2017-06-20Cleanup tiling and shading patterns in correct orderDan Sinclair
When a Shading is created we have both a ShadingPattern and a ShadingObject. The ShadingPattern is a ref-counted object that is stored in the CPDF_DocPageData. The ShadingObject, when we have a tiling pattern parent, is stored in the CPDF_Form of the tiling pattern. Currently during destruction it is possible for the ShadingPattern to get cleaned up before the ShadingObject which causes the UnownedPtr probe to fire. This CL loops over all patterns and for each Tiling pattern forces the CPDF_Form to get cleared. This then removes the ShadingObject before we remove the ShadingPattern.

2017-06-19Add heuristic for improving text rendering in CPDF_CharPosList::LoadNicolas Pena
This CL uses the following algorithm for improving substitute font spacing (we are assuming the text layout is horizontal): * Calculate PDFWidth, the width that the PDF says the glyph should have. * Calculate FTWidth, the width calculated by freetype for the glyph, using the substitute font that we'll use to render it. Note that some embedded fonts have PDFWidth == FTWidth + 1, so we consider that to be matching widths. * If PDFWidth > FTWidth + 1 , move the x coordinate by the difference / 2 so that the glyph is rendered in a more centered spot and the text looks better. * If PDFWidth < FTWidth, transform the glyph horizontally by PDFWidth / FTWidth so that the glyph gets compressed and does not overlap with surrounding glyphs.

2017-06-13Allow zero length streams when parsing.chromium/3130Dan Sinclair
It's possible to create a stream of length 0 in a PDF document. Currently the code will early exit and return a nullptr. This causes issues when you want to print the given PDF as the FPDF_ImportPages code ends up only generating up to the zero length object. This CL allows creating streams with length 0 and updates the PDF saving code to output a blank stream.

CPDF_PageRenderCache::m_ImageCache is a map from streams to an image cache entry containing a clump of data associated with the stream. Oddly, the clump includes the stream key (which we already have in order to get to the clump), but worse doesn't ensure the existence of the CPDF_Image object which (maybe) owns the stream key in question. So replace the stream with a retained ptr to the image. Also renamed an unrelated member to avoid confusion with the CPDF_Object in play.

2017-05-16Introduce CFX_UnownedPtr to detect lifetime inversion issues.Tom Sepez
There are places where an object "child" has a raw pointer back to object "owner" with the understanding that owner will always outlive child. Violating this constraint can lead to use after free, but this requires finding two paths: one that frees the objects in the wrong order, and one that uses the object after the free. The purpose of this patch is to detect the constraint violation even when the second path is not hit. We create a template that is used in place of TYPE*. It's dtor, when a memory tool is present, goes out and probes the first byte of the object to which it points. Used in "child", this allows the memory tool to prove that the "owner" is still alive at the time the child is destroyed, and hence the constraint is never violated.
