* fix unit tests, bump actions-timeline CI is failing to startup to run unit tests, complaining about actions-timeline version not being allowed, switched to latest per https://github.com/apache/infrastructure-actions/blob/main/actions.yml * fix S3InputSourceTest
changes: * add `PartialSegmentMetadataCacheEntry` a `CacheEntry` that range-reads the V10 header on mount, constructs `PartialSegmentFileMapperV10`, and shrinks its reservation to actual on-disk size * add `PartialSegmentBundleCacheEntry` and `PartialSegmentBundleCacheEntryIdentifier` are `CacheEntry` associated with each file bundle of a v10 segment that sparse-allocates and evicts its containers as a unit; places holds metadata and transitive parent bundle entries holds via the `StorageLocation` methods (weak reference holds on the parent cache entries) and reference-counted usage references * add `PartialSegmentCacheBootstrap` a helper that restores partial-format entries from on-disk layout on historical startup (not wired up yet); cleans orphaned bundles * add `ResizableCacheEntry` interface and `StorageLocation.adjustReservation` (shrink-only) so the metadata entry can tighten its reservation post-mount * rename `SegmentFileBuilder.startFileGroup` → `startFileBundle`; introduce `ROOT_BUNDLE_NAME` as the default bundle for containers written without an explicit declaration * rename json field `SegmentFileContainerMetadata.fileGroup` → `bundle`; now non-null via getter, normalizes to `ROOT_BUNDLE_NAME` in the constructor, default value omitted from JSON using a custom `JsonInclude` filter * Extract shared `DirectoryBackedRangeReader` and `CountingRangeReader` test helpers; consolidate duplicates across processing + server tests
…#19491) (apache#19497) OrcInputFormat.initialize() — which swaps Thread.currentThread().setContextClassLoader() and calls FileSystem.get(conf) — was invoked on every createReader() call. When a ParallelIndexTask runs multiple ORC subtasks concurrently in the same JVM (as in embedded tests)
