nadir amra commented on AXISCPP-770:
------------------------------------
There was a problem with XMLParserXerces::next in that it invoked
m_pParser->parseNext(m_ScanToken) even when there may have been nothing to
parse.
I have fixed this (and simplified) and am currently running the test bucket,
but the fix for XMLParserXerces::next is as follows:
OLD CODE:
bool bCanParseMore = false;
while (true)
{
AnyElement* elem = m_Xhandler.getAnyElement();
if (!elem)
{
//Chinthana:check the peek is called or not
if(!m_bPeeked)
bCanParseMore = m_pParser->parseNext(m_ScanToken);
else
{
m_bPeeked = false;
bCanParseMore = true;
}
elem = m_Xhandler.getAnyElement();
}
if (elem)
{
if (!isCharData && (CHARACTER_ELEMENT == elem->m_type))
{ /* ignorable white space */
m_Xhandler.freeElement();
continue;
}
if( m_bPeeked )
m_bPeeked = false;
return elem;
}
else if (AXIS_FAIL == m_Xhandler.getStatus())
return NULL;
else if (!bCanParseMore)
return NULL;
}
NEW CODE:
bool bCanParseMore = true;
AnyElement* elem;
while (bCanParseMore)
{
// See if we have a token to consume
elem = m_Xhandler.getAnyElement();
// Since we have consumed whatever is there, ensure peek flag is set to
false
m_bPeeked = false;
// If we do not have an element, then parse next token; else if
// whitespace, ignore whitespace; else return token
if (!elem)
{
bCanParseMore = m_pParser->parseNext(m_ScanToken);
if (AXIS_FAIL == m_Xhandler.getStatus())
break;
}
else if (!isCharData && (CHARACTER_ELEMENT == elem->m_type))
m_Xhandler.freeElement();
else
return elem;
}
return NULL;
==============================
The fix for XMLParserXerces::peek is as follows:
OLD CODE:
bool bCanParseMore = true;
m_Xhandler.freeElement();
bCanParseMore = m_pParser->parseNext(m_ScanToken);
AnyElement* elem = m_Xhandler.getAnyElement();
while (CHARACTER_ELEMENT == elem->m_type) // we never peek for char data
//hence this is a white space
{ /* ignorable white space */
m_Xhandler.freeElement();
bCanParseMore = m_pParser->parseNext(m_ScanToken);
elem = m_Xhandler.getAnyElement();
}
NEW CODE:
m_Xhandler.freeElement();
AnyElement* elem;
while (m_pParser->parseNext(m_ScanToken))
{
// Attempt to get token
elem = m_Xhandler.getAnyElement();
// we never peek for char data hence this is a white space - ignore
it.
if (elem && CHARACTER_ELEMENT == elem->m_type)
m_Xhandler.freeElement();
else
break;
}

> Key: AXISCPP-770
> URL: http://issues.apache.org/jira/browse/AXISCPP-770
> Project: Axis-C++
> Issue Type: Bug
> Components: Parser Library - Xerces
> Affects Versions: 1.5 Final
> Environment: linux 2.6.11
> Reporter: jose
> Assigned To: nadir amra
>
> The function const AnyElement* XMLParserXerces::next(bool isCharData) of
> XMLParserXerces.cpp crashes on the next line:
> bCanParseMore = m_pParser->parseNext(m_ScanToken);
> I have tested with xerces 2.2 and with xerces 2.6 and the problem continues.
> If I HTTP GET the Web Services List via http://localhost:8080/axis/ the
> parser works fine for the server.wsdd file, but when I
> call the web service example Calculator and the engine tries to parse the
> soap request in process(), then crashes.
> P.D.: Please, migrate to stable xerces 2.6
