[contrib #676] infinit loop in scala.xml.PrettyPrinter |
| code |
import scala.xml._;
object PrettyPrint extends Application {
override def main(args : Array[String]) {
val x = <td align="center" colspan="1" nowrap="nowrap" rowspan="1" valign="top" height="25"></td>
println(new PrettyPrinter(79,3).format(x)); // works ok
println(new PrettyPrinter(81,3).format(x)); // works ok
println(new PrettyPrinter(80,3).format(x)); // loops infinitely because xml string hits an edge case with width 80
}
}

| what happened |
third println loops infinitely, eventually getting an OutOfMemoryError
|
| what expected |
should pretty print properly and terminate.
I believe there is a bug in scala.xml.PrettyPrinter.cut()
The loop starting at line 63
while (i < tmp) {
last = i::last
i = s.indexOf(' ', i)
}
is the culprit as s.indexOf(' ',i) will always return i. But I do not know the proper fix as merely changing it to s.indexOf(' ',i+1) is insufficient as eventully i will be -1.
