如何在Windows环境中用Trac和SVN实现提交后挂接?

时间:2020-03-05 18:59:05  来源:igfitidea点击:

我在带有Trac / SVN的Windows环境中运行,我希望提交到存储库以将其集成到Trac中并关闭SVN注释中提到的错误。

我知道有一些后提交钩子可以做到这一点,但是关于如何在Windows上做到这一点的信息并不多。

有人成功完成了吗?我们要遵循的步骤是什么?

这是我需要在SVN中放置的钩子,但是我不确定在Windows环境中如何执行此操作。

Trac Post Commit Hook

解决方案

回答

发布提交钩子位于"钩子"目录中,无论我们在哪里存储库都位于服务器端。我不知道我们在环境中的什么位置,所以这只是一个例子

例如(视窗):

C:\Subversion\repositories\repo1\hooks\post-commit

例如(llinux / unix):

/usr/local/subversion/repositories/repo1/hooks/post-commit

回答

本杰明的答案很接近,但是在Windows上,我们需要为钩子脚本文件提供可执行的扩展名,例如.bat或者.cmd。我使用.cmd。我们可以采用模板脚本(它们是unix shell脚本,shell脚本)并将其转换为.bat / .cmd语法。

但是要回答与Trac集成的问题,请遵循以下步骤。

  • 确保Python.exe在系统路径上。这将使生活更轻松。
  • 在\ hooks文件夹中创建post-commit.cmd。这是Subversion将在提交后事件上执行的实际钩子脚本。
@ECHO OFF

:: 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)
::
:: 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.collab.net/repos/svn/trunk/tools/hook-scripts/ and
:: http://svn.collab.net/repos/svn/trunk/contrib/hook-scripts/

setlocal

:: Debugging setup
:: 1. Make a copy of this file.
:: 2. Enable the command below to call the copied file.
:: 3. Remove all other commands
::call %~dp0post-commit-run.cmd %* > %1/hooks/post-commit.log 2>&1

:: Call Trac post-commit hook
call %~dp0trac-post-commit.cmd %* || exit 1

endlocal
  • 在\ hooks文件夹中创建trac-post-commit.cmd:
@ECHO OFF
::
:: Trac post-commit-hook script for Windows
::
:: Contributed by markus, modified by cboos.

:: Usage:
::
:: 1) Insert the following line in your post-commit.bat script
::
:: call %~dp0\trac-post-commit-hook.cmd %1 %2
::
:: 2) Check the 'Modify paths' section below, be sure to set at least TRAC_ENV

setlocal

:: ----------------------------------------------------------
:: Modify paths here:

:: -- this one *must* be set
SET TRAC_ENV=D:\projects\trac\membershipdnn

:: -- set if Python is not in the system path
SET PYTHON_PATH=

:: -- set to the folder containing trac/ if installed in a non-standard location
SET TRAC_PATH=
:: ----------------------------------------------------------

:: Do not execute hook if trac environment does not exist
IF NOT EXIST %TRAC_ENV% GOTO :EOF

set PATH=%PYTHON_PATH%;%PATH%
set PYTHONPATH=%TRAC_PATH%;%PYTHONPATH%

SET REV=%2

:: Resolve ticket references (fixes, closes, refs, etc.)
Python "%~dp0trac-post-commit-resolve-ticket-ref.py" -p "%TRAC_ENV%" -r "%REV%"

endlocal
  • 在\ hooks文件夹中创建trac-post-commit-resolve-ticket-ref.py。我使用了EdgeWall的相同脚本,只是我将其重命名以更好地阐明其目的。

回答

好了,现在我已经花了很多时间在弄清一切之后发布我的经验,并感谢Craig使我走上正确的道路。这是我们需要做的(至少在SVN v1.4和Trac v0.10.3中):

