The description of xmlAddChild says:
"Add a new node to @parent, at the end of the child (or property) list
merging adjacent TEXT nodes (in which case @cur is freed)."
and the description of xmlAddChildList says:
"Add a list of node at the end of the child list of the parent merging
adjacent TEXT nodes (@cur may be freed)"
Assuming that @cur is freed in the case of "merging adjacent text nodes"
(as the sentence seems to read and bolstered by the "may" in the second
description above), how is one to know whether adjacent TEXT nodes were
merged in order to know whether @cur is freed?
We had a case of a memory leak because we generally assumed @cur was
freed, but when we added an empty value text node, it was not. We don't
generally have "adjacent TEXT nodes", so it seems that "merging adjacent
TEXT nodes" is not a qualification of whether @cur is freed, which would
mean no information is necessary on the status of node merges. Our
experience is that the @cur is freed if the function succeeds, except in
the case of adding an empty text node (even though the add child
function succeeds in this case). Can you clarify when @cur is freed or
not freed?
