Add tests/e2e/http2_test.go covering the http2 handler/listener/connector/dialer
end-to-end through the canonical gost-as-client pattern (8 subtests: forward,
auth, bypass, probeResist/metadata, h2 stream multiplexing). Include
testdata/http2/{server,server_auth,server_bypass,server_proberesist,client,
client_auth}.yaml. Note that h2/h2c listeners pair with the tunnel handler
and only http2 listener pairs with handler http2 (reads r/w from metadata).

Tighten TestDNSHostMapper by pointing the handler at an unreachable upstream
so unmapped names fail at the exchanger, confirming the host-mapper path was
the sole reason mapped names resolved. Fix http_idle_timeout.py to speak HTTP
through the CONNECT tunnel rather than a raw ping, matching the echo backend.

+# CLAUDE.md — gost/
+
+CLI binary entry point for GOST (GO Simple Tunnel). This module compiles the `gost` command.
+
+## Build & Run
+
+```bash
+cd gost && go build ./cmd/gost/...
+
+# Cross-compile
+CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -ldflags="-s -w" ./cmd/gost/...
+
+# Build all platforms
+make all
+
+# Run
+./gost -L "http://:8080" -F "socks5://:1080"
+./gost -C gost.yml
+```
+
+## Structure
+
+| File | Purpose |
+|------|---------|
+| `cmd/gost/main.go` | CLI entry point: flag parsing, multi-worker mode (`--` separator), program launch via `svc.Run` |
+| `cmd/gost/program.go` | Service lifecycle (`Init`/`Start`/`Stop`), config loading, API/metrics/profiling servers, SIGHUP reload |
+| `cmd/gost/register.go` | Blank imports for all built-in handlers, listeners, dialers, connectors — triggers `init()` registration |
+| `cmd/gost/version.go` | Version string (`3.3.0`) |
+
+## CLI Flags
+
+| Flag | Usage |
+|------|-------|
+| `-L` | Inline service definition (repeatable) |
+| `-F` | Inline chain node definition (repeatable) |
+| `-C` | Path to config file (YAML/JSON) |
+| `-D` / `-DD` | Debug / trace logging |
+| `-api` | API service address (e.g. `:8080`) |
+| `-metrics` | Prometheus metrics address |
+| `-O` | Output merged config as yaml or json, then exit |
+| `-V` | Print version and exit |
+
+## Multi-Worker Mode
+
+Arguments separated by ` -- ` spawn multiple worker processes via `exec.CommandContext`. Each worker runs as a child process with `_GOST_ID` set. Any worker's exit cancels all others. This is triggered in `init()` before flag parsing.
+
+## Service Lifecycle
+
+- `Init` → calls `parser.Init()` with all CLI/config inputs
+- `Start` → `parser.Parse()` → `loader.Load()` → `p.run()` (starts services, API, metrics, profiling)
+- `Stop` → cancels reload context, closes all services
+- SIGHUP → `reloadConfig()` re-parses and re-runs without restarting the process
+
+## Key Dependencies
+
+- `github.com/go-gost/core` — interface definitions
+- `github.com/go-gost/x` — all implementations, config, registry
+- `github.com/judwhite/go-svc` — OS service framework (handles daemon/SIGHUP/SIGTERM)
+
+## Registration Pattern
+
+All components register via `init()` side-effects in their packages. `cmd/gost/register.go` triggers them with blank imports. When adding a new built-in handler/listener/dialer/connector, add a blank import here.
+
+## Tests
+
+Tests are in `tests/e2e/` — integration tests using the built binary. No unit tests. Run with `go test ./tests/e2e/...`.

