It keeps FullKV store data in a memory-mapped file so cold pages are reclaimable by the kernel under memory pressure, instead of pinning everything on the non-reclaimable Go heap — this addresses production OOMs with large or highly concurrent stores. The in-memory backend remains the default and is byte-for-byte unchanged; mmap is validated to produce identical output. **The scratch-space directory holding the bbolt files (`StoresScratchSpace`, OS temp dir if unset) must live on a local NVMe SSD**: the store is continuously read from and written to through the mmap, and the kernel pages it straight to that file, so a slow or network-backed disk turns store operations into an I/O bottleneck and negates the benefit. Do not point it at network/EBS-class storage. + - Server: cached deterministic errors now expire. Each error file carries a write timestamp in its name (`errors...`), and on read tier1 discards any error older than `SUBSTREAMS_DETERMINISTIC_ERROR_MAX_AGE` (Go duration, default `1h`), retrying execution. Legacy error files without a timestamp are deleted on read. - Server: new `ProcessRangeRequest.merged_blocks_bundle_size` field (internal tier1→tier2 protocol) carrying the number of blocks per merged-blocks file. `0` (older tier1s) means the historical default of `100`. Tier2 applies the value per-request, so a single tier2 can serve chains with different merged-blocks sizes. **Upgrade all tier2s before setting a non-100 value on any tier1**: older tier2s ignore the field and would read the store with a bundle size of 100 (jobs stall on missing file names). @@ -32,12 +34,10 @@ The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/), ### Fixed +- Server: canceled store loads now abort promptly instead of reading the entire (multi-GB) store file into the heap before returning. A tier2 store `Load` now checks the request context while streaming entries, so a canceled/disconnected request stops hydrating immediately. Also `memoryKVImpl.Close()` now drops its backing map (was a no-op), and the post-load `SetMetadata` goroutine no longer captures the whole loaded store (only the object store, filename and metadata) and runs under a bounded 30s timeout — together these stop a finished/canceled request from transiently pinning gigabytes of store data. - Server: a Blocks request whose start block resolves (from a cursor) to exactly the exclusive stop block now completes cleanly instead of returning `InvalidArgument: start block and stop block are the same`. The range is empty (stop is exclusive), so the stream is already done; this previously surfaced as a fatal, non-retryable error to clients that reconnected with a cursor sitting on the last block of the range after a transient disconnect. Raw (cursor-less) requests with `start == stop` still return the InvalidArgument as before. - - Sink: when resuming from a cursor already at or past the stop block, the sinker now shuts down immediately instead of opening a stream to the server. The pre-flight check previously compared the cursor against `adjustedEndBlock()` (stop block inflated by the partial-blocks buffer capacity), so a cursor sitting in the `[stopBlock-1, stopBlock+bufferCap-1)` window was let through and issued a useless request; it now compares against the raw exclusive `StopBlock`. - - Server: client disconnects (`context canceled`) on a tier1 Blocks stream are no longer logged as `WARNING`/`ERROR`. `toGrpcTier1Error` returned a `connect` error for the canceled case (unlike every other branch, which returns a gRPC `status` error), so the caller's `status.Code()` resolved to `Unknown` — logging the request completion as a WARN and the gRPC middleware call as an ERROR with `code Unknown`. It now returns `codes.Canceled`, so the disconnect is logged at Debug/Info as intended. - - Server: bumped `dstore`, which now sends S3 request checksums only when the target requires them, fixing uploads/downloads against S3-compatible stores that reject the newer default checksum headers. - Server: the quicksave block count now counts settled blocks (normal or last-partial) instead of skipping partials entirely, so quicksave arms correctly on flash-block chains. The minimum sent-block threshold before a quicksave triggers was raised from 25 to 50. - Server: `tier1` calls to hosted foundational stores now forward the `x-organization-id` identity header (alongside the existing trusted headers), so a store's internal trust-based listener can authorize the request without an end-user JWT. This fixes `Unauthenticated: required authorization token not found` errors when reading from hosted foundational stores resolved via the control-plane registry. diff --git a/go.mod b/go.mod index
