Zhenliang Su commented on SSHD-814:
-----------------------------------
Thanks.
1. Yes, there are no such SFTP command 'upload/download'. There are some
situation that do something after downloading or uploading. For now, my way to
approach this is doing something in `close` callback function and judge whether
the file which closing is called `read/written` callback function. Is there
some else way to do this?
2. When do a delete or rename or other action to a non-exist file or directory.
For now, it just open failed, and not call any callback function in
`SftpEventListener`.
My testing code is the middleman code in
https://issues.apache.org/jira/browse/SSHD-812 .
My steps are:
1. Use filezilla sftp to the middleman, and see a list of file of the target
server.
2. Ssh to the target server, delete a file.
3. Not refresh a filezilla, now you can still see the file which deleted just
now.
4. Download that file.

> Issue Type: Improvement
> Affects Versions: 1.7.0
> Reporter: Zhenliang Su
> Assignee: Goldstein Lyor
> Priority: Minor
> Labels: EventListener, sftp
>
> In practice, I found that, the callback function provided by
> SftpEventListener is not enough. For example, the following situation is not
> easy to be notified in a elegant way:
> {code:java}
> download files that you do not have access to
> download a file that no longer exists
> upload files to a directory without permissions
> create a new file in a directory that you do not have access to
> download or upload a file complete
> upload a zero size file
> ...{code}
