Chris Lu	ca84a8a713	S3: Directly read write volume servers (#7481 ) * Lazy Versioning Check, Conditional SSE Entry Fetch, HEAD Request Optimization * revert Reverted the conditional versioning check to always check versioning status Reverted the conditional SSE entry fetch to always fetch entry metadata Reverted the conditional versioning check to always check versioning status Reverted the conditional SSE entry fetch to always fetch entry metadata * Lazy Entry Fetch for SSE, Skip Conditional Header Check * SSE-KMS headers are present, this is not an SSE-C request (mutually exclusive) * SSE-C is mutually exclusive with SSE-S3 and SSE-KMS * refactor * Removed Premature Mutual Exclusivity Check * check for the presence of the X-Amz-Server-Side-Encryption header * not used * fmt * directly read write volume servers * HTTP Range Request Support * set header * md5 * copy object * fix sse * fmt * implement sse * sse continue * fixed the suffix range bug (bytes=-N for "last N bytes") * debug logs * Missing PartsCount Header * profiling * url encoding * test_multipart_get_part * headers * debug * adjust log level * handle part number * Update s3api_object_handlers.go * nil safety * set ModifiedTsNs * remove * nil check * fix sse header * same logic as filer * decode values * decode ivBase64 * s3: Fix SSE decryption JWT authentication and streaming errors Critical fix for SSE (Server-Side Encryption) test failures: 1. JWT Authentication Bug (Root Cause): - Changed from GenJwtForFilerServer to GenJwtForVolumeServer - S3 API now uses correct JWT when directly reading from volume servers - Matches filer's authentication pattern for direct volume access - Fixes 'unexpected EOF' and 500 errors in SSE tests 2. Streaming Error Handling: - Added error propagation in getEncryptedStreamFromVolumes goroutine - Use CloseWithError() to properly communicate stream failures - Added debug logging for streaming errors 3. Response Header Timing: - Removed premature WriteHeader(http.StatusOK) call - Let Go's http package write status automatically on first write - Prevents header lock when errors occur during streaming 4. Enhanced SSE Decryption Debugging: - Added IV/Key validation and logging for SSE-C, SSE-KMS, SSE-S3 - Better error messages for missing or invalid encryption metadata - Added glog.V(2) debugging for decryption setup This fixes SSE integration test failures where encrypted objects could not be retrieved due to volume server authentication failures. The JWT bug was causing volume servers to reject requests, resulting in truncated/empty streams (EOF) or internal errors. * s3: Fix SSE multipart upload metadata preservation Critical fix for SSE multipart upload test failures (SSE-C and SSE-KMS): Root Cause - Incomplete SSE Metadata Copying: The old code only tried to copy 'SeaweedFSSSEKMSKey' from the first part to the completed object. This had TWO bugs: 1. Wrong Constant Name (Key Mismatch Bug): - Storage uses: SeaweedFSSSEKMSKeyHeader = 'X-SeaweedFS-SSE-KMS-Key' - Old code read: SeaweedFSSSEKMSKey = 'x-seaweedfs-sse-kms-key' - Result: SSE-KMS metadata was NEVER copied → 500 errors 2. Missing SSE-C and SSE-S3 Headers: - SSE-C requires: IV, Algorithm, KeyMD5 - SSE-S3 requires: encrypted key data + standard headers - Old code: copied nothing for SSE-C/SSE-S3 → decryption failures Fix - Complete SSE Header Preservation: Now copies ALL SSE headers from first part to completed object: - SSE-C: SeaweedFSSSEIV, CustomerAlgorithm, CustomerKeyMD5 - SSE-KMS: SeaweedFSSSEKMSKeyHeader, AwsKmsKeyId, ServerSideEncryption - SSE-S3: SeaweedFSSSES3Key, ServerSideEncryption Applied consistently to all 3 code paths: 1. Versioned buckets (creates version file) 2. Suspended versioning (creates main object with null versionId) 3. Non-versioned buckets (creates main object) Why This Is Correct: The headers copied EXACTLY match what putToFiler stores during part upload (lines 496-521 in s3api_object_handlers_put.go). This ensures detectPrimarySSEType() can correctly identify encrypted multipart objects and trigger inline decryption with proper metadata. Fixes: TestSSEMultipartUploadIntegration (SSE-C and SSE-KMS subtests) * s3: Add debug logging for versioning state diagnosis Temporary debug logging to diagnose test_versioning_obj_plain_null_version_overwrite_suspended failure. Added glog.V(0) logging to show: 1. setBucketVersioningStatus: when versioning status is changed 2. PutObjectHandler: what versioning state is detected (Enabled/Suspended/none) 3. PutObjectHandler: