Some possible contribution tasks

1. More substitutes for Future callback methods. (project = trackedfuture, level = easy)

• look at Scala Future interface: https://github.com/scala/scala/blob/2.11.x/src/library/scala/concurrent/Future.scala and find method which accept callback and not handled in https://github.com/rssh/trackedfuture/blob/master/agent/src/main/scala/trackedfuture/agent/TFMethodAdapter.scala. Today this can be onSuccess or onFailure
• add an implementation of debugging variant to https://github.com/rssh/trackedfuture/blob/master/agent/src/main/scala/trackedfuture/runtime/TrackedFuture.scala
• add a test (analogically to other tests) in example subproject

2. Write replacement for Await.result / Await.ready which in case of timeout will also show the state of the Future in Await argument if this is possible. (project = trackedfuture, level = middle)

• Add to StackTraces field with current future, which will set on change of thread boundaries.
• add setting of such field during the creation of appropriate thread-local
• in ClassVisitor add translator for Await/result & Array/ready
• in translated Await runtime handle timeout exception and in this handler search for currently set Future in Thread-Local of all threads.
• If found - print stacktrace of this thread as additional information.

3. Implement select.timeout (project = scala-gopher, level=expert)

4. Implement lifting async throught hight-order functions (project = scala-gopher, level=expert, size=big )
