Description Mikel Garai 2010-01-12 11:17:28 UTC

In code like this:

cat XXX | ( while read a b c; do
   echo $a
   echo $b
  ....
done )

the current implementation leads to a infinite loop.

The patch attached in the bug 865 ( https://bugs.busybox.net/show_bug.cgi?id=865 ) fixes this bug.

I propose adapting and reusing (sharing) ash's readcmd() code. It is a bit more work, but ash's read is well debugged and supports options like timeouts, max chars and so on.

Fix is committed to git.
