-----------------------------------
Summary: SFTP client fails to retrieve a binary file using an
InputStream
Key: SSHD-765
URL: https://issues.apache.org/jira/browse/SSHD-765
Project: MINA SSHD
Issue Type: Bug
Affects Versions: 1.6.0
Reporter: Michael Binder
The SFTP client fails to retrieve a binary file from an SFTP server using the
InputStream returned by the {{SftpClient.read (String)}} method.
In my case the binary file was actually a gzipped XML file. So I wrapped the
returned InputStream in a {{java.util.zip.GZIPInputStream}} object. When
reading from the stream I received an IOException with following message:
"org.apache.sshd.client.subsystem.sftp.SftpInputStreamWithChannel.read()
returned value out of range -1..255: -117".
I think that this method violates the contract given in
{{java.io.InputStream}}: "The value byte is returned as an int in the range 0
to 255. If no byte is available because the end of the stream has been reached,
the value -1 is returned."
After I patched line 131 in SftpInputStreamWithChannel.java to
{code:java}
return bb[0] & 0xFF;
{code}
retrieving the file seemed to have worked fine.
