Svn notes

Good start for basic subversion info is at https://help.ubuntu.com/community/Subversion

You may also want to read how to add a group or user to a group.

SVN client (GUIs)

Here is the list of my favorite clients for SVN

• Rapidsvn for version control and meld for comparing files

sudo apt-get install rapidsvn meld

• RabbitVCS - inspired by TortoiseSvn, but for Linux

Creating a basic SVN repository

Decide where your repository will be. Private could be under your home, public probably be somewhere else, e.g. at /var/lib/svn/ourproject/. This example creates a repository in /home/svn/myproject/.

sudo mkdir /home/svn
cd /home/svn
sudo mkdir myproject

sudo svnadmin create /home/svn/myproject

cd /home/svn
sudo chown -R www-data:subversion myproject
sudo chmod -R g+rws myproject

Global ignore

• Where to set the pattern for files to be ignored:

You can modify /etc/subversion/config like this

[miscellany]
global-ignores = *.class *.o tmp

• How to use a different username for a svn client (for example, rapidsvn)

SVN_SSH='ssh -l username' rapidsvn

Single unix account, multiple users access with public key authorization

Here is a description on how to set up svn on a single unix account and using private-public key authorization for multiple users.

• http://svn.collab.net/repos/svn/trunk/notes/ssh-tricks

In short: edit .ssh/authorized_keys file by adding lines as follows:

Consider

ssh-rsa AAAABlotsmoregookhere= address@example.com 

as "TYPE KEY COMMENT". Then add the following lines, one prer user:

 command="/path/to/svnserve -t -r /repository/root --tunnel-user=alice",no-port-forwarding,no-agent-forwarding,no-X11-forwarding,no-pty TYPE1 KEY1 COMMENT1
 command="/path/to/svnserve -t -r /repository/root --tunnel-user=bob",no-port-forwarding,no-agent-forwarding,no-X11-forwarding,no-pty TYPE2 KEY2 COMMENT2

Now you can have users authenticating the svn access with their private/public keys, using a single svn/unix account.

If you do not know how to generate the keys, here is how: Ssh_with_a_private-public_key

Integration with TRAC

You can make TRAC close messages when committing in svn by mentioning the ticket number like "This fixes #17". You will need to find (and install) the appropriate trac-post-commit-hook script for your TRAC version. Here is an example of the /var/svn/myproj/hooks/post-commit file:

#!/bin/sh
REPOS="$1"
REV="$2"
TRAC_ENV="/var/trac/mytrac"
MSG=$(svnlook log -r $REV /var/svn/myproj)
/usr/bin/python /usr/local/bin/trac-post-commit-hook -p "$TRAC_ENV" -r "$REV" -m $MSG
