List of GRASS Versions (1984-today)

Issues and vetting process

  • Ongoing: Missing copyright statement addition are continuously added
    • To simplify to trace down code contributors, there is a PERL script (tools/copywrite.pl) in the source code which automatically searches all main.c files which are lacking a Copyright statement. It also automatically extracts the known contributors from the local ChangeLog file (which is created on the fly from CVS) and generates a standard header within such main.c file. Manual review is obviously still needed before submitting the updated file to CVS.

Included Libraries

see lib/external/

Non-free Libraries

There are no non-free libraries included. Vetted during GPL'ization, DebianGIS'ization and ongoing.

Code Reviewed

Code provenance review procedure

It was a manual, interactive procedure with some scripted help. The automated part included:

  • search of main.c files without copyright statement (those with GPL statement have been vetted already 1-2 times earlier, see grass-dev archive)
  • extraction of ChangeLog for the actual main.c file from CVS
  • extraction of authors from Changelog file and draft insertion into actual main.c
  • open of text editor with following files:
    • main.c in process
    • related description.html (which contains authors at page bottom; in order to check for unmentioned authors from the pre-CVS times)
    • local Changelog file

Then the reviewer browsed main.c for offensive code (essentially incompliant copyright notices and such), added missing authors to the copyright header from description.html and polished the layout of the copyright header. Then submission to CVS (now OSGeo GRASS SVN).

Kudos to Schuyler Erle for writing the PERL script which quite helped (tools/copywrite.pl). The expansion of CVS names was done by reading in contributors.csv. M Neteler feel that this is a valid level of automatisation.

Reminder: the GRASS Development Team has already done rigorous code vetting when GRASS was made GPL'ed software (1999).

Note 1: All contributors with SVN access have agreed to RFC2: http://download.osgeo.org/grass/grass6_progman/rfc/rfc2_psc.html (RFC 2: Legal aspects of code contributions)

Note 2: All added copyright statements are documented in ChangeLog (now also in trac): http://grass.osgeo.org/grass63/source/snapshot/ChangeLog.gz
