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.

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.

2017-07-20Change length calculation in CFX_StringCTemplate constructorRyan Harrison
Originally this would only calculate the length of the passed in string if the passed in length was -1. This causes issues, since other negative values will be passed straight through and break the post-condition on the constructor of the length being non-negative. This leads to undefined and hard to debug behaviour later, in cases where the root cause is a mistake in calculating the proper length. The other related classes, CFX_WideString & CFX_ByteString, test for all negative length values and calculating the length when they occur. This CL changes the FooC versions to use this logic. This implicitly assumes the string is null terminated, so in the incase of an incorrect negative length and a non-null terminated string there will still be a crash, but it will now occur at construction time, instead of at some random later time.

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.
