Checkout to different directory at certain commit without changing index

Checkout to different directory at certain commit without changing index

[Ondra Medek]

Hello,
I need a simple script for unskilled users to do a fast checkout (LFS
friendly) of the current local Git clone at a certain commit to a
different directory I.e. something like "copy at a point in history".
IMO all possible solutions are summarized in this thread
https://stackoverflow.com/questions/160608/do-a-git-export-like-svn-export
I describe some of them with my remarks:

- git checkout-index : works with HEAD only.
- git archive: influenced by export-ignore and export-subst
attributes, so may not produce exact copy of sources. (And needs tar).
- git worktree add -d : needs cleanup: git prune or git remove.
- git clone: Unfortunately, -b param cannot work with commit hash and
does not respect local worktree settings (e.g. autocrlf). So, a
solution may be a bit complicated: git clone -s -n . dest/path ; cp
.git/config dest/path/.git ; cd dest/path ; git co -q <commit-ish> ;
rm -rf .git
- git checkout: Unfortunately, modifies Git index, so some action to
revert index is necessary after: git --work-tree=/path/to/checkout/
checkout -f -q <tree-ish> -- ./

For me, the best solution is with git clone, because it does not
modify Git index nor any source working tree settings, so no cleanup
is necessary. But it's a bit complicated, though. It seems to me that
"git checkout" could do this better and simpler if it would have some
param to not modify the Git index. Is it possible to enhance git
checkout? Or is there any other simple solution not mentioned in the
SO thread?

Thank you

I think using

     git archive "$commit" --format=tar |
        { cd "$output_directory" && tar -xf -; }

is probably the simplest solution. If you don't want to rely on tar then 
something like

     GIT_DIR="$(git rev-parse --path-format=absolute --git-dir)" &&
     GIT_COMMON_DIR="$(git rev-parse --path-format=absolute 
--git-common-dir)" || exit
     GIT_INDEX_FILE="$GIT_DIR/tmp-index-$$"
     export GIT_DIR GIT_COMMON_DIR GIT_INDEX_FILE
     unset GIT_WORK_TREE
     mkdir "$output_directory" && cd "$output_directory" &&
     git read-tree -u "$commit"
     status=$?
     rm "$GIT_INDEX_FILE"
     exit $status

Which uses a temporary index file should work (note I haven't tested 
it). You may want to add "--recurse-submodules" and/or 
"--no-sparse-checkout" to the "git read-tree" commandline.

Re: Checkout to different directory at certain commit without changing index

[Ondra Medek]

Hi Phillip,

besides dependency on tar, I do not want to use git-archive because
it's influenced by export-ignore and export-subst attributes, too (as
I have mentioned).

Thanks for git read-tree, seems it's exactly what I need. Just git
read-tree has complained that -u switch needs -m or --reset switches.
And I have simplified it to

git --work-tree="$destdir" read-tree --index-output="$destdir".git -u
--reset "$commit"
rm -f "$destdir"/.git

May I post this solution to the SO thread I have mentioned?

Thanks very much

Re: Checkout to different directory at certain commit without changing index

[Ondra Medek]

Hi Phillip,

your trick with different index file works with git checkout, too, e.g.

GIT_INDEX_FILE="$destdir"/.git git --work-tree="$destdir" checkout -f
-q "$commit" -- ./
rm -f "$destdir"/.git

Sincerely
Ondra

Sorry I'd forgotten about that

You should be aware that --reset will happily overwrite files in the 
destination directory, using -m instead would stop existing files being 
overwritten. If you change to -m you must set GIT_INDEX_FILE instead of 
using --index-output otherwise only the files that differ from the 
current index will be checked out. Also using a relative path for the 
index file specified with --index-output or GIT_INDEX_FILE is error 
prone when running the command from a subdirectory of the repository. I 
avoided suggesting --work-tree because I wasn't sure how it handled 
relative paths when run from a subdirectory but I think it is in fact ok.

That's entirely up to you but I'd make sure it works with relative paths 
and note the difference between --reset and -m.

I'd not thought of that, presumably "git restore" would work as well. 
Using "./" means it will only work from the repository root, you can use 
the pathmagic ":/" instead to checkout everything when it is run from a 
subdirectory  but you need to make sure GIT_INDEX_FILE is an absolute path.
