Question

Is there any way to filter a git log to the commits specific to a fork, given it didn’t keep the upstream tags? If so, how can it be done?

For example, I want to know what are the commits in the Samsung Linux kernel fork didn’t come from the Torvalds Linux kernel tree.

Thank you,

Rafael

Well, you would need to have all commits from both repositories in a single local repository. Then you need to know the head commits of both repositories.

git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
cd linux
git remote add -f samsung git://android.git.kernel.org/kernel/samsung.git

After you’ve done this, it’s simple.
Ask git to provide a log of “reachable from samsung, but not reachable from Linus’ tree”:

git log origin/master..samsung/master
# which is equivalent to
git log ^origin/master samsung/master
# and
git log samsung/master --not origin/master
