Question

我想在系统历史记录的子目录中找到更改。为此，我使用

git log -- $subdirectory

根据this，这就足够了。在“git log - $ subdirectory”的结果中有一些不显示的提交;但根据

git show $sha

，他们更改了子目录。

例如，当我使用

查看apache-accumulo提交时，在this中

git show 31ee26b8ac41844f2a647a5d1484f47da731872a

，我发现它改变了“core / src / main”。更具体地说，我得到以下回复

而

git log -- core/src/main | grep 31ee26b8ac41844f2a647a5d1484f47da731872a

没有显示提交。

我找不到任何答案！我很感激任何见解！谢谢！

首先，apache/accumulo中没有.gitmodules个文件，因此我们根本不是在讨论 git submodules 。相反，您可以考虑记录子文件夹或子目录。不是子模块。

第二

C:\Users\vonc\prog\git\accumulo>git show --name-only 31ee26b8a

    ACCUMULO-3423 fixed replication bugs with recent refactorings in StatusUtil

core/src/main/java/org/apache/accumulo/core/replication/StatusUtil.java
server/tserver/src/main/java/org/apache/accumulo/tserver/log/TabletServerLogger.java

这是指StatusUtil.java，现在位于src/main/java/org/apache/accumulo/server/replication

换句话说，该文件在提交后已移动， git log默认只列出重命名的文件。

将--follow添加到git log：

C:\Users\vonc\prog\git\accumulo>git log --graph --all --oneline --decorate  --follow -- core\src\main |grep 31ee26
| * | | | | | | | | | | | | | | | | | 31ee26b8a ACCUMULO-3423 fixed replication bugs with recent refactorings in StatusUtil

或者：

C:\Users\vonc\prog\git\accumulo>git log --follow -- core\src\main|grep 31ee26
commit 31ee26b8ac41844f2a647a5d1484f47da731872a

请参阅＆＃34; Why might git log not show history for a moved file, and what can I do about it?＆＃34;

跟踪子目录中的更改时，“git show”和“git log - ”之间的不一致
