commit 4f0077cd6a8ffcb9f4980d71c9fc434f7fc1051c
Author: David Disseldorp <ddiss at suse.de>

s3-printing: remove duplicate cups response processing code
There is currently a lot of duplicate code included for processing
responses to CUPS_GET_PRINTERS and CUPS_GET_CLASSES requests. This
change splits this code into a separate function.

s3-printing: use printcap IDL for IPC
Use printcap IDL for marshalling and unmarshalling messages between cups
child and parent smbd processes. This simplifies the IPC and ensures
the parent is notified of cups errors encountered by the child.

idl: define printcap IPC message format
Signed-off-by: Günther Deschner <gd at samba.org>
commit 683b0652e23b787c5038ff5d7466fdc2a8b3c07f
Author: David Disseldorp <ddiss at suse.de>
Date: Tue May 24 11:34:59 2011 +0200
s3-printing: an empty cups printer list is treated as an error
cups_async_callback() is called to receive new printcap data from a
child process which requests the information from cupsd.
Newly received printcap information is stored in a temporary printcap
cache (tmp_pcap_cache). Once the child process closes the printcap IPC
file descriptor, the system printcap cache is replaced with the newly
populated tmp_pcap_cache, however this only occurs if tmp_pcap_cache is
non null (has at least one printer).
If the printcap cache is empty, which is the case when cups is not
exporting any printers, the printcap cache is not replaced resulting in
stale data.
