RADb does not give data sometimes.
This happens very rarely (once a month) , so I can’t find the exact cause.
Is it possible not to print a standard template, if bgp3 got 0 networks?
Can you please explain what do you mean by "standard template" ?
Second question: let's assume AS-CLIENT contains N autonomous systems,
RADB returns some prefixes for K of them and zero prefixes for the rest.
What shall be generated in this case: some kind of warning/"standard
template" or normal prefix-list ?
Now I get (if the problem happened)
bgpq3 -J -S radb,ripe -l Client AS-CLIENT
policy-options {
replace:
prefix-list Client {
}
}
And the client without networks :(
To avoid uploading empty prefix-lists to routers in automatical mode,
you may introduce step of checking "if generated prefix-list is empty
(generated file is five lines long) then do not upload it to routers"
in your prefix-list update system.

For the juniper these are these 5 lines, for Cisco 3 lines.
It seems to me that focusing on the number of lines is not ideal.
May be add additional exit codes?
For example:
2 - If the number of networks received in any object (parent or child) 0.
3 - If number of AS in as-set 0
and other...

If you generating filters for different vendors, your tool is already
aware about vendor specifics (else it will call bgpq3 with wrong
vendor option). Extending this knowledge to the step of checking
"generated prefix-list is empty" shall not be a problem..

On any level of recursion ? Say, you build filter for AS-CUSTOMER,
which includes AS111 (customer itself), AS222 (customer of your customer)
and AS-ANOTHER-CUSTOMER. Shall bgpq3 fail in case when AS222 or
some AS included in AS-ANOTHER-CUSTOMER becomes empty ?

Yes. I understand that there will be many false positives.
Of course, this should be enabled by the option. (It’s a pity that -p_aranoiac is busy)
It is not very scary to run in automatic mode with this option.
If it is difficult, I will count the lines.
