Filer-level tests (filechunk_manifest_test.go):
- TestManifestRoundTripPreservesChunks: create -> serialize -> deserialize
preserves fileId, offset, size, and timestamp for all sub-chunks
- TestCompactResolvedOverlappingManifests: two manifests covering the same
range, older sub-chunks correctly identified as garbage after compaction
- TestDoMinusChunksWithResolvedManifests: old manifest sub-chunks detected
as garbage when compared against new clean chunks (mirrors filer cleanup)
- TestManifestizeSmallBatchWithRemainder: batch=3 with 7 chunks produces
2 manifests + 1 remainder, all data recoverable after resolve
- TestCompactMultipleOverlappingManifestGenerations: 5 generations of
full-file manifests, compaction keeps only the newest generation
- TestManifestBloatDetection: with N overlapping manifests, merge triggers
at N >= 2 (stored > 2x file size)
Mount-level test (weedfs_file_sync_test.go):
- TestFlushCycleManifestAccumulation: simulates the flushMetadataToFiler
pipeline over multiple cycles with a small manifest batch (5 chunks).
Verifies merge triggers at cycle 2 when accumulated manifests exceed
the 2x threshold. Uses SeparateManifestChunks + CompactFileChunks +
shouldMergeChunks to mirror the real code path.
