[SECURITY] Production security logging with correlation IDs and audit trail - closes #55 by Ibrahim-3d · Pull Request #84 · sjackson0109/PowerTraderAI

Ibrahim-3d · 2026-05-17T20:49:36Z

Summary

Creates pt_security_logger.py as a standalone security event logging module (independent of pt_logging_system.py) providing security-specific event logging, correlation ID propagation, and a dedicated rotating audit log.

Changes

New: app/pt_security_logger.py
New: app/test_security_logger.py — 25 tests

Key features

Feature	Detail
Correlation IDs	CorrelationContext('cid') sets thread-local ID; CorrelationLogFilter injects into all records
Security events	AUTH_ATTEMPT/SUCCESS/FAILURE, CREDENTIAL_USE/ROTATION, SUSPICIOUS_ACTIVITY, PERMISSION_DENIED, TRADE_EXECUTED/REJECTED, SYSTEM_START/STOP
Audit log	Dedicated security_audit.jsonl, RotatingFileHandler (10MB/10 backups), owner-only permissions
Thread isolation	Each thread has its own correlation ID (threading.local)

Usage

\\python
from pt_security_logger import security_logger, CorrelationContext

Propagate correlation ID through a workflow

with CorrelationContext('order-workflow-abc') as cid:
security_logger.log_auth_attempt('robinhood', success=True)
security_logger.log_trade_event('BTC-USD', 'buy', 0.1, 45000.0)

Suspicious activity alert

security_logger.log_suspicious_activity(
'rate_limit_exceeded', source_ip='1.2.3.4',
details={'endpoint': '/orders', 'count': 150}
)
\\

Test plan

25 tests pass
Thread-local correlation ID isolation verified
Context manager restore/clear tested
All event types written and readable
Audit log rotation handler configured

Closes #55

…racking pt_security_logger.py: - SecurityLogger with RotatingFileHandler (10MB/10 backups), secure permissions, JSONL structured events - SecurityEventType enum: auth, credential, suspicious, trade, system events - correlation_context() thread-local context manager propagates request IDs - CorrelationLogFilter injects correlation_id into all LogRecords - Module-level security_logger singleton for application-wide use - 25 unit tests, all passing

pt_security_logger.py: - Module-level singleton is now lazy (get_security_logger()) — audit file not created at import time; default log_dir is ~/.powertraderai/logs, not the source tree; os.makedirs ensures dir exists before handler creation - Per-instance logging.Logger (not global registry) eliminates the shared-handler/_handler=None pitfall when two instances share a log_dir - _SecureRotatingFileHandler subclass overrides doRollover() to chmod active file and all backups after rotation - _chmod_secure() called once at handler creation, not on every _emit(); OSError logged as WARNING instead of silently swallowed - correlation_context renamed to CorrelationContext (PEP 8 CapWords); snake_case alias kept for backwards compatibility - CorrelationContext uses a _stack list so nested/reused instances are safe (no _previous corruption) - clear_correlation_id() uses del instead of setting to None - SecurityEvent.new_id() uses datetime.now(timezone.utc) for UTC IDs - get_recent_events() uses collections.deque(f, maxlen=limit) for O(limit) tail read instead of readlines() O(file size) - hashlib.md5 removed (per-instance logger needs no path hash) - Added log_rate_limit() and log_config_change() helpers for enum values that previously had no public method - Generator import removed (was unused) - Docstring updated: module does NOT extend pt_logging_system test_security_logger.py: - tearDown uses sec_logger.close() to release file handles - test_get_recent_events_empty_when_no_log: adds assertEqual([], ...) assertion - test_get_recent_events_limit: asserts returned events are the last N - Added test_new_id_uses_utc, test_context_manager_nested_safe, test_snake_case_alias_works, test_log_rate_limit, test_log_config_change

Manual Testing Guide — PR #84: Production Security Logging

Prerequisites

git fetch fork && git checkout feat/55-production-logging
cd app

1. Run unit tests

python -m pytest test_security_logger.py -v

Expected: All 25+ tests pass.

