I'm understanding this just as I read this, but it seems that implementing a git snapshot (I'm myself interested), could be done quickly with a new git. (When was git stash create introduced? I don't know it?)

Something like this: cp .git/index .git/tmp-index GIT_INDEX_FILE=.git/tmp-index git add -N . git stash create

So we use add -N to put all files into tracked but unstaged by default, but we keep our old index. Now stash is ready to save off the working directory, and further logic has to be applied on the returned commit to save it off..

Ok I didn't test this. Stash creation fails because the add -N status is not quite "tracked but no content staged", but rather you _have_ to stage the files at a later point. git add -N is just a reminder thing?

Error output: plugin-gui.log: not added yet fatal: git-write-tree: error building trees Cannot save the current index state

Shame, I wish the above script worked.

I did the initial git-stash at the end of June 2007; git-stash create was done by Junio about a week later and was released as a part of v1.5.4.

git-add -N came much later, late August 2008, and is available only in v1.6.1 and later.

I think you want to export GIT_INDEX_FILE you set to the temporary file before running these two commands.
