将Git注释添加到blob [英] Adding Git notes to a blob

问题描述

使用案例：应该可以向git构件添加元数据（如属性）。

p>

我们计划为每个组件提供一个git repo，因此为每个提交对象应用一个便笺可以实现这个要求。

<现在，我们还需要一个组件内的文件的元数据（在这种情况下为git repo）。为此，我尝试将注释附加到作为提交一部分的Blob。

它接受笔记，甚至可以将笔记推送到中央仓库。

这是一个安全可靠的git使用情况吗？

解决方案

是的，您可以这样使用 git笔记。

博客文章 Alex Blewitt 的Git Tip of the Week：Git Notes 提醒我们一些 git notes 优点和难点：



笔记不必是文本的，也不是他们必须是可合并的东西。

他们甚至不需要在 notes / commits ref;您可以根据任何参考创建笔记。

实际上， Gerrit 作品（我之前写过）。

Gerrit将其评论信息存储在Git存储库中的notes / review下。通常情况下，这不会显示出来（git日志只在笔记/提交refspace中显示注释）

• Git Notes （存储在 .git / refs / notes ）



• 合并：由于笔记文件基本上位于其自己的分支上，所以内容不会与分支之间的合并合并。如果你想合并git笔记，那么在单独的行中按照 Key：Value 来实现git笔记合并必杀技。

注意到自我文章也指出推/拉笔记是如何不容易。

除了这两个问题（合并和推动）之外，你应该与你的' git notes '用例保持一致。

I am trying to realize a use-case using git.

Use Case : It should be possible to add metadata (like Attributes) to git artifacts.

We plan to have a git repo for each component, so applying a note for each commit object could realize this requirement.

Now, it is also required that we have metadata for files within a component (git repo in this case). For this i tried to attach a note to a blob which was part of a commit.

It accepts the note and even I am able to push the notes to central repo.

Is this a safe and reliable usage of git notes for this use-case?

解决方案

Yes, you can use git notes that way.

The blog post "Git Tip of the Week: Git Notes" from Alex Blewitt reminds us about some of the git notes advantages and gotcha:

the notes don’t have to be textual, nor do they have to be something which is mergeable.
They don’t even need to be on the notes/commits ref; you can create notes based on any reference.

In fact, this is how Gerrit works (which I’ve written about before).
Gerrit stores its review information in the Git repository under notes/review. Ordinarily, this doesn’t show up (the git log only shows notes in the notes/commits refspace)

• Git Notes are, in effect, a separate ‘branch’ of the repository (stored at .git/refs/notes)

• merges: since the notes file is essentially on its own branch, the content doesn’t get merged with merges between branches. If you wanted to merge git notes, then following the Key: Value on separate lines is the way to achieve git note merging nirvana.

The "note to self" article also points out how pushing/pulling notes isn't exactly easy.

Beside those two issues (merging and pushing), you should be ok with your 'git notes' use case.
