2017-08-23Fixed ASan crash when unloading page with CFFL_ListBox.Henrique Nakashima
The crash was caused by a dangling pointer in CPWL_ListCtrl to the font map owned by CFF_TextObject. The order of events was: 1. ~CFFL_ListBox runs and calls parent destructor ~CFFL_TextObject. 2. ~CFFL_TextObject runs and deletes its member m_pFontMap. m_FontMap was referenced by CPWL_ListCtrl which is now dangling. 3. ~CFFL_TextObject calls parent destructor ~CFFL_FormFiller. 4. ~CFFL_FormFiller calls DestroyWindows(). 5. CFFL_FormFiller::DestroyWindows() deletes widgets, among them CPWL_ListBox. 6. ~CPWL_ListBox deletes its member CPWL_ListCtrl. 7. ~CPWL_ListCtrl sees a dangling pointer to the map and crashes. Making the DestroyWindows() call earlier in the destructor of CFFL_TextObject, we execute steps 5-7 before freeing m_pFontMap. An extra DestroyWindows() is still made in ~CFFL_FormFiller, but it is then non-op if the derived CFFL_TextObject already called it.

2017-07-28Convert calls to Mid() to Left() or Right() if possibleRyan Harrison
The various string/byte classes support Mid(), Left(), and Right() for extracting substrings. Mid() can handle all possible cases, but Left() and Right() are useful for common cases and more explicit about what is going on. Calls like Mid(offset, length - offset) can be converted to Right(length - offset). Calls like Mid(0, length) can be converted to Left(length). If the substring being extracted does not extend all the way to one of the edges of the string, then Mid() still needs to be used.

2017-07-27Remove single param Mid() method from string classesRyan Harrison
This support is being removed from CFX_ByteString, CFX_ByteStringC, CFX_WideString, and CFX_WideStringC. This standardizes all of these classes to only have one Mid method that takes in 2 params, offset and count. Count now must be positive. The old behaviour of calculating the length for the user if -1 is passed in for the count has been removed. This work is in preperation for converting these classes to not accept negative lengths anywhere and thus make the underlying size type unsigned.
