"""Test nodes responses to having many blocks in flight.
|
|
|
|
In this test we connect to one node over p2p, send it numerous inv's, and
|
|
compare the resulting number of getdata requests to a max allowed value. We
|
|
test for exceeding 128 blocks in flight, which was the limit an 0.9 client will
|
|
reach. [0.10 clients shouldn't request more than 16 from a single peer.]
