Chris Lu	ee3813787e	feat(s3api): Implement S3 Policy Variables (#8039 ) * feat: Add AWS IAM Policy Variables support to S3 API Implements policy variables for dynamic access control in bucket policies. Supported variables: - aws:username - Extracted from principal ARN - aws:userid - User identifier (same as username in SeaweedFS) - aws:principaltype - IAMUser, IAMRole, or AssumedRole - jwt:* - Any JWT claim (e.g., jwt:preferred_username, jwt:sub) Key changes: - Added PolicyVariableRegex to detect ${...} patterns - Extended CompiledStatement with DynamicResourcePatterns, DynamicPrincipalPatterns, DynamicActionPatterns - Added Claims field to PolicyEvaluationArgs for JWT claim access - Implemented SubstituteVariables() for variable replacement from context and JWT claims - Implemented extractPrincipalVariables() for ARN parsing - Updated EvaluateConditions() to support variable substitution - Comprehensive unit and integration tests Resolves #8037 * feat: Add LDAP and PrincipalAccount variable support Completes future enhancements for policy variables: - Added ldap:* variable support for LDAP claims - ldap:username - LDAP username from claims - ldap:dn - LDAP distinguished name from claims - ldap:* - Any LDAP claim - Added aws:PrincipalAccount extraction from ARN - Extracts account ID from principal ARN - Available as ${aws:PrincipalAccount} in policies Updated SubstituteVariables() to check LDAP claims Updated extractPrincipalVariables() to extract account ID Added comprehensive tests for new variables * feat(s3api): implement IAM policy variables core logic and optimization * feat(s3api): integrate policy variables with S3 authentication and handlers * test(s3api): add integration tests for policy variables * cleanup: remove unused policy conversion files * Add S3 policy variables integration tests and path support - Add comprehensive integration tests for policy variables - Test username isolation, JWT claims, LDAP claims - Add support for IAM paths in principal ARN parsing - Add tests for principals with paths * Fix IAM Role principal variable extraction IAM Roles should not have aws:userid or aws:PrincipalAccount according to AWS behavior. Only IAM Users and Assumed Roles should have these variables. Fixes TestExtractPrincipalVariables test failures. * Security fixes and bug fixes for S3 policy variables SECURITY FIXES: - Prevent X-SeaweedFS-Principal header spoofing by clearing internal headers at start of authentication (auth_credentials.go) - Restrict policy variable substitution to safe allowlist to prevent client header injection (iam/policy/policy_engine.go) - Add core policy validation before storing bucket policies BUG FIXES: - Remove unused sid variable in evaluateStatement - Fix LDAP claim lookup to check both prefixed and unprefixed keys - Add ValidatePolicy call in PutBucketPolicyHandler These fixes prevent privilege escalation via header injection and ensure only validated identity claims are used in policy evaluation. * Additional security fixes and code cleanup SECURITY FIXES: - Fixed X-Forwarded-For spoofing by only trusting proxy headers from private/localhost IPs (s3_iam_middleware.go) - Changed context key from "sourceIP" to "aws:SourceIp" for proper policy variable substitution CODE IMPROVEMENTS: - Kept aws:PrincipalAccount for IAM Roles to support condition evaluations - Removed redundant STS principaltype override - Removed unused service variable - Cleaned up commented-out debug logging statements - Updated tests to reflect new IAM Role behavior These changes prevent IP spoofing attacks and ensure policy variables work correctly with the safe allowlist. * Add security documentation for ParseJWTToken Added comprehensive security comments explaining that ParseJWTToken is safe despite parsing without verification because: - It's only used for routing to the correct verification method - All code paths perform cryptographic verification before trusting claims - OIDC tokens: validated via validateExternalOIDCToken - STS tokens: validated via ValidateSessionToken Enhanced function documentation with clear security warnings about proper usage to prevent future misuse. * Fix IP condition evaluation to use aws:SourceIp key Fixed evaluateIPCondition in IAM policy engine to use "aws:SourceIp" instead of "sourceIP" to match the updated extractRequestContext. This fixes the failing IP-restricted role test where IP-based policy conditions were not being evaluated correctly. Updated all test cases to use the correct "aws:SourceIp" key. * Address code review feedback: optimize and clarify PERFORMANCE IMPROVEMENT: - Optimized expandPolicyVariables to use regexp.ReplaceAllStringFunc for single-pass variable substitution instead of iterating through all safe variables. This improves performance from O(nm) to O(m) where n is the number of safe variables and m