+# 执行计划：HTTP Handler E2E 测试 + utils.go 重构
+
+## 背景
+
+从 PLAN.md 的 Step 0 和 Step 1A 开始实施。HTTP proxy 是 gost 最基础的协议，目前 e2e 测试仅覆盖 shadowsocks 和 parallel selector。本计划先重构 utils.go 提取公共 helper，然后用 helper 写 HTTP handler 测试套件，最后同步重构 shadowsocks_test.go。
+
+## 变更文件清单
+
+| 文件 | 操作 | 说明 |
+|------|------|------|
+| `tests/e2e/utils.go` | 修改 | 新增 `RunTCPCase` / `RunUDPCase` |
+| `tests/e2e/http_test.go` | 新建 | HTTP proxy 测试套件 |
+| `tests/e2e/testdata/http/server.yaml` | 新建 | 无 auth 的 HTTP proxy 服务器 |
+| `tests/e2e/testdata/http/server_auth.yaml` | 新建 | 带 auth 的 HTTP proxy 服务器 |
+| `tests/e2e/shadowsocks_test.go` | 修改 | 重构为使用 `RunTCPCase` / `RunUDPCase` |
+
+---
+
+## Step 1: 修改 `utils.go` — 提取 RunTCPCase / RunUDPCase
+
+从 `shadowsocks_test.go` 的 `runTCPCase` 和 `runUDPCase` 提取为包级函数。关键差异：参数需要传入 echo container IP 和 echo container 本身（用于 dump logs）。
+
+### RunTCPCase 签名与逻辑
+
+```go
+// RunTCPCase runs a full TCP proxy test case:
+// start server → render client config → start client → curl assertion → cleanup.
+func RunTCPCase(t *testing.T, ctx context.Context, networkName, echoIP string,
+    name, serverConfig, clientConfig string)
+```
+
+逻辑（从 shadowsocks_test.go:132-160 提取，一字不差）：
+1. 生成 serverAlias = `name + "-server"`
+2. `RunGostContainerWithOptions(ctx, networkName, serverConfig, [serverAlias], ["8388/tcp"])`
+3. `defer serverC.Terminate(ctx)`
+4. `RenderConfig(clientConfig, {ServerAddr: serverAlias + ":8388"})`
+5. `defer os.Remove(rendered)`
+6. `RunGostContainerWithPorts(ctx, networkName, rendered, "8080/tcp")`
+7. `defer clientC.Terminate(ctx)`
+8. `clientC.Exec(ctx, ["curl", "-v", "-s", "-x", "http://127.0.0.1:8080", "http://<echoIP>:5678"])`
+9. 断言 exitCode==0 且 body 包含 `"hello-gost"`，失败时 DumpLogs
+
+**问题：端口硬编码**。shadowsocks 用 8388 作为服务端口，但其他协议可能用不同端口。需要参数化。
+
+### 修正设计 — 参数化端口
+
+```go
+type TCPOptions struct {
+    ServerPort    string // 容器内服务端口，默认 "8388/tcp"
+    ClientPort    string // 客户端代理端口，默认 "8080/tcp"
+}
+
+func RunTCPCase(t *testing.T, ctx context.Context, networkName, echoIP string,
+    name, serverConfig, clientConfig string, opts ...TCPOptions)
+```
+
+当 `opts` 为空时使用默认值 `{ServerPort: "8388/tcp", ClientPort: "8080/tcp"}`。这样 shadowsocks 测试无需任何改动，而 HTTP 测试可传 `TCPOptions{ServerPort: "8080/tcp", ClientPort: "8080/tcp"}`。
+
+等一下 — 仔细看 shadowsocks 的 server 容器暴露的是 `8388/tcp`，HTTP proxy 场景下只有一个 gost 容器（不做 server→client 链路），直接暴露 proxy 端口。
+
+**重新思考：HTTP proxy 不需要 server+client 两容器模式。**
+
+HTTP proxy 测试是最简单的模式 — 只需一个 gost 容器运行 HTTP proxy，然后容器内 curl 通过它访问 echo server。这和 parallel_selector_test.go 的模式一致。但为了统一框架和后续协议（SOCKS5、relay 等都需要 server+client 模式），我们应该：
+
+- HTTP 的"无 auth"用例：**单容器模式**（同 parallel_selector）
+- HTTP 的"带 auth"用例：**也可以单容器**，只需在 curl 加 `--proxy-user`
+
+所以 HTTP proxy 不需要 server/client 分离，但 RunTCPCase helper 仍然服务于 SOCKS5/relay 等需要链路的协议。
+
+### 最终 RunTCPCase 设计
+
+```go
+func RunTCPCase(t *testing.T, ctx context.Context, networkName, echoIP, name string,
+    serverConfig, clientConfig string, serverPort, clientPort string)
+```
+
+- `serverPort`: 服务端容器暴露端口，如 `"8388/tcp"`
+- `clientPort`: 客户端容器暴露端口，如 `"8080/tcp"`
