[CLucene-dev] Terms are out of order precondition failing

[Matt R. <mr...@mr...>]

Hi,

I'm just getting started with CLucene and I'm running into a precondition that is failing. I grabbed the latest snapshot from Git (just a day or two ago), here is the error I'm getting:

file:/Users/mronge/Projects/clucene/src/core/CLucene/index/TermInfosWriter.cpp line:161
Terms are out of order: field=body (number 0) lastField=body (number 0) text= lastText=\377x

Here is the precondition:

    CND_PRECONDITION(compareToLastTerm(fieldNumber, termText, termTextLength) < 0 ||
      (isIndex && termTextLength == 0 && lastTermTextLength == 0),
      (string("Terms are out of order: field=") + Misc::toString(fieldInfos->fieldName(fieldNumber)) +
      " (number " + Misc::toString(fieldNumber) + ")" +
      " lastField=" + Misc::toString(fieldInfos->fieldName(lastFieldNumber)) +
      " (number " + Misc::toString(lastFieldNumber) + ")" +
      " text=" + Misc::toString(termText, termTextLength) +
      " lastText=" + Misc::toString(lastTermText.values, lastTermTextLength)
      ).c_str() );

From looking at compareToLastTerm it appears it returns 1 if the length termText is < length of lastTermText, so it fails here when termText is empty. Is this correct? Shouldn't it just return -1 when when termText is empty, since "empty" could be ordered in front of everything else?

Thanks!
Matt

Hi,


Tests are running smooth for me here, but I do recall we had a test 
failing there.


Can you post some code which will allow us to reproduce this?


Itamar.
