PutBucketLifecycleConfiguration used to install /buckets/<bucket>/<prefix>
day-TTL entries in filer.conf so the volume server's RocksDB compaction
filter would expire matching writes. With 9377 the s3api server now stamps
volume TTL per-write via LifecycleTTLResolver off the stored XML, which
covers the same prefix-only Expiration.Days subset and additionally
handles size filters and AWS overlapping-rule precedence. Maintaining
both paths means a rule change has to mutate two stores in lockstep, and
the filer.conf path can't represent everything the resolver does.
Drop the add path. Keep a one-way cleanup loop so an upgrade still wipes
day-TTL entries written by older builds — otherwise a stale entry would
silently double-stamp writes (volume server expires under the old rule)
or contradict the new XML after a rule change.
Also removes resolveLifecycleDefaultsFromFilerConf (no longer needed) and
the versioning-fast-path guard (the resolver itself returns nil for
versioned/object-lock buckets, covered by
TestNewLifecycleTTLResolver_NilOnVersionedBucket). Tests covering the
deleted helpers are deleted with them; the GET fallback that synthesizes
lifecycle rules from existing filer.conf TTLs is unchanged so users who
historically configured TTL via filer.conf directly still see a rule.
* s3api: skip TTL fast-path for versioned buckets (#8757)
PutBucketLifecycleConfiguration was translating Expiration.Days into
filer.conf TTL entries for all buckets. For versioned buckets this is
wrong:
1. TTL volumes expire as a unit, destroying all data — including
noncurrent versions that should be preserved.
2. Filer-backend TTL (RocksDB compaction filter, Redis key expiry)
removes entries without triggering chunk deletion, leaving orphaned
volume data with 0 deleted bytes.
3. On AWS S3, Expiration.Days on a versioned bucket creates a delete
marker — it does not hard-delete data. TTL has no such nuance.
Fix: skip the TTL fast-path when the bucket has versioning enabled or
suspended. All lifecycle rules are evaluated at scan time by the
lifecycle worker instead.
Also fix the lifecycle worker to evaluate Expiration rules against the
latest version in .versions/ directories, which was previously skipped
entirely — only NoncurrentVersionExpiration was handled.
* lifecycle worker: handle SeaweedList error in versions dir cleanup
Do not assume the directory is empty when the list call fails — log
the error and skip the directory to avoid incorrect deletion.
* address review feedback
- Fetch version file for tag-based rules instead of reading tags from
the .versions directory entry where they are not cached.
- Handle getBucketVersioningStatus error by failing closed (treat as
versioned) to avoid creating TTL entries on transient failures.
- Capture and assert deleteExpiredObjects return values in test.
- Improve test documentation.
