put() for a computing map violates linearizability #527

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
The specified behavior of MapMaker puts during computation was:

"If Map.put(K, V) is called before a computation completes, other threads 
waiting on the computation will wake up and return the stored value. When the 
computation completes, its new result will overwrite the value that was put in 
the map manually."

This definition violates the principle of linearizability.

We've fixed this and fixed the doc.
