From 883031fb45cf0f86cd36b20ad4762da58dd6126c Mon Sep 17 00:00:00 2001 From: Arseny Kapoulkine Date: Wed, 15 Oct 2014 06:05:49 +0000 Subject: XPath: Fix optimization bug with //name[last()] The actual condition for the optimization is invariance from context list -- this includes both position() and last(). Instead of splitting the posinv concept just include last() into non-posinv expressions - this requires sorting for boolean predicates that depend on last() and do not depend on position(). These cases should be very rare. git-svn-id: https://pugixml.googlecode.com/svn/trunk@1060 99668b35-9821-0410-8761-19e4c4f06640 --- src/pugixml.cpp | 1 + 1 file changed, 1 insertion(+) (limited to 'src') diff --git a/src/pugixml.cpp b/src/pugixml.cpp index 7db62d0..484f34b 100644 --- a/src/pugixml.cpp +++ b/src/pugixml.cpp @@ -9621,6 +9621,7 @@ PUGI__NS_BEGIN switch (_type) { case ast_func_position: + case ast_func_last: return false; case ast_string_constant: -- cgit v1.2.3
