---------------------------------
Patch available at SSHD-145
> InvertedShellWrapper won't pump end of stream
> ---------------------------------------------
>
> Key: SSHD-125
> URL: https://issues.apache.org/jira/browse/SSHD-125
> Project: MINA SSHD
> Issue Type: Bug
> Affects Versions: 0.5.0
> Reporter: René Treffer
>
> The "pumpStreams" method (
> http://svn.apache.org/viewvc/mina/sshd/trunk/sshd-core/src/main/java/org/apache/sshd/server/shell/InvertedShellWrapper.java#l89
> ) of InvertedShellWrapper has a loop that won't collect the last output of a
> process.
> The faulty event sequence looks like this:
> 1. process alive? -> yes
> 2. Anything to pump? -> no
> 3. Thread.sleep(1)
> 4. process alive? -> no
> 5. call exit handler and end pump thread
> This will obviously discard any output of the process during step 3 and 4.
> The solution would be to pump all pending output before the exit handler gets
> called (while (pumpStream(shellOut, out, buffer) || pumpStream(shellErr, err,
> buffer)) {}).