which code path is taken (putVersionedObject vs putSuspendedVersioningObject) This will help identify if: - The versioning status is being set correctly in bucket config - The cache is returning stale/incorrect versioning state - The switch statement is correctly routing to suspended vs enabled handlers * s3: Enhanced versioning state tracing for suspended versioning diagnosis Added comprehensive logging across the entire versioning state flow: PutBucketVersioningHandler: - Log requested status (Enabled/Suspended) - Log when calling setBucketVersioningStatus - Log success/failure of status change setBucketVersioningStatus: - Log bucket and status being set - Log when config is updated - Log completion with error code updateBucketConfig: - Log versioning state being written to cache - Immediate cache verification after Set - Log if cache verification fails getVersioningState: - Log bucket name and state being returned - Log if object lock forces VersioningEnabled - Log errors This will reveal: 1. If PutBucketVersioning(Suspended) is reaching the handler 2. If the cache update succeeds 3. What state getVersioningState returns during PUT 4. Any cache consistency issues Expected to show why bucket still reports 'Enabled' after 'Suspended' call. * s3: Add SSE chunk detection debugging for multipart uploads Added comprehensive logging to diagnose why TestSSEMultipartUploadIntegration fails: detectPrimarySSEType now logs: 1. Total chunk count and extended header count 2. All extended headers with 'sse'/'SSE'/'encryption' in the name 3. For each chunk: index, SseType, and whether it has metadata 4. Final SSE type counts (SSE-C, SSE-KMS, SSE-S3) This will reveal if: - Chunks are missing SSE metadata after multipart completion - Extended headers are copied correctly from first part - The SSE detection logic is working correctly Expected to show if chunks have SseType=0 (none) or proper SSE types set. * s3: Trace SSE chunk metadata through multipart completion and retrieval Added end-to-end logging to track SSE chunk metadata lifecycle: During Multipart Completion (filer_multipart.go): 1. Log finalParts chunks BEFORE mkFile - shows SseType and metadata 2. Log versionEntry.Chunks INSIDE mkFile callback - shows if mkFile preserves SSE info 3. Log success after mkFile completes During GET Retrieval (s3api_object_handlers.go): 1. Log retrieved entry chunks - shows SseType and metadata after retrieval 2. Log detected SSE type result This will reveal at which point SSE chunk metadata is lost: - If finalParts have SSE metadata but versionEntry.Chunks don't → mkFile bug - If versionEntry.Chunks have SSE metadata but retrieved chunks don't → storage/retrieval bug - If chunks never have SSE metadata → multipart completion SSE processing bug Expected to show chunks with SseType=NONE during retrieval even though they were created with proper SseType during multipart completion. * s3: Fix SSE-C multipart IV base64 decoding bug Critical Bug Found: SSE-C multipart uploads were failing because: Root Cause: - entry.Extended[SeaweedFSSSEIV] stores base64-encoded IV (24 bytes for 16-byte IV) - SerializeSSECMetadata expects raw IV bytes (16 bytes) - During multipart completion, we were passing base64 IV directly → serialization error Error Message: "Failed to serialize SSE-C metadata for chunk in part X: invalid IV length: expected 16 bytes, got 24" Fix: - Base64-decode IV before passing to SerializeSSECMetadata - Added error handling for decode failures Impact: - SSE-C multipart uploads will now correctly serialize chunk metadata - Chunks will have proper SSE metadata for decryption during GET This fixes the SSE-C subtest of TestSSEMultipartUploadIntegration. SSE-KMS still has a separate issue (error code 23) being investigated. * fixes * kms sse * handle retry if not found in .versions folder and should read the normal object * quick check (no retries) to see if the .versions/ directory exists * skip retry if object is not found * explicit update to avoid sync delay * fix map update lock * Remove fmt.Printf debug statements * Fix SSE-KMS multipart base IV fallback to fail instead of regenerating * fmt * Fix ACL grants storage logic * header handling * nil handling * range read for sse content * test range requests for sse objects * fmt * unused code * upload in chunks * header case * fix url * bucket policy error vs bucket not found * jwt handling * fmt * jwt in request header * Optimize Case-Insensitive Prefix Check * dead code * Eliminated Unnecessary