RocheDB v0.7.0

RocheDB v0.7.0 is a technical-preview release focused on hardening the storage,
wire, C ABI, TLS, and universe-sync paths while keeping RocheDB's scope honest:
it is still not presented as a production replacement for Redis, PostgreSQL,
MongoDB, Apache Arrow, or dedicated vector databases.

Release:

https://github.com/puffball1567/rochedb/releases/tag/v0.7.0

The main goal of this release is to reduce the number of silent-failure paths
around persistence, driver-facing builds, sync acknowledgements, and operational
misconfiguration. It also expands the runnable demo and smoke matrix so
RocheDB's locality model can be checked with more than happy-path examples.

Main Changes

  • Added scripts/build_capi.sh as the canonical C ABI shared-library build
    path. It builds with --app:lib -d:ssl -d:release.
  • Updated driver installation docs and compatibility scripts to use the
    canonical C ABI build path.
  • Added C ABI TLS smoke coverage.
  • Added Linux and macOS CI coverage for the C ABI build path.
  • Enabled --panics:on so internal Defects do not become false success values
    through C ABI calls.
  • Added persistent data-directory locking to prevent two processes from
    opening the same store and corrupting transaction identity.
  • Hardened universe sync acknowledgement handling, retry accounting,
    dead-letter handling, remote sync recovery, and idempotent replay.
  • Added bounded applied-event dedup persistence for universe sync.
  • Added server-side retrieve budget and scan guards for safer broad queries.
  • Added lock fencing-token persistence for ring and stellar locks.
  • Added docs/data-migration.md for JSONL dump/import as the main pre-v1
    compatibility boundary.
  • Added docs/time-orbit.md for calculated time-bucket placement.
  • Added scripts/demo_smoke.sh to exercise stellar, codec, and locality demos.
  • Added cluster wire driver smoke coverage to the full smoke suite.

Why This Release Matters

RocheDB's main bet is that meaningful placement can reduce unnecessary reads,
transfers, memory pressure, and downstream AI/RAG work. v0.7.0 does not change
that thesis; it makes the implementation more trustworthy around the boring
parts that matter for databases:

  • storage must fail closed when a directory is already open elsewhere
  • C ABI callers must not see false success after internal Defects
  • TLS-capable driver builds need one canonical command
  • universe sync must not prune events unless the target actually accepted them
  • broad reads need explicit limits and diagnostics
  • demo and smoke scripts must keep proving that core workflows still run

Example: C ABI Build

scripts/build_capi.sh

The script writes the shared library to build/capi/ and is the recommended
path for Rust, JavaScript / TypeScript, PHP, C++, Swift, Kotlin, Go, and C#
driver work.

Example: Full Smoke

scripts/test_all_smoke.sh

The all-smoke suite now includes:

  • core tests
  • CLI CRUD smoke
  • cluster transaction and failure recovery smoke
  • authz / RBAC smoke
  • driver wire-protocol smoke
  • wire fuzz smoke
  • TLS smoke
  • recovery smoke
  • universe sync failure and remote sync smoke
  • demo smoke

Documentation

New and updated documents include:

  • docs/audit-remediation.md
  • docs/data-migration.md
  • docs/time-orbit.md
  • docs/driver-installation.md
  • docs/protocol-compatibility.md
  • docs/tls-transport.md
  • docs/threat-model.md
  • docs/query-safety.md
  • docs/public-api.md
  • docs/test-coverage.md
  • docs/release-checklist.md
  • docs/rochedb-status.md

Verification

The local release verification pass included:

  • scripts/test_all_smoke.sh
  • nimble check

scripts/test_all_smoke.sh includes the expanded cluster, TLS, recovery,
universe-sync, codec, stellar, and locality demo checks listed above.

Known Boundaries

  • RocheDB remains a technical preview / research OSS.
  • Online dynamic membership and live rebalance are still planned, not complete.
  • Cluster transaction coordinator redundancy is still planned.
  • Universe sync remains a durable eventual-convergence primitive, not a
    consensus or quorum system.
  • JSONL dump/import is the recommended compatibility boundary before v1.0.
  • External driver packages may lag the core C ABI surface and should be checked
    against their own package release notes.
