|
+In fact, the datagrams are received. The problem in this test case is
|
|
+the race condition between the async delegate performing the
|
|
+ReceiveFrom(), and the loop polling and creating a new buffer:
|
|
+
|
|
+Poll() says that data is there to be read
|
|
+A new buffer is created
|
|
+A new async thread is launched to read data into this buffer
|
|
+Poll() says that data is still there
|
|
+A new buffer is created
|
|
+The async thread reads the data into the old buffer
|
|
+The async thread calls the callback, which looks in the new buffer and
|
|
+doesn't find anything.
