二、安装msmtp和git-email
点击左边栏的“软件中心”，在搜索框中输入“msmtp”，选择安装即可，如下图所示。
“git-email”安装同理。
三、配置msmtp
1、请按照如下步骤配置msmtp：
|
root@-VirtualBox:~# cd ~/ root@-VirtualBox:~# vi .msmtp.log //创建log文件，然后直接退出 root@-VirtualBox:~# vi .msmtprc //键入如下内容 defaults
logfile ~/.msmtp.log
# samsung account samsung protocol smtp host smtp.samsung.com from cb.xiong@samsung.com user cb.xiong@samsung.com password xxxxxx // single的密码，由于single密码3个月一换，注意同步更新此处 port 25 auth plain tls off #tls_starttls on #tls_trust_file /etc/ssl/certs/ca-certificates.crt #syslog LOG_MAIL
# Set a default account account default : samsung
root@-VirtualBox:~# chmod 600 .msmtprc //这个执行下否则会 错
|
2、验证msmtp是否可以使用
使用如下命令向自己的single邮箱发送一个邮件，确认是否可以使用。
|
root@-VirtualBox:~# msmtp cb.xiong@samsung.com nihao //输入任意内容，然后按ctrl+D退出 root@-VirtualBox:~# |
如果自己的single邮箱收到了本邮件说明配置成功，若没有，请检查虚拟机的 络配置。
3、关于single邮箱服务器（了解即可）
|
root@-VirtualBox:~# msmtp –serverinfo –host=smtp.samsung.com SMTP server at smtp.samsung.com ([203.254.227.15]), port 25: mmp1.samsung.com — Server ESMTP (Oracle Communications Messaging Server 7u4-24.01(7.0.4.24.0) 64bit (built Nov 17 2011)) Capabilities: SIZE 0: Maximum message size is unlimited PIPELINING: Support for command grouping for faster transmission ETRN: Support for RMQS (Remote Message Queue Starting) DSN: Support for Delivery Status Notifications AUTH: Supported authentication methods: PLAIN LOGIN root@-VirtualBox:~# root@-VirtualBox:~# msmtp –serverinfo –host=smtp.samsung.com –tls=on –tls-certcheck=off msmtp: the server does not support TLS via the STARTTLS command |
四、配置git
|
$git config –global user.name ‘Changbing Xiong’ $git config –global user.email ‘ cb.xiong@samsung.com’ $git config –global sendemail.chainreplyto false $git config –global sendemail.smtpserver /usr/bin/msmtp |
查看配置结果是否正确：
|
# cat ~/.gitconfig [user] name = Changbing Xiong email = cb.xiong@samsung.com [color] ui = auto [core] editor = vim [sendemail] chainreplyto = false smtpserver = /usr/bin/msmtp root@-VirtualBox: |
五、订阅mailinglist
Linux开源分支要求开发者上传patch或者driver时，需要将邮件抄送给mailinglist、maintainer和其他人，首先需要订阅相关子系统的mailinglist。
|
订阅邮件列表mailing list：//改成自己所要提交代码所在子系统的mailing list，详见linux代码根目录下的MAINTAINERS文档
To: majordomo@vger.kernel.org 邮件内容： subscribe linux-media
取消订阅邮件列表mailing list： To: majordomo@vger.kernel.org 邮件内容： unsubscribe linux-media |
注意：订阅mailinglist的邮件不需要标题，请参考如下方式：
|
# vi subscrible Subject: //冒 后面保留一个空格 //必须空一行，并且该行不要有空格 subscribe linux-media //在这里加个回车，然后退出并保存文件
#git send-email –from cb.xiong@samsung.com –to cb.xiong@samsung.com ./subscrible //验证一下 #git send-email –from cb.xiong@samsung.com –to majordomo@vger.kernel.org ./subscrible |
注意：发送完subscribe邮件后，你会收到一封确认邮件，比如我的确认邮件标题为“Confirmationfor subscribe linux-media”，里面有认证信息，请按照邮件内容，再发一个认证邮件给majordomo@vger.kernel.org，如下：
|
# vi subscrible_auth Subject:
auth xxxxxxxx subscribe linux-media cb.xiong@samsung.com
# git send-email –from cb.xiong@samsung.com –to majordomo@vger.kernel.org ./subscrible_auth |
六、生成patch
本章介绍如何生成符合开源 区要求的patch格式。
1、在git分支上修改代码
2、gitadd 修改后的代码
3、gitcommit -s
第一次commit时使用-s，后面修改下面内容时，用—amend即可。
|
au0828: fix logic of tuner disconnection //标题，带上模块名称，如au0828 //此处必须空一行 The driver crashed when the tuner was disconnected while restart stream operations are still being performed. Fixed by adding a flag in struct au0828_dvb to indicate whether restart stream operations can be performed.
