2018-09-18Transfer ownership of nodes to top-level XML docRyan Harrison
For XFA, XML nodes are owned by the XML doc that they were created by, but references to them are stored elsewhere. For a PDF document there is one top-level XML document created and retained when the initial XFA XML is parsed. Another can be created if loadXML is called by JS. In the existing code the XML doc that owns the newly created nodes is local to loadXML. So the nodes are destroyed right after putting refernces to them into the main XFA data structures. This CL adds in a method to transfer ownership of the XML nodes from one doc to another, and uses it to correctly retain the newly created nodes, by having them owned by the top-level XML doc.

2018-09-13Introduce FX_Number class as a replacement for FX_atonum().Tom Sepez
The issue with FX_atonum() is that it doesn't return any information about whether it range-checked its integer values as a signed or unsigned type, even though it knows this as part of its processing. Rather than adding another out parameter to that function, create a class to hold all this information together. This is the first place things went astray while diagnosing bug 882959, in that a large positive value was cast to float as a negative value. Unfortunately, this doesn't affect the related bug, but is a step in the right direction.

2018-09-12Optimize CPDF_CMapParserRyan Harrison
In this parser, a vector of CodeRange values are built up during operations that need to be sync'd with the CPDF_CMap that is being initialized. In the existing implementation, the vector being built as a member var for the parser, and copying the values over to the cmap whenever there is a change. When profiling, this copy is where the code spends most of its time. The code has been rewritten to have the parser reference/modify the instance of the vector in the cmap instead of having its own copy. This removes all of the copies and significantly speeds things up.

When parsing happens in several steps (in pages with > 100 page objects), the position is reset to 0 and the start pointer is advanced. This breaks the calculation of which stream an object belongs to. Passing in the base pointer separately from the start offset allows the correct position to be calculated and the correct stream to be identified.

2018-09-06Rename CFX_GifContext::ReadData() to ReadAllOrNone()Tom Sepez
The whole point of this wrapper method is to disallow partial reads, so name it accordingly. No functional change.

2018-09-04Consolidate some common code in ccoded_progressivedecoder.Tom Sepez
Small consolidation before trying to fix a memory issue. Unfortunately, this involves converting a switch -> ifs, since we no longer dispatch exactly the same.

2018-09-04Fix some more span/memcpy interactions.Tom Sepez
Use the preferred idiom of creating a subspan, which makes the proper checks prior to the copy. Change-Id: Ia7f25b5760dea5707df66cf421195b23a1ce0ad0 Reviewed-on: https://pdfium-review.googlesource.com/41911 Commit-Queue: Tom Sepez <tsepez@chromium.org> Reviewed-by: Lei Zhang <thestig@chromium.org>
2018-09-04Avoid CHECK in fpdf_parser_decode.cpp (memcpy empty span)Tom Sepez
Given a span of size N, memcpy(dest, &span[N], 0) ought to be a no-op, but since we compute span[N] before checking for zero length, we hit an assert. The correct idiom should be to create a sub-span, which allows specifying N, but only when the size is 0.

It's always passed as nullptr. It's a good thing, too, since it looks like some of the implementations are returning a wrong pointer. Add some missing |const|s.
