Question

我正在使用化石作为某种增量备份数据库。到目前为止，除了清除旧条目外，它的效果非常好。由于这都是自动化的，并且意味着简单，所有签入/回滚都在主干上工作。

现在我尝试添加清除旧签到的选项，但我无法，总是遇到错误消息：

cannot purge the current checkout

也许我正在以错误的方式使用清除，但我无法找到正确的方法。目前我添加一个标签到我要删除的签到，并尝试清除它们不起作用。从那些签入中删除主干标签没有任何区别。由于化石需要vvar表进行此操作，因此无法在我的本地存储库关闭时运行清除。

我做了一个例子来说明：

我所做的只是初始化一个新的化石库;添加单个文件并提交; rmeove文件并再次提交;并尝试清除添加文件的检查。

编辑：我使用化石版本1.32和1.33

测试了这个

错误消息似乎说明了一切，确实：您无法清除当前结帐（在时间轴中标记为*CURRENT*的签到），或其后代之一。来自the help for the purge command（强调我的）：

移动由TAGS 及其所有后代标识的签到超出存储库（...）

在执行清除操作之前，解决方案是update或checkout到不同的签入，不依赖于签入清除。

如何清除化石当前分支的单一签到？
