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.

Widgets as returned from GetWidgets() can pop out of existence unexpectedly, so always return observed pointers. This extends the same pattern used elsewhere in the file to all occurrences. BUG=679642 Review-Url: https://codereview.chromium.org/2624933002
2016-11-21Fixup lint flags.Dan Sinclair
The -build/include setting was masking out build/include_what_you_use. This CL restores them, fixes any build errors, and adds NOLINT as needed. As well, the runtime/explicit and runtime/printf flags are aslo enabled and NOLINT'd. lint cleanups Change-Id: Ib013b3eb29c8d0e48cad74c5df9028684130719f Reviewed-on: https://pdfium-review.googlesource.com/2030 Reviewed-by: Tom Sepez <tsepez@chromium.org>
