Uploading file via SFTP leaves file in locked state on Windows
--------------------------------------------------------------
Key: SSHD-97
URL: https://issues.apache.org/jira/browse/SSHD-97
Project: MINA SSHD
Issue Type: Bug
Affects Versions: 0.5.0
Environment: JDK 1.6.0_18 (32bit) running on Win 7 (64 bit). I've a
fairly out-of-the-box Mina SSHD / sftp config. I'm serving from my local
Windows machine.
Reporter: Will Glass-Husain
Uploading a file via SFTP leaves the file in a locked state. Specifically,
when I upload a file using sftpd, the file is locked in windows, even after the
upload is complete.
I verified this by using Yourkit Profiler (see attached screenshots). There
are two writes to the file
* first: NativeSshFile.truncate() erases the old file. This is what fails to
clean up
* second: NativeSshFile.createOutputStream(). This is properly closed after
use.
The fix is simple. In the truncate() method, close the RandomAccessFile after
it is created. See attached patch.
I tested this by putting the truncate method in a subclass of NativeSshFile
and it solved the problem.
After applying the patch to the Mina SSHD source code, I ran "mvn test" which
passed.
