Empty map transcript

1. Setup: make a new, empty map.

$ grpc_cli -loas2=false call localhost:6962 trillian.TrillianAdmin.CreateTree \
  'tree<tree_state: ACTIVE tree_type: MAP hash_strategy: TEST_MAP_HASHER hash_algorithm: SHA256 \
   signature_algorithm: ECDSA max_root_duration<seconds: 3600>> key_spec<ecdsa_params<curve: P256>>'

tree_id: 6052818873547722634
tree_state: ACTIVE
tree_type: MAP
hash_strategy: TEST_MAP_HASHER
hash_algorithm: SHA256

public_key {
  der: "0Y0\023\006\007*\206H\316=\002\001\006\010*\206H\316=\003\001\007\003B\000\004\0173\026;\315\255\367\325\252\31791\2158S2\271\177\307\377=\210!\022[\356\347\233\251Vf\026FR\217P\256\355,\347\330h\000\316qL\342\373:\370\214\016\204\007\334\001\233\302\031\207\305\254[\000"

}


2. Try to retrieve the map root, specifying revision 0

$ grpc_cli -loas2=false call localhost:6962 trillian.TrillianMap.GetSignedMapRootByRevision \
  'map_id:6052818873547722634'

Rpc failed with status code 5, error message: sql: no rows in result set


3. Try to retrieve the latest map root

$ grpc_cli -loas2=false call localhost:6962 trillian.TrillianMap.GetSignedMapRoot \
  'map_id:6052818873547722634'

map_root {
}


4. Try to retrieve map root specifying some other revision numbers; -1 (which means 'latest' in GetLeaves); 1.

$ grpc_cli -loas2=false call localhost:6962 trillian.TrillianMap.GetSignedMapRootByRevision \
  'map_id:6052818873547722634 revision:-1'

Rpc failed with status code 5, error message: sql: no rows in result set


$ grpc_cli -loas2=false call localhost:6962 trillian.TrillianMap.GetSignedMapRootByRevision \
  'map_id:6052818873547722634 revision:0'

Rpc failed with status code 5, error message: sql: no rows in result set


$ grpc_cli -loas2=false call localhost:6962 trillian.TrillianMap.GetSignedMapRootByRevision \
  'map_id:6052818873547722634 revision:1'

Rpc failed with status code 5, error message: sql: no rows in result set


5. Now set some leaf values to force a new map head.
   - TODO: confirm that this minimal call is OK - we don't actually specify any leaves here...

$ grpc_cli -loas2=false call localhost:6962 trillian.TrillianMap.SetLeaves \
  'map_id:6052818873547722634'

map_root {

  }
  map_id: 6052818873547722634
  map_revision: 1
}


6. OK now retrieve the Map Head at revision 1 via both APIs.
$ grpc_cli -loas2=false call localhost:6962 trillian.TrillianMap.GetSignedMapRoot \
  'map_id:6052818873547722634'

map_root {

  root_hash: "\306h\237\020\201*\t\200\227m\2253\3308u(!f\025\225g\3545\025W\026\301A:\365=j"
  signature {

    signature_algorithm: ECDSA

  }
  map_id: 6052818873547722634
  map_revision: 1
}


$ grpc_cli -loas2=false call localhost:6962 trillian.TrillianMap.GetSignedMapRootByRevision \
  'map_id:6052818873547722634 revision:1'

  }
  map_id: 6052818873547722634
  map_revision: 1
}


7. Confirm that revisions 0 and -1 are _still_ not retrievable
$ grpc_cli -loas2=false call localhost:6962 trillian.TrillianMap.GetSignedMapRootByRevision \
  'map_id:6052818873547722634 revision:0'

Rpc failed with status code 5, error message: sql: no rows in result set


$ grpc_cli -loas2=false call localhost:6962 trillian.TrillianMap.GetSignedMapRootByRevision \
  'map_id:6052818873547722634 revision:-1'

Rpc failed with status code 5, error message: sql: no rows in result set


8. Revision 2 not created yet so that also is not retrievable.
$ grpc_cli -loas2=false call localhost:6962 trillian.TrillianMap.GetSignedMapRootByRevision \
  'map_id:6052818873547722634 revision:2'
