转换git仓库文件编码 [英] Convert git repository file encoding

问题描述

我有一个包含 ISO-8859-1 文件的大型 CVS 存储库，我想将其转换为 git.

I have a large CVS repository containing files in ISO-8859-1 and want to convert this to git.

当然，我可以将 git 配置为使用 ISO-8859-1 进行编码，但我希望将其放在 utf8 中.

Sure I can configure git to use ISO-8859-1 for encoding, but I would like to have it in utf8.

现在使用诸如 iconv 或 recode 之类的工具，我可以转换工作树中文件的编码.我可以用像 converted encoding 这样的消息来提交这个.

Now with tools such as iconv or recode I can convert the encoding for the files in my working tree. I could commit this with a message like converted encoding.

我现在的问题是，是否有可能转换完整的历史记录?从 cvs 转换为 git 时或之后.我的想法是编写一个脚本来读取 git 存储库中的每个提交并将其转换为 utf8 并提交到一个新的 git 存储库中.

My question now is, is there a possibility to convert the complete history? Either when converting from cvs to git or afterwards. My idea would be to write a script that reads each commit in the git repository and to convert it to utf8 and to commit it in a new git repository.

这可能吗(我不确定哈希码以及如何遍历提交、分支和标签).或者有什么工具可以处理这样的事情?

Is this possible (I am unsure about the hash codes and how to walk through the commits, branches and tags). Or is there a tool that can handle something like this?

推荐答案

你可以用 git filter-branch 做到这一点.这个想法是你必须在每次提交中更改文件的编码，并在每次提交时重写.

You can do this with git filter-branch. The idea is that you have to change the encoding of the files in every commit, rewriting each commit as you go.

首先，编写一个脚本来更改存储库中每个文件的编码.它可能看起来像这样:

First, write a script that changes the encoding of every file in the repository. It could look like this:

#!/bin/sh

find . -type f -print | while read f; do
        mv -i "$f" "$f.recode.$$"
        iconv -f iso-8859-1 -t utf-8 < "$f.recode.$$" > "$f"
        rm -f "$f.recode.$$"
done

然后使用 git filter-branch 一遍又一遍地运行这个脚本，每次提交一次:

Then use git filter-branch to run this script over and over again, once per commit:

git filter-branch --tree-filter /tmp/recode-all-files HEAD

其中 /tmp/recode-all-files 是上面的脚本.

where /tmp/recode-all-files is the above script.

存储库刚从 CVS 升级后，您可能在 git 中只有一个分支，其线性历史可以追溯到开始.如果您有多个分支，则可能需要增强 git filter-branch 命令以编辑所有提交.

Right after the repository is freshly upgraded from CVS, you probably have just one branch in git with a linear history back to the beginning. If you have several branches, you may need to enhance the git filter-branch command to edit all the commits.
