0003237Doomseeker[All Projects] Bugpublic2017-09-01 13:282019-06-23 02:33
Assigned ToWubTheCaptain 
Platformx86_64 (really cross-platform)OSDebian GNU/LinuxOS Versionbuster/sid
Product Version1.1 
Target Version1.2Fixed in Version1.2 
Summary0003237: Non-free files and copyright issues in source archive
DescriptionTo create package suitable for inclusion in Debian GNU/Linux, much of Doomseeker's source code needs to be omitted, patched and/or repackaged without files which don't come with a copyright or license notice to meet Debian Free Software Guidelines (DFSG). There are also non-free files or files without copyright/license notice, which is a blocker for redistributing packages.

Arguably it's unsafe to assume everything to be under GPLv2(+) without explicitly stating so, and also impossible to tell if a source file is under "GPLv2 only" or "GPLv2+" (any later version) without a license heading. The origins of each file must be known certainly for inclusion.

Not every file needs to be under GPLv2+ of course, only under a compatible license. GNU All-Permissive license is suitable for small README files, for example. For media files and such where metadata is not possible to attach, human-readable instructions of licensing in COPYING file or similar will do the work.

One concrete example: tools/ has no free license stated, but claims "(c) The Doomseeker Team 2016." (Whether this is enforceable or not is a different issue, depending on if "The Doomseeker Team" is a legal entity recognized by courts.)

Other issues: In some non-Berne convention countries, (c) or (C) alone may not be enough and may need to include the word "Copyright" or symbol ©. Lintian tag copyright-with-old-dh-make-debian-copyright.
Steps To Reproduce

  1. wget [^] # Retrieves the source archive

  2. tar xvfz doomseeker-1.1_src.tar.bz2 # Extracts the archive

  3. Use standard system utilities (see intro(1) man page) to browse and read the files.

  4. licensecheck --recursive ./ reproduces attached licensecheck.log.

  5. debmake -c reproduces debmake-c.log (may need to create Debian stub files with dh_make first).

Additional InformationAttached logs also have false positives, but many true positives too.

In example, the dependencies folder comes with binary Windows objects for bzip2 1.0.6 and zlib 1.2.3. The Debian package maintainer needs to repack a DFSG source archive without these objects for each release (which can be somewhat automated in debian/copyright Files-Excluded field).

I also found out there's no real documentation about Doomseeker's binaries being redistributable under GPLv3(+?) only, because of LGPLv3(+?) dependency on Qt5.

Quite the opposite, in fact: "This program is distributed under the terms of the GPL v2." in about dialog. Uh oh.

Doomseeker is GPLv2+, Wadseeker is LGPLv2.1+ so while the about page is wrong it is in the clear. I have no issues with fixing this although any chance you might have a link to an explanation of what makes LGPLv2.1 incompatible with LGPLv3? All I can find without digging into the text of the license itself is the statement that it is not. Which seems strange to me if I could mix it with 100% proprietary code, but not GPLv2/LGPLv2.1. Unless it's just a quirk with how the GPL requires that all code fit under its exact terms.

There might have been a miscommunication or misunderstanding. The Free Software Foundation has published a compatibility table: [^]

So if you want to use a library under LGPLv3 (Qt5), the combination (executable) should be ok under GPLv3. (No word on GPLv3+ and LGPLv3+, but I would assume the "or later" clause applies.)

Qt4 could be built with LGPL 2.1-mode and I tested I could still build Doomseeker 1.1 with Qt4. Thus Qt4 builds can remain under GPLv2+, while Qt5 are GPLv3(+).

In regards to licenshecheck tool:

1. How do we satisfy the errors it prints for .png files or other images?

2. How do we satisfy the errors for code that is not ours?

2.1. Some of this belongs to bzip/zlib dependencies that can be statically linked into Doomseeker but also can be replaced by OS libraries: bzip/zlib. This code is actually forcefully statically linked in Windows builds because finding compatible, pre-built library versions on Windows is a nightmare born in hell.

2.2. There is some code that is used to build tools that are:

a) only needed during building and not distributed at all, or
b) distributed only on Windows as separate .exe files

2.3. lzma is "public domain", yet the tool spills out problems. Should we ignore that?

2.4. .ui and .ts files are generated by Qt tools.

2.5. doxygen.* files are generated by doxygen, albeit we can alter them pretty safely to add license header. But, should we? It was generated by a tool, even if it was later modified by hand.

2.6. ./src/core/CMakeFileListing.txt is a file that is generated by building tools.

