The API's lifespan unconditionally spawned a MACVLAN sniffer task, which
duplicated the standalone 'decnet sniffer --daemon' process that
'decnet deploy' always starts — causing two workers to sniff the same
interface, double events, and wasted CPU.
Mirror the existing DECNET_EMBED_PROFILER pattern: sniffer is OFF by
default, opt in explicitly. Static regression tests guard against
accidental removal of the gate.
New `profile` optional-deps group, opt-in Pyinstrument ASGI middleware
gated by DECNET_PROFILE_REQUESTS, bench marker + tests/perf/ micro-benchmarks
for repository hot paths, and scripts/profile/ helpers for py-spy/cProfile/memray.
Gated by DECNET_DEVELOPER_TRACING env var (default off, zero overhead).
When enabled, traces flow through FastAPI routes, background workers
(collector, ingester, profiler, sniffer, prober), engine/mutator
operations, and all DB calls via TracedRepository proxy.
Includes Jaeger docker-compose for local dev and 18 unit tests.
decnet deploy spawns a standalone profiler daemon AND api.py was also starting
attacker_profile_worker as an asyncio task inside the web server. Both instances
shared the same attacker_worker_cursor key in the state table, causing a race
where one instance could skip events already claimed by the other or overwrite
the cursor mid-batch.
Default is now OFF (embedded profiler disabled). The standalone daemon started
by decnet deploy is the single authoritative instance. Set DECNET_EMBED_PROFILER=true
only when running decnet api in isolation without a full deploy.
- Add `get_repository()` factory function to select DB implementation at runtime via DECNET_DB_TYPE env var
- Extract BaseRepository abstract interface from SQLiteRepository
- Update dependencies to use factory-based repository injection
- Add DECNET_DB_TYPE env var support (defaults to sqlite)
- Refactor models and repository base class for cross-dialect compatibility
- decnet/env.py: DECNET_JWT_SECRET and DECNET_ADMIN_PASSWORD are now
required env vars; startup raises ValueError if unset or set to a
known-bad default ("admin", "password", etc.)
- decnet/env.py: add DECNET_CORS_ORIGINS (comma-separated, defaults to
http://localhost:8080) replacing the previous allow_origins=["*"]
- decnet/web/api.py: use DECNET_CORS_ORIGINS and tighten allow_methods
and allow_headers to explicit lists
- tests/conftest.py: set required env vars at module level so test
collection works without real credentials
- tests/test_web_api.py, test_web_api_fuzz.py: use DECNET_ADMIN_PASSWORD
from env instead of hardcoded "admin"
