Git日志不显示子模块更改

我对主哈希6877146进行了提交，该哈希更新了一个子模块。

$ git show 6877146
commit 6877146f1781bfbd4ec3ae2a27121a606f5f688e
Author: [snip]
Date:   Wed Feb 22 16:10:20 2012 +0000

    updating potatobase

diff --git a/potatobase b/potatobase

+Subproject commit b77ba624d6a1c5e62d434ad2d06383604aeab431

该提交位于master分支上，我目前已 check out 该分支:

$ git branch -a --contains 6877146
* master
  remotes/origin/HEAD -> origin/master
  remotes/origin/master
  remotes/origin/ticket-1479-refactor-blade-json-functions

但是，在子模块上执行git log不会显示提交:

$ git log potatobase | grep 6877146
$

如果我明确 checkout 此提交，则它在日志中:

$ git checkout 6877146
$ git log potatobase | grep 6877146
commit 6877146f1781bfbd4ec3ae2a27121a606f5f688e

我 check out master后，为什么该提交未在日志中显示？它已经 merge 到母版中:

$ git checkout master
$ git merge 6877146
Already up-to-date.
$

最佳答案

当您初始化/更新子模块时，提交更新子模块的提交只会更改修订版git将会 checkout 。该提交的提交ID与子模块本身的提交ID毫无关系。
