- Default balance_low_enabled changed to False (opt-in via cabinet)
- Quiet hours: alerts skipped between 22:00-09:00 UTC
- Only alerts when subscription expires within LOW_BALANCE_ALERT_EXPIRY_DAYS (default 3)
- Added inline "Top up" button linking to cabinet miniapp
- Synced defaults across notification_prefs, cabinet notifications route
Show each Platega method (SBP, cards, crypto) as a separate button
on the main payment screen like YooKassa, instead of behind a sub-menu.
Controlled by PLATEGA_INLINE_METHODS env var (default: true).
Set to false to keep the old sub-menu behavior.
Bot uses default HTML parse mode — all messages are HTML-parsed by Telegram.
Added html.escape() to all user-controlled and admin-controlled strings
before interpolation into HTML messages to prevent injection and parse errors.
49 files, ~250+ injection points fixed:
- user.full_name, first_name across all handlers and services
- tariff.name/description in purchase flow, admin panel, auto-purchase service
- campaign.name, start_parameter in admin and user-facing handlers
- group.name, promo_group.name across promo management
- contest.title, prize_text, leaderboard names (including public channels)
- transaction.description (contains raw user.full_name from referral service)
- restriction_reason across all balance and subscription handlers
- ticket.title, message_text, poll.title, poll.description
- welcome text template placeholders (first_name, username)
- maintenance reason, admin_name, selected_prize.display_name
New helpers in app/utils/formatting.py:
- safe_html_name() for escaping display names
- user_html_link() replacing 15+ duplicated inline link patterns
- Reorder middleware: LoggingMiddleware now outermost, GlobalErrorMiddleware inside — prevents full traceback logging for suppressed errors (message not modified, query too old, bot blocked)
- Fix root cause in message_patch.py: _edit_with_photo missing try/except for _original_edit_text when ENABLE_LOGO_MODE=False
- Add "message is not modified" suppression in AuthMiddleware to prevent unnecessary db.rollback() and ERROR-level logging
- Fix discount promo display in admin notifications: subscription_days shown as hours (not days), balance_bonus_kopeks shown as percentage (not price)
- Apply sanitize_proxy_error() to all 8 error handlers in nalogo_service
- Remove exc_info=True from error paths that could expose proxy creds
- Fix regex backreference to preserve original SOCKS scheme
- Consolidate proxy utility imports to module level
- Add source indicator (NALOGO_PROXY_URL vs fallback) to startup log
Route all nalog.ru API traffic through SOCKS proxy. Uses NALOGO_PROXY_URL
env var (falls back to PROXY_URL if not set). Adds httpx[socks] dependency.
- Thread proxy_url through Client → AuthProviderImpl + AsyncHTTPClient
- Extract mask_proxy_url() and sanitize_proxy_error() utilities
- Add socks5h:// scheme support for remote DNS resolution
- Sanitize proxy credentials in error messages
- Log masked proxy URL at startup and service init
- acquire FOR UPDATE lock immediately after payment lookup, before is_paid check
- use populate_existing=True to prevent SQLAlchemy identity map stale reads
- replace intermediate update_platega_payment(commit) with inline assignments + flush
- re-check locked.is_paid after lock in get_platega_payment_status
- guard _finalize_platega_payment: only called when lock held and is_paid=False
- suppress "message is not modified" TelegramBadRequest in message_patch
4 endpoints for referral network analysis: full graph with batched
aggregation queries, user detail with recursive CTE branch counting,
campaign detail with conversion metrics, and search with LIKE escaping.
All endpoints rate-limited, scoped queries to prevent full-table scans,
depth-limited recursive CTE, fail_closed on expensive graph endpoint.
Added selectinload(UserPromoGroup.promo_group) nested under
user_promo_groups to prevent lazy-load in get_primary_promo_group().
Added selectinload(User.referrer) for format_referrer_info().
Broadened except clause in format_referrer_info as safety net.
apply_percentage_discount now delegates to PricingEngine.apply_discount
(floor division). Removes ruble-rounding that caused inconsistency between
first-purchase and renewal pricing.
subscription_purchase_service._apply_percentage_discount now delegates
to the shared apply_percentage_discount.
All 60+ callers across handlers, keyboards, cabinet, miniapp, balance
automatically use the unified algorithm without code changes.
- Migrate bot purchase handlers, menu, admin users to PricingEngine
- SubscriptionRenewalService.finalize() accepts both old and new pricing types
- Remove dead subscription CRUD pricing functions (get_subscription_renewal_cost etc.)
- Remove dead pricing_utils functions
- Add menu_layout_cache.py for CABINET_MENU_LAYOUT in-process cache
- Add admin_menu_layout.py routes (GET/PUT/POST reset) with merged view
- Rewrite _build_cabinet_main_menu_keyboard to use cached row layout
- Support custom URL buttons with style, emoji, labels, enabled toggle
- Atomic dual-key DB writes for layout + button styles
- Add language button to default layout and DEFAULT_BUTTON_STYLES
- Pydantic validation with Literal types, max_length, duplicate ID checks
- Register routes and cache loading in bot startup
Replace hardcoded raw HTML length checks (len(text) <= 900/1000/1024)
with centralized caption_exceeds_telegram_limit() that strips HTML tags
and unescapes entities before measuring against the real 1024-char limit.
