-------------------------
Summary: Handling empty ChannelExec#getInvertedOut() to rely on
InputStream
Key: SSHD-1302
URL: https://issues.apache.org/jira/browse/SSHD-1302
Project: MINA SSHD
Issue Type: Improvement
Affects Versions: 2.9.1
Environment: Java 8
Reporter: dgü
Hello!
If I read an input stream until end of it, and then read it again, it throws an
exception.
Here is the test case:
{code:java}
BufferedReader input;
String line;
//process.getInputStream() gets its value from
ChannelExec#getInvertedOut()
System.out.println("getInputStream: " + process.getInputStream());
input = new BufferedReader(new
InputStreamReader(process.getInputStream()));
while ((line = input.readLine()) != null) {
System.out.println(line);
}
System.out.println("getInputStream: " + process.getInputStream());
input = new BufferedReader(new
InputStreamReader(process.getInputStream()));
while ((line = input.readLine()) != null) {
System.out.println(line);
}
{code}
Here is an output excerpt:
{quote}getInputStream:
org.apache.sshd.common.channel.ChannelPipedInputStream@bd8db5a

It looks the input stream is closed.
is it possible not to throw an exception to rely on java.io.InputStream ?
Thanks in advance...
