TM/Git Workflows

Installation

Windows Install

1. Install Tortoise Git. Not a must-have but helpful. Recommended to install this first.
2. Install Msysgit as per the Tortoise Git instructions. Not a must-have but strongly recommended from the start, in order to be consistent between egit and commandline.
3. Launch Git Bash
   • If it is slow for you, you may want to set a HOME environment variable to a local disk and update the Git Bash program shortcut
     • For me, the default %HOMEDRIVE%%HOMEPATH% pointed to a non-existing remote folder, making everything dead slow
     • So I've set HOME=D:/Workspaces/git -- all your git repos will be below there by default, and your user config too
   • Re-start Git Bash to verify it is fast and HOME is accurate
4. Set up your user ID on git bash as per Git#Committers_new_to_Git.
   • Eclipse Committers who don't want to expose their E-Mail Address can use their committerid instead of the E-Mail address.

  git config --global user.email my_committer_email@address.com
  git config --global user.name "John Doe"
  git config --global branch.autosetuprebase always

1. Launch Eclipse SDK and install latest Egit from http://download.eclipse.org/egit/updates
   • Check Preferences > Team > Git > Configuration whether it picked up your commandline settings
     • May need to specify Location of Msysgit install in System Settings
     • May want to update Default Repository Folder in Git : Cloning Repositories
     • In user settings, verify branch.autosetuprebase = always as per Platform-releng/Git_Workflows#Configure_the_workspace
     • In Preferences > General > Workspace, set New text file line delimiter to Unix
   • Check Preferences > General > Network > SSH2 home directory
     • Set to your $HOME/.ssh in order to share with Msysgit - or copy the $HOME/.ssh folder
     • Generate a private/public key pair if necessary (in the UI, or on Git Bash as per below link)
     • Upload your Gerrit#SSH_Keys - using a passphrase is recommended
2. Set up SSH private key for Tortoise Git (this is re-used by Egit)
   • Launch C:\Program Files\TortoiseGit\bin\puttygen.exe to load your openssh private key and convert into a putty private key in your home/.ssh
   • Launch C:\Program Files\TortoiseGit\bin\pageant.exe ; right-click the icon in taskbar and load your putty private key (agent will serve Egit, Msysgit and Tortoisegit)
     • Recommend placing a link for pageant on your desktop to ensure SSH authentication with your private key
     • NOTE Inside Egit this should also be possible somehow internal with JSch / Jgit but I did not get it to work

Linux Install

This is a subset of the Windows install since more settings will be appropriate by default.

1. Set up your user ID on git commandline as per Git#Committers_new_to_Git

  git config --global user.email my_committer_email@address.com
  git config --global user.name "John Doe"
  git config --global branch.autosetuprebase always

1. Launch Eclipse SDK and install latest Egit from http://download.eclipse.org/egit/updates
   • • In user settings, set branch.autosetuprebase = always as per Platform-releng/Git_Workflows#Configure_the_workspace
   • Upload your Gerrit#SSH_Keys

Cloning the Repo

• Optiona A (Recommended): Using EGit and File > Import > Team > Team Project Set:
  • Committers import tm-all-committer.psf
  • Users/Contributors import tm-all-anonymous.psf

• Optiona B - Commandline:

 cd $HOME/git
 git clone ssh://userid@git.eclipse.org:29418/tm/org.eclipse.tm.git
 #readonly:# git clone git://git.eclipse.org/gitroot/tm/org.eclipse.tm.git
 git clone ssh://committer_id@git.eclipse.org/gitroot/www.eclipse.org/tm.git
 #readonly:# git clone http://git.eclipse.org/gitroot/www.eclipse.org/tm.git

• Option C - Plain Egit UI - Refer to EGit/User Guide for more detailed instructions
  • File > Import > Git : Projects from Git
    • URI, Next, Paste URL: ssh://userid@git.eclipse.org:29418/tm/org.eclipse.tm.git, Edit userid, Next
      • Read-only contributors paste git://git.eclipse.org/gitroot/tm/org.eclipse.tm.git
    • Import projects from file system as needed, next
  • If desired, import the website repository the same way
• For contributing to the Simultaneous Release, see Simrel/Contributing_to_Simrel_Aggregation_Build#Get_the_simrel.build_project

Configure the workspace

[This section originally copied from Platform-releng/Git_Workflows#Configure_the_workspace.

Open the Team > Git > Configuration preference page and select the User Settings tab.

• Verify entries for user.name and user.email. If you don't want to share your e-mail you can also use your committer account ID. Note that you will not be able to push changes to the repository if the latter property is not matching with your records at the Eclipse Foundation.
• Verify entry branch.autosetuprebase = always

On the General > Workspace preference page, set New text file line delimiter to Unix.

Set up JRE's, Target Platform and API Baseline as per TM/Code Streams

Configuring the repo

This section originally copied from Platform-releng/Git_Workflows#Configuring_the_repo.

Make sure that you set core.autocrlf = false and on Windows core.filemode = false. If you use EGit to clone the repository then the latter is done automatically for you.

Unless you are working on topic branches, we work in a fairly linear history. Please make sure branch.branchname.rebase = true is set. If you've set branch.autosetuprebase = always as explained in #Configure_the_workspace, then this is done automatically.

Otherwise, once you've cloned a repository, you can go to the Preferences > Team > Git > Configuration page. Select your repository, select the branch you picked when you cloned the repository, and click New Entry.... Append "rebase" to the text in the 'Key' field and enter "true" as value.
