Bill Mitchell updated AXIS2C-675:
---------------------------------
Attachment: diff.txt
I've updated the attached diff to include two additional changes.
(1) Detach is now included as one of the actions of axiom_node_free, when the
node still has a parent. All the appropriate points in Axis have been changed
to take advantage of this. This allows the free process to perform an internal
detach that avoids preserving the integrity of namespace references.
(2) When a node is detached, it determines all the namespaces in its parents
that may be inscope for it or its children. The new action is then to scan the
subtree to determine which of these namespaces are actually referenced in the
subtree, and to redeclare only the namespaces that are actually referenced.
Senaka, I think that (2) resolves most of your concern about increasing the
size of the payloads with unused namespace declarations, at the cost of
scanning the subtree during detach. I do have a clever idea of something that
could be done during attach, to further address your payload size concern
without modifying all the namespace reference values. We could promote the
declared namespaces up the tree to a higher parent, detecting if the namespace
has already been declared at the higher node. This would eliminate multiple
declarations when multiple detached subtrees are attached to a new tree. I'm
reluctant to implement this, though, as it would make no difference in the case
with which I'm familiar of the generated adb stubs. The adb classes serialize
the pieces of the request message directly, without first collecting them into
one tree via attach, so repetitive namespace declarations in multiple passed
request objects would not be removed.
