According to git-config(1)
core.worktree
Set the path to the working tree. The value will not be used in combination with repositories found automatically in a
.git directory (i.e. $GIT_DIR is not set). This can be overridden by the GIT_WORK_TREE environment variable and the
--work-tree command line option. It can be a absolute path or relative path to the directory specified by --git-dir or
GIT_DIR. Note: If --git-dir or GIT_DIR are specified but none of --work-tree, GIT_WORK_TREE and core.worktree is
specified, the current working directory is regarded as the top directory of your working tree.
this setting is not used if GIT_DIR is set. But when I try it out
$ mkdir r1
$ mkdir r2
$ cd r2
$ git init
Initialized empty Git repository in /home/me/tmp/r2/.git/
$ date >f
$ git add f
$ git commit -m "f"
f
1 files changed, 1 insertions(+), 0 deletions(-)
create mode 100644 f
$ git status
# On branch master
nothing to commit (working directory clean)
=> Nothing interesting here. It comes here:
$ git config core.worktree $(cd ../r1;pwd)
$ git status
# On branch master
# Changed but not updated:
# (use "git add/rm <file>..." to update what will be committed)
# (use "git checkout -- <file>..." to discard changes in working directory)
#
# deleted: f
#
no changes added to commit (use "git add" and/or "git commit -a")
=> Seems the config is actually honored even though GIT_DIR is not set.
Bisect tells me 4f38f6b5bafb1f7f85c7b54d0bb0a0e977cd947c broke it. My main point is that I am
implementing this in JGit so I want the same behaviour. Question: Should we try to fix this
in git so it matches the documentation or fix the documentation to match behaviour.
The breakage appeared over a year ago and no one has complained.
