License issue in mkgmap & splitter source: GPL-2 (v2 only) incompatible with GPL-3 (v3 only)
Several source files are licensed under the GPL-2 which is incompatible with GPL-3 source in splitter. To combine GPL-2 code with GPL-3 code, the GPL-2 code needs to be license under the GPL-2+ (v2 or later), or dual-licensed under the GPL-2 (v2 only) or GPL-3 (v3 only).[0] The mkgmap source files in question: src/uk/me/parabola/mkgmap/filters/MustSplitException.java src/uk/me/parabola/mkgmap/reader/MapReader.java The splitter source files in question: src/uk/me/parabola/splitter/tools/BitReader.java src/uk/me/parabola/splitter/tools/BitWriter.java test/func/ArgsTest.java test/func/Base.java test/func/SolverAndProblemGeneratorTest.java test/func/lib/Args.java test/func/lib/Outputs.java test/func/lib/TestUtils.java test/uk/me/parabola/splitter/tools/TestBitReader.java Steve & Gerd, can you relicense the code to GPL-2+ (v2 or later) or dual license those files as GPL-2 (v2 only) or GPL-3 (v3 only)?

Hi Bas, as I wrote before I don't care much about the licence. I have no idea what to change. Maybe you can post a patch?

What needs to change is the license header in the various files.

Hi, I am not sure what to do here. The splitter sources in question are copies or modified copies of sources in mkgmap. Why do they cause problems in splitter, but not in mkgmap? The source src/uk/me/parabola/mkgmap/reader/MapReader.java was changed recently but the copyright info is very old. Why does it cause problems now?

They are problematic in mkgmap too, they have simply not been noticed there before.

Because the new file in splitted showed up in my license & copyright review for the changes since SVN r548 (the previous revision in Debian). Ideally all the files in mkgmap and splitter are relicensed to GPL-2+ (v2 or later) to have the most widest license compatibility. Only the copyright holders can change the license, so this is something you, Steve and the other copyright holders need to consent to.

Hi Bas, okay, I see no problem to change to GPL-2+ for sources written by me, but if that also means we need permissions from authors who did not post anything since many years you can probably forget this. A quick check in mkgmap sources shows 297 java sources with GPL-3 or GPL-2+ licence and 273 with GPL-2 only. Most of the latter (236) are from Steve Ratcliffe or have no copyright section. Still a few show (inactive) copyright holders : Copyright 2009 Toby Speight Copyright (C) 2010 Jeffrey C. Ollie Copyright 2009 Clinton Gladstone Copyright (C) 2009 Christian Gawron Gerd Sebastiaan Couwenberg wrote

Yes, hunting down past contributors is a problem with relicensing. Alternatively GPL-3 (v3 only) sources must be kept out of mkgmap & splitter, because that introduces the license incompatibility with the many GPL-2 (v2 only) sources. Kind Regards, Bas

The license issue still persists in the mkgmap & splitter source. Mostly in files for which you are the primary author. Can your relicense the GPL-2 (v2 only) and GPL-3 (v3 only) sources to allow both licenses? Mixing GPL-3 (v3 only) sources in a project with GPL-2 (v2 only) sources is not possible, and makes the work unredistributable. If this issue persist I'm forced to remove the mkgmap & splitter packages from Debian & Ubuntu which is not in the interest of our users.
