Please see: https://github.com/google/syzkaller/blob/master/docs/syzbot.md#testing-patches for formats. In all formats a git tree is not enough. And it is not enough to identify code state in any other context too, it's always git repo + branch or commit hash. >> syzbot tried to test the proposed patch but build/boot failed: >> >> failed to checkout kernel repo https://github.com/google/kmsan.git/---: >> failed to run /usr/bin/git [git fetch https://github.com/google/kmsan.git >> ---]: exit status 129 >> error: unknown option `-' >> usage: git fetch [<options>] [<repository> [<refspec>...]] >> or: git fetch [<options>] <group> >> or: git fetch --multiple [<options>] [(<repository> | <group>)...] >> or: git fetch --all [<options>] >> >> -v, --verbose be more verbose >> -q, --quiet be more quiet >> --all fetch from all remotes >> -a, --append append to .git/FETCH_HEAD instead of overwriting >> --upload-pack <path> path to upload pack on remote end >> -f, --force force overwrite of local branch >> -m, --multiple fetch from multiple remotes >> -t, --tags fetch all tags and associated objects >> -n do not fetch all tags (--no-tags) >> -p, --prune prune remote-tracking branches no longer on >> remote --recurse-submodules[=<on-demand>] >> control recursive fetching of submodules >> --dry-run dry run >> -k, --keep keep downloaded pack >> -u, --update-head-ok allow updating of HEAD ref >> --progress force progress reporting >> --depth <depth> deepen history of shallow clone >> --unshallow convert to a complete repository >> --update-shallow accept refs that update .git/shallow >> --refmap <refmap> specify fetch refmap >> >> >> >> >> Tested on: >> >> commit: [unknown] >> git tree: https://github.com/google/kmsan.git/---> compiler: clang version 7.0.0 (trunk 334104) >> patch: https://syzkaller.appspot.com/x/patch.diff?x=1207511c400000 > > > Ciao > Stephan > > > -- > You received this message because you are subscribed to the Google Groups "syzkaller-bugs" group. > To unsubscribe from this group and stop receiving emails from it, send an email to syzkaller-bugs+unsubscribe@googlegroups.com. > To view this discussion on the web visit https://groups.google.com/d/msgid/syzkaller-bugs/1626520.Rx0128ICKU%40positron.chronox.de. > For more options, visit https://groups.google.com/d/optout.
