 # Starry Nginx App
 
-This app organizes nginx tests into four directories:
+Starry 下 nginx 应用的构建与测试入口。
 
-- `smoke/`: CI entry smoke test (the only connected nginx test in tgoskits)
-- `phase/`: stage-unit tests named by `x-x`, such as `nginx-1-3-lifecycle-tests.sh`
-- `stress/`: pressure test planning and future scripts
-- `debug/`: flexible issue-focused scripts
+## 测试模式
 
-## CI-Connected Entry
+guest 内统一入口 `/usr/bin/nginx-runner.sh <mode>`：
 
-Only smoke is connected:
+| mode | 用途 | CI |
+|------|------|----|
+| `smoke` | 仅 smoke | ✅ 唯一接入上层 CI |
+| `phase <id>` | 单阶段复测 | ❌ 手工 |
+| `all` | smoke + 全部 phase（阶段强隔离） | ❌ 手工 |
+| `stress` | 压测（当前 skip） | ❌ 手工 |
+| `debug <name>` | 单问题调试 | ❌ 手工 |
 
-```bash
-cargo xtask starry app run -t nginx --arch riscv64

-
-`qemu-*.toml` starts `/usr/bin/nginx-smoke-tests.sh` only.

-## Local Development CLI
+QEMU 入口按用途分目录：根 `qemu-<arch>.toml`（CI）、`qemu/all/`（手工全量）、
+`qemu/phase/`（手工单阶段）、`qemu/debug/`（手工调试）。
 