3. tools/doomseeker-portable.bat is a one-liner. Do I need to add "rem" lines with GPL preamble there? This file is only needed on Windows, so probably not due to being out of scope for Debian.

4. What is the exact definition of done here? If I grep the licensecheck log file by UNKNOWN it spills out 1174 lines. Do we need to get this down to zero?

$ grep UNKNOWN licensecheck.log-1.txt | wc -l

If I grep out files that I believe should not be touched by us, I get a smaller list where most files I can agree need amending, however, how can I be sure that whatever I'll do will be satisfactory?

$ grep UNKNOWN licensecheck.log-1.txt | \
    grep -i -v \\.png | \
    grep -v tools/updateinstaller | \
    grep -v tools/updaterevision | \
    grep -v /lzma/ | \

Since the licensing in the source files indeed states that any "later" (L)GPL version can be used, we should probably amend all text that states that Doomseeker/Wadseeker is on (L)GPLv2(.1) and doesn't state "or later".

1. How do we satisfy the errors it prints for .png files or other images?

Those can be manually reviewed by the packager. As long as there's a notice somewhere stating everything under X is licensed under Y (or a COPYING file in that subdirectory), that's good enough for me. Some may interpret more broadly everything not explicitly stated to be under the project's license (GPLv2+/COPYING). Of course, it must a free license or else it may be excluded or replaced in Debian.

Quote from Zalewa
2. How do we satisfy the errors for code that is not ours?

Can you give an example?

If it can be satisfied with my answer to #1, that's fine. If it's non-free, then it should be replaced or removed (or if distribution permits, at most non-free archive in Debian). If it's non-essential to a Debian package, then it may be excluded in a DFSG release.

2.1. Some of this belongs to bzip/zlib dependencies that can be statically linked into Doomseeker but also can be replaced by OS libraries: bzip/zlib. This code is actually forcefully statically linked in Windows builds because finding compatible, pre-built library versions on Windows is a nightmare born in hell.

I have proposed at issue 0003238 to distribute those seperately (and create documentation how to acquire/build it on Windows). I'm not sure what exactly would need to be done to do this.

bzip2 license is somewhat similar to a BSD-license/zlib license and permits binary distributions sure. zlib is the same and compatible with GPL, but I believe the problem expressed here is the conflict with Debian's policy. The binaries without source can be excluded from a DFSG package in Debian, probably.

Quote from Zalewa
2.2. There is some code that is used to build tools that are

If make clean can remove it after build, that's fine for Debian I suppose. Not sure what the question (if any) was here.

Quote from Zalewa
2.3. lzma is "public domain", yet the tool spills out problems. Should we ignore that?

The code seems to be public domain, so it's a false positive in licensecheck. I can handle this manually. The documentation/specifications licensing is a bit more ambiguous: src/wadseeker/lzma/7zC.txt for example has this top heading and license text:

7z ANSI-C Decoder 9.35



7z ANSI-C Decoder is part of the LZMA SDK.
LZMA SDK is written and placed in the public domain by Igor Pavlov.

I would assume good faith of the creative mind behind the work and assume all of it to be under public domain without warranty expressions. I doubt it causes any problems for Debian, but if it does the specifications can be excluded in a DFSG release but the code will stay.

Quote from Zalewa
.ui and .ts files are generated by Qt tools.

This is a false positive too. Qt is free, so there's no issue with freedom. .ts files seem to be translations created by this project, so they're covered under Doomseeker's license (GPLv2+). Probably the same for .ui files:

Quote from LGPLv2.1
The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it).

A copyright notice (who authored the UI design/translations in what year) would be preferable to mention/document somewhere, although not a strict requirement. Mercurial commit logs may be enough for this.

Quote from Zalewa
2.5. doxygen.* files are generated by doxygen, albeit we can alter them pretty safely to add license header. But, should we? It was generated by a tool, even if it was later modified by hand.

See #1: An external COPYING notice is fine, a false positive in that case. Preferable if one can build the doxygen files from doxygen sources instead.

Quote from Zalewa
2.6. ./src/core/CMakeFileListing.txt is a file that is generated by building tools.

See previous.

Quote from Zalewa
tools/doomseeker-portable.bat is a one-liner.

A command to start the .exe executable with --portable flag is below threshold of originality, ineligible for copyright/public domain as stand-alone. False positive in such case.

Quote from Zalewa
What is the exact definition of done here? If I grep the licensecheck log file by UNKNOWN it spills out 1174 lines. Do we need to get this down to zero?

