如何在VisualSVN服务器中要求提交消息?
我们在Windows上设置了VisualSVN Server作为我们的Subversion服务器,我们在工作站上使用Ankhsvn + TortoiseSVN作为客户端。
如何configuration服务器来要求提交消息非空?
SVN使用一些钩子来完成这样的任务。
-
start-commit
– 在提交事务开始之前运行,可以用来做特殊权限检查 -
pre-commit
– 在事务结束时运行,但在提交之前运行。 通常用于validation诸如非零长度日志消息的事情。 -
post-commit
– 在事务post-commit
后运行。 可用于发送电子邮件或备份存储库。 -
pre-revprop-change
– 在修改属性更改之前运行。 可以用来检查权限。 - 在修订版本属性更改后运行。 可用于发送电子邮件或备份这些更改。
你需要使用pre-commit
钩子。 你可以用你的平台支持的任何语言自己编写,但是网上有很多脚本。 使用Googlesearch“svn预先提交挂钩要求评论”我发现一对夫妇,看起来他们会适合该法案:
- Perl脚本
- Python脚本
我很高兴你问这个问题。 这是我们用普通Windows Batch编写的预先提交钩子脚本。 如果日志消息less于6个字符,则拒绝提交。 只要把pre-commit.bat放到你的hooks目录下即可。
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
你的问题的技术答案已经给出。 我想添加一个社交答案,即:“通过与团队build立提交消息标准,并让他们同意(或接受)为什么需要expression提交消息的原因”
我见过这么多的提交信息,说“补丁”,“错字”,“修复”或类似的,我已经失去了重要。
真的 – 让大家清楚为什么你需要他们。
例子的原因是:
- 生成的注释 (好吧,这实际上是一个很好的自动工具来执行好的消息,如果我知道他们将(以我的名字)公开可见 – 如果只是为了团队)
- 许可证问题 :以后可能需要知道代码的来源,例如,是否要将许可证更改为代码(有些组织甚至具有提交消息格式的标准 – 也可以自动检查这一点,但是您可以不一定会得到好的提交消息)
- 与其他工具的互操作性 ,例如,与您的版本控制接口并从提交消息中提取信息的bug tracker /问题pipe理系统。
希望有助于,另外还有关于预先提交钩子的技术答案。
什么VisualSVN提供你作为钩子input是“Windows NT命令脚本”,这基本上是batch file。
在batch file中编写if-then-else是非常难看的,可能很难debugging。
它将如下所示(searchpre-commit.bat)(未testing):
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
您需要在path上有一个grep.exe,%1是此存储库的path,%2是将要提交的txn的名称。 还可以查看存储库的hooks目录中的pre-commit.tmpl。
我们使用优秀的CS-Script工具进行预提交,以便我们可以使用我们正在开发的语言编写脚本。下面是一个例子,确保提交的消息超过10个字符,并确保.suo和.user文件未被签入。您还可以testing制表符/空格缩进,或者在签入时执行小代码标准执行,但要小心使脚本执行太多,因为您不希望减慢提交速度。

以下是PowerShell预先提交的示例钩子,它拒绝提交less于25个字符的日志消息。
把pre-commit.bat和pre-commit.ps1放到你的仓库'hooks'文件夹中,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%
这里是一个Windows Shell JScript,你可以通过指定钩子来使用:
%SystemRoot%\System32\CScript.exe //nologo <..path..to..script> %1 %2
这是相当容易阅读,所以继续一个实验。
顺便说一句,在JScript中这样做的原因是它不依赖任何其他工具(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, eg %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."); WScript.Quit(-3); } WScript.Quit(0);
在Windows上使用这个预先提交钩子。 它是用Windows Batch编写的,使用grep命令行实用工具来检查提交长度。
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
记住你需要一个grep的副本,我推荐gnu工具版本 。
注意:这只适用于TortoiseSVN
只需右键单击您的存储库的顶层。 在上下文菜单中selectTortoiseSVN,然后select属性,看到这个对话框:
点击右下angular附近的新buildbutton,然后select日志大小。 input提交和locking所需的字符数(在下面的例子中为10)。
从刚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。
我相信你将不得不设置一个pre-commit钩子来检查消息。
事实上,通过使用Googlesearch得到的第一个结果是perl pre-commit脚本来完成你想要的。
Perl预提交钩子示例(未经testing)
在将提交钩子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:
在TortoiseSVN – >属性属性名称 – 添加/设置tsvn:logminsize
适当。
这当然不能保证服务器上的客户/用户可以select不这样做,但你可以分发svnprops文件,如果你喜欢。 这样,用户不必设置自己的值 – 您可以将其提供给所有用户。
这也适用于像bugtraq:设置链接日志中的问题跟踪的东西。
