Git：“git fetch”报告的数字是什么意思？

运行 git fetch 时，会给出一些数字：

$ git fetch upstream
remote: Counting objects: 77, done.
remote: Compressing objects: 100% (23/23), done.
remote: Total 47 (delta 19), reused 39 (delta 11)
Unpacking objects: 100% (47/47), done.
From http://github.com/jbossas/jboss-as
ef19bd4..b5015c1  master     -> upstream/master

它们有什么用处吗？我想知道例如在该远程中发生了多少次提交。这些数据似乎不包含其中（在本例中为 5 次提交）。
（我知道我可以看到日志或其他任何东西；只是想知道那是做什么用的。）

原文

When running git fetch, that gives some numbers:

$ git fetch upstream
remote: Counting objects: 77, done.
remote: Compressing objects: 100% (23/23), done.
remote: Total 47 (delta 19), reused 39 (delta 11)
Unpacking objects: 100% (47/47), done.
From http://github.com/jbossas/jboss-as
ef19bd4..b5015c1  master     -> upstream/master

Are they useful in any way? I'd like to know e.g. how many commits was fetched happened in that remote. Which seems not to be contained in these data (in this case, it was 5 commits).
(I know I can see log or whatever to see that; just wonder what's that for.)

这是要获取（或必须获取）的对象数量。对象可以是以下任何内容：blob、tree、commit 或 tag。

因此，最简单的提交将由 2 个对象组成：commit 对象和（空）tree 对象。添加一个文件，你就得到了三个对象：commit+tree+blob。

要对获取的提交进行计数，请使用 git rev-list 来解析提交范围 ef19bd4..b5015c1：

git rev-list | wc -l

It's how many objects are going to be fetched (or had to be fetched). An object can be anything of: blob, tree, commit or tag.

So, the most simplest commit would be composed of 2 objects: The commit object and the (empty) tree object. Add one file, and you've got three objects: commit+tree+blob.

To count the fetched commits, use git rev-list to parse the commit range ef19bd4..b5015c1:
