Chris LuandGitHub 7aaa431bb4 s3api: prune bucket-scoped IAM actions on DeleteBucket (#9054)
* s3api: prune bucket-scoped IAM actions on DeleteBucket

DeleteBucket removed the bucket directory and collection but left
behind any identity actions configured via s3.configure that were
scoped to that bucket (e.g. Read:bucket, Write:bucket/prefix),
leaving stale auth metadata that users expected to be cleaned up
along with the bucket.

After a successful delete, strip actions whose resource is exactly
the bucket or a prefix under it, save via the credential manager,
and let the existing filer metadata subscription fan the reload out
to every S3 server. Wildcarded resources and global actions are
preserved since they may cover other buckets; static identities
are left untouched.

Fixes #5310

* s3api: address review feedback on bucket IAM prune

- Apply per-identity updates via credentialManager.UpdateUser instead
  of a full LoadConfiguration/SaveConfiguration round-trip, so the
  prune no longer clobbers concurrent IAM edits made by s3.configure
  or the IAM API during a DeleteBucket.
- Use a 30s bounded background context for the post-delete cleanup so
  it survives client disconnect — the bucket is already gone by then
  and this is best-effort bookkeeping.
- Skip static identities via IsStaticIdentity, since the credential
  store never persists them and UpdateUser would return NotFound.

Chris LuandGitHub c390448906 fix(s3): preserve exact policy document in embedded IAM put/get-user-policy (#9025)
* fix(s3): preserve exact policy document in embedded IAM PutUserPolicy/GetUserPolicy (#9008)

The embedded IAM implementation (used when IAM requests go through the
S3 gateway) discarded the original policy document on PutUserPolicy,
storing only the lossy ident.Actions representation. GetUserPolicy then
reconstructed the document from these coarse-grained actions, producing
wildcard-expanded actions (s3:GetObject → s3:Get*), duplicates, and
collapsed resources (array → single string).

PR #9009 fixed this in the standalone IAM server (weed/iamapi/) but the
embedded IAM (weed/s3api/) — which is the code path most users hit —
had the same bugs.

Changes:

- Add InlinePolicyStore optional interface to credential store, with
  implementations for FilerEtcStore (uses existing PoliciesCollection),
  MemoryStore, and PropagatingCredentialStore.

- Embedded IAM PutUserPolicy now persists the original policy document
  via CredentialManager.PutUserInlinePolicy for lossless round-trips.

- Embedded IAM GetUserPolicy first tries the stored inline policy; only
  falls back to lossy reconstruction from ident.Actions when no stored
  document exists (e.g. policies created before this fix).

- Fix the fallback reconstruction: add action deduplication and preserve
  resource paths verbatim (no more spurious /* appending).

- Update DeleteUserPolicy/ListUserPolicies to use stored inline policies.

* fix(s3): address PR review feedback for embedded IAM inline policies

- Validate PolicyName is non-empty in PutUserPolicy and DeleteUserPolicy
- Add recomputeActions() to aggregate ident.Actions from ALL stored
  inline policies on put/delete, fixing the issue where a second
  PutUserPolicy would overwrite the first policy's enforcement
- Log errors from GetUserInlinePolicy in the GetUserPolicy fallback
  instead of silently ignoring them
- Add initialization guards to MemoryStore GetUserInlinePolicy and
  ListUserInlinePolicies for consistency with other read methods

* fix(s3): make inline policy persistence fatal and propagate recompute errors

Address second round of review feedback:

- recomputeActions() now returns ([]string, error) so callers can
  distinguish store failures from "no stored policies" and abort the
  mutation on transient errors instead of silently falling back.

- PutUserInlinePolicy and DeleteUserInlinePolicy failures are now fatal:
  the API call returns ServiceFailure instead of logging and continuing,
  keeping ident.Actions and stored policy state in sync.

Chris LuandGitHub 2b8c16160f feat(iceberg): add OAuth2 token endpoint for DuckDB compatibility (#9017)
* feat(iceberg): add OAuth2 token endpoint for DuckDB compatibility (#9015)

DuckDB's Iceberg connector uses OAuth2 client_credentials flow,
hitting POST /v1/oauth/tokens which was not implemented, returning 404.

Add the OAuth2 token endpoint that accepts S3 access key / secret key
as client_id / client_secret, validates them against IAM, and returns
a signed JWT bearer token. The Auth middleware now accepts Bearer tokens
in addition to S3 signature auth.

* fix(test): use weed shell for table bucket creation with IAM enabled

The S3 Tables REST API requires SigV4 auth when IAM is configured.
Use weed shell (which bypasses S3 auth) to create table buckets,
matching the pattern used by the Trino integration tests.

* address review feedback: access key in JWT, full identity in Bearer auth

- Include AccessKey in JWT claims so token verification uses the exact
  credential that signed the token (no ambiguity with multi-key identities)
- Return full Identity object from Bearer auth so downstream IAM/policy
  code sees an authenticated request, not anonymous
- Replace GetSecretKeyForIdentity with GetCredentialByAccessKey for
  unambiguous credential lookup
- DuckDB test now tries the full SQL script first (CREATE SECRET +
  catalog access), falling back to simple CREATE SECRET if needed
- Tighten bearer auth test assertion to only accept 200/500

Addresses review comments from coderabbitai and gemini-code-assist.

* security: use PostFormValue, bind signing key to access key, fix port conflict

- Use r.PostFormValue instead of r.FormValue to prevent credentials from
  leaking via query string into logs and caches
- Reject client_secret in URL query parameters explicitly
- Include access key in HMAC signing key derivation to prevent
  cross-credential token forgery when secrets happen to match
- Allocate dedicated webdav port in OAuth test env to avoid port
  collision with the shared TestMain cluster

Chris LuandGitHub ba90ae5c94 fix(s3): don't count ErrNotFound as filer health failure in failover (#8995)
* fix(s3): don't count ErrNotFound as filer health failure in failover

The S3 gateway's filer client failover was recording ErrNotFound
(entry doesn't exist) as a filer health failure. In multi-filer
setups where filers have separate metadata stores, normal object
lookups that return "not found" accumulated in the circuit breaker,
eventually marking healthy filers as unhealthy after just 3 lookups.

This caused the distributed lock integration test to fail with 500
InternalError: once a filer was circuit-broken, subsequent lookups
could no longer fall back, turning a would-be 412 PreconditionFailed
into an unrecoverable internal error.

Only record actual transport/server failures in the health tracker.
The failover still tries other filers for data locality, but no
longer penalizes filers for correctly reporting missing entries.

* style: inline isNotFound variable for consistency

The variable was only used once; inlining it matches the pattern
already used in the failover loop a few lines below.

Chris LuandGitHub e21d7602c3 feat(iam): implement group inline policy actions (#8992)
* feat(iam): implement group inline policy actions

Add PutGroupPolicy, GetGroupPolicy, DeleteGroupPolicy, and
ListGroupPolicies to both embedded and standalone IAM servers.

The standalone IAM stores group inline policies in a new
GroupInlinePolicies field in the Policies JSON, mirroring the
existing user inline policy pattern. DeleteGroup now also checks
for inline policies before allowing deletion.

* fix: address review feedback for group inline policies

- Embedded IAM: return NotImplemented for group inline policies
  instead of silently succeeding as no-ops (Gemini + CodeRabbit)
- Standalone IAM: recompute member actions after PutGroupPolicy
  and DeleteGroupPolicy (Gemini)
- Add parameter validation for GroupName/PolicyName/PolicyDocument
  on PutGroupPolicy, DeleteGroupPolicy, ListGroupPolicies (Gemini)
- Add UserName validation for ListUserPolicies in standalone IAM
- Call cleanupGroupInlinePolicies from DeleteGroup (Gemini)
- Migrate GroupInlinePolicies on group rename in UpdateGroup (CodeRabbit)
- Fix integration test cleanup order (CodeRabbit)

* fix: persist recomputed actions and improve error handling

- Set changed=true for PutGroupPolicy/DeleteGroupPolicy in standalone
  IAM DoActions so recomputed member actions are persisted (Gemini critical)
- Make cleanupGroupInlinePolicies accept policies parameter to avoid
  redundant I/O, return error (Gemini)
- Make migrateGroupInlinePolicies return error, handle in caller (Gemini)

* fix: include group policies in action recomputation

Extend computeAllActionsForUser to also aggregate group inline
policies and group managed policies when s3cfg is provided.
Previously, group inline policies were stored but never reflected
in member Identity.Actions. (CodeRabbit critical)

* perf: use identity index in recomputeActionsForGroupMembers for O(N+M)

* fix: skip group inline policy integration test on embedded IAM

The embedded IAM returns NotImplemented for group inline policies.
Skip TestIAMGroupInlinePolicy when running against embedded mode
to avoid CI failures in the group integration test matrix.

fix(s3): handle empty URL path in forwarded prefix signature verification (#8966)

When S3 is behind a reverse proxy with a forwarded prefix (e.g. /s3),
requests with an empty URL path (like ListBuckets) would incorrectly
get a trailing slash appended (e.g. /s3/), causing signature
verification to fail because the client signs /s3 without the slash.

Chris LuandGitHub 79a48256f5 fix(s3): populate s3:prefix from query param for ListObjects policy conditions (#8971)
* fix(s3): populate s3:prefix from query param for ListObjects policy conditions (#8969)

ListObjectsV2/V1 requests with prefix-restricted STS session policies
were denied because:
1. s3:prefix was derived from objectKey, which the auth middleware set to
   the prefix value, but the resource ARN then included the prefix
   (e.g. arn:aws:s3:::bucket/prefix) instead of staying at bucket level
   (arn:aws:s3:::bucket) as AWS requires for ListBucket.
2. When objectKey was empty (no middleware propagation), s3:prefix was
   never populated from the query parameter at all.

Now AuthorizeAction extracts the prefix query parameter directly, sets it
as s3:prefix in the request context, and uses a bucket-level resource ARN
when the objectKey matches the propagated prefix.

* fix(s3): use AWS-style wildcard matching for StringLike policy conditions

filepath.Match treats * as not matching /, which breaks IAM StringLike
conditions on paths (e.g. arn:aws:s3:::bucket/* won't match nested keys).
Replace with a case-sensitive variant of AwsWildcardMatch that correctly
treats * as matching any character including /.

* refactor(s3): replace regex wildcard matching with string-based matcher

Use the existing wildcard.MatchesWildcard utility instead of compiling
and caching regexes for IAM wildcard matching. Removes the regexCache,
its mutex, and the sync import.

* refactor(s3): inline and remove AwsWildcardMatch wrapper functions

Replace all call sites with direct wildcard.MatchesWildcard calls.

* fix(s3): scope s3:prefix condition key to list operations only

The s3:prefix logic was running for all actions, so a GetObject on
"foo/bar" would wrongly populate s3:prefix. Restrict it to action "List"
and always reset resourceObjectKey to "" so the resource ARN stays at
bucket level. Also set s3:prefix to "" when no prefix is provided, so
policies with StringEquals {"s3:prefix": ""} evaluate correctly.

Chris LuandGitHub 761ec7da00 fix(iceberg): use dot separator for namespace paths instead of unit separator (#8960)
* fix(iceberg): use dot separator for namespace paths instead of unit separator

The Iceberg REST Catalog handler was using \x1F (unit separator) to join
multi-level namespaces when constructing S3 location and filer paths. The
S3 Tables storage layer uses "." (dot) as the namespace separator, causing
tables created via the Iceberg REST API to point to different paths than
where S3 Tables actually stores them.

Fixes #8959

* fix(iceberg): use dot separator in log messages for readable namespace output

* fix(iceberg): use path.Join for S3 location path segments

Use path.Join to construct the namespace/table path segments in fallback
S3 locations for robustness and consistency with handleCreateTable.

* test(iceberg): add multi-level namespace integration tests for Spark and Trino

Add regression tests for #8959 that create a two-level namespace (e.g.
"analytics.daily"), create a table under it, insert data, and query it
back. This exercises the dot-separated namespace path construction and
verifies that Spark/Trino can actually read the data at the S3 location
returned by the Iceberg REST API.

* fix(test): enable nested namespace in Trino Iceberg catalog config

Trino requires `iceberg.rest-catalog.nested-namespace-enabled=true` to
support multi-level namespaces. Without this, CREATE SCHEMA with a
dotted name fails with "Nested namespace is not enabled for this catalog".

* fix(test): parse Trino COUNT(*) output as integer instead of substring match

Avoids false matches from strings.Contains(output, "3") by parsing the
actual numeric result with strconv.Atoi and asserting equality.

* fix(test): use separate Trino config for nested namespace test

The nested-namespace-enabled=true setting in Trino changes how SHOW
SCHEMAS works, causing "Internal error" for all tests sharing that
catalog config. Move the flag to a dedicated config used only by
TestTrinoMultiLevelNamespace.

* fix(iceberg): support parent query parameter in ListNamespaces for nested namespaces

Add handling for the Iceberg REST spec's `parent` query parameter in
handleListNamespaces. When Trino has nested-namespace-enabled=true, it
sends `GET /v1/namespaces?parent=<ns>` to list child namespaces. The
parent value is decoded from the Iceberg unit separator format and
converted to a dot-separated prefix for the S3 Tables layer.

Also simplify TestTrinoMultiLevelNamespace to focus on namespace
operations (create, list, show tables) rather than data operations,
since Trino's REST catalog has a non-empty location check that conflicts
with server-side metadata creation.

* fix(test): expand Trino multi-level namespace test and merge config helpers

- Expand TestTrinoMultiLevelNamespace to create a table with explicit
  location, insert rows, query them back, and verify the S3 file path
  contains the dot-separated namespace (not \x1F). This ensures the
  original #8959 bug would be caught by the Trino integration test.
- Merge writeTrinoConfig and writeTrinoNestedNamespaceConfig into a
  single parameterized function using functional options.

Chris LuandGitHub 733517df30 fix(s3): s3:PutObject bucket policy now implicitly allows multipart uploads (#8968)
* fix(s3): s3:PutObject bucket policy now implicitly allows multipart uploads

The PolicyEngine.evaluateStatement() method used raw regex matching for
actions, bypassing the multipart-inherits-PutObject logic that only
existed in the unused CompiledStatement.MatchesAction() code path.

When a bucket policy granted only s3:PutObject, multipart upload
operations (CreateMultipartUpload, UploadPart, CompleteMultipartUpload,
etc.) were denied, forcing users to explicitly list every multipart
action.

Fixes https://github.com/seaweedfs/seaweedfs/discussions/8751

* fix(s3): add s3:UploadPartCopy to multipartActionSet and improve test coverage

Add missing S3_ACTION_UPLOAD_PART_COPY constant and include it in
multipartActionSet so UploadPartCopy is implicitly allowed by s3:PutObject.

Also add a bucket-ARN sub-test for ListBucketMultipartUploads to verify
that an object-only resource pattern does not match bucket-level requests.

Chris LuandGitHub d1823d3784 fix(s3): include static identities in listing operations (#8903)
* fix(s3): include static identities in listing operations

Static identities loaded from -s3.config file were only stored in the
S3 API server's in-memory state. Listing operations (s3.configure shell
command, aws iam list-users) queried the credential manager which only
returned dynamic identities from the backend store.

Register static identities with the credential manager after loading
so they are included in LoadConfiguration and ListUsers results, and
filtered out before SaveConfiguration to avoid persisting them to the
dynamic store.

Fixes https://github.com/seaweedfs/seaweedfs/discussions/8896

* fix: avoid mutating caller's config and defensive copies

- SaveConfiguration: use shallow struct copy instead of mutating the
  caller's config.Identities field
- SetStaticIdentities: skip nil entries to avoid panics
- GetStaticIdentities: defensively copy PolicyNames slice to avoid
  aliasing the original

* fix: filter nil static identities and sync on config reload

- SetStaticIdentities: filter nil entries from the stored slice (not
  just from staticNames) to prevent panics in LoadConfiguration/ListUsers
- Extract updateCredentialManagerStaticIdentities helper and call it
  from both startup and the grace.OnReload handler so the credential
  manager's static snapshot stays current after config file reloads

* fix: add mutex for static identity fields and fix ListUsers for store callers

- Add sync.RWMutex to protect staticIdentities/staticNames against
  concurrent reads during config reload
- Revert CredentialManager.ListUsers to return only store users, since
  internal callers (e.g. DeletePolicy) look up each user in the store
  and fail on non-existent static entries
- Merge static usernames in the filer gRPC ListUsers handler instead,
  via the new GetStaticUsernames method
- Fix CI: TestIAMPolicyManagement/managed_policy_crud_lifecycle was
  failing because DeletePolicy iterated static users that don't exist
  in the store

* fix: show static identities in admin UI and weed shell

The admin UI and weed shell s3.configure command query the filer's
credential manager via gRPC, which is a separate instance from the S3
server's credential manager. Static identities were only registered
on the S3 server's credential manager, so they never appeared in the
filer's responses.

- Add CredentialManager.LoadS3ConfigFile to parse a static S3 config
  file and register its identities
- Add FilerOptions.s3ConfigFile so the filer can load the same static
  config that the S3 server uses
- Wire s3ConfigFile through in weed mini and weed server modes
- Merge static usernames in filer gRPC ListUsers handler
- Add CredentialManager.GetStaticUsernames helper
- Add sync.RWMutex to protect concurrent access to static identity
  fields
- Avoid importing weed/filer from weed/credential (which pulled in
  filer store init() registrations and broke test isolation)
- Add docker/compose/s3_static_users_example.json

* fix(admin): make static users read-only in admin UI

Static users loaded from the -s3.config file should not be editable
or deletable through the admin UI since they are managed via the
config file.

- Add IsStatic field to ObjectStoreUser, set from credential manager
- Hide edit, delete, and access key buttons for static users in the
  users table template
- Show a "static" badge next to static user names
- Return 403 Forbidden from UpdateUser and DeleteUser API handlers
  when the target user is a static identity

* fix(admin): show details for static users

GetObjectStoreUserDetails called credentialManager.GetUser which only
queries the dynamic store. For static users this returned
ErrUserNotFound. Fall back to GetStaticIdentity when the store lookup
fails.

* fix(admin): load static S3 identities in admin server

The admin server has its own credential manager (gRPC store) which is
a separate instance from the S3 server's and filer's. It had no static
identity data, so IsStaticIdentity returned false (edit/delete buttons
shown) and GetStaticIdentity returned nil (details page failed).

Pass the -s3.config file path through to the admin server and call
LoadS3ConfigFile on its credential manager, matching the approach
used for the filer.

* fix: use protobuf is_static field instead of passing config file path

The previous approach passed -s3.config file path to every component
(filer, admin). This is wrong because the admin server should not need
to know about S3 config files.

Instead, add an is_static field to the Identity protobuf message.
The field is set when static identities are serialized (in
GetStaticIdentities and LoadS3ConfigFile). Any gRPC client that loads
configuration via GetConfiguration automatically sees which identities
are static, without needing the config file.

- Add is_static field (tag 8) to iam_pb.Identity proto message
- Set IsStatic=true in GetStaticIdentities and LoadS3ConfigFile
- Admin GetObjectStoreUsers reads identity.IsStatic from proto
- Admin IsStaticUser helper loads config via gRPC to check the flag
- Filer GetUser gRPC handler falls back to GetStaticIdentity
- Remove s3ConfigFile from AdminOptions and NewAdminServer signature

Chris LuandGitHub 0798b274dd feat(s3): add concurrent chunk prefetch for large file downloads (#8917)
* feat(s3): add concurrent chunk prefetch for large file downloads

Add a pipe-based prefetch pipeline that overlaps chunk fetching with
response writing during S3 GetObject, SSE downloads, and filer proxy.

While chunk N streams to the HTTP response, fetch goroutines for the
next K chunks establish HTTP connections to volume servers ahead of
time, eliminating the RTT gap between sequential chunk fetches.

Uses io.Pipe for minimal memory overhead (~1MB per download regardless
of chunk size, vs buffering entire chunks). Also increases the
streaming read buffer from 64KB to 256KB to reduce syscall overhead.

Benchmark results (64KB chunks, prefetch=4):
- 0ms latency:  1058 → 2362 MB/s (2.2× faster)
- 5ms latency:  11.0 → 41.7 MB/s (3.8× faster)
- 10ms latency: 5.9  → 23.3 MB/s (4.0× faster)
- 20ms latency: 3.1  → 12.1 MB/s (3.9× faster)

* fix: address review feedback for prefetch pipeline

- Fix data race: use *chunkPipeResult (pointer) on channel to avoid
  copying struct while fetch goroutines write to it. Confirmed clean
  with -race detector.
- Remove concurrent map write: retryWithCacheInvalidation no longer
  updates fileId2Url map. Producer only reads it; consumer never writes.
- Use mem.Allocate/mem.Free for copy buffer to reduce GC pressure.
- Add local cancellable context so consumer errors (client disconnect)
  immediately stop the producer and all in-flight fetch goroutines.

* fix(test): remove dead code and add Range header support in test server

- Remove unused allData variable in makeChunksAndServer
- Add Range header handling to createTestServer for partial chunk
  read coverage (206 Partial Content, 416 Range Not Satisfiable)

* fix: correct retry condition and goroutine leak in prefetch pipeline

- Fix retry condition: use result.fetchErr/result.written instead of
  copied to decide cache-invalidation retry. The old condition wrongly
  triggered retry when the fetch succeeded but the response writer
  failed on the first write (copied==0 despite fetcher having data).
  Now matches the sequential path (stream.go:197) which checks whether
  the fetcher itself wrote zero bytes.

- Fix goroutine leak: when the producer's send to the results channel
  is interrupted by context cancellation, the fetch goroutine was
  already launched but the result was never sent to the channel. The
  drain loop couldn't handle it. Now waits on result.done before
  returning so every fetch goroutine is properly awaited.

Chris LuandGitHub 3efe88c718 feat(s3): store and return checksum headers for additional checksum algorithms (#8914)
* feat(s3): store and return checksum headers for additional checksum algorithms

When clients upload with --checksum-algorithm (SHA256, CRC32, etc.),
SeaweedFS validated the checksum but discarded it. The checksum was
never stored in metadata or returned in PUT/HEAD/GET responses.

Now the checksum is computed alongside MD5 during upload, stored in
entry extended attributes, and returned as the appropriate
x-amz-checksum-* header in all responses.

Fixes #8911

* fix(s3): address review feedback and CI failures for checksum support

- Gate GET/HEAD checksum response headers on x-amz-checksum-mode: ENABLED
  per AWS S3 spec, fixing FlexibleChecksumError on ranged GETs and
  multipart copies
- Verify computed checksum against client-provided header value for
  non-chunked uploads, returning BadDigest on mismatch
- Add nil check for getCheckSumWriter to prevent panic
- Handle comma-separated values in X-Amz-Trailer header
- Use ordered slice instead of map for deterministic checksum header
  selection; extract shared mappings into package-level vars

* fix(s3): skip checksum header for ranged GET responses

The stored checksum covers the full object. Returning it for ranged
(partial) responses causes SDK checksum validation failures because the
SDK validates the header value against the partial content received.

Skip emitting x-amz-checksum-* headers when a Range request header is
present, fixing PyArrow large file read failures.

* fix(s3): reject unsupported checksum algorithm with 400

detectRequestedChecksumAlgorithm now returns an error code when
x-amz-sdk-checksum-algorithm or x-amz-checksum-algorithm contains
an unsupported value, instead of silently ignoring it.

* feat(s3): compute composite checksum for multipart uploads

Store the checksum algorithm during CreateMultipartUpload, then during
CompleteMultipartUpload compute a composite checksum from per-part
checksums following the AWS S3 spec: concatenate raw per-part checksums,
hash with the same algorithm, format as "base64-N" where N is part count.

The composite checksum is persisted on the final object entry and
returned in HEAD/GET responses (gated on x-amz-checksum-mode: ENABLED).

Reuses existing per-part checksum storage from putToFiler and the
getCheckSumWriter/checksumHeaders infrastructure.

* fix(s3): validate checksum algorithm in CreateMultipartUpload, error on missing part checksums

- Move detectRequestedChecksumAlgorithm call before mkdir callback so
  an unsupported algorithm returns 400 before the upload is created
- Change computeCompositeChecksum to return an error when a part is
  missing its checksum (the upload was initiated with a checksum
  algorithm, so all parts must have checksums)
- Propagate the error as ErrInvalidPart in CompleteMultipartUpload

* fix(s3): return checksum header in CompleteMultipartUpload response, validate per-part algorithm

- Add ChecksumHeaderName/ChecksumValue fields to CompleteMultipartUploadResult
  and set the x-amz-checksum-* HTTP response header in the handler, matching
  the AWS S3 CompleteMultipartUpload response spec
- Validate that each part's stored checksum algorithm matches the upload's
  expected algorithm before assembling the composite checksum; return an
  error if a part was uploaded with a different algorithm

Remove ~50,000 lines of unreachable code identified by static analysis.

Major removals:
- weed/filer/redis_lua: entire unused Redis Lua filer store implementation
- weed/wdclient/net2, resource_pool: unused connection/resource pool packages
- weed/plugin/worker/lifecycle: unused lifecycle plugin worker
- weed/s3api: unused S3 policy templates, presigned URL IAM, streaming copy,

- weed/mq/kafka: unused partition mapping, compression, schema, and protocol functions
- weed/mq/offset: unused SQL storage and migration code
- weed/worker: unused registry, task, and monitoring functions
- weed/query: unused SQL engine, parquet scanner, and type functions
- weed/shell: unused EC proportional rebalance functions
- weed/storage/erasure_coding/distribution: unused distribution analysis functions
- Individual unreachable functions removed from 150+ files across admin,
  credential, filer, iam, kms, mount, mq, operation, pb, s3api, server,
  shell, storage, topology, and util packages

* fix(s3): reset shared memory store in IAM test to prevent flaky failure

TestLoadIAMManagerFromConfig_EmptyConfigWithFallbackKey was flaky because
the MemoryStore credential backend is a singleton registered via init().
Earlier tests that create anonymous identities pollute the shared store,
causing LookupAnonymous() to unexpectedly return true.

Fix by calling Reset() on the memory store before the test runs.

* style: run gofmt on changed files

* fix: restore KMS functions used by integration tests

* fix(plugin): prevent panic on send to closed worker session channel

The Plugin.sendToWorker method could panic with "send on closed channel"
when a worker disconnected while a message was being sent. The race was
between streamSession.close() closing the outgoing channel and sendToWorker
writing to it concurrently.

Add a done channel to streamSession that is closed before the outgoing
channel, and check it in sendToWorker's select to safely detect closed
sessions without panicking.

* feat(s3): support WEED_S3_SSE_KEY env var for SSE-S3 KEK

Add support for providing the SSE-S3 Key Encryption Key (KEK) via the
WEED_S3_SSE_KEY environment variable (hex-encoded 256-bit key). This
avoids storing the master key in plaintext on the filer at /etc/s3/sse_kek.

Key source priority:
1. WEED_S3_SSE_KEY environment variable (recommended)
2. Existing filer KEK at /etc/s3/sse_kek (backward compatible)
3. Auto-generate and save to filer (deprecated for new deployments)

Existing deployments with a filer-stored KEK continue to work unchanged.
A deprecation warning is logged when auto-generating a new filer KEK.

* refactor(s3): derive KEK from any string via HKDF instead of requiring hex

Accept any secret string in WEED_S3_SSE_KEY and derive a 256-bit key
using HKDF-SHA256 instead of requiring a hex-encoded key. This is
simpler for users — no need to generate hex, just set a passphrase.

* feat(s3): add WEED_S3_SSE_KEK and WEED_S3_SSE_KEY env vars for KEK

Two env vars for providing the SSE-S3 Key Encryption Key:

- WEED_S3_SSE_KEK: hex-encoded, same format as /etc/s3/sse_kek.
  If the filer file also exists, they must match.
- WEED_S3_SSE_KEY: any string, 256-bit key derived via HKDF-SHA256.
  Refuses to start if /etc/s3/sse_kek exists (must delete first).

Only one may be set. Existing filer-stored KEKs continue to work.
Auto-generating and storing new KEKs on filer is deprecated.

* fix(s3): stop auto-generating KEK, fail only when SSE-S3 is used

Instead of auto-generating a KEK and storing it on the filer when no
key source is configured, simply leave SSE-S3 disabled. Encrypt and
decrypt operations return a clear error directing the user to set
WEED_S3_SSE_KEK or WEED_S3_SSE_KEY.

* refactor(s3): move SSE-S3 KEK config to security.toml

Move KEK configuration from standalone env vars to security.toml's new
[sse_s3] section, following the same pattern as JWT keys and TLS certs.

  [sse_s3]
  kek = ""   # hex-encoded 256-bit key (same format as /etc/s3/sse_kek)
  key = ""   # any string, HKDF-derived

Viper's WEED_ prefix auto-mapping provides env var support:
WEED_SSE_S3_KEK and WEED_SSE_S3_KEY.

All existing behavior is preserved: filer KEK fallback, mismatch
detection, and HKDF derivation.

* refactor(s3): rename SSE-S3 config keys to s3.sse.kek / s3.sse.key

Use [s3.sse] section in security.toml, matching the existing naming
convention (e.g. [s3.*]). Env vars: WEED_S3_SSE_KEK, WEED_S3_SSE_KEY.

* fix(s3): address code review findings for SSE-S3 KEK

- Don't hold mutex during filer retry loop (up to 20s of sleep).
  Lock only to write filerClient and superKey.
- Remove dead generateAndSaveSuperKeyToFiler and unused constants.
- Return error from deriveKeyFromSecret instead of ignoring it.
- Fix outdated doc comment on InitializeWithFiler.
- Use t.Setenv in tests instead of manual os.Setenv/Unsetenv.

* fix(s3): don't block startup on filer errors when KEK is configured

- When s3.sse.kek is set, a temporarily unreachable filer no longer
  prevents startup. The filer consistency check becomes best-effort
  with a warning.
- Same treatment for s3.sse.key: filer unreachable logs a warning
  instead of failing.
- Rewrite error messages to suggest migration instead of file deletion,
  avoiding the risk of orphaning encrypted data.

Finding 3 (restore auto-generation) intentionally skipped — auto-gen
was removed by design to avoid storing plaintext KEK on filer.

* fix(test): set WEED_S3_SSE_KEY in SSE integration test server startup

SSE-S3 no longer auto-generates a KEK, so integration tests must
provide one. Set WEED_S3_SSE_KEY=test-sse-s3-key in all weed mini
invocations in the test Makefile.

Chris LuandGitHub 059bee683f feat(s3): add STS GetFederationToken support (#8891)
* feat(s3): add STS GetFederationToken support

Implement the AWS STS GetFederationToken API, which allows long-term IAM
users to obtain temporary credentials scoped down by an optional inline
session policy. This is useful for server-side applications that mint
per-user temporary credentials.

Key behaviors:
- Requires SigV4 authentication from a long-term IAM user
- Rejects calls from temporary credentials (session tokens)
- Name parameter (2-64 chars) identifies the federated user
- DurationSeconds supports 900-129600 (15 min to 36 hours, default 12h)
- Optional inline session policy for permission scoping
- Caller's attached policies are embedded in the JWT token
- Returns federated user ARN: arn:aws:sts::<account>:federated-user/<Name>

No performance impact on the S3 hot path — credential vending is a
separate control-plane operation, and all policy data is embedded in
the stateless JWT token.

* fix(s3): address GetFederationToken PR review feedback

- Fix Name validation: max 32 chars (not 64) per AWS spec, add regex
  validation for [\w+=,.@-]+ character whitelist
- Refactor parseDurationSeconds into parseDurationSecondsWithBounds to
  eliminate duplicated duration parsing logic
- Add sts:GetFederationToken permission check via VerifyActionPermission
  mirroring the AssumeRole authorization pattern
- Change GetPoliciesForUser to return ([]string, error) so callers fail
  closed on policy-resolution failures instead of silently returning nil
- Move temporary-credentials rejection before SigV4 verification for
  early rejection and proper test coverage
- Update tests: verify specific error message for temp cred rejection,
  add regex validation test cases (spaces, slashes rejected)

* refactor(s3): use sts.Action* constants instead of hard-coded strings

Replace hard-coded "sts:AssumeRole" and "sts:GetFederationToken" strings
in VerifyActionPermission calls with sts.ActionAssumeRole and
sts.ActionGetFederationToken package constants.

* fix(s3): pass through sts: prefix in action resolver and merge policies

Two fixes:

1. mapBaseActionToS3Format now passes through "sts:" prefix alongside
   "s3:" and "iam:", preventing sts:GetFederationToken from being
   rewritten to s3:sts:GetFederationToken in VerifyActionPermission.
   This also fixes the existing sts:AssumeRole permission checks.

2. GetFederationToken policy embedding now merges identity.PolicyNames
   (from SigV4 identity) with policies from the IAM manager (which may
   include group-attached policies), deduplicated via a map. Previously
   the IAM manager lookup was skipped when identity.PolicyNames was
   non-empty, causing group policies to be omitted from the token.

* test(s3): add integration tests for sts: action passthrough and policy merge

Action resolver tests:
- TestMapBaseActionToS3Format_ServicePrefixPassthrough: verifies s3:, iam:,
  and sts: prefixed actions pass through unchanged while coarse actions
  (Read, Write) are mapped to S3 format
- TestResolveS3Action_STSActionsPassthrough: verifies sts:AssumeRole,
  sts:GetFederationToken, sts:GetCallerIdentity pass through ResolveS3Action
  unchanged with both nil and real HTTP requests

Policy merge tests:
- TestGetFederationToken_GetPoliciesForUser: tests IAMManager.GetPoliciesForUser
  with no user store (error), missing user, user with policies, user without
- TestGetFederationToken_PolicyMergeAndDedup: tests that identity.PolicyNames
  and IAM-manager-resolved policies are merged and deduplicated (SharedPolicy
  appears in both sources, result has 3 unique policies)
- TestGetFederationToken_PolicyMergeNoManager: tests that when IAM manager is
  unavailable, identity.PolicyNames alone are embedded

* test(s3): add end-to-end integration tests for GetFederationToken

Add integration tests that call GetFederationToken using real AWS SigV4
signed HTTP requests against a running SeaweedFS instance, following the
existing pattern in test/s3/iam/s3_sts_assume_role_test.go.

Tests:
- TestSTSGetFederationTokenValidation: missing name, name too short/long,
  invalid characters, duration too short/long, malformed policy, anonymous
  rejection (7 subtests)
- TestSTSGetFederationTokenRejectTemporaryCredentials: obtains temp creds
  via AssumeRole then verifies GetFederationToken rejects them
- TestSTSGetFederationTokenSuccess: basic success, custom 1h duration,
  36h max duration with expiration time verification
- TestSTSGetFederationTokenWithSessionPolicy: creates a bucket, obtains
  federated creds with GetObject-only session policy, verifies GetObject
  succeeds and PutObject is denied using the AWS SDK S3 client

Chris LuandGitHub a4b896a224 fix(s3): skip directories before marker in ListObjectVersions pagination (#8890)
* fix(s3): skip directories before marker in ListObjectVersions pagination

ListObjectVersions was re-traversing the entire directory tree from the
beginning on every paginated request, only skipping entries at the leaf
level. For buckets with millions of objects in deep hierarchies, this
caused exponentially slower responses as pagination progressed.

Two optimizations:
1. Use keyMarker to compute a startFrom position at each directory level,
   skipping directly to the relevant entry instead of scanning from the
   beginning (mirroring how ListObjects uses marker descent).
2. Skip recursing into subdirectories whose keys are entirely before the
   keyMarker.

Changes per-page cost from O(entries_before_marker) to O(tree_depth).

* test(s3): add integration test for deep-hierarchy version listing pagination

Adds TestVersioningPaginationDeepDirectoryHierarchy which creates objects
across 20 subdirectories at depth 6 (mimicking Veeam 365 backup layout)
and paginates through them with small maxKeys. Verifies correctness
(no duplicates, sorted order, all objects found) and checks that later
pages don't take dramatically longer than earlier ones — the symptom
of the pre-fix re-traversal bug. Also tests delimiter+pagination
interaction across subdirectories.

* test(s3): strengthen deep-hierarchy pagination assertions

- Replace timing warning (t.Logf) with a failing assertion (t.Errorf)
  so pagination regressions actually fail the test.
- Replace generic count/uniqueness/sort checks on CommonPrefixes with
  exact equality against the expected prefix slice, catching wrong-but-
  sorted results.

* test(s3): use allKeys for exact assertion in deep-hierarchy pagination test

Wire the allKeys slice (previously unused dead code) into the version
listing assertion, replacing generic count/uniqueness/sort checks with
an exact equality comparison against the keys that were created.

Chris LuandGitHub 7c59b639c9 STS: add GetCallerIdentity support (#8893)
* STS: add GetCallerIdentity support

Implement the AWS STS GetCallerIdentity action, which returns the
ARN, account ID, and user ID of the caller based on SigV4 authentication.
This is commonly used by AWS SDKs and CLI tools (e.g. `aws sts get-caller-identity`)
to verify credentials and determine the authenticated identity.

* test: remove trivial GetCallerIdentity tests

Remove the XML unmarshal test (we don't consume this response as input)
and the routing constant test (just asserts a literal equals itself).

* fix: route GetCallerIdentity through STS in UnifiedPostHandler and use stable UserId

- UnifiedPostHandler only dispatched actions starting with "AssumeRole" to STS,
  so GetCallerIdentity in a POST body would fall through to the IAM path and
  get AccessDenied for non-admin users. Add explicit check for GetCallerIdentity.
- Use identity.Name as UserId instead of credential.AccessKey, which is a
  transient value and incorrect for STS assumed-role callers.

Chris LuandGitHub ab4e52ae2f fix(s3): use recursive delete for .versions directory cleanup (#8887)
* fix(s3): use recursive delete for .versions directory cleanup

When only delete markers remain in a .versions directory,
updateLatestVersionAfterDeletion tried to delete it non-recursively,
which failed with "fail to delete non-empty folder" because the delete
marker entries were still present. Use recursive deletion so the
directory and its remaining delete marker entries are cleaned up together.

* fix(s3): guard .versions directory deletion against truncated listings

When the version listing is truncated (>1000 entries), content versions
may exist beyond the first page. Skip the recursive directory deletion
in this case to prevent data loss.

* fix(s3): preserve delete markers in .versions directory

Delete markers must be preserved per S3 semantics — they are only
removed by an explicit DELETE with versionId. The previous fix would
recursively delete the entire .versions directory (including delete
markers) when no content versions were found.

Now the logic distinguishes three cases:
1. Content versions exist → update latest version metadata
2. Only delete markers remain (or listing truncated) → keep directory
3. Truly empty → safe to delete directory (non-recursive)

Chris LuandGitHub efbed39e25 S3: map canned ACL to file permissions and add configurable default file mode (#8886)
* S3: map canned ACL to file permissions and add configurable default file mode

S3 uploads were hardcoded to 0660 regardless of ACL headers. Now the
X-Amz-Acl header maps to Unix file permissions per-object:
- public-read, authenticated-read, bucket-owner-read → 0644
- public-read-write → 0666
- private, bucket-owner-full-control → 0660

Also adds -defaultFileMode / -s3.defaultFileMode flag to set a
server-wide default when no ACL header is present.

Closes #8874

* Address review feedback for S3 file mode feature

- Extract hardcoded 0660 to defaultFileMode constant
- Change parseDefaultFileMode to return error instead of calling Fatalf
- Add -s3.defaultFileMode flag to filer.go and mini.go (was missing)
- Add doc comment to S3Options about updating all four flag sites
- Add TestResolveFileMode with 10 test cases covering ACL mapping,
  server default, and priority ordering

Chris LuandGitHub e8a6fcaafb s3api: skip TTL fast-path for versioned buckets (#8823)
* 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.

297cdef1a3 s3api: accept all supported lifecycle rule types (#8813)
* s3api: accept NoncurrentVersionExpiration, AbortIncompleteMultipartUpload, Expiration.Date

Update PutBucketLifecycleConfigurationHandler to accept all newly-supported
lifecycle rule types. Only Transition and NoncurrentVersionTransition are
still rejected (require storage class tier infrastructure).

Changes:
- Remove ErrNotImplemented for Expiration.Date (handled by worker at scan time)
- Only reject rules with Transition.set or NoncurrentVersionTransition.set
- Extract prefix from Filter.And when present
- Add comment explaining that non-Expiration.Days rules are evaluated by
  the lifecycle worker from stored lifecycle XML, not via filer.conf TTL

The lifecycle XML is already stored verbatim in bucket metadata, so new
rule types are preserved on Get even without explicit handler support.
Filer.conf TTL entries are only created for Expiration.Days (fast path).

* s3api: skip TTL fast path for rules with tag or size filters

Rules with tag or size constraints (Filter.Tag, Filter.And with tags
or size bounds, Filter.ObjectSizeGreaterThan/LessThan) must not be
lowered to filer.conf TTL entries, because TTL applies unconditionally
to all objects under the prefix. These rules are evaluated at scan
time by the lifecycle worker which checks each object's tags and size.

Only simple Expiration.Days rules with prefix-only filters use the
TTL fast path (RocksDB compaction filter).

782ab84f95 lifecycle worker: drive MPU abort from lifecycle rules (#8812)
* lifecycle worker: drive MPU abort from lifecycle rules

Update the multipart upload abort phase to read
AbortIncompleteMultipartUpload.DaysAfterInitiation from the parsed
lifecycle rules. Falls back to the worker config abort_mpu_days when
no lifecycle XML rule specifies the value.

This means per-bucket MPU abort thresholds are now respected when
set via PutBucketLifecycleConfiguration, instead of using a single
global worker config value for all buckets.

* lifecycle worker: only use config AbortMPUDays when no lifecycle XML exists

When a bucket has lifecycle XML (useRuleEval=true) but no
AbortIncompleteMultipartUpload rule, mpuAbortDays should be 0
(no abort), not the worker config default. The config fallback
should only apply to buckets without lifecycle XML.

* lifecycle worker: only skip .uploads at bucket root

* lifecycle worker: use per-upload rule evaluation for MPU abort

Replace the single bucket-wide mpuAbortDays with per-upload evaluation
using s3lifecycle.EvaluateMPUAbort, which respects each rule's prefix
filter and DaysAfterInitiation threshold.

Previously the code took the first enabled abort rule's days value
and applied it to all uploads, ignoring prefix scoping and multiple
rules with different thresholds.

Config fallback (abort_mpu_days) now only applies when lifecycle XML
is truly absent (xmlPresent=false), not when XML exists but has no
abort rules.

Also fix EvaluateMPUAbort to use expectedExpiryTime for midnight-UTC
semantics matching other lifecycle cutoffs.

f52a3c87ce lifecycle worker: fix ExpiredObjectDeleteMarker to match AWS semantics (#8811)
* lifecycle worker: add NoncurrentVersionExpiration support

Add version-aware scanning to the rule-based execution path. When the
walker encounters a .versions directory, processVersionsDirectory():
- Lists all version entries (v_<versionId>)
- Sorts by version timestamp (newest first)
- Walks non-current versions with ShouldExpireNoncurrentVersion()
  which handles both NoncurrentDays and NewerNoncurrentVersions
- Extracts successor time from version IDs (both old/new format)
- Skips delete markers in noncurrent version counting
- Falls back to entry Mtime when version ID timestamp is unavailable

Helper functions:
- sortVersionsByTimestamp: insertion sort by version ID timestamp
- getEntryVersionTimestamp: extracts timestamp with Mtime fallback

* lifecycle worker: address review feedback for noncurrent versions

- Use sentinel errLimitReached in versions directory handler
- Set NoncurrentIndex on ObjectInfo for proper NewerNoncurrentVersions
  evaluation

* lifecycle worker: fail closed on XML parse error, guard zero Mtime

- Fail closed when lifecycle XML exists but fails to parse, instead
  of falling back to TTL which could apply broader rules
- Guard Mtime > 0 before using time.Unix(mtime, 0) to avoid mapping
  unset Mtime to 1970, which would misorder versions and cause
  premature expiration

* lifecycle worker: count delete markers toward NoncurrentIndex

Noncurrent delete markers should count toward the
NewerNoncurrentVersions retention threshold so data versions
get the correct position index. Previously, skipping delete
markers without incrementing the index could retain too many
versions after delete/recreate cycles.

* lifecycle worker: fix version ordering, error propagation, and fail-closed scope

1. Use full version ID comparison (CompareVersionIds) for sorting
   .versions entries, not just decoded timestamps. Two versions with
   the same timestamp prefix but different random suffixes were
   previously misordered, potentially treating the newest version as
   noncurrent and deleting it.

2. Propagate .versions listing failures to the caller instead of
   swallowing them with (nil, 0). Transient filer errors on a
   .versions directory now surface in the job result.

3. Narrow the fail-closed path to only malformed lifecycle XML
   (errMalformedLifecycleXML). Transient filer LookupEntry errors
   now fall back to TTL with a warning, matching the original intent
   of "fail closed on bad config, not on network blips."

