git am 操作

# git am 操作 #

*  我们在做git操作的时候，为了保留`git log`的记录，我们在做`patch`的时候会使用`git format patch`的命令来生成一个`patch`，在应用`patch`的时候会选择`git am`来打上patch。我们打上的`patch`一般会包含N个文件的补丁，假设这N个文件中有一个文件发生了conflict，那么am的过程就会停止，这时候需要我们手动去解决conflict，然后才能继续。

--------------------

## patch文件 ##

*  生成patch文件的操作如下:

$ git format-patch HEAD^		#生成最近的1次commit的patch
    $ git format-patch HEAD^^		#生成最近的2次commit的patch
    $ git format-patch HEAD^^^	# 生成最近的3次commit的patch
    $ git format-patch HEAD^^^^	# 生成最近的4次commit的patch
    $ git format-patch <r1>..<r2>	# 生成两个commit间的修改的patch(包含两个commit。<r1>和<r2>都是具体的commit号)
    $ git format-patch <r1>			# 生成某commit以来的修改patch(不包含该commit)
    $ git format-patch --root <r1>	# 生成从根到r1提交的所有patch

*  Example
 *  查看日志记录如下:

        ESFIX: Fix exited horizon when created alarm sometimes
        
        It needs to get alarm notify list when created alarm,
        while getting notify list should call keystone api to
        get user information. It needs to judge request.user
        whether is superuser which is used to initialize
        keystoneclient and use policy to judge privileges if
        the user is superuser. The reason is that the logic of
        judging whether the user is superuser sometimes use the
        project role of this user, while using policy to judge
        privileges use the domain role of this user. So if this
        user has admin project role and member domain role which
        may result in this problem. This is due to incorrect usage
        about using is_superuser api to judge whether this user is
        cloud admin. So it needs to edit code that uses
        api.keystone.is_cloud_admin to judge whether this user is
        cloud admin which can keep same logic during all the process
        of code.

    Subject: [PATCH 2/2] ESFIX: Fix exited horizon when created alarm sometimes
    
    It needs to get alarm notify list when created alarm,
    while getting notify list should call keystone api to
    get user information. It needs to judge request.user
    whether is superuser which is used to initialize
    keystoneclient and use policy to judge privileges if
    the user is superuser. The reason is that the logic of
    judging whether the user is superuser sometimes use the
    project role of this user, while using policy to judge
    privileges use the domain role of this user. So if this
    user has admin project role and member domain role which
    may result in this problem. This is due to incorrect usage
    about using is_superuser api to judge whether this user is
    cloud admin. So it needs to edit code that uses
    api.keystone.is_cloud_admin to judge whether this user is
    cloud admin which can keep same logic during all the process
    of code.

*  由实例可以看出生成Patch的相应操作。

--------------------

## git am patch文件 ##

*  当我们生成patch文件之后，我们需要将patch文件合并到相应的分支中。一系列操作如下:

$ git apply --stat 0001-fix-bug-error-of-export-billing.patch		# 查看patch的情况
    $ git check --stat 0001-fix-bug-error-of-export-billing.patch	# 检查patch是否能够打上，如果没有任何输出，则说明无冲突，可以打上。
    (注意: git apply 是另外一种打patch的命令，其与git am的区别是, git apply 并不会将commit message等打上去，打完patch之后需要重新git add 和 git commit，而git am会直接将patch的所有信息打上去，而且不用重新git add和git commit，author也是patch的author而不是打patch的人)
    $ git am 0001-fix-bug-error-of-export-billing.patch					# 将名0001-fix-bug-error-of-export-billing.patch字为0001-fix-bug-error-of-export-billing.patch的patch打上
    $ git am --signoff 0001-fix-bug-error-of-export-billing.patch 	# 添加-s或者--signoff，还可以把自己的名字添加为signed off by信息，作用是注明打patch的人是谁，因为有时打patch的人并不是patch的作者。
    $ git am ~/patch-set/*.patch													# 将路径~/patch-set/*.patch 按照先后顺序打上
    $ git am --abort																		# 当git am失败时，用以将已经在am过程中打上的patch废弃掉(比如有三个patch，打到第三个patch时有冲突，那么这条命令会把打上的前两个patch丢弃掉，返回没有打patch的状态)
    $ git am --resolved																	# 	git am失败，解决完冲突后，这条命令会接着打patch

--------------------

### git am patch文件冲突 ###

*  git am patch文件操作

    Applying: Configuration for on and off creat instance from image
    error: patch failed: easystack_dashboard/settings.py:149
    error: easystack_dashboard/settings.py: patch does not apply
    Patch failed at 0001 Configuration for on and off creat instance from image
    The copy of the patch that failed is found in: .git/rebase-apply/patch
    When you have resolved this problem, run "git am --continue".
    If you prefer to skip this patch, run "git am --skip" instead.
    To restore the original branch and stop patching, run "git am --abort".

--------------------

### 解决冲突的方案 ###

#### 方案一: 如果不想打这一系列patch了 ####

jackdan@jackdan-ThinkPad-T430:~/work/fp10/horizon$ git am --abort

#### 方案二 ####

(1) 根据git am失败的信息，找到发生冲突的具体patch文件，然后用命令`git apply --reject <patch_name>`，强行打这个patch，发生冲突的部分会保存为.rej文件（例如发生冲突的文件是a.txt，那么运行完这个命令后，发生conflict的部分会保存为a.txt.rej），未发生冲突的部分会成功打上patch  
(2) 根据.rej文件，通过编辑该patch文件的方式解决冲突。  
(3) 废弃上一条am命令已经打了的patch：git am --abort  
(4) 重新打patch：git am ~/patch-set/\*.patchpatch

#### 方案三 ####

(1) 根据git am失败的信息，找到发生冲突的具体patch文件，然后用命令`git apply --reject <patch_name>`，强行打这个patch，发生冲突的部分会保存为.rej文件（例如发生冲突的文件是a.txt，那么运行完这个命令后，发生conflict的部分会保存为a.txt.rej），未发生冲突的部分会成功打上patch  
(2) 根据.rej文件，通过编辑发生冲突的code文件的方式解决冲突。  
(3) 将该patch涉及到的所有文件（不仅仅是发生冲突的文件）通过命令`git add <file_name>`添加到工作区中  
(4) 告诉git冲突已经解决，继续打`patch: git am --resolved (git am --resolved)` 和 `git am --continue`是一样的)

> 方案二和方案三主要区别是解决冲突的方法不一样。  
> 方案二是通过编辑patch文件的方式解决冲突；  
> 方案三是通过编辑冲突code文件的方式解决冲突。  
> 这两种方案区别比较大：经过实验，核心区别在于，方案三无法验证冲突有没有切实的解决。即使你在方案三的第二步乱改一通，也能“打完”发生冲突的patch（并没有检测修改后的code文件跟patch期望的是否相同）。因此，如果采用方案三，那么再解决code文件冲突后，需要人工去确认修改的正确性。

*  **推荐方案二作为解决合并patch冲突的方案**。
