Testcases in this directory require zzuf and socat.
|
||||
|
||||
zzuf is used to randomly mess with the TCP connection between the CURL
|
||||
clients and the MHD server. The goal is to expose problems in MHD's
|
||||
error handling (by introducing random syntax errors). socat is
|
||||
used to listen on port 11081 and forward the randomzied stream to
|
||||
port 11080 where MHD is waiting.
|
||||
|
||||
As a result, the testcases in this directory do NOT check that
|
||||
whatever CURL returns is what was expected -- random modifications to
|
||||
the TCP stream can have random effects ;-). Testcases "fail" if the
|
||||
code crashes or hangs indefinitely.
