diff doesn't work for first commit

[ylecuyer]

Because of this line:

ungit/source/git-promise.js

Line 288 in 2aae26a

return git(newFileDiffArgs, repoPath, true);

If you want to see the diff of the very first commit of a git repo you will see the current file content instead of the original one.

I remember having an issue with the very first commit of a new repo as ungit try to compare with previous commit that doesn't exist.

I don't remember if I ever fixed it, but will fix it

[jung-kim]

It seems to be working... Can you tell me how I can replicate?

[ylecuyer]

You have to add another commit and modify the file to reproduce the error

[jung-kim]

Ah Okay, will retest later and reevaluate

[ylecuyer]

This also happens if you look for an old commit and locally modify the same file as one in the commit. Then the diff for the select file in the commit will show the current file content

[jung-kim]

It seems that I can see the 2nd and 1st commit...? are you at a particular screen dimension?

[ylecuyer]

I have found a way to reproduce:

cd ~
mkdir ungit-temp
cd ungit-temp
git init
echo "a" > text.txt
git add -A
git commit -m "commit"

Everything is OK

Revert the commit

Everything is OK

Check the first commit

NOT OK should be +a (though the +1/-0 is ok on top)

echo "b" > text.txt

Stage

Everything is OK

Reverted commit

NOT OK should be - a (+0/-1 is ok on top though)

Initial commit

NOT OK should be - a (+1/-0 is ok on top though)

git add -A
git commit -m "change"

New commit

Everything is OK

Reverted commit

Went back to is OK

Initial commit

Still not OK (should be + a)
