背景

鉴于有些人在提交代码的时候并不写注释，而且没有固定格式，所以准备给svn提交时增加强制注释。

按照网上的教程只能识别提交日志为纯数字(123)、纯字母(abc)、数字和字母组合(123abc)，但是不能识别中文，按照下面的配置方法可以正确识别中文，如: 123abc中文 识别出来长度为: 8

环境

centos 7

svn server

方法

  • 进入代码仓库路径下的hooks，cp pre-commit.tmpl pre-commit

  • 修改pre-commit文件如下

#!/bin/sh
# 需要添加下面这行，来正确统计中文个数
export LANG=zh_CN.utf-8
# 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.
#
# 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.
#
#   ***  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.
#
# The default working directory for the invocation is undefined, so
# the program should set one explicitly if it cares.
#                           
# 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 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 runs in an empty environment, unless the server is
# explicitly configured otherwise.  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.
#
# CAUTION:
# For security reasons, you MUST always properly quote arguments when
# you use them, as those arguments could contain whitespace or other
# problematic characters. Additionally, you should delimit the list
# of options with "--" before passing the arguments, so malicious
# clients cannot bootleg unexpected options to the commands your
# script aims to execute.
# For similar reasons, you should also add a trailing @ to URLs which
# are passed to SVN commands accepting URLs with peg revisions.
#
# 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/bin/svnlook
# 提交日志可以为：123、123abc、123abc中文
# 正确识别出来的长度为：3、6、8
# 网上常规配置为：LOGMSG=`$SVNLOOK log -t "$TXN" "$REPOS" | grep "[a-zA-Z0-9]" | wc -c`
# 网上配置不能识别中文，固进行下面的改进
LOGMSG=`$SVNLOOK log -t "$TXN" "$REPOS"`
LOGMSG_LENGTH=`echo ${#LOGMSG}`
# 提交日志长度小于5就不让提交
if [ "$LOGMSG_LENGTH" -lt 5 ];then 
   echo "Failed submission: comments must not be less than 5 characters" 1>&2 
   exit 1
fi
#$SVNLOOK log -t "$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

# All checks passed, so allow the commit.
exit 0
  • 然后 给pre-commit文件添加755权限：
  chmod 755 pre-commit 或 chmod +x pre-commit

如果没有添加权限， 则会报：

Commit blocked by pre-commit hook (exit code 255) with no output 错误。
