             Summary: transferTo function of SftpRemotePathChannel will loop if count parameter is greater than file size
                 Key: SSHD-970
                 URL: https://issues.apache.org/jira/browse/SSHD-970
             Project: MINA SSHD
          Issue Type: Bug
    Affects Versions: 2.4.1
            Reporter: Michele Milesi
         Attachments: SftpRemotePathChannel.patch

The method {{transferTo}} of {{SftpRemotePathChannel}} does not checks {{eof}} condition.
 * The exit condition from the reading loop is that totalRead variable is not less than count parameter.
 * At eof the value the method does not increment the totalRead variable
 * If {{count}} parameter value is greater than source file size the value of {{totalRead}} will never reach the {{count}} value

In order to exit from the loop we need to check the eof condition.

The attached patch contains:
 * A junit test (added to SftpRemotePathChannelTest.java)
 * A simple fix to the exit condition

The problem was found on:
 * 2.4.0 released version
 * current git head
