2017-10-17Convert XFA Doc Types to be more preciseRyan Harrison
The existing types are PDF, Dynamic & Static, which are poorly named since they don't really convey the fundamental differences between the types. "PDF" is confusing because PDFium only handles PDFs, and "Dynamic" & "Static" describe what a form may do, not how it is specified or some other fundamental difference. The terms "Dynamic" and "Static" were especially confusing, since XFAF documents must be static by definition, whereas full XFA documents can be either dynamic or static, depending on whether or not they change their layout. The types have been renamed to be clear that they are talking about the type of PDF document being described. "PDF" becomes "None", since this is used to indicate that there are no XFA forms in the document. "Dynamic" becomes "Full", since this indicates that the entire XFA spec is being used for the forms, specifically display layout is in the XML. "Static" has become "ForegroundOnly", since the form is specified using the XFAF (XFA Foreground) subset of the spec. The terms Full & Foreground come from the XFA spec. I would have preferred XFAF to have a different name, since it is the display/foreground layer that isn't XFA when using it.

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.

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.

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.

2017-07-19Rename StringCs c_str() to unterminated_c_str().Tom Sepez
Since there is no guarantee of termination if the StringC was extracted from a snippet of another string. Make it more obvious that things like strlen(str.unterminated_c_str()) might be a bad idea.

2017-07-19Use CFX_WideString in CPDF_NameTree functions to strip BOMchromium/3162Jane Liu
PDFium doesn't strip BOMs during parsing, but we should strip BOMs when retrieving parsed strings in CPDF_NameTree to ensure consistency and appropriate function behavior. See the bug for more info. As outlined in Bug=pdfium:593, the solution is to call GetUnicodeText() instead of GetString(). I added a GetUnicodeTextAt() function in CPDF_Array, which is symmetrical to GetUnicodeTextFor() in CPDF_Dictionary. I then changed the input variable types to CPDF_NameTree functions to be CFX_WideString instead of CFX_ByteString, and modified all the calls to them. I also added a unit test for nametree, which would fail prior to this change. Nametrees with non-unicode names are already tested by embedder tests.
