为什么我必须使用本地路径而不是SVN绑定的'svn：//'？

Question

我正在使用用SWIG构建的Ruby SVN绑定。 Here's一点教程。

当我这样做

@repository = Svn::Repos.open('/path/to/repository') 

我可以访问存储库的罚款。但是，当我做到这一点

@repository = Svn::Repos.open('svn://localhost/some/path') 

它失败

/SourceCache/subversion/subversion-35/subversion/subversion/libsvn_subr/io.c:2710: 2: Can't open file 'svn://localhost/format': No such file or directory 

当我做这个命令行，我得到的输出

svn ls svn://localhost/some/path 

任何想法，为什么我不能用svn：//协议？

编辑

这里就是我最后做，和它的作品。

require 'svn/ra' 

class SvnWrapper 
    def initialize(repository_uri, repository_username, repository_password) 
    # Remove any trailing slashes from the path, as the SVN library will choke 
    # if it finds any. 
    @repository_uri = repository_uri.gsub(/[\/]+$/, '') 

    # Initialize repository session. 
    @context = Svn::Client::Context.new 
    @context.add_simple_prompt_provider(0) do |cred, realm, username, may_save| 
     cred.username = repository_username 
     cred.password = repository_password 
     cred.may_save = true 
    end 

    config = {} 
    callbacks = Svn::Ra::Callbacks.new(@context.auth_baton) 
    @session = Svn::Ra::Session.open(@repository_uri, config, callbacks) 
    end 

    def ls(relative_path, revision = nil) 
    relative_path = relative_path.gsub(/^[\/]+/, '').gsub(/[\/]+$/, '') 
    entries, properties = @session.dir(relative_path, revision) 

    return entries.keys.sort 
    end 

    def info(relative_path, revision = nil) 
    path = File.join(@repository_uri, relative_path) 
    data = {} 

    @context.info(path, revision) do |dummy, infoStruct| 
     # These values are enumerated at http://svn.collab.net/svn-doxygen/structsvn__info__t.html. 
     data['url'] = infoStruct.URL 
     data['revision'] = infoStruct.rev 
     data['kind'] = infoStruct.kind 
     data['repository_root_url'] = infoStruct.repos_root_url 
     data['repository_uuid'] = infoStruct.repos_UUID 
     data['last_changed_revision'] = infoStruct.last_changed_rev 
     data['last_changed_date'] = infoStruct.last_changed_date 
     data['last_changed_author'] = infoStruct.last_changed_author 
     data['lock'] = infoStruct.lock 
    end 

    return data 
    end 
end 

享受。

svn命令是一个客户端。它使用多种协议（http（s）：//，svn：//和file：///）与Subversion 服务器进行通信。

Repos.open是一个存储库函数（很像svnadmin）。它直接在数据库上运行，并且不使用客户端协议与服务器进行通信。
