------- Additional comments from zhangjf...@openoffice.org Thu Aug 5 01:24:36 +0000 2010 ------- The problem is not so serious with normal usages, but it's solution may related with http://www.openoffice.org/issues/show_bug.cgi?id=112783. Please also take a look. To repeat the problem, just simply open any odf document, then save and close it. When saving the odf document, to update some ODF meta data, DOM::CElement::removeChild() is called, so several unoxml dom CNode are removed from the dom tree. Below is the callstack when it happens, unoxmlmi.dll!DOM::CNode::removeChild(const com::sun::star::uno::Reference<com::sun::star::xml::dom::XNode> & oldChild={...}) Line 715 C++ unoxmlmi.dll!DOM::CElement::removeChild(const com::sun::star::uno::Reference<com::sun::star::xml::dom::XNode> & oldChild={...}) Line 274 + 0x11 C++ > sfxmi.dll!`anonymous namespace'::SfxDocumentMetaData::setMetaList(const > char * i_name=0x01ba5154, const com::sun::star::uno::Sequence<rtl::OUString> & i_rValue={...}, const _STL::vector<_STL::vector<_STL::pair<char const *,rtl::OUString>,_STL::allocator<_STL::pair<char const *,rtl::OUString> > >,_STL::allocator<_STL::vector<_STL::pair<char const *,rtl::OUString>,_STL::allocator<_STL::pair<char const *,rtl::OUString> > > > > * i_pAttrs=0x0185b6fc) Line 875 + 0x41 C++ sfxmi.dll!`anonymous namespace'::SfxDocumentMetaData::updateUserDefinedAndAttributes() Line 1056 + 0x16 C++ sfxmi.dll!`anonymous namespace'::SfxDocumentMetaData::serialize(const com::sun::star::uno::Reference<com::sun::star::xml::sax::XDocumentHandler> & i_xHandler={...}, const com::sun::star::uno::Sequence<com::sun::star::beans::StringPair> & i_rNamespaces={...}) Line 2311 + 0xc C++ xomi.dll!SvXMLMetaExport::Export() Line 376 + 0x8e C++ For any UNO XML CNode objects that are not removed from the DOM tree, their corresponding libxml DOM nodes will be completely removed by api xmlFreeDoc(m_aDocPtr) in CDocument::~CDocument(), CDocument::~CDocument(){ ... xmlFreeDoc(m_aDocPtr); } But for any removed Childern CNodes, libxml dom tree doesn't have all these nodes, so in fact all these node will leak after the CDocument object released. DOM::CElement::removeChild() may be also called in other cases, such as calling through UNO API :: com :: sun :: star :: xml :: dom :: XNode::removeChild() directly in OOo applications. Our current ugly fix is to identify all removed Child CNode objects in CDocument dtor api, then for each orphaned CNode, call xmlFreeNodeList(). But it seems this fix conflicts with the fix code of http://www.openoffice.org/issues/show_bug.cgi?id=112783, since CDocument won't remember all child CNode objects any more. --------------------------------------------------------------------- Please do not reply to this automatically generated notification from Issue Tracker.