* lifecycle worker: only skip .uploads at bucket root

* lifecycle worker: sort.Slice, mixed-format test, XML presence tracking

- Replace manual insertion sort with sort.Slice in sortVersionsByVersionId
- Add TestCompareVersionIdsMixedFormats covering old/new format ordering
- Distinguish "no lifecycle XML" (nil) from "XML present but no effective
  rules" (non-nil empty slice) so buckets with all-disabled rules don't
  incorrectly fall back to filer.conf TTL expiration

* lifecycle worker: guard nil Attributes, use TrimSuffix in test

- Guard entry.Attributes != nil before accessing GetFileSize() and
  Mtime in both listExpiredObjectsByRules and processVersionsDirectory
- Use strings.TrimPrefix/TrimSuffix in TestVersionsDirectoryNaming
  to match the production code pattern

* lifecycle worker: skip TTL scan when XML present, fix test assertions

- When lifecycle XML is present but has no effective rules, skip
  object scanning entirely instead of falling back to TTL path
- Test sort output against concrete expected names instead of
  re-using the same comparator as the sort itself

* lifecycle worker: fix ExpiredObjectDeleteMarker to match AWS semantics

Rewrite cleanupDeleteMarkers() to only remove delete markers that are
the sole remaining version of an object. Previously, delete markers
were removed unconditionally which could resurface older versions in
versioned buckets.

New algorithm:
1. Walk bucket tree looking for .versions directories
2. Check ExtLatestVersionIsDeleteMarker from directory metadata
3. Count versions in the .versions directory
4. Only remove if count == 1 (delete marker is sole version)
5. Require an ExpiredObjectDeleteMarker=true rule (when lifecycle
   XML rules are present)
6. Remove the empty .versions directory after cleanup

This phase runs after NoncurrentVersionExpiration so version counts
are accurate.

* lifecycle worker: respect prefix filter in ExpiredObjectDeleteMarker rules

Previously hasDeleteMarkerRule was a bucket-wide boolean that ignored
rule prefixes. A prefix-scoped rule like "logs/" would incorrectly
clean up delete markers in all paths.

Add matchesDeleteMarkerRule() that checks if a matching enabled
ExpiredObjectDeleteMarker rule exists for the specific object key,
respecting the rule's prefix filter. Falls back to legacy behavior
(allow cleanup) when no lifecycle XML rules are provided.

* lifecycle worker: only skip .uploads at bucket root

Check dir == bucketPath before skipping directories named .uploads.
Previously a user-created directory like data/.uploads/ at any depth
would be incorrectly skipped during lifecycle scanning.

* lifecycle worker: fix delete marker cleanup with XML-present empty rules

1. matchesDeleteMarkerRule now uses nil check (not len==0) for legacy
   fallback. A non-nil empty slice means lifecycle XML was present but
   had no ExpiredObjectDeleteMarker rules, so cleanup is blocked.
   Previously, an empty slice triggered the legacy true path.

2. Use per-directory removedHere flag instead of cumulative cleaned
   counter when deciding to remove .versions directories. Previously,
   after the first successful cleanup anywhere in the bucket, every
   subsequent .versions directory would be removed even if its own
   delete marker was not actually deleted.

* lifecycle worker: use full filter matching for delete marker rules

matchesDeleteMarkerRule now uses s3lifecycle.MatchesFilter (exported)
instead of prefix-only matching. This ensures tag and size filters
on ExpiredObjectDeleteMarker rules are respected, preventing broader
deletions than the configured policy intends.

Add TestMatchesDeleteMarkerRule covering: nil rules (legacy), empty
rules (XML present), prefix match/mismatch, disabled rules, rules
without the flag, and tag-filtered rules against tagless markers.

   (errMalformedLifecycleXML). Transient filer LookupEntry errors
   now fall back to TTL with a warning, matching the original intent
   of "fail closed on bad config, not on network blips."

* lifecycle worker: only skip .uploads at bucket root

* lifecycle worker: sort.Slice, mixed-format test, XML presence tracking

- Replace manual insertion sort with sort.Slice in sortVersionsByVersionId
- Add TestCompareVersionIdsMixedFormats covering old/new format ordering
- Distinguish "no lifecycle XML" (nil) from "XML present but no effective
  rules" (non-nil empty slice) so buckets with all-disabled rules don't
  incorrectly fall back to filer.conf TTL expiration

* lifecycle worker: guard nil Attributes, use TrimSuffix in test

- Guard entry.Attributes != nil before accessing GetFileSize() and
  Mtime in both listExpiredObjectsByRules and processVersionsDirectory
- Use strings.TrimPrefix/TrimSuffix in TestVersionsDirectoryNaming
  to match the production code pattern

* lifecycle worker: skip TTL scan when XML present, fix test assertions

- When lifecycle XML is present but has no effective rules, skip
  object scanning entirely instead of falling back to TTL path
- Test sort output against concrete expected names instead of
  re-using the same comparator as the sort itself

54dd4f091d s3lifecycle: add lifecycle rule evaluator package and extend XML types (#8807)
* s3api: extend lifecycle XML types with NoncurrentVersionExpiration, AbortIncompleteMultipartUpload

Add missing S3 lifecycle rule types to the XML data model:
- NoncurrentVersionExpiration with NoncurrentDays and NewerNoncurrentVersions
- NoncurrentVersionTransition with NoncurrentDays and StorageClass
- AbortIncompleteMultipartUpload with DaysAfterInitiation
- Filter.ObjectSizeGreaterThan and ObjectSizeLessThan
- And.ObjectSizeGreaterThan and ObjectSizeLessThan
- Filter.UnmarshalXML to properly parse Tag, And, and size filter elements

Each new type follows the existing set-field pattern for conditional
XML marshaling. No behavior changes - these types are not yet wired
into handlers or the lifecycle worker.

* s3lifecycle: add lifecycle rule evaluator package

New package weed/s3api/s3lifecycle/ provides a pure-function lifecycle
rule evaluation engine. The evaluator accepts flattened Rule structs and
ObjectInfo metadata, and returns the appropriate Action.

Components:
- evaluator.go: Evaluate() for per-object actions with S3 priority
  ordering (delete marker > noncurrent version > current expiration),
  ShouldExpireNoncurrentVersion() with NewerNoncurrentVersions support,
  EvaluateMPUAbort() for multipart upload rules
- filter.go: prefix, tag, and size-based filter matching
- tags.go: ExtractTags() extracts S3 tags from filer Extended metadata,
  HasTagRules() for scan-time optimization
- version_time.go: GetVersionTimestamp() extracts timestamps from
  SeaweedFS version IDs (both old and new format)

Comprehensive test coverage: 54 tests covering all action types,
filter combinations, edge cases, and version ID formats.

* s3api: add UnmarshalXML for Expiration, Transition, ExpireDeleteMarker

Add UnmarshalXML methods that set the internal 'set' flag during XML
parsing. Previously these flags were only set programmatically, causing
XML round-trip to drop elements. This ensures lifecycle configurations
stored as XML survive unmarshal/marshal cycles correctly.

Add comprehensive XML round-trip tests for all lifecycle rule types
including NoncurrentVersionExpiration, AbortIncompleteMultipartUpload,
Filter with Tag/And/size constraints, and a complete Terraform-style
lifecycle configuration.

* s3lifecycle: address review feedback

- Fix version_time.go overflow: guard timestampPart > MaxInt64 before
  the inversion subtraction to prevent uint64 wrap
- Make all expiry checks inclusive (!now.Before instead of now.After)
  so actions trigger at the exact scheduled instant
- Add NoncurrentIndex to ObjectInfo so Evaluate() can properly handle
  NewerNoncurrentVersions via ShouldExpireNoncurrentVersion()
- Add test for high-bit overflow version ID

* s3lifecycle: guard ShouldExpireNoncurrentVersion against zero SuccessorModTime

Add early return when obj.IsLatest or obj.SuccessorModTime.IsZero()
to prevent premature expiration of versions with uninitialized
successor timestamps (zero value would compute to epoch, always expired).

Chris LuandGitHub 7d5cbfd547 s3: support s3:x-amz-server-side-encryption policy condition (#8806)
* s3: support s3:x-amz-server-side-encryption policy condition (#7680)

- Normalize x-amz-server-side-encryption header values to canonical form
  (aes256 → AES256, aws:kms mixed-case → aws:kms) so StringEquals
  conditions work regardless of client capitalisation
- Exempt UploadPart and UploadPartCopy from SSE Null conditions: these
  actions inherit SSE from the initial CreateMultipartUpload request and
  do not re-send the header, so Deny/Null("true") should not block them
- Add sse_condition_test.go covering StringEquals, Null, case-insensitive
  normalisation, and multipart continuation action exemption

* s3: address review comments on SSE condition support

- Replace "inherited" sentinel in injectSSEForMultipart with "AES256" so
  that StringEquals/Null conditions evaluate against a meaningful value;
  add TODO noting that KMS multipart uploads need the actual algorithm
  looked up from the upload state
- Rewrite TestSSECaseInsensitiveNormalization to drive normalisation
  through EvaluatePolicyForRequest with a real *http.Request so regressions
  in the production code path are caught; split into AES256 and aws:kms
  variants to cover both normalisation branches

* s3: plumb real inherited SSE from multipart upload state into policy eval

Instead of injecting a static "AES256" sentinel for UploadPart/UploadPartCopy,
look up the actual SSE algorithm from the stored CreateMultipartUpload entry
and pass it through the evaluation chain.

