Subversion post-commit hook用于触发将repo导出到其他目录

标签： python svn version-control subprocess post-commit

我正在尝试为svn编写一个post commit hook脚本，以将存储库导出到多个目录（因此，当您提交代码时，最新版本的代码也会被复制到其他目录中）。例如，我有一个包含4个路径（或目录）A，B，C，D的仓库。我希望如果我在A中提交，那么修订也应该转到B，C，D。同样地，如果我在B中提交，则修订应该转到C，D，同样在C上提交时，它应该反映在D上。

我开始了解提交后但不知道如何使用它。我已经编写了一堆部分代码。也就是说，当我在A中提交时，它会转到B但不会转到C或D，类似地，当我在B上提交它时，它会转到C而不是D.但

我之前没有编写过脚本。我做了一个测试回购测试来测试我的工作。
