Pagure offers the possibility to flag pull-requests
and commits. A flag is a way for a third-party tool
to provide feedback on a pull-request or a commit.
Two settings above allow notifying contributors and
watchers of a project when new flags are being added.
The flags documentation.
Pagure supports leaving the issue tracker activated but making it read-only, thus letting people access to the existing tickets without allowing creating new tickets or comments.
Pagure supports blocking direct commit access to a project and enforcing all changes to a project to be done via pull-requests.
Pagure supports making the roadmap page the front page of the issue list.
Lets pagure send fedmsg notification for all actions
performed in a project (new ticket, new pull-request,
new comment...).
Sending fedmsg notifications upon commits is performed
via a git hook though, see the Hooks section in this
settings page.
