Project management tools/2010 Review

It is time to evaluate whether Bugzilla meets our requirements as a bug tracker or whether a different tool would suit us better. Our basic requirements are bug tracking, feature tracking and project management.

Tracker Requirements

 * VCS integration. Ability to associate to revisions.
 * Currently, this means SVN, but it could mean some other VCS in the future.
 * Ability to import data from existing Bugzilla instance.
 * Not a show-stopper necessarily. Bugzilla could be closed to new bugs and we use both until things in Bugzilla are fixed or migrated. Would want very strong consensus to go this route though.
 * Ability to manage different projects.
 * Free (Beer and Speech)
 * Separation between "tasks" (as a way to track task progress) and other items such as:
 * Bugs
 * Feature requests
 * Would be great to have finer-grained email subscription options: for example, simple committers might be uninterested in site requests.

Project Management Tools requirements
Required:
 * web-based (for collaboration)
 * multi-project
 * calendar/scheduling
 * assignments & resource management
 * time tracking per task/user/project

Nice to have:
 * Gantt chart
 * Public/private projects
 * Fine-grained access to projects by user
 * Basic accounting & budget management
 * Requirements management

Possible Solutions
Leading candidates:
 * Bugzilla - we can stick with Bugzilla, perhaps tricking it out with some new extensions. The version of Bugzilla we're on now is much more current (3.4.5) than what had been up a few months ago.  The latest version has a new extension system that potentially makes it so that it can be extended.  As Bugzilla is currently configured, it doesn't do what we'd like.
 * Redmine - Out of the box, it looks like Redmine does what we want. (possibly with the RequMNGT and RiskMNGT plugins; see full list of plugins)

Other possibilities:
 * Trac (see plugins etc.)
 * Google IssueTracker, or the GPL clone Indefero
 * JIRA (Free for open source and non-profit organizations, but not open source and not free generally)
 * "Extended" MediaWiki &mdash; Some features like SVN-Integration is already done with Special:Code/MediaWiki so maybe with help of some extension like Semantic MediaWiki and some additional extensions, mediawiki could meet the given requirements
 * See Helpdesk system and datacenter inventory Semantic MediaWiki prototypes added to my prototype wiki and prototype
 * See CcTeamspace, a working implementation of this idea used by the Creative Commons organization
 * Launchpad
 * Project Net
 * OBM
 * Mantis
 * Eventum
 * Gerrit Code Review tool for Git

Things to think about if we go forward

 * How to organize products, projects, subprojects, etc.
 * How to manage obsolete products (e.g. obsolete extensions, see )