Changes:
- PolicyEvaluationArgs gains InheritedSSEAlgorithm string; set by the
  BucketPolicyEngine wrapper for multipart continuation actions
- injectSSEForMultipart(conditions, inheritedSSE) now accepts the real
  algorithm; empty string means no SSE → Null("true") fires correctly
- IsMultipartContinuationAction exported so the s3api wrapper can use it
- BucketPolicyEngine gets a MultipartSSELookup callback (set by S3ApiServer)
  that fetches the upload entry and reads SeaweedFSSSEKMSKeyID /
  SeaweedFSSSES3Encryption to determine the algorithm
- S3ApiServer.getMultipartSSEAlgorithm implements the lookup via getEntry
- Tests updated: three multipart cases (AES256, aws:kms, no-SSE-must-deny)
  plus UploadPartCopy coverage

17028fbf59 fix: serialize SSE-KMS metadata when bucket default encryption applies KMS (#8780)
* fix: serialize SSE-KMS metadata when bucket default encryption applies KMS

When a bucket has default SSE-KMS encryption enabled and a file is uploaded
without explicit SSE headers, the encryption was applied correctly but the
SSE-KMS metadata (x-seaweedfs-sse-kms-key) was not serialized. This caused
downloads to fail with "empty SSE-KMS metadata" because the entry's Extended
map stored an empty byte slice.

The existing code already handled this for SSE-S3 bucket defaults
(SerializeSSES3Metadata) but was missing the equivalent call to
SerializeSSEKMSMetadata for the KMS path.

Fixes seaweedfs/seaweedfs#8776

* ci: add KMS integration tests to GitHub Actions

Add a kms-tests.yml workflow that runs on changes to KMS/SSE code with
two jobs:

1. KMS provider tests: starts OpenBao via Docker, runs Go integration
   tests in test/kms/ against a real KMS backend
2. S3 KMS e2e tests: starts OpenBao + weed mini built from source, runs
   test_s3_kms.sh which covers bucket-default SSE-KMS upload/download
   (the exact scenario from #8776)

Supporting changes:
- test/kms/Makefile: add CI targets (test-provider-ci, test-s3-kms-ci)
  that manage OpenBao via plain Docker and run weed from source
- test/kms/s3-config-openbao-template.json: S3 config template with
  OpenBao KMS provider for weed mini

* refactor: combine SSE-S3 and SSE-KMS metadata serialization into else-if

SSE-S3 and SSE-KMS bucket default encryption are mutually exclusive, so
use a single if/else-if block instead of two independent if blocks.

* Update .github/workflows/kms-tests.yml

* fix(ci): start weed mini from data dir to avoid Docker filer.toml

weed mini reads filer.toml from the current working directory first.
When running from test/kms/, it picked up the Docker-targeted filer.toml
which has dir="/data/filerdb" (a path that doesn't exist in CI), causing
a fatal crash at filer store initialization.

Fix by cd-ing to the data directory before starting weed mini.
Also improve log visibility on failure.

28fe92065a S3: reject part uploads after AbortMultipartUpload (#8768)
* S3: reject part uploads after AbortMultipartUpload

PutObjectPartHandler did not verify that the multipart upload session
still exists before accepting parts. After AbortMultipartUpload deleted
the upload directory, the ErrNotFound from getEntry was silently ignored
(treated as "may be non-SSE upload"), allowing parts to be stored as
orphaned files.

Now return ErrNoSuchUpload when the upload directory is not found,
matching AWS S3 behavior.

Fixes #8766

* S3: check upload existence unconditionally in PutObjectPartHandler

Move the getEntry call out of the SSE-type conditional so the upload
existence check runs for all part uploads, including SSE-C. Previously
the SSE-C path skipped the check entirely, allowing parts to be uploaded
after abort when SSE-C headers were present.

Also flattens the nested SSE branching by one level now that getEntry
is called once upfront.

* S3: address PR review feedback for PutObjectPartHandler

- Log at error level when getEntry fails with an unexpected error,
  since we return ErrInternalError to the client
- Distinguish base IV decode errors from length validation failures
  with separate, clearer error messages

Chris LuandGitHub 0b3867dca3 filer: add structured error codes to CreateEntryResponse (#8767)
* filer: add FilerError enum and error_code field to CreateEntryResponse

Add a machine-readable error code alongside the existing string error
field. This follows the precedent set by PublishMessageResponse in the
MQ broker proto. The string field is kept for human readability and
backward compatibility.

Defined codes: OK, ENTRY_NAME_TOO_LONG, PARENT_IS_FILE,
EXISTING_IS_DIRECTORY, EXISTING_IS_FILE, ENTRY_ALREADY_EXISTS.

* filer: add sentinel errors and error code mapping in filer_pb

Define sentinel errors (ErrEntryNameTooLong, ErrParentIsFile, etc.) in
the filer_pb package so both the filer and consumers can reference them
without circular imports.

Add FilerErrorToSentinel() to map proto error codes to sentinels, and
update CreateEntryWithResponse() to check error_code first, falling back
to the string-based path for backward compatibility with old servers.

* filer: return wrapped sentinel errors and set proto error codes

Replace fmt.Errorf string errors in filer.CreateEntry, UpdateEntry, and
ensureParentDirectoryEntry with wrapped filer_pb sentinel errors (using
%w). This preserves errors.Is() traversal on the server side.

In the gRPC CreateEntry handler, map sentinel errors to the
corresponding FilerError proto codes using errors.Is(), setting both
resp.Error (string, for backward compat) and resp.ErrorCode (enum).

* S3: use errors.Is() with filer sentinels instead of string matching

Replace fragile string-based error matching in filerErrorToS3Error and
other S3 API consumers with errors.Is() checks against filer_pb sentinel
errors. This works because the updated CreateEntryWithResponse helper
reconstructs sentinel errors from the proto FilerError code.

Update iceberg stage_create and metadata_files to check resp.ErrorCode
instead of parsing resp.Error strings. Update SSE-S3 to use errors.Is()
for the already-exists check.

String matching is retained only for non-filer errors (gRPC transport
errors, checksum validation) that don't go through CreateEntryResponse.

* filer: remove backward-compat string fallbacks for error codes

Clients and servers are always deployed together, so there is no need
for backward-compatibility fallback paths that parse resp.Error strings
when resp.ErrorCode is unset. Simplify all consumers to rely solely on
the structured error code.

* iceberg: ensure unknown non-OK error codes are not silently ignored

When FilerErrorToSentinel returns nil for an unrecognized error code,
return an error including the code and message rather than falling
through to return nil.

* filer: fix redundant error message and restore error wrapping in helper

Use request path instead of resp.Error in the sentinel error format
string to avoid duplicating the sentinel message (e.g. "entry already
exists: entry already exists"). Restore %w wrapping with errors.New()
in the fallback paths so callers can use errors.Is()/errors.As().

* filer: promote file to directory on path conflict instead of erroring

S3 allows both "foo/bar" (object) and "foo/bar/xyzzy" (another object)
to coexist because S3 has a flat key space. When ensureParentDirectoryEntry
finds a parent path that is a file instead of a directory, promote it to
a directory by setting ModeDir while preserving the original content and
chunks. Use Store.UpdateEntry directly to bypass the Filer.UpdateEntry
type-change guard.

This fixes the S3 compatibility test failures where creating overlapping
keys (e.g. "foo/bar" then "foo/bar/xyzzy") returned ExistingObjectIsFile.

Chris LuandGitHub 152884eff2 S3: add s3: prefix to x-amz-* condition keys for AWS compatibility (#8765)
AWS S3 policy conditions reference request headers with the s3: namespace
prefix (e.g., s3:x-amz-server-side-encryption). The extraction code was
storing these headers without the prefix, so bucket policy conditions
using the standard AWS key names would never match.

Chris LuandGitHub 2877febd73 S3: fix silent PutObject failure and enforce 1024-byte key limit (#8764)
* S3: add KeyTooLongError error code

Add ErrKeyTooLongError (HTTP 400, code "KeyTooLongError") to match the
standard AWS S3 error for object keys that exceed length limits.

* S3: fix silent PutObject failure when entry name exceeds max_file_name_length

putToFiler called client.CreateEntry() directly and discarded the gRPC
response. The filer embeds application errors like "entry name too long"
in resp.Error (not as gRPC transport errors), so the error was silently
swallowed and clients received HTTP 200 with an ETag for objects that
were never stored.

Switch to the filer_pb.CreateEntry() helper which properly checks
resp.Error, and map "entry name too long" to KeyTooLongError (HTTP 400).

To avoid fragile string parsing across the gRPC boundary, define shared
error message constants in weed/util/constants and use them in both the
filer (producing errors) and S3 API (matching errors). Switch
filerErrorToS3Error to use strings.Contains/HasSuffix with these
constants so matches work regardless of any wrapper prefix. Apply
filerErrorToS3Error to the mkdir path for directory markers.

Fixes #8759

* S3: enforce 1024-byte maximum object key length

AWS S3 limits object keys to 1024 bytes. Add early validation on write
paths (PutObject, CopyObject, CreateMultipartUpload) to reject keys
exceeding the limit with the standard KeyTooLongError (HTTP 400).

The key length check runs before bucket auto-creation to prevent
overlong keys from triggering unnecessary side effects.

