. This was needed because NetComm required a
pthread_cond_t. We no longer use it anywhere.

Its args were specialized for priority_mutex, but
std::condition_variable_any supports this and more through
templatization.

1de1900dbb Change uv::Async to accept data parameters 
This is a breaking change as it makes Async a template (e.g. Async<> must
be used instead of just Async).  When data parameters are provided, an
internal mutex and vector is used to hold the parameter packs until the loop
runs.

0e9172f9a7 Fix many errorprone warnings (#1247) 
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()

00c2cd7dab Improve JNI loading efficiency (#1224) 
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.
