This document describes one way to set up a Bazaar HTTP smart server,

using Apache 2.0 and FastCGI or mod_python or mod_wsgi.

You have a webserver already publishing `/srv/example.com/www/code` as
16
20
`http://example.com/code/...` with plain HTTP. It contains bzr branches and

LoadModule fastcgi_module /usr/lib/apache2/modules/mod_fastcgi.so

In our example, we're already serving `/srv/example.com/www/code` at
35
39
`http://example.com/code`, so our existing Apache configuration would look

This instructs Apache to hand requests for any URL ending with `/.bzr/smart`
103
107
inside `/code` to a Bazaar smart server via mod_python.
105
NOTE: If you don't have bzrlib in your PATH, you will be need to change the
108
PythonPath "sys.path+['/srv/example.com/scripts']"
112
PythonPath "['/path/to/bzr']+sys.path+['/srv/example.com/scripts']"

Refer to the mod_python_ documentation for further information.

.. _mod_python: http://www.modpython.org/
123
First, configure mod_wsgi, e.g. enabling the mod with a2enmod wsgi.
124
We need to change it to handle all requests for URLs ending in `.bzr/smart`. It

WSGIScriptAliasMatch ^/code/.*/\.bzr/smart$ /srv/example.com/scripts/bzr.wsgi

#The three next lines allow regular GETs to work too

This instructs Apache to hand requests for any URL ending with `/.bzr/smart`
139
inside `/code` to a Bazaar smart server via WSGI, and any other URL inside
140
`/code` to be served directly by Apache.

The `fcgi` module can be found at http://svn.saddi.com/py-lib/trunk/fcgi.py. It

is part of flup_.

return wsgi_server.run(request)
199
The `modpywsgi` module can be found at
200
http://ice.usq.edu.au/svn/ice/trunk/apps/ice-server/modpywsgi.py. It was
201
part of pocoo_. You sould make sure you place modpywsgi.py in the same
202
directory as bzr-smart.py (ie. /srv/example.com/scripts/).
204
.. _pocoo: http://dev.pocoo.org/projects/pocoo/
210
We've configured Apache to run the smart server at
211
`/srv/example.com/scripts/bzr.wsgi`. This is just a simple script we need
212
to write to configure a smart server, and glue it to the WSGI gateway.
213
Here's what it looks like::
215
from bzrlib.transport.http import wsgi
217
def application(environ, start_response):
219
root="/srv/example.com/www/code/",
222
enable_logging=False)

return app(environ, start_response)

Pushing over the http smart server
264
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
207
Pushing over ``bzr+http://``
208
----------------------------
266
210
It is possible to allow pushing data over the http smart server. The
267
211
easiest way to do this, is to just supply ``readonly=False`` to the
268
212
``wsgi.make_app()`` call. But be careful, because the smart protocol does
269
213
not contain any Authentication. So if you enable write support, you will
270
214
want to restrict access to ``.bzr/smart`` URLs to restrict who can
271
actually write data on your system, e.g. in apache it looks like::
276
AuthUserFile /srv/example.com/conf/auth.passwd
282
At this time, it is not possible to allow some people to have read-only
283
access and others to have read-write access to the same urls. Because at
284
the HTTP layer (which is doing the Authenticating), everything is just a
285
POST request. However, it would certainly be possible to have HTTPS
286
require authentication and use a writable server, and plain HTTP allow
289
If bzr gives an error like this when accessing your HTTPS site::
291
bzr: ERROR: Connection error: curl connection error (server certificate verification failed.
292
CAfile:/etc/ssl/certs/ca-certificates.crt CRLfile: none)
294
You can workaround it by using ``https+urllib`` rather than ``http`` in your
295
URL, or by uninstalling pycurl. See `bug 82086`_ for more details.