There's false positives, sure. Preferably do what you can for Doomseeker/Wadseeker sources, but it's not a strict requirement if the files are free. Doing so would at least make a package maintainer's life easier and avoid ambiguity for redistributors.

Autogenerated files probably don't need to be touched where not feasible.

Remove or replace whatever is non-free and can't be distributed under GPLv2+ from the main source code distribution.

Yes, I believe so. I believe else the non-source forms from build output will be distributable under GPLv2 or LGPLv2.1 only.

I will look further into this.

Doxygen source is GPLv2 with Qt exception. Whether Doomseeker or Doxygen's copyright applies to Doxygen files I'm not entirely sure, but for distribution it doesn't matter because the license is all the same.

I'll post a cleaned up licensecheck log once finished to better define "done" for this ticket.

licensecheck.problems-and-ambiguities.log is now available. An overview:

  • Some have real licenses or are ineligible for copyright, so I've removed them manually from the output.

  • Some things will be nuked from Debian DFSG package. Those are marked appropriately and should have consideration to be removed where possible.

  • media/icons/buddies.png seems to be non-free and should be replaced (unfortunately). Freedoom, anyone?

  • Exact sources for some media icons are missing. Some are ineligible for copyright. Flags are public domain.

  • Zalewa has some Doomseeker code in there with copyright notices but no permission for GPLv2+. Those are marked too.

  • media/slotstyles/marines/ I'm unsure, so I left it up for a question.

  • Core source has few files without copyright notice and no permission notice.

  • tools/updateinstaller/external/AnyOption/* is a non-free release, needs update to Expat released version.

  • tools/updateinstaller/external/verpatch/* is CPOL licensed, non-free. Must be removed.

  • tools/updateinstaller/external/win32cpp/* has more of this CPOL crap.

  • tools/updateinstaller/* in general is a pile of stinky poo I don't want to deal with. Code duplication (minizip), zlib contribs (removed in Debian), just a pain in the ass.

  • CMakeLists.txt files are probably copyrightable and manually crafted. [^]

Quote from "WubTheCaptain"
How's Windows binaries, are they legal?

Not in the clear, I would suspect, as one thing that is definitely missing is LICENSE file for the updater executable.

The update tool works like this:

1. As the "package maintainer", you build the complete software and `make install` it into a temporary directory. This prepares a full deployment of Doomseeker that you can now pack into a .zip file and redistribute to other computers. The program will run after extraction on any Windows XP or newer without any external dependencies needed - MSVC runtime DLLs are also provided in the package.

2. Mendeley Updater is also built and `make installed` as an "updater.exe" executable, which is bundled in Doomseeker package archive next to doomseeker.exe. We have altered Mendeley Updater's code to fit Doomseeker "theme", so: we changed the icon to Doomseeker's, the executable file metadata to state our ownership and also we changed some code because of problems. The customization alterations were done in accordance to the customization guidelines in Mendeley's [^]

2.1. No part of Mendeley Updater is linked with doomseeker.exe.

3. Mendeley Updater comes with 2 Ruby scripts - one of those came with the original Mendeley Updater, but had to be modified by us due to problems. The other script was authored by us. These scripts are not `make installed` or otherwisely linked with any part of Doomseeker and only serve the "package maintainer" to build the update packages. When you run these Ruby scripts, showing them the directory where you `make installed` Doomseeker, they prepare .zip archives and .xml description files that is understood and handled by Mendeley Updater. Each .zip gets an .xml. How many are there depends on 4.

4. There are additional .js files that contain JSON structure understood by those Ruby scripts. They are located in "tools/updateinstaller/tools/(win32|macosx)-configs" directories. These .js files describe which files go into which update package. We build several separate packages: the core program, 3rd party dependency DLLs (Qt, MSVC), Wadseeker and each plugin also has its own update package. This is done to a) preserve bandwidth and b) allow to omit updating plugins that the user doesn't have in the first place. As with 3., these .js files are not packaged into Doomseeker.

5. Each package mentioned in 3. is also listed in a single, generated update-info.js file. This file describes the newest versions of each package, their names and download URLs.

6. Once we build the packages and the update-info.js file we upload them to a special directory on our website. From this point users will see that there's a new update available.

Now, the update process works like this:

1. Doomseeker (as in doomseeker.exe) downloads the update-info.js file from our website.

2. It compares package versions from this file to package versions loaded in its process's memory.

3. If there are any discrepancies (yes, even if the version number in the file is lower than the installed one), it will offer the download. When download completes, Doomseeker will notify the user that restart is required to install the updates. Depending on user configuration this process might be fully or half-automatic.

