SVN的hook机制

关于SVN的hook使用,详细可参看如下文章:

  • https://blog.csdn.net/liumiaocn/article/details/81942161

设定提交时的Comment格式

在Subversion Edge中设定Hook可以在创建的仓库的时候,也可以在创建之后,在仓库列表页面选中相应的仓库,点击info按钮

缺省此模版的信息如下所示

#!/bin/sh

# 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)
#   [3] TXN-NAME     (the name of the transaction that has become REV)
#
# 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.apache.org/repos/asf/subversion/trunk/tools/hook-scripts/ and
# http://svn.apache.org/repos/asf/subversion/trunk/contrib/hook-scripts/


REPOS="$1"
REV="$2"
TXN_NAME="$3"

mailer.py commit "$REPOS" "$REV" /path/to/mailer.conf

我们这里进行如下修改

#!/bin/sh

REPOS="$1"
TXN="$2"

LOG_INFO=`svnlook log -t "$TXN" "$REPOS"`

# check empty comment
if [ _"$LOG_INFO" = _"" ]; then
  echo "" 1>&2
  echo "   ## LOG CHECK : NG: [$LOG_INFO] does not match the rules." 1>&2
  exit 1
fi

# check log format with # :
TICKET_NO=`echo "$LOG_INFO" |sed s/#//g |awk -F : '{print $1}'`
COMMENT_MSG=`echo "$LOG_INFO" |sed s/#//g |awk -F : '{print $2}'`
if [ _"$TICKET_NO" = _"" -o _"$COMMENT_MSG" = _"" ]; then
    echo "" 1>&2
    echo "   ## LOG CHECK : NG: [$LOG_INFO] does not match the rules." 1>&2
    echo "      Sample : # BUG1002: feature F1001 bug fixed" 1>&2
    exit 1
fi

# pre-commit check passed.
exit 0

客户端验证

连续执行两次空comment都成功了

原因是上述的模版只是模版,而没有真正起作用(详细参看文初的链接文章的说明),在Subversion Edge中还提供了rename的功能,实际就是真正将模版起效的过程,选中pre-commit模版,点击rename按钮

客户端验证

再次从客户端提交一个没有comment的变更,可以看到pre-comment的hook机制已经生效。
