scancode-toolkit 2.0.0

2.0.0 (2017-06-23)

This is a major release with several new and improved features and bug fixes.

Some of the key highlights include:

• License:

  • Brand new, faster and accurate detection engine using multiple techniques eventually doing multiple exhaustive comparisons of a scanned file content against all the license and rule texts.

  • Several new licenses and over 2500+ new and improved licenses detection rules have been added making the detection significantly better (and weirdly enough faster too as a side-effect of the new detection engine)

  • the matched license text can be optionally returned with the –license-text option

  • The detection accuracy has been benchmarked against other detection engine and ScanCode has shown to be more accurate and comprehensive than all the other engines reviewed.

  • improved scoring of license matches

• Package and dependencies:

• new and improved detection of multiple package formats: NPM, Maven, NuGet, PHP Composer, Python Pypi and RPM. In most cases direct, declared dependencies are also reported.

• several additional package formats will be reported in the future version.

• note: the structure of Packages data is evolving and should not be considered API at this stage

• Scan outputs:

• New SPDX tag/values and RDF outputs.

• new compact JSON format (the pretty printed format is still available with the the json-pp format). The JSON format has been changed significantly and is closer to a documented, standard format that we call the ABC data format.

• Minor refinements on the html and html-app format. Note that the html-app format will be deprecated and replaced by the new AboutCode Manager desktop app (electron-based) in future versions.

• Copyright: Improved copyright detection: several false positive are no longer returned and copyright s are more accurate

• Archive: support for shallow extraction and support for new archive types (such as Spring boot shell archives)

• Performance:

• Everything is generally faster, and license detection performance has been significantly improved.

• Scans can run on multiple processes in parallel with the new –processes option speeding up things even further. A scan of a full Debian pool of source packages was reported to scan in about 11 hours (on a rather beefy 144 cores, 256GB machine)

• Reduced memory usage with the use of caching

• Other notes:

  • This is the last release with Linux 32 bits architecture support

  • The scan of a file can be interrupted after a timeout with a 120 seconds default

  • ScanCode is now available as a library on the Pypi Python package index for use as a library. The documentation for the library usage will follow in future versions

  • New –ignore option: You can optionally ignore certain file and paths during a scan

  • New –diag option: display additional debug and diagnostic data

  • The scanned file paths can now reported as relative, rooted or absolute with new command line options with a default to a rooted path.

Thank you to all contributors to this release and the 200+ stars and 60+ forks on GitHub!
