Subject [jira] [Commented] (SSHD-108) Add upload monitoring to sftp

Shashank commented on SSHD-108:
-------------------------------

Hi [~lgoldstein],

Thanks for you time.

I did further analysis on this and observed that in Nio2Session (startReading() and startWriting()
methods) whenever a session gets closed in middle of a transfer, IOException (An existing
connection was forcibly closed by the remote host) is being raised and onFailed() is being
invoked.

In this particular case, by having a new boolean variable in Nio2Session to indicate transfer
abort. Something similar to isClosing() and isClosed() mehtods. Could you please provide your
thoughts on this?

> We have sshd integrated into our application and sftp is working fine.  One of the requirements
is to initiate some action when a file upload it complete.  I have made this work by implementing
handleClose in my SshFile implementation and performing the action if createOutputStream had
been called previously.  This seems a bit ugly though; it might be nicer if there was some
plug in mechanism to monitor file transfers.
> Ideally the monitor would be able to distinguish between a successful upload and a cancelled
one (via ctrl-c at the client), but a quick perusal of the sftp stuff seems to inidicate that
this is not possible.
