doc/git-setup.txt

Some us are using git for managing quickly changing code. This file has
notes for setting that up.

ssh to robotics.mvla.net and add the git executables to your .bashrc:
  PATH=$PATH:/www/https/files/frc971/2013/brian/

[Cloning]
`git clone \
    ssh://USERNAME@robotics.mvla.net/www/https/git/frc971/SOMEBODY/2013.git`
  where USERNAME is your login on the server and SOMEBODY is whoever's git
  repo you want to clone
If you don't have a login on the server, then cloning
  https://robotics.mvla.net/git/frc971/somebody/2013.git instead should work
  (with your SVN username and password). However, that form of URL is read-
  only. In order for this to work, you have to either set the environment
  variable GIT_SSL_NO_VERIFY to 1 or set the git option http.sslverify to false.
  If you get an error like the one below, install a newer version of git.
    Unable to find 8fcd87533b76ca5b4b83fb6031ddf0de5e03eb57 under https://robotics.mvla.net/git/frc971/brian/2013.git
    Cannot obtain needed object 8fcd87533b76ca5b4b83fb6031ddf0de5e03eb57
    error: Fetch failed.
  I get this error sometimes with version 1.7.2.5 but not with version 1.7.10.4.

[Adding Other People's Repositories]
`git remote add SOMEBODY \
    ssh://USERNAME@robotics.mvla.net/www/https/git/frc971/SOMEBODY/2013.git`
  where USERNAME is your login on the server and SOMEBODY is another person's
  git repository
The https:// URL discussed above in [Cloning] will work too.

[Working with Other People's Repositories]
`git fetch SOMEBODY` will pull their changes, and then you can rebase on top of
  them etc.
`git push --mirror` will push all of your local branches so that everybody else
  can see them. (This is the default if the configuration option remote.<remote>.mirror is set.)
  However, you can not do that with an https:// URL.

[Synchronizing with SVN]
In order to synchronize the git commits with svn, somebody has to set up git-svn in their local git repo and then push/pull commits.

To do that, `git svn init https://robotics.mvla.net/svn/frc971/2013/trunk/src`

Then, unless you want git-svn to pull down everything from SVN again, you have to edit .git/refs/remotes/git-svn (or whatever you name the remote) in your local repository and put in the commit ID of the latest commit in the repository that's from SVN.

After doing that (and a `git svn fetch`), git-svn works like usual (see git-svn(1) for details).

To pull changes from svn, do `git-svn fetch`. To push changes to svn, do `git svn dcommit`, which will take all of your git commits between the latest commit from svn and your HEAD and make them into svn commits.

Multiple people dealing with svn works OK because the git commit SHAs end up the same so they all just become the same objects.

[Server Setup]
To get started working with git on the server, first you have to set up your
  .bashrc so that the git tools work. To do that, add the following line to your
  .bashrc *ABOVE* the '[ -z "$PS1" ] && return' line.
    PATH=$PATH:/www/https/files/frc971/2013/brian/
You also need a place to store your files. You will need an adminstrator to
  create a folder for you in /www/https/git/frc971 (on the server) with the
  correct permissions and group.

[Repository Setup]
To create a git repository on the server,
  "/www/https/git/frc971/brian/bare-git-repo" to wherever you want your
  repository (using `git init` won't work correctly). The standard location for
  mirrors of the "https://robotics.mvla.net/svn/frc971/YEAR/trunk/src" folder is
  "/www/https/git/frc971/USERNAME/YEAR.git".
In order for https:// access to work, you have to make sure to rename
  .git/hooks/post-update.sample to .git/hooks/post-update (and then run
  `git update-server-info` if you're not going to push immediately).

To learn more about git, see git(1) (`man git` or
  <http://manpages.debian.net/cgi-bin/man.cgi?query=git>) (especially the NOTES
  section).
