SVN post-commit钩子发送消息给客户端 [英] SVN post-commit hook sending a message back to client

问题描述

我正在写在bash后提交脚本，我想传递消息回谁在作出承诺的客户端。然而

I'm writing a post-commit script in bash, and I'd like to pass messages back to the client who's making a commit. However

echo my message >&2

不使它返回给客户端。它甚至有可能将消息发送回一个post-commit钩子？

isn't making it back to the client. Is it even possible to send messages back with a post-commit hook?

推荐答案

Condering一个的 post-commit钩子做：

Condering a post-commit hook does:

任何输出到stderr的钩子将被编组回客户端，使其更容易诊断钩子的失败。

anything that the hook printed to stderr will be marshalled back to the client, making it easier to diagnose hook failures.

您可以检查，如果这不是一个简单的问题帖：

you can check if this isn't a simple quote issue:

echo "my message" >&2

您可以在那些钩范例任何回声到＆GT;＆安培; 2 包括引号

You can see in those hook examples that any echo to >&2 includes quotes.

在重定向的 bash的章节还包括与报价的例子。

The bash chapter on redirection also includes examples with quotes.

然而，如在 PMOD 的细节=htt​​p://stackoverflow.com/a/8427369/ 6309的他的回答，除非脚本的退出状态由0不同，使用中所示的标准错误信息将不可见=htt​​p://serverfault.com/a/386219/ 783>颠覆post-commit钩子：打印错误的信息，即用户可以看到

However, as pmod details in his answer, that stderr message won't be visible unless the exit status of the script differs from 0, as illustrated in "subversion post-commit hook: print an error message that the user can see?"

#!/bin/bash
echo "test" >&2
exit 1
