混帐prepush挂钩：获取分支推到

Question

我怎样才能像已经被推到在预推挂钩的背景下，新的分支？我知道如何获得当前分支，但它可能与推送到的一个/多个分支不同。

我以为解析命令，但我担心我可能会忘记某些情况下。像git push，git push origin master都将推动掌握等

Answer 1

while read oldrev newrev refname 
do 
    if [[ "$newrev" != "0000000000000000000000000000000000000000" ]] ; then 
      branch=${refname#refs/heads/} 
    fi 
done 

Answer 2

这里有一个可能的循环，但要与远程分支或标记名称做什么目前尚不清楚对我来说，和/或本地REF：

#! /bin/sh 

NULLSHA=0000000000000000000000000000000000000000 # 40 0's 

say() { 
    echo "$@" 1>&2 
} 

while read localref localhash foreignref foreignhash; do 
    case $foreignref in 
    refs/heads/*) 
     reftype=branch 
     shortref=${foreignref#refs/heads/};; 
    refs/tags/*) 
     reftype=tag 
     shortref=${foreignref#refs/tags/};; 
    *) reftype=unknown-ref-type 
     shortref=$foreignref;; 
    esac 
    say "pushing to $reftype $shortref" 
    case $localhash,$foreignhash in 
    $NULLSHA,*) say "(push with intent to delete)";; 
    *,$NULLSHA) say "(push with intent to create)";; 
    *) say "(push with intent to update from $foreignhash to $localhash)" 
     # for branch updates only, let's see if it's a fast-forward 
     if [ $reftype = branch ]; then 
      if git merge-base --is-ancestor $foreignhash $localhash; then 
       say "(this is a fast-forward)" 
      else 
       say "(this can only work if forced)" 
      fi 
     fi;; 
    esac 
done 

（注：这是不是很好的测试）。
