- subtract_user_balance: only rollback when commit=True, re-raise when
commit=False so caller controls transaction lifecycle
- log_promo_offer_action: add db.flush() when commit=False to surface
constraint errors immediately instead of deferring to caller's commit
- 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`)
The admin endpoint wrote only to the legacy users.promo_group_id FK,
which got overwritten by sync_user_primary_promo_group on the next
transaction. Now writes to user_promo_groups M2M table (authoritative
source) and re-derives the FK via sync.
Also re-raise exceptions in _sync_user_primary_promo_group to prevent
committing inconsistent state between M2M and FK columns.
Without post_update, SQLAlchemy's flush ordering cannot resolve the
circular dependency when both a user and their referrer are in the same
session. This caused referred_by_id to be silently NULLed during flush,
breaking Telegram login (which eagerly loads User.referrer) and causing
apparent admin rights loss in the cabinet.
OAuth login was unaffected because it uses a bare select(User) without
eager loading the referrer relationship.
Root cause confirmed by 6 parallel investigation agents tracing the
exact code paths through get_user_by_telegram_id → selectinload →
flush → circular dependency.
- Remove estimated renewal price display from balance top-up screen
- Remove country name generation during server/squad sync, use original RemnaWave name as display_name
- Add html.escape() for all display_name/country name values rendered in HTML-parsed Telegram messages
Add a per-tariff visibility flag (show_in_gift) that controls whether
a tariff appears in the /gift section. Enforced server-side in gift
config query, gift purchase endpoint, and landing page gift purchases.
Includes Alembic migration with idempotency guard and server_default.
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
- Remove is_active_paid_subscription guard from reset-subscription endpoint
- Add is_trial=False and status=ACTIVE on admin tariff change (guarded by
tariff.is_trial_available and end_date check)
- Eagerly load user_promo_groups and promo_group in gift purchase locked query
- Move user_promo_groups access inside try/except in get_primary_promo_group()
- Stars: ceil → round в rubles_to_stars, нормализация kopeks в cabinet invoice
- Устройства/трафик: добавлен transaction_type в subtract_user_balance,
покупки устройств и трафика теперь создают SUBSCRIPTION_PAYMENT (не WITHDRAWAL),
что исправляет отображение в статистике продаж
1. Balance-mode gift purchase leaked full 64-char token in response.
Gateway path truncated to [:12] but balance path didn't. Fixed.
2. retry_stuck_pending_activation referenced GuestPurchase.updated_at
which doesn't exist on the model. Changed to paid_at (mirrors
retry_stuck_paid_purchases pattern).
3. clear_notifications() called db.commit() unconditionally, defeating
commit=False in replace_subscription. Added commit parameter with
default=True for backward compat, passed through from caller.
1. Truncate tokens to 12 chars in all API responses (SentGift,
PendingGift, ReceivedGift, PurchaseStatus, PurchaseResponse,
return URL) — full token no longer leaves the server
2. Status endpoint supports prefix-based token lookup
3. create_paid_subscription/replace_subscription accept commit=False
— activate_purchase now uses single atomic commit for subscription
+ purchase status update (fixes double-commit gap)
4. Bot handler uses flush() instead of commit() before svc_activate
— consistent with cabinet endpoint, allows rollback on failure
5. Add retry_stuck_pending_activation() for purchases stuck in
PENDING_ACTIVATION status (10 min threshold)
6. Add varchar_pattern_ops index for prefix queries on token column
- current_tier_name and is_current now determined by highest achieved
tier threshold instead of user's assigned promo group
- Backend update_promo_group converts threshold 0 to NULL for clean state
- Replace 501 stub with full gateway payment flow via PaymentService
- Move telegram username pre-check (DB-first) above gateway/balance branch
- Add recipient_warning column to GuestPurchase model + migration 0034
- Return warning in gift purchase status endpoint
- Add db.refresh(purchase) after commit in gateway branch
- Add source column (landing/cabinet) to track purchase origin
- Add buyer_user_id FK to link cabinet gift purchases to authenticated users
- Add GIFT_PAYMENT to TransactionType enum for balance deductions
- Add foreign_keys disambiguation to existing user relationship
- Migration 0032: adds columns, index on source, FK constraint
- 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)
- New gift_activation handler for gift_activate:{id} callback buttons
- Send Telegram notification to gift recipients with activate button
- Add skip_notification param to activate_purchase to prevent duplicates
- Fix telegram username regex minimum length (4→5 chars) in landing routes
- Add BOT_TOKEN guard in telegram gift notification sender
- Pre-resolve notification params before commit to avoid DetachedInstanceError
Migration 0001 uses Base.metadata.create_all() which creates ALL tables
from current models.py, causing subsequent migrations (0015+) to fail
with "already exists" errors when they try to re-create constraints,
indexes, columns, and tables.
Three-layer fix:
1. migrations.py: detect fresh DB (no tables) and bootstrap via
create_all() + stamp head, bypassing all migrations entirely.
2. models.py: add EmailTemplate model, CheckConstraints to LandingPage,
and indexes to GuestPurchase so create_all() produces a complete
schema identical to running all 30 migrations sequentially.
3. Idempotency guards in migrations 0015-0030: _has_unique_constraint,
_has_table, _has_index, _has_column, _has_check_constraint checks
before DDL operations, protecting against re-runs via make migrate.
Add time-bounded percentage discounts with per-tariff overrides
