Update year in copyright

Symfony2 - Copyright (c) 2004 - 2012 Fabien Potencier needs to change to Symfony2 - Copyright (c) 2004 - 2015 Fabien Potencier Source: http://symfony.com/doc/current/contributing/code/license.html

Twig - Copyright (c) 2009 Twig Team also needs to change to Twig - Copyright (c) 2009 - 2014 by the Twig Team Source: http://twig.sensiolabs.org/license

@thpoul This makes me wonder how many other libraries ship with Drupal that are not mentioned in this file. And, why we would need to mention them at all because most, if not, all should ship with their own copyright notices.

Based on (emphasis mine)...

Drupal includes works under other copyright notices and distributed
according to the terms of the GNU General Public License or a compatible
license, including:

...it is a partial list. But what is the standard for including a given library's copyright in this file?

I wonder if the Licensing Working Group could help.

Ok, one more tag, sorry about the noise.

Sorry!

@bserem From what I read via Google and my very limited understanding of copyright, it may be that only the first year need be listed. But, take that with a grain of salt.

From #4:

I wonder if the Licensing Working Group could help.

I agree that one or more lawyers familiar with copyright law (international or U.S.) ought to weigh in. Is there a recommended way to bring this issue to that group's attention?

Regarding #9, it might also be the case that no start and no end year is required; I'm just not sure.

I opened #2725083: Are the years necessary in a copyright declaration?, but how about as per #8 we just mark this RTBC and get it fixed?

I'm putting this back to RTBC.

I do not believe that we should be changing the copyright messages in third party software (Symphony, Twig, etc). There may be a reason for that specific year / range that we are unaware of.

Therefore, we should only change the copyright messages for Drupal itself and leave all other copyright notices as is.

@John Cook: It turns out that is the future, but it isn't the current policy. See the discussion on #2725083: Are the years necessary in a copyright declaration?

In light of the actual policy, I think we have got missing a few 3rd-party licenses in COPYRIGHT.txt.

Set to Needs work because of the comment from cilefen and the contents of COPYRIGHT.txt.

On 8.2.x before running composer install, so it's just the drupal repo, I have run the following command:
grep -irn "Copyright .*\-.*20[01][0-9]" * | grep -v "\-.*2016"
This should get any copyright notices not ending with 2016.

The results are as follows:

core/COPYRIGHT.txt:1:All Drupal code is Copyright 2001 - 2013 by the original authors.
core/COPYRIGHT.txt:57:  ArchiveTar - Copyright (c) 1997 - 2008 Vincent Blavet

Just to note this is without the patch applied.

Test bot being silly.

Hi John Cook,

I don't know why the bot is saying failed testing.

Please review it.

Thanks!!

Happy New Year.
