2017-09-18Convert string class namesRyan Harrison
Automated using git grep & sed. Replace StringC classes with StringView classes. Remove the CFX_ prefix and put string classes in fxcrt namespace. Change AsStringC() to AsStringView(). Rename tests from TEST(fxcrt, *String*Foo) to TEST(*String*, Foo). Couple of tests needed to have their names regularlized.

2017-08-09Unify of saving documents.chromium/3181Artem Strygin
In the original code the method of writing of objects depends on a much unpredictable factors: as: 1) Is there an updated version of the at least one object in the document. 2) The password is changed. 3) Was this object loaded earlier. 4) The Object is compressed and document have a password. With these factors it is difficult to predict what will be the final file. To reduce volatility use only one method that works in all cases mentioned. This method is parse then serialize.

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.
