Hi,

I found that license file COPYING is different as compared with http://www.gnu.org/licenses/gpl-2.0.txt If I pass over with Linus's preamble, change is only about whitespaces - tabs vs. space. Probably it's minor non-essential change, but some projects do this change, so rather I ask about that.

Regards, Petr

Interesting. I cannot quite connect "some projects do this change" and "so rather I ask". Are you asking why this project changed it?

After running "diff" between the two, I think the changes are only on the indented section title lines, and "git blame" tells us that the section title lines in the copy we have has always been that way since Linus added to it at 075b845a (Add a COPYING notice, making it explicit that the license is GPLv2., 2005-04-11).

So, perhaps the copy Linus got originally had leading runs of spaces that are multiples-of-8-long unexpanded to leading tabs back then, or perhaps he did that unexpanding himself.

Nope. I apologize for my czenglish. It means: From my colleagues I hear, that some projects had same differences (tabs vs. spaces) in their copy of the license file and they make it later equivalent with the one in gnu.org. So I ask rather here / point out this difference, if you know about that or you want to have same one.

Yes, I know, it's just about whitespaces.
Petr.

I'd guess that these projects (among which Linux kernel still has these indentation the same as the copy we have) and we independently obtained the COPYING file from GNU in some past, and back then the copy at GNU was indented that way--which later was changed.

The Wayback Machine supports this theory.
https://web.archive.org/web/20070713225446/http://www.gnu.org/licenses/gpl-2.0.txt

i.e. the FSF copy back in 2007-07 indented these section headers with tabs, so those projects that obtained this copy would have their sections indented with tabs.

At 703601d6 (Update COPYING with GPLv2 with new FSF address, 2010-01-15), we did a fresh update directly from the URL you cited above to primarily replace the addresses of the FSF office.

https://web.archive.org/web/20100105100239/http://www.gnu.org/licenses/gpl-2.0.txt
matches what we use (minus Linus's preamble, of course).

The file before that change was what Linus copied from Linux kernel project. The kernel project did their equivalent change at their b3358a11 ([PATCH] update FSF address in COPYING, 2005-09-10), and the log message says http://www.gnu.org/licenses/gpl.txt was used.

The Wayback Machine agrees.
https://web.archive.org/web/20050901115237/http://www.gnu.org/licenses/gpl.txt

i.e. the FSF copy back in 2005-09 matches what the kernel uses (again, minus Linus's preamble).

So the answers are:
 - No, I didn't personally know about the differences, and I suspect
   nobody particularly cared.
 - Not really, unless the difference has more substance.  For an
   example of an update with substance, the update we did in 2010
   had not just the FSF address change but also updated the fully
   spelled name of LGPL from Library to Lesser.

You may want to bug the kernel folks to update their copy; they still spell it as Library General Public License.

I have expected that license was copied correctly in the past from gnu.org, when same differences are in various projects. I just point out on another change.

Thank You for tip about web.archive.org - I really don't know about that web and it can be useful.

Everyone can do that. I believe that someone report it already or at least constult it. I write about this here because I should do that. When You know about this difference in license in kernel, I believe that they know it too and they decide it is ok.

Re: COPYING tabs vs whitespaces

As a reference for this discussion, see c376d96 in git.git or e00bfcbf04 in linux.git which deals with whitespaces in the developers certificate of origin.

Just send a patch, I'd say.

Thanks, Stefan

Just patch makes from whole thread more and more absurd discussion, no offense. Don't matter if it is used or not. For me it's significant previous response from Junio.

I am not familiar with git send-email, so:
