dynos_sync 0.1.8

🛡️ Production-hardened, high-performance sync engine for Dart & Flutter. Built for 50k+ writes/sec, delta-pulls, and zero-jank offline-first reliability.

CHANGELOG

0.1.8 - 2026-08-28

• Fix (data corruption): SyncEngine.write() and SyncEngine.push() no longer apply SyncConfig.sensitiveFields masking to the payload that is persisted locally and queued for remote push. Any field listed in sensitiveFields was silently replaced with the literal string '[REDACTED]' in the local store (write() path) and in every pushed payload — permanently destroying the real values on the remote, or failing the push outright on non-text columns (e.g. numeric/double precision reject the string, leaving the queue stuck retrying). Masking now applies only where it was documented to: error contexts passed to onError and emitted sync events. Callers who need a field kept off the server entirely should omit it from the payload.
• Updated the three tests that asserted masked payloads were stored/pushed; added regression tests pinning real-value passthrough for both write() and push().

0.1.7 - 2026-08-27

• Fix (data integrity): SyncEngine._pullTable now derives each table's delta watermark from the newest server updated_at in the pulled rows, instead of the device wall clock (DateTime.now()). A device whose clock ran ahead of the server would persist a future watermark, after which pullSince's updated_at > since filter silently skipped every row the server committed in the gap — unbounded, permanent data loss. If no pulled row carries a parseable updated_at, the watermark is left unchanged (safe re-pull) rather than guessing now().
• Added test/watermark_clock_skew_test.dart regression suite.

0.1.6 - 2026-03-28

• Real background isolate: IsolateSyncEngine now uses Isolate.run() with an engineFactory constructor for true off-main-thread sync. Previous implementation was a non-functional stub.
• Dead code removal: Removed unused _getRetryDelay helper from SyncEngine.
• Test audit: Updated test suite header to correctly reflect 140 tests across 13 categories.

0.1.5 - 2026-03-22

• Patch operation: Added SyncOperation.patch for partial updates. Sends UPDATE instead of upsert, avoiding NOT NULL constraint failures when only a few fields change.
• Updated SupabaseRemoteStore to handle patch in both push() and pushBatch().

0.1.4 - 2026-03-22

• 100% dartdoc coverage: Added documentation comments to all 225 public API elements.

0.1.3 - 2026-03-22

• Runtime table management: addTable() and removeTable() allow registering/unregistering sync tables after engine creation.
• 130-test security audit: Comprehensive audit across 12 categories (HIPAA, GDPR, OWASP Mobile Top 10, injection, flood testing, chaos engineering, conflict resolution, race conditions, denial of service).
• Updated documentation: README rewritten with complete API reference. Architecture and security docs rewritten for developers.

0.1.2 - 2026-03-21 - Global Open Source Milestone

• License Shift: Transitioned from BSL-1.1 to MIT License for unrestricted public use.
• Score Optimization: Now achieving 100/100 Points on pub.dev.

0.1.1 - 2026-03-21

• Corrected Metadata: Finalized hyphenated repository URL for pub.dev analysis.
• Performance Stability: Verified 50k+ writes/sec ingestion.

0.1.0 - 2026-03-21

Initial Public Release.

• Production-Hardened Engine: Subjected to a 42-point security audit.
• High-Scale Ingestion: High-performance local writes (50k+ writes/sec).
• Advanced Privacy: Built-in PII redaction and secure session purging.
• Background Efficiency: Full support for dedicated Background Isolates.
