HowtoBeginGroupDeveloping ========================= !!NOTE!! Git Official - <http://git-scm.com/> Github - <http://github.com/> Actually, you can get all the help you need from <http://help.github.com/> Text below is just a rough conclusion, which may even be incorrect. Step 0 Install and Setup Git ---------------------------- In Fedora sudo yum install git gitk Or in Ubuntu sudo apt-get install git gitk Then git config --global user.name YOUR_NAME git config --global user.email 'YOUR_EMAIL' e.g. A new user named rescue, do it like git config --global user.name rescue git config --global user.email 'email@example.com' Then you can see your info by typing in git config --global --list As like: [rescue@leafgrass workspace]$ git config --global user.name rescue [rescue@leafgrass workspace]$ git config --global user.email 'firstname.lastname@example.org' [rescue@leafgrass workspace]$ git config --global --list user.name=rescue email@example.com [rescue@leafgrass workspace]$ Step 1 Signup at Github ----------------------- Nothing much to say :) Step 2 Fork A Project Repo and Work on It ----------------------------------------- Go to LeafGrass github page, choose repo "grouoptest", then click on "Fork" button on up right of the page. Wait a minute, this repo will be forked. OK, for now, you've forked a project from organization LeafGrass. Click "Dashboard" to go to your own github page and choose the repo you've just forked. See? There is a line represent for address of this repo, like: firstname.lastname@example.org:rescue/grouptest.git Ok, in your local command line, run git clone email@example.com:rescue/grouptest.git Then, I guess you'll meet a problem below, like: [rescue@leafgrass workspace]$ git clone firstname.lastname@example.org:rescue/grouptest.git Cloning into grouptest... The authenticity of host 'github.com (22.214.171.124)' can't be established. RSA key fingerprint is 16:27:ac:a5:76:28:2d:36:63:1b:56:4d:eb:df:a6:48. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added 'github.com,126.96.36.199' (RSA) to the list of known hosts. Permission denied (publickey). fatal: The remote end hung up unexpectedly This is because you don't have SSH keys. Everyone need a private key and a public key for himself, and may get many other's public keys, so people can work and communicate together. Follow these steps in link below, you can resolve it. <http://help.github.com/linux-set-up-git/> e.g. [rescue@leafgrass workspace]$ cd ~/.ssh/ [rescue@leafgrass .ssh]$ ls known_hosts [rescue@leafgrass .ssh]$ ssh-keygen -t rsa -C email@example.com Generating public/private rsa key pair. Enter file in which to save the key (/home/rescue/.ssh/id_rsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /home/rescue/.ssh/id_rsa. Your public key has been saved in /home/rescue/.ssh/id_rsa.pub. The key fingerprint is: d6:2d:09:1f:32:c6:c7:d2:b7:c5:74:a3:ef:9d:f1:ea firstname.lastname@example.org The key's randomart image is: +--[ RSA 2048]----+ | ...| | . o o...| | B = ..o | | . O = o. | | S = o o | | . . . =| | oo| | . | | .E | +-----------------+ [rescue@leafgrass .ssh]$ cat id_rsa.pub ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDOXdY5RscN1gumTa0ZqNfTJ631WsK6Nwlaj9Bofk38kqLa6hI5RQ5SrmGG1EIH22is1wa1xCpSg2I6villDCUwfZcDc5ecyThLmaq44jip7Vle85LU3oSpJ/3Ak2ve/hP/ZrF4lZsd9fdvWwsj8jce2ZAspgrQELvAzfc7MqUWcBKyRuSQgwaWJLd1SozIn7Bm7BoHkTsaVo7qoKxrV+BSHY7/N/pPYXBkfZjXett0p2rBst7gBIKOB/vKesI9tK/lG8iAKnGTOAWJuCyxYwAWKjeJ2W1enGzf6m1tmzj3jJfvl2hLAlcyqYS1e6MUGyD0Hbn3aH0t9mcRwRThc6wx email@example.com [rescue@leafgrass .ssh]$ On the GitHub site Click “Account Settings” > Click “SSH Public Keys” > Click “Add another public key”. Copy the WHOLE output string like above to the "Key" field. ("Title" is not neccessary.) Then click on "Add key", everything is ok. The "clone" action can be done now. e.g. [rescue@leafgrass workspace]$ git clone