Implement automatic token refresh mechanism for CPA providers (Codex,
GeminiCLI, Antigravity, ClaudeCode) with the following features:
- Periodic refresh of expiring tokens based on configurable interval
- Redis event queue processing for on-demand token refresh
- Retry logic with exponential backoff for transient failures
- Automatic key deactivation on non-retryable errors
- Provider-specific OAuth token refresh implementations
- Sync service integration to update providers after refresh
Add support for OAuth-based authentication with access/refresh tokens
and expiration tracking for API keys. Extend provider groups with
static headers configuration and headers profile options.
Changes include:
- Add AccessToken, RefreshToken, ExpiresAt, AccountID, ProjectID to APIKey model
- Add StaticHeaders and HeadersProfile to ProviderGroup model
- Add TokenRefresh configuration for background token management
- Support new provider types: ClaudeCode, Codex, GeminiCLI, Antigravity
- Update sync service to include new fields in provider snapshots
Replace health_handler with status_handler providing public /status and
/about endpoints. Add build-time version injection via ldflags in
Makefile, and support --version/-v CLI flag.
- Add /status endpoint returning runtime status, uptime, and version
- Add /about endpoint with system metadata (name, description, repo)
- Configure VERSION variable with git describe fallback
- Update swagger docs and api.md for new public endpoints
- Remove deprecated /api/status/test endpoint
Use UnixNano for version field while keeping Unix seconds for updated_at
timestamp. This ensures version changes are detected even when multiple
syncs occur within the same second.
Add new response types and parameters for logs API:
- Add GroupedStatsItem and GroupedStatsResponse definitions
- Add ListLogsResponse and LogView definitions for detailed log records
- Add group_by enum parameter (model/day/month) to stats endpoint
- Update endpoint descriptions to clarify response types and request_body inclusion
- Update response schema references to use correct types
Add group_by parameter to /admin/logs/stats endpoint supporting:
- group_by=model: aggregate stats per model with avg latency
- group_by=day: daily aggregation with token counts
- group_by=month: monthly aggregation with token counts
Also include request_body field in admin ListLogs response for
full visibility into logged requests.
- Introduce `SyncOutboxService` and model to retry failed CP-to-Redis sync operations
- Update `SyncService` to handle sync failures by enqueuing tasks to the outbox
- Centralize provider group and API key validation logic into `ProviderGroupManager`
- Refactor API handlers to utilize the new manager and robust sync methods
- Add configuration options for sync outbox (interval, batch size, retries)
- Update TestBatchBindings_Status to use newTestHandlerWithRedis helper
- Remove unused jsonID helper function from sync_bindings_spec_test.go
- Add time import to models.go
Restructure the provider management system by separating the monolithic
Provider model into two distinct entities:
- ProviderGroup: defines shared upstream configuration (type, base_url,
google settings, models, status)
- APIKey: represents individual credentials within a group (api_key,
weight, status, auto_ban, ban settings)
This change also updates:
- Binding model to reference GroupID instead of RouteGroup string
- All CRUD handlers for the new provider-group and api-key endpoints
- Sync service to rebuild provider snapshots from joined tables
- Model registry to aggregate capabilities across group/key pairs
- Access handler to validate namespace existence and subset constraints
- Migration importer to handle the new schema structure
- All related tests to use the new model relationships
BREAKING CHANGE: Provider API endpoints replaced with /provider-groups
and /api-keys endpoints; Binding.RouteGroup replaced with Binding.GroupID
Introduce a new `import` subcommand to the server binary that reads
exported JSON files and imports masters, providers, keys, bindings,
and namespaces into the database.
Key features:
- Support for dry-run mode to validate without writing
- Conflict policies: skip existing or overwrite
- Optional binding import via --include-bindings flag
- Auto-generation of master keys with secure hashing
- Namespace auto-creation for referenced namespaces
- Detailed import summary with warnings and created credentials
Introduce StatsService integration to admin and master handlers,
exposing realtime metrics (requests, tokens, QPS, rate limit status)
via new endpoints:
- GET /admin/masters/:id/realtime
- GET /v1/realtime
Also embed realtime stats in the existing GET /admin/masters/:id
response and change GlobalQPS default to 0 with validation to
reject negative values.
