In particular, doing m_pPtr = nullptr; in your dtor to evade this check will not longer work. Fix slight mis-ordering observeds in CFX_Font and CPDFXFA_Context.

2017-05-16Introduce CFX_UnownedPtr to detect lifetime inversion issues.Tom Sepez
There are places where an object "child" has a raw pointer back to object "owner" with the understanding that owner will always outlive child. Violating this constraint can lead to use after free, but this requires finding two paths: one that frees the objects in the wrong order, and one that uses the object after the free. The purpose of this patch is to detect the constraint violation even when the second path is not hit. We create a template that is used in place of TYPE*. It's dtor, when a memory tool is present, goes out and probes the first byte of the object to which it points. Used in "child", this allows the memory tool to prove that the "owner" is still alive at the time the child is destroyed, and hence the constraint is never violated.

2017-03-22Remove unused docview flagDan Sinclair
When creating the XFA doc view we always pass the same docview flag (0). So, the map will only ever have one item in it. This Cl simplifies the code by removing the map and just dealing with a single doc view.

We can remove a lot of "bOwnsStream" logic in the process. Always pass these by const reference, in case the called method wants to hang on to the stream (one exception is where we stick a raw pointer into a void* slot in a context from another layer).
