Unlike the file PKGBUILD, a patch file constitutes a modified source code because it does include some original code. No matter whether the modification is for use, or operation, or just even a typo fix, GPLV3 section 5 "Conveying Modified Source Versions" [1] doesn't distinguish them.
I had a similar experience in terms of the AUR package SGE. I put my source code modification into a single patch file and put it to AUR git. Without my modification, SGE won't work with latest Linux anymore. However, due to an AUR website bug confirmed by a TU, the package was taken over without any emails sent to me.
After a lot of back and force with the second maintainer, I finally gave up re-owning the package or making the software better within AUR. Instead I asked the second maintainer to add my name to the single patch file so I get the credit I deserve. However, the second maintainer denied that. He split the patch into many small patch files without my name in any of them, and insists that it is enough to have my name as the first AUR package maintainer. Then I asked him to remove my code modification, also was denied.
Then I tried to ask TU to remove the package many times, all TUs denied my request, except the last TU deleted all those small patch files after he understood this is a serious copyright violation issue.
Here is my understanding about those copyright conflicts. If you modified any source code, then GPL license will be applied, you have to copy the original copyright without any modification and then add yours, just as section 4 in GPL v3 says "You may convey verbatim copies of the Program's source code as you receive it"
It is understandable that many AUR maintainers, or programmers like myself, don't know the details and often violates some copyright law more or less. We are lucky that most upstream programmers don't mind it. But, should such issue arise, I would do my best to make the upstream programmer happy or just find another alternative software.
I know I am the minority in this list because the AUR SGE got two up- votes ironically after it didn't work anymore, and the second maintainer is even promoting the binary version based on my modification on some other repos. But, life is too short, I can live with it. I am writing this email because I just hope my painful experience can help this list know copyright better.
I think that's a valid angle to bring up!
FWIW, https://en.wikipedia.org/wiki/ROM_hacking#Distribution and https://en.wikipedia.org/wiki/Unofficial_patch#Law may be of interest. If a litigious company like Nintendo hasn't gotten courts to stamp out romhack patches I'm not sure this little software project poses any threat...
The upstream developer merely has an axe to grind against those that don't take openly-available code and use it in ways they intend. To that end, beating their chest with vague legal threats is an attempt at dominance rather than any pursuance of legal justice.
Very interesting links! I learned a lot. Here is my understanding after reading the two links. In terms of the first link about 'Rom Hacking', I would guess, if the Rom patch tool uses something like dd, especially if it is something like 'dd seek=', then the Rom patch doesn't use anything from the original Rom. However, a patch file generated by diffing source code files is very different as it does use the original source code. In terms of the second link 'Unofficial_patch', the three cases are all about if the user can modify a system he owns, more like a 'right to fix' case, instead of how a user can distribute a modified source code. In the Nintendo case, Game Genie sells a tool to modify Nintendo, but I would guess the tool doesn't include any code from Nintendo. Going back to the initial issue about this email chain, I would guess the AUR maintainer can use 'dd' instead of 'diff'. But this will become ridiculous and I personally won't do that at all, no matter I am the package maintainer or the original programmer. Just my two cents. I know nothing about law. If someone end up in jail and point a finger to me, all I do is to visit him once to make fun of him. :) Best, Manhong
