2017-05-17CFX_UnownedPtr: check during assignment time as well.Tom Sepez
In particular, doing m_pPtr = nullptr; in your dtor to evade this check will not longer work. Fix slight mis-ordering observeds in CFX_Font and CPDFXFA_Context.

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.

2017-04-19Cleanup codepage and charset definitions.Dan Sinclair
This Cl cleans up the unused defines in fx_codepage.h. The FXFONT_CHARSET_ defines are replaced with fx_codepage defines, this moves fx_codepage into core instead of xfa only. Static asserts are added to verify the public/ charsets match the fx_codepage charsets.

2017-02-07Use enum class for PathPoint types.Nicolas Pena
This hopefully makes it less confusing what the description of a point is. Currently we have defines for the types, which is confusing because a point can only be one of the three. And it is mixed up with whether the point is closing a figure or not.

We can remove a lot of "bOwnsStream" logic in the process. Always pass these by const reference, in case the called method wants to hang on to the stream (one exception is where we stick a raw pointer into a void* slot in a context from another layer).

2016-11-21use skia textcaryclark
This adds text to the _SUPPORT_SKIA_PATHS_ variant. The output of the test corpus has more differences, but no feature changes or dropouts that I can see. The text is a bit lighter. Bungeman thinks this is because of our support of SRGB color, although the fonts also look different so maybe there's more to the story. The output looks compatible with the variations I see in Adobe Reader and Firefox on the same platform. There's probably more text tuning to do. Additionally, this turns off the caching feature for this variation. Caching can't work because the drawing alternates between Skia and PDFium's native blits, so any state caching won't know about changes and drawing performed by the other.
