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.
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.
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.'
