[jira] Commented: (XERCESC-1354) Parallel parsing with validation
[ http://issues.apache.org/jira/browse/XERCESC-1354?page=comments#action_60358 ]
mind commented on XERCESC-1354:
-------------------------------
This is hard to repeat. I tried writing short program, but with no results. I'll do this, but it will take some time..
> Parallel parsing with validation
> --------------------------------
>
> Key: XERCESC-1354
> URL: http://issues.apache.org/jira/browse/XERCESC-1354
> Project: Xerces-C++
> Type: Bug
> Components: Validating Parser (Schema) (Xerces 1.5 or up only)
> Versions: 2.5.0
> Environment: Linux SMP
> Reporter: mind
>
> I do following:
> 1. Create xercesx::XMLGrammarPoolImpl (including xercesc/internal/XMLGrammarPoolImpl.hpp)
> 2. Create 2 parsers, setting this one pool for both:
> new SAXParser(0,XMLPlatformUtils::fgMemoryManager,getGrammarPool())
> 3. Load grammar, turn on validation
> 4. fork
> 5. Do parallel parsing on 2 processors
> 6. Enjoy following backtrace:
