Setup bazaar over HTTP server

Setup bazaar over HTTP server

To setup bazaar over HTTP server use following steps:

1. Install mod_python package using 'yum -y install mod_python'. (Requires epel repository)
2. Create folder /var/www/scripts and download file media:Modpywsgi.py.txt in it.
3. Rename file using 'mv Modpywsgi.py.txt modpywsgi.py'
4. Assuming bazaar repository is configured in '/var/www/bzr' and branch named 'repo1' is configured using:

   cd /var/www
   bzr init-repo bzr
   cd bzr
   bzr init repo1
   cd /var/www
   chown -R apache:apache .

5. Configure basic download access using

   Alias /bzr /var/www/bzr
   <Directory /var/www/bzr>
   Options All
   AllowOverride all
   Order allow,deny
   Allow from all
   </Directory>

6. Use 'service httpd restart'
7. Try to access log using 'bzr log http://<server_ip_or_name>/bzr/repo1'
8. Configure smart access using:

   Alias /bzr /var/www/bzr
   <Directory /var/www/bzr>
   Options All
   AllowOverride all
   Order allow,deny
   Allow from all
   RewriteEngine On
   RewriteBase /bzr
   RewriteRule ^(.*/)?\.bzr/smart$ /scripts/bzr-smart.py
   </Directory>
   
   Alias /scripts/bzr-smart.py /var/www/scripts/bzr-smart.py
   <Directory /var/www/scripts>
   Options All
   AllowOverride all
   Order allow,deny
   Allow from all
   <Files bzr-smart.py>
   PythonPath "['/usr/lib64/python2.6/site-packages/bzrlib']+sys.path+['/srv/example.com/scripts']"
   AddHandler python-program .py
   PythonHandler bzr-smart::handler
   </Files>
   </Directory>

   Replace /bzr with repository name and /var/www/bzr with repository base folder appropriately at various places.

9. Create file named '/var/www/bzr-smart.py' with contents similar to:

   import modpywsgi
   from bzrlib.transport.http import wsgi
   
   smart_server_app = wsgi.make_app(
   root='/var/www/bzr',
   prefix='/bzr/',
   path_var='REQUEST_URI',
   readonly=False,
   load_plugins=True,
   enable_logging=True)
   
   def handler(request):
   """Handle a single request."""
   wsgi_server = modpywsgi.WSGIServer(smart_server_app)
   return wsgi_server.run(request)

   Replace /bzr with repository name and /var/www/bzr with repository base folder appropriately at various places.

10. Again use 'service httpd restart'
11. Do 'chown -R apache:apache /var/www/scripts'
12. Try to checkout repository using:

    bzr co bzr+http://<server_ip_or_name>/bzr/repo1

13. Or try to branch repository for decentralized usage using:

    bzr branch bzr+http://<server_ip_or_name>/bzr/repo1

14. Make changes to repository and try to commit.

Note that above setup of repository should be secured. It can be done by restricting access to web server through firewall or by enablng LDAP authentication as explained at Configuring LDAP based authentication for apache

Configuring LDAP based authentication for bazaar repository

Note that during authentication configuration, authentication needs to be enabled only for repository folder such as /bzr and not for scripts folder. Also line 'Allow from all' should be removed for authentication to take place.. For example, in above case part of configuration with authentication would look like:

    Alias /bzr /var/www/bzr
    <Directory /var/www/bzr>
    Options All
    AllowOverride all
    Order allow,deny
    RewriteEngine On
    RewriteBase /bzr
    RewriteRule ^(.*/)?\.bzr/smart$ /scripts/bzr-smart.py
    AuthType Basic
    AuthName "bzr bazaar repository"
    AuthBasicProvider ldap
    AuthzLDAPAuthoritative on
    AuthLDAPURL ldap://ldap.virtual-labs.ac.in:389/ou=people,dc=virtual-labs,dc=ac,dc=in?uid
    AuthLDAPGroupAttribute memberUid
    AuthLDAPGroupAttributeIsDN off
    Require ldap-group cn=admin,ou=groups,dc=virtual-labs,dc=ac,dc=in
    Require ldap-attribute gidNumber=501
    Satisfy any
    </Directory>
