min yun law commented on SSHD-1085:
-----------------------------------
also with the 2.6.0, I have problem for the command "unzip -l
big_zip_file_with_lots_files_folders.zip", when read the channel output, it
will get stuck and finally return error:
Pipe closed after 0 cycles
for smaller zip file, the "unzip -l" can list and return all files/folder
content back.
So look like channel in 2.6.0 has issue to handle big return content.
> channel.waitFor() get stuck when run reboot command

> Key: SSHD-1085
> URL: https://issues.apache.org/jira/browse/SSHD-1085
> Project: MINA SSHD
> Issue Type: Bug
> Affects Versions: 2.5.1
> Environment: linux
> Reporter: min yun law
> Assignee: Lyor Goldstein
> Priority: Major
>
> Trying to run linux command "reboot" by mina sshd to remote node, the node is
> in reboot, but the ClientChannel object still keep open, not in closed
> status, Here is the logic code in my project:
>
> {code:java}
> String command = "reboot";
> ChannelExec channel = clientSession.createExecChannel(command);
> if(!channel.isClosed())
> {
> ByteArrayOutputStream out = new ByteArrayOutputStream();
> ByteArrayOutputStream err = new ByteArrayOutputStream(); channel.setOut(out);
> channel.setErr(err);
> channel.open().await(); //this passed
> //follow call will cause stuck
> Collection<ClientChannelEvent> waitMask =
> channel.waitFor(REMOTE_COMMAND_WAIT_EVENTS, 0L);
> String outputStr = new String(out.toByteArray(), StandardCharsets.UTF_8);
> //some case this will throw runtime exception
> int exitStatus = channel.getExitStatus();
> }
>
> {code}
>
> So why the ChannelExec cannot get the correct channel status when remote node
> is rebooting?
