# Regression: detect_platform / get_repo_info must FAIL LOUDLY outside a git repo,
|
|
# not kill the caller silently.
|
|
#
|
|
# Both functions already contained the right error path:
|
|
# if [[ -z "$remote_url" ]]; then echo "error: not a git repository..." >&2; return 1; fi
|
|
# but under `set -e` -- which every wrapper in this directory uses -- the preceding
|
|
# assignment `remote_url=$(git remote get-url origin 2>/dev/null)` returns git's 128
|
|
# outside a repo and terminates the CALLER first. The message was unreachable.
|
|
#
|
|
# Observed cost: pr-review.sh invoked from a non-repo cwd exits 128 with NO stdout and
|
|
# NO stderr, even when -r/--repo and -H/--host are supplied -- the flags documented as
|
|
# "skips git-remote inference". Two reviewer seats hit this and correctly reported
|
|
# `blocked` with no diagnostic to report.
|
|
#
|
|
# The control that matters is the LOUD one: asserting "rc != 0" passes on the broken
|
|
# build too, because 128 is also non-zero. The test must assert the MESSAGE.
