题

我在带有 Trac / SVN 的 Windows 环境中运行，我希望提交到存储库以集成到 Trac 并关闭 SVN 注释中指出的错误。

我知道有一些提交后挂钩可以做到这一点，但关于如何在 Windows 上执行此操作的信息不多。

有谁做过成功的吗？为了实现这一目标，您采取了哪些步骤？

这是我需要在 SVN 中放置的钩子，但我不太确定如何在 Windows 环境中执行此操作。

Trac 提交后挂钩

有帮助吗？

解决方案 2

好吧，现在我有时间在弄清楚这一切后发布我的经验，并感谢克雷格让我走上正确的轨道。以下是您需要执行的操作（至少对于 SVN v1.4 和 Trac v0.10.3）：

  1. 找到您想要启用提交后挂钩的 SVN 存储库。
  2. 在 SVN 存储库内有一个名为 hooks 的目录，您将在其中放置提交后挂钩。
  3. 创建一个文件 post-commit.bat （这是 SVN 提交后自动调用的批处理文件）。
  4. 将以下代码放入 post-commit.bat 文件中（这将调用您的提交后 cmd 文件，并传入 SVN 自动传递的参数，%1 是存储库，%2 是已提交的修订版。

%~dp0 rac-post-commit-hook.cmd %1 %2

  1. 现在创建 trac-post-commit-hook.cmd 文件，如下所示：

@回声关闭
::
::Windows的TRAC邮递脚本
::
::由马库斯（Markus）贡献，由CBoos修改。

::用法：
::
::1）在您的commit.bat脚本中插入以下行
::
::致电％〜DP0 TRAC-POST-COMMIT-HOK.CMD％1％2
::
::2）检查下面的“修改路径”部分，请确保至少设置TRAC_ENV


:: ----------------------------------------------------------
::此处修改路径：

::- 这个 必须 被设置
设置trac_env = c： trac myspecialproject

::- 设置如果Python不在系统路径中
::设置python_path =

::- 设置为包含TRAC/的文件夹/如果安装在非标准位置
::设置trac_path =
:: ----------------------------------------------------------

::如果不存在TRAC环境，请勿执行挂钩
如果不存在％trac_env％goto：eof

设置路径=%PYTHON_PATH%;%PATH%
设置pythonpath =％trac_path％;％pythonpath％

设置转速=%2

::获取作者和日志消息
for /f %% a in（'svnlook作者-r％rev％1'）do seet witer = %% a
for /f“ delims ==” %% b in（'svnlook log -r％rev％1'）确实设置log = %% b

::调用 Python 脚本
Python“％〜DP0 TRAC -POST -COMMIT -HOK” -P“％TRAC_ENV％” -R“％Rev％” -U“ -U”％fureter％“ -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: rac\MySpecialProject)

此脚本中的下一个非常重要的事情是执行以下操作：

::获取作者和日志消息
for /f %% a in（'svnlook作者-r％rev％1'）do seet witer = %% a
for /f“ delims ==” %% b in（'svnlook log -r％rev％1'）确实设置log = %% b

如果您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 消息以及提交到存储库的作者。

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

调用 Python 脚本
Python“％〜DP0 TRAC -POST -COMMIT -HOK” -P“％TRAC_ENV％” -R“％Rev％” -U“ -U”％fureter％“ -m”％log％“”

脚本中的上述行将把 Trac 环境、修订版本、提交者及其评论传递到 python 脚本中。

这是我使用的 Python 脚本。除了常规脚本之外，我做的一件事是我们使用自定义字段 (fixed_in_ver)，我们的 QA 团队使用该字段来判断他们正在验证的修复是否位于他们在 QA 中测试的代码版本中。因此，我修改了 python 脚本中的代码来更新票证上的该字段。您可以删除该代码，因为您不需要它，但它是一个很好的示例，说明您可以在 Trac 中更新自定义字段（如果您也想这样做）。

我通过让用户选择在他们的评论中包含类似以下内容来做到这一点：

（版本2.1.2223.0）

然后，我使用 Python 脚本与正则表达式相同的技术来获取信息。还不错。

无论如何，这是我使用的 python 脚本，希望这是一个很好的教程，讲述了我如何让它在 Windows 世界中工作，这样你们都可以在自己的商店中利用它......

