In-Depth Information
When you start working with branches it is worth remembering that the operation of
switching branches is stored in a reflog. The commands:
$ git checkout doc
$ git checkout master
would result in the following output of
$ git reflog
entries:
23d9855 HEAD@{0}: checkout: moving from master to doc
7c9bc41 HEAD@{1}: checkout: moving from info to master
The
$ git pack-refs --all
command packs all the references stored in
.git/refs/heads
and stores them in the
.git/packed-refs
file. You can un-
pack each branch by creating new commits in it.
5-2. Cloning a repository with branches
Problem
You want to create the exact copy of the repository created in Recipe 5-1. You expect
the copy to contain all the branches stored in the original repository:
master
,
doc
,
and
info
. You also want to create two new branches named
foo
and
bar
—they
should point to the same revision as
master
branch.
You will have to deal with difficulties caused by the behavior of the
$ git
clone
command: the cloned repository contains only one local branch named
mas-
ter
. During cloning git only creates one local branch for a branch that is stored in .git/
HEAD in an original repository.
Solution
Clone the repository created in Recipe 5-1 using the following commands:
$ cd git-recipes
$ git clone 05-01 05-02
$ cd 05-02
