# Homebrew/homebrew-core is extremely expensive to perform shallow clones on
# so, on GitHub's request, don't allow it.

homebrew-core is a shallow clone. To \`brew update\` first run:
git -C "$HOMEBREW_LIBRARY/Taps/homebrew/homebrew-core" fetch --unshallow
This restriction has been made on GitHub's request because updating shallow
clones is an extremely expensive operation due to the tree layout and traffic of
Homebrew/homebrew-core. We don't do this for you automatically to avoid
repeatedly performing an expensive unshallow operation in CI systems (which
should instead be fixed to not use shallow clones). Sorry for the inconvenience!
