2018-09-19Validate decoder pipelines.Lei Zhang
PDF decoders, AKA filters, can be chained together. There can be an arbitrary number of decoding / decompressing filters in the pipeline, but there should be at most 1 image decoder, and the image decoder should only be at the end of the chain.

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.

2018-08-31Remove avail_buf out argument from GetAvailInput() methods.chromium/3542chromium/3541chromium/3540chromium/3539Tom Sepez
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.

2018-08-30Add unit test for AutoRestorer<> on smart pointer types.Tom Sepez
Test UnownedPtr<> and RetainPtr<>. We cannot operate against std::unique_ptr<> because we need a copyable type. Add test for self-reassignment on going out of scope. Move one test helper class to testing/ so it can be shared among unit tests. Allow it to recognize if it ever gets "destroyed", otherwise we can't be sure Retain/Release applied in the correct order.

2018-08-30Fix lifetime issue in CCodec_ProgressiveDecoder.Tom Sepez
The associated bug is caused by failure to clean up context before returing at line 740 or so. But cleanups are fragile, so instead do not move context out of a local until success. This in turn means passing the local to one helper rather that using the stored value and confirming this is the only helper method invoked during the time in which the context is not yet stored.
