Git svn relies heavily on the svn URL. Every commit that is imported from svn has a <code>git-svn-id</code> that includes the svn URL.

A valid relocations strategy is to call <code>git-svn clone</code> on the new repository and merge the changes onto that new close. For a more detailed procedure, see this article:

<h2><code>git filter-branch</code></h2>

<a href="https://gist.github.com/krlmlr/6307013" rel="nofollow">This script</a>, taken from <a href="http://therightstuff.de/2009/06/25/Rewriting-Git-History-Relocating-Subversion-URLs.aspx" rel="nofollow">a blog entry</a>, has worked for me. Supply old and new repo URL as parameter, just like for <code>svn switch --relocate</code>.

The script calls <code>git filter-branch</code> to replace Subversion URLs in the <code>git-svn-id</code> in the commit messages, updates <code>.git/config</code>, and also updates <code>git-svn</code> metadata by recreating it using <code>git svn rebase</code>. While <code>git svn clone</code> might be the more robust solution, the <code>filter-branch</code> approach works much faster for huge repositories (hours vs. days).

<pre class="lang-bash prettyprint-override"><code>#!/bin/sh

# Must be called with two command-line args.
# Example: git-svn-relocate.sh http://old.server https://new.server
if [ $# -ne 2 ]
then
 echo "Please invoke this script with two command-line arguments (old and new SVN URLs)."
 exit $E_NO_ARGS
fi

# Prepare URLs for regex search and replace.
oldUrl=`echo $1 | awk '{gsub("[\\\.]", "\\\\\\\&amp;");print}'`
newUrl=`echo $2 | awk '{gsub("[\\\&amp;]", "\\\\\\\&amp;");print}'`

filter="sed \"s|^git-svn-id: $oldUrl|git-svn-id: $newUrl|g\""
git filter-branch --msg-filter "$filter" -- --all

sed -i.backup -e "s|$oldUrl|$newUrl|g" .git/config

rm -rf .git/svn
git svn rebase
</code></pre>

An svn repository I'm mirroring through git-svn has changed URL.

In vanilla svn you'd just do <code>svn switch --relocate old_url_base new_url_base</code>.

How can I do this using git-svn? 

Simply changing the svn url in the config file fails.

git-svn: what's the equivalent to `svn switch --relocate`?

我通过git-svn镜像的一个svn存储库已经更改了URL。在vanilla svn中，您只需执行svn switch --relocate old_url_base new_url_base。如何使用git-svn完成此操作？简单地更改配置文件中的svn url将失败。
