运行 SVNPoller 时生成错误消息

Question

我正在尝试在我的组织中设置 Buildbot，但 SVNPoller 出现问题。

每当 subversion 存储库更改时，SVNPoller 都会正确地识别这一点，但随后会失败并显示以下错误消息：

SVNPoller 失败 [失败实例：Traceback: :changes.project 可能不为 NULL

我很确定我犯了一个错误，但此错误消息并没有真正帮助，因此我们将不胜感激。

ma​​ster.cfg：

svn_poller = SVNPoller(
                    svnurl=source_code_svn_url,
                    pollinterval=60*10, # seconds
                    svnuser='job_guest',
                    svnpasswd='job_guest',
                    svnbin='/usr/bin/svn'
)
c['change_source'] = [ svn_poller ]

Answer 1

我找到了导致错误的原因：使用 SVNPoller 时，必须同时设置项目参数！

svn_poller = SVNPoller(
                    project='project',        
                    svnurl=source_code_svn_url,
                    pollinterval=60*10, # seconds
                    svnuser='job_guest',
                    svnpasswd='job_guest',
                    svnbin='/usr/bin/svn'
)
c['change_source'] = [ svn_poller ]

Answer 2

事实上，如果您使用 0.8 或更高版本，即使您不想，它们也会要求您指定一个项目；因为没有默认值。

只需按照其他用户的建议，在轮询器中添加 project = 'myproject' 即可，然后就可以开始了。
