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. 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. * clean up if metadata operation failed * Update s3_parquet_test.py * clean up * Update Makefile * Update s3_parquet_test.py * Update Makefile * Handle ivSkip for non-block-aligned offsets * Update README.md * stop volume server faster * stop volume server in 1 second * different IV for each chunk in SSE-S3 and SSE-KMS * clean up if fails * testing upload * error propagation * fmt * simplify * fix copying * less logs * endian * Added marshaling error handling * handling invalid ranges * error handling for adding to log buffer * fix logging * avoid returning too quickly and ensure proper cleaning up * Activity Tracking for Disk Reads * Cleanup Unused Parameters * Activity Tracking for Kafka Publishers * Proper Test Error Reporting * refactoring * less logs * less logs * go fmt * guard it with if entry.Attributes.TtlSec > 0 to match the pattern used elsewhere. * Handle bucket-default encryption config errors explicitly for multipart * consistent activity tracking * obsolete code for s3 on filer read/write handlers * Update weed/s3api/s3api_object_handlers_list.go Co-authored-by: gemini-code-assist[bot] <176961590+gemini-code-assist[bot]@users.noreply.github.com> --------- Co-authored-by: gemini-code-assist[bot] <176961590+gemini-code-assist[bot]@users.noreply.github.com>	4 months ago

Add table operations test (#8241 )

* Add Trino blog operations test

* Update test/s3tables/catalog_trino/trino_blog_operations_test.go

Co-authored-by: gemini-code-assist[bot] <176961590+gemini-code-assist[bot]@users.noreply.github.com>

* feat: add table bucket path helpers and filer operations

- Add table object root and table location mapping directories

- Clean up table object bucket paths on deletion
- Enable S3 operations on table bucket object roots

* feat: add table location mapping for Iceberg REST

- Track table location bucket mappings when tables are created/updated/deleted
- Enable location-based routing for S3 operations on table data

* feat: route S3 operations to table bucket object roots

- Route table-s3 bucket names to mapped table paths
- Route table buckets to object root directories
- Support table location bucket mapping lookup

* feat: emit table-s3 locations from Iceberg REST

- Generate unique table-s3 bucket names with UUID suffix
- Store table metadata under table bucket paths
- Return table-s3 locations for Trino compatibility

* fix: handle missing directories in S3 list operations

- Propagate ErrNotFound from ListEntries for non-existent directories
- Treat missing directories as empty results for list operations
- Fixes Trino non-empty location checks on table creation

* test: improve Trino CSV parsing for single-value results

- Sanitize Trino output to skip jline warnings
- Handle single-value CSV results without header rows
- Strip quotes from numeric values in tests

* refactor: use bucket path helpers throughout S3 API

- Replace direct bucket path operations with helper functions
- Leverage centralized table bucket routing logic
- Improve maintainability with consistent path resolution

* fix: add table bucket cache and improve filer error handling

- Cache table bucket lookups to reduce filer overhead on repeated checks
- Use filer_pb.CreateEntry and filer_pb.UpdateEntry helpers to check resp.Error
- Fix delete order in handler_bucket_get_list_delete: delete table object before directory
- Make location mapping errors best-effort: log and continue, don't fail API
- Update table location mappings to delete stale prior bucket mappings on update
- Add 1-second sleep before timestamp time travel query to ensure timestamps are in past
- Fix CSV parsing: examine all lines, not skip first; handle single-value rows

* fix: properly handle stale metadata location mapping cleanup

- Capture oldMetadataLocation before mutation in handleUpdateTable
- Update updateTableLocationMapping to accept both old and new locations
- Use passed-in oldMetadataLocation to detect location changes
- Delete stale mapping only when location actually changes
- Pass empty string for oldLocation in handleCreateTable (new tables have no prior mapping)
- Improve logging to show old -> new location transitions

* refactor: cleanup imports and cache design

- Remove unused 'sync' import from bucket_paths.go
- Use filer_pb.UpdateEntry helper in setExtendedAttribute and deleteExtendedAttribute for consistent error handling
- Add dedicated tableBucketCache map[string]bool to BucketRegistry instead of mixing concerns with metadataCache
- Improve cache separation: table buckets cache is now separate from bucket metadata cache

* fix: improve cache invalidation and add transient error handling

Cache invalidation (critical fix):
- Add tableLocationCache to BucketRegistry for location mapping lookups
- Clear tableBucketCache and tableLocationCache in RemoveBucketMetadata
- Prevents stale cache entries when buckets are deleted/recreated

Transient error handling:
- Only cache table bucket lookups when conclusive (found or ErrNotFound)
- Skip caching on transient errors (network, permission, etc)
- Prevents marking real table buckets as non-table due to transient failures

Performance optimization:
- Cache tableLocationDir results to avoid repeated filer RPCs on hot paths
- tableLocationDir now checks cache before making expensive filer lookups
- Cache stores empty string for 'not found' to avoid redundant lookups

Code clarity:
- Add comment to deleteDirectory explaining DeleteEntry response lacks Error field

* go fmt

* fix: mirror transient error handling in tableLocationDir and optimize bucketDir

Transient error handling:
- tableLocationDir now only caches definitive results
- Mirrors isTableBucket behavior to prevent treating transient errors as permanent misses
- Improves reliability on flaky systems or during recovery

Performance optimization:
- bucketDir avoids redundant isTableBucket call via bucketRoot
- Directly use s3a.option.BucketsPath for regular buckets
- Saves one cache lookup for every non-table bucket operation

* fix: revert bucketDir optimization to preserve bucketRoot logic

The optimization to directly use BucketsPath bypassed bucketRoot's logic
and caused issues with S3 list operations on delimiter+prefix cases.

Revert to using path.Join(s3a.bucketRoot(bucket), bucket) which properly
handles all bucket types and ensures consistent path resolution across
the codebase.

The slight performance cost of an extra cache lookup is worth the correctness
and consistency benefits.

* feat: move table buckets under /buckets

Add a table-bucket marker attribute, reuse bucket metadata cache for table bucket detection, and update list/validation/UI/test paths to treat table buckets as /buckets entries.

* Fix S3 Tables code review issues

- handler_bucket_create.go: Fix bucket existence check to properly validate
  entryResp.Entry before setting s3BucketExists flag (nil Entry should not
  indicate existing bucket)
- bucket_paths.go: Add clarifying comment to bucketRoot() explaining unified
  buckets root path for all bucket types
- file_browser_data.go: Optimize by extracting table bucket check early to
  avoid redundant WithFilerClient call

* Fix list prefix delimiter handling

* Handle list errors conservatively

* Fix Trino FOR TIMESTAMP query - use past timestamp

Iceberg requires the timestamp to be strictly in the past.
Use current_timestamp - interval '1' second instead of current_timestamp.

* 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.

* 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.
