svn - 如何防止用户将二进制文件提交到颠覆？

Question

我有一个任性的用户，他顽固地坚持将他的二进制文件(可执行文件、DLL)提交到我们的 subversion 存储库中。我会进去删除它们，但当然没有什么东西真的从颠覆中删除了。

虽然有时我们需要提交二进制文件，但我不希望用户将其作为例行公事。我可以设置一个忽略属性，但这不会阻止用户提交二进制文件，如果他们真的确定的话。我想做的是能够逐个目录地控制提交指定文件类型的能力，特别是 .exe 和 .dll 文件。

有没有办法在 SVN 中做到这一点？如果有什么不同，我们使用的是 VisualSVN 服务器和 TortoiseSVN。

蒂姆:

你可以试试这个 python 钩子(Hook)脚本。它(松散地)基于上面的那个，但允许拒绝路径的正则表达式模式，并允许通过有一个开始的行来覆盖检查

覆盖:

在日志消息中。它使用新的 python 打印语法，因此它需要一个相当新的 python 版本(2.6+？)。
