git - 删除标记但未 merge 的 Git 分支是否安全？

Question

我看过其他关于删除已 merge 的分支如何安全的帖子，但是标记一个分支然后删除该分支是否也安全？

我想分支一个旧版本，进行修复，然后标记它而不将其 merge 回主版本。我不喜欢留下开放的分支，所以我宁愿在它被标记后删除它。

我仍然希望能够单击 SourceTree 中的标签并查看历史记录，就好像它仍在一个分支上一样。

是的，它是安全的。在那里阅读 https://stackoverflow.com/a/2617160/2656799

In Git, branches are just pointers (references) to commits in a directed acyclic graph (DAG) of commits. This means that deleting a branch removes only references to commits, which might make some commits in the DAG unreachable, thus invisible. But all commits that were on a deleted branch would still be in the repository, at least until unreachable commits get pruned (e.g. using git gc).

如果您在删除之前标记分支，它的所有提交仍然可以访问，并且不会被 gc 触及。
