"[git-rev-sync] no git repository found" when working with git --work-tree

[janwerkhoven]

A common pattern in production environments is to put a bare git repository (see repo/) outside the working directories (see releases/) so you can deploy with minimal disruption of the live release:

current -> symlink to releases/3
repo/
releases/1/
releases/2/
releases/3/
releases/3/package.json
releases/3/node_modules
releases/3/config/environment.js

Which deploys with a command like:

git --work-tree=/path/to/releases/3/ --git-dir=/path/to/repo/ checkout $branch -f

Running git.short() in the environment.js I keep getting this error:

[git-rev-sync] no git repository found

I tried:

git.short('/absolute/path/to/repo/');
git.short('../repo/');
git.short('../../repo/');
...

Whatever I try, can't seem to grab the git repository.

Any ideas?

yeah this is a known issue; open to PRs with a reasonable approach on the best way to handle this

[janwerkhoven]

Because work tree directories do not have a .git directory I don't believe we can make git-rev-sync discover the git directory.

Possible solutions:

1. Allow the git directory to be passed as argument git.short('/path/to/repo/')
2. Manually add a .git symlink to /path/to/repo/ the root of every work tree?

https://github.com/NiceLabs/git-rev

import { Git }  from "@nice-labs/git-rev";
import * as path from "path";

const git = new Git(path.relative(process.cwd(), "../../repo"))

git.commitHash()

// equivalent form: git rev-parse HEAD
// working directory: path.relative(process.cwd(), "../../repo")

Can come and use my brand new implementation.
