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.

2017-10-10Fix dangling pointer to ID array in CPDF_SecurityHandler.chromium/3238chromium/3237Henrique Nakashima
This was caused by breaking the reference from CPDF_SecurityHandler to CPDF_Parser in https://pdfium-review.googlesource.com/c/pdfium/+/15290 The reference was replaced with a reference to the ID Array and a copy of the password. The issue is that when parsing PDFs with multiple trailers, the trailer containing the ID array may be replaced and destroyed in CPDF_Parser::TrailerData::SetMainTrailer() after being passed to CPDF_SecurityHandler, which would then have a dangling pointer to it. This CL changes the CPDF_SecurityHandler to hold a copy of the original file ID instead of all the ID Array.
