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

10a30a83e1 s3api: add GetObjectAttributes API support (#8504)
* s3api: add error code and header constants for GetObjectAttributes

Add ErrInvalidAttributeName error code and header constants
(X-Amz-Object-Attributes, X-Amz-Max-Parts, X-Amz-Part-Number-Marker,
X-Amz-Delete-Marker) needed by the S3 GetObjectAttributes API.

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

* s3api: implement GetObjectAttributes handler

Add GetObjectAttributesHandler that returns selected object metadata
(ETag, Checksum, StorageClass, ObjectSize, ObjectParts) without
returning the object body. Follows the same versioning and conditional
header patterns as HeadObjectHandler.

The handler parses the X-Amz-Object-Attributes header to determine
which attributes to include in the XML response, and supports
ObjectParts pagination via X-Amz-Max-Parts and X-Amz-Part-Number-Marker.

Ref: https://docs.aws.amazon.com/AmazonS3/latest/API/API_GetObjectAttributes.html

* s3api: register GetObjectAttributes route

Register the GET /{object}?attributes route for the
GetObjectAttributes API, placed before other object query
routes to ensure proper matching.

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

* s3api: add integration tests for GetObjectAttributes

Test coverage:
- Basic: simple object with all attribute types
- MultipartObject: multipart upload with parts pagination
- SelectiveAttributes: requesting only specific attributes
- InvalidAttribute: server rejects invalid attribute names
- NonExistentObject: returns NoSuchKey for missing objects

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

* s3api: add versioned object test for GetObjectAttributes

Test puts two versions of the same object and verifies that:
- GetObjectAttributes returns the latest version by default
- GetObjectAttributes with versionId returns the specific version
- ObjectSize and VersionId are correct for each version

* s3api: fix combined conditional header evaluation per RFC 7232

Per RFC 7232:
- Section 3.4: If-Unmodified-Since MUST be ignored when If-Match is
  present (If-Match is the more accurate replacement)
- Section 3.3: If-Modified-Since MUST be ignored when If-None-Match is
  present (If-None-Match is the more accurate replacement)

Previously, all four conditional headers were evaluated independently.
This caused incorrect 412 responses when If-Match succeeded but
If-Unmodified-Since failed (should return 200 per AWS S3 behavior).

Fix applied to both validateConditionalHeadersForReads (GET/HEAD) and
validateConditionalHeaders (PUT) paths.

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

* s3api: add conditional header combination tests for GetObjectAttributes

Test the RFC 7232 combined conditional header semantics:
- If-Match=true + If-Unmodified-Since=false => 200 (If-Unmodified-Since ignored)
- If-None-Match=false + If-Modified-Since=true => 304 (If-Modified-Since ignored)
- If-None-Match=true + If-Modified-Since=false => 200 (If-Modified-Since ignored)
- If-Match=true + If-Unmodified-Since=true => 200
- If-Match=false => 412 regardless

* s3api: document Checksum attribute as not yet populated

Checksum is accepted in validation (so clients requesting it don't get
a 400 error, matching AWS behavior for objects without checksums) but
SeaweedFS does not yet store S3 checksums. Add a comment explaining
this and noting where to populate it when checksum storage is added.

* s3api: add s3:GetObjectAttributes IAM action for ?attributes query

Previously, GET /{object}?attributes resolved to s3:GetObject via the
fallback path since resolveFromQueryParameters had no case for the
"attributes" query parameter.

Add S3_ACTION_GET_OBJECT_ATTRIBUTES constant ("s3:GetObjectAttributes")
and a branch in resolveFromQueryParameters to return it for GET requests
with the "attributes" query parameter, so IAM policies can distinguish
GetObjectAttributes from GetObject.

* s3api: evaluate conditional headers after version resolution

Move conditional header evaluation (If-Match, If-None-Match, etc.) to
after the version resolution step in GetObjectAttributesHandler. This
ensures that when a specific versionId is requested, conditions are
checked against the correct version entry rather than always against
the latest version.

