----------------------------

             Summary: event overwrited by SSL_READ_READY / COMPLETE in ssl_read_from_net
                 Key: TS-4412
                 URL: https://issues.apache.org/jira/browse/TS-4412
             Project: Traffic Server
          Issue Type: Bug
          Components: SSL
            Reporter: Oknet Xu


the {{ssl_read_from_net}} read data from socket and saved into MIOBuffer.

It was designed to fill the MIOBuffer as much as possible, even execeed the VIO {{nbytes}} setting.

It will try to call {{SSLReadBuffer}} again and again until the MIOBuffer is full or an error returned from {{SSLReadBuffer}}. The {{event}} will be set to a error status if an error returned from {{SSLReadBuffer}}.

But at the end of {{ssl_read_from_net}}, the {{event}} will be overwrited to SSL_READ_READY or SSL_READ_COMPLETE depend on {{vio.ntodo()}} if this is one success at least in {{SSLReadBuffer}} before an error.

For example:
    The {{SSLNetVConnection::net_read_io}} could not get SSL_READ_EOS from {{ssl_read_from_net}} and can not close the SSLNetVConnection immediately. Because The {{event}} SSL_READ_EOS is overwrited.
    The SSLNetVConnection will be closed by timeout.