4. Upon shutdown or next start of "doomseeker.exe", it is detected that an update is pending installation and "updater.exe" is called with appropriate command line arguments. The "updater.exe" needs to be first copied by Doomseeker into a temporary file itself and run from that temporary copy, because Windows forbids overwriting of executables or DLLs that are running as processes. Running that temporary copy allows "updater.exe" to overwrite itself.

5. "updater.exe" overwrites the installed files with files from the update packages and restarts "doomseeker.exe" with appropriate arguments. It can notify "doomseeker.exe" if installation was successful or not through command line arguments.

After some private discussion and contacting the few 3rd party contributors we have relicensed Doomseeker and all plugins to LGPLv2.1+ to remove any potential issues with library linking.

This relicensing caught me by surprise. The about dialog still makes no mention of "or any later version" though, so I'm not entirely sure what library linking we're talking about. (Qt is mentioned, but there may not have been an issue with Qt linking?) I'm not opposed, only curious.

I'll probably change it to read "or any later version" in the about page but kind of going back and forth on if that language even is meaningful in binary releases. With LGPL it shouldn't matter.

The relicense was done on principle rather than technical need. For awhile I've been believing that anything more restrictive than LGPL is too restrictive, and, while I don't want to put words in Zalewa's mouth, he shares similar feelings. Both of us typically release our other code under more permissive licenses like BSD. The fact that we could have, hypothetically speaking, been in a scenario where we were not able to upgrade Qt versions (i.e. if we were GPLv2 only) when that wouldn't have been our intention with the license is just the final straw.

Quote from Zalewa
If it's nevertheless necessary to include the copyright & license statement, will a small one or two-liner footnote at the end of the file be sufficient? Ie.

At least it works for licensecheck to detect LGPLv2.1+, but interpreting and following the LGPL license for documentation can be dodgy at best. If using the LGPL for documentation, it'd be best to also explicitly mention the LGPL's references to "object code" and "executables" to be interpreted as the output of any document formatting or typesetting system, including intermediate and printed output. That way, it's reusable in more formats other than plain text.

In other words, the LGPL wasn't really made for documentation and may create practical issues with corner-cases... probably not what you intended.

Here's GNU All Permissive:

  Copyright (C) <YEAR> The Doomseeker Team

  Copying and distribution of this file, with or without modification,
  are permitted in any medium without royalty provided the copyright
  notice and this notice are preserved.

Would this be a fine solution? licensecheck calls it "FSF All Permissive".

If you insist, I can trust your statement for it to be under LGPLv2.1+ despite the practical issues it may create for documentation. It will still be free for most uses.

Quote from Zalewa
Can we copyright or license Sonic's head in srb2.xpm?

I can't give legal advice, that's a question you'd want to ask about from a professional lawyer. However, I'd argue it should not violate the copyright of the original work. See [^] for applicability.

If in doubt, it's probably a good idea to ask the authors of those icons or replace them.

Quote from Zalewa
Part of Microsoft redist for Visual Studio 2008, but the original files in the actual redist have a bug that was never fixed by Microsoft and the program will not run with them.

No means of source to generate that file means a REJECT from ftp-masters in Debian, so it will be nuked in Debian. See "no source" in [^] . If applicable, see also "generated files" from the same FAQ.

I'm not sure if keeping this file in the archive creates issues for Doomseeker's LGPL2.1+ compliance or not, the intentions were good.

Quote from Zalewa

Ok on BSD like I've noted, but I wanted to make sure your changes to this file are also free. I was not really sure if your changes were GPLv2+/LGPLv2.1+ licensed or BSD, because it's not explicitly mentioned.

Quote from Zalewa
updaterevision tool is used for generating a header file and not redistributed in any form

Sorry, what are you trying to say here?

If you're trying to say updaterevision source doesn't need to be redistributed (in Debian source), omitting the directory results in a FTBFS (failure to build from source):

CMake Error at CMakeLists.txt:104 (add_subdirectory):
  add_subdirectory given source "tools/updaterevision" which is not an
  existing directory.

Commenting that CMakeLists.txt line 104 to bypass the CMake check subsequently fails during make:

make[2]: *** No rule to make target '../src/core/updaterevision', needed by 'src/core/CMakeFiles/revision_check'.  
CMakeFiles/Makefile2:160: recipe for target 'src/core/CMakeFiles/revision_check.dir/all' failed
make[1]: *** [src/core/CMakeFiles/revision_check.dir/all] Error 2

I didn't bother attempting to patch it any further for now.

