A device with a real null tag (e.g. tags\n(null, b, c)) and a device whose tag value is the string \"null\"\n((\"null\", b, c)) therefore produce the identical name \"a.null.b.c\" and\ncollide in the cache: whichever device is queried first populates the\nentry, and every later query for the other device on the same reused\nreader gets the first device\u0027s cached MetaIndexNode and silently reads\nits chunks.\n\nThis surfaced through the Python dataset API, where one long-lived\nTsFileReader answers many per-device queries: the pytest\ntest_dataset_null_tag_positions_and_string_null_are_distinct read\n(null,b,c)\u0027s data for the (\"null\",b,c) device. The device metadata\nbinary search (DeviceIDComparable, segment-based) was always correct;\nonly the string cache key was lossy.\n\nKey the cache by a collision-free, length-prefixed encoding of the\nsegment vector that flags null segments explicitly, so a null tag can\nnever alias the string \"null\". Add a device_id unit test pinning the\ninvariant (names collide, segment equality distinguishes them).\n\nVerified: C++ suite 707/707 (Release+ASan+UBSan), Python suite 150/150.\n\n* build: don\u0027t use -march\u003dnative by default; gate it behind an option\n\nRelease builds unconditionally added -march\u003dnative on Linux/macOS. Two\nproblems for artifacts that leave the build host:\n\n1. Portability: a wheel/binary built on a newer CPU can fault with an\n illegal instruction on an older target machine.\n2. On virtualized macOS arm64 CI runners, -march\u003dnative mis-detects the\n feature set and drops +crc, while snappy\u0027s CRC32 feature probe (run\n without -march) still reports crc available and defines\n SNAPPY_HAVE_NEON_CRC32\u003d1. snappy.cc then calls the always_inline\n __crc32cw intrinsic in a TU compiled without crc support:\n error: always_inline function \u0027__crc32cw\u0027 requires target feature\n \u0027crc\u0027, but would be inlined into a function compiled without \u0027crc\u0027\n The default (portable) target for macOS arm64 keeps +crc, so snappy\u0027s\n fast path stays available while the binary stays portable.\n\nDefault Release flags are now -O3 -flto (LTO stays off on MinGW/Windows\nas before). -march\u003dnative is opt-in via -DTSFILE_ENABLE_NATIVE_ARCH\u003dON\nfor local-only builds that never ship. Applies uniformly to CI, wheels,\nand manual local builds.\n\nVerified: non-ASan Release (CI config) builds snappy cleanly and passes\n705/705; -DTSFILE_ENABLE_NATIVE_ARCH\u003dON restores -march\u003dnative.\n\n* fix comment.\n\n* fix simde.\n\n* fix memory leaks in TsFileSeriesScanIterator teardown\n\nThe SSI is placement-new\u0027d into mem_alloc\u0027d memory and torn down with\ndestroy() + mem_free() (TsFileIOReader::revert_ssi / alloc_ssi /\nalloc_multi_ssi), so ~TsFileSeriesScanIterator() never runs.

direct lookup for multi-tag-column devices\n\nThe TagEq direct B-tree lookup constructed a device ID with only\ncol_idx_+1 segments, but devices with multiple tag columns have more.\nThe segment count mismatch caused operator\u003d\u003d to always return false,\nso queries returned 0 rows. Guard the optimization to only activate\nwhen the filter fully specifies the device ID (single tag column).\n\n* add unit tests for timeseries metadata and direct B-tree lookup\n\n- GetTimeseriesMetadataTableModel: test get_timeseries_metadata()\n with table model, covering get_all_device_entries (LEAF_DEVICE\n path) and get_device_timeseries_meta_by_offset\n- GetTimeseriesMetadataMultiTable: test with two tables, covering\n the multi-table iteration in get_timeseries_metadata\n- DirectLookupSingleTagColumn: test the TagEq direct B-tree lookup\n optimization with a single-tag-column table, covering\n try_setup_direct_lookup and load_results_direct\n- DirectLookupNonExistDevice: test direct lookup returns 0 rows\n when the device does not exist\n\n* delete examples/bench_read.cpp\n\n* fix direct lookup guard for multi-tag-column tables\n\nThe previous guard (actual_segment_count !\u003d eq-\u003ecol_idx_ + 1) still\nallowed direct lookup when filtering on the last tag column in a\nmulti-tag table (e.g., 2 tags: segment_count\u003d3, col_idx\u003d2, 2+1\u003d3).\nThe constructed device ID had empty segments for unfiltered tags,\ncausing B-tree lookup to find nothing. Restrict direct lookup to\nsingle-tag tables only (segment_count \u003d\u003d 2).\n\n* style: clang-format\n\n---------\n\nCo-authored-by: Claude Opus 4.7 (1M context) \u003cnoreply@anthropic.com\u003e" }, { "commit": "86ec4b992b8b14e73daed915b90c8da8528a9213", "tree": "ef0e303812e94510fab886416095a3a82ca0c976", "parents": [ "e7b0d695738c6ec0446c1c004ff017dfe1295d4c" ], "author": { "name": "Zhenyu Luo", "email": "zhenyu@apache.org", "time": "Wed Jun 03 15:17:43 2026 +0800" }, "committer": { "name": "GitHub", "email": "noreply@github.com", "time": "Wed Jun 03 15:17:43 2026 +0800" }, "message": "Add Tablet.serializedSize() and comprehensive size validation tests.