If the stream gets misaligned, the work of restart stream operations are usually scheduled for many times in a row. If tuner is disconnected at this time and some of restart stream operations are still not flushed, then the driver crashed due to accessing the resource which used in restart stream operations has been released. //此处必须空一行 Signed-off-by: Changbing Xiong
# Please enter the commit message for your changes. Lines starting //从这往下都是自动生成，勿动 # with ‘#’ will be ignored, and an empty message aborts the commit. # On branch tizen # Your branch is ahead of ‘origin/tizen’ by 1 commit. # # Changes to be committed: # (use “git reset HEAD^1 # # modified: drivers/media/usb/au0828/au0828-dvb.c # modified: drivers/media/usb/au0828/au0828.h |
4、gitformat-patch HEAD^
将最近一次的修改生成一个patch
|
root@-VirtualBox:/home/samba/odroidx2/linux-3.10# git format-patch HEAD^ 0001-au0828-fix-logic-of-tuner-disconnection.patch root@-VirtualBox:/home/samba/odroidx2/linux-3.10# cat 0001-au0828-fix-logic-of-tuner-disconnection.patch From cc4f6646ae5eb0d75d56cca62e2d60c1ac8cad66 Mon Sep 17 00:00:00 2001 From: Changbing Xiong Date: Tue, 22 Apr 2014 16:10:29 +0800 Subject: [PATCH] au0828: fix logic of tuner disconnection //此处的[PATCH]是工具自动加上的
The driver crashed when the tuner was disconnected while restart stream 。。。。。。。 restart stream operations has been released.
Change-Id: Iaa1b93f4d5b08652921069182cdd682aba151dbf //需要通过vim删除此行 Signed-off-by: Changbing Xiong — drivers/media/usb/au0828/au0828-dvb.c | 13 +++++++++++++ 。。。。。。。 root@-VirtualBox:/home/samba/odroidx2/linux-3.10# |
注：如果patch中有Change-Id行，需要删除；用 branch和master 比较产生patch的方法：
git format-patch -C -n master ..$dev_branch
将最近两次的修改的内容生成两个独立的patch。
其中patch2是在patch1的基础上修改的，这种情况下，patch1和patch2是连续的，在patch的标题上面有规范要求，见下：
|

5、检查patch
|
root@-VirtualBox:/home/samba/odroidx2/linux-3.10# ./scripts/checkpatch.pl -f 0001-au0828-fix-logic-of-tuner-disconnection.patch -terse 0001-au0828-fix-logic-of-tuner-disconnection.patch:31: ERROR: trailing whitespace 0001-au0828-fix-logic-of-tuner-disconnection.patch:33: ERROR: trailing whitespace 0001-au0828-fix-logic-of-tuner-disconnection.patch:43: ERROR: trailing whitespace 0001-au0828-fix-logic-of-tuner-disconnection.patch:45: ERROR: trailing whitespace 0001-au0828-fix-logic-of-tuner-disconnection.patch:49: ERROR: trailing whitespace 0001-au0828-fix-logic-of-tuner-disconnection.patch:54: ERROR: trailing whitespace 0001-au0828-fix-logic-of-tuner-disconnection.patch:69: ERROR: trailing whitespace 0001-au0828-fix-logic-of-tuner-disconnection.patch:83: ERROR: trailing whitespace 0001-au0828-fix-logic-of-tuner-disconnection.patch:85: ERROR: trailing whitespace total: 9 errors, 0 warnings, 87 lines checked root@-VirtualBox:/home/samba/odroidx2/linux-3.10# |
行未有空格（原文件中没有，不知道为什么生成的patch中有了空格），可以用sed工具删除
|
#sed -e ‘s/[ ]*$//g’ 0001-au0828-fix-logic-of-tuner-disconnection.patch>1.patch //保存到新patch中 root@-VirtualBox:/home/samba/odroidx2/linux-3.10# ./scripts/checkpatch.pl -f 1.patch –terse root@-VirtualBox:/home/samba/odroidx2/linux-3.10# |
6、发送patch
注意：
邮件外发需要申请“邮件外发”权限；
强烈建议下发一个邮件给自己，看些收到的邮件格式是否符合linux要求；
已经订阅了mailinglist；
patch经过相关的专利、lincense检查；
|
root@-VirtualBox:/home/samba/odroidx2/linux-3.10# git send-email –to cb.xiong@samsung.com 1.patch //先自己验证下
root@-VirtualBox:/home/samba/odroidx2/linux-3.10# git send-email –no-chain-reply-to –suppress-from –no-signed-off-by-cc –to linux-media@vger.kernel.org –cc m.chehab@samsung.com –cc dheitmueller@kernellabs.com 1.patch root@-VirtualBox:/home/samba/odroidx2/linux-3.10# git send-email –no-chain-reply-to –suppress-from –no-signed-off-by-cc –to linux-media@vger.kernel.org –cc m.chehab@samsung.com –cc dheitmueller@kernellabs.com 2.patch
|
git send-email –no-chain-reply-to–suppress-from –no-signed-off-by-cc –to cb.xiong@samsung.com your.patch
不要嵌套 发给自己 不要发送给signed-off-by的人
效果如下：
另外也可以在http://www.spinics.net/lists/linux-media/中看到自己提交的patch。
Adding Patch Version Information：
Adding Extra Notes to Patch Mails：
Sometimes it’s convenient to annotate patches withsome notes that are not meant to be included in the commit message. Forexample, one might want to write “I’m not sure if this should be committedyet, because…” in a patch, but the text doesn’t make sense in the commitmessage. Such messages can be written below the three dashes “—“that are in every patch after the commit message.Use the –annotate option with git send-email to be ableto edit the mails before they are sent.