-Unified local CLI script:
+## 用法
 
 ```bash
-./apps/starry/nginx/nginx-cli-tests.sh smoke
-./apps/starry/nginx/nginx-cli-tests.sh phase1
-./apps/starry/nginx/nginx-cli-tests.sh phase2

+# ISSUE-004: BAD Method Probe Instability
+
+## Status
+
+- State: deferred (temporarily bypassed in phase2)
+- Scope: `BAD / HTTP/1.1` verification path in stage 2
+- Impact: does not block phase2 main flow
+
+## Symptom
+
+- In some runs, `busybox nc` returns an empty response (`<empty>`) for both:
+  - `BAD / HTTP/1.1`
+  - `GET / HTTP/1.1`
+- This can make a strict raw-probe assertion fail even when nginx behavior is normal.
+
+## Confirmed Observations
+
+- `curl -X BAD http://127.0.0.1:8080/...` stably returns `405`.
+- `nc.openbsd` raw BAD request stably returns `HTTP/1.1 405 Not Allowed`.
+- `busybox nc` may return `<empty>` under the same request pattern.
+
+## Current Decision
+
+- Keep phase2 BAD-method node as bypass (known issue log only).
+- Do not use `busybox nc` as pass/fail oracle for this node.
+- Continue tracking through debug scripts:
+  - `nginx-2-0-bad-method-debug.sh`
+  - `nginx-2-0-bad-method-matrix.sh`
+
+## Repro Commands
+
+```bash
+cargo xtask starry app qemu -t nginx --arch x86_64 --qemu-config apps/starry/nginx/qemu/debug/qemu-x86_64-bad-method-debug.toml
+cargo xtask starry app qemu -t nginx --arch x86_64 --qemu-config apps/starry/nginx/qemu/debug/qemu-x86_64-bad-method-matrix.toml
+```
+
+Optional phase20 (HTTP basic) retest:
+
+```bash
+cargo xtask starry app qemu -t nginx --arch x86_64 --qemu-config apps/starry/nginx/qemu/phase/qemu-x86_64-phase20.toml
+```
+
+## Next Follow-up
+
+- Add a minimal socket-level probe outside nginx to isolate whether this is:
+  - `busybox nc` behavior under StarryOS, or
+  - StarryOS socket timing/EOF behavior exposed by `busybox nc`.
+- After root cause is confirmed and fixed, restore strict assertion for the phase2 BAD-method node.

+# ISSUE-005: x86 Short Connection Timeout
+
+## Status
+
+- State: investigating
+- Scope: x86_64 Starry nginx phase31 short-connection loop
+- Impact: can fail `nginx-runner.sh all` at `phase31` with `NGINX_PHASE31_TEST_FAILED`
+
+## Symptom
+
+- `phase31` runs many short HTTP connections against nginx on `127.0.0.1:8080`.
+- On x86_64, the loop can exceed the per-probe or per-phase timeout budget.
+- The terminal failure usually appears as:
+
+```text
+NGINX_RUNNER_PHASE_BEGIN phase=phase31
+NGINX_PHASE31_TEST_FAILED
+NGINX_PHASE31_LOG: 100 short connections
+NGINX_RUNNER_PHASE_FAIL phase=phase31 rc=1
+NGINX_RUNNER_FAILED phase=phase31
+```
+
+Older logs also showed:
+
+```text
+NGINX_PHASE31_LOG: watchdog timeout
+Terminated
+```
+
+## Confirmed Observations
+
+- riscv64 passed the same nginx phase path.
+- x86_64 standalone `phase31` can fail, so the issue is not only cross-phase state from `all`.
+- A focused short-connection debug run once failed around iteration 143 with `curl rc=7` and `connection refused` while nginx received `SIGTERM`.
+- Raising the debug runner budget to 1800s made the timeout-wrapped short-connection debug pass 120 iterations.
+- Running the same debug loop without per-request `timeout` also passed 120 iterations.
+- The x86 loop is still very slow: `curl` reports tens of milliseconds of HTTP time, but the wall-clock loop averages several seconds per request.
+- A timing microbench shows the slow path starts before nginx/socket handling:
+
+| Bench | x86_64 | riscv64 |
+| --- | ---: | ---: |
+| shell arithmetic, 100 iters | 1s | 0s |
+| shell builtin `:`, 100 iters | 1s | 0s |
+| `/bin/true`, 100 iters | 32s | 10s |
+| `/bin/busybox true`, 100 iters | 38s | 10s |
+| `/bin/echo ok`, 100 iters | 36s | 15s |
+| `/bin/sleep 0`, 100 iters | 30s | 19s |
+| `/bin/date +%s`, 20 iters | 9s | 2s |
+| `/bin/sleep 1`, 5 iters | 6s | 5s |
+| `timeout 5 /bin/true`, 100 iters | 63s | 23s |
+| direct nginx `curl`, 40 iters | 91s | 31s |
+| `timeout 10 curl`, 40 iters | 106s | 34s |
+
+- `sleep 1` is roughly correct, so the primary issue is not a simple timer-frequency error.
+- Shell builtins are fast, while every external command has high fixed cost, so the primary issue is likely in x86 process launch/exec/exit/wait or user/kernel transition overhead.
+- `timeout` adds another external process and timer/signal layer, which makes the phase31 `timeout curl` loop more vulnerable.
+
+## Current Hypothesis
+
+- The HTTP request itself is not the main cost.
+- The x86_64 path spends excessive wall time in short-lived external command handling.
+- The current strongest suspects are x86 `execve` page-table work, x86 user/kernel transition overhead, and vfork/exec/wait scheduling latency.
