Wolfgang,

I'm trying to figure out what I'm doing wrong trying to sync my local x86
repo as per the 'new' instructions on the wiki. This is what I get:

graeme at helios:~/Source/U-Boot/x86$ git rebase ${upstream}/master
fatal: Needed a single revision
invalid upstream u-boot/master

Any idea?

Regards,

Graeme

I did not write (and actually not even read yet) these new
instructions, so I cannot comment on this.

(answering from my non-U-boot address)

I did write the changes, and I think I did post an announcement on the 
U-Boot list about it.

Re: Greame's problem:

I should have made it clear that '${upstream}' is just a way to 
represent the upstream tree, either u-boot or u-boot-arm. The actual 
command for x86 should thus be

	git rebase u-boot/master

(or whatever name you gave to the upstream tree remote)

Alternatively, one could do

	setenv upstream u-boot
or
	set upstream=u-boot

depending on the shell used.

I'll amend the Wiki pages to make that clear.

I was already clear on that - I had set upstream=u-boot - Note the error
message:

fatal: Needed a single revision
invalid upstream u-boot/master
                 ^^^^^^
I think the problem is at:

git fetch git://git.denx.de/${upstream}.git

Where are we actually pulling the upstream tree into?

No my repo is at ~/Source/U-Boot/x86/ and I have uboot and master branches
there (as per previous wiki instructions) so I tried:

git checkout uboot
git fetch git://git.denx.de/${upstream}.git
git checkout master
git rebase ${upstream}/master

But that is not right - I would normally rebase to uboot

I think there is a missing link here somewhere

${upstream}/master needs to correspond to a remote tracking branch. Do you
have a remote named after ${upstream} ? ("git remote" prints them, "git
remote add <name> <url>" adds them). I think that might be the missing
link.

Quite often you'll have a remote called origin since that is created
automatically and points at the URL you cloned from. I guess a "normal"
workflow would be:

git checkout <local-branch>
git fetch <remote>
git rebase <remote>/master

Bye for now,

Sorry, from my non-U-Boot e-mail address I only had what Wolfgang quoted.

We are not pulling -- that's the point. We are fetching, i.e. we are 
importing all commits in the upstream remote and all its local branches 
will appear as remote branches to us.

That one (and actually the uboot branch itself) is unneeded.

No, you would not; you would rebase to your upstream's master.

The old instructions introduced a local branch called uboot which only 
served as a proxy for ${upstream}/master by regularly merging it (and 
these merges were actually always fast-forwards). So doing a rebase onto 
uboot is exactly the same as onto ${upstream}/master.

> I think there is a missing link here somewhere

I should have made my rationale clear when posting my update message on 
the list, sorry.

As I just said, uboot was just a placeholder for ${upstream}/master, and 
the old instructions kept it in sync through git merge although these 
merges were always fast-forwards by nature. What I did was remove uboot 
and use ${upstream}/master, and thus replace the pull into uboot by a 
simple fetch of ${upstream} directly, the net benefit being that there 
is now no git merge involved, hence zero risk of undue merges -- and 
I've seen such undue merges in the few last release cycles.

Amicalement,
