我们在Windows上将VisualSVN Server设置为我们的Subversion服务器，我们在工作站上使用Ankhsvn + TortoiseSVN作为客户端。
如何配置服务器以要求提交消息为非空？
VisualSVN Server 3.9提供了VisualSVNServerHooks.exe check-logmessage预提交挂钩，可帮助您拒绝空或短日志消息的提交。有关说明，请参阅文章KB140: Validating commit log messages in VisualSVN Server。
除了内置的VisualSVNServerHooks.exe，VisualSVN Server和SVN通常使用number of hooks来完成这样的任务。
start-commit - 在提交事务开始之前运行，可用于执行特殊权限检查pre-commit - 在交易结束时运行，但在提交之前。通常用于验证诸如非零长度日志消息之类的内容。post-commit - 在交易提交后运行。可用于发送电子邮件或备份存储库。pre-revprop-change - 在修订版属性更改之前运行。可用于检查权限。post-revprop-change - 在修改属性更改后运行。可用于通过电子邮件发送或备份这些更改。你需要使用pre-commit钩子。您可以使用您的平台支持的任何语言自己编写，但Web上有许多脚本。谷歌搜索“svn precommit挂钩要求评论”我发现一对看起来像他们适合该法案：
在将提交挂钩添加到我的服务器之前，我只是将svnprops分发给TortoiseSVN客户端。
所以，作为替代方案：
在TortoiseSVN - >属性属性名称 - 适当添加/设置tsvn:logminsize。
这当然不能保证在服务器上，因为客户端/用户可以选择不这样做，但是如果你愿意，你可以分发svnprops文件。这样，用户就不必设置自己的值 - 您可以将它们提供给所有用户。
这也适用于bugtraq：设置以链接日志中的问题跟踪内容。
我很高兴你问这个问题。这是我们用常见的Windows Batch编写的预提交钩子脚本。如果日志消息少于6个字符，则拒绝提交。只需将pre-commit.bat放入hooks目录即可。
预commit.bat
setlocal enabledelayedexpansion
set REPOS=%1
set TXN=%2
set SVNLOOK="%VISUALSVN_SERVER%\bin\svnlook.exe"
SET M=
REM Concatenate all the lines in the commit message
FOR /F "usebackq delims==" %%g IN (`%SVNLOOK% log -t %TXN% %REPOS%`) DO SET M=!M!%%g
REM Make sure M is defined
SET M=0%M%
REM Here the 6 is the length we require
IF NOT "%M:~6,1%"=="" goto NORMAL_EXIT
:ERROR_TOO_SHORT
echo "Commit note must be at least 6 letters" >&2
goto ERROR_EXIT
:ERROR_EXIT
exit /b 1
REM All checks passed, so allow the commit.
:NORMAL_EXIT
exit 0
已经给出了您的问题的技术答案。我想添加社交答案，即：“通过与您的团队建立提交消息标准并让他们同意（或接受）为什么需要表达性提交消息的原因”
我看过很多提交消息，上面写着“补丁”，“拼写错误”，“修复”或类似错误。
真的 - 让每个人都清楚你为什么需要它们。
原因的例子是：
希望有帮助，除了关于precommit钩子的技术答案。
这是一个两部分示例Batch + PowerShell预提交挂钩，它拒绝提交少于25个字符的日志消息。
将pre-commit.bat和pre-commit.ps1放入您的存储库hooks文件夹，例如C:\Repositories\repository\hooks\
预commit.ps1
# Store hook arguments into variables with mnemonic names
$repos = $args[0]
$txn = $args[1]
# Build path to svnlook.exe
$svnlook = "$env:VISUALSVN_SERVER\bin\svnlook.exe"
# Get the commit log message
$log = (&"$svnlook" log -t $txn $repos)
# Check the log message contains non-empty string
$datalines = ($log | where {$_.trim() -ne ""})
if ($datalines.length -lt 25)
{
# Log message is empty. Show the error.
[Console]::Error.WriteLine("Commit with empty log message is prohibited.")
exit 3
}
exit 0
预commit.bat
@echo off
set PWSH=%SystemRoot%\System32\WindowsPowerShell\v1.0\powershell.exe
%PWSH% -command $input ^| %1\hooks\pre-commit.ps1 %1 %2
if errorlevel 1 exit %errorlevel%
注1：pre-commit.bat是唯一可以被VisualSVN调用的，然后pre-commit.ps1是由pre-commit.bat调用的那个。
注2：pre-commit.bat也可能被命名为pre-commit.cmd。
注3：如果你试验一些重音字符和[Console]::Error.WriteLine输出的编码问题，那么将chcp 1252加到pre-commit.bat，@echo off之后的下一行。
VisualSVN为您提供的钩子是“Windows NT命令脚本”，它们基本上是批处理文件。
在批处理文件中编写if-then-else非常难看，可能很难调试。
它将类似于以下内容（搜索pre-commit.bat）（未测试）：
SVNLOOK.exe log -t "%2" "%1" | grep.exe "[a-zA-Z0-9]" > nul || GOTO ERROR
GOTO OK
:ERROR
ECHO "Please enter comment and then retry commit!"
exit 1
:OK
exit 0
您需要路径上的grep.exe，％1是此存储库的路径，％2是要提交的txn的名称。还要查看存储库的hooks目录中的pre-commit.tmpl。
我们使用优秀的CS-Script工具进行预提交钩子，以便我们可以用我们正在开发的语言编写脚本。这是一个确保提交消息超过10个字符的示例，并确保.suo和.user文件未签入。您还可以测试选项卡/空格缩进，或在签入时执行小代码标准，但要小心使您的脚本执行太多操作，因为您不希望减慢提交速度。