+- 渲染模板时用 `ServerAddr: serverAlias + ":" + strings.TrimSuffix(serverPort, "/tcp")`
+
+### RunUDPCase 设计
+
+```go
+func RunUDPCase(t *testing.T, ctx context.Context, networkName, name string,
+    serverConfig, clientConfig string, serverPort, clientPort string)
+```
+
+逻辑从 shadowsocks_test.go:76-126 提取。
+

+
+## Step 2: 新建 `testdata/http/` 配置文件
+
+### `testdata/http/server.yaml` — 无 auth 的 HTTP proxy
+
+```yaml
+services:
+- name: http-proxy
+  addr: :8080
+  handler:
+    type: http
+  listener:
+    type: tcp
+```
+
+单容器即可测试：gost 启动后在 :8080 提供 HTTP proxy 服务。
+
+### `testdata/http/server_auth.yaml` — 带 auth 的 HTTP proxy
+
+```yaml
+services:
+- name: http-proxy-auth
+  addr: :8080
+  handler:
+    type: http
+    auther: auther-0
+  listener:
+    type: tcp
+
+authers:
+- name: auther-0
+  auths:
+  - username: user
+    password: pass
+```
+
+---
+
+## Step 3: 新建 `http_test.go`
+
+### 套件结构
+
+```go
+type HTTPSuite struct {
+    suite.Suite
+    ctx    context.Context
+    echoC  testcontainers.Container
+    echoIP string
+}
+
+func (s *HTTPSuite) SetupSuite()    // 启动 TCP echo
+func (s *HTTPSuite) TearDownSuite() // 关闭 echo
+
+func (s *HTTPSuite) TestHTTPProxy()       // 无 auth
+func (s *HTTPSuite) TestHTTPProxyAuth()   // 带 auth
+
+func TestHTTPSuite(t *testing.T) {
+    suite.Run(t, new(HTTPSuite))
+}
+```
+
+### TestHTTPProxy — 单容器模式（同 parallel_selector）
+
+```go
+func (s *HTTPSuite) TestHTTPProxy() {
+    gostC, err := RunGostContainerWithPorts(s.ctx, SharedNetworkName,
+        "testdata/http/server.yaml", "8080/tcp")
+    s.Require().NoError(err)
+    defer gostC.Terminate(s.ctx)
+
+    cmd := []string{"curl", "-v", "-s", "-x", "http://127.0.0.1:8080",
+        fmt.Sprintf("http://%s:5678", s.echoIP)}
+    code, out, err := gostC.Exec(s.ctx, cmd)
+    s.Require().NoError(err)
+
+    body, err := io.ReadAll(out)

+    }
+    s.Require().Equal(0, code)
+    s.Require().Contains(string(body), "hello-gost")
+}
+```
+
+### TestHTTPProxyAuth — 带 auth 验证
+
+```go
+func (s *HTTPSuite) TestHTTPProxyAuth() {
+    gostC, err := RunGostContainerWithPorts(s.ctx, SharedNetworkName,
+        "testdata/http/server_auth.yaml", "8080/tcp")
+    s.Require().NoError(err)
+    defer gostC.Terminate(s.ctx)
+
+    // 测试1：无 auth 应失败（407）
+    s.T().Run("no-auth-should-fail", func(t *testing.T) {
+        cmd := []string{"curl", "-s", "-o", "/dev/null", "-w", "%{http_code}",
+            "-x", "http://127.0.0.1:8080", fmt.Sprintf("http://%s:5678", s.echoIP)}
+        code, out, _ := gostC.Exec(s.ctx, cmd)
+        body, _ := io.ReadAll(out)
+        // curl exit code 非 0 或 HTTP status 是 407
+        // 注意：gost HTTP proxy 在无 auth 时返回 407，curl 不会自动重试
+        // 所以这里验证返回码是 407 或 curl 返回非零
+        httpStatus := strings.TrimSpace(string(body))
+        s.Assert().True(code != 0 || httpStatus == "407",
+            "expected auth failure, got status: %s, exit code: %d", httpStatus, code)
+    })
+
+    // 测试2：正确 auth 应成功
+    s.T().Run("with-auth-should-succeed", func(t *testing.T) {
+        cmd := []string{"curl", "-v", "-s", "-x",
+            "http://user:pass@127.0.0.1:8080",
