[jira] Created: (HARMONY-648) Can't read input from the console
Can't read input from the console
---------------------------------
Key: HARMONY-648
URL: http://issues.apache.org/jira/browse/HARMONY-648
Project: Harmony
Type: Bug
Components: Classlib
Environment: Windows XP
Reporter: Sian January
Using the IBM VME and a version of Harmony built today (23rd June 2006), the following simple program fails:
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
public class Main {
public static void main(String[] args) {
BufferedReader br = new BufferedReader (new InputStreamReader(System.in));
try {
String input = br.readLine ();
System.out.println("Hello " + input);
} catch (IOException e) {
e.printStackTrace();
}
}
}
This fails with an IOException - Stack trace below:
java.io.IOException
at org.apache.harmony.luni.platform.OSFileSystem.seek(OSFileSystem.java:99)
at java.io.FileInputStream.available(FileInputStream.java:126)
at java.io.BufferedInputStream.available(BufferedInputStream.java:101)
at java.io.InputStreamReader.read(InputStreamReader.java:392)
at java.io.BufferedReader.fillbuf(BufferedReader.java:108)
at java.io.BufferedReader.readLine(BufferedReader.java:323)
at p.Main.main(Main.java:12)

Tim Ellison commented on HARMONY-648:
-------------------------------------
Ouch! That's a howler -- thanks.
Confirmed as reproducible.
--
For those that care:
The problem appears to be caused by java.io.FileInputStream#available() that lost it's special logic for FD 0 when the code was updated from a native call to Java code (at repo r376689). We need to use platform specific code to determine available() for stdin.
