The old code hashed the full raw body INCLUDING the 'signature' field
itself — a circular computation that can never match (you can't include
the signature in the data being signed).
Fix:
1. Strip 'signature' key from payload before HMAC-SHA256 computation
2. Try both sorted and unsorted keys (PayPear docs don't specify)
3. Fallback to IP allowlist check (158.160.85.101 per PayPear docs)
4. Pass client_ip from request headers to the verification function
- Replace fail-open with fail-closed in CryptoBot, Heleket, Tribute webhooks
(missing API key now rejects instead of accepting)
- Use hmac.compare_digest for timing-safe comparison in Freekassa, KassaAI,
Pal24, and Platega webhook verification
- CloudPayments: reject webhooks when signature header is missing but
API_SECRET is configured (check, pay, fail, universal endpoints)
- CloudPayments: return code 13 (reject) instead of code 0 on parse errors
and exception handlers to prevent fail-open
Platega: handle verification ping POST without auth headers (empty body → 200 OK)
CryptoBot: always use API token for signature verification per docs, not WEBHOOK_SECRET
CryptoBot: reject requests without signature in both FastAPI and aiohttp handlers
Remove dead self.webhook_secret from CryptoBotService
Update tests to match new behavior
- Use API token as fallback for webhook signature verification per CryptoBot docs
- Try raw body, re-serialized compact JSON, and ASCII-escaped JSON for signature matching
- Auto-fill payment amount from saved cart in show_payment_methods instead of hardcoded 0
- API клиент (HMAC-SHA256 подпись, создание/получение платежа)
- CRUD операции с FOR UPDATE блокировкой
- Payment mixin с обработкой webhook и финализацией
- Хендлеры бота для пополнения через SeverPay
- Миграция 0040: таблица severpay_payments
- Webhook endpoint (всегда 200 для предотвращения ретраев)
- Интеграция с payment_verification_service
- Поддержка гостевых покупок (лендинги, подарки)
- SELECT FOR UPDATE блокировка во всех 9 провайдерах (кроме YooKassa — свой паттерн)
- create_transaction(commit=False) + единый db.commit() для атомарности
- emit_transaction_side_effects() для отложенных событий после коммита
- Все link_*_payment_to_transaction используют db.flush() вместо db.commit()
- Freekassa/KassaAI: прямое присвоение transaction_id + flush вместо update_status
- MulenPay: прямая мутация balance_kopeks вместо add_user_balance
- Platega: блокировка перед чтением metadata, инлайн обновления полей
- CloudPayments: int(round(amount * 100)) для корректного округления
- Heleket добавлен в SUPPORTED_AUTO_CHECK_METHODS
- Удалены PII из логов yookassa webhook (заголовки, IP)
- UniqueConstraint(external_id, payment_method) на транзакциях + миграция 0017
- Cabinet: PaymentService(bot=bot) внутри try блока
- verify_payment_amount утилита для проверки суммы webhook
- Add ContextVarsMiddleware for automatic user_id/chat_id/username binding
via structlog contextvars (aiogram) and http_method/http_path (FastAPI)
- Use bound_contextvars() context manager instead of clear_contextvars()
to safely restore previous state instead of wiping all context
- Register ContextVarsMiddleware as outermost middleware (before GlobalError)
so all error logs include user context
- Replace structlog.get_logger() with structlog.get_logger(__name__) across
270 calls in 265 files for meaningful logger names
- Switch wrapper_class from BoundLogger to make_filtering_bound_logger()
for pre-processor level filtering (performance optimization)
- Migrate 1411 %-style positional arg logger calls to structlog kwargs
style across 161 files via AST script
- Migrate log_rotation_service.py from stdlib logging to structlog
- Add payment module prefixes to TelegramNotifierProcessor.IGNORED_LOGGER_PREFIXES
and ExcludePaymentFilter.PAYMENT_MODULES to prevent payment data leaking
to Telegram notifications and general log files
- Fix LoggingMiddleware: add from_user null-safety for channel posts,
switch time.time() to time.monotonic() for duration measurement
- Remove duplicate logger assignments in purchase.py, config.py,
inline.py, and admin/payments.py
- tickets.py: guard against non-text messages in waiting_for_title FSM state
- payments.py: fix Wata webhook using wrong field name (order_id vs orderId),
add full payload to error log
- tariff.py: stop overwriting admin tariff settings on every bot restart,
sync_default_tariff_from_config now only creates if no tariff exists
- start.py: catch TelegramBadRequest specifically for "message is not modified"
instead of bare except with useless retry
- admin/tickets.py: downgrade ticket notification log from error to warning
for expected case of OAuth/email users without telegram_id
- pricing.py, countries.py, purchase.py: guard against expired FSM state
causing KeyError on 'period_days'
- blacklist_service.py: add 5-min in-memory cache to is_user_blacklisted()
to reduce DB load from per-request checks
- remnawave_service.py: fix "Session is closed" race condition — create
new RemnaWaveAPI instance per get_api_client() call instead of reusing
shared instance whose aiohttp session gets overwritten by parallel coroutines
- Add pyproject.toml with uv and ruff configuration
- Pin Python version to 3.13 via .python-version
- Add Makefile commands: lint, format, fix
- Apply ruff formatting to entire codebase
- Remove unused imports (base64 in yookassa/simple_subscription)
- Update .gitignore for new config files
