introduce GIT_WORK_TREE to specify the work tree
setup_gdg is used as abbreviation for setup_git_directory_gently.
The work tree can be specified using the environment variable
GIT_WORK_TREE and the config option core.worktree (the environment
variable has precendence over the config option). Additionally
there is a command line option --work-tree which sets the
environment variable.
setup_gdg does the following now:
GIT_DIR unspecified
repository in .git directory
parent directory of the .git directory is used as work tree,
GIT_WORK_TREE is ignored
GIT_DIR unspecified
repository in cwd
GIT_DIR is set to cwd
see the cases with GIT_DIR specified what happens next and
also see the note below
GIT_DIR specified
GIT_WORK_TREE/core.worktree unspecified
cwd is used as work tree
GIT_DIR specified
GIT_WORK_TREE/core.worktree specified
the specified work tree is used
Note on the case where GIT_DIR is unspecified and repository is in cwd:
GIT_WORK_TREE is used but is_inside_git_dir is always true.
I did it this way because setup_gdg might be called multiple
times (e.g. when doing alias expansion) and in successive calls
setup_gdg should do the same thing every time.
Meaning of is_bare/is_inside_work_tree/is_inside_git_dir:
(1) is_bare_repository
A repository is bare if core.bare is true or core.bare is
unspecified and the name suggests it is bare (directory not
named .git). The bare option disables a few protective
checks which are useful with a working tree. Currently
this changes if a repository is bare:
updates of HEAD are allowed
git gc packs the refs
the reflog is disabled by default
(2) is_inside_work_tree
True if the cwd is inside the associated working tree (if there
is one), false otherwise.
(3) is_inside_git_dir
True if the cwd is inside the git directory, false otherwise.
Before this patch is_inside_git_dir was always true for bare
repositories.
When setup_gdg finds a repository git_config(git_default_config) is
always called. This ensure that is_bare_repository makes use of
core.bare and does not guess even though core.bare is specified.
inside_work_tree and inside_git_dir are set if setup_gdg finds a
repository. The is_inside_work_tree and is_inside_git_dir functions
will die if they are called before a successful call to setup_gdg.
