Buildbot-在轮询更改问题时进行回溯

Question

我在Windows 7 x64上运行。我遵循了Buildbot上的安装文档，并对我遇到的问题进行了一些研究，但还没有找到解决方案。当我建立部队时，一切都很好。我正在使用GitPoller。当它试图轮询更改时，会抛出异常；为什么？如果我能提供更多信息，请告诉我。以下是我在大师的twist.log上每5分钟得到的内容：

   exceptions.OSError: (2, 'CreateProcess', 'The system cannot find the file specified.')

此外，这是我的配置文件的相关部分：

from buildbot.changes.gitpoller import GitPoller
c['change_source'] = []
c['change_source'].append(GitPoller(
        repourl='https://github.com/solstice333/BuildbotTest.git', 
        branch='master',
        pollinterval=300))

有什么想法吗？

Answer 1

我对HgPoller也有类似的问题。尝试指定git 的完整路径

c['change_source'].append(GitPoller(
    gitbin='full/path/to/git.exe',
    repourl='https://github.com/solstice333/BuildbotTest.git', 
    branch='master',
    pollinterval=300))

我认为twisted有问题-这与相同的错误不起作用

PS Twisted使用win32process.CreateProcess和MSDN谈到它的第一个参数：字符串可以指定要执行的模块的完整路径和文件名，也可以指定部分名称。如果是部分名称，函数将使用当前驱动器和当前目录来完成规范。该函数将不使用搜索路径。

from twisted.internet import utils
utils.getProcessOutputAndValue("hg.exe", ['init', "test_dir"])