I know inserting the svnrevision.h file to source tarball fixes the build. But that could be a "FTBFSIASW", resulting in a possible reject from ftp-masters.

Quote from Zalewa
Mendeley updater (updater.exe) source-code.

I know. Not all of Mendeley's dependencies seem to be DFSG-compatible however, so it will be nuked in Debian at least.

0003292 and 0003294 may give some pathway to remove Mendeley eventually. I know you seem to favor Mendeley, but I find it to be a burden for redistribution in the same source archive.

Besides, putting a copyright statement over what's essentially a directory listing does seem a bit excessive.

Agreed, I'd call it public domain. Just wanted to make sure.

Oh, and thanks for the cleanups and liberations so far.

Could you also make a small note where dependencies/* were downloaded from? "Source package missing source" in reject FAQ is a bit ambiguous, but I think it wants to make sure the convenience copies included are more or less identical to upstream.

According to READMEs, they are bzip2 1.0.6 and zlib 1.2.5. (Latest zlib upstream is 1.2.11 and 1.2.8 in Debian. It has had some security issues in the past, which caused headaches with Debian patching some convenience copies too.)

This should take care of most of the media files.

Doomguys and updaterevision remain to be dealt with.

As for .hgignore - it should probably be nuked from tarballs or any other source distribution that already strips the .hg directory. Same goes for .hgtags file.

The LGPLv2.1+ requires keeping intact all the notices that refer to that license and to the absence of any warranty. Thus,

Unless stated otherwise, all files listed here are under the LGPL v2.1 or later.

may not be sufficient (though the intent was good).

"These icons are free to use in both commercial products as well as personal use." has a bit of ambiguity on it in regard to right of redistribution, and it certainly makes no mention of creating derivative works (modifications).

They could be below threshold of originality and ineligible for copyright, but we probably have reasons to avoid that ambiguity with a replacement icon. For 0003246, having to go through debian-legal mailing list first to check for DFSG-compatibility would not be fun.

Legal trivia: Strictly speaking, Creative Commons licenses terminate automatically on failure to comply with the license (section 6(a) of CC BY-4.0).

To our benefit, – also similarly to the newer GNU licenses (e.g. LGPLv3, GPLv3, FDL 1.3) – CC BY-4.0 reinstates that right automatically "provided it is cured within 30 days of Your discovery of the violation". This would not have been the case with CC BY-3.0, which requires requesting express reinstatement from the licensor.

So, well done for prompt cure for Doomseeker 1.2.

Unfortunately this also means previous violations of CC BY-SA 3.0 or LGPLv2.1 may need express reinstantement from the licensor, if being pedantic about it. Dunno. 😕

There's src/wadseeker/lzma, public domain. Since you added notes for bzip2 and zlib convenience copies, could you please give a pointer where was this LZMA SDK downloaded from?

(Eventually I'd also like to know if it's replaceable with a Debian package like liblzma-dev. The build system may not currently support this, however.)

@Blzut3, what do you propose we should do with doomguys?

The buddies icon can be replaced with something neutral, although I find the current one quite charming and it will be sad to see it go.

The player slots... well, we always have blocks as a fallback, so we can just delete them, but it will be sad to see them go too.

Freedoom is BSD 3-clause and we can take the player sprite from it, but it's not as clean and distinctive as the original. In fact, it might be too noisy to be useful as an icon.

Blzut3 (administrator)

Probably the best way to handle them would be to go about supporting custom slot styles and icon replacements and turn it into a pure packaging issue. Obviously I'd like to keep our distribution as is, but I totally understand someone like Debian not wanting to distribute the non-free icons.

Either way a CMake flag would be needed, but another option would be just have the option change the buddies icon and disable the marines.

"marines" style is no longer baked into the executable and its installation has been made optional.


1. Introduce an idea of extra/custom player slot styles and load them from directories located in the "static data" file system paths.
2. Install the "marines" slot style as an aforementioned extra. This option is controlled by a new CMake option DOOMSEEKER_INSTALL_NONFREE, which defaults to "on" on Windows & Mac and to "off" on Linux. Thanks to this, the users who already use this style won't suddenly lose it, while at the same time it won't be baked into the executable anymore.
3. Added notices about the derivative pictures to media/SOURCES.txt.

If this is satisfactory, buddies.png will get the same treatment.

Thank you again, Zalewa.

A little odd for a public domain thing (updaterevision) to claim "Copyright (c)", but also place it into the public domain simultaneously. It's fine though, I get the intent.

