Anonymous GNUstep SVN Checkout
You cannot use SVN+SSH unless you are a developer, and have a username and SSH public key registered at gna.org. See below for more details. You cannot check out /devmodules unless you are a developer. /modules is the same as /devmodules, except the SVN external references work for anonymous SVN checkouts.
Developer GNUstep SVN Checkout
svn co svn+ssh://svn.gna.org/svn/gnustep/devmodules
Setting up Subversion for Developer Use
The first thing you will want to do is setup the ssh access to svn.gna.org. If you cannot type
svn list svn+ssh://svn.gna.org/svn/gnustep/devmodules
without having to type a password or in some way change the above command, read below.
If you have a different username on your system than on svn.gna.org
To get around this problem, you can setup per host SSH settings. To do this, open ~/.ssh/config and at the end add the lines
Host svn.gna.org User aeruder
This makes it so that everytime I connect to svn.gna.org with SSH, it will automatically use the username aeruder instead of my unix username.
If you are prompted for a private key password
This will look something like:
Enter passphrase for key '/home/andy/.ssh/id_dsa':
To get around this you can either setup ssh-agent to cache this password or you can simply turn off the password on your private key. To do the latter, simply type:
ssh-keygen -t dsa -p
and follow the prompts, and when it prompts for a new passphrase, simply hit enter.
Some background on repository layout
To familiarize yourself with the layout, I would recommend looking at the web-access to svn for GNUstep. You will notice that every project is in its own portion of the repository. For example:
/libs /libs/gui /libs/gui/trunk /libs/gui/branches /libs/gui/branches/dawn /libs/gui/branches/... /libs/gui/tags /libs/gui/tags/alex_last_semistable /libs/gui/tags/...
This layout is very handy for having a per-project repository. I can easily branch or tag just /libs/gui and it all stays in its own namespace. However, what this DOES mean is that you cannot simply checkout /libs/gui or you will end up with several copies of the source. To get around this, we are using a nifty feature of Subversion called externals. Externals are metadata on a directory that basically tell the svn client to checkout some other url into a subdirectory when it is checked out. So if I type:
svn proplist -v svn+ssh://svn.gna.org/svn/gnustep/devmodules/core
It will tell me that the svn:externals property contains:
gui svn+ssh://svn.gna.org/svn/gnustep/libs/gui/trunk back svn+ssh://svn.gna.org/svn/gnustep/libs/back/trunk base svn+ssh://svn.gna.org/svn/gnustep/libs/base/trunk make svn+ssh://svn.gna.org/svn/gnustep/tools/make/trunk
So everytime I checkout /devmodules/core the svn client will automatically go to these URLs and check them out into subdirectories. When I make changes in gui/ and commit them, it will really commit to /libs/gui/trunk. For the most part if you checkout /devmodules, the externals have already been setup such that it will checkout something similar to checking out the whole repository before.
Tips, Tricks, and Resources
- Version Control with Subversion
- Appendix A: Subversion for CVS Users
- GCC's SVN Setup page - Look especially at the section on ssh connection caching.
- Subversion_Migration - Some initial notes on the layout of the repository.
- ZSH svn tab completion - On this page is a tab completion module that can tab complete into subversion repositories. Very handy for ZSH users.
