(OSX)launchctl不允许Python停止

标签: python macos osx-lion launchd

我在Lion(10.7.3)上使用launchctl在系统启动时在2个不同的端口上加载2个SickBeard实例(一个python脚本)。

我在〜/ Library / LaunchAgents中的plist如下所示。

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
  <key>Label</key>
  <string>com.sickbeard.sickbeard</string>
  <key>ProgramArguments</key>
  <array>
       <string>/Library/Frameworks/Python.framework/Versions/2.7/bin/python</string>
       <string>/Users/james/Applications/Sick-Beard/SickBeard.py</string>
       <string>-q</string>
       <string>-d</string>
  </array>

  <key>StandardOutPath</key>
  <string>/var/log/sickbeard/sickbeard.log</string>
  <key>StandardErrorPath</key>
  <string>/var/log/sickbeard/sickbeard_error.log</string>

  <key>RunAtLoad</key>
  <true/>
</dict>
</plist>

我已经确认python从该位置启动,并且SB也是正确的......实际上两个Python实例在启动时都正确加载 - 请参阅&#34; top&#34;下方。

我遇到的问题是,虽然&#34; launchctl start com.sickbeard.sickbeard&#34;努力开始这个过程,&#34; launchctl stop com.sickbeard.sickbeard&#34;不会阻止它。 如果我尝试从GUI启动自动更新,则会失败,提示我查看日志。 日志在适当的时间戳中包含以下内容。

Git确实在/ usr / local / bin / git中。 奇怪的是,我不记得改变任何可能导致这个问题的事情 - 以前有人遇到过这个问题吗? 我已经浏览了这些论坛上的所有启动线程,并尝试过对plists等所有小小的个性化更改,但没有一个真正有任何区别。

在我未经训练的眼睛看来,python正在从父SickBeard进程中妖魔化它,因此它在其管辖范围之外,然后在启动请求时停止。

非常感谢您的帮助和想法! 如果我有任何其他有用的信息,请告诉我。

这不是完全守护进程,但标准Python OS X框架版本中的bin/python可执行文件实际上是一个启动程序,它执行框架中应用程序包内的真正Python可执行文件:

$ /usr/local/bin/python2.7 -c 'import sys; print(sys.executable)'
/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python

可能能够通过更改launchctl plist直接执行该可执行文件来获得您想要的行为。
