Robert Muir added a comment - 24/Mar/12 21:35 thanks! let's just hope mike doesn't notice -reproducibility policeman

Steve Rowe added a comment - 24/Mar/12 21:27 I don't think it will be interesting, instead just make seeds less reproducible across java 6 and 7 or other jre impls with different # of locales Hmm, I didn't think of the reproducibility angle. I'll fix. Committed to trunk and branch_3x. Thanks again Robert!

Steve Rowe added a comment - 24/Mar/12 20:24 I think the toUpperCase/toLowerCase in recaseCodePoints should take Locale.ENGLISH? Yeah, I had that in at first, but then I thought it might be useful to use the randomized locale to trigger "interesting things". That's what we want, right?

Robert Muir added a comment - 24/Mar/12 20:21 Thank you! I think the toUpperCase/toLowerCase in recaseCodePoints should take Locale.ENGLISH? Otherwise you will find this gives interesting things for <script> in the Turkish Locale

Michael McCandless added a comment - 24/Mar/12 20:08 Awesome, thanks Steve!

Steve Rowe added a comment - 24/Mar/12 20:06 ant test -Dtestcase=HTMLStripCharFilterTest -Dtestmethod=null ... Actually, I ran it without -Dtestmethod=null .

Steve Rowe added a comment - 24/Mar/12 20:00 - edited Patch, a superset of Mike's: fixes the identified problem: </br> offset was improperly calculated. (Added comments describing the offset calculations everywhere they're performed in the .jflex source.) adds a new case emitting <\s*(/\s*)?(br|script|style)>? to _TestUtil.randomHtmlishString() , because <br>, <script>, and <style> are handled specially in HTMLStripCharFilter. adds a new method _TestUtil.randomlyRecaseCodePoints() , used by the above-mentioned new randomHtmlishString() case, to produce things like <Br> , </sCriPT> , etc. switches HTMLStripCharFilterTest.testRandomBrokenHTML() to use Mike's new BaseTokenStreamTestCase.checkAnalysisConsistency() . fixes the Jenkins test failure of HTMLStripCharFilterTest.testRandomHugeStrings() at https://builds.apache.org/job/Lucene-Solr-tests-only-3.x/12863/ : ant test -Dtestcase=HTMLStripCharFilterTest -Dtestmethod=null -Dtests.seed=48bbf57c15b7aa2d:5bb640584c81078d:-7e916259eafd7e54 -Dtests.multiplier=5 -Dargs="-Dfile.encoding=ISO8859-1" Committing shortly.

Steve Rowe added a comment - 24/Mar/12 15:30 Since we know those are special, a good idea for the future could be to add both those elements to randomHtmlishString +1

Steve Rowe added a comment - 24/Mar/12 15:19 Minimal test failure trigger appears to be "x</br>", where "x" can be any non-whitespace character, and "</br>" must be "</br>". (No problems with "x<br>", "x</a>", etc.) <br> and </br> are handled specially, so this should narrow it down.

Steve Rowe added a comment - 24/Mar/12 14:56 I can reproduce - I'm digging.

Michael McCandless added a comment - 24/Mar/12 14:48 Good idea! I'll fix that test case.

Robert Muir added a comment - 24/Mar/12 14:37 I like the refactored method: though I think we should also call it from HTMLStripCharFilterTest.testRandomBrokenHTML? Currently this only does: while (reader.read() != -1);

Michael McCandless added a comment - 24/Mar/12 14:33 I forgot to say: patch is against 3.x.

Michael McCandless added a comment - 24/Mar/12 14:31 Patch showing the failure.... It happens on input " Secretary)</br> [[M", in case anyone can see something obviously interesting I have no idea where the bug is...
