Projects::ForkService delegates to this service almost entirely, but needed
one small change so it would propagate create errors correctly.
CreateService#execute needs significant refactoring; it is now right at the
complexity limit set by Rubocop. I avoided doing so in this commit to keep the
diff as small as possible.
Several tests depend on the insecure behaviour of ForkService, so fi them up at
the same time.
Browser interface allows forking to an owned grup.
This commit brings API up to speed by providing optional namespace
parameter to fork API. This allows forking to users and groups under
forker's control using their id or unique name.
Fixes#21591
This change adds POST /projects/fork/:id to the API for forking
a project into the namespace of the authenticated user, like the
"create fork" link in the GUI does. It also calls the same code.
Failure and permission checks (except for conflict) are already
implemented and handled in ForkService and the API, so the added
code is simple and does not alter anything.
