So with a bit of digging in CVS (yeah!) ... on only one file (gmatch.c), it looks like the original commit had this caldera license header alright and that must have been added when porting from the 7th edition, per the "Derived from /usr/src/cmd/sh/expand.c, Unix 7th Edition:" comment in that file. https://minnie.tuhs.org/cgi-bin/utree.pl?file=V7/usr/src/cmd/sh/expand.c did not have such notice. So I would surmise that Gunnar Ritter (Heirloom's original creator) took the original 7th edition code from TUHS and used the TUHS-provided Caldera notice (such as at https://www.in-ulm.de/~mascheck/bourne/Caldera-license.txt ) to add as a comment in the code. The timeline of various events supports this analysis. Sven Mascheck <masch...@in-ulm.de> has an extensive Shell history at https://www.in-ulm.de/~mascheck/bourne/#heirloom including a Heirloom shell commit log that matches the CVS's log at https://sourceforge.net/projects/heirloom/ With all that said, the license text that we discuss here and as seen in gmatch.c is IMHO closest to a plain BSD-4-Clause with minor variations (e.g. scope of source and documentation vs. only source in BSD-4-Clause) so if the intro blurb seen in the SPDX Caldera text is not material, then may be the body text itself could be just a minor variant of the BSD-4-Clause. Someone could bug Gunnar Ritter at <gunn...@acm.org> of course to get confirmation. -- Cordially Philippe Ombredanne +1 650 799 0949 | pombreda...@nexb.com DejaCode - What's in your code?! - http://www.dejacode.com AboutCode - Open source for open source - https://www.aboutcode.org nexB Inc. - http://www.nexb.com -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.