+            fmt.Sprintf("http://%s:5678", s.echoIP)}
+        code, out, err := gostC.Exec(s.ctx, cmd)
+        s.Require().NoError(err)
+
+        body, err := io.ReadAll(out)
+        s.Require().NoError(err)

+        s.Require().Equal(0, code)
+        s.Require().Contains(string(body), "hello-gost")
+    })
+}
+```
+
+### 注意事项
+- HTTP proxy 是**单容器模式**，不需要 server/client 分离（不像 shadowsocks 需要解密/加密链路）
+- auth 测试分两步：先验证无 auth 被拒（407），再验证正确 auth 成功
+- curl 使用 `http://user:pass@host:port` 格式传递 proxy auth

+
+## Step 4: 重构 `shadowsocks_test.go`
+
+将 `runTCPCase` 和 `runUDPCase` 方法替换为调用 `utils.go` 中的 `RunTCPCase` / `RunUDPCase`：
+
+**Before**:
+```go
+func (s *ShadowsocksSuite) TestShadowsocksTCP() {
+    s.runTCPCase("aes256gcm", "testdata/shadowsocks/tcp_server_aes256gcm.yaml", "testdata/shadowsocks/tcp_client_aes256gcm.yaml")
+    s.runTCPCase("chacha20", "testdata/shadowsocks/tcp_server_chacha20.yaml", "testdata/shadowsocks/tcp_client_chacha20.yaml")
+}
+```
+
+**After**:
+```go
+func (s *ShadowsocksSuite) TestShadowsocksTCP() {
+    RunTCPCase(s.T(), s.ctx, SharedNetworkName, s.echoIP, "aes256gcm",
+        "testdata/shadowsocks/tcp_server_aes256gcm.yaml",
+        "testdata/shadowsocks/tcp_client_aes256gcm.yaml",
+        "8388/tcp", "8080/tcp")
+    RunTCPCase(s.T(), s.ctx, SharedNetworkName, s.echoIP, "chacha20",
+        "testdata/shadowsocks/tcp_server_chacha20.yaml",
+        "testdata/shadowsocks/tcp_client_chacha20.yaml",
+        "8388/tcp", "8080/tcp")
+}
+```
+
+删除 `runTCPCase` 和 `runUDPCase` 方法。UDP 测试同理。
+
+---
+
+## 实施顺序
+
+1. **`utils.go`** — 添加 `RunTCPCase` + `RunUDPCase`（不删除任何现有函数）
+2. **`testdata/http/`** — 创建 `server.yaml` + `server_auth.yaml`
+3. **`http_test.go`** — 创建 HTTP 套件
+4. **编译验证** — `cd gost && go build ./... && go vet ./tests/e2e/...`
+5. **`shadowsocks_test.go`** — 重构为使用新 helper
+6. **最终编译验证** — `go build ./... && go vet ./tests/e2e/...`
+7. **运行测试** — `go test ./tests/e2e/ -v -run TestHTTPSuite -timeout 5m`
+8. **回归测试** — `go test ./tests/e2e/ -v -run TestShadowsocksSuite -timeout 5m`

+# Plan: Expand E2E Test Suite
+
+## Context
+
+The e2e test framework (`tests/e2e/`) currently covers only **2 protocols** (Shadowsocks, parallel selector) out of **~30+ registered protocols** in gost. This plan systematically adds test coverage for all major protocols, following the existing Docker-based testcontainers pattern exactly.
+
+**Key insight**: gost auto-generates self-signed TLS certs when none are provided (`x/config/parsing/tls.go` — `BuildDefaultTLSConfig`), and clients with default config skip cert verification. This means TLS-based protocols (ws→wss, h2c→h2, quic, etc.) can be tested **without mounting cert files**.
+
+---
+
+## Step 0: Refactor `utils.go` — Add Reusable Test Helpers
+
+**File**: `tests/e2e/utils.go`
+
+Extract the repeated patterns from `shadowsocks_test.go` into reusable helpers:
+
+1. **`RunTCPCase(t, ctx, networkName, echoIP, name, serverConfig, clientConfig string)`** — Full lifecycle: start server → render client config → start client → curl assertion → cleanup. Extracts the logic from `ShadowsocksSuite.runTCPCase`.