+- The original `timeout 5 curl ...` assertion is therefore close to the x86 timing cliff and can fail nondeterministically.
+
+## Debugging Work So Far
+
+- Reproduced the original failure shape from `phase31`: `NGINX_PHASE31_TEST_FAILED` followed by `NGINX_RUNNER_FAILED phase=phase31`.
+- Verified that standalone x86_64 `phase31` can fail, so the issue is not only caused by earlier phases in `all`.
+- Added `nginx-3-1-short-connection-debug.sh` to run the same short-connection pattern with per-iteration curl status, stderr, nginx process state, socket state, and log tails.
+- The first timeout-wrapped debug run failed around iteration 143 with `curl rc=7` and `connection refused`; nginx had received `SIGTERM`, which matched the runner/default watchdog budget expiring rather than a stable nginx accept failure.
+- Raised the debug runner budget to 1800s and confirmed timeout-wrapped short connections can complete 120 iterations on x86_64.
+- Disabled per-request `timeout` in a direct debug run and confirmed 120 iterations also pass, but still take several hundred seconds.
+- Added `nginx-3-1-x86-timing-debug.sh` to split shell-only work from external-command, timeout, and curl loops.
+- Added a riscv64 timing-debug QEMU config and ran the same timing script as an architecture baseline.
+
+## Phase Workaround
+
+- `apps/starry/nginx/phase/nginx-3-1-short-connection-tests.sh` keeps the same HTTP assertion: 100 independent `curl -fsS` short connections must succeed.
+- The per-curl wall-clock timeout was raised from 5s to 15s through `SHORT_CONN_CURL_TIMEOUT`.
+- This does not weaken the response correctness check; it only avoids treating the current x86 external-command overhead as an nginx failure.
+- The runner phase budget remains the outer bound. The measured x86 timing debug still fits well below the standalone phase budget after this per-operation relaxation.
+
+## Code Pointers
+
+- `os/StarryOS/kernel/src/syscall/task/clone.rs`: `CloneArgs::do_clone`, vfork setup and parent wait.
+- `os/StarryOS/kernel/src/syscall/task/execve.rs`: `do_execve`, per-exec address-space creation, ELF load, and page-table switch.
+- `os/StarryOS/kernel/src/task/mod.rs`: `ProcessData::wait_vfork_done` / `notify_vfork_done`.
+- `components/axcpu/src/x86_64/uspace.rs`: x86 user context entry/exit and per-run FS/GS MSR handling.
+- `components/axcpu/src/x86_64/trap.S`: `enter_user` syscall/iret return path.
+- `components/axcpu/src/x86_64/context.rs`: task context switch and user page-table switch.
+
+## Suspicious Implementation Details
+
+- `execve` creates and installs a fresh address space for every external command. On x86_64 this includes kernel mapping copy, CR3 switch, and TLB effects that shell builtins avoid.
+- x86 user entry/exit does FS/GS MSR handling around `UserContext::run()`. Short-lived commands execute many syscall/user-return cycles during dynamic loader startup and process exit.
+- Fresh x86 `UserContext::new()` after `execve` may initially return through the `iretq` path instead of the faster syscall-return path.
+- BusyBox shell likely uses `vfork`/`CLONE_VFORK` for external commands. The parent blocks in `ProcessData::wait_vfork_done()` until the child execs or exits, so scheduling or wakeup latency is paid once per command.
+- `timeout curl` adds another external process plus timer/signal/wait behavior, which explains why it is significantly slower than direct `curl` and why phase31 is sensitive to a 5s per-operation deadline.
+
+## Debug Scripts
+
+- `nginx-3-1-short-connection-debug.sh`: nginx short-connection reproduction with detailed curl/nginx/socket logs.
+- `nginx-3-1-x86-timing-debug.sh`: microbench to compare shell loop, `/bin/true`, `timeout true`, direct curl, and timeout-wrapped curl.
+
+## Repro Commands
+
+```bash
+cargo xtask starry app qemu -t nginx --arch x86_64 --qemu-config apps/starry/nginx/qemu/debug/qemu-x86_64-short-connection-debug.toml

+cargo xtask starry app qemu -t nginx --arch riscv64 --qemu-config apps/starry/nginx/qemu/debug/qemu-riscv64-timing-debug.toml
+```
+
+## Next Follow-up
+
+- The bottleneck appears before networking: inspect x86 short-lived process execution first.
+- Compare `execve` page-table switching costs on x86, especially CR3/TLB work in `components/axcpu/src/x86_64/context.rs` and address-space replacement in `do_execve`.
+- Inspect x86 user/kernel round-trip overhead in `components/axcpu/src/x86_64/uspace.rs` and `components/axcpu/src/x86_64/trap.S`.
+- Inspect vfork/exec/wait wakeup latency in `CloneArgs::do_clone`, `ProcessData::wait_vfork_done`, `notify_vfork_done`, and `sys_waitpid`.
