CRITICAL fixes:
- promocode_service: NameError (subscription_id not passed), TypeError (dict
returns), savepoint without commit, dead else branch
- cabinet status/autopay/renewal: resolve_subscription() instead of
user.subscription fallback in multi-tariff mode
- cabinet devices: MultipleResultsFound crash on 3 POST endpoints
- webhook service: IDOR returning cross-user subscription
- monitoring_service: real expiring notification keyboard with se:{sub_id}
HIGH fixes:
- subscription_purchase_service: FOR UPDATE on both branches of submit_purchase
- miniapp: 8 endpoints now pass subscription_id to _ensure_paid_subscription
- inline.py: se:{subscription_id} callback for expiring keyboard
- tariff_purchase: TransactionType.FAILED_REFUND + _persist_failed_refund()
- account_merge_service: panel sync after subscription transfer
- webhook service: .limit(1) on fallback queries to prevent MultipleResultsFound
miniapp.py: get_subscription_details, get_tariffs, purchase_tariff,
preview_tariff_switch all resolve subscription from subscriptions list
instead of user.subscription property.
subscriptions.py + users.py: replace_existing and deactivation use
smart selection with len==1 guard.
- Add _resolve_panel_uuid helper for per-subscription UUID in multi-tariff mode
- Add user ownership validation (user_id check) to all subscription queries
- Add unique partial index on (user_id, tariff_id) for active subscriptions
- Generate remnawave_short_id for new subscriptions in all creation paths
- Fix trial endpoints to check all user subscriptions, not just first
- Fix channel member handler to enable/disable per-subscription UUIDs
- Fix channel checker middleware for multi-subscription iteration
- Fix tariff switch, traffic, and device endpoints to use correct panel UUID
- Fix monitoring, auto-purchase, renewal services for multi-subscription
- Fix user_service, miniapp, subscriptions and users webapi routes
- Add telegram_user_id and user_db_id to get_balance_payment_description() across
8 cabinet balance providers (heleket, mulenpay, pal24, wata, cloudpayments,
freekassa, kassa_ai, riopay), all miniapp endpoints, and recurrent payments
- For email/OAuth users without telegram_id, fallback to DB ID with (U{id}) format
- Fix pre-existing tuple bug in bot_configuration.py (trailing comma created tuple)
- Fix typo in nalogo_queue_service.py log message ("Чек уже попыток")
When a daily subscription is resumed after user deletion from RemnaWave panel
and deactivation sync, connected_squads were cleared but never restored,
causing internal squads to not be assigned. Also, admin notifications were
missing from the Telegram bot handler path.
Fixed across all 5 resume code paths:
- cabinet /pause endpoint
- miniapp /subscription/daily/toggle-pause endpoint
- bot handle_toggle_daily_subscription_pause handler
- DailySubscriptionService._process_single_charge
- try_resume_disabled_daily_after_topup auto-resume
Changes in each path:
- Restore connected_squads from tariff.allowed_squads (fallback: all available servers)
- Branch create/update based on remnawave_uuid presence
- Follow-up PATCH after POST to ensure internal squads are assigned
- Use limit=10000 in get_all_server_squads to avoid silent truncation
- Separate try/except for squad restore vs RemnaWave sync for resilience
- Add admin notification in bot handler (was missing)
lock_user_for_pricing with populate_existing=True was overwriting the
pending is_daily_paused mutation before db.commit(), silently discarding
the pause toggle. Fix moves lock before state reads, uses commit=False
for subtract_user_balance and create_transaction to ensure single atomic
commit, and re-applies is_daily_paused after any populate_existing reload.
Inactive tariffs with is_trial_available=True can now be used for trial
activation across bot, miniapp, and cabinet. This enables dedicated trial
tariffs with custom limits (traffic, devices, servers) without exposing
them in the regular purchase flow. Paid trial paths now properly resolve
trial tariff parameters instead of using global settings defaults.
Cabinet API and WebAPI created admin balance transactions with
payment_method=NULL instead of 'manual', making them invisible
to sales statistics filters.
Changes:
- Add payment_method=PaymentMethod.MANUAL to Cabinet and WebAPI
balance update endpoints
- Add func.abs() to all transaction amount aggregations missing it
across sales stats, dashboard stats, and reporting queries
- Remove redundant Python abs() on addon_revenue (SQL func.abs
already applied)
- Add data migration 0044 to fix historical NULL payment_method
records for admin top-ups
Replace all ~45 direct Bot() calls across the codebase with a centralized
create_bot() factory function that automatically configures SOCKS5 proxy
session when PROXY_URL is set. This ensures proxy support applies uniformly
to all Telegram API traffic.
Key changes:
- Add app/bot_factory.py with create_bot() factory
- Replace direct Bot() instantiation in 33 files
- Fix session leaks in cloudpayments.py and auth.py (async with)
- Replace 2 direct httpx calls to api.telegram.org with
bot.create_invoice_link() (balance.py, wheel.py)
- Remove now-unused imports (Bot, DefaultBotProperties, ParseMode, httpx)
Previously the bot showed only one referral link (cabinet when CABINET_URL
is set, bot otherwise). Users who received the cabinet link were confused —
they opened a web registration form instead of being directed to the bot.
Now the bot, cabinet API, and miniapp API all return both links:
- Bot link (t.me deep link) — always shown
- Cabinet link (web registration) — shown when CABINET_URL is configured
Changes:
- Add get_bot_referral_link() and get_cabinet_referral_link() to config
- Refactor config methods to eliminate code duplication
- Update bot referral handler to display both links
- Fix switch_inline_query 256-char limit with auto-truncation
- Add html_escape() to all user-controlled strings in HTML messages
- Add translations for 5 new keys in all 5 locale files (ru/en/ua/zh/fa)
- Simplify cabinet route to use new methods instead of inline URL construction
- Add bot_referral_link to MiniApp API schema and response
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.
