2017-10-17Convert XFA Doc Types to be more preciseRyan Harrison
The existing types are PDF, Dynamic & Static, which are poorly named since they don't really convey the fundamental differences between the types. "PDF" is confusing because PDFium only handles PDFs, and "Dynamic" & "Static" describe what a form may do, not how it is specified or some other fundamental difference. The terms "Dynamic" and "Static" were especially confusing, since XFAF documents must be static by definition, whereas full XFA documents can be either dynamic or static, depending on whether or not they change their layout. The types have been renamed to be clear that they are talking about the type of PDF document being described. "PDF" becomes "None", since this is used to indicate that there are no XFA forms in the document. "Dynamic" becomes "Full", since this indicates that the entire XFA spec is being used for the forms, specifically display layout is in the XML. "Static" has become "ForegroundOnly", since the form is specified using the XFAF (XFA Foreground) subset of the spec. The terms Full & Foreground come from the XFA spec. I would have preferred XFAF to have a different name, since it is the display/foreground layer that isn't XFA when using it.

The Find and ReverseFind methods for WideString, WideStringC, ByteString, and ByteStringC have been converted from returning a raw FX_STRSIZE, to returning Optional<FX_STRSIZE>, so that success/failure can be indicated without using FX_STRNPOS. This allows for removing FX_STRNPOS and by association makes the conversion of FX_STRSIZE to size_t easier, since it forces checking the return value of Find to be explictly done as well as taking the error value out of the range of FX_STRSIZE. New Contains methods have been added for cases where the success or failure is all the call site to Find cared about, and the actual position was ignored.

Currently Find() and other methods that return a FX_STRSIZE return -1 to indicate error/failure. This means that there is a lot of magic numbers and magic checks floating around.

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.
