We cache pages not by page number, which can bounce around as pages are inserted or removed, but by page dictionary's object number. Since the page may be created under one function and used under another, we can't take the shortcut of not instantiating a render cache nor not parsing the page.

2018-05-25Make CPDF_Page retainable.Tom Sepez
Small step to reducing the differences between XFA and non-XFA. We still use the RetainPtr pretty much as if it were an unique_ptr, in that we're not yet caching pages and handing out multiple pointers to the same page in the non-XFA case. The one change is in page view cleanup, where we no longer need a boolean and can take (sufficient) page ownership with a RetainPtr. Tidy up some document.h -> page.h -> document.h circular inclusion while we're at it. NOTE: Wait for imminent branch to pass before landing. We'll want this to bake a while.

2018-04-12Return pdfium::span<wchar_t> from WideString::GetBuffer().Tom Sepez
Adds bounds checking "for free", but beware of span outliving a ReleaseBuffer() call. Scoping as such avoids the possibility of using an invalid span (and it is flagged as a lifetime issue).

2018-04-12[xfa] Remove form checksum abilitiesDan Sinclair
This CL removes the code for verifying and creating checksums associated with form elements in XFA documents. This was the only code requiring the SAXReader which has also been removed. According to the XFA spec and application can decide which parts of the signatures are supported. This feature is being removed until we determine if/when it is needed.
