2017-08-30Convert int* references to FX_STRSIZERyan Harrison
Through out the code base there are numerous places where variables are declared using a signed integer type when interacting with the string classes, since they assume that FX_STRSIZE is 'int'. As part of changing the underling type of FX_STRSIZE to be unsigned, these locations are being changed to use FX_STRSIZE. This is necessary as part of converting the type, but has been broken off into a separate CL, since it should be low risk. Some related cleanups that are low risk are included as part of this CL.

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.

The Find and ReverseFind methods for WideString, WideStringC, ByteString, and ByteStringC have been converted from returning a raw FX_STRSIZE, to returning Optional<FX_STRSIZE>, so that success/failure can be indicated without using FX_STRNPOS. This allows for removing FX_STRNPOS and by association makes the conversion of FX_STRSIZE to size_t easier, since it forces checking the return value of Find to be explictly done as well as taking the error value out of the range of FX_STRSIZE. New Contains methods have been added for cases where the success or failure is all the call site to Find cared about, and the actual position was ignored.

The previous behaviour of [] on an empty string was to return 0 regardless of the index. We wanted to make this more strict, hence the current behaviour. This has led to a number of crashes due to code depending on the old behaviour. Reverting to the old behaviour until we have time to correct the call sites using empty strings.

2017-08-22Corrected the error setting after calling FPDF_LoadDocument()Jane Liu
Currently, if FPDF_LoadDocument() is called on a nonexistent file, the returned FPDF_DOCUMENT will be null, but FPDF_GetLastError() will return an error of FPDF_ERR_SUCCESS, i.e. no error. This CL corrects this behavior by updating the error to be FPDF_ERR_FILE when the file doesn't exist.
