Subject: [PATCH 7/7] Fix memory management of xmlNs xpath results
this commit introduces a bifurcation in how Namespace objects are
managed; Namespace objects wrapped around xmlNs structs from an xpath
query now have their own Ruby object lifecycle and are GCed
independently from their original document.
See comments in xml_node_set.c and xml_namespace.c for more details.
Related to #1155

- * xmlXPathFreeNodeSet() contains an implicit assumption that it is being

- * assumption lies in the operation where it dereferences nodeTab pointers
- * while searching for namespace nodes to free.
*
- * however, since Ruby's GC mechanism cannot guarantee the strict order in
- * which ruby objects will be GC'd, nodes may be garbage collected before a
- * nodeset containing pointers to those nodes. (this is true regardless of
- * how we declare dependencies between objects with rb_gc_mark().)
+ * since xpath queries return copies of the xmlNs structs,
+ * xmlXPathFreeNodeSet() frees those xmlNs structs that are in the
+ * NodeSet.
*
- * as a result, xmlXPathFreeNodeSet() will perform unsafe memory operations,
- * and calling it would be evil.
+ * this is bad if someone is still trying to use the Namespace object wrapped
+ * around the xmlNs, so we need to avoid that.
*
- * "In Valgrind We Trust." seriously.
+ * here we reproduce xmlXPathFreeNodeSet() without the xmlNs logic.
+ *
+ * this doesn't cause a leak because Namespace objects that are in an XPath
+ * query NodeSet are given their own lifecycle in
+ * Nokogiri_wrap_xml_namespace().
