git - 为什么本地git显示的分支比服务器多

Question

Azure DevOps Server(2019，本地安装)中的分支列表正确显示所有部分中仅三个分支，因为所有其他分支已被 merge 和删除:

为什么git branch -r返回大量旧的 merge 或删除的分支(通过 UI)？如何修复存储库以仅包含 Azure DevOps Server Web 界面中显示的分支？

Answer 1

当在源上删除分支时，跟踪该分支的本地分支不会被删除。这是一个明确的操作，因为那里可能还有您尚未推送的工作。要清理跟踪源上不再存在的分支的本地分支，您需要修剪远程分支。

git remote prune命令删除本地远程跟踪分支，该分支不再存在于远程上。

Prune
Deletes stale references associated with <name>. By default, stale remote-tracking branches under <name> are deleted, but depending on global configuration and the configuration of the remote we might even prune local tags that haven’t been pushed there. Equivalent to git fetch --prune <name>, except that no new references will be fetched.

如果您想查看运行 prune 命令将删除的分支而不实际删除它们，请添加 --dry-run选项。

示例:git remote prune origin --dry-run

如torek commented :

You can also use git fetch --prune (abbreviated git fetch -p) or set fetch.prune to true.
The last one means you never have to run git remote prune or git fetch -p, at the cost of not being able to restore an accidentally-deleted server branch.
