【问题描述】：
我正在尝试使用 Mercurial 作为 Subversion 的前端，并且对保持所有分支等完好无损非常感兴趣，以便我可以看到常见的更改等。
但是，我所有的 subversion 存储库都为 mercurial 创建了相当大的问题（不幸的是，1.8 和 TortoiseHg 2.0，ppa 似乎已经删除了旧版本......）。这些问题五花八门，让人难以一一列举（或弄清楚）。
如何跳过 hg clone 或 hg pull 抱怨的 svn 修订版？还是我只需要递归地获得越来越少的修订，直到获得成功的克隆？
另外，我尝试通过从 svn 导出补丁并将其应用到我的工作目录来解决此问题；发生完全相同的问题（但至少现在我有一些东西要看......）
我遇到的问题（但不是专门针对问题的主题...）
现有文件覆盖尝试：
由hg init实现，设置svn url和hg pull
pulling from svn+http://subversion/src/...
[r5061] StephenK: Updated properties
/home/stephenk/hgsubversion/hgsubversion/wrappers.py:337: DeprecationWarning: BaseException.message has been deprecated as of Python 2.6
ui.status('%s\n' % e.message)
This Subversion server is older than 1.4.0, and cannot satisfy replay requests.
In light of that, I'll fall back and do diffs, but it won't do as good a job. You should really upgrade your server.

我在 ubuntu 上，真的很想有一个 ppa 来为我管理它，并且对这种互操作性感到沮丧。我在想我可能得试试 hg+git+svn 双桥之类的东西
【问题讨论】：
-
您能否更具体地说明您遇到的问题类型？
-
我已经添加了到目前为止我遇到的两个问题......如果你能简洁地回答它们（我已经“找到”修复，但没有一个容易遵循或保证工作...... .) 然后让我知道，我会提出另一个问题...
-
看起来这可能是我们的 svn (1.3.2!) 存储库的问题：bitbucket.org/durin42/hgsubversion/issue/279/…。我们有望在本月底更新到 1.6...
