Nikolay Sivov : msxml3: Properly update xmldoc refcounts on insertBefore().
Module: wine Branch: master Commit: 0f3c247e46dbc7935bf6e2d563ce16f01cada9ee URL: http://source.winehq.org/git/wine.git/?a=commit;h=0f3c247e46dbc7935bf6e2d563... Author: Nikolay Sivov <nsivov(a)codeweavers.com> Date: Sun Mar 6 22:28:29 2011 +0300 msxml3: Properly update xmldoc refcounts on insertBefore(). insertBefore() is able to work on nodes from different documents, so on adding child or sibling it's possible that libxml2 switches doc pointer for a node, we need to update refcounts to cover that case. --- dlls/msxml3/node.c | 7 ++++ dlls/msxml3/tests/domdoc.c | 66 +++++++++++++++++++++++++++++++++++++++++-- 2 files changed, 69 insertions(+), 4 deletions(-) diff --git a/dlls/msxml3/node.c b/dlls/msxml3/node.c index fc15a5d..18b3db2 100644 --- a/dlls/msxml3/node.c +++ b/dlls/msxml3/node.c @@ -295,6 +295,7 @@ HRESULT node_insert_before(xmlnode *This, IXMLDOMNode *new_child, const VARIANT xmlNodePtr new_child_node;
