Russ Tennant updated SSHD-725:
------------------------------
Description:
When retrieving files (depending on file size), the files are truncated. We
have also experienced a similar problem on file upload where we get extra data
repeated from the last packet received.
I don't have a test-case for the file upload issue - yet. Still trying to find
the magic file size.
I created a github project that demonstrates the truncation issue on retrieval.
Project: https://github.com/VentureTech/sshd-test
Example lftp Script:
https://github.com/VentureTech/sshd-test/blob/master/download-lftp-script.txt
Example lftp Script Output:
https://github.com/VentureTech/sshd-test/blob/master/download-lftp-script-output.txt
I used lftp to demonstrate the issue, but it happens with all clients I've
tried (openssh, Intellij IDEA, kde's sftp ioslave).
There is a gradle task lftpDownload that will start the server and run the lftp
script.
{code}./gradlew lftpDownload{code}
Attached is the data file I used to trigger the issue.
In the referenced example output lftp terminates the retrieval with the
following
{code}
[116371] 2017-01-16 15:27:32 localhost <--- got a packet, length=120,
type=101(STATUS), id=12