Stream Prefetch for Multipart SSE * range sse * sse * refactor * context * fmt * fix type * fix SSE-C IV Mismatch * Fix Headers Being Set After WriteHeader * fix url parsing * propergate sse headers * multipart sse-s3 * aws sig v4 authen * sse kms * set content range * better errors * Update s3api_object_handlers_copy.go * Update s3api_object_handlers.go * Update s3api_object_handlers.go * avoid magic number * clean up * Update s3api_bucket_policy_handlers.go * fix url parsing * context * data and metadata both use background context * adjust the offset * SSE Range Request IV Calculation * adjust logs * IV relative to offset in each part, not the whole file * collect logs * offset * fix offset * fix url * logs * variable * jwt * Multipart ETag semantics: conditionally set object-level Md5 for single-chunk uploads only. * sse * adjust IV and offset * multipart boundaries * ensures PUT and GET operations return consistent ETags * Metadata Header Case * CommonPrefixes Sorting with URL Encoding * always sort * remove the extra PathUnescape call * fix the multipart get part ETag * the FileChunk is created without setting ModifiedTsNs * Sort CommonPrefixes lexicographically to match AWS S3 behavior * set md5 for multipart uploads * prevents any potential data loss or corruption in the small-file inline storage path * compiles correctly * decryptedReader will now be properly closed after use * Fixed URL encoding and sort order for CommonPrefixes * Update s3api_object_handlers_list.go * SSE-x Chunk View Decryption * Different IV offset calculations for single-part vs multipart objects * still too verbose in logs * less logs * ensure correct conversion * fix listing * nil check * minor fixes * nil check * single character delimiter * optimize * range on empty object or zero-length * correct IV based on its position within that part, not its position in the entire object * adjust offset * offset Fetch FULL encrypted chunk (not just the range) Adjust IV by PartOffset/ChunkOffset only Decrypt full chunk Skip in the DECRYPTED stream to reach OffsetInChunk * look breaking * refactor * error on no content * handle intra-block byte skipping * Incomplete HTTP Response Error Handling * multipart SSE * Update s3api_object_handlers.go * address comments * less logs * handling directory * Optimized rejectDirectoryObjectWithoutSlash() to avoid unnecessary lookups * Revert "handling directory" This reverts commit `3a335f0ac3`. * constant * Consolidate nil entry checks in GetObjectHandler * add range tests * Consolidate redundant nil entry checks in HeadObjectHandler * adjust logs * SSE type * large files * large files Reverted the plain-object range test * ErrNoEncryptionConfig * Fixed SSERangeReader Infinite Loop Vulnerability * Fixed SSE-KMS Multipart ChunkReader HTTP Body Leak * handle empty directory in S3, added PyArrow tests * purge unused code * Update s3_parquet_test.py * Update requirements.txt * According to S3 specifications, when both partNumber and Range are present, the Range should apply within the selected part's boundaries, not to the full object. * handle errors * errors after writing header * https * fix: Wait for volume assignment readiness before running Parquet tests The test-implicit-dir-with-server test was failing with an Internal Error because volume assignment was not ready when tests started. This fix adds a check that attempts a volume assignment and waits for it to succeed before proceeding with tests. This ensures that: 1. Volume servers are registered with the master 2. Volume growth is triggered if needed 3. The system can successfully assign volumes for writes Fixes the timeout issue where boto3 would retry 4 times and fail with 'We encountered an internal error, please try again.' * sse tests * store derived IV * fix: Clean up gRPC ports between tests to prevent port conflicts The second test (test-implicit-dir-with-server) was failing because the volume server's gRPC port (18080 = VOLUME_PORT + 10000) was still in use from the first test. The cleanup code only killed HTTP port processes, not gRPC port processes. Added cleanup for gRPC ports in all stop targets: - Master gRPC: MASTER_PORT + 10000 (19333) - Volume gRPC: VOLUME_PORT + 10000 (18080) - Filer gRPC: FILER_PORT + 10000 (18888) This ensures clean state between test runs in CI. * add import * address comments * docs: Add placeholder documentation files for Parquet test suite Added three missing documentation files referenced in test/s3/parquet/README.md: 1.

