* master: let VolumeList ask for the volumes it wants The request carried nothing, so every caller was answered with the whole cluster. A dashboard opening one volume's page, or a capacity probe adding up one bucket, was served all 800k of them and threw away the rest -- and the master built every one of those messages first. The topology, its disks and their counters are still reported in full: a caller reading free space or replica placement needs the cluster whichever volumes it asked about. Only what is listed under a disk is selected, ec shards included. An empty collection and a zero volume id take everything, the way volume.list already reads its own -collectionPattern and -volumeId, so a caller that forgets to narrow is answered too much rather than answered wrongly. That leaves the default collection unnameable, since it is the one the empty string names, so it gets a field of its own. An older client sends none of it and is answered exactly as before. * admin: ask the master for the volume the page is showing A volume's detail page was pulling every volume in the cluster to find one and its replicas, and discarding the rest. * admin: ask the master for the ec volume the page is showing Same as the volume detail page: one volume's shards were found by pulling every ec shard in the cluster. * s3: ask the master for the bucket's own collection The SOSAPI capacity probe summed one collection's volumes out of a listing of every volume in the cluster. Cluster capacity still comes out the same: it is read from the disk counters, which a filtered listing reports in full. * topology: read the disk usage counters atomically They are written with atomic.AddInt64 from heartbeats but were read plainly by the two listings and by FreeSpace, and the map they sit in was iterated without the lock its neighbour takes. Under -race a listing concurrent with a heartbeat trips on both.
