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.

2017-08-23Convert string Find methods to return an OptionalRyan Harrison
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.

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.

2017-08-16Fixed the return values of FPDFAnnot_Get{Rect|AttachmentPoints}Jane Liu
Currently, FPDFAnnot_Get{Rect|AttachmentPoints} would return BBox if the annotation's appearance stream is defined, which does not make much sense to the user since BBox is defined in the form space; upon rendering, the annotation's position in the device space is solely defined by its rectangle. This CL removes references to BBox in FPDFAnnot_Get{Rect| AttachmentPoints}; instead, they will only return rectangle or quadpoints as requested. The embedder test is also modified to reflect this change, and also to demonstrate that an annotation's position is changed only if its rectangle is changed.

This CL adds support for Chromium's component build feature to pdfium. The export header stub in fpdfview.h is expanded to match Chromium's export mechanisms and patterns (fixes pdfium:825). A component/shared library build can be triggered by adding is_component_build = true as a gn argument.

This CL removes the default param value for this method, which was negative. It also adds in a method to get buffer lengths, so that the callsites can explictly passing in the length of the buffer if they were using the default value previously.

2017-08-01Replace raw value for constant error value in string operationsRyan Harrison
Currently Find() and other methods that return a FX_STRSIZE return -1 to indicate error/failure. This means that there is a lot of magic numbers and magic checks floating around. The standard library for similar operations uses a npos constant. This CL implements FX_STRNPOS, and replaces usages of magic number checking. It also does some type cleanup along the way where it was obvious that FX_STRSIZE should be being used. Removing the magic numbers should make eventually changing FX_STRSIZE to be unsigned easier in the future.

This method replaces the selected text in a user-editable form text area with another text string (which can be empty or non-empty). If there is no selected text, FORM_ReplaceSelection() will append the replacement text after the current caret position.

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.