2. Smoke test — no file created at import time (key fix)

python -c "
import sys, os
# Record files in app/ before import
before = set(os.listdir('.'))
import pt_security_logger  # module import must NOT create security_audit.jsonl
after = set(os.listdir('.'))
new_files = after - before
print('new files on import:', new_files)
assert 'security_audit.jsonl' not in new_files, 'audit file created at import!'
print('PASS: no file created at import')
"

3. Smoke test — audit file goes to ~/.powertraderai/logs (key fix)

python -c "
import os, tempfile
from pt_security_logger import SecurityLogger

# Explicit log_dir
with tempfile.TemporaryDirectory() as d:
    sl = SecurityLogger(log_dir=d)
    sl.log_auth_attempt('binance', success=True)
    events = sl.get_recent_events()
    print('events logged:', len(events))
    assert len(events) == 1
    print('event_type:', events[0]['event_type'])
    sl.close()
print('PASS')
"

4. Verify correlation ID context nesting (key fix)

python -c "
from pt_security_logger import CorrelationContext, get_correlation_id, clear_correlation_id
import tempfile
clear_correlation_id()

ctx = CorrelationContext('outer')
with ctx:
    print('outer:', get_correlation_id())  # outer
    with ctx:
        print('nested:', get_correlation_id())  # outer (same instance reused safely)
    print('after inner exit:', get_correlation_id())  # outer
print('after outer exit:', get_correlation_id())  # None
print('PASS')
"

5. Verify rate_limit and config_change helpers exist (key fix)

python -c "
import tempfile
from pt_security_logger import SecurityLogger, SecurityEventType

with tempfile.TemporaryDirectory() as d:
    sl = SecurityLogger(log_dir=d)
    sl.log_rate_limit('robinhood', details={'endpoint': '/orders'})
    sl.log_config_change('risk_limits', details={'max_pos': 0.05})
    events = sl.get_recent_events()
    types = [e['event_type'] for e in events]
    print('event types:', types)
    assert SecurityEventType.RATE_LIMIT.value in types
    assert SecurityEventType.CONFIG_CHANGE.value in types
    sl.close()
print('PASS')
"

6. Verify audit file permissions (Unix only)

python -c "
import tempfile, stat, os
from pt_security_logger import SecurityLogger
with tempfile.TemporaryDirectory() as d:
    sl = SecurityLogger(log_dir=d)
    sl.log_auth_attempt('test', success=True)
    mode = oct(stat.S_IMODE(os.stat(sl._audit_path).st_mode))
    print('permissions:', mode)  # should be 0o600
    sl.close()
"

Expected on Unix: 0o600 (owner read/write only).

Rollback

git checkout main -- app/pt_security_logger.py app/test_security_logger.py

- Remove unused hashlib import - close(): make idempotent by clearing self._handler after shutdown - get_recent_events: guard limit <= 0 (deque maxlen rejects negatives); docstring corrected to reflect O(file_size) time / O(limit) memory - test_multiple_events_ordered: assert event_type append order (robust to clock adjustments) + non-decreasing timestamp sanity check

Ibrahim-3d · 2026-05-20T13:50:07Z

All 23 outstanding Copilot threads resolved. Round-1/2 threads (already replied inline) marked resolved; round-3 (5 new) addressed in commit 08dd045:

deque negative limit: get_recent_events now guards limit <= 0 and returns [] before constructing the deque.
docstring time complexity: corrected to O(file_size) time / O(limit) memory.
close() idempotent: handler reference cleared after shutdown; safe to call multiple times.
unused hashlib: removed.
non-monotonic timestamps in test: ordering now asserted on event_type sequence (robust to NTP/DST); non-decreasing timestamp kept as cheap sanity check.

All 30 test_security_logger tests pass locally. Ready for re-review.

Copilot review follow-up (commit `5f96c43`)

Merged main to clear the conflict and addressed all open threads:

#	File:Line	Issue	Resolution
1	pt_security_logger.py:50	`AUTH_ATTEMPT` defined but never emitted	Removed dead enum value; test repointed to `AUTH_SUCCESS`
2	pt_security_logger.py:close()	`close()` not synchronized with `_emit()`	`close()` now holds `self._lock` (same lock as `_emit`), stays idempotent
3	pt_security_logger.py:get_recent_events()	Malformed JSON lines silently dropped	Lines still skipped but counted and surfaced via `logger.warning`
4	pt_security_logger.py:log_system_event()	Docstring implied a closed event-type set	Docstring now states any `SecurityEventType` is accepted; examples illustrative
5	pt_security_logger.py:50	Duplicate of #1	Same fix
6	pt_security_logger.py:12	'extends pt_logging_system' vs standalone	Took main's wording (#98/#99); module documented as fully self-contained

Black + flake8 clean, 30 unit tests pass.

@sjackson0109 I have updated the PR description to correctly state that pt_security_logger is a standalone module and does not depend on pt_logging_system. I also updated the usage examples in the description to use CorrelationContext for consistency with the code. This addresses the documentation mismatch flagged by Copilot.
