* test(replication): pin missing LWW timestamp header transport
Red-light tests for the replication timestamp three-header contract:
- put_object_headers_carry_replication_timestamp_headers pins that
PutObjectOptions::header() must emit the
x-{rustfs,minio}-source-replication-{tagging,retention,legalhold}-timestamp
headers when the internal timestamps are set (currently missing).
- test_put_opts_from_headers_gates_replication_timestamp_persistence_on_authorization
and test_complete_multipart_opts_persist_replication_timestamps_when_authorized
pin that an authorized replication PUT / multipart complete must persist
the inbound timestamps into the internal metadata keys while unauthorized
requests must not (currently never persisted).
- fake_s3_target journals the three timestamp headers per request
(ReplicationTimestampHeaders on RequestRecord) so sender-side e2e
assertions can observe what a real target receives; self-test included.
* fix(replication): transport and persist LWW timestamps for tag, retention, and legal hold
Active-active conflict resolution for concurrent tag/retention/legal-hold
edits needs the source's per-category modification times on both sides of
the wire; the three AdvancedPutOptions timestamp fields were dead and the
headers were neither sent nor parsed.
- Emit x-{rustfs,minio}-source-replication-{tagging,retention,legalhold}-
timestamp from PutObjectOptions::header(); names and RFC3339 values
interoperate with MinIO (minio-go constants.go, object-api-options.go),
pinned by a header_compat wire-name test.
- Default the three AdvancedPutOptions timestamps to UNIX_EPOCH and skip
epoch values in header(), so "never modified" is not sent as a
modification made now.
- Parse the headers only on authorized replication PUTs and multipart
completes, expose them as Option<OffsetDateTime> on ObjectOptions, and
persist them into the dual-prefix internal metadata keys so the
outbound pass (replication_target_boundary) reads the source's
timestamps instead of the mod_time fallback.
- Record the local tagging timestamp in the PutObjectTagging and
DeleteObjectTagging eval metadata, mirroring the object-lock handlers;
without it the sender only ever had the mod_time fallback to offer.
Receiver-side LWW comparison (keep newer stored category metadata over a
stale inbound copy) is left as a TODO at the parse site.
* fix(replication): load the stored tagging timestamp independently of remaining tags
Review: DeleteObjectTagging persists the tagging-timestamp internal key
but leaves the object tagless, and the outbound mapper only loaded the
key inside the user_tags-nonempty branch — the deletion's LWW timestamp
stayed at the epoch and the header was omitted, so the deletion could
never win conflict resolution on the replica. The stored key is now
loaded unconditionally; the mod_time fallback still applies only while
tags exist (MinIO parity), and a tagless object without the key keeps
the epoch default (no header). Deletion-path regression test added.
* fix(storage): reserve replication transport names at metadata ingest
Second review round: a client PUT of
x-amz-meta-x-rustfs-source-replication-tagging-timestamp materialized
the bare transport key as stored user metadata. The outbound
replication header builder forwards user metadata verbatim on a
server-authorized request, so the receiver would persist the
attacker-chosen value as trusted internal LWW state — and for a
tagless object nothing later overwrites it.
The ingest namespacing guard now reserves the whole
x-rustfs-source- / x-minio-source- families (the new timestamps and
their siblings: source-mtime/-etag/-version-id/-replication-request),
folding forged keys back under x-amz-meta-. Forged-ingress regression
covers both prefixes and a sibling.
* fix(replication): harden timestamp replay
* fix(app): route retention helper through facade

Programmable fake S3 target
This module is the shared failure-injection boundary for replication end-to-end tests. It runs an in-process, path-style S3 endpoint backed by s3s; no production crate depends on it.
FakeS3Target::start() creates the listener. Add target buckets with create_bucket, point a RustFS remote target at address(), use FAKE_ACCESS_KEY / FAKE_SECRET_KEY, then enqueue per-operation faults with inject. Faults for one operation are consumed in FIFO order and do not consume faults queued for another operation. A fault is consumed only after s3s verifies the full request signature, so anonymous, other-access-key, and bad-signature traffic cannot disturb a script.
Supported data operations are HeadBucket, GetBucketVersioning, PUT/GET/HEAD/DELETE Object, and create/upload/complete/abort multipart upload. create_bucket models general-purpose buckets in S3's shared global namespace; account-regional namespace buckets and their -an names are intentionally out of scope. Buckets are versioned: PUT creates a version, DELETE without versionId creates a delete marker, and DELETE with versionId removes exactly that version. Internal source version IDs must be UUIDs and are stored canonically. Source mtime is honored only for source-replication PUT/DELETE requests; absent or invalid values use receipt time, matching RustFS, while multipart completion always uses receipt time. Replicated versions are ordered newest-first by source mtime so late older versions and delete markers do not become current. Equal mtimes prefer objects over delete markers, then canonical UUID order; RustFS's internal FileMeta signature tie-break is intentionally out of scope because it is not part of the target S3 protocol. Multipart part numbers follow S3's 1..=10000 range, and every completed part except the final part must be at least 5 MiB.
Fault actions cover HTTP 401/403/503 responses, pre-dispatch delay, connection abort when a logical request-body threshold is reached, streaming slow drain, and a deliberately wrong response ETag (including multipart-complete XML). requests() returns the ordered, credential-free request journal for assertions.
The listener is loopback-only. It admits at most 64 active connections and two concurrently buffered request bodies; authenticated multipart-complete XML collection and assembly take both body permits. Keep-alive is disabled, request-header reads are bounded to 30 seconds, a parsed request is bounded to 65 seconds, and the complete connection lifetime is bounded to 100 seconds. It retains at most 256 buckets, 4,096 journal entries, 4,096 scripted faults, 4,096 object versions, 256 multipart uploads, and 10,000 multipart parts. Retained identifiers are capped at 1 KiB, user metadata at 2 KiB, and content type at 1 KiB. A PUT or uploaded part is capped at 64 MiB; a completed multipart object and all stored object/part data are capped at 128 MiB. Body drain, body-permit waits, delay, and slow-drain execution are bounded to 30 seconds; each slow-drain slice delay must be below that bound.
