Hi,

I cannot checkout from a cloned git repository I have created. I am using git 0.99.5 from Gentoo portage.

Following the tutorial, I create new git repository:

  $ mkdir git-test
  $ cd git-test/
  $ git-init-db
  defaulting to local storage area
  $ echo "Hello, Git" > hello
  $ git-update-cache --add hello
  $ git-write-tree
  4bd2134df7a908d2764f70d155e32650954cfc72
  $ echo "Initial commit" | git-commit-tree
4bd2134df7a908d2764f70d155e32650954cfc72 > .git/HEAD
  Committing initial tree 4bd2134df7a908d2764f70d155e32650954cfc72

Now on the server, I create a repository:

  $ mkdir git-test.git
  GIT_DIR=git-test.git/ git-init-db

Then I push my local repository to remote server like this:

  $ git push ssh.remote.server:/home/penberg/public_html/git-test.git master
  Password:
  updating 'refs/heads/master'
    from 0000000000000000000000000000000000000000
    to   8744316e49411509ba28e9cf567f3aec5833ec74
  Packing 3 objects
  Unpacking 3 objects
   100% (3/3) done
  refs/heads/master: 0000000000000000000000000000000000000000 ->
8744316e49411509ba28e9cf567f3aec5833ec74

After which I clone the newly created repository like this:

  $ git clone http://www.remote.server/~penberg/git-test.git cloned
  defaulting to local storage area
  Somebody should define smarter http server protocol

Now, the problem is that checkout does not work:

  $ git checkout
  usage: git-read-tree (<sha> | -m [-u] <sha1> [<sha2> [<sha3>]])

That's because I have no HEAD:

  $ ls -l .git/HEAD
  lrwxrwxrwx  1 penberg users 17 Sep  2 14:07 .git/HEAD -> refs/heads/master

  $ ls -l .git/refs/heads/
  total 0

What am I doing wrong here? Doing a git pull causes the following error:

  $ git pull http://www.remote.server/~penberg/git-test.git
  Fetching HEAD from http://www.remote.server/~penberg/git-test.git using http
  got 8744316e49411509ba28e9cf567f3aec5833ec74

You would need 'chmod +x git-test.git/hooks/post-update' here if you are allowing people to pull over http from this repository.

I just realized that where this was documented was quite obscure in the tutorial. I'll update it with the appended patch.

The problem is that 'git clone' does not support cloning over http from servers that are not properly prepared. This 'git clone' exited with non-zero status with an error message, didn't it?

-->8-- -->8-- -->8-- Mention post-update when we first talk about publishing a repository.

There is more detailed instruction for `project lead` later in the tutorial to talk about the same, but at this point in the flow of tutorial, the first time reader has no way of knowing it.

Aah, thanks! That fixed it for me.

I double checked that -- no, it does not print out an error. I copied the exact output in the original mail.

How about "must do chmod before pushing anything to this repository"? I think I tried chmod at some point but always did it too late (i.e. after the initial push).

Which ended with the error message "Somebody should define smarter http server protocol". That's from git-clone-script and the echo to generate the output is followed by "exit 1".

I think "at this point" in the flow of tutorial text would be explicit enough, but I am not very good at writing documentation, so rewording/clarifying patches are always welcome.

You could always run git-update-server-info manually after pushing if you forgot to enable the hook. If you are paranoid you could run it with '-f' flag to rebuild the info from scratch.

Oh, I just didn't realize that was an error message. Perhaps it could have an "Error" prefix and an explanation that the repository was not cloned properly.

Anyway, thanks for the help!
