History of git

{maketoc}bitweaver is attempting to complete our ((CVS Migration)) to the [http://git-scm.com/|git] version control system. We have broken our CVS virtual modules in 150+ individual git repositories.

!Gitting Started

Here are the steps to git up to speed and begin developing bitweaver on git:

!!1. Get some Git.
There are [http://git-scm.com/download|downloads for all major platforms] however, be aware the anything other than the command line on linux is temperamental. Additional notes for using git with windows are being ((git on windows|developed here)).

!!2. Register on [http://github.com]
Let us know on ((IRC)) so we can add you as a collaborator. (BW Admins, there is a script to make this process simpler //WILL - PLEASE PUT SCRIPT SOMEPLACE ON MODELA//

!!3. Clone and Go
Since bitweaver is completely modular, the bitweaver.git clone master repository is simply a collection of submodules for each of the packages.

For standard read-only access, use:
{code source=bash}git clone git://github.com/bitweaver/bitweaver.git -b READONLY{/code}
If you are a developer and need commit access, use:
{code source=bash}git clone git@github.com:bitweaver/bitweaver.git{/code}
This will create a 'bitweaver' directory where you are. Follow up with...
{code source=bash}
cd bitweaver
git submodule update --init
git submodule foreach --recursive git submodule update --init
git submodule foreach --recursive git checkout master
That will pull down all of the sub repositories for the directory structure the first clone created.
//style and icon sections need to be redirected to the correct subfolders//

!!! Create your own bitweaver distro
If you have a custom set of modules, you can create your own master project. Here are the instructions:
{code source=bash}mkdir newproject
cd newproject
git init
# add the core set of packages for a minimal bitweaver install
for PACKAGE in kernel languages liberty storage themes users util wiki install; do git submodule add git@github.com:bitweaver/$PACKAGE.git; done
# initialize all nested submodules (mostly in util)
git submodule foreach --recursive git submodule update --init
# Create a root level index.php , copy from https://github.com/bitweaver/bitweaver/blob/master/index.php
wget https://raw.github.com/bitweaver/bitweaver/master/index.php
# setup your own local config package, which typically is included in your master project git repo
mkdir config config/kernel/ config/themes config/icons
# Create a config bit_setup_inc.php , copy from https://github.com/bitweaver/config/blob/master/bit_setup_inc.php
cd config
wget https://raw.github.com/bitweaver/config/master/bit_setup_inc.php
cd ..
git add config index.php
git commit -m "initialize super project" -a
git submodule foreach --recursive git submodule update --init
mkdir temp; chmod 777 temp
# add some icons and themes
git submodule add git@github.com:bitweaver/iconset_tango.git config/icons/tango
git submodule add git@github.com:bitweaver/theme_basic.git config/themes/basic

!Creating a new Repository
Contact a bitweaver admin to [http://help.github.com/creating-a-repo/|create a new repo on github] for you.

!Repository Locations

We are going to attempt to keep our code on github. There are is one major problem with Github currently - [http://support.github.com/discussions/post-receive-issues/106-cia-hook-has-no-project-options-fear|the lack of decent IRC notification].

We have a backup plan if github does not work out. We have our own install running gitosis, which was set up by [/nickpalmer]
Contact an admin via ((IRC)) about getting a public key added. If github continues to suck, we will revert to bitweaver.org which is running gitosis, and we can mirror push'es to github on an update hook.

!Import concepts in Git

This is the __second major stumbling block__. Git submodules are similar to virtual modules in CVS. The achilles heal of git submodules is a "git submodule add ..." is tied to a particular commit for the submodule repository.

A lesser issue, submodules can only have directories in the current directory, so you have to nest. We cannot do the all-in-one "cvs co bitewaver" like we used to.
