这篇文章继续介绍Subverison Edge中如何使用SVN的Hook机制。

# 环境和事前准备 #

Subversion Edge环境准备和仓库创建的操作可参看如下文章：

# SVN的hook机制 #

关于SVN的hook使用，详细可参看如下文章：

*  [https://blog.csdn.net/liumiaocn/article/details/81942161][https_blog.csdn.net_liumiaocn_article_details_81942161]

# 设定提交时的Comment格式 #

在Subversion Edge中设定Hook可以在创建的仓库的时候，也可以在创建之后，在仓库列表页面选中相应的仓库，点击info按钮

选中pre-commit模版，点击edit按钮

缺省此模版的信息如下所示

#!/bin/sh
    
    # POST-COMMIT HOOK
    #
    # The post-commit hook is invoked after a commit.  Subversion runs
    # this hook by invoking a program (script, executable, binary, etc.)
    # named 'post-commit' (for which this file is a template) with the 
    # following ordered arguments:
    #
    #   [1] REPOS-PATH   (the path to this repository)
    #   [2] REV          (the number of the revision just committed)
    #   [3] TXN-NAME     (the name of the transaction that has become REV)
    #
    # The default working directory for the invocation is undefined, so
    # the program should set one explicitly if it cares.
    #
    # Because the commit has already completed and cannot be undone,
    # the exit code of the hook program is ignored.  The hook program
    # can use the 'svnlook' utility to help it examine the
    # newly-committed tree.
    #
    # On a Unix system, the normal procedure is to have 'post-commit'
    # invoke other programs to do the real work, though it may do the
    # work itself too.
    #
    # Note that 'post-commit' must be executable by the user(s) who will
    # invoke it (typically the user httpd runs as), and that user must
    # have filesystem-level permission to access the repository.
    #
    # On a Windows system, you should name the hook program
    # 'post-commit.bat' or 'post-commit.exe',
    # but the basic idea is the same.
    # 
    # The hook program typically does not inherit the environment of
    # its parent process.  For example, a common problem is for the
    # PATH environment variable to not be set to its usual value, so
    # that subprograms fail to launch unless invoked via absolute path.
    # If you're having unexpected problems with a hook program, the
    # culprit may be unusual (or missing) environment variables.
    # 
    # Here is an example hook script, for a Unix /bin/sh interpreter.
    # For more examples and pre-written hooks, see those in
    # the Subversion repository at
    # http://svn.apache.org/repos/asf/subversion/trunk/tools/hook-scripts/ and
    # http://svn.apache.org/repos/asf/subversion/trunk/contrib/hook-scripts/
    
    
    REPOS="$1"
    REV="$2"
    TXN_NAME="$3"
    
    mailer.py commit "$REPOS" "$REV" /path/to/mailer.conf

我们这里进行如下修改

#!/bin/sh
    
    REPOS="$1"
    TXN="$2"
    
    LOG_INFO=`svnlook log -t "$TXN" "$REPOS"`
    
    # check empty comment
    if [ _"$LOG_INFO" = _"" ]; then
      echo "" 1>&2
      echo "   ## LOG CHECK : NG: [$LOG_INFO] does not match the rules." 1>&2
      exit 1
    fi
    
    # check log format with # :
    TICKET_NO=`echo "$LOG_INFO" |sed s/#//g |awk -F : '{print $1}'`
    COMMENT_MSG=`echo "$LOG_INFO" |sed s/#//g |awk -F : '{print $2}'`
    if [ _"$TICKET_NO" = _"" -o _"$COMMENT_MSG" = _"" ]; then
        echo "" 1>&2
        echo "   ## LOG CHECK : NG: [$LOG_INFO] does not match the rules." 1>&2
        echo "      Sample : # BUG1002: feature F1001 bug fixed" 1>&2
        exit 1
    fi
    
    # pre-commit check passed.
    exit 0

# 客户端验证 #

连续执行两次空comment都成功了

原因是上述的模版只是模版，而没有真正起作用（详细参看文初的链接文章的说明），在Subversion Edge中还提供了rename的功能，实际就是真正将模版起效的过程，选中pre-commit模版，点击rename按钮

将.tmpl的后缀删除，点击OK按钮并保存

再次从客户端提交一个没有comment的变更，可以看到pre-comment的hook机制已经生效。
