“未找到文件"在 Subversion 中恢复已删除的目录时
我想将我的项目回滚到更早的阶段，所以我尝试了这个:
I wanted to roll back my project to an earlier stage, so I tried this:
svn rm -m "clear out mistakes rolling back" ^/MyProject/trunk
svn copy -m "roll back" -r 165 ^/MyProject/trunk ^/MyProject/trunk
但我一直收到错误找不到文件:修订版 265，路径 '/MyProject/trunk'".265 是 HEAD，但我不知道为什么它会在现有修订中寻找目标目录，而不是简单地创建它.
But I kept getting the error "File not found: revision 265, path '/MyProject/trunk'". 265 is HEAD, but I don't know why it would be looking for the target directory in an existing revision, rather than simply creating it.
显然问题出在 ^ 符号上，因为使用完整的 URL 可以正常工作:
Apparently the problem was with the ^ notation, because using complete URLs worked OK:
svn copy -m "roll back" <full URL>/MyProject/trunk@165 <full URL>/MyProject/trunk
但我最近使用 ^ 符号通过类似的复制操作创建了一个分支.(客户端是命令行 svn 1.6.17.)那么，为什么在这种情况下它不起作用?
But I've used the ^ notation recently to make a branch via a similar copy operation. (The client is command-line svn 1.6.17.) So, why did it not work in this case?
我认为问题在于-r"和@rev":它们的含义不同.
I think the problem is with "-r " and "@rev": they have different meaning.
-r rev <path> --- 操作修订 --- 表示 @HEAD 处于修订版rev"的状态(例如，如果 @HEAD 不存在，则命令失败；如果它是从修订版 > rev 中的某个路径 2 替换/复制的，则状态为 path2@rev)
-r rev <path> --- operative revision --- means the state in which was @HEAD was at revision "rev" (e.g. if @HEAD doesn't exist the command fails; if it was replaced/copied from some path2 in revision > rev, then the state is path2@rev)
path@rev ---peg revision --- 表示路径的状态正好在修订版上(那么路径是否存在于 HEAD 并不重要，即使 path@HEAD 是由path2替换，状态为path@rev).
path@rev ---peg revision --- means the state of path exactly at revision rev (then it doesn't matter if path exists at HEAD, and even if path@HEAD is replaced from path2, the state is path@rev).