Implement webhook notifications for log error threshold alerts with
configurable thresholds, time windows, and cooldown periods.
- Add LogWebhookService with Redis-backed configuration storage
- Add admin endpoints for webhook config management (GET/PUT)
- Trigger webhook notifications when error count exceeds threshold
- Support status code threshold and error message detection
- Include sample log record data in webhook payload
Add runtime feature flag to control whether request bodies are stored
in logs. The Handler now accepts a Redis client to check the
log_request_body_enabled feature flag before persisting log records.
- Add logRequestBodyFeatureKey constant for feature flag
- Inject Redis client into Handler for feature flag lookups
- Strip request body from log records when feature is disabled
- Update tests to pass Redis client to NewHandler
Add tests for UpdateFeatures endpoint covering:
- Regular feature flag keys with various value types
- Mixed keys combining feature flags with log retention settings
- Redis storage verification for both scenarios
Add special handling for log_retention_days and log_max_records features
that are stored as separate Redis keys instead of in the features hash.
- Store log overrides in dedicated keys (meta:log:retention_days,
meta:log:max_records) for runtime access by log cleanup cron
- Include log override values in ListFeatures response
- Support clearing overrides by setting value to 0
- Add comprehensive tests for log override CRUD operations
Implement LogCleaner cron job to automatically clean up old log records
based on configurable retention period and maximum record count.
- Add LogCleaner with retention_days and max_records configuration
- Add EZ_LOG_RETENTION_DAYS and EZ_LOG_MAX_RECORDS environment variables
- Default to 30 days retention and 1,000,000 max records
- Include unit tests for log cleaner functionality
- Add `POST /admin/providers/preset` for streamlined creation of official providers (OpenAI, Anthropic, Gemini)
- Add `POST /admin/providers/custom` for generic OpenAI-compatible providers
- Add `weight` field to provider model and DTOs to enable weighted routing
- Update sync service to propagate provider weights
- Add unit tests for new creation handlers
Add unit tests for the SyncBindings service covering exact matching,
regex selectors, and normalized matching logic using in-memory
dependencies (SQLite and MiniRedis) to ensure correct upstream
resolution.
Add endpoints for master and key access management to configure default
and allowed namespaces, including propagation options.
Implement GET and DELETE operations for individual bindings.
Update sync service to persist bindings snapshots even when no upstreams
are available.
Standardize alignment of struct tags in models and field assignments in
services for better readability. Additionally, include the Binding model
in the test database auto-migration.
Implement handlers for creating, listing, and updating model bindings.
Register new routes in the admin server group and add DTO definitions.
Update provider handlers to trigger binding synchronization on changes
to ensure upstream mappings remain current.
Introduce namespace-aware routing capabilities through a new Binding
model and updates to Master/Key entities.
- Add Binding model for configuring model routes per namespace
- Add DefaultNamespace and Namespaces fields to Master and Key models
- Update auto-migration to include Binding table
- Implement Redis synchronization for binding configurations
- Propagate namespace settings during master creation and key issuance
Add `POST /admin/masters/{id}/keys` allowing admins to issue child keys
on behalf of a master. Introduce an `issued_by` field in the Key model
to audit whether a key was issued by the master or an admin.
Refactor master service to use typed errors for consistent HTTP status
mapping and ensure validation logic (active status, group check) is
shared.
Add FeatureHandler to manage lightweight runtime configuration toggles
stored in the Redis `meta:features` hash. This enables dynamic control
over system behavior (e.g., storage backends) via the admin API.
- Add `GET /admin/features` to list flags
- Add `PUT /admin/features` to update flags
- Update README with feature flag documentation
- Update TESTING.md to reflect current testing status and future plans
- Add golden file comparison for provider snapshot validation in sync_test.go
- Introduce master_test.go for testing Master/Key functionality
- Add testdata directory for contract testing snapshots
Introduce a middleware layer to attach a unique identifier to each HTTP request for observability purposes. The identifier is propagated via the X-Request-ID header, allowing for correlation of logs and events across distributed system components.
