`diff3`

diff3 conflict is basically what you always want to see, either by setting it as the default as per stackoverflow.com/questions/27417656/should-diff3-be-default-conflictstyle-on-git:

git config --global merge.conflictstyle diff3

or as a one off:

git checkout --conflict=diff3

With this, conflicts now show up as:

++<<<<<<< HEAD
 +5
++||||||| parent of 7b0f59d (6)
++3
++=======
+ 6
++>>>>>>> 7b0f59d (6)

7b0f59d is the SHA-2 of commit 6.

instead of the inferior default:

++<<<<<<< ours
 +5
++=======
+ 6
++>>>>>>> theirs

We can also observe the current tree state during resolution:

* b4ec057 (HEAD, master) 5
* 0b37c1b 4
| * fbfbfe8 (my-feature) 7
| * 7b0f59d 6
|/
* 661cfab 3
* 6d748a9 2
* c5f8a2c 1

so we understand that we are now at 5 and that we are trying to apply our commit 6

So it is much clearer what is happening:

and so now we have to decide what the new code is that will put both of these together.

Let's say we decide it is 5 + 6 = 11 and continue rebasing:

git add .
git rebase --continue

We now reach:

++<<<<<<< HEAD
 +11
++||||||| parent of fbfbfe8 (7)
++6
++=======
+ 7
++>>>>>>> fbfbfe8 (7)

and the tree looks like:

* ca7f7ff (HEAD) 6
* b4ec057 (master) 5
* 0b37c1b 4
| * fbfbfe8 (my-feature) 7
| * 7b0f59d 6
|/
* 661cfab 3
* 6d748a9 2
* c5f8a2c 1

So we understand that:

and after resolving that one we now reach:

* e1aaf20 (HEAD -> my-feature) 7
* ca7f7ff 6
* b4ec057 (master) 5
* 0b37c1b 4
* 661cfab 3
* 6d748a9 2
* c5f8a2c 1
