[jira] Created: (XMLBEANS-209) Saver$TextSaver.replace method throws java.lang.ArrayIndexOutOfBoundsException

Saver$TextSaver.replace method throws java.lang.ArrayIndexOutOfBoundsException
------------------------------------------------------------------------------

         Key: XMLBEANS-209
         URL: http://issues.apache.org/jira/browse/XMLBEANS-209
     Project: XMLBeans
        Type: Bug
    Versions: Version 2    
 Environment: Java2 RE 1.4 and Java2 RE 5.0
    Reporter: Koyama Hiroshi


Stacktrace is as follows.
java.lang.ArrayIndexOutOfBoundsException
        at java.lang.System.arraycopy(Native Method)
        at org.apache.xmlbeans.impl.store.Saver$TextSaver.replace(Saver.java:1438)
        at org.apache.xmlbeans.impl.store.Saver$TextSaver.entitizeContent(Saver.java:1269)
(snip)

I checked each variables.
1438:    System.arraycopy( _buf, i, _buf, i + dCch, _in - i );  // i:16358 _in:16381 dcCh:4 _buf.length:16384

I think _buf has not enough size.
So, I changed source as follows. 
1438:    if (_buf.length < _in+dCch+_in-i)  i = resize( dCch, i);
1439:    System.arraycopy( _buf, i, _buf, i + dCch, _in - i );

This is not good patch, but I can save xml data.

regards.

[jira] Updated: (XMLBEANS-209) Saver$TextSaver.replace method throws java.lang.ArrayIndexOutOfBoundsException

Posted by "Wei Yin Teo (JIRA)" <xm...@xml.apache.org>.
     [ http://issues.apache.org/jira/browse/XMLBEANS-209?page=all ]

Wei Yin Teo updated XMLBEANS-209:
---------------------------------

    Attachment: saver.patch

This happen when a char that is replaced is near the end of the circular buffer, e.g. '&' at i = 16381, _in = 16382, _buf.length = 16384, dCch = 4, replacement = '&amp;'.  System.arraycopy is called with destination index at  'i+dCch' = 16385 which is greater than the buffer length.

Special care must be taken care when the replacement will wrap around the buffer.

Please see the attach diff for the fixes.

[jira] Commented: (XMLBEANS-209) Saver$TextSaver.replace method throws java.lang.ArrayIndexOutOfBoundsException

Posted by "Peter Rodgers (JIRA)" <xm...@xml.apache.org>.
    [ http://issues.apache.org/jira/browse/XMLBEANS-209?page=comments#action_12414243 ] 

Peter Rodgers commented on XMLBEANS-209:
----------------------------------------

This bug occurs whenever entity expansion occurs on or near the circular buffer boundary.  Try serializing something like...

<root>&amp;...repeat 4096 times...</root>

The circular buffer wraps and starts to write to the start of the buffer overwriting any previously serialized data and making the serialization unparseable.  Here is a fix which now detects the buffer wrap around situation and expands the buffer.  It is a little more efficient than the suggested patch above.

Below is a new else statement found at line 1460 of replace() method in Saver.java  The old code is commented out and retained for reference.

else
{
                assert i < _in;
                int availableEndChunk = _buf.length - _in;
				
		/*PJR Removed Bug
                if ( dCch < availableEndChunk )
                {
                    System.arraycopy( _buf, i, _buf, i + dCch, _in - i );
                    _in += dCch;
                }
                else
                {
		    //PJR Bug is here!
		    int numToCopyToStart = _in - i - availableEndChunk;
                    System.arraycopy( _buf, _in-numToCopyToStart, _buf, 0, numToCopyToStart );
                    System.arraycopy( _buf, i, _buf, i+dCch, availableEndChunk );

                    _in = numToCopyToStart;					
                }
		*/
				
		//PJR fixed version
		if( dCch >= availableEndChunk)
		{	//Grow the buffer
			i=resize(availableEndChunk+1, i);
		}
		//PJR Shove stuff along.
		System.arraycopy( _buf, i, _buf, i + dCch, _in - i );
		_in += dCch;
}

[jira] Commented: (XMLBEANS-209) Saver$TextSaver.replace method throws java.lang.ArrayIndexOutOfBoundsException

Posted by "Yana Kadiyska (JIRA)" <xm...@xml.apache.org>.

----------------------------------------

Thanks a lot -- is it possible for you to provide the schema and instance corresponding to the ManuscriptDocument? I realize that they might be proprietary and if so that's fine. My concern is that there might be a bigger issue at hand than just the buffer size and I'd like to try debugging that code before incorporating your suggested fix (which might well be correct and sufficient)

Thanks

-----------------------------------------

It is as follows. org.sssg.schema.ManuscriptDocument class is generated by XMLBeans.
doc.save(os); throws Exception.
ManuscriptDocument has base64 data, but I do not know whether it is influential. 

---------------------------------------------------------------------------------------------------
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStreamWriter;

import org.sssg.schema.ManuscriptDocument;

import org.apache.xmlbeans.XmlException;

public class Sample {
	private ManuscriptDocument doc;
	public void save(String fileName) {
		OutputStreamWriter os = null;
		try {
			os = new OutputStreamWriter(new FileOutputStream(fileName),"UTF-8");
			doc.save(os);
			os.flush();
		} catch (IOException e) {
			System.out.println("write error");
		} finally {
			if (os != null) {
				try {
					os.close();
				} catch (IOException e) {
					System.out.println("can't close "+fileName);
				}
			}
		}
	}
	public void importXml(String fileName) {
		doc = null;
		try {
			doc = ManuscriptDocument.Factory.parse(new File(fileName));
		} catch (IOException e) {
			System.out.println("can't find "+fileName);
		} catch (XmlException e) {
			System.out.println("XML syntax error : "+fileName);
		}
	}
	public static void main(String args[]) {
		Sample list = new Sample();
		list.importXml("sample.xml");
		list.save("saved.xml");
	}
}