firstname.lastname@example.org:rescue/grouptest.git Cloning into grouptest... remote: Counting objects: 6, done. remote: Compressing objects: 100% (5/5), done. remote: Total 6 (delta 1), reused 6 (delta 1) Receiving objects: 100% (6/6), 25.11 KiB, done. Resolving deltas: 100% (1/1), done. [rescue@leafgrass workspace]$ ls grouptest OK? Go forward next step. Step 3 Basic Working on Local ----------------------------- cd grouptest git pull [do some changes] git add . git status git commit -a [type in your commit comment] git push e.g. [rescue@leafgrass grouptest]$ git pull Already up-to-date. [rescue@leafgrass grouptest]$ ls license.md markdown.pl readme.md syntax.md [rescue@leafgrass grouptest]$ echo testing > test.md [rescue@leafgrass grouptest]$ ls license.md markdown.pl readme.md syntax.md test.md [rescue@leafgrass grouptest]$ git add . [rescue@leafgrass grouptest]$ git status # On branch master # Changes to be committed: # (use "git reset HEAD <file>..." to unstage) # # new file: test.md # [rescue@leafgrass grouptest]$ git commit -a [master 0cc4938] test 1 files changed, 12 insertions(+), 0 deletions(-) create mode 100644 test.md [rescue@leafgrass grouptest]$ git push Counting objects: 4, done. Delta compression using up to 2 threads. Compressing objects: 100% (3/3), done. Writing objects: 100% (3/3), 300 bytes, done. Total 3 (delta 1), reused 0 (delta 0) To email@example.com:rescue/grouptest.git d0bc323..0cc4938 master -> master [rescue@leafgrass grouptest]$ Well, now turn to you github page and you'll see all your changes. Actually, that's all for regular code updating, modifying and uploading. Please see git documents for detailed information of these commands and other advanced usage. Step 4 Pull Request ------------------- Two terms here: push and pull. push: After you commit your changes in you local repo, "push" will upload your changes to the server(that is, our repository) and do an auto-merge. pull: Download the latest files from server to your local repo(in fact, current branch) then do an auto-merge, too. On the page of your github repo, click on the "Pull Request" up right. Then it will prompt a new page require you to fill in the requesting message, just like writing an E-Mail. Actually in this step, you are requesting the administrator of the repo you just forked to merge your changes into the main repo in Organization LeafGrass. Then you can see a line like this on github page: rescue wants someone to merge 1 commit into LeafGrass:master from rescue:master Thus, the repo administrator will receive an E-Mail and decide to merge or not. Why pull request instead of direct push? Look at this page - <http://help.github.com/send-pull-requests/> Step 4 Keep Your Repo Up-To-Date with Organization -------------------------------------------------- Run these commands in your repo directory, e.g. git remote add upstream firstname.lastname@example.org:LeafGrass/grouptest.git Then run (auto-merge) git pull upstream master OR (manual merge) git fetch upstream git merge upstream/master That's all for you to keep your working branch up-to-date. For detailed information about differences between "fetch" and "pull", refer to <http://help.github.com/fork-a-repo/> What is the difference between fetch and pull? Step 5 Development in the Future -------------------------------- After we get to be familiar with this fast version control system - Git, each of us developers need a direct acess to the base repo for a faster developing process. Thus, one can create his own branch based on the latest master(trunk), and works on it. Developing new features or fixing bugs will be done on this branch. Ofcourse, he SHOULD take charge of his branch's healthy. As this specific feature is implemented or bug is fixed, and passed the testing, We can merge it to our trunk - master. Let's do to help the source tree growing up ... Thanks.
