+1,51 @@ +[Chucky](https://github.com/acquire-project/chucky) is a replacement for the +acquire-zarr backend. It's fairly feature complete, but constitutes a pretty +big change. It is more performant, adds gpu acceleration, and adds some +flexibility around how levels-of-detail are computed. + +Integrating with acquire-zarr will be done in a few steps. First, we'll build +a library that implements acquire-zarr's public c api, and get that running. + +That's what this `shim` folder is all about. We'll build that out here, and +depending on how that goes, we may migrate over to the new backend more +permanently. + +## Building and testing + +The shim builds inside a Docker container (CUDA toolkit required even for the +CPU-only backend because chucky's CMake enables the CUDA language). + +Build and run all tests (filesystem + S3 via MinIO): + +``` +docker compose -f shim/docker-compose.yml up --build +``` + +Run a single test: + +``` +docker compose -f shim/docker-compose.yml run test \ + ctest --test-dir shim/build -R stream-raw-to-filesystem --output-on-failure +``` + +Tear down: + +``` +docker compose -f shim/docker-compose.yml down +``` + +## Library + +The shim produces a static library called `acquire-zarr-chucky-cpu`. It +implements all 28 functions from `include/acquire.zarr.h` by translating +acquire-zarr types into chucky's C API and forwarding calls. + +This is the CPU-only variant. A GPU variant will follow separately. + +## Known differences from the original acquire-zarr + +- **Compression codecs**: acquire-zarr wraps lz4/zstd inside Blosc1. Chucky + uses raw lz4/zstd. The `level` and `shuffle` compression parameters are + accepted but ignored. The zarr.json codec metadata will differ. +- **Thread count**: `max_threads` is accepted but ignored.

But append() sleeps on frame_queue_not_full_cv_ once the queue fills up, so once the worker returned the producer could deadlock forever. The destructor then hung in finalize_frame_queue_() because the wait predicate (!frame_queue_->empty() && !frame_queue_processing_done_) never became true either. On each early-exit path, now clear the queue and notify all three relevant CVs (not_full, empty, finished) under the mutex, and set process_frames_=false so any producer that retries exits immediately. Belt-and-suspenders: finalize_frame_queue_() now waits with a 30s timeout and logs an error if it expires, so a future regression in the worker cannot hang shutdown indefinitely. Also wrap write_frame() in a try/catch so that a CHECK() throw from a failing compress_and_flush_data_ (issue #220) is caught and surfaced via set_error_(), instead of propagating out of the worker thread and calling std::terminate. The error then becomes visible to the next append() via the existing error_ check.
