git-svn具有严格的权限 [英] git-svn with strict permission

问题描述

我正在开发一个不受我控制的svn存储库。它使用一个标准的布局，拥有非常严格的权限。

我没有读取父文件夹的权限。

  svn：//foo.bar/project/ 
 svn：//foo.bar/project/branches 
  

但是我可以阅读 svn：//foo.bar/project/trunk 和 svn ：//foo.bar/project/branches/x 。

如果我用git-svn使用多个遥控器，我可以提取并提交这些分支。但是git-svn不会找到分支的父项。多个遥控器将被视为不同的存储库。

看来我可以修改git-svn来纠正后面的父源。但我不知道Perl。
是否可以编写脚本修复分支的父散列。或者我可以使用一个简单的脚本创建新的远程分支，然后让git-svn来获取它。 我写了一个简单的肮脏的shell脚本来初始化新的分支。它将为svn分支创建第一个提交。之后， git-svn fetch --all 就可以工作了。

 <！c $ c>＃！/ bin / bash 
 
 branch = $ 1 
 prefix = svn-remote.svn- $ branch 
 rooturl = svn：//示例。 com 
 branchurl = $ rooturl / foo / branches 
 git config $ prefix.ignore -path^ exclude
 git config $ prefix.url $ branchurl / $ branch 
 git config $ prefix.fetch：refs / remotes / $ branch 
 $ b $ logentry = $（svn log -v -r0：HEAD  - 停止复制-l 1 --xml $ branchurl / $ branch） 
 torev = $（echo$ logentry| grep revision | grep -o [0-9] *）
 fromrev = $（echo$ logentry| grep copyfrom-rev | grep -o [ 0-9] *）
 frompath = $（echo$ logentry| grep copyfrom-path | sed -E's / \s * copyfrom-path =（。*）/ \ 1 / '）
 author = $（echo$ logentry| grep< author>| sed -E's＃< /？author> ## g'）
 author_date = $（echo $ logentry| grep< date>| sed -E's＃< /？date> ## g'）
 
 if [-z $ torev]; then 
出口1; 
 fi 
 
 if [-z $ fromrev];然后
 exit 2; 
 fi 
 
 if [-z $ frompath];然后
 exit 3; 
 fi 
 
 fromurl = $ rooturl $ frompath @ $ fromrev 
 tourl = $ branchurl / $ branch @ $ torev 
 frombranch = $（basename $ frompath）
 echo $ fromurl 
 echo $ tourl 
 echo $ fromrev 
 parent = $（git svn log -r $ fromrev $ frombranch --oneline --show-commit | grep $ fromrev | awk '{print $ 3}'）
 if [-z $ parent];然后
 exit 4; 
 fi 
 uuid = $（git log -1 | grep git-svn-id：| awk'{print $ NF}'）
 tree = $（git cat-file commit $ parent | head -1 | cut -d''-f 2）
 echo tree $ tree 
 echo父母
 echo uuid $ uuid 
 
 head = $（ GIT_AUTHOR_NAME = $ author GIT_AUTHOR_EMAIL = $ author @ $ uuid GIT_AUTHOR_DATE = $ author_date git commit-tree $ tree -p $ parent<< EOF 
 $ logentry 
 
 git-svn-id： $ tourl $ uuid 
 EOF 
）
 echo $ head 
 git update-ref refs / remotes / $ branch $ head 
  

I am working on a svn repository out of my control. It uses a standard layout with very strict permissions.

I have't read permission to the parent folder.

svn://foo.bar/project/
svn://foo.bar/project/branches

But I can read svn://foo.bar/project/trunk and svn://foo.bar/project/branches/x.

If I use multiple remotes with git-svn, I can fetch and commit these branches. But the git-svn will not find the branch's parent. Multiple remotes will be treated as different repositories.

It seems I can modify the git-svn to correct the follow parent source. But I don't known perl. Is it possible to write a script fix the branch's parent hash. Or can I use a simple script to create new remote branch then let git-svn to fetch it.

解决方案

I wrote a simple dirty shell script to init the new branch.It will create the first commit for the svn branch. After that the git-svn fetch --all will work.

#!/bin/bash

branch=$1
prefix=svn-remote.svn-$branch
rooturl=svn://example.com
branchurl=$rooturl/foo/branches
git config $prefix.ignore-paths "^exclude"
git config $prefix.url $branchurl/$branch
git config $prefix.fetch :refs/remotes/$branch

logentry=$(svn log -v -r0:HEAD --stop-on-copy -l 1 --xml $branchurl/$branch)
torev=$(echo "$logentry" |grep revision |grep -o [0-9]*)
fromrev=$(echo "$logentry" |grep copyfrom-rev |grep -o [0-9]*)
frompath=$(echo "$logentry" |grep copyfrom-path | sed -E 's/\s*copyfrom-path="(.*)"/\1/')
author=$(echo "$logentry" |grep "<author>" |sed -E 's#</?author>##g')
author_date=$(echo "$logentry" |grep "<date>" |sed -E 's#</?date>##g')

if [ -z $torev ];then
    exit 1;
fi

if [ -z $fromrev ];then
    exit 2;
fi

if [ -z $frompath ];then
    exit 3;
fi

fromurl=$rooturl$frompath@$fromrev
tourl=$branchurl/$branch@$torev
frombranch=$(basename $frompath )
echo $fromurl
echo $tourl
echo $fromrev
parent=$(git svn log -r $fromrev $frombranch --oneline --show-commit |grep $fromrev |awk '{print $3}')
if [ -z $parent ];then
    exit 4;
fi
uuid=$(git log -1 |grep git-svn-id: | awk '{print $NF}')
tree=$(git cat-file commit $parent |head -1 |cut  -d ' ' -f 2)
echo tree $tree
echo parent $parent
echo uuid $uuid

head=$(GIT_AUTHOR_NAME=$author GIT_AUTHOR_EMAIL=$author@$uuid GIT_AUTHOR_DATE=$author_date git commit-tree $tree -p $parent <<EOF
$logentry

git-svn-id: $tourl $uuid 
EOF
)
echo $head
git update-ref refs/remotes/$branch $head
