New minor version
CHANGES IN V1.11.3 - cups-browsed: If a queue is not only discovered via Bonjour but also via legacy CUPS or LDAP, prefer the Bonjour record as it provides more information and there is also a defined cancellation broadcast. - cups-browsed: Let PPD options saved in the last session also get applied to generated PPDs for IPP network printers. - cups-browsed: Make sure that saved PPD options do not get lost if for some reason the PPD file cannot be loaded in a new cups-browsed session (or the loaded PPD file is different). This is done by holding a copy of the settings in the remote printer data structure. - cups-browsed: When saving option settings, remove backslashes added when the settings are read out via IPP request. Otherwise the backslashes would double with each session of cups-browsed. - implicitclass: Do not let the job get immediately retried on failure to send it out to the remote CUPS printer. By repeating to send the job to an unavailable server so quickly, cups-browsed gets bombed with requests and hangs on shutdown. - cups-browsed: Shortened timeouts of HTTP connections and IPP requests to 3 seconds amd of IPP requests to remote CUPS servers to 2 seconds. For local IPP requests always use the connection once created via http_connect_local(). Also call g_main_context_wakeup(NULL) after each g_main_loop_quit(gmainloop) call. These measures should reduce long hangs of cups-browsed on shutdown when a CUPS server got unavailable. - cups-browsed: Do not mark remote printers discovered via legacy CUPS broadcasts as disappeared right from the beginning to implement the browse timeout. Instead manage their expiring by introducing a flag which marks them as CUPS legacy printers. Printers with disappeared status are considered invalid in some situations, especially when clusterin equally-named remote printers (Bug #1374). - cups-browsed: When we have remote CUPS printers, we use the implicitclass backend and a local copy of the remote PPD file already if we have only a single remote printer with this queue name. This simplifies the management of remote CUPS printers and also we do not hassle with using a remote PPD file. Now one can change PPD option defaults with printer setup tools or the lpadmin command and they get preserved in the next cups-browsed sessions. - if we are using the implicitclass backend CUPS does not make the server's PPD file available on the client any more. To fix this, we download the PPD file when creating an implictclass:... queue and apply it to the queue. This way the options of the printer(s) are always available for enumeration, especially in print dialogs (Bug #1372). We modify the local copy setting any options saved from the previous session and inhibiting local execution of filters (as the driver for the remote printer is not necessarily available locally). - cups-browsed: Added flag to inhibit auto-backup of option settings by the on_printer_modified() notification handler during print queue setup and removal. - cups-browsed: Let the printer_record() function always return the master record for the printer name and not an arbitrary duplicate. - cups-browsed: Fixes in the functionality for saving option settings: Make sure to not save the same option twice with different values, do not save the "printer-is-shared" option (errors out when re-applying option in the next session). - cups-browsed: Treat discovered printers correctly also if they use a non-standard port, even if several CUPS daemons are running on the same server but on different ports. This also improves the support of a sandboxed printing stack. - cups-browsed: Close http connections opened for polling properties of IPP network printers, to fix a possible memory leak. - cups-browsed: Cleaned up HTTP access to local and remote CUPS servers and IPP printers, to assure that the local CUPS daemon is always accessed the same (user-defined) way (domain socket/localhost:port). This especially prevents cups-browwsed hanging on shutdown (Debian bug #832637). - cups-browsed: Fixed clustering equally-named queues of different remote servers, to assure to have one master referencing to all duplicates and not a daisy chain of duplicate references.
