2017-05-03SetPos to at most the file length to avoid overflowsNicolas Pena
This CL prevents arbitrary position setting which may cause integer overflows. In the bug in question, the PDF says the xrefs are located in a huge position. This then causes problems when calling CPDF_SyntaxParser methods.

2017-04-20Convert IFX_MemoryStream to CFX_MemoryStreamDan Sinclair
The CFX_MemoryStream is the only implementation of IFX_MemoryStream. This CL removes the interfaces and uses CFX_MemoryStream directly.

2017-04-20Cleanup the fx_extension code.Dan Sinclair
This CL cleans up the fx_extension file. The stream code was moved to fx_stream. IFX_FileAccess was removed and CFX_CRTFileAccess split to its own file. Code shuffled from header to cpp file.

2016-12-07Refcount all the IFX_ stream classes all the time.tsepez
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).

2016-11-18Make CPDF_Dictionary use unique pointers.chromium/2926tsepez
Some changes were required to match underlying ctors as invoked by the templated methods. Many release() calls go away, a few WrapUniques() are introduced to avoid going deeper into other code. Review-Url: https://codereview.chromium.org/2510223002
2016-11-09Do not load main cross ref table for first page in linearized pdf.art-snake

2016-11-09Return unique_ptr from CPDF_Object::Clone().tsepez

In turn, propgate to callers. This introduces a few release() calls that will go away as more code is converted. It also removes a couple of WrapUnique calls that are no longer needed as ownership of the object flows along. Review-Url: https://codereview.chromium.org/2479303002
