Chris Lu	b565a0cc86	Adds volume.merge command with deduplication and disk-based backend (#8441 ) * Enhance volume.merge command with deduplication and disk-based backend * Fix copyVolume function call with correct argument order and missing bool parameter * Revert "Fix copyVolume function call with correct argument order and missing bool parameter" This reverts commit `7b4a190643`. * Fix critical issues: per-replica writable tracking, tail goroutine cancellation via done channel, and debug logging for allocation failures * Optimize memory usage with watermark approach for duplicate detection * Fix critical issues: swap copyVolume arguments, increase idle timeout, remove file double-close, use glog for logging * Replace temporary file with in-memory buffer for needle blob serialization * test(volume.merge): Add comprehensive unit and integration tests Add 7 unit tests covering: - Ordering by timestamp - Cross-stream duplicate deduplication - Empty stream handling - Complex multi-stream deduplication - Single stream passthrough - Large needle ID support - LastModified fallback when timestamp unavailable Add 2 integration validation tests: - TestMergeWorkflowValidation: Documents 9-stage merge workflow - TestMergeEdgeCaseHandling: Validates 10 edge case handling All tests passing (9/9) * fix(volume.merge): Use time window for deduplication to handle clock skew The same needle ID can have different timestamps on different servers due to clock skew and replication lag. Needles with the same ID within a 5-second time window are now treated as duplicates (same write with timestamp variance). Key changes: - Add mergeDeduplicationWindowNs constant (5 seconds) - Replace exact timestamp matching with time window comparison - Use windowInitialized flag to properly detect window transitions - Add TestMergeNeedleStreamsTimeWindowDeduplication test This ensures that replicated writes with slight timestamp differences are properly deduplicated during merge, while separate updates to the same file ID (outside the window) are preserved. All tests passing (10/10) * test: Add volume.merge integration tests with 5 comprehensive test cases * test: integration tests for volume.merge command * Fix integration tests: use TripleVolumeCluster for volume.merge testing - Created new TripleVolumeCluster framework (cluster_triple.go) with 3 volume servers - Rebuilt weed binary with volume.merge command compiled in - Updated all 5 integration tests to use TripleVolumeCluster instead of DualVolumeCluster - Tests now properly allocate volumes on 2 servers and let merge allocate on 3rd - All 5 integration tests now pass: - TestVolumeMergeBasic - TestVolumeMergeReadonly - TestVolumeMergeRestore - TestVolumeMergeTailNeedles - TestVolumeMergeDivergentReplicas * Refactor test framework: use parameterized server count instead of hardcoded - Renamed TripleVolumeCluster to MultiVolumeCluster with serverCount parameter - Replaced hardcoded volumePort0/1/2 with slices for flexible server count - Updated StartTripleVolumeCluster as backward-compatible wrapper calling StartMultiVolumeCluster(t, profile, 3) - Made directory creation, port allocation, and server startup loop-based - Updated accessor methods (VolumeAdminAddress, VolumeGRPCAddress, etc.) to support any server count - All 5 integration tests continue to pass with new parameterized cluster framework - Enables future testing with 2, 4, 5+ volume servers by calling StartMultiVolumeCluster directly * Consolidate cluster frameworks: StartDualVolumeCluster now uses MultiVolumeCluster - Made DualVolumeCluster a type alias for MultiVolumeCluster - Updated StartDualVolumeCluster to call StartMultiVolumeCluster(t, profile, 2) - Removed duplicate code from cluster_dual.go (now just 17 lines) - All existing tests using StartDualVolumeCluster continue to work without changes - Backward compatible: existing code continues to use the old function signatures - Added wrapper functions in cluster_multi.go for StartTripleVolumeCluster - Enables unified cluster management across all test suites * Address PR review comments: improve error handling and clean up code - Replace parse error swallow with proper error return - Log cleanup and restoration errors instead of silently discarding them - Remove unused offset field from memoryBackendFile struct - Fix WriteAt buffer truncation bug to preserve trailing bytes - All unit tests passing (10/10) - Code compiles successfully * Fix PR review findings: test improvements and code quality - Add timeout to runWeedShell to prevent hanging - Add server 1 readonly status verification in tests - Assert merge fails when replicas writable (not just log output) - Replace sleep with polling for writable restoration check - Fix WriteAt stale data snapshot bug in memoryBackendFile - Fix startVolume error logging to show current server log - Fix volumePubPorts double assignment in port allocation - Rename test to reflect behavior: DoesNotDeduplicateAcrossWindows - Fix misleading dedup window comment Unit tests: 10/10 passing Binary: Compiles successfully * Fix test assumption: merge command marks volumes readonly automatically TestVolumeMergeReadonly was expecting merge to fail on writable volumes, but the merge command is designed to mark volumes readonly as part of its operation. Fixed test to verify merge succeeds on writable volumes and properly restores writable state afterward. Removed redundant Test 2 code that duplicated the new behavior. * fmt * Fix deduplication logic to correctly handle same-stream vs cross-stream duplicates The dedup map previously used only NeedleId as key, causing same-stream overwrites to be incorrectly skipped as duplicates. Changed to track which stream first processed each needle ID in the current window: - Cross-stream duplicates (same ID from different streams, within window) are skipped - Same-stream duplicates (overwrites from same stream) are kept - Map now stores: needleId -> streamIndex of first occurrence in window Added TestMergeNeedleStreamsSameStreamDuplicates to verify same-stream overwrites are preserved while cross-stream duplicates are skipped. All unit tests passing (11/11) Binary compiles successfully	2 weeks ago
