为什么 git 一直告诉我它是“在后台自动打包存储库以获得最佳性能”？

Why does git keep telling me it's "Auto packing the repository in background for optimum performance"?
提问by Andrew Ferrier
Note: I don'tthink this is a duplicate of this question, which is talking about a non-background pack which hangsgit with a subtly different error message.
注意：我不认为这是这个问题的重复，它是在谈论一个非背景包，它挂起git并带有一个微妙不同的错误消息。
In one of my git repositories, each time I invoke (for example) git fetch, git prints:
在我的一个 git 存储库中，每次我调用 (例如) 时git fetch，git 都会打印：
Auto packing the repository in background for optimum performance.
See "git help gc" for manual housekeeping.
It appears to print this every time if I do a git fetchrepeatedly, even when there are no changes and nothing for git fetchto do. This doesn't make a lot of sense to me. It also seems to happen with other network operations, such as git pushand git pull.
如果我git fetch反复执行，似乎每次都会打印此内容，即使没有更改也无事可做git fetch。这对我来说没有多大意义。它似乎也发生在其他网络操作中，例如git push和git pull。
The command returns back to the prompt instantly with no further output, and I cannot find any git process running on my machine. It seems to happen only with this repository, and only on this machine. git config -l | grep gcreturns nothing.
该命令立即返回到提示符，没有进一步的输出，而且我找不到任何在我的机器上运行的 git 进程。它似乎只发生在这个存储库中，并且只发生在这台机器上。git config -l | grep gc什么都不返回。
What can I do to diagnose or fix this problem?
我能做些什么来诊断或解决这个问题？
$ git --version

I found the solution from the second comment you provided, Trengot, thanks. It turns out that I had some dangling blobs, which were in .git/objects/17and hence triggering the packing:
我从你提供的第二条评论中找到了解决方案，Trengot，谢谢。事实证明，我有一些悬空的斑点，它们在里面.git/objects/17并因此触发了包装：
$ git fsck
dangling blob d9ff0aeac4aa8b4e0907daed675ebf60278bc977
dangling blob dbff2d073741f9775c815d4a3c623736af224dad
dangling blob e1ffbab1c5b985cd1cd3bc0281075ea2ed80744a
dangling blob fdff59878ccb3a75689f4acca615cfb635288774
This cleaned them up:
这清理了它们：
$ git gc --prune=now
Be aware, as per Henrik's comment below, this may be a little dangerous. Take care!
请注意，根据下面 Henrik 的评论，这可能有点危险。小心！