Refactor: Replace removeDuplicateSlashes with NormalizeObjectKey (#7873 )

* Replace removeDuplicateSlashes with NormalizeObjectKey

Use s3_constants.NormalizeObjectKey instead of removeDuplicateSlashes in most places
for consistency. NormalizeObjectKey handles both duplicate slash removal and ensures
the path starts with '/', providing more complete normalization.

* Fix double slash issues after NormalizeObjectKey

After using NormalizeObjectKey, object keys have a leading '/'. This commit ensures:
- getVersionedObjectDir strips leading slash before concatenation
- getEntry calls receive names without leading slash
- String concatenation with '/' doesn't create '//' paths

This prevents path construction errors like:
/buckets/bucket//object (wrong)
/buckets/bucket/object (correct)

* ensure object key leading "/"

* fix compilation

* fix: Strip leading slash from object keys in S3 API responses

After introducing NormalizeObjectKey, all internal object keys have a
leading slash. However, S3 API responses must return keys without
leading slashes to match AWS S3 behavior.

Fixed in three functions:
- addVersion: Strip slash for version list entries
- processRegularFile: Strip slash for regular file entries
- processExplicitDirectory: Strip slash for directory entries

This ensures ListObjectVersions and similar APIs return keys like
'bar' instead of '/bar', matching S3 API specifications.

* fix: Normalize keyMarker for consistent pagination comparison

The S3 API provides keyMarker without a leading slash (e.g., 'object-001'),
but after introducing NormalizeObjectKey, all internal object keys have
leading slashes (e.g., '/object-001').

When comparing keyMarker < normalizedObjectKey in shouldSkipObjectForMarker,
the ASCII value of '/' (47) is less than 'o' (111), causing all objects
to be incorrectly skipped during pagination. This resulted in page 2 and
beyond returning 0 results.

Fix: Normalize the keyMarker when creating versionCollector so comparisons
work correctly with normalized object keys.

Fixes pagination tests:
- TestVersioningPaginationOver1000Versions
- TestVersioningPaginationMultipleObjectsManyVersions

* refactor: Change NormalizeObjectKey to return keys without leading slash

BREAKING STRATEGY CHANGE:
Previously, NormalizeObjectKey added a leading slash to all object keys,
which required stripping it when returning keys to S3 API clients and
caused complexity in marker normalization for pagination.

NEW STRATEGY:
- NormalizeObjectKey now returns keys WITHOUT leading slash (e.g., 'foo/bar' not '/foo/bar')
- This matches the S3 API format directly
- All path concatenations now explicitly add '/' between bucket and object
- No need to strip slashes in responses or normalize markers

Changes:
1. Modified NormalizeObjectKey to strip leading slash instead of adding it
2. Fixed all path concatenations to use:
- BucketsPath + '/' + bucket + '/' + object
instead of:
- BucketsPath + '/' + bucket + object
3. Reverted response key stripping in:
- addVersion()
- processRegularFile()
- processExplicitDirectory()
4. Reverted keyMarker normalization in findVersionsRecursively()
5. Updated matchesPrefixFilter() to work with keys without leading slash
6. Fixed paths in handlers:
- s3api_object_handlers.go (GetObject, HeadObject, cacheRemoteObjectForStreaming)
- s3api_object_handlers_postpolicy.go
- s3api_object_handlers_tagging.go
- s3api_object_handlers_acl.go
- s3api_version_id.go (getVersionedObjectDir, getVersionIdFormat)
- s3api_object_versioning.go (getObjectVersionList, updateLatestVersionAfterDeletion)

All versioning tests pass including pagination stress tests.

* adjust format

* Update post policy tests to match new NormalizeObjectKey behavior

- Update TestPostPolicyKeyNormalization to expect keys without leading slashes
- Update TestNormalizeObjectKey to expect keys without leading slashes
- Update TestPostPolicyFilenameSubstitution to expect keys without leading slashes
- Update path construction in tests to use new pattern: BucketsPath + '/' + bucket + '/' + object

* Fix ListObjectVersions prefix filtering

Remove leading slash addition to prefix parameter to allow correct filtering
of .versions directories when listing object versions with a specific prefix.

The prefix parameter should match entry paths relative to bucket root.
Adding a leading slash was breaking the prefix filter for paginated requests.

Fixes pagination issue where second page returned 0 versions instead of
continuing with remaining versions.

