An operator changes the lifecycle rule between two shell-driven
sweeps. The second sweep must respect the NEW rule, not a cached
copy of the old one. Each runLifecycleShard invocation spawns a
fresh weed shell subprocess, so cached engine state from a previous
sweep doesn't persist — but a regression that caches rules across
PutBucketLifecycleConfiguration calls within the S3 server itself
would still surface here.
Sweep 1: rule prefix="first/", PUT + backdate firstKey, run worker
→ firstKey expires.
Update rule to prefix="second/", PUT + backdate secondKey AND a
new key under the OLD prefix ("first/post-update.txt"). Sweep 2
must expire only the second-prefix object; the post-update old-
prefix one must survive — config replacement, not merge.
S3 Lifecycle Integration Tests
End-to-end test of the event-driven S3 lifecycle worker, exercised through
the s3.lifecycle.run-shard shell command.
Why backdate mtimes?
The S3 API rejects Expiration.Days < 1, so a literal "wait one day"
integration test isn't workable. Each test sets up a 1-day expiration rule,
puts the target object, then rewrites its filer entry's Mtime to ~30 days
ago via filer_pb.UpdateEntry. From the engine's perspective the object is
past its expiration window the moment the shell command starts.
Running
# build the binary, start a local mini cluster, run tests, stop it
make test-with-server
# or, if a cluster is already running on the default ports
make test
The test runs the shell command once with -shards 0-15 (one filer
subscription covering all 16 shards) rather than computing the target
object's shard up front. This keeps the test independent of the
ShardID(bucket, key) hash function — only that some shard reaches the
deletion within the polling window.
