Oh, er, well, this is a bit embarrassing. It turns out my tests were insufficently devious, and did not guard against invalid UTF-8 encodings. I thought I could punt on UTF-8 validation and rely on [NSString initWithBytes:length:encoding] to do it, but then Nicolas Seriot reported otherwise (issue #219). The result is that this version won't crash on a whole range invalid UTF-8 byte sequences where previous versions crashed did:
- Flat-out illegal UTF-8 byte values
- Missing continuation bytes
- Unexpected continuation bytes
- Overlong encodings
- Invalid Unicode code points
After 9 years of calling SBJson a strict JSON parser I've finally implemented UTF-8 validation. Thank you for the learning opportunity Nicolas!
Also in this release:
- Recreate the project file and targets using Xcode 8.
- Re-organising the frankly bonkers repo layout to hopefully make it easier for casual contributors to find their way around.
- Fix the Travis build; this had broken due to bit rot.
