Source Code Indexing Service Analysis

Project Description

Mozilla’s source code is enormous—millions of lines of C, C++, JavaScript, Perl, Python, Java, C#, etc. Developers currently use the lxr system to quickly search and browse it on-line: http://lxr.mozilla.org. Mozilla is planning a move from CVS to Subversion for revision control, and at the same time wants to evaluate other source indexing services. Two BSD students are working to setup, document, and test other potential services (e.g., fisheye, opengrok, mxr) on one of the Seneca-Mozilla servers (see below). In each case this requires configuration changes and some scripting to get the services to properly integrate with Mozilla’s other on-line tools. When the test services are installed and synched with the live source tree, Mozilla will point its developers to them and get feedback—the students will help collect and synthesize this feedback.

Options

• Help with LXR/MXR/Bonsai development.
• Make a sort-of branch respectful version of OpenGrok
• [Re]write major portions of how OpenGrok deals with history and changesets and the likes, this is my personal preference.
• Try to fit Fisheye into the current development model, but it seems this might be more like finding a problem for a solution. That is not to say this is a very good tool!

Pulling CVS

This code will pull the CVS for the branches specified in @branches

use warnings;

# Pull CVS from the mozilla project server
my $src_root = "/var/mozilla";

# Where you want to you the HTML for the branch info
# This could be SSI'd, but that is a lot of work to set
# up with the ubuntu packages
my $branchlistpath = "${src_root}/branches.html";

# Where is your run.sh for opengrok? (or equivalent script to start the indexer)
my $opengroker = "/var/opengrok/run.sh";

# Where is your server?
my $cvsserver = ':pserver:anonymous@hera.senecac.on.ca:/cvsroot';

# Branches to be pulled
