当解决方案是删除冲突文件时，有没有办法让 git rerere 工作？

Question

这是交易。 master 有一个文件，file1。我分支，并删除分支中的那个文件。同时，我在 master 上修改 file1。轰，冲突。

当我将我的分支合并到 master 时，解决方案是删除该文件。我正在尝试使用 git rerere 多次执行相同的分辨率，但正如您在下面看到的那样，它不会记录您删除文件时的分辨率。

我找不到关于此的任何文档，这只是 rerere 的限制吗？

 |system| brad-macbook-air in ~/tmp
± bb+ih |master ✓| → touch file1.txt

 |system| brad-macbook-air in ~/tmp
± bb+ih |master ✗| → git add . && git commit -m 'File1'
[master (root-commit) 95a807e] File1
 1 file changed, 0 insertions(+), 0 deletions(-)
 create mode 100644 file1.txt

 |system| brad-macbook-air in ~/tmp
± bb+ih |master ✓| → git checkout -b delete_file_1
Switched to a new branch 'delete_file_1'

 |system| brad-macbook-air in ~/tmp
± bb+ih |delete_file_1 ✓| → git rm file1.txt
rm 'file1.txt'

 |system| brad-macbook-air in ~/tmp
± bb+ih |delete_file_1 ✗| → git commit -m 'rm file1'
[delete_file_1 83d1a57] rm file1
 1 file changed, 0 insertions(+), 0 deletions(-)
 delete mode 100644 file1.txt

 |system| brad-macbook-air in ~/tmp
± bb+ih |delete_file_1 ✓| → git checkout master
Switched to branch 'master'

 |system| brad-macbook-air in ~/tmp
± bb+ih |master ✓| → echo 'hello' > file1.txt

 |system| brad-macbook-air in ~/tmp
± bb+ih |master ✗| → git commit -am 'update file1'
[master 16f6541] update file1
 1 file changed, 1 insertion(+)

 |system| brad-macbook-air in ~/tmp
± bb+ih |master ✓| → git merge delete_file_1 
CONFLICT (modify/delete): file1.txt deleted in delete_file_1 and modified in HEAD. Version HEAD of file1.txt left in tree.
Automatic merge failed; fix conflicts and then commit the result.

 |system| brad-macbook-air in ~/tmp
± bb+ih |master ✗| → git rm file1.txt
file1.txt: needs merge
rm 'file1.txt'

 |system| brad-macbook-air in ~/tmp
± bb+ih |master ✗| → git commit --no-edit
[master 4791204] Merge branch 'delete_file_1'

在这里我们应该看到类似 "recorded resolution for file1.txt" 的东西，但我们没有。为了确保它没有记录我们的决议，我们继续前进并再次进行完全相同的合并：

 |system| brad-macbook-air in ~/tmp
± bb+ih |master ✓| → git reset head^
Unstaged changes after reset:
D   file1.txt

 |system| brad-macbook-air in ~/tmp
± bb+ih |master ✗| → git co .

 |system| brad-macbook-air in ~/tmp
± bb+ih |master ✓| → git merge delete_file_1 
CONFLICT (modify/delete): file1.txt deleted in delete_file_1 and modified in HEAD. Version HEAD of file1.txt left in tree.
Automatic merge failed; fix conflicts and then commit the result.

在这里您可以看到 git rerere 不记得冲突解决方案（实际上错误地将文件留在树中）。

Answer 1

按照目前的情况，No.rerere 尝试根据每个冲突文件中的 hunk 记录以前的解决方案。在删除的情况下，rerere 仅将其视为没有要解决的问题。

Answer 2

当功能分支包含主分支中不存在的新文件时，我也遇到了问题，但是为了将功能分支合并到主分支中并使其正常工作，需要进行一些小修改到这个新文件。 git rerere 没有意识到这是整个合并过程的一部分，因此从不记录所需的更改。

当解决方案是删除冲突文件时，有没有办法让 git rerere 工作？

Is there a way to make git rerere work when the resolution is to delete the conflicted file?