is the pattern length. CODE CLARITY: - Added detailed comment explaining LDAP claim fallback mechanism (checks both prefixed and unprefixed keys for compatibility) - Enhanced TODO comment for trusted proxy configuration with rationale and recommendations for supporting cloud load balancers, CDNs, and complex network topologies All tests passing. Address Copilot code review feedback BUG FIXES: - Fixed type switch for int/int32/int64 - separated into individual cases since interface type switches only match the first type in multi-type cases - Fixed grammatically incorrect error message in types.go CODE QUALITY: - Removed duplicate Resource/NotResource validation (already in ValidateStatement) - Added comprehensive comment explaining isEnabled() logic and security implications - Improved trusted proxy NOTE comment to be more concise while noting limitations All tests passing. * Fix test failures after extractSourceIP security changes Updated tests to work with the security fix that only trusts X-Forwarded-For/X-Real-IP headers from private IP addresses: - Set RemoteAddr to 127.0.0.1 in tests to simulate trusted proxy - Changed context key from "sourceIP" to "aws:SourceIp" - Added test case for untrusted proxy (public RemoteAddr) - Removed invalid ValidateStatement call (validation happens in ValidatePolicy) All tests now passing. * Address remaining Gemini code review feedback CODE SAFETY: - Deep clone Action field in CompileStatement to prevent potential data races if the original policy document is modified after compilation TEST CLEANUP: - Remove debug logging (fmt.Fprintf) from engine_notresource_test.go - Remove unused imports in engine_notresource_test.go All tests passing. * Fix insecure JWT parsing in IAM auth flow SECURITY FIX: - Renamed ParseJWTToken to ParseUnverifiedJWTToken with explicit security warnings. - Refactored AuthenticateJWT to use the trusted SessionInfo returned by ValidateSessionToken instead of relying on unverified claims from the initial parse. - Refactored ValidatePresignedURLWithIAM to reuse the robust AuthenticateJWT logic, removing duplicated and insecure manual token parsing. This ensures all identity information (Role, Principal, Subject) used for authorization decisions is derived solely from cryptographically verified tokens. * Security: Fix insecure JWT claim extraction in policy engine - Refactored EvaluatePolicy to accept trusted claims from verified Identity instead of parsing unverified tokens - Updated AuthenticateJWT to populate Claims in IAMIdentity from verified sources (SessionInfo/ExternalIdentity) - Updated s3api_server and handlers to pass claims correctly - Improved isPrivateIP to support IPv6 loopback, link-local, and ULA - Fixed flaky distributed_session_consistency test with retry logic * fix(iam): populate Subject in STSSessionInfo to ensure correct identity propagation This fixes the TestS3IAMAuthentication/valid_jwt_token_authentication failure by ensuring the session subject (sub) is correctly mapped to the internal SessionInfo struct, allowing bucket ownership validation to succeed. * Optimized isPrivateIP * Create s3-policy-tests.yml * fix tests * fix tests * tests(s3/iam): simplify policy to resource-based \ (step 1) * tests(s3/iam): add explicit Deny NotResource for isolation (step 2) * fixes * policy: skip resource matching for STS trust policies to allow AssumeRole evaluation * refactor: remove debug logging and hoist policy variables for performance * test: fix TestS3IAMBucketPolicyIntegration cleanup to handle per-subtest object lifecycle * test: fix bucket name generation to comply with S3 63-char limit * test: skip TestS3IAMPolicyEnforcement until role setup is implemented * test: use weed mini for simpler test server deployment Replace 'weed server' with 'weed mini' for IAM tests to avoid port binding issues and simplify the all-in-one server deployment. This improves test reliability and execution time. * security: prevent allocation overflow in policy evaluation Add maxPoliciesForEvaluation constant to cap the number of policies evaluated in a single request. This prevents potential integer overflow when allocating slices for policy lists that may be influenced by untrusted input. Changes: - Add const maxPoliciesForEvaluation = 1024 to set an upper bound - Validate len(policies) < maxPoliciesForEvaluation before appending bucket policy - Use append() instead of make([]string, len+1) to avoid arithmetic overflow - Apply fix to both IsActionAllowed policy evaluation paths	3 weeks ago
