It was basically the same as "git-rev-list", except:
- it output the date (as a raw number) in front, so pretty much everybody
ended up using "cut" to remove it, sometimes after sorting the output
numerically.
Sorting numerically is unnecessary with git-rev-list, since the output
is already sorted (not necessarily exactly by date, but by "recency"
and/or by other even stricter sorting rules)
- it was limited to a certain number of heads maximum (I forget, but I
think it was 16).
- it parsed the whole tree before outputting anything.
The git-changes-script was pretty broken.
You're _much_ better off doing it by:
- fetch the "remote" branch into the local repository. The
"git-changes-script" thing required that you fetch the remote branch
into _another_ repository, but still local. These days, just use a
local branch in the same repo.
So, for example, tracking my tree
export KERNEL=master.kernel.org:/pub/scm/linux/kernel/git/
git fetch $KERNEL/torvalds/linux-2.6 master:linus
which will just fetch my "master" branch into the local "linus" branch.
- then just do
git log linus..HEAD
and you'll see exactly what you wanted: what exists in your HEAD but
not in mine.
No complex script required.
Now, I've told some people that the diffstat is just the same (ie using a
simple "git diff linus..HEAD | git-apply --stat") but that was because
I've been muching some really awesomely bad 'shrooms. Clearly that doesn't
work well at all, since it will show all the stuff I have in my branch
reversed (since your head doesn't have it).
The way to get a diff is really to do a merge, and throw the merge away
after creating the diff. Ie something like this should work:
git checkout -b merge-branch
git merge "dummy merge" master linus &&
git-diff linus.. | git-apply --stat
git checkout -f master
git branch -D merge-branch
which will also tell you if the merge failed (in which case you might not
want to send me a "please pull", but instead try the merge locally and fix
it up, and then try again)
All of the above is obviously totally untested.