Fixes logo disappearing when promo discounts add HTML markup to captions.
- Quick amount buttons now calculate full renewal cost (base + devices + servers + traffic with discounts)
- Tariff mode uses tariff-specific device pricing (device_price_kopeks, device_limit)
- Broadcast inline buttons no longer crash with "no text in message to edit" on photo/video messages
- Media messages are now handled in _edit_with_photo: delete old message + send new text
- 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
- trial подписки теперь конвертируются в платные вместо отказа (ошибка ~20 из 300 юзеров)
- extend_subscription: добавлен переход TRIAL→ACTIVE
- UniqueConstraint на PromoCodeUse(user_id, promocode_id) + миграция 0015 с дедупликацией
- create_promocode_use: begin_nested()+flush() вместо commit/rollback (без коррупции сессии)
- race condition: create_promocode_use вызывается ДО _apply_promocode_effects
- cleanup: удаление зарезервированной записи при ValueError от эффектов
- atomic SQL increment для current_uses (защита от lost-update)
- mark_user_as_had_paid_subscription: savepoint вместо commit/rollback
- удалён мёртвый код: use_promocode(), trial_subscription_not_eligible из маппингов
import redis.exceptions overwrites the redis name binding from
import redis.asyncio as redis, causing from_url() to create a
sync client. ping() then returns bool instead of coroutine.
Fix: from redis.exceptions import NoScriptError
VK deprecated oauth.vk.com on Sep 30, 2025. Migrate to VK ID (id.vk.ru)
with mandatory PKCE S256 and device_id support.
- Rewrite VKProvider: new endpoints, PKCE code_verifier/challenge, user_info format
- Add prepare_auth_state() hook for provider-specific state (PKCE)
- Use atomic Redis GETDEL for OAuth state validation (prevent TOCTOU race)
- Add CacheService.getdel() method
- Check cache.set() result in generate_oauth_state
- Filter ephemeral keys (_prefix) from Redis storage
- Fix garbled log messages, use exc_info for tracebacks
- Add input validation (min_length, max_length on code/state)
- Generic error messages (no provider name leakage)
- Fix balance history display: referral_reward, refund, poll_reward now
shown as credits (💰 +amount) instead of expenses
- Fix double-counting: remove all Transaction-based REFERRAL_REWARD sum
queries from crud/referral.py, admin_stats.py, admin_users.py —
ReferralEarning is now the single source of truth
- Unify "active referrals" definition across cabinet, bot, and admin:
JOIN Subscription WHERE status=ACTIVE AND end_date > now()
- Add payment_method IS NOT NULL guard to get_user_own_deposits() to
exclude referral rewards historically mistyped as deposits
- Replace hardcoded transaction type strings with TransactionType enum
values in referral_withdrawal_service.py
- Add Alembic data migration (0014) to fix historical transactions:
UPDATE deposit → referral_reward WHERE payment_method IS NULL and
description matches referral patterns
1. Remove pointless HWID reset during auto-sync deactivation — user
doesn't exist in panel, API returns 404, UUID is cleaned up below.
2. Clean up RESTRICT FK references (AdminAuditLog, WithdrawalRequest,
AdminRole, UserRole, AccessPolicy) before deleting user to prevent
IntegrityError on admin_audit_log_user_id_fkey.
3. Fix device limit not being sent to RemnaWave when
DEVICES_SELECTION_DISABLED_AMOUNT=0: treat 0 as "no forced override"
instead of sending hwidDeviceLimit:0 (which Remnawave interprets as
unlimited). Now falls through to subscription.device_limit from tariff.
4. Add info-level logging to POST /api/users (was debug) to match
existing PATCH logging for device limit diagnostics.
- Multi-channel subscription enforcement via middleware, events, and cabinet API
- 3-layer cache architecture: Redis -> PostgreSQL -> rate-limited Telegram API
- ChatMemberUpdated event-driven tracking with automatic VPN access control
- Admin management via bot FSM handler and REST API with full CRUD
- Channel ID normalization: @username resolved to numeric ID at creation time
- Fail-closed error handling: API errors deny access (security-first)
- Background reconciliation with keyset pagination (100 per batch)
- Per-user rate limiting on subscription check button (5s cooldown)
- Redis connection pooling via cache singleton (no per-request connections)
- Database: channel_id index, multi-row upsert optimization
- Localization: en, ru, zh, fa, ua translations for all new strings
- Frontend blocking UI with channel list and subscription status
- Admin channel management page with toggle, delete, and create
When ENABLE_LOGO_MODE is on, messages are sent as photos which
naturally don't show URL previews. When off, messages are sent as
text but disable_web_page_preview was never set, causing link
previews in menu, welcome, and other messages.
Always patch Message.answer/edit_text and inject
disable_web_page_preview=True for all text message paths.
1. Add _prefix_logger_name processor that moves [module.name] before
event text for consistent format: timestamp [level] [module] message
2. Fix startup summary table alignment by using display width calculation
instead of len() — properly accounts for wide emoji and variation
selectors that render as 2 terminal cells
- 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
