Major refactoring of the access logging infrastructure to improve code organization and add proper console/stdout logging support.
- Renamed `Writer` interface to `File` and consolidated with `SupportRotate`
- Renamed `Log(req, res)` to `LogRequest(req, res)` for clarity
- Added new `ConsoleLogger` with zerolog console writer for formatted stdout output
- Moved type definitions to new `types.go` file
- Changed buffer handling from `[]byte` returns to `*bytes.Buffer` parameters
- Renamed internal files for clarity (`access_logger.go` → `file_access_logger.go`)
- Fixed fileserver access logging timing: moved logging after handler execution with defer
- Correct response handling in Fileserver
- Remove deprecated field `buffer_size`
- Simplify and removed unnecessary code
All callers have been updated to use the new APIs.
- Changed error returned for invalid arguments in CommandPass and CommandPassAlt to ErrExpectNoArg.
- Added validation to ensure response handlers are the last commands in the execution order.
- Updated error messages for command sequence validation to clarify requirements for terminating and bypass commands.
- 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
* **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.
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.
- 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.
- 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.
- 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.
- Introduced a new checker for HTTP protocols (http, https, h3) in the routing rules.
- Added corresponding test cases to validate protocol matching behavior in requests.
- Removed unnecessary requestInternal struct and directly accessed the context field of http.Request.
- Simplified the initialization of ctxFieldOffset.
- Introduced origContentLength and bodyModified fields to track original content length and body modification status.
- Updated ContentLength and ContentLengthStr methods to return accurate content length based on body modification state.
- Adjusted Write and FlushRelease methods to ensure proper handling of Content-Length header.
- Modified middleware to use the new ContentLengthStr method.
- Moved health check constants from common package alongside type definition.
- Updated health check configuration to use struct directly instead of pointers.
- Introduced global default health check config
Refactor ServeHTTP to properly handle response body mutations by:
- Using ResponseModifier to capture response before modification
- Reading body content and allowing middleware to modify it
- Writing modified body back if changed during modification
- Ensuring proper order: RequestModifier before, ResponseModifier after next()
Previously, httputils.NewModifyResponseWriter did not correctly handle
body mutations. The new implementation captures the full response,
allows modification via modifyResponse, and properly writes back any
changes to the body.
Add BodyReader() and SetBody() methods to ResponseModifier to support
reading and replacing response body content.