  • 找到要为其启用"提交后挂接"的SVN存储库。
  • SVN存储库中有一个名为hooks的目录,我们将在其中放置发布后提交钩子。
  • 创建一个文件post-commit.bat(这是SVN post commit自动调用的批处理文件)。
  • 将以下代码放入post-commit.bat文件中(这将调用post commit cmd文件,并传入SVN自动传递的参数,其中%1是存储库,%2是已提交的修订。

%〜dp0 \ trac-post-commit-hook.cmd%1%2

  • 现在创建trac-post-commit-hook.cmd文件,如下所示:
@ECHO OFF
 ::
 :: Trac
  post-commit-hook script for
  Windows
 ::
 :: Contributed by
  markus, modified by cboos.
 
 ::
  Usage:
 ::
 :: 1) Insert the
  following line in your post-commit.bat
  script
 ::
 :: call
  %~dp0\trac-post-commit-hook.cmd %1
  %2
 ::
 :: 2) Check the 'Modify
  paths' section below, be sure to set
  at least TRAC_ENV
 
 
 ::
  ----------------------------------------------------------
 :: Modify paths here:
 
 :: --
  this one must be set
 SET
  TRAC_ENV=C:\trac\MySpecialProject

  
 :: -- set if Python is not in the
  system path
 :: SET
  PYTHON_PATH=
 
 :: -- set to the
  folder containing trac/ if installed
  in a non-standard location 
 :: SET
  TRAC_PATH=
 ::
  ----------------------------------------------------------
 
 :: Do not execute hook if trac
  environment does not exist
 IF NOT
  EXIST %TRAC_ENV% GOTO :EOF
 

  set PATH=%PYTHON_PATH%;%PATH%
 set
  PYTHONPATH=%TRAC_PATH%;%PYTHONPATH%

  
 SET REV=%2
 
 :: GET THE
  AUTHOR AND THE LOG MESSAGE
 for /F
  %%A in ('svnlook author -r %REV% %1')
  do set AUTHOR=%%A
 for /F
  "delims==" %%B in ('svnlook log -r
  %REV% %1') do set LOG=%%B
 
 ::
  CALL THE PYTHON SCRIPT
 Python
  "%~dp0\trac-post-commit-hook" -p
  "%TRAC_ENV%" -r "%REV%" -u "%AUTHOR%"
  -m "%LOG%"

这里最重要的部分是设置TRAC_ENV,它是存储库根目录的路径(SET TRAC_ENV = C:\ trac \ MySpecialProject)

该脚本中的下一个重要事项是执行以下操作:

:: GET THE AUTHOR AND THE LOG
  MESSAGE
   for /F %%A in ('svnlook
  author -r %REV% %1') do set
  AUTHOR=%%A
   for /F "delims==" %%B
  in ('svnlook log -r %REV% %1') do set
  LOG=%%B

如果我们在上面的脚本文件中看到,我正在使用svnlook(这是SVN的命令行实用程序)来获取LOG消息和向存储库提交内容的作者。

然后,脚本的下一行实际上是在调用Python代码来执行票证的关闭并解析日志消息。我必须修改它以传递Log消息和作者(我在Trac中使用的用户名与SVN中的用户名匹配,因此很容易)。

CALL THE PYTHON SCRIPT
 Python
  "%~dp0\trac-post-commit-hook" -p
  "%TRAC_ENV%" -r "%REV%" -u "%AUTHOR%"
  -m "%LOG%"

脚本中的上述行将把Trac环境,修订版,进行提交的人员以及他们的评论传递到python脚本中。

这是我使用的Python脚本。除了常规脚本外,我要做的一件事是,我们使用了一个自定义字段(fixed_in_ver),供我们的质量检查小组使用,它可以确定他们正在验证的修复程序是否在他们正在质量检查中测试的代码版本中。因此,我修改了python脚本中的代码以更新票证上的该字段。我们可以删除不需要的代码,但这是一个很好的示例,说明了如果我们也想这样做,可以在Trac中更新自定义字段。