如果您不想处理我用于更新自定义字段的附加代码，请从此位置获取基本脚本，如上面 Craig 提到的（来自 Edgewall 的脚本)

# This Subversion post-commit hook script is meant to interface to the
# Trac (http://www.edgewall.com/products/trac/) issue tracking/wiki/etc 
# system.
# 
# It should be called from the 'post-commit' script in Subversion, such as
# via:
#
# REPOS="$1"
# REV="$2"
# LOG=`/usr/bin/svnlook log -r $REV $REPOS`
# AUTHOR=`/usr/bin/svnlook author -r $REV $REPOS`
# TRAC_ENV='/somewhere/trac/project/'

#  -r "$REV"       \
#  -u "$AUTHOR"    \
#  -m "$LOG"       \
#  -s "$TRAC_URL"
#
# It searches commit messages for text in the form of:
#   command #1
#   command #1, #2
#   command #1 & #2 
#   command #1 and #2
#
# You can have more then one command in a message. The following commands
# are supported. There is more then one spelling for each command, to make
# this as user-friendly as possible.
#
#   closes, fixes
#     The specified issue numbers are closed with the contents of this
#     commit message being added to it. 
#   references, refs, addresses, re 
#     The specified issue numbers are left in their current status, but 
#     the contents of this commit message are added to their notes. 
#
# A fairly complicated example of what you can do is with a commit message
# of:
#
#    Changed blah and foo to do this or that. Fixes #10 and #12, and refs #12.
#
# This will close #10 and #12, and add a note to #12.

其他提示

本杰明的答案很接近，但在 Windows 上，您需要为挂钩脚本文件提供可执行扩展名，例如 .bat 或 .cmd。我使用.cmd。您可以采用模板脚本（unix shell 脚本、shell 脚本）并将它们转换为 .bat/.cmd 语法。

但要回答与 Trac 集成的问题，请按照以下步骤操作。

  1. 确保 Python.exe 位于系统路径上。这将使您的生活更轻松。

  2. 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挂钩脚本。

    @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

  3. 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

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

提交后挂钩位于服务器端存储库所在的“hooks”目录中。我不知道你的环境中哪里有它们，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

我要添加的一件事是“Code Monkey 的答案是完美的” - 对此要保持警惕（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，花了我一段时间才看到明显的：D

只要匹配，确保没有其他人犯同样的错误！感谢代码猴子！1000000000 点 :D

首先非常感谢Code Monkey！

但是，根据您的 trac 版本获取正确的 python 脚本非常重要。要获取适当的版本，SVN 检查文件夹：

http://svn.edgewall.com/repos/trac/branches/xxx-稳定/贡献

在哪里 xxx 对应于您正在使用的 trac 版本，例如：0.11

否则，您将收到如下所示的提交后错误：

提交失败（详细信息如下）：合并“/svn/project/trunk/web/directory/”：200 好

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

即使您有 64 位 Windows，也请下载 32 位 1.5 Python。笔记：我在某处看到了如何编译 trac 以在 64 位系统上本地工作的说明。

当您安装所需的所有内容时，请转到存储库文件夹。有文件夹挂钩。里面放了 Code Monkey 提到的文件，但不要像他那样创建“trac-post-commit-resolve-ticket-ref.py”。听取量化分析师的建议并按照他说的去做：

“但是，根据您的 trac 版本获取正确的 python 脚本非常重要。要获取适当的版本，SVN 检查文件夹：http://svn.edgewall.com/repos/trac/branches/xxx stable/conter xxx对应于您正在使用的TRAC版本，例如：0.11"

从那里下载文件“trac-post-commit-hook”并将其放入 hooks 文件夹中。

在 trac-post-commit.cmd 中编辑这些行

SET PYTHON_PATH="python 安装文件夹的路径"

设置TRAC_ENV =“通往文件夹的路径，您在哪里进行tracD启动”

切记不要最后\！！！

我已将最后一行 -r "%REV%" 中的引号删除为 -r %REV% 但我不知道是否需要这样做。这现在不起作用（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，权限受到限制，我们需要允许 python 或 svn 或 trac （无论我不知道什么）更改 trac 信息。因此，转到 trac 文件夹、项目文件夹、db 文件夹，右键单击 trac.db 并选择属性。转到安全选项卡并编辑权限以允许每个人完全控制。这不是那么安全，但我在这个安全问题上浪费了一整天，我不想浪费另一天只是为了找到应该为哪个用户启用权限。

希望这可以帮助....
