* s3: printing: Fix problem with server taking too long to respond to a ↵Jeremy Allison2014-02-181-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MSG_PRINTER_DRVUPGRADE message. Receiving a MSG_PRINTER_DRVUPGRADE causes smbd to iterate over all printers looking for ones that uses the driver. This is a very expensive operation requiring a read of all registry printer parameters. On a system with a large number of printers, this causes the clients to timeout (smbd can take longer than 60 seconds to respond). This patch fixes the problem by forwarding the MSG_PRINTER_DRVUPGRADE to the background lpq queue updater process and allowing it to take care of the updating of the changeid in the registry, allowing the smbd connected to the client to return to processing requests immediately. https://bugzilla.samba.org/show_bug.cgi?id=9942 Signed-off-by: Jeremy Allison <jra@samba.org> Reviewed-by: Andreas Schneider <asn@samba.org> Autobuild-User(master): Andreas Schneider <asn@cryptomilk.org> Autobuild-Date(master): Tue Feb 18 17:48:30 CET 2014 on sn-devel-104

* s3fs-smbd: Move housekeeping to the background process.Andreas Schneider2012-10-011-0/+9
| | | | | | | | | | | | | | | | If you add 200 printers using lpadmin. Then you wait for the printcap cache to expire. As soon as this expires we notify all deamons that they should reload the printers. This mean we need to create the default registry keys for each printer. If you do e.g. a 'smbclient -L' during that time you will get a lot of timeouts. This lets the housekeeping function of the printcap cache do the task of creating the default registry keys in background queue process. When it is done with the task it will tell all smbd childs to reload the printers and the 200 printers appear.

* s3-printing: Do not try to force reload.Simo Sorce2011-08-101-1/+5
| | | | | | | | | | Be more correct in load printers at startup. If async process have already started we do not need to force a reload, but we just need to load the printers. If other process have not finished initializing it makes no sense to try to force them as they are masking SIGHUP unitl init is done anyway. Signed-off-by: Andreas Schneider <asn@samba.org>
