- Modify Rfc5424Formatter to read decnet_component from LogRecord
and use it as RFC 5424 APP-NAME field (falls back to 'decnet')
- Add get_logger(component) factory in decnet/logging/__init__.py
with _ComponentFilter that injects decnet_component on each record
- Wire all five layers to their component tag:
cli -> 'cli', engine -> 'engine', api -> 'api' (api.py, ingester,
routers), mutator -> 'mutator', collector -> 'collector'
- Add structured INFO/DEBUG/WARNING/ERROR log calls throughout each
layer per the defined vocabulary; DEBUG calls are suppressed unless
DECNET_DEVELOPER=true
- Add tests/test_logging.py covering factory, filter, formatter
component-awareness, fallback behaviour, and level gating
- Fixed CLI tests by patching local imports at source (psutil, os, Path).
- Fixed Collector tests by globalizing docker.from_env mock.
- Stabilized SSE stream tests via AsyncMock and immediate generator termination to prevent hangs.
- Achieved >80% coverage on CLI (84%), Collector (97%), and DB Repository (100%).
- Implemented SMTP Relay service tests (100%).
- Add merge-to-testing job: after all CI checks pass on dev, auto-merge
into testing with --no-ff for clear merge history
- Move open-pr job to trigger on testing branch instead of dev
- PR now opens testing → main instead of dev → main
- Add bandit and pip-audit jobs to pr.yml PR gate for full suite coverage
- PR gate test job now installs dev dependencies consistently
Spins up each service's server.py in a real subprocess via a free ephemeral
port (PORT env var), connects with real protocol clients, and asserts both
correct protocol behavior and RFC 5424 log output.
- 44 live tests across 10 services: http, ftp, smtp, redis, mqtt,
mysql, postgres, mongodb, pop3, imap
- Shared conftest.py: _ServiceProcess (bg reader thread + queue),
free_port, live_service fixture, assert_rfc5424 helper
- PORT env var added to all 10 targeted server.py templates
- New pytest marker `live`; excluded from default addopts run
- requirements-live-tests.txt: flask, twisted + protocol clients
MongoDB had the same infinite-loop bug as MSSQL (msg_len=0 → buffer never
shrinks in while loop). Postgres, MySQL, and MQTT had related length-field
issues (stuck state, resource exhaustion, overlong remaining-length).
Also fixes an existing MongoDB _op_reply struct.pack format bug (extra 'q'
specifier caused struct.error on any OP_QUERY response).
Adds 53 regression + protocol boundary tests across MSSQL, MongoDB,
Postgres, MySQL, and MQTT, including a _run_with_timeout threading harness
to catch infinite loops and @pytest.mark.fuzz hypothesis tests for each.
Cowrie was exposing an SSH daemon on port 22 alongside the telnet service
even when COWRIE_SSH_ENABLED=false, contaminating deployments that did not
request an SSH service.
New implementation mirrors the SSH service pattern:
- busybox telnetd in foreground mode on port 23
- /bin/login for real PAM authentication (brute-force attempts logged)
- rsyslog RFC 5424 bridge piped to stdout for Docker log capture
- Configurable root password and hostname via env vars
- No Cowrie dependency
real_ssh was a separate service name pointing to the same template and
behaviour as ssh. Merged them: ssh is now the single real-OpenSSH service.
- Rename templates/real_ssh/ → templates/ssh/
- Remove decnet/services/real_ssh.py
- Deaddeck archetype updated: services=["ssh"]
- Merge test_real_ssh.py into test_ssh.py (includes deaddeck + logging tests)
- Drop decnet.services.real_ssh from test_build module list
The collector subprocess was spawned via 'python3 -m decnet.cli collect'
but cli.py had no 'if __name__ == __main__: app()' guard. Python executed
the module, defined all functions, then exited cleanly with code 0 without
ever calling the collect command. No output, no log file, exit 0 — silent
non-start every time.
Also route collector stderr to <log_file>.collector.log so future crashes
are visible instead of disappearing into DEVNULL.
Collector and mutator watcher subprocesses were spawned without
start_new_session=True, leaving them in the parent's process group.
SIGHUP (sent when the controlling terminal closes) killed both
processes silently — stdout/stderr were DEVNULL so the crash was
invisible.
Also update test_services and test_composer to reflect the ssh plugin
no longer using Cowrie env vars (replaced with SSH_ROOT_PASSWORD /
SSH_HOSTNAME matching the real_ssh plugin).
Scraps the Cowrie emulation layer. The real_ssh template now runs a
genuine sshd backed by a three-layer logging stack forwarded to stdout
as RFC 5424 for the DECNET collector:
auth,authpriv.* → rsyslogd → named pipe → stdout (logins/failures)
user.* → rsyslogd → named pipe → stdout (PROMPT_COMMAND cmds)
sudo syslog=auth → rsyslogd → named pipe → stdout (privilege escalation)
sudo logfile → /var/log/sudo.log (local backup with I/O)
The ssh.py service plugin now points to templates/real_ssh and drops all
COWRIE_* / NODE_NAME env vars, sharing the same compose fragment shape as
real_ssh.py.
_load_service_container_names() reads decnet-state.json and builds the
exact set of expected container names ({decky}-{service}). is_service_container()
and is_service_event() do a direct set lookup — no regex, no label
inspection, no heuristics.
