I use transmission constantly and would be happy to sponsor. In principle of course: assuming there are no technical show-stoppers.
I already have my own fork on salsa.debian.org/bap/transmission with some very minor tweaks. In the meantime, I note that Sandro Tosi has dropped his maintainership of the package, but pushed a debian/4.0.5-2 tag without uploading. Do you know the status of that? The two top bugs are a missing -latomic on ARM, which should be easy enough to work around in debian/rules using include /usr/share/dpkg/architecture.mk if ... and the prebuilt javascript business, which I note from MR/16 you've been working on. One suggestion I have for that is to set things up so that *if* the tools are available, the javascript can be rebuilt; but if not, pre-built versions are used anyway. This would make things robust, and would I think allow the bug to be downgraded. I'm also not thrilled with how the build process adds a git hook if it can. Should probably hot-wire that off, because it seems to present a potential security issue. Just a quilt patch to disable the entire if(GIT_FOUND) thing at the end of CMakeLists.txt seems about right. (The Source Control System is supposed to control the build, not vice versa!) Anyway, let me know if/when you want me to dput. Cheers, --Barak.
