Github user oknet commented on the issue:
https://github.com/apache/trafficserver/pull/701
@jpeach VC_EVENT_EOS indicates socket fd is closed. VC_EVENT_ERROR means
meet a error and can not going on. Looking around the comment on
I_VConnection.h about do_io_read and do_io_write. VC_EVENT_EOS is not
introduced in do_io_write, only VC_EVENT_ERROR.
Is VC_EVENT_EOS callbacked only do_io_read first ?
Write to a closed fd then get -EPIPE and VC_EVENT_ERROR callbacked, is it
right ?
