CruiseControl.rb的又一个Bug

我遇到的问题如下：

执行：
./cruise build test_cc_01
的时候，会出现以下错误？字面上看是连接SVN没权限，但我试过好多SVN，而且之前我已经通过./cruise add方法将SVN的代码拉下来过了，难道它不记得密码？
即便它不记得密码，我也试过./cruise build test_cc_01 --username zheng.cuizh --password PPPPPPP
也不行，
我还试过在test_cc_01项目的配置文件cruise_config.rb中，加入如下代码：

  project.source_control.username = 'zheng.cuizh'
  project.source_control.password = 'PPPPPPP'

还是不行！

执行时候所有的代码和错误提示如下：

[error] svn: OPTIONS of 'https://roadrunner.googlecode.com/svn/trunk': authorization failed (https://roadrunner.googlecode.com) 

我尝试跟踪到负责读写配置文件的CC的那块代码，

发现CC加载一个项目的配置文件是在这个方法里面完成的：

  def write_config_example(project)
    config_example = File.join(RAILS_ROOT, 'config', 'cruise_config.rb.example')
    config_in_subversion = File.join(project.path, 'work', 'cruise_config.rb')
    cruise_config = File.join(project.path, 'cruise_config.rb')
    if File.exists?(config_example) and not File.exists?(config_in_subversion)
      FileUtils.cp(config_example, cruise_config)
    end
  end

我怀疑config_in_subversion 这个文件中的用户名和密码没有起作用。

全文搜索username和password,在./lib/subversioni.rb文件中找到两处代码：

  def checkout(revision = nil, stdout = $stdout)
    @url or raise 'URL not specified'

    options = [@url, path]
    # =>zheng.cuizh:add a patch start
    # options << "--username" << @username if @username
    # options << "--password" << @password if @password
    # =>zheng.cuizh:add end
    options << "--revision" << revision_number(revision) if revision

    # need to read from command output, because otherwise tests break
    svn('co', options) do |io| 
      begin
        while line = io.gets
          stdout.puts line
        end
      rescue EOFError
      end
    end
  end

  def svn(operation, arguments, options = {}, &block)
    command = ["svn"]
    command << "--non-interactive" unless @interactive
    command << operation
    command += arguments.compact

    # => zheng.cuizh:add a patch start:
    command += ['--username', @username, '--password', @password] if @username and @password
    # => zheng.cuizh:add end.
    command
    
    execute_in_local_copy(command, options, &block)
  end

这个RB文件中，好好读一下可以发现svn是执行svn命令的方法，我之前报错就说svn在checkout的时候没有权限，很可能是执行svn("checkout",options...)这个类似的代码时，没有把用户名和密码传过去。

在网上搜索了一下这段代码，居然找到了一个哥们和我遇到同样的问题，他的文章如下：
[url]http://www.practicalguile.com/2008/02/02/using-cruisecontrolrb-with-repositories-without-anonymous-access/
[/url]
他的解决方案如下：

     options = [@url, target_directory]
-    options << "--username" << @username if @username
-    options << "--password" << @password if @password
     options << "--revision" << revision_number(revision) if revision

     command << "--non-interactive" unless @interactive
     command << operation
     command += options.compact.flatten
+    command += ['--username', @username, '--password', @password] if @username and @password
     command

搞定！
