* Unified support using:
- internal bindiffer
- using system's diff program
* Compare list of imports or strings of given files
* Add proper apis to handle all this
* Automatic hexdump when comparing binary buffers (-U)
* Update documentation
- Optimised the distance calculation for radiff -s
- Fixed a bug in radiff.c that where verbose was always true.
- Added check that calloc() was successful.
- Shuffled code around to minimise use of free()
- Added some comments.
Speeds up the radiff2 statistical diff. Drastically reduced the ‘edit
distance search space’ by ignoring ranges that can’t affect the edit
distance. Improves search for similar files (common use case?), can
reduce the search space significantly:
One file tested went from two unknown versions of httpd, on MacBook has
a 28 hours processing time, down to ~13 minutes. Results will vary based
on file differences the more similar the files, the faster it'll run.
Implemented the iterative two matrix row version from here: https://en.wikipedia.org/wiki/Levenshtein_distance
and here: http://www.codeproject.com/Articles/13525/Fast-memory-efficient-Levenshtein-algorithm
Memory usage was originally 200Gig for a couple of 100K files ~(sizeA*sizeB), now about ~(sizeB*2)...