* no leading slash

* Fix urlEscapeObject to add leading slash for filer paths

NormalizeObjectKey now returns keys without leading slashes to match S3 API format.
However, urlEscapeObject is used for filer paths which require leading slashes.
Add leading slash back after normalization to ensure filer paths are correct.

Fixes TestS3ApiServer_toFilerPath test failures.

* adjust tests

* normalize

* Fix: Normalize prefixes and markers in LIST operations using NormalizeObjectKey

Ensure consistent key normalization across all S3 operations (GET, PUT, LIST).
Previously, LIST operations were not applying the same normalization rules
(handling backslashes, duplicate slashes, leading slashes) as GET/PUT operations.

Changes:
- Updated normalizePrefixMarker() to call NormalizeObjectKey for both prefix and marker
- This ensures prefixes with leading slashes, backslashes, or duplicate slashes are
handled consistently with how object keys are normalized
- Fixes Parquet test failures where pads.write_dataset creates implicit directory
structures that couldn't be discovered by subsequent LIST operations
- Added TestPrefixNormalizationInList and TestListPrefixConsistency tests

All existing LIST tests continue to pass with the normalization improvements.

* Add debugging logging to LIST operations to track prefix normalization

* Fix: Remove leading slash addition from GetPrefix to work with NormalizeObjectKey

The NormalizeObjectKey function removes leading slashes to match S3 API format
(e.g., 'foo/bar' not '/foo/bar'). However, GetPrefix was adding a leading slash
back, which caused LIST operations to fail with incorrect path handling.

Now GetPrefix only normalizes duplicate slashes without adding a leading slash,
which allows NormalizeObjectKey changes to work correctly for S3 LIST operations.

All Parquet integration tests now pass (20/20).

* Fix: Handle object paths without leading slash in checkDirectoryObject

NormalizeObjectKey() removes the leading slash to match S3 API format.
However, checkDirectoryObject() was assuming the object path has a leading
slash when processing directory markers (paths ending with '/').

Now we ensure the object has a leading slash before processing it for
filer operations.

Fixes implicit directory marker test (explicit_dir/) while keeping
Parquet integration tests passing (20/20).

All tests pass:
- Implicit directory tests: 6/6
- Parquet integration tests: 20/20

* Fix: Handle explicit directory markers with trailing slashes

Explicit directory markers created with put_object(Key='dir/', ...) are stored
in the filer with the trailing slash as part of the name. The checkDirectoryObject()
function now checks for both:
1. Explicit directories: lookup with trailing slash preserved (e.g., 'explicit_dir/')
2. Implicit directories: lookup without trailing slash (e.g., 'implicit_dir')

This ensures both types of directory markers are properly recognized.

All tests pass:
- Implicit directory tests: 6/6 (including explicit directory marker test)
- Parquet integration tests: 20/20

* Fix: Preserve trailing slash in NormalizeObjectKey

NormalizeObjectKey now preserves trailing slashes when normalizing object keys.
This is important for explicit directory markers like 'explicit_dir/' which rely
on the trailing slash to be recognized as directory objects.

The normalization process:
1. Notes if trailing slash was present
2. Removes duplicate slashes and converts backslashes
3. Removes leading slash for S3 API format
4. Restores trailing slash if it was in the original

This ensures explicit directory markers created with put_object(Key='dir/', ...)
are properly normalized and can be looked up by their exact name.

All tests pass:
- Implicit directory tests: 6/6
- Parquet integration tests: 20/20

* clean object

* Fix: Don't restore trailing slash if result is empty

When normalizing paths that are only slashes (e.g., '///', '/'), the function
should return an empty string, not a single slash. The fix ensures we only
restore the trailing slash if the result is non-empty.

This fixes the 'just_slashes' test case:
- Input: '///'
- Expected: ''
- Previous: '/'
- Fixed: ''

All tests now pass:
- Unit tests: TestNormalizeObjectKey (13/13)
- Implicit directory tests: 6/6

* s3: Fix SSE decryption JWT authentication and streaming errors

Critical fix for SSE (Server-Side Encryption) test failures:

1. **JWT Authentication Bug** (Root Cause):
   - Changed from GenJwtForFilerServer to GenJwtForVolumeServer
   - S3 API now uses correct JWT when directly reading from volume servers
   - Matches filer's authentication pattern for direct volume access
   - Fixes 'unexpected EOF' and 500 errors in SSE tests