Chris Lu	d6d893c8c3	s3: add s3:ExistingObjectTag condition support for bucket policies (#7677 ) * s3: add s3:ExistingObjectTag condition support in policy engine Add support for s3:ExistingObjectTag/<tag-key> condition keys in bucket policies, allowing access control based on object tags. Changes: - Add ObjectEntry field to PolicyEvaluationArgs (entry.Extended metadata) - Update EvaluateConditions to handle s3:ExistingObjectTag/<key> format - Extract tag value from entry metadata using X-Amz-Tagging-<key> prefix This enables policies like: { "Condition": { "StringEquals": { "s3:ExistingObjectTag/status": ["public"] } } } Fixes: https://github.com/seaweedfs/seaweedfs/issues/7447 * s3: update EvaluatePolicy to accept object entry for tag conditions Update BucketPolicyEngine.EvaluatePolicy to accept objectEntry parameter (entry.Extended metadata) for evaluating tag-based policy conditions. Changes: - Add objectEntry parameter to EvaluatePolicy method - Update callers in auth_credentials.go and s3api_bucket_handlers.go - Pass nil for objectEntry in auth layer (entry fetched later in handlers) For tag-based conditions to work, handlers should call EvaluatePolicy with the object's entry.Extended after fetching the entry from filer. * s3: add tests for s3:ExistingObjectTag policy conditions Add comprehensive tests for object tag-based policy conditions: - TestExistingObjectTagCondition: Basic tag matching scenarios - Matching/non-matching tag values - Missing tags, no tags, empty tags - Multiple tags with one matching - TestExistingObjectTagConditionMultipleTags: Multiple tag conditions - Both tags match - Only one tag matches - TestExistingObjectTagDenyPolicy: Deny policies with tag conditions - Default allow without tag - Deny when specific tag present * s3: document s3:ExistingObjectTag support and feature status Update policy engine documentation: - Add s3:ExistingObjectTag/<tag-key> to supported condition keys - Add 'Object Tag-Based Access Control' section with examples - Add 'Feature Status' section with implemented and planned features Planned features for future implementation: - s3:RequestObjectTag/<key> - s3:RequestObjectTagKeys - s3:x-amz-server-side-encryption - Cross-account access * Implement tag-based policy re-check in handlers - Add checkPolicyWithEntry helper to S3ApiServer for handlers to re-check policy after fetching object entry (for s3:ExistingObjectTag conditions) - Add HasPolicyForBucket method to policy engine for efficient check - Integrate policy re-check in GetObjectHandler after entry is fetched - Integrate policy re-check in HeadObjectHandler after entry is fetched - Update auth_credentials.go comments to explain two-phase evaluation - Update documentation with supported operations for tag-based conditions This implements 'Approach 1' where handlers re-check the policy with the object entry after fetching it, allowing tag-based conditions to be properly evaluated. * Add integration tests for s3:ExistingObjectTag conditions - Add TestCheckPolicyWithEntry: tests checkPolicyWithEntry helper with various tag scenarios (matching tags, non-matching tags, empty entry, nil entry) - Add TestCheckPolicyWithEntryNoPolicyForBucket: tests early return when no policy - Add TestCheckPolicyWithEntryNilPolicyEngine: tests nil engine handling - Add TestCheckPolicyWithEntryDenyPolicy: tests deny policies with tag conditions - Add TestHasPolicyForBucket: tests HasPolicyForBucket method These tests cover the Phase 2 policy evaluation with object entry metadata, ensuring tag-based conditions are properly evaluated. * Address code review nitpicks - Remove unused extractObjectTags placeholder function (engine.go) - Add clarifying comment about s3:ExistingObjectTag/<key> evaluation - Consolidate duplicate tag-based examples in README - Factor out tagsToEntry helper to package level in tests * Address code review feedback - Fix unsafe type assertions in GetObjectHandler and HeadObjectHandler when getting identity from context (properly handle type assertion failure) - Extract getConditionContextValue helper to eliminate duplicated logic between EvaluateConditions and EvaluateConditionsLegacy - Ensure consistent handling of missing condition keys (always return empty slice) * Fix GetObjectHandler to match HeadObjectHandler pattern Add safety check for nil objectEntryForSSE before tag-based policy evaluation, ensuring tag-based conditions are always evaluated rather than silently skipped if entry is unexpectedly nil. Addresses review comment from Copilot. * Fix HeadObject action name in docs for consistency Change 'HeadObject' to 's3:HeadObject' to match other action names. * Extract recheckPolicyWithObjectEntry helper to reduce duplication Move the repeated identity extraction and policy re-check logic from GetObjectHandler and HeadObjectHandler into a shared helper method. * Add validation for empty tag key in s3:ExistingObjectTag condition Prevent potential issues with malformed policies containing s3:ExistingObjectTag/ (empty tag key after slash).	2 months ago
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. 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>	3 months ago
