Loggerhead:  A web viewer for ``bzr`` branches

==============================================

Loggerhead is a web viewer for projects in bazaar. It can be used to navigate 

a branch history, annotate files, view patches, perform searches, etc.

Loggerhead is heavily based on `bazaar-webserve

<https://launchpad.net/bzr-webserve>`_, which was, in turn, loosely

based on `hgweb <http://mercurial.selenic.com/wiki/HgWebDirStepByStep>`_.

Getting Started

---------------

Loggerhead depends on the following Python libraries.:

- SimpleTAL for templating.

- simplejson for producing JSON data.

- Paste for the server. (You need version 1.2 or newer of Paste.)

- Paste Deploy  (optional, needed when proxying through Apache)

- flup (optional, needed to use FastCGI, SCGI or AJP)

Installing Dependencies Using Ubuntu Packages

#############################################

.. code-block:: sh

   $ sudo apt-get install python-simpletal

   $ sudo apt-get install python-simplejson

   $ sudo apt-get install python-paste

   $ sudo apt-get install python-pastedeploy

   $ sudo apt-get install python-flup

Installing Dependencies Using :command:`easy_install`

#####################################################

.. code-block:: sh

   $ easy_install \

     -f http://www.owlfish.com/software/simpleTAL/py2compatible/download.html \

     SimpleTAL

   $ easy_install simplejson

   $ easy_install Paste

   $ easy_install PasteDeploy

   $ easy_install flup

Running the Standalone Loggerhead Server

----------------------------------------

After installing all the dependencies, you should be able to run

:command:`serve-branches` with the branch you want to serve on the

command line:

.. code-block:: sh

    ./serve-branches ~/path/to/branch

By default, the script listens on port 8080, so head to

http://localhost:8080/ in your browser to see the branch.

You can also pass a directory that contains branches to the script,

and it will serve a very simple directory listing at other pages.

You may update the Bazaar branches being viewed at any time.

Loggerhead will notice and refresh, and Bazaar uses its own branch

locking to prevent corruption.

See :doc:`serve-branches` for all command line options.

Running Loggerhead as a Daemon

------------------------------

To run Loggerhead as a linux daemon:

1) Copy the ``loggerheadd`` scipt to ``/etc/init.d``

.. code-block:: sh

   $ sudo cp ./loggerheadd /etc/init.d

2) Edit the file to configure where your Loggerhead is installed, and which

   serve-branches options you would like.

.. code-block:: sh

   $ sudo vim /etc/init.d/loggerheadd

3) Register the service

.. code-block:: sh

   # on upstart based systems like Ubuntu run: 

   $ sudo update-rc.d loggerheadd defaults

   # on Sysvinit based systems like Centos or SuSE run:

   $ sudo chkconfig --add loggerheadd

Using Loggerhead as a Bazaar Plugin

------------------------------------

This branch contains experimental support for using Loggerhead as a Bazaar

plugin.  To use it, place the top-level Loggerhead directory (the one

containing this file) at ``~/.bazaar/plugins/loggerhead``.  E.g.:

.. code-block:: sh

   $ bzr branch lp:loggerhead ~/.bazaar/plugins/loggerhead

   $ cd ~/myproject

   $ bzr serve --http

Using a Config File

-------------------

To hide branches from being displayed, add to ``~/.bazaar/locations.conf``,

under the branch's section:

.. code-block:: ini

    [/path/to/branch]

    http_serve = False

More configuration options to come soon.

Serving Loggerhead behind Apache

--------------------------------

If you want to view Bazaar branches from your existing Apache

installation, you'll need to configure Apache to proxy certain

requests to Loggerhead.  Adding lines like this to you Apache

configuration is one way to do this:

.. code-block:: apache

    <Location "/branches/">

        ProxyPass http://127.0.0.1:8080/branches/

        ProxyPassReverse http://127.0.0.1:8080/branches/

    </Location>

If Paste Deploy is installed, the :command:`serve-branches` script can be

run behind a proxy at the root of a site, but if you're running it at

some path into the site, you'll need to specify is using

``--prefix=/some_path``.

Search

------

Search is currently supported by using the bzr-search plugin (available

at: https://launchpad.net/bzr-search ).

You need to have the plugin installed and each branch indexed to allow

searching on branches.

Command-Line Reference

----------------------

.. toctree::

   :maxdepth: 2

   serve-branches

   start-loggerhead

   stop-loggerhead

Support

-------

Discussion should take place on the bazaar-dev mailing list at

mailto:bazaar@lists.canonical.com.  You can join the list at

<https://lists.ubuntu.com/mailman/listinfo/bazaar>.  You don't need to

subscribe to post, but your first post will be held briefly for manual

moderation.

Bugs are tracked on Launchpad; start at:

    https://bugs.launchpad.net/loggerhead

Hacking

-------

To run Loggerhead tests, you will need to install the package ``python-nose``,

and run its :command:`nosetests` script in the Loggerhead directory:

.. code-block:: sh

    nosetests

License

-------

GNU GPLv2 or later.
