Description Chris Ward 2010-06-28 06:29:29 EDT
Description of problem:

%> time bkr distros-list
real	3m4.076s
user	0m1.996s
sys	0m0.116s

There is no output suggesting what's happening until the user is finally hit with a massive amount of streaming output once the data is retrieved. 

The time it takes to grab all available distros-list is a little on the long-side. 3 min. +  and i assume as we continue forward in time, this will get longer...

I think a saner default would be to first tell the user something, eg:

%> bkr distros-list
Searching... (filters set...)

Then use some default filter, say for example filter based on InstallName's which contain references to this month/year. 

INFO: Using Defaults (Filter: InstallName = `date '+%Y%m'`)

This way, A) users will know what's going on as it's happening B) will get a quick response C) will realize it's better to be explicit than implicit.

Another option might be to set (eg) --limit = 100 as default and force users to set --limit = 0 if they actually want to return /all/ available distros, unfiltered.

I'm making the default 10.
