如何使用SharpSVN访问预提交挂钩中的文件信息 [英] How to access file information in a pre-commit hook using SharpSVN

问题描述

总体来说，我对SharpSVN和SVN还是陌生的.我正在尝试实现一个预提交钩子，该钩子在用户提交某种类型的XML文件时提供；在允许提交文件之前，我将需要截取文件并对其进行分析，以确保它们包含某些元素.

I am new to SharpSVN and SVN in general. I am trying to implement a pre-commit hook that when the user commits a certain type of XML file; I am going to need to intercept the file and analyze it to ensure they included certain elements before I allow the file to be committed.

由于SVN似乎提交了两个参数；仓库路径和交易；我将需要使用这两项来拦截文件.有人知道我需要在SharpSVN中使用这两个参数来获取文件信息吗?

Since it seems that SVN submits two arguments; the repository path and the transaction; I will need to use these two items to intercept the file. Does anyone know what I need to use in SharpSVN to get file information based on these two parameters?

谢谢， 跳蚤#

推荐答案

您可以使用内置的SvnLookClient来实现.

You can do this by using the builtin SvnLookClient.

要使用此功能，首先需要一个SvnLookOrigin. SharpSvn包含标准参数解析，可以知道"将哪些参数传递给每种类型的挂钩.这使您可以访问此SvnLookOrigin:

To use this, first of all you need a SvnLookOrigin. SharpSvn contains standard argument parsing that 'knows' what arguments are passed to each type of hook. This gives you access to this SvnLookOrigin:

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

根据已解析的参数获取更改的文件和这些文件的内容

Getting the changed files and contents of those files based on the parsed arguments

using (SvnLookClient cl = new SvnLookClient())
{
    Collection<SvnChangedEventArgs> changedItems;
    cl.GetChanged(ha.LookOrigin, out changedItems);

    foreach(var item in changedItems)
    {
        if(!IsXmlFile(item)) continue;

        using(MemoryStream ms = new MemoryStream())
        {
            cl.Write(ha.LookOrigin, item.Path, stream);

            VerifyXMLStream(stream);
        }
    }
}

编辑:写入Console.Error和Environment.Exit(1)以报告错误(退出为非null).

Edit: Write to Console.Error and Environment.Exit(1) to report errors (exit non-null).
