* docs: state that MinIO-encrypted objects are not readable by RustFS
Operators evaluating a MinIO migration had no warning that objects MinIO
wrote with SSE-S3, SSE-KMS, or SSE-C cannot be read back. The container
formats interoperate, so the limitation is easy to discover only after
the data has moved.
Document the limitation where a migration decision is actually made:
- minio-file-format-compat.md gains Part C, covering which object classes
transfer, the three seams that block each SSE mode with file:line
evidence, the reverse direction, and the current workarounds. It also
records that the `rio-v2` MinIO sealed-key parser does not close the
gap: the feature is absent from released artifacts, and the managed-SSE
detection gate is not feature-gated and returns before the parser runs.
- kms-backend-security.md gains an operator-facing warning next to the
backend comparison table, since configuring the static backend with
MinIO's key material looks like it should work and does not.
- s3-compatibility-matrix.md scopes its SSE row to RustFS's own
round-trip.
The read path treats an undetected MinIO-encrypted object as unencrypted
rather than failing, so all three notes tell operators to verify migrated
objects by content instead of by status code.
Refs rustfs/backlog#1638.
* docs: correct the failure mode for MinIO-encrypted objects
The read path does fail closed; the earlier text claimed ciphertext was
served as plaintext. MinIO's internal headers mark the object encrypted,
so the reader refuses when no material resolves. What is actually wrong
is the diagnosis: the refusal surfaces as a 500 InternalError.
* ci(ilm): move first batch of 5 s3-tests lifecycle expiration cases into a gated behavior lane (backlog#1148 ilm-10)
The 20 lifecycle cases in excluded_tests.txt were labeled "vendor-specific"
but the real blocker was the absence of a Ceph lc_debug_interval equivalent.
RUSTFS_ILM_DEBUG_DAY_SECS (ilm-5) now provides that, so Days>=1 expiration
behavior is testable in seconds.
These cases assert that objects/versions/uploads are actually removed by the
background scanner and the stale-multipart cleanup loop. They cannot join the
default single-server s3-implemented-tests gate: it disables the scanner, and a
global RUSTFS_ILM_DEBUG_DAY_SECS also shrinks the x-amz-expiration header that
the already-passing test_lifecycle_expiration_header_* cases assert on. So this
adds an isolated lane instead of putting them in implemented_tests.txt.
First batch (5), each verified against the pinned upstream source and the
RustFS evaluator/scanner/stale-multipart execution paths:
- test_lifecycle_expiration (prefix Days=1/Days=5, scanner delete)
- test_lifecyclev2_expiration (same via ListObjectsV2)
- test_lifecycle_noncur_expiration (NoncurrentVersionExpiration)
- test_lifecycle_deletemarker_expiration (ExpiredObjectDeleteMarker cascade)
- test_lifecycle_multipart_expiration (AbortIncompleteMultipartUpload)
Dropped from the batch, kept excluded with reason:
- test_lifecycle_expiration_days0: RustFS accepts Expiration{Days:0} (returns
200; only Days<0 is rejected in crates/lifecycle/src/core.rs validate()),
while AWS/this test expect InvalidArgument. Real validation gap.
Changes:
- scripts/s3-tests/lifecycle_behavior_tests.txt: new exact-node-id run set.
- scripts/s3-tests/run.sh: honor an IMPLEMENTED_TESTS_FILE override so a lane
can point at an alternate whitelist.
- .github/workflows/ci.yml: new s3-lifecycle-behavior-tests PR-gate job that
starts rustfs with RUSTFS_ILM_DEBUG_DAY_SECS=10, scanner enabled (cycle 2s,
no start delay) and a 2s stale-multipart cleanup interval, running the new
list serially.
- scripts/s3-tests/report_compat.py: recognize the behavior list so the weekly
scope=all sweep (plain server) does not misclassify expected failures.
- scripts/s3-tests/excluded_tests.txt: remove the 5 enabled cases; re-annotate
the remaining 15 lifecycle exclusions with real reasons + batch-2 plan.
- docs/architecture/s3-compatibility-matrix.md: sync counts (implemented 451,
excluded 274, behavior 5) and document the lane.
