代碼嗅探器SVN提交前鉤子

Question

我一直在試圖讓代碼嗅探器充當svn pre-commit hook，遵循pear的指導。但是，雖然我100％肯定我的代碼應該是無效的，我得到沒有錯誤和項目提交沒有問題。

除了遵循梨給出的指導，還有什麼需要做的嗎？

而且從顛覆我的預提交的文件：

#!/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. 
commit-access-control.pl "$REPOS" "$TXN" commit-access-control.cfg || exit 1 

C:\wamp\bin\php\php5.4.3\scripts\phpcs-svn-pre-commit "$REPOS" -t "$TXN" >&2 || exit 1 

# All checks passed, so allow the commit. 
exit 0 

我是很新的這兩個SVN和codesniffer，所以我幾乎只是遵循指南和運行測試，因爲我走了。在得到這個工作的任何意見或建議可以理解的:)

UPDATE

我設法得到了一些成果了我SVN掛鉤的，現在卻顯示了基於腳本錯誤的列表。我不熟悉SVN所需的腳本語言，所以我不知道如何解決這些問題。錯誤的

列表：

REPOS不被識別爲內部或外部命令

TXN不被識別爲內部或外部命令

未知命令 '的/ usr/local/bin中/ svnlook的'

$ svnlook的不被識別爲內部或外部命令

Answer 1

從您的可執行文件的路徑來看（ C:\wamp\bin\php\php5.4.3\php.exe），我假設你正在使用Windows機器。

您問題中的pre-commit文件看起來像Linux Bash Shell腳本。 Bash與您在Windows下使用的批處理文件有不同的語法。

我建議你使用爲Windows機器製作的pre-commit.tmpl文件。 您可能在hooks文件夾中有這些文件。 我使用的是Linux，所以很遺憾，我不能幫助您進一步此搜索上...

的pre-commit鉤看起來像這樣（從An Introduction to Subversion Hook Scripts on Windows採取摘錄）：

@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
