LOGGERHEAD

==========

[ Version 1.6 for Bazaar 1.6 ]

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

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

Previous versions of Loggerhead read their configuration from a config

file.  This mode of operation is still supported by the

'start-loggerhead' script.  A 'loggerhead.conf.example' file is

included in the source which has comments explaining the various

options.

Loggerhead can then be started by running::

    $ ./start-loggerhead

This will run loggerhead in the background, listening on port 8080 by

default.

To stop Loggerhead, run::

    $ ./stop-loggerhead

In the configuration file you can configure projects, and branches per

project.  The idea is that you could be publishing several (possibly

unrelated) projects through the same loggerhead instance, and several

branches for the same project.  See the "loggerhead.conf.example" file

included with the source.

A debug and access log are stored in the logs/ folder, relative to

the location of the start-loggerhead script.

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'.

FILES CHANGED CACHE

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

To speed up the display of the changelog view for large trees,

loggerhead can be configured to cache the files changes between

revisions.  Set the 'cachepath' value in the config file.

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.
