ITK version tracking and development is hosted by [http://git-scm.com Git].
 
=Official Repository=
 
One may browse the repository online using the [http://git.wiki.kernel.org/index.php/Gitweb Gitweb] interface at http://itk.org/gitweb.
 
==Cloning==
 
Clone ITK using the command
 
$ git clone --recursive git://itk.org/ITK.git
 
This requires Git 1.6.5 or higher.  If you do not have it, see [[#Git Below 1.6.5|below]].
If your institution's firewall blocks the Git port for outgoing connections, see [[#Firewall_Blocks_Port_9418|below]].
If you do '''not''' want to run tests, leave off the <code>--recursive</code> option to avoid downloading the <code>Testing/Data</code> submodule.
 
All further commands work inside the local copy of the repository created by the clone:
 
$ cd ITK
 
For ITKApps, use the url
 
git://itk.org/ITKApps.git
 
instead.
 
==Branches==
 
At the time of this writing the repository has the following branches:
 
* '''master''': Development (default)
* '''nightly-master''': Follows '''master''', updated at 01:00 UTC
* '''hooks''': Local commit hooks ([[Git/Hooks#Local|place]] in .git/hooks)
* '''dashboard''': Dashboard script (see [[#Dashboard|below]])
 
Release branches converted from CVS have been artificially merged into master.
Actual releases have tags named by the release version number.
 
=Development=
 
We provide here a brief introduction to '''ITK''' development with Git.
See the [[Git/Resources|Resources]] page for further information such as Git tutorials.


==Introduction==
==Introduction==


We require all commits in ITK to record valid author/committer name and email information.
ITK version tracking and development is hosted by [http://git-scm.com Git].
Use [http://www.kernel.org/pub/software/scm/git/docs/git-config.html git config] to introduce yourself to Git:
Please select a task for further instructions:


$ git config --global user.name "Your Name"
{|border="0"
$ git config --global user.email "you@yourdomain.com"
|-
 
|width=70%|
Note that "Your Name" is your ''real name'' (e.g. "John Doe", not "jdoe").
Main Tasks:
While you're at it, optionally enable color output from Git commands:
 
$ git config --global color.ui auto
 
If less displays strange characters and no color, your LESS environment variable may already be set. You can override the less options with:
 
$ git config --global core.pager "less -FXRS"
 
The <code>--global</code> option stores the configuration settings in <code>~/.gitconfig</code> in your home directory so that they apply to all repositories.
 
==Hooks==
 
The '''hooks''' branch provides local commit hooks to be placed in <code>.git/hooks</code>.
It is shared by many <code>public.kitware.com</code> repositories.
 
See the general [[Git/Hooks|hooks]] information page to set up your local hooks.
 
==Workflow==
 
We've chosen to approximate our previous CVS-based development workflow after the initial move to Git, at least while things get settled.
The basic rule is to rebase your work on origin/master before pushing:
 
git fetch origin
git rebase origin/master
 
or
 
git pull --rebase
 
The server will refuse your push if it contains any merges.
Later we will move to a full [[Git/Workflow/Topic|branchy workflow]] based on topic branches.
 
==Topic Stage==
 
We provide a "[http://itk.org/stage/ITK.git ITK Topic Stage]" repository to which developers may publish arbitrary topic branches and request automatic merges.
 
The topic stage URLs are
 
* <code>git://itk.org/stage/ITK.git</code> (clone, fetch)
* <code>http://itk.org/stage/ITK.git</code> (clone, fetch, gitweb)
* <code>git@itk.org:stage/ITK.git</code> (push)
 
See our [http://public.kitware.com/Wiki/Git/Workflow/Stage Topic Stage Workflow] documentation for general instructions.
''(Currently ITK does not have a '''next''' branch.  Just skip that part of the instructions and merge directly to master.)''
When accessing the ITK stage, one may optionally substitute
"<code>ssh git@itk.org stage ITK ...</code>"
for
"<code>ssh git@public.kitware.com stage <repo> ...</code>"
in the ssh command-line interface.

|}


Note that the stage implementation is not ITK-specific and is used for other projects too.
''The remainder of this page provides reference information and links.  It is not intended to provide instructions.''
If the merge attempt conflicts it may print instructions for performing the merge manually.
'''Ignore''' these instructions; you will not be able to push the merge commit directly.
Instead, identify the commit that conflicts with yours, merge it into your topic locally, push the topic to the stage again, and then repeat the merge request.

==Repositories==


==Pushing==
One may browse the repositories online using the [https://git.wiki.kernel.org/index.php/Gitweb Gitweb] interface at http://itk.org/gitweb.


Authorized developers may publish work directly to <code>itk.org/ITK.git</code> using Git's SSH protocol.

See the [[Git/Publish#Push_Access|push instructions]] for details.
==Branches==


For ITK, configure the push URL:
At the time of this writing the <code>ITK.git</code> repository has the following branches:


git config remote.origin.pushurl git@itk.org:ITK.git
* '''master''': Development (default)
* '''release''': Maintenance of latest release
* '''release-3.20''': Maintenance of the ITKv3 series
* '''nightly-master''': Follows '''master''', updated at 01:00 UTC
* '''hooks''': Local commit hooks ([[Git/Hooks#Local|place]] in .git/hooks)
* '''dashboard''': Dashboard script ([[ITK/Git/Dashboard|setup]] a CDash client)


For ITKApps, configure the push URL:
Release branches converted from CVS have been artificially merged into master.
 
Actual releases have tags named by the release version number.
git config remote.origin.pushurl git@itk.org:ITKApps.git
 
===Update Hook===
 
The itk.org repository has an <code>update</code> hook.
When someone tries to push changes to the repository it checks the commits as documented [[Git/Hooks#update|here]].
 
=Testing=
 
==Dashboard==
 
The [[#Branches| dashboard]] branch contains a dashboard client helper script.
Use these commands to track it:
 
$ mkdir -p ~/Dashboards/ITKScripts
$ cd ~/Dashboards/ITKScripts
$ git init
$ git remote add -t dashboard origin git://itk.org/ITK.git
$ git pull origin
 
The <code>itk_common.cmake</code> script contains setup instructions in its top comments.
Update the '''dashboard''' branch to get the latest version of this script by simply running
 
$ git pull origin
 
=Troubleshooting=
 
==Firewall Blocks Port 9418==
 
Some institutions have firewalls that block Git's native protocol port 9418.
Use the "<code>url.<base>.insteadOf</code>" configuration option to map git URLs to http:
 
<pre>
$ git config --global url.http://itk.org/.insteadOf git://itk.org/
</pre>
 
This tells Git to translate URLs under the hood by replacing prefixes.
After running these commands ''once'' in your home directory then you can just use the "<code>git://</code>" mentioned elsewhere on this page and git will use the http protocol automagically.
 
==Git Below 1.6.5==
 
To clone ITK using Git 1.6.4 or lower, use the commands
 
$ git clone git://itk.org/ITK.git
$ cd ITK
$ git submodule init
$ git submodule update
 
=Resources=
