What's in v0.2.3

Bug-fix release. All fixes ship in the WASM playground bundle and the published Python/npm packages.

Fixes

  • GZIP-compressed Parquet now decodes in the engine (codec=2). miniz-based deflate path with a manual RFC 1952 header peel. (#7)
  • ZSTD-compressed Parquet now decodes (codec=6). Vendored libzstd 1.5.6 decompression-only subset, BSD-3, ~50 KB compiled. (#7)
  • read_parquet glob expansion works in the WASM playground. SELECT * FROM '/data/shard_*.parquet' now correctly fans out across all matching files instead of failing with Cannot open Parquet. (#6)
  • Single-threaded WASM no longer crashes on GROUP BY. std::thread spawns are now gated through a HWThreads() helper that returns 1 on __EMSCRIPTEN__ && !__EMSCRIPTEN_PTHREADS__ and runs the worker inline.
  • Playground cache-buster bumped to 20260428-1 so any open browser tab refetches the new WASM/JS on next load.

Verification

  • 22/22 format smoke tests green.
  • 100k-row Parquet on SNAPPY / GZIP / ZSTD return identical aggregates, native and WASM.
  • 39 MB real-world TPC-H orders Parquet (30 row groups, mixed encodings) reads in ~40 ms via WASM in Node.

Upgrade

  • Python: pip install --upgrade slothdb (already published as 0.2.3 sdist; binary wheels follow CI).
  • WASM: npm install @slothdb/wasm@0.2.3.
  • Playground: just refresh the page; new cache-buster forces a clean fetch.

If you hit a stale cached version, hard-refresh once (Ctrl+Shift+R / Cmd+Shift+R).
