Michael Edge commented on CASSANDRA-10733:

OK - I've added tests and test data to cover both issues raised in this JIRA

We see a list of all tables (or functions, types) in the current keyspace plus a list of all
available keyspaces followed by a full stop (e.g. system.)

> {{'desc aggregate '}} displays the aggregates in the current keyspace (in this case,
only 1, called 'average') but does not display a list of available keyspaces. It only displays
the current keyspace, with no following full stop.

>          ;        <enter>  average  fxaggr

> Auto-complete on {{'desc table <keyspace>. '}} and {{'desc type <keyspace>.'}}
works correctly. We see a list of all tables (or types) in the current keyspace
> {code}
> cqlsh:fxaggr> desc table fxaggr.
> daydata              rawtickdatabylp      tickdata

> Auto-complete on {{'desc function <keyspace>. '}} and {{'desc aggregate <keyspace>.'}}
works inconsistently. In a keyspace with 2 functions, both beginning with the letters 'avg',
if I type {{'desc function <keyspace>'}} and hit tab, auto-complete will result in this:
{{'desc function fxaggr.avg '}} and will not display the matching functions. If I type {{'desc
function <keyspace>.'}} (note the trailing full stop) and hit tab, auto-complete will
work correctly:
> {code}
> cqlsh:fxaggr> desc function fxaggr.avg
> avgfinal  avgstate  
> {code}
> If I type {{'desc aggregate <keyspace>'}} and hit tab, auto-complete returns  {{'desc
aggregate <keyspace> '}}  (it adds a space) and does not show me the list of available
aggregates. If I type {{'desc aggregate <keyspace>.'}} (note the trailing full stop)
and hit tab, auto-complete will work correctly.