There's hardly any original creativity in the marine slots but bot.png and player.png, so only the two are really non-free. open.png, specopen.png and spectator.png are fine, in my opinion: A mere simple shape or an idea of something is usually not copyrightable on its own.

The distribution of buddies.png and the two slot icons is still in the grey, and they'll be excluded in Debian distribution (except doomseeker-nonfree package as an extra if distribution permits). I suggest a "contrib" folder for buddies.png and marine slotstyles to make exclusion from source distribution easier.

Game engine icons:

  • Chocolate Doom icon is either GPLv2-only or GPLv2+. The chocolate ice cream cone was originally uploaded by another author on Flickr, but the copyright holder agreed to the same GPL license as the Chocolate Doom project. It is also missing the source for the right-side "D" in the icon ("preferred form of the work for making modifications to it"), thus strict GPLv2+ compliance seems not to be possible. [^]

  • Odamex icon is assumably GPLv2-only (for the lack of "any later version" clarification). Again, no GPL'd source that I can find. [^]

  • SRB2 icon is non-free and not redistributable without permission from Sega (copyright holders of Sonic the Hedgehog character).

  • Turok 2 EX icon is non-free(?) not redistributable without permission from Nightdive Studios.

  • Zandronum, dunno. Hard to find, but a quick uneducated guess may be Sleepycat (GPL + BSD).

Chocolate Doom and Odamex may be easy to fix by contacting the corresponding developers. Zandronum may be possible, but I don't know who to contact about the issue. SRB2 and Turok 2 EX may be difficult, as they are backed by corporates.

From Debian's standpoint, it must be possible to build a redistributable LGPL or GPL binary (DOOMSEEKER_INSTALL_NONFREE=NO?). Any binaries built with DOOMSEEKER_INSTALL_NONFREE are not redistributable as such (in conflict with Doomseeker's LGPLv2.1+ license and third-party GPL'd icons), but the source code may be.

Disclaimer: The above information consists of my current beliefs. No warranty any of the above information to be correct, it is not an endorsement.

I'll run a licensecheck a bit later. See 0003329 meanwhile.

The logos are going to have to be where the line is drawn as far as we are concerned. I'm not a lawyer, but I believe our usage falls under fair use of trademarks since they're used to identify services provided by the respective projects. So unless a lawyer says otherwise I think that's all in the clear (although SRB2 might be a little questionable, but that's more between Sega and SRB2 itself).

"Fair use" or "de minimis" defence argument may (or may not) be fine, I would at least make an effort to try as far as Debian Social Contract is concerned. Trademark sure, copyright is a bit more questionable.

For official Debian repositories (0003246), I'd prefer if there was a way to disable the non-free game engine icons from the resulting binary. I can understand if DRD Team will distribute non-free versions for Debian-based systems too with their apt repository.

Please reconsider.

Well the way I see it the icons are essential for the usability of the program, so they can't just be disabled. Replacing is strictly speaking possible, but is there really a user friendly option to replace them with? Or were you proposing an option to have none of the plugins built at all? (Yeah that last question was hyperbole since Chocolate Doom and Odamex are easy to clear.)

I'm not strictly against it, but presumably if pidgin-data can contain protocol logos in the main repo surely Doomseeker can?

While I was writing a note about Pidgin data, then I accidentally refreshed the page without having a copy and lost it. It has no Debian copyright file, is severely outdated with Debian Policy and most of the icons were simple shapes ineligible for copyright.

Okay, yeah. I sometimes forget the plugins are not baked into the executable but libraries linked at runtime, and Debian doesn't have to distribute all of them once.

I'd like to talk more about Sonic Robo Blast 2 (SRB2), and share my concerns with it too. If it's TL;DR, consider reading the last few paragraphs at least.

I have a concern SRB2 may be using unauthorized artistic works and characters under copyright from Sega, makes an interesting legal point for Doomseeker. I couldn't find USCO registration for Sonic the Hedgehog games/character or Sonic Generations, which could make statutory damage claims ineffective but not copyright infringement claims invalid. It is clear without doubt that the artistic works included in SRB2 are non-free. Freedom aside, I think there's a bit more to Doomseeker than a thought it to be "between Sega and SRB2 itself".

Though Doomseeker acts more like a server browser/search for SRB2 games, I consider it be an "act of communication" to the unlimited public audience to find multiplayer servers of SRB2.

This in itself would not be bad if the game was authorized, or official servers of an authorized multiplayer game would cease to operate. In contrast, Zandronum et. al require the original Doom 2 data to play (in favor of the copyright holders at id Software). Individual server hosts are responsible for what WADs and level of public access they convey, of course.

