Bug 63540 – XMLDocumentParserQt.cpp incorrectly converts 0-based number into 1-based number

• Status: RESOLVED
• Resolution: FIXED
• Component: WebKit Qt

[Peter Rybin]

Its method textPositionOneBased has incorrect converting. Now that number are typed it is evident. Probably underlying m_stream.lineNumber is incorrectly reinterpreted as 0-based value.

Usually we add "using WTF::ZeroBasedNumber" to the header so we don't need to use the WTF macro everywhere.  Have you validated that the new line numbers in the tests are all right?

I considered this type somewhat temporary (2 type are to be merged into "BasedNumber" maybe). However let me try to add 'using' anyway.

Yes, I went over all expectations and checked that the new numbers are correct.

Should m_tokenizer->lineNumber() return a ZeroBasedNumber ?

I think so. I'm going to change it in the next bug/patch. However I realize that I won't be able to replace all integers with *BasedNumbers myself everywhere.
