Package: cupsys
Version: 1.2.1-2
I tried upgrading, and other than the massive config file changes,
(WHY does the CUPS documentation have to be SO BAD? Just for example,
the "Order" directive docs say it defined whether Allow or Deny rules are
searched first. Fine, but I don't care which is matched first, but which
takes precedence: if both an Allow and a Deny rule match, WHICH ONE WINS?
It appears that the LAST match wins, which is not explained ANYWHERE.
And why is there an Order directive in config file sections where there
ARE no Allow or Deny lines? And what's this @OWNER and @SYSTEM stuff?
And what is this "PTAL hpjd:<address>" thing I'm being prompted to add as
a new printer? That doesn't look like a valid DeviceURI to me. And why
does the new config file say "Allow <address>" while the old one said
"Allow from <address>". Is there any semantic difference, or is "from"
just syntactic noise? Etc., etc., etc.)
er... as I was saying, after dealing with the config file overhaul,
I was noticing that the daemon would disappear at frequent intervals.
Tracing it revealed that it was dying on SIGSEGV. Here's an
example while browing the web interface (just after the execve of
/usr/lib/cups/cgi-bin/printers.cgi completed) with "LogLevel debug" set:

22344 --- SIGSEGV (Segmentation fault) @ 0 (0) ---
I have no idea what the [CGI] messages are talking about, but perhaps
they will be of some use to a scholar of such arcana.
The local configuration is unremarkable, with a few Allow lines added
to cupsd.conf for the local /24 network, and one directly connected
printer and a few HP JetDirect (socket://hostname:9100/) connections.
x86_32 server with 2.6.16 kernel.
No printing was happening at the time of the crash. 1.1.23-15 ran fine.
I'm reverting to 1.1.23-15 for a while.
Anyway, thanks for struggling with this hideous monstrosity.
