| Some of 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). |
| |

| <http://manpages.debian.net/cgi-bin/man.cgi?query=git>) (especially the NOTES |
| section). |
