为什么我必须使用本地路径而不是'svn://'与SVN绑定?

我正在使用使用SWIG构建的Ruby SVN绑定。 Here's一个小教程。

当我这样做时

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

我可以很好地访问存储库。但是当我这样做时

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

失败了

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

当我从命令行执行此操作时,我会得到输出

svn ls svn://localhost/some/path

为什么我不能使用svn://协议?

的任何想法

这是我最终做的事情,并且有效。

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命令是客户端。它使用多个协议(http(s)://,svn://和file:///)与Subversion 服务器进行通信。

Repos.open是一个存储库函数(就像svnadmin一样)。它直接在数据库上运行,不使用客户端协议与服务器通信。
