- 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.
- Added support for health checks using the h2c scheme.
- Refactored common header setting into a dedicated function.
- Updated CheckHealth method to differentiate between HTTP and h2c checks.
- Added logic to strip the trailing :port from the host when searching for routes.
- Updated findRouteByDomains function to ensure consistent host formatting.
- Added related tests
- Introduced CommandRoute to handle routing requests to other defined routes.
- Added validation to ensure a single argument is provided for the route.
- Implemented command handler to serve the specified route or return a 404 error if not found.
- Updated route iteration to include all routes, including excluded ones.
- Renamed existing functions for clarity.
- Adjusted health info retrieval to reflect changes in route iteration.
- Improved route management by adding health monitoring capabilities for excluded routes.
- Added `listenDebugServer` function to handle debug requests.
- Introduced table based debug page with different functionalities.
- Updated Makefile to use `scc` for code analysis instead of `cloc`.
