从旧的 Git 提交中删除私有信息

发布于 2024-08-20 21:30:43 字数 261 浏览 4 评论 0原文

我有一个使用 Git 进行版本控制的项目,我想将其开源,但其中包含一些特定于其最初使用环境的私人信息。我将更改相关信息以从未包含在存储库中的配置文件加载。我意识到我应该首先这样做,但由于私人信息仍然存在于之前的提交中,我该如何将其从我的历史记录中删除呢?我是否只需要根据最新提交启动一个新存储库并丢失所有历史记录,或者是否有办法在删除任何私人信息记录的同时挽救当前存储库?

编辑:澄清一下,我不想完全删除包含此私人信息的文件,因为它们仍在使用。相反,我想删除/删除/更改其中某些字符串的出现。

I have a project versioned with Git that I'd like to make open source, but it has some private information in it that is specific to the environment in which it was originally used. I'm going to change the information in question to load from a config file which is not included in the repository. I realize I should have done this in the first place, but since the private information still exists in previous commits, how can I go about removing it from my history? Do I just have to start a new repository based on the latest commit and lose all my history or is there a way to salvage the current repository while removing any record of the private information?

Edit: To clarify, I don't want to completely remove the files that contain this private information, because they are still used. Rather, I want to remove/blank out/change the occurrence of certain strings within them.

我建议使用 BFG Repo-Cleaner,这是一个更简单、更快的替代方案git-filter-branch 专门设计用于从 Git 存储库中删除私有数据。

使用说明提供了更详细的步骤,但核心位是只需:下载 BFG 的 jar (需要 Java 8 或更高版本)并运行此命令:

$ java -jar bfg.jar  --replace-text replacements.txt  my-repo.git

replacements.txt 文件应包含您想要执行的所有替换,格式如下(每行一个条目 - 请注意不应包含注释):

PASSWORD1 # Replace literal string 'PASSWORD1' with '***REMOVED***' (default)
PASSWORD2==>examplePass         # replace with 'examplePass' instead
PASSWORD3==>                    # replace with the empty string
regex:password=\w+==>password=  # Replace, using a regex

您的整个存储库历史记录将被扫描,并且所有非二进制文件(大小低于 1MB)将执行替换:任何匹配的字符串(不在您的最新提交中)都将被替换。

全面披露:我是 BFG Repo-Cleaner 的作者。

I'd recommend using the BFG Repo-Cleaner, a simpler, faster alternative to git-filter-branch specifically designed for removing private data from Git repos.

The usage instructions give the steps in more detail, but the core bit is just: download the BFG's jar (needs Java 8 or above) and run this command:

$ java -jar bfg.jar  --replace-text replacements.txt  my-repo.git

The replacements.txt file should contain all the substitutions you want to do, in a format like this (one entry per line - note the comments shouldn't be included):

PASSWORD1 # Replace literal string 'PASSWORD1' with '***REMOVED***' (default)
PASSWORD2==>examplePass         # replace with 'examplePass' instead
PASSWORD3==>                    # replace with the empty string
regex:password=\w+==>password=  # Replace, using a regex

Your entire repository history will be scanned, and all non-binary files (under 1MB in size) will have the substitutions performed: any matching string (that isn't in your latest commit) will be replaced.

Full disclosure: I'm the author of the BFG Repo-Cleaner.

我不久前为此写了一个脚本。您可以在这里找到它: https://gist.github.com/dound/76ea685c05c4a7895247457eb676fe69

(原始文章可从 archive.org 查看: https://web.archive.org/web/20160208235904/http://dound.com:80/2009/04/git-forever-remove-files -or-folders-from-history/)

该脚本构建在 git 上git 自带的 -filter-branch 工具。如果您好奇,可以在此处阅读有关从 git 存储库中删除文件的更多信息,但是使用上面链接中的脚本应该很容易,并且您真正需要完成删除该私人信息。

I wrote a script for this a little while ago. You can find it here: https://gist.github.com/dound/76ea685c05c4a7895247457eb676fe69

The script builds on the git-filter-branch tool which comes with git. If you're curious, you can read more about removing files from a git repo here, but using the script from the link above should be easy and all you really need to accomplish removing that private information.
