git shallow clone (clone –depth) misses remote branches

After cloning a remote repository it does not show any remote branch by -a option. What could be the problem? How to debug it? In this snippet two of the remote branches are not shown:

$ git clone --depth 1 git://git.savannah.gnu.org/pythonwebkit.git
$ cd pythonwebkit
$ git branch -a
* master
  remotes/origin/HEAD -> origin/master
  remotes/origin/master
$ git --version
git version 1.8.3.1

Tried the same command on another machine, it works well:

$ git clone --depth 1 git://git.savannah.gnu.org/pythonwebkit.git
Receiving objects: 100% (186886/186886), 818.91 MiB | 3.44 MiB/s, done.
$ cd pythonwebkit/
$ git branch -a
* master
  remotes/origin/HEAD -> origin/master
  remotes/origin/debian
  remotes/origin/master
  remotes/origin/python_codegen
$ git --version
git version 1.7.1

Tried also cloning another repo, it works well. Though I can try it on this machine again, but it would be better to know what’s wrong.

Any suggestions or hints will be more than welcome.

Edit: Answer summary: Since git version 1.8.3.2 the “–depth” and “–no-single-branch” need to be used together to get the same behavior as before. This is deemed a bug fix.

    The behavior is correct, after the last revision the master-branch is (since this is the primary remote’s HEAD) the only remote-branch in the repository:

    florianb$ git branch -a
            * master
              remotes/origin/HEAD -> origin/master
              remotes/origin/master
    

    The full clone offers new (all) branches:

    florianb$ git branch -a
            * master
              remotes/origin/HEAD -> origin/master
              remotes/origin/debian
              remotes/origin/master
              remotes/origin/python_codegen
    

    Shallow clones

    Due to the shallow-description in the technical documentation, a “git-clone --depth 20 repo […] result[s in] commit chains with a length of at most 20.” A shallow clone therefore should contain the requested depth of commits, from the tip of a branch.

    As – in addition – the documentation of git clone for the --single-branch-option describes:

    “Clone only the history leading to the tip of a single branch, either specified by the --branch option or the primary branch remote’s HEAD points at. When creating a shallow clone with the --depth option, this is the default, unless --no-single-branch is given to fetch the histories near the tips of all branches.

    Therefore a shallow clone (with the depth-option) only fetches only one single branch (at your requested depth).


    Unfortunately both options (--depth and --single-branch) have been faulty in the past and the use of shallow clones implicits unresolved problems (as you can read in the link I posted above), which is caused by the given history-rewrite. This leads in overall to somewhat complicated behavior in special cases.

    After I’ve done the shallow clone,
    to be able to checkout other branches from remote,

    1. I edit the file from .git/config:

      fetch = +refs/heads/master:refs/remotes/origin/master
      

      and change it to

      fetch = +refs/heads/*:refs/remotes/origin/*
      
    2. After that, I do a git fetch -vvv

    3. Finally git checkout the-branch-i-ve-been-looking-for

    Update:

    Also by using @jthill’s solution on the comment,

    git remote set-branches origin '*'
    

    will have same effect as step 1. After that, proceed to step 2 and 3.

    From reading the responses and the comment from @jthill, the thing that worked best for me was to use the set-branches option on the git remote command:

    $ git clone --depth 1 https://github.com/dogescript/dogescript.git
    $ git remote set-branches origin 'remote_branch_name'
    $ git fetch --depth 1 origin remote_branch_name
    $ git checkout remote_branch_name
    

    This changes the list of branches tracked by the named remote so that we can fetch and checkout just the required branch.