The SRB2 master server address is also included with Doomseeker's default configuration (a questionable thing), but if it was not to be included by default then Doomseeker might become more of a tool for private use and not a portal of access (a good thing).

In example, on 14 June 2017 the Court of Justice of the European Union (ECJ) published a press release named "Making available and managing an online platform for sharing copyright-protected works, such as ‘The Pirate Bay’, may constitute an infringement of copyright". Operating this kind of portal of access to infringements was held to be infringing, but the case was referred back to Netherlands' court for final decision in BREIN's case.

I've been talking more about European legislation, of course. Ideas are not generally copyrightable. Fair use in the United States... SRB2 is not fair use, in my opinion. The four criteria of fair use (17 U.S. Code § 107):

  1. the purpose and character of the use, including whether such use is of a commercial nature or is for nonprofit educational purposes;

  2. the nature of the copyrighted work;

  3. the amount and substantiality of the portion used in relation to the copyrighted work as a whole; and

  4. the effect of the use upon the potential market for or value of the copyrighted work.

In my view, SRB2 exploits the original works of Sega: It can or is likely harm the potential market of the original works, as replacements to the video games by Sega. This is point 4.

SRB2 does not seem to be seeking to profit from Sonic. This probably favors them for point 1 favorably or neutrally.

Point 2 (the nature of the copyrighted work) favors against SRB2. It's a fictional artistic work, in the sense that it is copyrightable. Facts and ideas are not copyrightable. A mere illusion of a clone game that reminds of the original Sonic games would be in favor of SRB2, but a fan-made Sonic game using Sonic artwork etc favors against SRB2.

Point 3: The works (the Sonic franchise characters, rings, textures) make up a substantial amount of SRB2 from what I've seen, nevermind the maps are original(?) in SRB2. This favors against or neutrally for them. SRB2 could've used original characters and passed it off as a game clone of Sonic, then it would've been in their favor or neutral.

It's not convincing from SRB2's legal page "no copyright infringement intended". That's something children say when they upload an unauthorized copy of a music track to YouTube to the wide public audience, "for entertainment purposes". (Don't do this.) Non-willful infringement does not waive the liability from reimbursing the copyright holder for infringements. In this case I suspect there to be reckless disregard for, or willful blindness to, the copyright holder's rights. SRB2 developers would have to refute evidence of willful infringement by establishing good faith belief in the innocence of its conduct but also show that it was reasonable to hold such belief. ( More so, "Sonic Team Junior is in no way affiliated with Sega or Sonic Team."

Opinions are my own, of course. Turok 2 EX is secondary to this SRB2 concern, because Turok 2 EX is a licensed game and they've been cooperating with Doomseeker developers to my awareness.

I would personally close 0002540 as "won't fix", remove SRB2 from core Doomseeker plugin distribution and let the SRB2 team ("Sonic Team Junior") know they would have to distribute it themselves if they're ready to take legal responsibility for it. This takes care of the SRB2 icon issue in Doomseeker too.

Alternatively, I would remove the SRB2 master server from Doomseeker sources. I don't prefer this option over complete removal of the plugin distribution, because in my view SRB2 should not exist in the way it currently does. Contributory infringement (secondary liability) is knowingly inducing, causing or materially contributing to the infringing conduct of another. (

I hope you can agree after reading this, and I'll be happy to answer to simple questions with my knowledge of copyright. I've already decided to not package SRB2 to Debian a long ago. Sorry for my difficulty to express a point across without my mess of thoughts.

If you really want to complain how much legal difficulty SRB2 produces, I think the place to bring this up is their forum, not here.

In 0002540 we were asked nicely to provide a plugin for the game. Normally, we'd rather prefer if this request was made to the port author - if they want a server browser, they should care. However, in this case, as the game is different than Doom, I thought that building this plugin would be beneficial to Plugin API - it would show us places where the API is still not generic enough. So I did it. Putting it in Doomseeker's repository was the sanest thing to do technically.

If companies were such dicks to torpedo each fan work, most of the pop-culture wouldn't be possible. Imagine lawyers going to Star Trek con and suing everyone who came in dressed in a Starfleet uniform. Neither possible would be stuff like this. How many incidents would be necessary to destroy the fandom and ruin the franchise?

If character's head and an IP address are insurmountable legal problems, then something is severely wrong with this civilization.

I see your points too.