2. **Streaming Error Handling**:
   - Added error propagation in getEncryptedStreamFromVolumes goroutine
   - Use CloseWithError() to properly communicate stream failures
   - Added debug logging for streaming errors

3. **Response Header Timing**:
   - Removed premature WriteHeader(http.StatusOK) call
   - Let Go's http package write status automatically on first write
   - Prevents header lock when errors occur during streaming

4. **Enhanced SSE Decryption Debugging**:
   - Added IV/Key validation and logging for SSE-C, SSE-KMS, SSE-S3
   - Better error messages for missing or invalid encryption metadata
   - Added glog.V(2) debugging for decryption setup

This fixes SSE integration test failures where encrypted objects
could not be retrieved due to volume server authentication failures.
The JWT bug was causing volume servers to reject requests, resulting
in truncated/empty streams (EOF) or internal errors.

* s3: Fix SSE multipart upload metadata preservation

Critical fix for SSE multipart upload test failures (SSE-C and SSE-KMS):

**Root Cause - Incomplete SSE Metadata Copying**:
The old code only tried to copy 'SeaweedFSSSEKMSKey' from the first
part to the completed object. This had TWO bugs:

1. **Wrong Constant Name** (Key Mismatch Bug):
   - Storage uses: SeaweedFSSSEKMSKeyHeader = 'X-SeaweedFS-SSE-KMS-Key'
   - Old code read: SeaweedFSSSEKMSKey = 'x-seaweedfs-sse-kms-key'
   - Result: SSE-KMS metadata was NEVER copied → 500 errors

2. **Missing SSE-C and SSE-S3 Headers**:
   - SSE-C requires: IV, Algorithm, KeyMD5
   - SSE-S3 requires: encrypted key data + standard headers
   - Old code: copied nothing for SSE-C/SSE-S3 → decryption failures

**Fix - Complete SSE Header Preservation**:
Now copies ALL SSE headers from first part to completed object:

- SSE-C: SeaweedFSSSEIV, CustomerAlgorithm, CustomerKeyMD5
- SSE-KMS: SeaweedFSSSEKMSKeyHeader, AwsKmsKeyId, ServerSideEncryption
- SSE-S3: SeaweedFSSSES3Key, ServerSideEncryption

Applied consistently to all 3 code paths:
1. Versioned buckets (creates version file)
2. Suspended versioning (creates main object with null versionId)
3. Non-versioned buckets (creates main object)

**Why This Is Correct**:
The headers copied EXACTLY match what putToFiler stores during part
upload (lines 496-521 in s3api_object_handlers_put.go). This ensures
detectPrimarySSEType() can correctly identify encrypted multipart
objects and trigger inline decryption with proper metadata.

Fixes: TestSSEMultipartUploadIntegration (SSE-C and SSE-KMS subtests)

* s3: Add debug logging for versioning state diagnosis

Temporary debug logging to diagnose test_versioning_obj_plain_null_version_overwrite_suspended failure.

Added glog.V(0) logging to show:
1. setBucketVersioningStatus: when versioning status is changed
2. PutObjectHandler: what versioning state is detected (Enabled/Suspended/none)
3. PutObjectHandler: which code path is taken (putVersionedObject vs putSuspendedVersioningObject)

This will help identify if:
- The versioning status is being set correctly in bucket config
- The cache is returning stale/incorrect versioning state
- The switch statement is correctly routing to suspended vs enabled handlers

* s3: Enhanced versioning state tracing for suspended versioning diagnosis

Added comprehensive logging across the entire versioning state flow:

PutBucketVersioningHandler:
- Log requested status (Enabled/Suspended)
- Log when calling setBucketVersioningStatus
- Log success/failure of status change

setBucketVersioningStatus:
- Log bucket and status being set
- Log when config is updated
- Log completion with error code

updateBucketConfig:
- Log versioning state being written to cache
- Immediate cache verification after Set
- Log if cache verification fails

getVersioningState:
- Log bucket name and state being returned
- Log if object lock forces VersioningEnabled
- Log errors

This will reveal:
1. If PutBucketVersioning(Suspended) is reaching the handler
2. If the cache update succeeds
3. What state getVersioningState returns during PUT
4. Any cache consistency issues

Expected to show why bucket still reports 'Enabled' after 'Suspended' call.

