varnishtest "cannot add the HTX EOM block because the buffer is full"
feature ignore_unknown_macro

#REQUIRE_VERSION_BELOW=2.4
#REGTEST_TYPE=devel

# This test checks that an HTTP message is properly processed when we failed to
# add the HTX EOM block in an HTX message during the parsing because the buffer
# is full. Some space must be released in the buffer to make it possible. This
# requires an extra pass in the H1 multiplexer. Here, we must be sure the mux is
# called while there is no more incoming data.