+
+2. **`RunUDPCase(t, ctx, networkName, name, serverConfig, clientConfig string)`** — Same for UDP: start server → render client → start client → dial UDP → retry loop → assertion → cleanup. Extracts from `runUDPCase`.
+
+These eliminate ~40 lines of boilerplate per suite. Each suite's test methods become one-liners:
+```go
+func (s *SOCKS5Suite) TestSOCKS5TCP() {
+    RunTCPCase(s.T(), s.ctx, SharedNetworkName, s.echoIP, "socks5-tcp",
+        "testdata/socks5/tcp_server.yaml", "testdata/socks5/tcp_client.yaml")
+}
+```
+
+---
+
+## Step 1: Tier 1 — Core Protocols (Plain TCP, No Special Infrastructure)
+
+Each suite follows the exact pattern: suite struct → `SetupSuite` (echo containers) → `TearDownSuite` → test methods calling `RunTCPCase`/`RunUDPCase` → `suite.Run()` entry point.
+
+### 1A. HTTP Proxy Suite
+- **Files**: `http_test.go`, `testdata/http/` (2 configs)
+- **Configs**: `server.yaml` (handler `http`, listener `tcp`), `server_auth.yaml` (+ basic auth)
+- **Tests**: `TestHTTPProxy`, `TestHTTPProxyAuth` (curl with `--proxy-user`)
+- **Note**: Simplest test — single gost container acts as HTTP proxy
+
+### 1B. SOCKS5 Suite
+- **Files**: `socks5_test.go`, `testdata/socks5/` (4 configs)
+- **Configs**: `tcp_server.yaml` (handler `socks5`), `tcp_client.yaml` (connector `socks5`, dialer `tcp`), + auth variants
+- **Tests**: `TestSOCKS5TCP`, `TestSOCKS5TCPAuth`
+
+### 1C. SOCKS4 Suite
+- **Files**: `socks4_test.go`, `testdata/socks4/` (4 configs)
+- **Configs**: `tcp_server.yaml` (handler `socks4`), `tcp_client.yaml` (connector `socks4`), + socks4a variants
+- **Tests**: `TestSOCKS4TCP`, `TestSOCKS4aTCP`
+
+### 1D. HTTP2 Cleartext Suite
+- **Files**: `http2_test.go`, `testdata/http2/` (2 configs)
+- **Configs**: `tcp_server.yaml` (handler `http2`, listener `http2`), `tcp_client.yaml` (connector `http2`, dialer `http2`)
+- **Tests**: `TestHTTP2TCP`
+
+### 1E. Relay Suite
+- **Files**: `relay_test.go`, `testdata/relay/` (4 configs)
+- **Configs**: `tcp_server.yaml` (handler `relay`, listener `tcp`), `tcp_client.yaml` (connector `relay`, dialer `tcp`), + auth variants
+- **Tests**: `TestRelayTCP`, `TestRelayTCPAuth`
+
+---
+
+## Step 2: Tier 2 — TLS/Transport Protocols
+
+Same pattern but using TLS listeners/dialers. No explicit cert files needed — gost auto-generates them.
