[bug] V2 Builds Crash on shallow checkout

[jamestalmage]

We use moon both to run our CI pipeline (github actions), and deploy our build (Cloudflare Pages / Workers Build).

Cloudflare does a shallow checkout. V1 would work, but issue a warning that it couldn't use git to determine affected files. V2 just fails to run:

15:05:48.997 | [ WARN 2026-02-21 20:05:48.995] moon_app::queries::changed_files  Detected a shallow checkout, unable to run Git commands to determine changed files.

I'm pretty sure none of this logic has changed in v2. Can you verify the same git commands are running in v1 and v2?

[milesj]

v1 = https://github.com/moonrepo/moon/blob/release-1.0/crates/app/src/commands/ci.rs#L143
v2 = https://github.com/moonrepo/moon/blob/master/crates/app/src/commands/exec.rs#L363

What command are you running? This is probably a side-effect of merging all the exec commands.

I was running moon run web:build... I figured out I could run git fetch --unshallow && moon... and that fixed it.

I'm pretty sure that's checking out more than it needs too, but other commands I tried didn't work. Might be worth adding the --unshallow command (or whatever ends up being most efficient) to the docs somewhere

Ok try v2.0.3.

Fixed!