The example video you linked is more likely to favor fair use with points 1, 3 and 4 at least. I make no large comment on the Star Trek con, but the argument does not seem to be a replacement to the original works nor harmful to the financial interests of the copyright holder, but in fact promotional in favor of the copyright holders. (Plus, at least common household objects are not copyrightable in the United States.)

I'll be doing a licensecheck later, as I said. Sorry I couldn't change your mind.

In regards to pidgin being a bad model due to the copyright file being unusual. Consider also that kopete and empathy-common similarly seem to ignore the issue. In those cases many of them seem to be redrawn but last I checked redrawing something to look identical to the source unless you do a side-by-side comparison doesn't get you out free.

Also in case you're wondering, we can't give free license rights to the Turok icon for obvious reasons (that would be relinquishing of trademark), however you could simply change the icon for free distribution. For example, circle crop this head:

Trademark and copyright are seperate rights, e.g. Apple Inc.'s logo is ineligible for copyright but still trademarked (non-copyright restrictions on use). I don't think a free copying license would affect rights about Turok negatively.

I'm not entirely convinced of the output from Intel's crc.exe to be copyrightable (the crc.cpp output), however Debian needs to be able to generate the binary crc.cpp from the software source and the source doesn't build on GNU/Linux (needs Microsoft's cl compiler). This and the non-free Turok icon means the Turok engine plugin would have to go to non-free repository in Debian, or not at all. I'll side with the latter, unfortunately.

Sidenote about the proposed dinosaur: CC BY-SA 2.5 is not transitively okay for Debian.

As for Doomseeker: Please consider including a copy of Intel's slice by 8 source with the Turok plugin for complete corresponding source code, despite the BSD licensing of itself.

On the subject of Turok's CRC:

I vaguely remember trying to figure out the values of the CRC in the Turok plugin to pinpoint what exactly is the source-code that generated them, but I couldn't. Since I've fallen asleep on this issue on several occasions now, I won't be spending any more time on this.

On the remaining subjects:

I actually lost track on what remains to be done. I'll have to retrace this whole issue.

Probably not much anymore. Lots of noise in the notes of this ticket, I may create child tickets later for any remaining issues.

I haven't tried packaging Doomseeker in a while, so I also haven't run the tooling to check for issues.

Right, status quo:

  • media/icons/buddies.png: ok, resolved (non-free theme also distributed, nope for Debian)
  • tools/updateinstaller/*: barely (not) ok? It's still "a pile of stinky poo". Code Project Open License – Wikipedia. Quick non-legal hunch is "yes, you can distribute it", but a big nope for Debian. Larger software distributions including the code can be "sold", but the dependencies itself cannot be. Cannot be sublicensed. Must include a copy of the license or an URI to it (section 5(e)) – not done yet?
  • CMakeLists.txt: ok, resolved.
  • lzma: ok (nope for Debian policy)
  • bzip2/zlib: ok (nope for Debian policy)
  • LGPL "later" clause: ok
  • Doxygen: ok?
  • icons: ok?
  • PSD icon: ok (nope for Debian policy)
  • Game logos: ok non-free "fair use"? (nope for Debian's policy?)
  • Fugue icons: ok, I believe CC BY-3.0 (author's website). No reply from the author for clarification.
  • SRB2: It's complicated. Not okay with me personally by legal hunch (and probably not okay from Debian's policy perspective), but fan art is a minefield... I personally don't believe SRB2 itself even pass the "fair use" test in United States, assuming it works as a replacement to Sega's other Sonic games (potential financial loss). Plugin code is our work which is ok and not copyright encumbered (afaik), however legal liability may exist (in some countries) for making access to infringement available (if I could claim infringement here). But there's no copyright infringement claim (yet)...
  • Turok (src/plugins/turok2ex/crc.cpp): ok with BSD-license inclusion (nope for Debian policy?)
  • MaxMind GeoLite2: ok on one condition: distributions of Doomseeker/Wadseeker with GeoLite2 (tarballs) must happen under conditions of GPLv3-only, due to one-way compatibility of CC BY-SA 4.0 to GPLv3. Else there'd be a violation of CC BY-SA 4.0 section 3, article (b)(3), of MaxMind's license. Compatible Licenses - Creative Commons Dunno on linking.

New tickets needed to clarify the situation and for decision making: 4+.

I think it might be nice to mention in the changelog how all (?) non-free files have been removed from this source release (e.g., CPOL stuff in 0003513).

All children are resolved or closed. I don't believe there are more remaining issues, unless I've missed something. (Non-free engine icons aside...)

Thanks to everyone involved for the big efforts to keep Doomseeker source code clean.
