git repo 管理
有一個使用情形是用 repo管理
已經出一版 1.0 sdk了。
如果是有patch的話想只出1.01有修改的檔案
如 project a 的 ddd.c 和 project b的 eee.c
是不是有對應的指令可以做到
repo forall -c 'git diff --src-prefix=old/$REPO_PATH/ --dst-prefix=new/$REPO_PATH/ v1.0 v1.0.1' > all.patch
This command generates a single patch for the change from v1.0 to v1.0.1 tags.
將有修改後的檔案 tar起來。
single tar file:: files the change from v1.0 to v1.0.1 tags.
List file different to `filelist`
$ repo forall -c 'git diff HEAD v1.0.1 v1.0 --name-only | sed -e "s|^|$REPO_PATH/|"' > filelist
Create tarball according to `filelist`
$ tar jcvf test.tar.bz2 `cat filelist`

The repo manifest command creates manifest files with fixed SHA-1s based on the current workspace.
repo manifest -r -o my-manifest.xml
只用git管理的情形

repo sync -j threadcount
-j threadcount ：在線程之間拆分同步，以加快完成速度。確保不要通過為其他任務保留一些CPU來壓倒計算機。要查看可用CPU的數量，請首先運行： nproc --all
git push origin master
1.
直接 push:
$ git push orgin default:master
2.
進到 code review的push 指令
git push origin default:refs/for/master
PS. 其實 repo upload 指令，就是把 topic branch push 到 refs/for/project-branch，
就會直接進到 code-review 頁面上
tig
m main view
d diff view
r branch view the branches, remotes and tags in the repository.
t tree view
b blame view Displays the file content annotated or blamed by commits.
all view
j k up/down
J K next/previous
上鍵 下鍵 next/previous
page up/down : page up down
q 關閉 畫面
in main view
D 切換 date display modes
A 切換 author display modes
X 切換 commit sha
enter 查看 commit 的詳細 diff 變更
q 關閉 diff 畫面。
還有 tig 指令後面接 branch 名稱可以直接查看分支，接著在分支 commit 上按大寫 C 可以 cherry-pick 回目前的 branch，而 tig 後面接檔名的話可以直接查看跟這個檔案有關的 commit，更多的基本功能介紹可以看 git? tig! 這篇文章。
