git pull and GIT_DIR

git pull and GIT_DIR

[bill lam]

It appeared that

a)
cd /path/to && git pull git/https://....

will fetch and checkout latest changes to working tree.  This is as
expected.  On the contrary

b)
GIT_DIR=/path/to/.git git pull git/https://....

will only update git repo, but leaving working tree untouched.
Subsequent git status and git diff will indicate unstaged changes, 
apparently a commit that will revert the updated git repo. I have to
do 'git reset --hard' to really update the working three.

I'm not sure if this is an intended behavior or I missed something.

-ETOOLITTLEINFO.

When you do b)

 - is /path/to the working tree for /path/to/.git?

 - where is your $(pwd)?

 - if your $(pwd) is different from /path/to, how are you telling git
   where the working tree is?  are you using GIT_WORK_TREE or something?

It is non-bare and /path/to is the working tree.  The git pull was
run inside a shell and $(pwd) is $HOME.  GIT_WORK_TREE is not used.
This let me remember that there were some directories/files checkout
under $HOME that should be under /path/to.  I might recall
incorrectly, but does it mean that it need to use the form

GIT_DIR=/path/to/.git GIT_WORK_TREE=/path/to git pull url

to make it to the samething as

cd /path/to && git pull url
