ci: keep leading whitespace in workload profile git output - #13883
Conversation
git_text() stripped both ends of git output, so the first line of `git submodule status --recursive` lost the space that marks a clean gitlink. source_identity() then read the SHA as the status marker and refused every checkout with a materialized submodule as malformed, which blocks cmux.macos.dev-check and compile-admission on real checkouts.

Isolate global Git configuration for the checkout test.
GIT_CONFIG_NOSYSTEM disables system configuration, but the helper still reads the caller's global configuration. If commit.gpgSign=true and no signing key is available, a fixture commit fails before the regression assertion. Isolate HOME and XDG_CONFIG_HOME for the entire test, including source_identity(). Git documents both the global configuration lookup and commit-signing setting. (git-scm.com)

scripts/ci/cmux_workload_profile.pyrefuses every real checkout that has a materialized submodule, withcheckout submodule status is malformed. This came up during the first mini canary for #13491: Glaedaaccept-localrancmux.macos.dev-check@1on a clean checkout of34ebc29and the profile runner stopped after 0.4 s, before any build.Cause:
git_text()returnedstdout.strip(). For a clean gitlink,git submodule status --recursivestarts each line with a space. The strip removed that space from the first line only, sosource_identity()read the first SHA character as the status marker and found no space at column 41. The unit tests fed pre-shaped lines to a mockedgit_text, so they never saw the strip.Fix:
git_text()now removes only trailing newlines. Leading whitespace is data forsubmodule statusand for porcelain status. The other callers (rev-parsevalues, emptiness checks) are unaffected.Commit 1 adds
test_source_identity_accepts_real_checkout_with_clean_submodule, which builds a real temporary superproject with a clean submodule and runssource_identity()against it. It fails on the old code with the same error. Commit 2 is the fix.Local run: the new test passes.
test_forced_cleanup_receipt_reports_unsettled_process_group(needs Linux) andtest_runtime_product_identity_covers_neighboring_product_bytes(/tmpsymlink on macOS) also fail on unmodifiedmainon macOS, so this change does not cause them.This does not fix two separate Glaeda bootstrap defects that block the same canary. They are reported on the issue.

git_text()now removes only trailing newlines sogit statusoutput retains the submodule status marker.git_text()callers are now agnostic to the output format instead of silently relying on whitespace changes.source_identity()on a real temporary superproject with a clean submodule.Written for commit 97844b5. Summary will update on new commits.
