CUPS 1.3 clients can't get queue state from CUPS 1.4 servers

[geofft]

This is a continuation of ticket #652, which we worked around locally by detecting pre-1.4 clients and falling back to an implementation of RFC-1179 lpq in five lines of Python.

We've opened  ticket #3619 in CUPS' bugtracker about this issue. They recommended trying a newer version of the 1.3.x branch, but that did not work for me. We should track down what's different between the lpq implementations in 1.3 and 1.4.

I'll note that although lpstat seemed to work for Jon, it does not for me (on Linerva, with cups-bsd 1.3.8-1+lenny8). Perhaps something is wrong with my syntax, but...

dr-wily:~ geofft$ lpstat -h get-print acantha
lpstat: No printer-uri in request!
dr-wily:~ geofft$ lpstat -h get-print -p acantha
printer acantha now printing acantha-0.  enabled since Sat 14 Aug 2010 04:01:44 PM EDT
        Connecting to printer...

(cvp has cups-bsd 1.4.3-1ubuntu1.2.) Should I expect something after "Connecting to printer..."?

Michael Sweet responds on  CUPS:3619:

“Geoffrey,

I know it has been a while, but if you can still reproduce this please
send me a debug error_log file from the server so I can see what is going
wrong.

Thanks!

and just so it is clear, I am unable to reproduce your problem going from
1.3.11 to 1.4.6 or current 1.5svn...”

I did a bisect on CUPS svn to figure out where the client first starts working against current servers:

IPP conformance: Get-Jobs has a default value for requested-attributes ( STR #3383)

So, this only affects Lenny and Hardy at this point, right? Do we plan to do the necessary work to get SRUs? Frankly, I'm fine with printing-config's hack (and printing-config can't go away as long as we have private queues behind an F5). We should either close this ticket or move to Upstream Utopia.

There is nothing we care about that still has CUPS 1.3
