Is there a way to run git gc --prune=now on remote Team Foundation Server 2015 (tfs2015)? Or is the only way to run git gc --prune=now locally then create new repository on tfs2015 and push it to new remote, then delete the old repository, and rename new repository to old name. Don't forget to turn off the liking commit when doing that.
Update about comming this in TFS v.Next And all ready rolled out in VSTS https://blogs.msdn.microsoft.com/congyiw/2015/12/14/why-does-cloning-from-vsts-return-old-unreferenced-objects/ "UPDATE (2017-08-09): We rolled out commit reachability bitmap indexes to VSTS and removed the clone cheat mentioned below. Cloning will no longer download unreachable objects!. We still don't have true object-level git gc on the server yet, but clone sizes will be smaller now.
TFS on-prem will get these changes in v.Next (not in any TFS 2017 updates, but the next major release). As Brian Harry mentioned, we should have a release candidate for v.Next in a few weeks."
