RabbitVCS

Ubuntu 12.04

sudo add-apt-repository ppa:rabbitvcs/ppa
sudo apt-get update && sudo apt-get install rabbitvcs-nautilus rabbitvcs-cli  rabbitvcs-gedit

Ubuntu 13.10

PROBLEM, please read teh next, install testing ppa and nautilus3-version! 

sudo add-apt-repository ppa:rabbitvcs/rabbitvcs-testing
sudo apt-get update && sudo apt-get install rabbitvcs-nautilus rabbitvcs-nautilus3 rabbitvcs-cli rabbitvcs-gedit

SVN Integration with https

This HowTo is tested with Debian 6 (squeeze) but should be applicable to any Linux based distribution.

First of all your repository, e.g. /home/svn must be writable by the webserver: 

MYREPO="/home/svn"
chown -R www-data:www-data ${MYREPO}
find ${MYREPO} -type d -exec chmod 2755 \{} \;
find ${MYREPO} -not -type d -exec chmod 0644 \{} \;

Then you need mod_dav for apache2: 

apt-get install libapache2-svn
a2enmod dav
a2enmod dav_svn


To access an svn like https://serverip/svn/repo1 (with read/write access for user1) https://serverip/svn/repo2 (with read/write access for user2) 

/path/to/
      └── svn
           ├── repo1  -> should only be rw-accessible by user1
           └── repo2  -> should only be rw-accessible by user2

do the following 3 (4) steps:

First: create a dav configuration file

cd /etc/apache2/mods-available/
vim dav_svn.conf

<Location /svn>
    DAV svn
    SVNParentPath /path/to/svn
    AuthType Basic
    AuthName "Subversion Repository"
    AuthUserFile /etc/apache2/dav_svn.passwd
    AuthzSVNAccessFile /etc/apache2/dav_svn.authz
     
    # Allow access only with authentification
    Require valid-user
  
    # Allow acces with anonymous checkout
    #<LimitExcept GET PROPFIND OPTIONS REPORT>
    #  Require valid-user
    #</LimitExcept>
  
</Location>

Second: set passwords for users:

For the first user call htpasswd with the -c parameter (this _c_reates a new file and - of course - overwrites an existing one!): 

htpasswd -c /etc/apache2/dav_svn.passwd  user1

and for every one after that without “-c“ (because this in case will overwrite the file!!!) 

htpasswd /etc/apache2/dav_svn.passwd  user2

Third: create the authz file for authorization:

vim /etc/apache2/dav_svn.authz

## groups or users
#groupname = user1,user2

## repositories
## the repositoryname is relative (!) to the given
## repository in the dav_svn.conf file

#[reponame:/]
## read / write access for all users
#* = rw 
## nor read acces for this group
#@groupname = 
## read access for this user
#user1 = r

#[reponame:/trunk/]
## read / write access for user1 to /trunk/
#user1 = rw

[repo1:/]
user1 = rw

[repo2:/]
user2 = rw

Create a virtual host if you like:

SERVERIP="1.2.3.4"
MAIL="webmaster@mydomain.com"
DOMAIN="svn.example.com"
DOCPATH="/var/www"
SSLPATH="/var/webs/ssl"
CUSTOMER=""
CHAINFILE="/var/webs/ssl/CAcert_chain.pem"

cat << EOF > ${DOMAIN}.conf
<VirtualHost ${SERVERIP}:443>
  ServerAdmin webmaster@${DOMAIN}
  ServerName  www.${DOMAIN}
  ServerAlias ${DOMAIN}

  DocumentRoot ${DOCPATH}
  <Directory ${DOCPATH}>
    Options -MultiViews
    allow from all
  </Directory>
  # Possible values include: debug, info, notice, warn, error, crit,
  # alert, emerg.
  LogLevel warn

  CustomLog /var/log/apache2/access.log combined
  ErrorLog /var/log/apache2/error.log

  SSLEngine on
  SSLCertificateFile ${SSLPATH}/${CUSTOMER}/${DOMAIN}.cert
  SSLCertificateKeyFile ${SSLPATH}/${CUSTOMER}/${DOMAIN}.key
  SSLCertificateChainFile ${CHAINFILE}

</VirtualHost>
EOF

Restart Apache: 

/etc/init.d/apache2 restart

svn+ssh and https together

  • Already running an ssh server?
  • Already have a user with ssh account (that's necessary)
  • BUT: this assumes that a users are in the subversion group and therefore have access to each other!!!
  • THAT'S WHY: for systems with greater user count use the https method!

Add the user you want to add to the subversion group: 

adduser username subversion
(or later remove with: deluser username subversion)

Alter permissions of the repository "users_repository" 

chown /home/svn www-data:subversion
chmod 770 /home/svn
cd /home/svn
chown -R www-data:subversion users_repository
find users_repository/. -type d -name "*" -exec chmod -R g+rws {} \;
find users_repository/. -type f -name "*" -exec chmod -R g+rw {} \;

That's it.

Now you can connect e.g.: 

svn checkout svn+ssh://username@SERVER_IP/home/svn/users_repository

Attention: In your checked out repository you have to switch the svn access url from http to svn+ssh! 

svn switch --relocate http://domain.com/{repo} svn+ssh://{username}@domain.com/home/{username}/svn/{repo}

svnsync

Taken from:

Create the following variables: 

MYPATH="/home/svn"
URL_TO_REPO_ROOT_TO_CLONE="https://axelpospischil@ssl.qwws.net/svn/mt_roadrunner"
DEST_URL="/home/svn"

(Note: „DEST_URL“ is the url to the Subversion repository you create in step 1.)

1. Create your local repository: 

svnadmin create ${MYPATH}

2. Create an empty pre-revprop-change hook script: 

echo '#!/bin/bash' > ${MYPATH}/hooks/pre-revprop-change

3. Make the pre-revprop-change hook script executable: 

chmod +x ${MYPATH}/hooks/pre-revprop-change

4. Initialize svnsync: 

svnsync init file:⁄⁄⁄${MYPATH} ${URL_TO_REPO_ROOT_TO_CLONE}

5. Synchronize: 

svnsync sync ${DEST_URL}

Subversion 1.6.x needs those added to the pre-revprop-change script: 

    REPOS="$1"
    REV="$2"
    USER="$3"
    PROPNAME="$4"
    ACTION="$5"

Einrichten unter Debian

1. Svn installieren: 

apt-get update
apt-get install subversion

2. Eine svn Gruppe erstellen und einen Benutzer hinzufügen: 

groupadd subversion
addgroup username subversion

3. Ein svn Repository erzeugen oder ein Vorhandenes kopieren 

mkdir /home/svn/myrepo
rsync -av oldserver:/home/svn /home/.
chown -R root:subversion /home/svn
svnadmin create --fs-type fsfs /home/svn/myrepo/projekt1
svnadmin create --fs-type fsfs /home/svn/myrepo/projekt2

4. Einloggen via ssh (geht nur, wenn ein ssh-Schlüssel im Userverzeichnis generiert wurde) 

ssh+svn://servername/home/svn/myrepo


svn ppa

Probably you are working in mixed environments.

The ubuntu svn repository always gives you access to the most actual subversion files:

svn upgrade

Be careful with this an first make a backup of your working directory!

Sometimes it could be necessary to update an svn tree to use with a newer svn version. E.g. you have an archive of subversion 1.6, copied it over to your system whitch is running subserversion 1.7. 

cd YOUR_PROJECTS_DIR
find . -name .svn | awk '{system("cd " $0 "; cd .. ; svn upgrade")}'

svn cleanup

find . -name .svn | awk '{system("cd " $0 "; svn cleanup")}'
