[jira] Created: (XERCESC-1511) SAX2 parse method starts parsing XML document and hangs
SAX2 parse method starts parsing XML document and hangs
-------------------------------------------------------
Key: XERCESC-1511
URL: http://issues.apache.org/jira/browse/XERCESC-1511
Project: Xerces-C++
Type: Bug
Components: SAX/SAX2
Versions: 2.5.0
Environment: Xerces-C++ version number :- xerces-c_2_5_0-hpux_11-acc_a03
Platform :- HP-UX 11
Operating system and version number :- HP-UX Unix Version 11.0
Compiler and version number :- aCC compiler - HP aC++ Version A.03.37
Reporter: Sunil Ramchandra
Priority: Blocker
Xerces-C++ version number xerces-c_2_5_0-hpux_11-acc_a03
Platform HP-UX 11
Operating system and version number HP-UX Unix Version 11.0
Compiler and version number aCC compiler - HP aC++ Version A.03.37
The schema document has no issues and the the XML string also has no issues, because both work well when i used ALTOVA tool for parsing.
The XML document (or excerpt) that failed
<?xml version="1.0" encoding="UTF-8"?><NumberManagerXML2.0 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="/opt/lnpsite/nimnm00/flat/schema/NMXMLInterface.xsd"><CreateSV><RequestHandleInfo RequestHandle="1319"></RequestHandleInfo><TnInfo

The C++ application code that failed
parser = (SAX2XMLReader*) XMLReaderFactory::createXMLReader();
parser->setContentHandler(this);
parser->setErrorHandler(this);
parser->setFeature(XMLUni::fgXercesSchema, true);
ofstream outfile;
RWCString msgFileName;
RWCString uniqName(tempnam("/tmp","XML_"));
msgFileName.append(uniqName);
msgFileName.append(LTime::now().asString("_%Y""%m""%d",RWZone::utc()));
msgFileName.append(LTime::now().asString("%H""%M""%S",RWZone::utc()));
msgFileName.append(".xml");
outfile.open (msgFileName, ofstream::out); ----> I am creating a temporary xml file here
outfile<<XMLStringBuffer; ---> This string buffer has the XML string mentioned above
outfile.close();
cout<<"I am here: abt to errorReset"<<endl;
this->resetErrors();
cout<<"I am here: abt to parse"<<msgFileName<<endl;
parser->parse(msgFileName); --> Sending the file to the parser (After this i am able to see the start document method call in my logs, but after that nothing)
cout<<"I am here: Done with parse - going to remove file"<<msgFileName<<endl;
remove(msgFileName); --> i am removing the file
Whether you built the Xerces-C++ library yourself or used the binary distribution - NO I sued the 2_5_7 libraries.
What happened
I am using the SAX2 parser to parse my XML files.
I dont use any threads here, its a single flow of events from parser creation till the parsing of the xml file.
I observe that in my logs, once the XML string is created and sent to the piece of code mentioned above. The parser hangs in the parse method.
As per its behaviour, it is supposed to call the "start document" "statrt element" functions whihc are overloaded in my classes.
The last log statement that i see is the " start document " after that i dont get anything. My application proceeds with other threads where i do socket operations totally un-related to the XML logic or piece of code.
Here are the logs

-------------------------------------------
Hi Jesse,
I could not reproduce this issue with the SAX2Print sample application.
Can you help me out, i am not able to proceed with this issue. I have put as many debig statements as possible, but when i run my application its just stops at the "start document" phase of parsing.
Appreciate your reply asap. Thanks
Thanks
SUnil

[jira] Commented: (XERCESC-1511) SAX2 parse method starts parsing XML document and hangs
Posted by "Jesse Pelton (JIRA)" <xe...@xml.apache.org>.

Jesse Pelton commented on XERCESC-1511:
---------------------------------------
If SAX2Print can process your document, the problem is probably not in Xerces. Are you certain that the blocked mutex is not related?
If you parse the memory buffer directly rather than writing it to a file, does the same problem occur?
In any case, it's probably time to break out the debugger. Set a breakpoint in your startDocument() function, then step through the program from there. Your trace indicates that you exit startDocument(), so presumably the problem is elsewhere. With luck, you'll have an "Aha!" moment shortly.