我这样做是通过让用户选择在他们的评论中包含以下内容:

(version 2.1.2223.0)

然后,我使用python脚本与正则表达式一起使用的相同技术来获取信息。还算不错

无论如何,这是我使用的python脚本,希望这是一个很好的教程,详细说明了我如何使它在Windows世界中正常工作,以便大家都可以在自己的商店中使用它。

如果我们不想处理我的其他代码来更新自定义字段,请从上面的Craig提到的位置(从Edgewall脚本)中获取基本脚本。

# This Subversion post-commit hook script is meant to interface to the

# system.
# 
# It should be called from the 'post-commit' script in Subversion, such as

# REPOS=""
# REV=""
# LOG=`/usr/bin/svnlook log -r $REV $REPOS`
# AUTHOR=`/usr/bin/svnlook author -r $REV $REPOS`

#   closes, fixes

#   references, refs, addresses, re 
#     The specified issue numbers are left in their current status, but

#    Changed blah and foo to do this or that. Fixes #10 and #12, and refs #12.

我要添加"代码猴子的答案是完美的"一件事是要对此保持警惕(我的错误)

:: Modify paths here:

:: -- this one must be set
SET TRAC_ENV=d:\trac\MySpecialProject

:: -- set if Python is not in the system path
:: SET PYTHON_PATH=**d:\python**

:: -- set to the folder containing trac/ if installed in a non-standard location 
:: SET TRAC_PATH=**d:\python\Lib\site-packages\trac**

我没有设置非系统路径,花了我一段时间才能看到明显的:D

只要匹配就可以确定没有其他人犯同样的错误!谢谢代码猴子! 1000000000点:D

回答

首先,非常感谢Code Monkey!

但是,根据trac版本,获取正确的python脚本很重要。要获取适当的版本,SVN签出文件夹:

http://svn.edgewall.com/repos/trac/branches/xxx-stable/contrib

其中xxx对应于我们所使用的trac版本,例如:0.11

否则,我们将收到如下所示的提交后错误:

提交失败(详细信息如下):'/ svn / project / trunk / web / directory /'的合并:200 OK

回答

对于所有想要安装最新版本(0.11.5)的Windows用户:
按照Trac网站TracOnWindows上的说明进行操作。

即使我们拥有64位Windows,也请下载32位1.5 Python。
注意:我在某处看到了有关如何编译Trac以在64位系统上以本机方式工作的说明。

当我们安装所有必需的东西时,转到存储库文件夹。有文件夹挂钩。
在其中放了代码猴子提到的文件,但不要像他那样创建" trac-post-commit-resolve-ticket-ref.py"。接受Quant Analyst的建议,就像他说的那样:

"但是,根据trac版本,获取正确的python脚本很重要。要获取适当的版本,SVN请检查以下文件夹:
http://svn.edgewall.com/repos/trac/branches/xxx-stable/contrib
其中xxx对应于我们使用的追踪版本,例如:0.11"

从那里下载文件" trac-post-commit-hook",并将其放在hooks文件夹中。

在trac-post-commit.cmd中编辑这些行

SET PYTHON_PATH="Path to python installation folder" 
  
  SET TRAC_ENV="Path to folder where you
  did tracd initenv"

记住没有最后一个!

我已经从最后一行-r"%REV%"删除了引号,成为-r%REV%,但是我不知道是否需要这样做。现在这将不起作用(至少在我的Win 2008服务器上),因为钩子将失败(提交将正常)。这与权限有关。默认情况下,权限是受限制的,我们需要允许python或者svn或者trac(无论我不知道如何)更改trac信息。因此,转到trac文件夹,project文件夹,db文件夹,右键单击trac.db并选择属性。转到安全性标签并编辑权限,以允许所有人完全控制。这不是很安全,但是我整天都在此安全问题上浪费了,我不想浪费另一个,只是为了寻找应该为哪个用户启用权限。

希望这可以帮助....
