Closes#32396.
StampModTimes now normalizes the supplied time to UTC and truncates to
whole seconds before stamping. Without this, an SDK caller passing a
local-timezone or sub-second time.Time would produce a Chart.lock
generated: field with a timezone offset or fractional seconds, making
the lock file content non-reproducible across machines even when the
same SOURCE_DATE_EPOCH value is used — defeating the purpose of the
feature.
Also add:
- testdata/charts/chart-with-lock fixture: a minimal chart with a
Chart.lock whose generated: timestamp predates SOURCE_DATE_EPOCH.
- TestRunWithSourceDateEpochStampsLockGenerated: packages the fixture
with SourceDateEpoch set to a non-UTC, sub-second time.Time and
asserts that the resulting archive's Chart.lock entry has both the
correct tar modtime and the correct (normalized) generated: value in
the marshaled YAML.
