From bash's manpage: "Background processes which attempt to read from (write to) the terminal are sent a SIGTTIN (SIGTTOU) signal by the terminal driver, which, unless caught, suspends the process." Now I'm wondering how to detect this situation in java-land. When you try to read, you get an IOException: [java] java.io.IOException: Unknown error 512 [java] at java.io.FileInputStream.readBytes(Native Method) [java] at java.io.FileInputStream.read(FileInputStream.java:194) [java] at java.io.BufferedInputStream.fill(BufferedInputStream.java:183) [java] at java.io.BufferedInputStream.read1 (BufferedInputStream.java:222) [java] at java.io.BufferedInputStream.read(BufferedInputStream.java:277) [java] at java.io.FilterInputStream.read(FilterInputStream.java:90) [java] at org.apache.tools.ant.taskdefs.StreamPumper.run(StreamPumper.java:90) [java] at java.lang.Thread.run(Thread.java:534) but how would know if you can read or not? As soon as you attempt to read, you're being stopped SIGTTIN. > question, is, what is doing the read? The sample app isnt, [...] > http://issues.apache.org/bugzilla/show_bug.cgi?id=24918 See the above stacktrace. Java.setupRedirector() sets the inputStream for redirection, where it ends up in a StreamPumper (somewhere in Redirector.createStreams()). The StreamPumper immediately starts reading from the input stream, causing the SIGTTIN. -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
