2018-04-27Avoid potential duplicate unique_ptr to CPDF_Document from CPDFXA_Context.Tom Sepez
Should FPDFDocumentFromCPDFDocument() be called several times under XFA, we may WrapUnique() the document several times. So cache a pointer back from CPDF_Document to CPDFXFA_Context to avoid this. Because of layering, introduce a placeholder type CPDF_Document::Extension. This is actually the first step in some larger XFA ownership cleanup, but makes a nice standalone CL around the one particular issue.

2018-04-25Don't store CE (comment extension) block data when decoding GIFRyan Harrison
GIF extensions are laid out as follows: <size byte> <chunk of data> <size byte> <chunk of data> ... <terminator byte>. The decoder needs to scan along the data, finding the size bytes to determine where the block ends in the stream, even if we don't care about the content. Currently the decoder is storing all of the data chunks, which are never used and take a lot of time to concat together if they are very small. Our implementation of the GIF spec does not handle this extension, so when scanning for the end of the block, just don't bother storing data from it.

The current implementation of this class potentially does a lot of work in the constructor. Specifically when getting a calendar font it might cause the whole font loading pipeline to run. This can fail if it is unable to load fonts. Breaking out the font loading part, so that the factory method can return nullptr if it fails. Additionally adding a guard for the case the font manager fails to load, which is the root cause of the crash in the bug.

2018-04-23Pre-allocate more string buffers in barcode codeRyan Harrison
Another couple of examples where the slow down in the barcode code can be fixed by reserving and thus pre-allocating the buffer that backs the Widestring. Doing += in a tight loop caused reallocation thrashing.

This CL changes CFX_XML to use an IFX_SeekableWriteStream instead of the more generic IFX_SeekableStream. This is a reland of https://pdfium-review.googlesource.com/c/pdfium/+/30877 without pulling in the XML lifetime changes.

2018-04-23Validate the Size dictionary entry in CPDF_SampledFunc.Lei Zhang
It is required to be an array of positive integers. The existing implementation seems to accommodate non-compliant PDFs where the Size entry is an integer.
