Thread: more personal copyrights
Hi, A few months ago Bruce was doing a hunting of personal Copyrights notices, but i still found a lot of files copyrighted to: Regents of the University of California and other files copyrighted to individuals (ej: almost everything inside src/backend/regex is copyrighted to Henry Spencer) there's something we can/need to do about it? I can make a list if anyone is interested showing what files are still copyrighted to something different to 'PostgreSQL Global Development Group' -- Jaime Casanova www.2ndQuadrant.com Soporte y capacitación de PostgreSQL

Or at least, that's how I understand it. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise Postgres Company

We can't. What we should probably do is come up with a list of exceptions (Henry Spencer's regex library, e.g.) and a script to find all non-exception copyright notices. This will help us keep the copyrights in the code base to the standard we set. I can even see this becoming a commit- or push- hook. :) Cheers, David. -- David Fetter <david@fetter.org> http://fetter.org/ Phone: +1 415 235 3778 AIM: dfetter666 Yahoo!: dfetter Skype: davidfetter XMPP: david.fetter@gmail.com iCal: webcal://www.tripit.com/feed/ical/people/david74/tripit.ics Remember to vote!

No. The regex code was lifted whole hog from Spencer's package;
it would be most uncivilized, as well as illegal, to remove his name
from it.
The case that we are trying to eliminate is where people have put
individual copyrights on code that was written specifically for
Postgres. There's no good reason to have such files look like they
might have a license different from the rest of Postgres. However,
Spencer's code isn't in that category --- it's also in Tcl, and
I imagine it was once distributed as a standalone library.

Right, we never remove copyrights without author permission. If we can't get their approval, we will rewrite their contribution. > The case that we are trying to eliminate is where people have put > individual copyrights on code that was written specifically for > Postgres.

We do allow non-PGDG copyrights in the file, but only where we are sure that the license is BSD-compatible. For example, the copyright at the top of src/port/getopt.c probably came from a BSD-based operating system: * Copyright (c) 1987, 1993, 1994* The Regents of the University of California. All rights reserved. and below this is the BSD license. src/port/erand48.c has: * Copyright (c) 1993 Martin Birgmeier* All rights reserved. which is scary until you see the copyright under it, which seems fine: * You may redistribute unmodified or modified versions of this source* code provided that the above copyright notice andthis and the* following conditions are retained.** This software is provided ``as is'', and comes with no warranties*of any kind. I shall in no event be liable for anything that happens* to anyone/anything when using this software. The files in src/backend/regex: * Copyright (c) 1998, 1999 Henry Spencer. All rights reserved. have a personal copyright but again there is a BSD-compatible license attended to the file. No company has ever asked about these files, I think because the license below it is BSD-compatible. What I have been trying to clean up are personal copyrights aren't explicit about their license terms. -- Bruce Momjian <bruce@momjian.us> http://momjian.us EnterpriseDB http://enterprisedb.com + It's impossible for everything to be true. +
