The idea: use `git checkout-index` with a relocated work tree (something like the result of running `mktemp -d /tmp/gitXXXXXX`) and build there. This will basically replace step 0 and remove steps 1,3-5. Basically, you'd do: DIR=`mktemp -d /tmp/gitXXXXXX` trap "rm -rf '$DIR'" TERM INT EXIT git --work-tree="$DIR" checkout-index --all make test -C "$DIR" The question is: why are you concerned with the state of the file representing the index at all? As I've already hinted, the behaviour of the index file during committing appears to be not documented which means Git is free to actually update the index when it records a commit. So what would maintaining the index's file mtime etc would buy you? -- You received this message because you are subscribed to the Google Groups "Git for human beings" group.
