现场：用户以管理员跑 -SetEnv -StartNow 时脚本抛 SetValueInvocationException（触发器上没有 StartWhenAvailable 属性）， 而它是在"已注销旧任务、尚未注册新任务"之间抛的，等于把 runner 任务删没了。 - StartWhenAvailable 改设到 settings（MSFT_TaskSettings 继承属性， CIM 属性列表里看不见但可直接赋值，实测 StartWhenAvailable=True） - 任务对象改由 New-WatchdogTaskPlan 统一构建，先构建、后注销旧任务 - Register-ScheduledTask 失败时显式告警"旧任务已删、CI 裸奔"并 exit 1 - 新增 -DryRun：免管理员即可全量校验 action/trigger/settings - -Status 增补上次运行时间与返回码，并提示"非管理员看不见任务" 同时更正根因：旧计划任务其实一直存在（非管理员会话看不见，先前误判为 "从未注册"），但它跑的是单次 run_runner.cmd——daemon 属"正常退出"而非 "失败"，计划任务的失败重启根本接不到，必须靠看门狗循环重拉。

.SYNOPSIS
|
|
Make the Gitea Actions runner on this machine survive restarts, and give it
|
|
a toolchain the SYSTEM service account can actually see.
|
|
|
|
.DESCRIPTION
|
|
Why this file exists (2026-10-11 CI audit, the "many jobs never ran" bug):
|
|
|
|
Six consecutive runs (16..21, i.e. 12 jobs) produced ZERO log lines. The
|
|
runner `win-stm32-ci` was simply offline, and two independent causes made
|
|
that permanent:
|
|
|
|
1. NO SUPERVISION. gitea-runner v4.0.1 `daemon` has no service support
|
|
(v4 removed `daemon install`), and it EXITS when the first Declare
|
|
call fails. The runner log shows exactly that after a Gitea restart:
|
|
|
|
level=error msg="fail to invoke Declare" error="unavailable:
|
|
dial tcp 127.0.0.1:3001: connectex: ... actively refused it."
|
|
Error: unavailable: dial tcp 127.0.0.1:3001 ...
|
|
|
|
...and the process is gone. So one Gitea restart (or one reboot)
|
|
silently kills CI until a human notices days later. Queued runs then
|
|
get cancelled by the NEXT push, because ci.yml sets
|
|
`concurrency.cancel-in-progress: true` -- which is why the symptom
|
|
looks like "tasks vanish" rather than "tasks fail".
|
|
|
|
2. NO MACHINE-LEVEL TOOLCHAIN. The runner service runs as SYSTEM.
|
|
pre-commit / cppcheck were only reachable through the interactive
|
|
user's PATH, and no machine-level DTU_* variable was ever set, so
|
|
even a live runner died in the L0 environment check.
|
|
|
|
This script installs the missing supervision (a watchdog launcher + a
|
|
scheduled task) and, with -SetEnv, writes the machine-level DTU_* variables
|
|
by discovering the tools the same way CI does.
|
|
|
|
Run elevated, from the repo:
|
|
|
|
powershell -ExecutionPolicy Bypass -File scripts\ci_runner_bootstrap.ps1 -SetEnv -StartNow
|
|
|
|
.PARAMETER RunnerDir
|
|
Directory holding gitea-runner.exe / config.yaml / .runner.
|
|
|
|
.PARAMETER GiteaUrl
|
|
Instance address the runner registered against (must match .runner's
|
|
"address"; the runner talks to it directly, not through the public URL).
|
|
|
|
.PARAMETER TaskName
|
|
Scheduled-task name for the watchdog.
|
|
|
|
.PARAMETER SetEnv
|
|
Discover and write MACHINE-level DTU_PRECOMMIT_PYTHON / DTU_CPPCHECK /
|
|
DTU_MSVC_CL. Existing values are preserved unless -Force.
|
|
|
|
.PARAMETER StartNow
|
|
Start the task after registering it.
|
|
|
|
.PARAMETER Status
|
|
Only report: task state, daemon process, Gitea reachability.
|
|
|
|
.PARAMETER DryRun
|
|
Build and validate the action / trigger / settings objects and print what
|
|
WOULD be done, writing and registering nothing. This is also the only way
|
|
to verify this script without elevation.
|
|
|
|
.PARAMETER Force
|
|
With -SetEnv, overwrite existing machine-level values.
|
|
|
|
.OUTPUTS
|
|
Progress lines. Exit codes: 0 = ok, 1 = precondition failed, 2 = not elevated.
|
|
|
|
.NOTES
|
|
Keep this file pure ASCII (PowerShell 5.1 decodes BOM-less files as CP936).
