* Table Commit Operations (handleUpdateTable)
* s3tables: fix Iceberg v2 compliance and namespace properties
This commit ensures SeaweedFS Iceberg REST Catalog is compliant with
Iceberg Format Version 2 by:
- Using iceberg-go's table.NewMetadataWithUUID for strict v2 compliance.
- Explicitly initializing namespace properties to empty maps.
- Removing omitempty from required Iceberg response fields.
- Fixing CommitTableRequest unmarshaling using table.Requirements and table.Updates.
* s3tables: automate Iceberg integration tests
- Added Makefile for local test execution and cluster management.
- Added docker-compose for PyIceberg compatibility kit.
- Added Go integration test harness for PyIceberg.
- Updated GitHub CI to run Iceberg catalog tests automatically.
* s3tables: update PyIceberg test suite for compatibility
- Updated test_rest_catalog.py to use latest PyIceberg transaction APIs.
- Updated Dockerfile to include pyarrow and pandas dependencies.
- Improved namespace and table handling in integration tests.
* s3tables: address review feedback on Iceberg Catalog
- Implemented robust metadata version parsing and incrementing.
- Ensured table metadata changes are persisted during commit (handleUpdateTable).
- Standardized namespace property initialization for consistency.
- Fixed unused variable and incorrect struct field build errors.
* s3tables: finalize Iceberg REST Catalog and optimize tests
- Implemented robust metadata versioning and persistence.
- Standardized namespace property initialization.
- Optimized integration tests using pre-built Docker image.
- Added strict property persistence validation to test suite.
- Fixed build errors from previous partial updates.
* Address PR review: fix Table UUID stability, implement S3Tables UpdateTable, and support full metadata persistence individually
* fix: Iceberg catalog stable UUIDs, metadata persistence, and file writing
- Ensure table UUIDs are stable (do not regenerate on load).
- Persist full table metadata (Iceberg JSON) in s3tables extended attributes.
- Add `MetadataVersion` to explicitly track version numbers, replacing regex parsing.
- Implement `saveMetadataFile` to persist metadata JSON files to the Filer on commit.
- Update `CreateTable` and `UpdateTable` handlers to use the new logic.
* test: bind weed mini to 0.0.0.0 in integration tests to fix Docker connectivity
* Iceberg: fix metadata handling in REST catalog
- Add nil guard in createTable
- Fix updateTable to correctly load existing metadata from storage
- Ensure full metadata persistence on updates
- Populate loadTable result with parsed metadata
* S3Tables: add auth checks and fix response fields in UpdateTable
- Add CheckPermissionWithContext to UpdateTable handler
- Include TableARN and MetadataLocation in UpdateTable response
- Use ErrCodeConflict (409) for version token mismatches
* Tests: improve Iceberg catalog test infrastructure and cleanup
- Makefile: use PID file for precise process killing
- test_rest_catalog.py: remove unused variables and fix f-strings
* Iceberg: fix variable shadowing in UpdateTable
- Rename inner loop variable `req` to `requirement` to avoid shadowing outer request variable
* S3Tables: simplify MetadataVersion initialization
- Use `max(req.MetadataVersion, 1)` instead of anonymous function
* Tests: remove unicode characters from S3 tables integration test logs
- Remove unicode checkmarks from test output for cleaner logs
* Iceberg: improve metadata persistence robustness
- Fix MetadataLocation in LoadTableResult to fallback to generated location
- Improve saveMetadataFile to ensure directory hierarchy existence and robust error handling
