Summary

0001165: bug in busybox sh version 1.1.2 and would like to know if it has been resolved in the latest version

Description

A signal will be caught once, but any signal following will not be captured. This can be seen by doing the following:

In BusyBox, make a file sleepTest.sh :
#!/bin/sh
sleeping=true
trap "echo got signal" USR1
for try in 1 2 3 4 5; do sleep 1; kill -USR1 $$; echo sent $try signal; done&
sleep 10&
while $sleeping; do
        trap
        if wait %%; then
                echo sleep completed;
                sleeping=false;
        elif [ $? == 127 ]; then
                echo no sleep tonite;
                sleeping=false;
        else
                echo sleep interrupted;
        fi
done
#--- end of file ---

Make it executable and then execute it.

BusyBox 1.1.2 gave the following:
sent 1 signal
got signal
sleep interrupted
sent 2 signal
sent 3 signal
sent 4 signal
sent 5 signal
sleep completed

Correct result:
sent 1 signal
got signal
sleep interrupted
got signal
sent 2 signal
sleep interrupted
got signal
sleep interrupted
sent 3 signal
got signal
sleep interrupted
sent 4 signal
got signal
sent 5 signal
sleep interrupted
sleep completed

I've tried this on other Linux systems with success. And it would make sense, as one writing a signal handling shell script would probably want more than one signal to be captured.
