project management software

I am starting a software development project of 6 people, and I am looking for a configuration that will allow the following features:

• Create and assign tasks.


• Front end for source control


• Content managemen, e.g Wiki


• Notify user X when someone adds/updates/comments on a task that is assigned to X.


• Notify user X when someone updates a wiki page X is subscribed to (so there is an option to subscribe to Wiki pages)


• Can view a user list and see for each user what their tasks, commits, wiki entries.

It seems like Trac would come quite close, I am not sure if it allows viewing a user as mentioned and about notifications. I am also not sure if it is the best software available for these purposes.

Could you specify a software that would match these features as closely as possible?

Cheers!
