2017-06-28Set default graphics before generating page contentsNicolas Pena
In this CL, the content generator sets some default graphics states before processing the page objects. In particular, a default ExtGState is now set before processing, and the last CTM is now stored right after parsing finishes: the only command to change matrix is ctm, and it concatenates, so inverting requires knowing the current value.

CPDF_PageContentGenerator currently only works for CPDF_Page objects. However, CPDF_Form is also a CPDF_PageObjectHolder like CPDF_Page, and content streams can be generated for form objects too. This CL modifies the content generator to work with both forms and pages. The content generator will later be used on annotation objects' CPDF_Form to simplify the code for annotation AP stream generation.

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.

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.
