代码嗅探器SVN预提交钩子

时间:2012-08-15 09:14:37

标签: php svn pear pre-commit-hook codesniffer

我一直在努力让代码嗅探器充当svn pre-commit钩子,遵循pear的指南。但是,虽然我100%肯定我的代码应该无效但我没有错误,项目提交没有问题。

除了遵循梨给出的指南之外,还有什么需要做的吗?

来自subversion的预提交文件:

#!/bin/sh

# PRE-COMMIT HOOK
#
# The pre-commit hook is invoked before a Subversion txn is
# committed.  Subversion runs this hook by invoking a program
# (script, executable, binary, etc.) named 'pre-commit' (for which
# this file is a template), with the following ordered arguments:
#
#   [1] REPOS-PATH   (the path to this repository)
#   [2] TXN-NAME     (the name of the txn about to be committed)
#
#   [STDIN] LOCK-TOKENS ** the lock tokens are passed via STDIN.
#
#   If STDIN contains the line "LOCK-TOKENS:\n" (the "\n" denotes a
#   single newline), the lines following it are the lock tokens for
#   this commit.  The end of the list is marked by a line containing
#   only a newline character.
#
#   Each lock token line consists of a URI-escaped path, followed
#   by the separator character '|', followed by the lock token string,
#   followed by a newline.
#
# The default working directory for the invocation is undefined, so
# the program should set one explicitly if it cares.
#
# 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/local/bin/svnlook
$SVNLOOK log -t "$TXN" "$REPOS" | \
   grep "[a-zA-Z0-9]" > /dev/null || exit 1

# Check that the author of this commit has the rights to perform
# the commit on the files and directories being modified.

我对SVN和codesniffer都很陌生,所以我非常关注指南和运行测试。任何有关使其工作的建议或提示将不胜感激:)

更新

我已经设法从我的svn钩子中获得了一些结果,但它现在显示了基于脚本的错误列表。我不熟悉SVN所需的脚本语言,所以我不知道如何解决这些问题。

错误列表:

REPOS不被识别为内部或外部命令

TXN未被识别为内部或外部命令

未知命令'/ usr / local / bin / svnlook'

$ SVNLOOK未被识别为内部或外部命令

1 个答案:

答案 0 :(得分:1)

从您的可执行文件路径(C:\wamp\bin\php\php5.4.3\php.exe)判断,我假设您正在使用Windows计算机。

您问题中的pre-commit文件看起来像Linux Bash Shell脚本。 Bash与您在Windows下使用的批处理文件具有不同的语法。

我建议你使用为Windows机器制作的pre-commit.tmpl文件。 你可能在hooks文件夹中找到了这些内容。 我使用Linux机器,所以不幸的是我无法帮助你进一步搜索...

pre-commit挂钩将如下所示(摘录自An Introduction to Subversion Hook Scripts on Windows):

@echo off
:: Stops commits that don't include a log message of at least 6 characters.
@echo off

setlocal

rem Subversion sends through the repository path and transaction id
set REPOS=%1
set TXN=%2

svnlook log %REPOS% -t %TXN% | findstr ...... > nul
if %errorlevel% gtr 0 (goto err) else exit 0

:err
echo --------------------------------------------------------------------------- 1>&2
echo Your commit has been blocked because it didn't include a log message. 1>&2
echo Do the commit again, this time with a log message that describes your changes. 1>&2
echo --------------------------------------------------------------------------- 1>&2
exit 1