Also use filerErrorToS3Error for CopyObject's mkFile error paths so
name-too-long errors from the filer return KeyTooLongError instead of
InternalError.

Ref #8758

* S3: add handler-level tests for key length validation and error mapping

Add tests for filerErrorToS3Error mapping "entry name too long" to
KeyTooLongError, including a regression test for the CreateEntry-prefixed
"existing ... is a directory" form. Add handler-level integration tests
that exercise PutObjectHandler, CopyObjectHandler, and
NewMultipartUploadHandler via httptest, verifying HTTP 400 and
KeyTooLongError XML response for overlong keys and acceptance of keys at
the 1024-byte limit.

Chris LuandGitHub e5f72077ee fix: resolve CORS cache race condition causing stale 404 responses (#8748)
The metadata subscription handler (updateBucketConfigCacheFromEntry) was
making a separate RPC call via loadCORSFromBucketContent to load CORS
configuration. This created a race window where a slow CreateBucket
subscription event could re-cache stale data after PutBucketCors had
already cleared the cache, causing subsequent GetBucketCors to return
404 NoSuchCORSConfiguration.

Parse CORS directly from the subscription entry's Content field instead
of making a separate RPC. Also fix getBucketConfig to parse CORS from
the already-fetched entry, eliminating a redundant RPC call.

Fix TestCORSCaching to use require.NoError to prevent nil pointer
dereference panics when GetBucketCors fails.

Chris LuandGitHub 80f3079d2a fix(s3): include directory markers in ListObjects without delimiter (#8704)
* fix(s3): include directory markers in ListObjects without delimiter (#8698)

Directory key objects (zero-byte objects with keys ending in "/") created
via PutObject were omitted from ListObjects/ListObjectsV2 results when no
delimiter was specified. AWS S3 includes these as regular keys in Contents.

The issue was in doListFilerEntries: when recursing into directories in
non-delimiter mode, directory key objects were only emitted when
prefixEndsOnDelimiter was true. Added an else branch to emit them in the
general recursive case as well.

* remove issue reference from inline comment

* test: add child-under-marker and paginated listing coverage

Extend test 6 to place a child object under the directory marker
and paginate with MaxKeys=1 so the emit-then-recurse truncation
path is exercised.

* fix(test): skip directory markers in Spark temporary artifacts check

The listing check now correctly shows directory markers (keys ending
in "/") after the ListObjects fix. These 0-byte metadata objects are
not data artifacts — filter them from the listing check since the
HeadObject-based check already verifies their cleanup with a timeout.

Chris LuandGitHub c197206897 fix(s3): return ETag header for directory marker PutObject requests (#8688)
* fix(s3): return ETag header for directory marker PutObject requests

The PutObject handler has a special path for keys ending with "/" (directory
markers) that creates the entry via mkdir. This path never computed or set
the ETag response header, unlike the regular PutObject path. AWS S3 always
returns an ETag header, even for empty-body puts.

Compute the MD5 of the content (empty or otherwise), store it in the entry
attributes and extended attributes, and set the ETag response header.

Change NotResource from value type to pointer (*StringOrStringSlice) so
that omitempty properly omits it when unset, matching the existing
Principal field pattern. This prevents IaC tools (Terraform, Ansible)
from detecting false configuration drift.

Add bucket policy round-trip idempotency integration tests.

* simplify JSON comparison in bucket policy idempotency test

Use require.JSONEq directly on the raw JSON strings instead of
round-tripping through unmarshal/marshal, since JSONEq already
handles normalization internally.

* fix bucket policy test cases that locked out the admin user

The Deny+NotResource test cases used Action:"s3:*" which denied the
admin's own GetBucketPolicy call. Scope deny to s3:GetObject only,
and add an Allow+NotResource variant instead.

* fix(s3): also make Resource a pointer to fix empty string in JSON

Apply the same omitempty pointer fix to the Resource field, which was
emitting "Resource":"" when only NotResource was set. Add
NewStringOrStringSlicePtr helper, make Strings() nil-safe, and handle
*StringOrStringSlice in normalizeToStringSliceWithError.

* improve bucket policy integration tests per review feedback

- Replace time.Sleep with waitForClusterReady using ListBuckets
- Use structural hasKey check instead of brittle substring NotContains
- Assert specific NoSuchBucketPolicy error code after delete
- Handle single-statement policies in hasKey helper

8cde3d4486 Add data file compaction to iceberg maintenance (Phase 2) (#8503)
* Add iceberg_maintenance plugin worker handler (Phase 1)

Implement automated Iceberg table maintenance as a new plugin worker job
type. The handler scans S3 table buckets for tables needing maintenance
and executes operations in the correct Iceberg order: expire snapshots,
remove orphan files, and rewrite manifests.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* Add data file compaction to iceberg maintenance handler (Phase 2)

Implement bin-packing compaction for small Parquet data files:
- Enumerate data files from manifests, group by partition
- Merge small files using parquet-go (read rows, write merged output)
- Create new manifest with ADDED/DELETED/EXISTING entries
- Commit new snapshot with compaction metadata

Add 'compact' operation to maintenance order (runs before expire_snapshots),
configurable via target_file_size_bytes and min_input_files thresholds.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* Fix memory exhaustion in mergeParquetFiles by processing files sequentially

Previously all source Parquet files were loaded into memory simultaneously,
risking OOM when a compaction bin contained many small files. Now each file
is loaded, its rows are streamed into the output writer, and its data is
released before the next file is loaded — keeping peak memory proportional
to one input file plus the output buffer.

* Validate bucket/namespace/table names against path traversal

Reject names containing '..', '/', or '\' in Execute to prevent
directory traversal via crafted job parameters.

* Add filer address failover in iceberg maintenance handler

Try each filer address from cluster context in order instead of only
using the first one. This improves resilience when the primary filer
is temporarily unreachable.

* Add separate MinManifestsToRewrite config for manifest rewrite threshold

The rewrite_manifests operation was reusing MinInputFiles (meant for
compaction bin file counts) as its manifest count threshold. Add a
dedicated MinManifestsToRewrite field with its own config UI section
and default value (5) so the two thresholds can be tuned independently.

* Fix risky mtime fallback in orphan removal that could delete new files

When entry.Attributes is nil, mtime defaulted to Unix epoch (1970),
which would always be older than the safety threshold, causing the
file to be treated as eligible for deletion. Skip entries with nil
Attributes instead, matching the safer logic in operations.go.

* Fix undefined function references in iceberg_maintenance_handler.go

Use the exported function names (ShouldSkipDetectionByInterval,
BuildDetectorActivity, BuildExecutorActivity) matching their
definitions in vacuum_handler.go.

* Remove duplicated iceberg maintenance handler in favor of iceberg/ subpackage

The IcebergMaintenanceHandler and its compaction code in the parent
pluginworker package duplicated the logic already present in the
iceberg/ subpackage (which self-registers via init()). The old code
lacked stale-plan guards, proper path normalization, CAS-based xattr
updates, and error-returning parseOperations.

Since the registry pattern (default "all") makes the old handler
unreachable, remove it entirely. All functionality is provided by
iceberg.Handler with the reviewed improvements.

* Fix MinManifestsToRewrite clamping to match UI minimum of 2

The clamp reset values below 2 to the default of 5, contradicting the
UI's advertised MinValue of 2. Clamp to 2 instead.

* Sort entries by size descending in splitOversizedBin for better packing

Entries were processed in insertion order which is non-deterministic
from map iteration. Sorting largest-first before the splitting loop
improves bin packing efficiency by filling bins more evenly.

* Add context cancellation check to drainReader loop

The row-streaming loop in drainReader did not check ctx between
iterations, making long compaction merges uncancellable. Check
ctx.Done() at the top of each iteration.

* Fix splitOversizedBin to always respect targetSize limit

The minFiles check in the split condition allowed bins to grow past
targetSize when they had fewer than minFiles entries, defeating the
OOM protection. Now bins always split at targetSize, and a trailing
runt with fewer than minFiles entries is merged into the previous bin.

* Add integration tests for iceberg table maintenance plugin worker

Tests start a real weed mini cluster, create S3 buckets and Iceberg
table metadata via filer gRPC, then exercise the iceberg.Handler
operations (ExpireSnapshots, RemoveOrphans, RewriteManifests) against
the live filer. A full maintenance cycle test runs all operations in
sequence and verifies metadata consistency.

Also adds exported method wrappers (testing_api.go) so the integration
test package can call the unexported handler methods.

* Fix splitOversizedBin dropping files and add source path to drainReader errors

The runt-merge step could leave leading bins with fewer than minFiles
entries (e.g. [80,80,10,10] with targetSize=100, minFiles=2 would drop
the first 80-byte file). Replace the filter-based approach with an
iterative merge that folds any sub-minFiles bin into its smallest
neighbor, preserving all eligible files.

Also add the source file path to drainReader error messages so callers
can identify which Parquet file caused a read/write failure.

* Harden integration test error handling

- s3put: fail immediately on HTTP 4xx/5xx instead of logging and
  continuing
- lookupEntry: distinguish NotFound (return nil) from unexpected RPC
  errors (fail the test)
- writeOrphan and orphan creation in FullMaintenanceCycle: check
  CreateEntryResponse.Error in addition to the RPC error

* go fmt
