Subject [jira] [Commented] (SSHD-626) ssh scp command is broken on mina backend
Date Tue, 16 Feb 2016 15:04:18 GMT

    [ https://issues.apache.org/jira/browse/SSHD-626?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15148767#comment-15148767
] 

Hugo Arès commented on SSHD-626:
--------------------------------

I tracked it down hoping that the information I gave would ring a bell to someone from this
project. I can upload a revert patch but it feels like going backward. The intention of the
author was clearly to reuse incoming buffer for the outgoing response. Because of my lack
of knowledge in this project, I cannot tell if it is safe to reuse incoming buffer in AbstractChannel
which would mean that there is a bug in Mina since the same code works with NIO2.

I will try spend more time on this issue soon but in the meantime, I will upload a revert
patch.
