Previously, users could retain access to servers removed from their
promo group by re-submitting already-connected UUIDs in country
selection requests. The validation allowed any UUID present in
current connected_squads, bypassing promo group checks.
Now all selected server UUIDs must be in the user's allowed promo
group set. Unauthorized servers are rejected (cabinet/bot) or
filtered out (miniapp). Fixes authorization bypass across all 3
surfaces: cabinet, Telegram bot, and miniapp.
When sync_squads parameter was introduced (4aaf0ddd) to prevent FK
violations from stale squad UUIDs, all update_remnawave_user calls
defaulted to sync_squads=False. This broke squad synchronization for
purchase/tariff-change flows where squads are freshly assigned and
must be sent to the panel.
Adds sync_squads=True to all purchase, tariff switch, and country
selection call sites across cabinet, bot handlers, miniapp, and
auto-purchase service.
- Add SubscriptionStatus.LIMITED for traffic-exhausted subscriptions
- Webhook user.limited now sets LIMITED directly instead of DISABLED
- Add LIMITED to reactivation, extend, resume, auto-purchase, contest eligibility
- Add traffic_exhausted error response in miniapp API
- Fix device_limit being overwritten on tariff switch in all code paths:
admin change_tariff, user switch-tariff, miniapp, bot tariff_purchase,
auto_purchase_service — now preserves extra purchased devices via
calc_device_limit_on_tariff_switch() helper
- Fix truthiness checks on device_limit (0 is valid, use `is not None`)
Centralized referral link generation into settings.get_referral_link().
When CABINET_URL is configured, links use {CABINET_URL}?ref={code}.
Falls back to Telegram bot deep link when CABINET_URL is not set.
- URL-encodes referral_code for safety
- Handles CABINET_URL with existing query params (uses & vs ?)
- Guards against None referral_code in all call sites
- QR code caching uses link hash for auto-invalidation
When traffic is exhausted, RemnaWave may send user.expired webhook setting
local status to EXPIRED (not just DISABLED). reactivate_subscription() only
handled DISABLED→ACTIVE, silently ignoring EXPIRED subscriptions. After
purchasing additional GB, the subscription stayed expired and VPN remained
blocked despite payment.
Changes:
- reactivate_subscription() now handles both DISABLED and EXPIRED→ACTIVE
when end_date is still in the future
- Inverted null end_date guard to block reactivation (defense-in-depth)
- Added enable_remnawave_user() call after update in all traffic/device
top-up paths to ensure panel exits LIMITED state
- Gated enable call on subscription.status == 'active' to prevent
enabling when reactivation was a no-op
- Fixed all 12 call sites across bot handlers, cabinet routes,
miniapp, webapi, and auto-purchase service
- Add transaction records for free tariff switches (downgrade, upgrade_cost=0) in miniapp and cabinet
- Add atomic transaction records for admin tariff changes in bot handler and cabinet API
- Use commit=False for admin flows to ensure subscription change and transaction are committed together
1. Admin notification showed "renewal" instead of "first purchase" for new
users because has_had_paid_subscription was set before notification.
All 21 call sites now pass explicit purchase_type.
2. Partner referral not counted when mandatory channel subscription enabled.
required_sub_channel_check saved campaign_id but not referrer_id from
campaign.partner_user_id. Also removed duplicate DB query.
3. BOT_USERNAME auto-detection moved before web server start to close
race window on /cabinet/branding/telegram-widget endpoint.
- YooKassa: return local_payment_id instead of UUID for frontend polling
(parseInt on UUID produced wrong ID → eternal spinner)
- PAL24: remove unsupported payment_method param from API call
(cabinet and miniapp routes — URL selection is client-side)
The miniapp, legacy cabinet endpoint, auto-purchase service, and Telegram bot
handlers were using only global settings (PRICE_PER_DEVICE, MAX_DEVICES_LIMIT)
for device purchases, completely ignoring tariff-level device_price_kopeks and
max_device_limit. This allowed users to buy devices when tariff price was 0
(should be blocked) and exceed the tariff's max device limit.
Fixed in all 4 code paths:
- miniapp _build_subscription_settings + update_subscription_devices_endpoint
- cabinet legacy POST /devices (+ added subscription status check, RemnaWave sync)
- subscription_auto_purchase_service._auto_add_devices
- telegram bot handlers confirm_change_devices, execute_change_devices, confirm_add_devices
- Add try_resume_disabled_daily_after_topup() for instant resume when balance is topped up
- Fix all 5 resume paths to charge daily fee BEFORE activating subscription
- Remove unsafe inline auto-resume from add_user_balance() that bypassed fee charging
- Add NULL-safe is_daily_paused filter in subscription queries
- Use create_remnawave_user() instead of enable_remnawave_user() for full VPN panel sync
- Add DAILY_SUBSCRIPTION_RESUMED_AFTER_TOPUP localization key (ru, en, fa, zh, ua)
The guard silently blocked admins from deactivating active paid
subscriptions, returning a generic error with no explanation.