这是一个Windows Shell JScript，您可以通过将钩子指定为：
%SystemRoot%\System32\CScript.exe //nologo <..path..to..script> %1 %2
这很容易阅读，所以继续进行实验。
顺便说一句，在JScript中这样做的原因是它不依赖于任何其他工具（Perl，CygWin等）来安装。
if (WScript.Arguments.Length < 2)
{
WScript.StdErr.WriteLine("Repository Hook Error: Missing parameters. Should be REPOS_PATH then TXN_NAME, e.g. %1 %2 in pre-commit hook");
WScript.Quit(-1);
}
var oShell = new ActiveXObject("WScript.Shell");
var oFSO = new ActiveXObject("Scripting.FileSystemObject");
var preCommitStdOut = oShell.ExpandEnvironmentStrings("%TEMP%\\PRE-COMMIT." + WScript.Arguments(1) + ".stdout");
var preCommitStdErr = oShell.ExpandEnvironmentStrings("%TEMP%\\PRE-COMMIT." + WScript.Arguments(1) + ".stderr");
var commandLine = "%COMSPEC% /C \"C:\\Program Files\\VisualSVN Server\\bin\\SVNLook.exe\" log -t ";
commandLine += WScript.Arguments(1);
commandLine += " ";
commandLine += WScript.Arguments(0);
commandLine += "> " + preCommitStdOut + " 2> " + preCommitStdErr;
// Run Synchronously, don't show a window
// WScript.Echo("About to run: " + commandLine);
var exitCode = oShell.Run(commandLine, 0, true);
var fsOUT = oFSO.GetFile(preCommitStdOut).OpenAsTextStream(1);
var fsERR = oFSO.GetFile(preCommitStdErr).OpenAsTextStream(1);
var stdout = fsOUT && !fsOUT.AtEndOfStream ? fsOUT.ReadAll() : "";
var stderr = fsERR && !fsERR.AtEndOfStream ? fsERR.ReadAll() : "";
if (stderr.length > 0)
{
WScript.StdErr.WriteLine("Error with SVNLook: " + stderr);
WScript.Quit(-2);
}
// To catch naught commiters who write 'blah' as their commit message
if (stdout.length < 5)
{
WScript.StdErr.WriteLine("Please provide a commit message that describes why you've made these changes.");

}

在Windows上使用此预提交挂钩。它是用Windows Batch编写的，并使用grep命令行实用程序来检查提交长度。
svnlook log -t "%2" "%1" | c:\tools\grep -c "[a-zA-z0-9]" > nul
if %ERRORLEVEL% NEQ 1 exit 0
echo Please enter a check-in comment 1>&2
exit 1
请记住，你需要一份grep副本，我推荐gnu tools version。
注意：这仅适用于TortoiseSVN
只需右键单击存储库的顶级。在上下文菜单中选择TortoiseSVN，然后选择Properties，以查看此对话框：
单击右下角附近的“新建”按钮，然后选择“日志大小”。输入提交和锁定所需的字符数（下例中为10）。
从刚修改的顶级目录执行提交。现在，您的存储库要求所有用户在提交更改之前进行注释。
