仅从在线 SVN 存储库中手动删除最新版本？

Question

这样做：git svn dcommit committing wrong file?, now I have one - the latest - revision on the SVN server-side repository wrong; I'd like to delete it. I am aware I could do svnadmin dump/filter/load as per How do I fix a repository with one broken revision?，但我希望有一个更简单的解决方案。

所以我尝试了这个测试：

cd /tmp
svnadmin create newRepo
svn co file:///tmp/newRepo newRepo-checkout
# Checked out revision 0.
cd newRepo-checkout/

echo aaa > AA.txt
svn add AA.txt 
# A         AA.txt
svn ci -m 'first commit'
# Adding         AA.txt
# Transmitting file data .
# Committed revision 1.

echo bbb > BB.txt
svn ci -m '2ns commit'
svn add BB.txt 
# A         BB.txt
svn ci -m '2nd commit'
# Adding         BB.txt
# Transmitting file data .
# Committed revision 2.

echo ccc > CC.txt
svn add CC.txt 
# A         CC.txt
svn ci -m '3rd commit'
# Adding         CC.txt
# Transmitting file data .
# Committed revision 3.

现在，如果我只删除 db/revs 和 db/revprops 中最新修订版 (3) 的相应文件，我会得到：

$ cd ../newRepo
$ svnadmin verify .
* Verified revision 0.
* Verified revision 1.
* Verified revision 2.
* Verified revision 3.
$ ls db/revprops/0/
0  1  2  3
$ ls db/revs/0/
0  1  2  3  

$ rm db/revs/0/3 
$ rm db/revprops/0/3 

$ svnadmin verify .
* Verified revision 0.
* Verified revision 1.
* Verified revision 2.
svnadmin: No such revision 3

经过一些 grepping 后发现有文件 ./db/txn-current 和 ./db/current 的内容为“3”，所以我尝试更改它：

$ echo 2 > ./db/current
$ echo 2 > ./db/txn-current

$ svnadmin verify .
* Verified revision 0.
* Verified revision 1.
* Verified revision 2.

... 而且 svn co file:///tmp/newRepo newRepo-checkout2 似乎也有效。

所以我的问题是 - 这是否相当安全，或者是否有更多关于在 SVN 服务器中存储修订的信息？

Answer 1

没有。手动编辑存储库数据库文件永远不会 "reasonably safe"。使用 svn 工具 dump/filter/load 更安全，而且最终可能更容易。
