如何让git将tar档案作为目录透明处理？ [英] How to have git treat tar archives transparently as directories?

问题描述

我希望 git to a version a tar 文件，以便对于与存储库相关的功能，例如 git-diff 的问题（甚至复杂 git-merge 冲突解决方案）的问题文件似乎是一个目录，其中包含的文件定期提交给git，除了在签出时，应该再次获得有效的 tar 存档。这是不是可以实现？

我首先想到了使用涂抹/清洁过滤器，但它们只允许您修改存储的git blob的文件内容。

所以，现在我正考虑使用 hooks （ pre-commit 和结账后，建议此处，但我希望还有一个 pre-add 过滤器......），它将简单地在 tar 文件和目录结构之间进行转换或者，为了正确保持元数据，直接使用 git objects （或者，作为折衷方案，使用中间目录但覆盖元数据一个）。但是，在我开始这个潜在的疯狂工作之前，有没有一种更好的方法来达到这个目的，或者
$ b

• $ b 已存在的解决方案？

  这与<一个href =https://stackoverflow.com/q/8001663/321973> git可以将zip文件作为目录和zip文件中的文件视为blob？，尽管我希望由于 tar 文件仅仅是文件和元数据的串联而没有压缩，更容易。

  解决方案

  我会建议在其中一个评论中提到什么，即使用 textconv 。

  
  
  

  使用 cat 可以简单地调用 - textconv 选项用于 git diff 。

  
  
  

  可以使用 renormalize 选项o你可以使用 merge.renormalize 。

  
  
  

  将其设置为默认值。我从来没有真正测试过这个，但我相信它将工作。

  
  

  I'd like git to version a tar file such that for repository-related functions such as git-diff (and even sophisticated git-merge conflict solutions) the file appears to be a directory with its included files being committed regularly to git, except that on checkout one should obtain a valid tar archive again. Is this somehow achievable?

  I first thought about using smudge/clean filters, but they merely allow you to modify the file contents of the stored git blob.

  So, now I'm thinking about using hooks (pre-commit and post-checkout, as suggested here, though I wish there were a pre-add filter as well...) which would either simply convert between tar file and directory structure or, in order to maintain the metadata correctly, directly plumbing with git objects (or, as a compromise, use the intermediate directory but override the metadata). But, before I start with this potentially insane work, is there either

  • a better way to achieve this, or
  • an already existing solution?

  This is strongly related to Can git treat zip files as directories and files inside the zip as blobs?, although I hope that due to tar files being merely a concatenation of files and metadata without compression, treating them might be easier.

  解决方案

  I would suggest what was mentioned in one of the comments, namely to use textconv.

  Instead of manually, using cat, you could simple invoke the --textconv option for git diff.

  For merging you can use the renormalize option, or configure this as the default with merge.renormalize.

  I have never actually tested this, but I believe it will work.