+
+### 2A. TLS Suite
+- **Files**: `tls_test.go`, `testdata/tls/` (4 configs)
+- **Tests**: `TestTLSHTTPProxy` (handler `http` + listener `tls`), `TestTLSSOCKS5` (handler `socks5` + listener `tls`)
+
+### 2B. WebSocket Suite
+- **Files**: `ws_test.go`, `testdata/ws/` (4 configs)
+- **Tests**: `TestWSSOCKS5` (dialer `ws`), `TestWSSSOCKS5` (dialer `wss`)
+
+### 2C. gRPC Suite
+- **Files**: `grpc_test.go`, `testdata/grpc/` (2 configs)
+- **Tests**: `TestGRPCSOCKS5` (listener `grpc`, metadata `insecure: true`)
+
+### 2D. HTTP/2 TLS (h2) Suite
+- **Files**: `h2_test.go`, `testdata/h2/` (2 configs)
+- **Tests**: `TestH2HTTP2Proxy` (listener `h2`, dialer `h2`)
+
+### 2E. QUIC Suite
+- **Files**: `quic_test.go`, `testdata/quic/` (2 configs)
+- **Tests**: `TestQUICHTTP` (listener `quic`, handler `http` — uses UDP ports)
+
+### 2F. KCP Suite
+- **Files**: `kcp_test.go`, `testdata/kcp/` (2 configs)
+- **Tests**: `TestKCPSOCKS5` (listener `kcp`, handler `socks5` — uses UDP)
+
+### 2G. Multiplex Variants (mws/mwss/mtls/mtcp)
+- **Files**: `mux_test.go`, `testdata/mux/` (6 configs)
+- **Tests**: `TestMWSSOCKS5`, `TestMWSSSOCKS5`, `TestMtlSSOCKS5`, `TestMtcpSOCKS5`
+
+### 2H. Obfuscation (ohttp/otls)
+- **Files**: `obfs_test.go`, `testdata/obfs/` (4 configs)
+- **Tests**: `TestOHTTP`, `TestOTLS`
+
+### 2I. PHT (HTTP Pipe)
+- **Files**: `pht_test.go`, `testdata/pht/` (4 configs)
+- **Tests**: `TestPHT`, `TestPHTS`
+
+---
+
+## Step 3: Tier 3 — Special Infrastructure (Deferred)
+
+These require Docker capabilities (`NET_ADMIN`, `NET_RAW`), SSH key generation, or iptables setup. Implemented after Tiers 1-2 are stable.
+
+| Protocol | Challenge | Approach |
+|----------|-----------|----------|
+| SSH/sshd | Host key generation | Generate SSH key at test time, mount into container |
+| HTTP/3/WebTransport | QUIC+UDP, TLS | Uses UDP like QUIC suite; auto certs work |
+| TUN/TAP | `CAP_NET_ADMIN`, `/dev/net/tun` | Privileged container + routing setup |
+| Tungo/MASQUE | Same as TUN | Same approach |
+| ICMP | `CAP_NET_RAW`, raw sockets | Privileged container |
+| Redirect (red/redu) | iptables rules | Privileged + iptables setup in container |
+| DTLS | UDP + TLS | Auto certs; UDP port mapping |

+Integration tests that spin up real gost instances inside Docker containers and verify protocol behavior over the network.
+
+## Prerequisites
+
+- [Docker](https://docs.docker.com/get-docker/) (running daemon)
+- Go toolchain (for compiling the gost binary under test)
+
+## Running
+
+From the repository root:
+
+```bash
+# Run all e2e tests
+go test ./tests/e2e/ -v -timeout 10m
+
+# Run a specific test suite
+go test ./tests/e2e/ -v -run TestShadowsocksSuite -timeout 5m
+go test ./tests/e2e/ -v -run TestParallelSelectorSuite -timeout 5m
+
+# Use a pre-built gost binary (skips compilation)
+go test ./tests/e2e/ -v -gost-bin /path/to/gost
+```
+
+## Architecture
+
+```
+tests/e2e/
+├── Dockerfile                  # Shared base image (Alpine + curl, python3, etc.)
+├── main_test.go                # TestMain: compiles gost, creates Docker network
+├── utils.go                    # Helpers: container lifecycle, config rendering
+├── scripts/
+│   ├── tcp_echo.py             # HTTP echo server (responds with "hello-gost")

+├── testdata/                   # config files or data files for running cases
+├── shadowsocks_test.go         # Shadowsocks protocol tests
+└── parallel_selector_test.go   # Parallel node selector tests
+```
+
+### How it works
+
+1. **TestMain** (`main_test.go`) compiles the gost binary from `../../cmd/gost` (unless `-gost-bin` is provided) and creates a shared Docker network for all containers.
+2. Each test suite starts echo server containers (TCP/UDP), then launches separate gost containers for server and client roles.
+3. Client configs use Go template syntax (`{{.ServerAddr}}`) so the server address is injected at runtime.
+4. Tests verify end-to-end connectivity by sending traffic through the gost proxy chain and checking that the echo server responds correctly.
+
+## Tips
+
+- Increase `-timeout` for CI or slow networks. Container image builds on first run take extra time.
+- Use `-gost-bin` to avoid recompiling when iterating on tests locally.
+- Add `-v` to see container log output on failure.
+- RunGostContainer will wait for exposedPorts automatically, but it's not reliable for udp ports. So, you should check the readiness of udp ports inside cases.
