我如何使用 SharpSVN 访问 SVN 预提交消息？

Question

我看到我所能设置的就是 %repos% 和 %txn%

我如何使用它们来获取提交消息（在我的例子中，这样我可以解析出票号，以便我可以查看它是否存在于错误中提交之前的数据库）

Answer 1

我不知道 SharpSVN，但是如果您按照您的描述创建一个钩子脚本，您将获得 %repos% 和 %txn% 作为参数。

通过这些数据，您可以查看给定存储库的事务 (%txn%)。通常您可以通过使用

svnlook -t %txn%  %repo%

然后您将收到日志消息来执行此操作。

所以你应该在 SharpSVN 界面中寻找与 svnlook 等效的东西。

Answer 2

不久前，我为 svnlook.exe 编写了一个 C# 包装器。我使用这个将提交消息发送到错误跟踪器（如果提供了票证 ID）。下面找到它，也许对你有用。

Answer 3

使用最近的 SharpSvn 版本，您可以用来

SvnHookArguments ha; 
if (!SvnHookArguments.ParseHookArguments(args, SvnHookType.PreCommit, false, out ha))
{
    Console.Error.WriteLine("Invalid arguments");
    Environment.Exit(1);  
}

解析预提交挂钩的参数，然后使用

using (SvnLookClient cl = new SvnLookClient())
{
    SvnChangeInfoEventArgs ci;

    cl.GetChangeInfo(ha.LookOrigin, out ci);


    // ci contains information on the commit e.g.
    Console.WriteLine(ci.LogMessage); // Has log message

    foreach (SvnChangeItem i in ci.ChangedPaths)
    {

    }
}

它来获取日志消息、更改的文件等

我刚刚完成了自己构建 Hooks 应用程序的过程，并且不需要 SharpSVN 来查看提交消息。假设您已经为自己构建了一个控制台应用程序，请尝试直接调用 svnlook.exe 的代码：

string repos = args[0];
string txn = args[1];

var processStartInfo = new ProcessStartInfo
{
  FileName = "svnlook.exe",
  UseShellExecute = false,
  CreateNoWindow = true,
  RedirectStandardOutput = true,
  RedirectStandardError = true,
  Arguments = String.Format("log -t \"{0}\" \"{1}\"", txn, repos)
};

Process process = Process.Start(processStartInfo);
string message = process.StandardOutput.ReadToEnd();
process.WaitForExit();
return message;

确保 svnlook.exe 的位置已添加到计算机的路径环境变量中，以便可以从任何位置执行上述内容。
