Build archive includes files ignored by a .gitignore inside a dot-directory #4536

Build/Submit details page URL

No response

Summary

eas-cli skips .gitignore files inside dot-directories when it copies the project for the build archive, so files git ignores there get uploaded anyway. Ignore.initIgnoreAsync in packages/eas-cli/src/vcs/local.ts finds them with fg('**/.gitignore'), and fast-glob's ** doesn't descend into dot-directories unless you pass dot: true.

Managed or bare?

Managed (CNG)

Environment

eas-cli 22.0.0, Node 24.11.0, macOS 15.7. The same glob call is in 24.10.0. I skipped expo-env-info because the bug is in eas-cli's own copy step and doesn't depend on the SDK.

Error output

None. The archive is just bigger than it should be.

Reproducible demo or steps to reproduce from a blank project

mkdir repro && cd repro && git init
mkdir .cache
echo 'big-file' > .cache/.gitignore
echo x > .cache/big-file
git check-ignore -v .cache/big-file
# .cache/.gitignore:1:big-file	.cache/big-file

npm i --no-save eas-cli@24.10.0
node -e "
const { makeShallowCopyAsync } = require('eas-cli/build/vcs/local');
makeShallowCopyAsync(process.cwd(), '../out').then(() => console.log('copied'));"
ls -A ../out/.cache
# .gitignore  big-file

big-file should not be in ../out.
