Unsupported new git status change code: [ A]

[jackbashford]

This occurs fairly frequently, I use direnv and this means I have .envrc files in my directories. However, running gs then gives me the message:

2025/02/13 15:43:23
Failed to decode git status change code for chunk: [ A .envrc]
Please file a bug including this error message as well as the output of:

git status --porcelain

You can file the bug at: https://github.com/mroth/scmpuff/issues/

Output of git status --porcelain:

?? .devenv/

Contents of .envrc are "use flake":

Interesting, the issue here is not the filename but rather the [ A] git status change code, which used to not exist but was seemingly added to git at some point. (In your porcelain example, it's crashing on the first file it encounters with that status).

From the git status documentation when scmpuff was written:

   X          Y     Meaning
   -------------------------------------------------
             [MD]   not updated

But currently I now see in the git status documentation (https://git-scm.com/docs/git-status#_short_format) that same status is possible with a A in the second field:

X          Y     Meaning
-------------------------------------------------
	 [AMD]   not updated

It should be relatively straightforward to update the parser to handle this case (though there are a bunch more new cases I see in that documentation too, so longer term #33 is probably the direction I'd like to update this project with), but I'm also curious how you get a git directory into the status where that code shows up, since I haven't encountered it before.

Here is a command log from me creating and having this issue:

$ mkdir scmpuff-test
$ cd scmpuff-test
$ git init
$ git branch -m main
$ nix flake new . -t templates#utils-generic
$ gs

If I can give any more environment issue to help diagnose the source of the new file status, let me know.

Hi @jackbashford, thanks for your patience. scmpuff v0.6.0 is now out which contains a debug command that should be able to help us reproduce and solve this issue. If you upgrade to this version and then run scmpuff debug dump --archive in a repository that has this state, it will generate an archive containing debug files I can use to make a test case with an exact reproduction of the repo state.

Happens for me when I have a git repo with untracked files, and then I initialise a Jujutsu repo on top. This changes the untracked file to a new file not staged for commit.

To repro:

❯ git clone https://github.com/jkoppel/jj-workshop

An easy way to get the A flag to show up, that doesn't rely on any other tools/binaries (like nix or jj) is shown in https://github.com/mroth/scmpuff/issues/53

It's basically this:

mkdir scmpuff_test
cd scmpuff_test
git init .
touch file_to_be_added.txt
git add . -N

Now, when running git status --porcelain I see this:

 A file_to_be_added.txt

Following up with a git add file_to_be_added.txt the porcelain output changes to

A  file_to_be_added.txt

So, difficult to see, but the first output had <space>A, the second one (after git add) doesn't have the initial <space>.
