如何防止用户将二进制文件提交到subversion中？

Question

我有一个顽固的用户,他固执地坚持将他的二进制文件(可执行文件,DLL)提交到我们的subversion存储库中.我会进去删除它们,但当然没有任何东西可以从subversion中删除.

虽然有时我们需要提交二进制文件,但我不希望用户这样做是例行公事.我可以设置一个ignore属性,但如果真的确定它们,则不会阻止用户提交二进制文件.我想做的是能够在逐个目录的基础上控制提交指定文件类型的能力,特别是.exe和.dll文件.

在SVN中有没有办法做到这一点？如果它有任何不同,我们使用VisualSVN服务器和TortoiseSVN.

这是一个小钩子脚本,它正在做你想要的:你必须配置两件事:

• illegal_suffixes:一个包含所有后缀的python列表,应该中止提交
• cmdSVNLOOK:svnlook程序的路径

import sys
import subprocess 
import re

#this is a list of illegal suffixes:
illegal_suffixes = ['.exe','.dll']

# Path to svnlook command:
cmdSVNLOOK="/usr/bin/svnlook";

def isIllegalSuffix(progname):
    for suffix in illegal_suffixes:
        if (ptFilename.endswith(suffix)):
            return True
    return False

######### main program ################
repopath = sys.argv[1]
transact = sys.argv[2]

retVal = 0
svninfo = subprocess.Popen([cmdSVNLOOK, 'changed', '-t', transact, repopath], 
                                                        stdout = subprocess.PIPE, stderr=subprocess.PIPE)
(stdout, stderr) = svninfo.communicate();

prog = re.compile('(^[ACUDRM_])[ACUDRM]*\s+(.+)')  # regex for svnlook output
for line in stdout.split("\n"):
    if (line.strip()!=""):
        match=re.search(prog, line.strip())
        if match:
            mode = match.group(1) 
            ptFilename = match.group(2)
            if mode == 'A' and isIllegalSuffix(ptFilename): 
              retVal = 1
              sys.stderr.write("Please do not add the following ")
              sys.stderr.write("filetypes to repository:\n")
              sys.stderr.write(str(illegal_suffixes)+"\n")
              break
        else:
            sys.stderr.write("svnlook output parsing failed!\n")
            retVal = 1
            break
    else:
        # an empty line is fine!
        retVal = 0
sys.exit(retVal)

蒂姆:

你可以尝试这个python钩子脚本.它(松散地)基于上面的那个,但允许拒绝路径的正则表达式模式,并允许通过开始一行来覆盖检查

此改变:

在日志消息中.它使用新的python打印语法,因此它需要一个相当新版本的python(2.6+？).