* s3: Add SSE chunk detection debugging for multipart uploads

Added comprehensive logging to diagnose why TestSSEMultipartUploadIntegration fails:

detectPrimarySSEType now logs:
1. Total chunk count and extended header count
2. All extended headers with 'sse'/'SSE'/'encryption' in the name
3. For each chunk: index, SseType, and whether it has metadata
4. Final SSE type counts (SSE-C, SSE-KMS, SSE-S3)

This will reveal if:
- Chunks are missing SSE metadata after multipart completion
- Extended headers are copied correctly from first part
- The SSE detection logic is working correctly

Expected to show if chunks have SseType=0 (none) or proper SSE types set.

* s3: Trace SSE chunk metadata through multipart completion and retrieval

Added end-to-end logging to track SSE chunk metadata lifecycle:

**During Multipart Completion (filer_multipart.go)**:
1. Log finalParts chunks BEFORE mkFile - shows SseType and metadata
2. Log versionEntry.Chunks INSIDE mkFile callback - shows if mkFile preserves SSE info
3. Log success after mkFile completes

**During GET Retrieval (s3api_object_handlers.go)**:
1. Log retrieved entry chunks - shows SseType and metadata after retrieval
2. Log detected SSE type result

This will reveal at which point SSE chunk metadata is lost:
- If finalParts have SSE metadata but versionEntry.Chunks don't → mkFile bug
- If versionEntry.Chunks have SSE metadata but retrieved chunks don't → storage/retrieval bug
- If chunks never have SSE metadata → multipart completion SSE processing bug

Expected to show chunks with SseType=NONE during retrieval even though
they were created with proper SseType during multipart completion.

* s3: Fix SSE-C multipart IV base64 decoding bug

**Critical Bug Found**: SSE-C multipart uploads were failing because:

Root Cause:
- entry.Extended[SeaweedFSSSEIV] stores base64-encoded IV (24 bytes for 16-byte IV)
- SerializeSSECMetadata expects raw IV bytes (16 bytes)
- During multipart completion, we were passing base64 IV directly → serialization error

Error Message:
"Failed to serialize SSE-C metadata for chunk in part X: invalid IV length: expected 16 bytes, got 24"

Fix:
- Base64-decode IV before passing to SerializeSSECMetadata
- Added error handling for decode failures

Impact:
- SSE-C multipart uploads will now correctly serialize chunk metadata
- Chunks will have proper SSE metadata for decryption during GET

This fixes the SSE-C subtest of TestSSEMultipartUploadIntegration.
SSE-KMS still has a separate issue (error code 23) being investigated.

* fix: Wait for volume assignment readiness before running Parquet tests

The test-implicit-dir-with-server test was failing with an Internal Error
because volume assignment was not ready when tests started. This fix adds
a check that attempts a volume assignment and waits for it to succeed
before proceeding with tests.

This ensures that:
1. Volume servers are registered with the master
2. Volume growth is triggered if needed
3. The system can successfully assign volumes for writes

Fixes the timeout issue where boto3 would retry 4 times and fail with
'We encountered an internal error, please try again.'

* sse tests

* store derived IV

* fix: Clean up gRPC ports between tests to prevent port conflicts

The second test (test-implicit-dir-with-server) was failing because the
volume server's gRPC port (18080 = VOLUME_PORT + 10000) was still in use
from the first test. The cleanup code only killed HTTP port processes,
not gRPC port processes.

Added cleanup for gRPC ports in all stop targets:
- Master gRPC: MASTER_PORT + 10000 (19333)
- Volume gRPC: VOLUME_PORT + 10000 (18080)
- Filer gRPC: FILER_PORT + 10000 (18888)

This ensures clean state between test runs in CI.

* add import

* address comments

* docs: Add placeholder documentation files for Parquet test suite

Added three missing documentation files referenced in test/s3/parquet/README.md:

1. TEST_COVERAGE.md - Documents 43 total test cases (17 Go unit tests,
   6 Python integration tests, 20 Python end-to-end tests)

2. FINAL_ROOT_CAUSE_ANALYSIS.md - Explains the s3fs compatibility issue
   with PyArrow, the implicit directory problem, and how the fix works

3. MINIO_DIRECTORY_HANDLING.md - Compares MinIO's directory handling
   approach with SeaweedFS's implementation

Each file contains:
- Title and overview
- Key technical details relevant to the topic
- TODO sections for future expansion

These placeholder files resolve the broken README links and provide
structure for future detailed documentation.
