Git pull keeps deleting everything I've added

Question

I have a git repo (let's call it "default") with files A, B, and C. (I actually update others' modifications with svn.)

I clone that repo to "defaultmods" and add files D, E, and F.

I notice that someone updated A and C and added file G so I want those files updated and want the new file (G).

I go to my "defaultmods" repo and commit my changes. Then do a git pull from default. It deletes my files (D, E, and F) and leaves me with an exact working copy of default.

What I want is it to merge my stuff with the updated stuff giving me A, B, C, D, E, F, and G (with the updated A and C and new G file).

Am I missing something weird? Does it not work this way?

Answer 1

There must be something you're leaving out, because it does, in fact, worth this way:

$ mkdir default
$ cd default/
$ git init
Initialized empty Git repository in /Users/jim/Desktop/default/.git/
$ echo "A" > A; echo "B" > B; echo "C" > C
$ git add . && git commit -m "Initial commit"

 create mode 100644 A
 create mode 100644 B
 create mode 100644 C
$ cd ..
$ git clone ./default ./defaultmods
Initialized empty Git repository in /Users/jim/Desktop/defaultmods/.git/
$ cd defaultmods/
$ echo "D" > D; echo "E" > E; echo "F" > F
$ cd ../default
$ echo "A, updated" > A; echo "C, updated" > C; echo "G" > G
$ git add . && git commit -m "Upstream update"

Answer 2

You want: A, C and G. Do:

cd default
git pull [wherever A, C and G are located]
[resolve merges]

You now have A, C and G. Want it in defaultmods? Do:

cd defaultmods
git rebase ../default
[resolve merges]

Decide at this point you want to merge defaultmods into default? Do:

cd default
git merge ../defaultmods

Should be a clean one.
