- Add OnDefault rule type that matches when no other rules match
- Add validation to prevent multiple default rules
- Fix typo: extension → extensions in route config JSON tag
Enhanced the ConvertSlice function to include validation for destination slices that implement the CustomValidator interface. If validation fails, errors are collected and returned, ensuring data integrity during slice conversion.
The icon fetching logic now checks if the target service is healthy before
attempting to fetch icons. If the health monitor reports an unhealthy status,
the function returns HTTP 503 Service Unavailable instead of proceeding.
Additionally, the icon cache lookup now includes infinite retry logic with a
15-second backoff interval, improving resilience during transient service
outages. Previously, failed lookups would not be retried.
The `route` interface was extended with a `HealthMonitor()` method to support
the health check functionality.
* **New Features**
* Multiplexed TLS port: HTTP API and a custom stream protocol can share one port via ALPN.
* Agent-side TCP and DTLS/UDP stream tunneling with health-check support and runtime capability detection.
* Agents now advertise per-agent stream support (TCP/UDP).
* **Documentation**
* Added comprehensive stream protocol documentation.
* **Tests**
* Extended integration and concurrency tests covering multiplexing, TCP/UDP streams, and health checks.
* **Chores**
* Compose/template updated to expose both TCP and UDP ports.
- Added information about the loading page (HTML + JS + CSS) and the SSE endpoint for wake events.
- Clarified the health monitor implementation and readiness tracking in the architecture overview.
- Correct state machine syntax.
- Correct BaseContext nil check in Context() method
- Move NewMonitor from monitor.go to new.go
- Export ErrDockerHealthCheckFailedTooManyTimes and add ErrDockerHealthCheckNotAvailable
- Return ErrDockerHealthCheckNotAvailable when container has no health check configured
- Only log first docker health check failure and skip logging for ErrDockerHealthCheckNotAvailable
- Use mon.Context() instead of mon.task.Context() to avoid nil panic
- Move health check implementations from monitor/ to new check/ package
- Add h2c, tcp4/6, udp4/6 scheme support to agent health check API
- Add timeout URL parameter to agent health check endpoint
- Remove unused agent dependencies (dnsproviders, lego, various cloud SDKs)
- Use net.JoinHostPort instead of fmt.Sprintf for port joining
Moved non-agent-specific logic from agent/pkg/agent/ to internal/agentpool/:
- pool.go: Agent pool management (Get, Add, Remove, List, Iter, etc.)
- http_requests.go: HTTP utilities (health checks, forwarding, websockets, reverse proxy)
- agent.go: Agent struct with HTTP client management
This separates general-purpose pool management from agent-specific configuration,
improving code organization and making the agent package focused on agent config only.
- Introduced a new `Bind` field in the route configuration to specify the address to listen on for TCP and UDP routes.
- Defaulted the bind address to "0.0.0.0" if not provided.
- Enhanced validation to ensure the bind address is a valid IP.
- Updated stream initialization to use the correct network type (tcp4/tcp6 or udp4/udp6) based on the bind address.
- Refactored stream creation functions to accept the network type as a parameter.
- Introduced a new method `GetCertInfos` to fetch details of all available certificates.
- Updated the `Info` handler to return an array of `CertInfo` instead of a single certificate.
- Improved error handling for cases with no available certificates.
- Refactored related error messages for clarity.
- Updated various files to utilize gperr.Group for cleaner concurrency error handling.
- Removed sync.WaitGroup usage, simplifying the code structure.
- Ensured consistent error reporting across different components.
Extra providers were not being properly initialized during NewProvider(),
causing certificate registration and renewal scheduling to be skipped.
- Add ConfigExtra type with idx field for provider indexing
- Add MergeExtraConfig() for inheriting main provider settings
- Add setupExtraProviders() for recursive extra provider initialization
- Refactor NewProvider to return error and call setupExtraProviders()
- Add provider-scoped logger with "main" or "extra[N]" name
- Add batch operations: ObtainCertIfNotExistsAll(), ObtainCertAll()
- Add ForceExpiryAll() with completion tracking via WaitRenewalDone()
- Add RenewMode (force/ifNeeded) for controlling renewal behavior
- Add PrintCertExpiriesAll() for logging all provider certificate expiries
Summary of staged changes:
- config.go: Added ConfigExtra type, MergeExtraConfig(), recursive validation with path uniqueness checking
- provider.go: Added provider indexing, scoped logger, batch cert operations, force renewal with completion tracking, RenewMode control
- setup.go: New file with setupExtraProviders() for proper extra provider initialization
- setup_test.go: New tests for extra provider setup
- multi_cert_test.go: New tests for multi-certificate functionality
- renew.go: Updated to use new provider API with error handling
- state.go: Updated to handle NewProvider error return
Multi-certificate, SNI matching with exact map and suffix tree
Add support for multiple TLS certificates with SNI-based selection. The
root provider maintains a single centralized SNI matcher that uses an
exact match map for O(1) lookups, falling back to a suffix tree for
wildcard matching.
Key features:
- Add `Extra []Config` field to autocert.Config for additional certificates
- Each extra entry must specify unique `cert_path` and `key_path`
- Extra certs inherit main config (except `email` and `extra` fields)
- Extra certs participate in ACME obtain/renew cycles independently
- SNI selection precedence: exact match > wildcard match, main > extra
- Single centralized SNI matcher on root provider rebuilt after cert changes
The SNI matcher structure:
- Exact match map: O(1) lookup for exact domain matches
- Suffix tree: Efficient wildcard matching (e.g., *.example.com)
Implementation details:
- Provider.GetCert() now uses SNI from ClientHelloInfo for selection
- Main cert is returned as fallback when no SNI match is found
- Extra providers are created as child providers with merged configs
- SNI matcher is rebuilt after Setup() and after ObtainCert() completes
- Introduced a sync.Pool for ResponseRecorder to optimize memory usage.
- Updated ServeHTTP method to utilize the new GetResponseRecorder and PutResponseRecorder functions.
- Adjusted NewResponseRecorder to leverage the pooling mechanism.
- Updated health-related functions to return simplified health information.
- Introduced HealthStatusString type for correct swagger and schema generation.
- Refactored HealthJSON structure to utilize the new HealthStatusString type.
- Modified functions to accept context.Context as a parameter for better context management.
- Updated Init methods in Proxmox and Config to use the provided context.
- Adjusted UpdatePorts and NewProxmoxProvider to utilize the context for operations.
- Added ShortLinkMatcher to handle short link routing.
- Integrated short link handling in Entrypoint.
- Introduced tests for short link matching and dispatching.
- Configured default domain suffix for subdomain aliases.
