# test gRPC like requests that do not end, but give answers, see #207

# this test works like this:
|
|
# - use curl to POST data to the server /h2test/echo
|
|
# - feed curl the data in chunks, wait a bit between chunks
|
|
# - since some buffering on curl's stdout to Python is involved,
|
|
# we will see the response data only at the end.
|
|
# - therefore, we enable tracing with timestamps in curl on stderr
|
|
# and see when the response chunks arrive
|
|
# - if the server sends the incoming data chunks back right away,
|
|
# as it should, we see receiving timestamps separated roughly by the
|
|
# wait time between sends.
