很多程序员不爱写注释，特别是svn提交的时候，文件做了什么修改都没有一个简单的备注，往往都是直接提交，这样是非常不利于团队开发的。所以就有了svn提交的时候，强制修改文件的备注。
步骤如下：
1、先找到对应项目的svn版本库hooks
sudo find / -name hooks
2、假设进入test_wx项目下面的svn版本库
复制一份pre-commit.tmpl文件
cp pre-commit.tmpl pre-commit
修改pre-commit的权限
chmod +x pre-commit
3、编辑pre-commit文件
vim pre-commit
修改后代码如下
# If the hook program exits with success, the txn is committed; but # if it exits with failure (non-zero), the txn is aborted, no commit # takes place, and STDERR is returned to the client. The hook # program can use the 'svnlook' utility to help it examine the txn. # # On a Unix system, the normal procedure is to have 'pre-commit' # invoke other programs to do the real work, though it may do the # work itself too. # # *** NOTE: THE HOOK PROGRAM MUST NOT MODIFY THE TXN, EXCEPT *** # *** FOR REVISION PROPERTIES (like svn:log or svn:author). *** # # This is why we recommend using the read-only 'svnlook' utility. # In the future, Subversion may enforce the rule that pre-commit # hooks should not modify the versioned data in txns, or else come # up with a mechanism to make it safe to do so (by informing the # committing client of the changes). However, right now neither # mechanism is implemented, so hook writers just have to be careful. # # Note that 'pre-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 # 'pre-commit.bat' or 'pre-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" TXN="$2" # Make sure that the log message contains some text. SVNLOOK=/usr/bin/svnlook LOGMSG=`$SVNLOOK log -t "$TXN" "$REPOS" | grep "[a-zA-Z0-9]" | wc -c` if [ "$LOGMSG" -lt 5 ]; then echo -e "注释信息不能为空且不少于5个字!" 1>&2 exit 1 fi exit 0
4、无需重启svn服务，直接测试。效果如下
