更新：

VNC 进入构建机器（不做任何更改）以某种方式修复了这个......奇怪

语境

我们使用 Mac EC2 实例 CI 集群来运行 UI 测试。集群设置为每晚回收。这意味着新集群是在早上配置的。我们注意到测试在一天中变得越来越不稳定。

• 构建 312 是早上的第一个构建。
• 红色是失败的测试，橙色是静音测试，黄色是片状测试，灰色是未知状态
• 提交只是触发构建的空白自动提交。测试内容相同。
• 注意：Bluepill 配置为每台机器运行一个模拟器（无并发）

日志

片状测试或失败通常是由于“等待某些资源空闲”并达到超时，或某些网络请求完成。失败或不稳定的测试也有一个共同点，即它们通常与视频有关

这是几个示例日志

等待应用空闲

Timed out waiting for app to idle. 
The following idling resources are busy.

我正在使用BluePill来管理诸如Rails的延迟作业之类的进程.在BluePill日志中,我收到此消息:

W, [2010-09-27T01:23:20.447053 #19441]  WARN -- : [fsg_distro:delayed_job] pid_file /srv/fsg_distro/shared/pids/delayed_job.pid does not exist or cannot be read
W, [2010-09-27T01:23:20.447368 #19441]  WARN -- : [fsg_distro:delayed_job] Executing start command: ruby script/delayed_job -e production start
I, [2010-09-27T01:23:20.469165 #19441]  INFO -- : [fsg_distro:delayed_job] Going from down => starting

所以它声称丢失了一个pid文件,但是当BluePill启动延迟作业进程时,不应该创建pid吗？

更新 要更清楚地了解此错误,我可以手动成功运行该命令,但Bluepill无法运行启动命令.当我手动运行它时,它看起来像这样:

rails@george:/srv/fsg_distro/current$ /usr/bin/env RAILS_ENV=production /usr/bin/ruby /srv/fsg_distro/current/script/delayed_job start
delayed_job: process with pid 17564 started. 

当我使用Bluepill运行它时,它看起来像这样:

W, [2010-10-03T21:24:13.943136 #17326]  WARN -- : [fsg_distro:delayed_job] pid_file /srv/fsg_distro/shared/pids/delayed_job.pid does not exist or cannot be read

由于unicorn_rails抱怨不同的gem版本,我们在bluepill文件中移动了bundle exec unicorn_rails ... 这个变化解决了特定问题和事情的开始和停止,但是当我们尝试sudo bluepill状态时,我们现在得到了

独角兽(pix:XXXXXX):不受监控

看起来像bluepill现在没有监控独角兽进程.如果我停止子进程,它将重新启动子进程,但不会重新启动父进程.

我已经四处寻找,但对这个问题找不到多少,并希望有人可以对此有所了解.bluepill配置文件是

app_dir = "/opt/local/share/httpd/apps/xyz"
Bluepill.application('xyz', :log_file => "#{app_dir}/current/log/bluepill.log") do |app|
  app.process('unicorn') do |process|
    process.pid_file    = "#{app_dir}/shared/pids/unicorn.pid"
    process.working_dir = "#{app_dir}/current"

    process.stdout = process.stderr = "#{app_dir}/shared/log/unicorn.err.log"
    process.start_command = "bundle exec unicorn_rails -D -c #{app_dir}/current/config/environments/production/unicorn.rb -E production"
    process.stop_command = "kill -QUIT {{PID}}"
    process.restart_command = "kill -USR2 {{PID}}"

    process.start_grace_time = 8.seconds
    process.stop_grace_time = 5.seconds
    process.restart_grace_time = 13.seconds

    process.monitor_children do |child_process|
      child_process.stop_command = "kill -QUIT {{PID}}"

      child_process.checks :mem_usage, :every => 10.seconds, :below => 200.megabytes, :times => [3,5] …

我有bluepill设置来监控我的delayed_job进程.

使用Ubuntu 12.04.

我正在使用Ubuntu启动并监控bluepill服务本身upstart.我的upstart配置在(/etc/init/bluepill.conf)之下.

description "Start up the bluepill service"

start on runlevel [2]
stop on runlevel [016]

expect fork
exec sudo /home/deploy/.rvm/wrappers/<app_name>/bluepill load /home/deploy/websites/<app_name>/current/config/server/staging/delayed_job.bluepill

# Restart the process if it dies with a signal
# or exit code not given by the 'normal exit' stanza.
respawn

我也试过expect daemon而不是expect fork.我也试过expect...完全删除线.

当机器启动时,bluepill启动正常.

$ ps aux | grep blue

bluepill过程的PID在这里是1154.但 …

我正在尝试使用 AC6 SystemWorkBench 和 ST-LINK v2 设备使用 CS32F103C8T6 芯片闪存蓝丸克隆。这是一个从 STM32CubeMX 构建的项目 - 我使用的是 MacOS Mojave 机器。这是尝试刷新设备时的输出。

我正在尝试使用 stlink-v2 连接到“stm32”“bluepill”来编写一些代码

每当我运行 openocd 时，它都无法连接 我的 openocd.cfg 文件如下所示

我有一个 Blue Pill，我想使用TinyGo对其进行编程，但 Blue Pill 没有（明显的）硬件编程方法。所以，我买了一个STLINK-V3MINI，希望能用JTAG/SWD来编程。我不确定如何将两者联系起来，并在我天真地将两者联系起来并破坏某些东西之前寻求指导。

这是 STLINK-V3MINI：

这是 STDC14 连接器：

STLINK用户指南的第 19 页有 STDC14 的引脚分配，但我无法将其与 TinyGo 的文档相关联，该文档表明需要SWIO, SWCLK,3v 和GND.
