UUID

SVN崩溃了，换了一个服务器，relocate操作时遇到“The respository at '...' has uuid '...', but the WC has '...'”的问题。

  网上搜到同类“Repository UUID '...' doesn't match expected UUID'...'”问题

解决方法：

1、UUID是respository创建时自动生成的一个随机数，SVN Client利用UUID判断是否为同一个resp。一般遇到UUID不同时，需要重新Checkout.

2、如果我们一定要改变UUID的话（这不正是我们想要的吗），注意，这是修改Server上resp的UUID：
1.5版本之后

$ svnlook uuid /var/svn/repos
cf2b9d22-acb5-11dc-bc8c-05e83ce5dbec
$ svnadmin setuuid /var/svn/repos   # generate a new UUID
$ svnlook uuid /var/svn/repos
3c3c38fe-acc0-11dc-acbc-1b37ff1c8e7c
$ svnadmin setuuid /var/svn/repos \
           cf2b9d22-acb5-11dc-bc8c-05e83ce5dbec  # restore the old UUID
$ svnlook uuid /var/svn/repos
cf2b9d22-acb5-11dc-bc8c-05e83ce5dbec
$

For folks using versions of Subversion earlier than 1.5, these tasks are a little more complicated. You can explicitly set a repository's UUID by piping a repository dump file stub that carries the new UUID specification through svnadmin load --force-uuid REPOS-PATH.

$ svnadmin load --force-uuid /var/svn/repos <<EOF
SVN-fs-dump-format-version: 2

UUID: cf2b9d22-acb5-11dc-bc8c-05e83ce5dbec
EOF
$ svnlook uuid /var/svn/repos
cf2b9d22-acb5-11dc-bc8c-05e83ce5dbec
$

3、也可以直接修改work copy的UUID。本地WC的UUID写在文件
.svn/entries文件中
