有时需要对提交的版本，进行日志编辑，但操作后经常会有以下弹出错误

DAV request failed; it's possible that the repository's pre-revprop-change hook

either failed or is non-existent At least one property change failed; repository is uncahnaged

Error setting property "log":

Repository has not been enabled to accept revision propchanges;

ask the administrator to create a pre-revprop-change hook

解决办法如下：

进入visualsvn管理界面

找到你的项目目录，右击选择中 “所有任务-》Manage Hooks”

选择 “Pre-revision property change hook”，然后点击下面的编辑

敲两个回车，然后点OK关闭就可以了。

其实就是在项目目录里的hooks子目录下创建了一个空白pre-revprop-change.cmd

我试过了，是成功的。

以下是原文解决办法

From VisualSVN Manager, right click on your repo and select “All Tasks \ Manage Hooks”. Select “Pre-revision property change hook” and edit that – enter a couple of blank lines then click ok. Done. The hook will now be listed in bold indicating it exists.