Admin deactivation is intentional (with confirmation step) and
should not be prevented. The guard remains in automated processes
(monitoring, broadcast, user_service) where it makes sense.
The security hardening commit changed allow_headers from ['*'] to
['Authorization', 'Content-Type'], but the frontend sends X-CSRF-Token
on all POST/PUT/DELETE/PATCH requests and X-Telegram-Init-Data on all
requests. The missing headers caused preflight OPTIONS requests to fail
with 400 "Disallowed CORS origin".
- Revert OIDC flush to commit before _store_refresh_token
(matches widget/initData pattern, prevents rollback losing user updates)
- Fix CORS wildcard+credentials in webapi/app.py (same as unified_app fix)
- 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
Когда RemnaWave ставит пользователю статус LIMITED (трафик исчерпан),
webhook бота устанавливает локальный статус подписки в DISABLED. При
покупке дополнительного трафика update_remnawave_user() видел DISABLED
и отправлял status=EXPIRED, что RemnaWave отвергал с ошибкой 400.
Добавлен вызов reactivate_subscription() перед синхронизацией с RemnaWave
во всех 8 потоках покупки/переключения трафика:
- handlers/subscription/traffic.py (add_traffic, execute_switch_traffic)
- cabinet/routes/subscription.py (purchase_traffic)
- cabinet/routes/admin_users.py (admin add_traffic)
- handlers/admin/users.py (_add_subscription_traffic)
- webapi/routes/miniapp.py (purchase_traffic_topup)
- subscription_auto_purchase_service.py (_auto_add_traffic, _auto_add_devices)
Также разрешён статус DISABLED в guard автопокупки трафика и устройств,
чтобы LIMITED пользователи могли автоматически докупать ресурсы.
- Убран WITHDRAWAL из автонегации в create_transaction (ломал profit,
expenses и display flip в admin_users)
- Добавлен func.abs() в by_type агрегацию (transaction.py)
- Добавлен func.abs() в total_spent user.py (_build_spending_stats_select)
- Исправлен all_time_stats в боте и webapi: передаём явный диапазон дат
вместо дефолтного текущего месяца
- Добавлен abs() на уровне API-ответов для subscription_income (защита от
негативных значений при несогласованных знаках SUBSCRIPTION_PAYMENT)
- Нормализация знаков в create_transaction: SUBSCRIPTION_PAYMENT и WITHDRAWAL
всегда сохраняются как отрицательные (дебет)
- Исправлен income_total в дашборде: показывал месячный доход вместо общего
(теперь используется отдельный запрос all_time_stats)
Add SELECT FOR UPDATE row lock on subscription before checking device
limit in all 3 device purchase endpoints (cabinet new, cabinet legacy,
miniapp). Without the lock, two concurrent requests both read the old
device_limit, both pass validation, and both increment — resulting in
device count exceeding max_device_limit (e.g., 5 devices when limit is 3).
Also moved max-devices check before balance check in legacy endpoint
to fail fast under lock.
- Add consume_promo_offer to 5 call sites in tariff_purchase.py where
_get_user_period_discount() stacks promo_offer into blended discount
(lines 823, 1134, 1706, 2238, 2971)
- Fix negative amount_kopeks in miniapp.py:5351 transaction record
(was -final_total, all other SUBSCRIPTION_PAYMENT use positive)
- Replace duplicate _get_user_promo_offer_discount_percent in
monitoring_service with shared get_user_active_promo_discount_percent
The tariff-mode renewal in miniapp applied promo_offer_discount_percent
to final_total but never passed consume_promo_offer to subtract_user_balance,
allowing infinite reuse of first-purchase-only promo discounts via miniapp.
SUBSCRIPTION_DAYS promo codes now require an active or expired non-trial
subscription. Users without any subscription or with a trial subscription
get a clear error message instead of silently creating/extending.

Add is_active_paid_subscription() helper that checks if subscription is
non-trial, active, and not expired. Use it across all disable_remnawave_user
call sites to prevent disabling VPN access for users with paid subscriptions.
Protected paths: block_user, delete_user_account, broadcast cleanup,
channel unsubscribe, admin deactivation, webapi endpoints, cabinet
reset-trial, reset-subscription, and disable-user endpoints.
- 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)

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
