cups-filters 1.26.0 released!

[Till Kamppeter <till.kamppeter@gmail.com>]

Hi,

I have released cups-filters 1.26.0 now, with the following changes:

	- cups-browsed: When generating local queues for printers for
	  which the local CUPS daemon would provide temporary queues
	  use the PPDs generated by libcupsfilters and not the ones
	  generated by CUPS. The PPD generation of libcupsfilters also
	  works with IPP-1.x-only printers, printers which do not
	  support to query "media-col-database" and printers which
	  support driverless printing only via PCLm. This can be
	  changed via the "UseCUPSGeneratedPPDs" directive in
	  cups-browsed.conf (Issue #22).
	- libcupsfilters: Re-structured the get_printer_attributes()
	  function to remove the recursive calls for the fallbacks, to
	  check required attributes in the response only if requested,
	  and to fully integrate the method of getting a suitable
	  response for a full printer capability list also if the
	  printer is only IPP 1.1 or does not support the
	  "media-col-database" attribute (Issue #22, Issue #163).
	- libcupsfilters, cups-browsed, driverless: Moved the funtions
	  get_printer_attributes() and resolve_uri() from cups-browsed
	  into libcupsfilters, to share them with the driverless
	  utility (Issue #22).
	- implicitclass: Fixed wrong stdout redirection from the
	  filters to the IPP backend and hard-coded path for "ipp"
	  backend call (Possible fix for Issue #163, Issue #181).
	- cups-browsed, driverless: Use DNS-SD-service-name-based URIs
	  instead of host-name-based ones, as CUPS also does. In
	  cups-browsed one can switch back to the conventional
	  host-name-based URIs via the new "DNSSDBasedDeviceURIs"
	  configuration option.  Note that cups-browsed always uses
	  conventional URIs for printers discovered via legacy CUPS
	  browsing or LDAP.
	- cups-browsed: When removing a CUPS queue, do not consider an
	  error (and retry) if the queue does not actually exist. Also
	  ignore errors when checking whether there are still
	  jobs. This way when a new queue gets created and the
	  generation of the PPD file fails the attempt to remove this
	  non-existing queueu when removing the printer entry does not
	  cause any problem.
	- cups-browsed: Improved the fallback mechanism of the
	  get_printer_attributes() function. Instead of considering
	  the request failed by the content of the response only when
	  not more than the two language atrributes come out, we check
	  through a list of required attributes whether they are all
	  there.  In addition, we actually fail when all callbacks
	  have failed (Issue #22).
	- cups-browsed: Introduced new configuration options
	  "UpdateCUPSQueuesMaxPerCall" and
	  "PauseBetweenCUPSQueueUpdates" to limit the amount of local
	  CUPS queues created, modified, or removed in a single event
	  callback. Before, when there were thousands of printers in
	  the network, cups-browsed got blocked for other tasks, like
	  assigning a destination printer for a cluster print job
	  (Issue #163).

This release adds some new features to cups-browsed and to the driverless 
utility: Both now use DNS-SD-service-name-based URIs for IPP print queues, like 
CUPS does. These URis are independent of network interfaces and ports and so 
make providing IPP services on the local machine (Printer Applications) easier. 
cups-browsed creates large numbers of local queues in portions now, so that it 
can treat jobs to print clusters between the portions, this makes printing more 
reliable in large networks with many printers. In addition, a lot of bugs got fixed.

Please release this on Debian so that it can sync into Ubuntu.

Thanks in advance.