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

* s3api: use bounded HTTP client in GetObjectAttributes tests

Replace http.DefaultClient with a timeout-aware http.Client (10s) in
the signedGetObjectAttributes helper and testGetObjectAttributesInvalid
to prevent tests from hanging indefinitely.

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

* s3api: check attributes query before versionId in action resolver

Move the GetObjectAttributes action check before the versionId check
in resolveFromQueryParameters. This fixes GET /bucket/key?attributes&versionId=xyz
being incorrectly classified as s3:GetObjectVersion instead of
s3:GetObjectAttributes.

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

* s3api: add tests for versioned conditional headers and action resolver

Add integration test that verifies conditional headers (If-Match,
If-None-Match) are evaluated against the requested version entry, not
the latest version. This covers the fix in 55c409dec.

Add unit test for ResolveS3Action verifying that the attributes query
parameter takes precedence over versionId, so GET ?attributes&versionId
resolves to s3:GetObjectAttributes. This covers the fix in b92c61c95.

* s3api: guard negative chunk indices and rename PartsCount field

Add bounds checks for b.StartChunk >= 0 and b.EndChunk >= 0 in
buildObjectAttributesParts to prevent panics from corrupted metadata
with negative index values.

Rename ObjectAttributesParts.PartsCount to TotalPartsCount to match
the AWS SDK v2 Go field naming convention, while preserving the XML
element name "PartsCount" via the struct tag.

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

* s3api: reject malformed max-parts and part-number-marker headers

Return ErrInvalidMaxParts and ErrInvalidPartNumberMarker when the
X-Amz-Max-Parts or X-Amz-Part-Number-Marker headers contain
non-integer or negative values, matching ListObjectPartsHandler
behavior. Previously these were silently ignored with defaults.

53048ffffb Add md5 checksum validation support on PutObject and UploadPart (#8367)
* Add md5 checksum validation support on PutObject and UploadPart

Per the S3 specification, when a client sends a Content-MD5 header, the server must compare it against the MD5 of the received body and return BadDigest (HTTP 400) if they don't match.

SeaweedFS was silently accepting objects with incorrect Content-MD5 headers, which breaks data integrity verification for clients that rely on this feature (e.g. boto3). The error infrastructure (ErrBadDigest, ErrMsgBadDigest) already existed from PR #7306 but was never wired to an actual check.

This commit adds MD5 verification in putToFiler after the body is streamed and the MD5 is computed, and adds Content-MD5 header validation to PutObjectPartHandler (matching PutObjectHandler). Orphaned chunks are cleaned up on mismatch.

Refs: https://github.com/seaweedfs/seaweedfs/discussions/3908

* handle SSE, add uploadpart test

* s3 integration test: fix typo and add multipart upload checksum test

* s3api: move validateContentMd5 after GetBucketAndObject in PutObjectPartHandler

* s3api: move validateContentMd5 after GetBucketAndObject in PutObjectHandler

* s3api: fix MD5 validation for SSE uploads and logging in putToFiler

* add SSE test with checksum validation - mostly ai-generated

0d8588e3ae S3: Implement IAM defaults and STS signing key fallback (#8348)
* S3: Implement IAM defaults and STS signing key fallback logic

* S3: Refactor startup order to init SSE-S3 key manager before IAM

* S3: Derive STS signing key from KEK using HKDF for security isolation

* S3: Document STS signing key fallback in security.toml

* fix(s3api): refine anonymous access logic and secure-by-default behavior

- Initialize anonymous identity by default in `NewIdentityAccessManagement` to prevent nil pointer exceptions.
- Ensure `ReplaceS3ApiConfiguration` preserves the anonymous identity if not present in the new configuration.
- Update `NewIdentityAccessManagement` signature to accept `filerClient`.
- In legacy mode (no policy engine), anonymous defaults to Deny (no actions), preserving secure-by-default behavior.
- Use specific `LookupAnonymous` method instead of generic map lookup.
- Update tests to accommodate signature changes and verify improved anonymous handling.

