LOGGERHEAD

==========

[ Version 1.17 for Bazaar 1.17 ]

Loggerhead is a web viewer for Bazaar branches.  It can be used to

navigate a branch history, annotate files, perform searches... all the

usual things.

GETTING STARTED

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

Loggerhead depends on:

1) SimpleTAL for templating.

   On Ubuntu, `sudo apt-get install python-simpletal`

   or download from http://www.owlfish.com/software/simpleTAL/download.html

2) simplejson for producing JSON data.

   On Ubuntu, `sudo apt-get install python-simplejson`

   or use `easy_install simplejson`.

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

   On Ubuntu, `sudo apt-get install python-paste`

   or use `easy_install Paste`

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

   On Ubuntu, `sudo apt-get install python-pastedeploy`

   or use `easy_install PasteDeploy`

Then simply run the 'serve-branches' with the branch you want to

serve on the command line:

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

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.

To run loggerhead as a linux daemon: 

1) Copy loggerheadd to /etc/init.d

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

   serve-branches options you would like.

3) Register the service

   cd /etc/init.d

   a) on upstart based systems like Ubuntu run: 

      update-rc.d loggerheadd defaults

   b) on Sysvinit based systems like Centos or SuSE run:

      chkconfig --add loggerheadd

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``.

USING A CONFIG FILE

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

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

under the branch's section:

    [/path/to/branch]

    http_serve = False

More configuration options to come soon.

SERVING LOGGERHEAD FROM 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::

    <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 '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.

SUPPORT

-------

Loggerhead is loosely based on bazaar-webserve, which was loosely

based on hgweb.  Discussion should take place on the bazaar-dev

mailing list at 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.
