Expand both topology diagrams to show the retry queue and healing pass in
the flow. Add per-topology failure-behaviour tables covering transient backend
failure, prolonged outage, container-down-during-push, and cross-node drift.
Rewrite the comparison table to call out the key architectural difference:
Topology A has no auto-recovery from prolonged BIND failure (needs next DA push);
Topology B's reconciler healing pass re-syncs missing backends from stored
zone_data without any DA involvement.
- worker.py: third persistent retry queue with exponential backoff (30s→30m,
max 5 attempts); failed backends tracked per-item so retries target only the
failing nodes; zone_data stored in DB after every successful write
- Domain model: zone_data TEXT + zone_updated_at DATETIME columns; additive
migration applied on startup so existing deployments upgrade in place
- ReconciliationWorker: Option C healing pass — checks every configured backend
for zone presence after each reconciliation cycle and re-queues any zone
missing from a backend using stored zone_data, enabling automatic recovery
from prolonged backend outages without waiting for DirectAdmin to re-push
- 82 tests, all passing
- entrypoint: only start named when a bind backend is configured and
enabled in app.yml; CoreDNS-only deployments skip named entirely
- config: user-supplied paths (/etc/directdnsonly, ./config) now
searched before the bundled app.yml so mounted configs take effect
- docs: deployment topology reference — Topology A (dual BIND HA) and
Topology B (single instance, multi-DC CoreDNS MySQL)
- chore: bump version to 2.1.0
- justfile: add build-docker recipe
- Migrated from setuptools to Poetry; added pyproject.toml, poetry.lock,
poetry.toml and .python-version (Python 3.11.12)
- Built out full directdnsonly Python package with BIND and CoreDNS MySQL
backends, CherryPy REST API, persist-queue worker, and vyper-based config
- Auth credentials now read from config/env (app.auth_username/password)
rather than hardcoded; override via DADNS_APP_AUTH_PASSWORD env var
- Added Dockerfile.deepseek: Python 3.11 slim + BIND9 + Poetry install
- Rewrote docker-compose.yml for local dev stack (MySQL + dadns services)
- Added SQL schema, docker/ BIND configs, justfile, tests, and README
- Expanded .gitignore for Poetry/Python project artifacts
