将git repo移动到另一台服务器

Question

I have a git clone/repo on a development server, but I am now moving to another one. I don't want to commit all my local branches and changes to the main repository, so how can I make an exact copy of everything on oldserver to newserver?

I tried oldserver:~$ scp -rp project newserver:~/project

but then I just get loads and loads of "typechange" errors when trying to do anything on newserver.

Someone said something about x-modes, but how can I preserve that when moving files between servers?

Answer 1

If you want a git solution, you could try

git clone --mirror <oldurl> <newurl>

though this is only for bare repositories.

If this is a non-bare repo, you could also do the normal clone, followed by something like this:

git fetch origin
git branch -r | grep '^ *origin/[^ ]*$' |
    while read rb; do git branch --no-track ${rb#*/} $rb; done
git remote rm origin

The middle step can of course be done in 5000 different ways, but that's one! (note that the continuation line \\ isn't necessary after the pipe in bash - it knows it needs more input)

Finally, I'd suggest using rsync instead of scp (probably with -avz options?) if you want to directly copy. (What exactly are these typechange errors?)

Answer 2

I've actually done this, and all I did was tar the repo up first and scp it over. I would think that scp -rp would work as well.

"Typechange" would normally refer to things like a symlink becoming a file or vice-versa. Are the two servers running the same OS?

Answer 3

You may also want to try the simple dumb solution -- don't worry about how the typechanges got there, but let git fix them with a reset command:

git reset --hard HEAD

That only makes sense if (1) the problems all pertain to the checked-out files (and not the repository structure itself) and (2) you haven't made any changes on newserver which you need to preserve.

Given those caveats, it worked for me when I found myself with the same problem, and it doesn't require you to think about git's internals or how well your file-transfer process is preserving attributes.