* feat(s3api): make IAM configuration optional

- Start S3 API server without a configuration file if `EnableIam` option is set.
- Default to `Allow` effect for policy engine when no configuration is provided (Zero-Config mode).
- Handle empty configuration path gracefully in `loadIAMManagerFromConfig`.
- Add integration test `iam_optional_test.go` to verify empty config behavior.

* fix(iamapi): fix signature mismatch in NewIdentityAccessManagementWithStore

* fix(iamapi): properly initialize FilerClient instead of passing nil

* fix(iamapi): properly initialize filer client for IAM management

- Instead of passing `nil`, construct a `wdclient.FilerClient` using the provided `Filers` addresses.
- Ensure `NewIdentityAccessManagementWithStore` receives a valid `filerClient` to avoid potential nil pointer dereferences or limited functionality.

* clean: remove dead code in s3api_server.go

* refactor(s3api): improve IAM initialization, safety and anonymous access security

* fix(s3api): ensure IAM config loads from filer after client init

* fix(s3): resolve test failures in integration, CORS, and tagging tests

- Fix CORS tests by providing explicit anonymous permissions config
- Fix S3 integration tests by setting admin credentials in init
- Align tagging test credentials in CI with IAM defaults
- Added goroutine to retry IAM config load in iamapi server

* fix(s3): allow anonymous access to health targets and S3 Tables when identities are present

* fix(ci): use /healthz for Caddy health check in awscli tests

* iam, s3api: expose DefaultAllow from IAM and Policy Engine

This allows checking the global "Open by Default" configuration from
other components like S3 Tables.

* s3api/s3tables: support DefaultAllow in permission logic and handler

Updated CheckPermissionWithContext to respect the DefaultAllow flag
in PolicyContext. This enables "Open by Default" behavior for
unauthenticated access in zero-config environments. Added a targeted
unit test to verify the logic.

* s3api/s3tables: propagate DefaultAllow through handlers

Propagated the DefaultAllow flag to individual handlers for
namespaces, buckets, tables, policies, and tagging. This ensures
consistent "Open by Default" behavior across all S3 Tables API
endpoints.

* s3api: wire up DefaultAllow for S3 Tables API initialization

Updated registerS3TablesRoutes to query the global IAM configuration
and set the DefaultAllow flag on the S3 Tables API server. This
completes the end-to-end propagation required for anonymous access in
zero-config environments. Added a SetDefaultAllow method to
S3TablesApiServer to facilitate this.

* s3api: fix tests by adding DefaultAllow to mock IAM integrations

The IAMIntegration interface was updated to include DefaultAllow(),
breaking several mock implementations in tests. This commit fixes
the build errors by adding the missing method to the mocks.

* env

* ensure ports

* env

d664ca5ed3 fix: IAM authentication with AWS Signature V4 and environment credentials (#8099)
* fix: IAM authentication with AWS Signature V4 and environment credentials

Three key fixes for authenticated IAM requests to work:

1. Fix request body consumption before signature verification
   - iamMatcher was calling r.ParseForm() which consumed POST body
   - This broke AWS Signature V4 verification on subsequent reads
   - Now only check query string in matcher, preserving body for verification
   - File: weed/s3api/s3api_server.go

2. Preserve environment variable credentials across config reloads
   - After IAM mutations, config reload overwrote env var credentials
   - Extract env var loading into loadEnvironmentVariableCredentials()
   - Call after every config reload to persist credentials
   - File: weed/s3api/auth_credentials.go

3. Add authenticated IAM tests and test infrastructure
   - New TestIAMAuthenticated suite with AWS SDK + Signature V4
   - Dynamic port allocation for independent test execution
   - Flag reset to prevent state leakage between tests
   - CI workflow to run S3 and IAM tests separately
   - Files: test/s3/example/*, .github/workflows/s3-example-integration-tests.yml

All tests pass:
- TestIAMCreateUser (unauthenticated)
- TestIAMAuthenticated (with AWS Signature V4)
- S3 integration tests

* fmt

* chore: rename test/s3/example to test/s3/normal

* simplify: CI runs all integration tests in single job

* Update s3-example-integration-tests.yml

* ci: run each test group separately to avoid raft registry conflicts
