# Start a series of <threads> client threads that each make <batchsize>
|
|
# IPC requests to the server. Each (<threads> * <batchsize>) request
|
|
# will open a new connection to the server and randomly bind to a server
|
|
# thread. Each client thread exits after completing its batch. So the
|
|
# total number of live client threads will be smaller than the total.
|
|
# Each request will send a message containing at least <bytecount> bytes
|
|
# of ballast. (Responses are small.)
|
|
#
|
|
# The purpose here is to test threading in the server and responding to
|
|
# many concurrent client requests (regardless of whether they come from
|
|
# 1 client process or many). And to test that the server side of the
|
|
# named pipe/socket is stable. (On Windows this means that the server
|
|
# pipe is properly recycled.)
|
|
#
|
|
# On Windows it also lets us adjust the connection timeout in the
|
|
# `ipc_client_send_command()`.
|
|
#
|
|
# Note it is easy to drive the system into failure by requesting an
|
|
# insane number of threads on client or server and/or increasing the
|
|
# per-thread batchsize or the per-request bytecount (ballast).
|
|
# On Windows these failures look like "pipe is busy" errors.
|
|
# So I've chosen fairly conservative values for now.
|
|
#
|
|
# We expect output of the form "sent:<letter><length> ..."
|
|
# With terms (7, 19, 13) we expect:
|
|
# <letter> in [A-G]
|
|
# <length> in [19+0 .. 19+(13-1)]
|
|
# and (7 * 13) successful responses.
