Eclipse and Git

• Note that use of this plugin is quite problematic in some cases, particular where users of only Git and users of the Hg-Git plugin are sharing a repository and creating branches. We're now recommending that users avoid this plugin if at all possible and stick to the Git console tools or Tortoise.

Mercurial+Git+Windows

One might do this to attempt to make MercurialEclipse work in Windows. Note that we have not yet successfully configured MercurialEclipse+hg-git+Windows and had it perform all functions (clone, synchronize) successfully, so for now recommend using TortoiseGit to do version control separately from Eclipse. That said, if you want to try, a few tips are: In MercurialEclipse you will need to go to Window>Preferences>Team>Mercurial and set the mercurial executable to use TortoiseHg\hg.exe instead of the bundled version.

Using TortoiseGit (Windows) with remote repositories

In order to install TortoiseGit:

1. Download and install Git for Windows from http://msysgit.googlecode.com/files/Git-1.7.0.2-preview20100309.exe.

You should disable all the options for shell integration, as this doubles up on what Tortoise provides. It's very hard to get rid of once you've installed it so it's important to omit here. I'd also disable the extra icons, which are unnecessary but easy to remove. On the next screens, I kept the default options.

2. Download and install TortoiseGit from http://code.google.com/p/tortoisegit/

3. After a restart, you should be able to clone a remote repository. A sample repository you can play with is located at:

git+ssh://okanagan.cs.ubc.ca/ubc/cs/project/arrow/git/Sample

You will need to provide SSH credentials for an account in klb group to access it. Remember to set the default umask of this account to (at most) 027, in order that others might see your work. NB: to set up a .ppk ssh key if you don't have one, see http://linux-sxs.org/networking/openssh.putty.html

You should set your user info in TortoiseGit so commits are properly attributed; go to Settings>Git to do this.

TortoiseGit usage notes

• many more commands are available in the TortoiseGit menu if you hold shift before right-clicking. For example, you must do this to delete a branch (Shift+Rclick>TortoiseGit>Browse Reference)

Mercurial and Git

Git

We have set up a common remote location for git repositories. These repositories are located on the netapp filesystem at /ubc/cs/project/arrow/git. Note that these should be bare remote repositories, and in particular should not have an associated working copy.

Members of the klb group should have permissions to work with repositories located here. Important: creators of / committers to Git repositories hosted here should ensure their default umask is 027 at most, to ensure that other klb users can read, write, and search their additions! To do this, edit either ~/.bashrc or ~/.cshrc (depending on whether you use BASH or CSh by default) and add the line umask 027.

A concise introduction to remote Git repositories for CVS users, which is the basis for many of these instructions, can be found at: http://www.kernel.org/pub/software/scm/git/docs/gitcvs-migration.html

CVS repository"> Importing a CVS repository

These instructions use the cvsimport script included with Git, and should be sufficient for migrating most papers, or other relatively simple repositories. A more powerful alternative involves use of cvs2git, and is not covered here.

For example, to import a CVS repository located at /ubc/cs/project/arrow/cvs/PAPER to a Git repo at ubc/cs/project/arrow/git/PAPER:

1. Ensure your CVSROOT environment variable is set appropriately; eg:

export CVSROOT=/ubc/cs/project/arrow/cvs

2. (optional) Ensure relevant authorship info is configured by editing /ubc/cs/project/arrow/git/authors. Authors not listed therein will be referred to in all logs by their UNIX username rather than their full name/email.

3. Import the repository to a temporary location, say ~/myrepo:

git cvsimport -i -a -v -C ~/myrepo -A /ubc/cs/project/arrow/git/authors PAPER

4. Create the remote repository (see next section)

5. Remove the temporary repository (unless you want to keep it as a local working repo)

rm -rf ~/myrepo

Creating a remote repository from an existing Git repository

(Taken from http://www.kernel.org/pub/software/scm/git/docs/gitcvs-migration.html)

We assume you have already created a git repository, for example by importing from CVS (above). Assume your existing Git repo is at ~/myrepo on a machine with UBC network access. Create a new "bare" repository and fetch your project into it:

$ mkdir /ubc/cs/project/arrow/git/myrepo
$ cd /ubc/cs/project/arrow/git/myrepo
$ git --bare init --shared
$ git --bare fetch ~/myrepo master:master
