Steven Rowe commented on LUCENE-3690:
-------------------------------------
bq. some test docs using malformed markup that require backtracking
I set up a quick test for this in both of the test classes using output from
the synthetic broken HTML generator
{{o.a.l.util._TestUtil.randomHtmlishString()}} and ran 100K iterations of it -
here's the HTMLStripCharFilterTest version:
{code:java}
public void testRandomBrokenHTML() throws Exception {
int maxNumElements = 10000;
String text = _TestUtil.randomHtmlishString(random, maxNumElements);
Reader reader
= new HTMLStripCharFilter(CharReader.get(new StringReader(text)));
while (reader.read() != -1);
}
{code}
Best/worst of 5 (as reported by Ant for the individual test, rather than for
the entire Ant invocation):
* {{HTMLStripCharFilter}}: best: 73.4 sec, worst: 76.5 sec
* {{JFlexHTMLStripCharFilter}}: best: 73.5 sec, worst: 76.0 sec
I'm going to increase the evilness of {{_TestUtil.randomHtmlishString()}} and
re-run to see if the numbers shift.
