2018-09-25Introduce CodecModuleIface for progressive decoder modules.Tom Sepez
Another step before trying to fix the memory issue. Forces common APIs on the bunch of decoders, though some methods are unused. Requires adding some arguments/return values to get to a common API which are not used in all cases (yet?). Required converting some args to spans. Required proxying a GetJumpMark() call through the public module API to the private context.

2018-09-21Cleanup in CCodec_FaxModuleNicolas Pena
This CL moves FaxG4Decode to the class where it's implemented. It should remain there because it calls FaxG4GetRow, declared and used in the cpp file. Do some ++ cleanup while at it. This CL also makes CCodec_FaxModule own some methods that were namespaced since doing so allows removing a bunch of parameters.

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.

This reverts commit 882ed81dec7afc5bc106f965af34f1e59407fd95. Reason for revert: Rule out that this be making embeddertest flakey. Seems improbable, but maybe the const is allowing the compiler to use stale data in a non-logically const operation ???

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.

2018-09-12Set correct stream index when parsing is done in several steps.Henrique Nakashima
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.
