* printing: return last change time with pcap_cache_loaded()David Disseldorp2014-08-081-1/+1

* printing: traverse_read the printer list for share updatesDavid Disseldorp2014-08-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | The printcap update procedure involves the background printer process obtaining the printcap information from the printing backend, writing this to printer_list.tdb, and then notifying all smbd processes of the new list. The processes then all attempt to simultaneously traverse printer_list.tdb, in order to update their local share lists. With a large number of printers, and a large number of per-client smbd processes, this traversal results in significant lock contention, mostly due to the fact that the traversal is unnecessarily done with an exclusive (write) lock on the printer_list.tdb database. This commit changes the share update code path to perform a read-only traversal.

* s3-printing: reload shares after pcap cache fillDavid Disseldorp2011-01-071-4/+2
| | | | | | | | | | | | | | | | Since commit eada8f8a, updates to the cups pcap cache are performed asynchronously - cups_cache_reload() forks a child process to request cups printer information and notify the parent smbd on completion. Currently printer shares are reloaded immediately following the call to cups_cache_reload(), this occurs prior to smbd receiving new cups pcap information from the child process. Such behaviour can result in stale print shares as outlined in bug 7836. This fix ensures print shares are only reloaded after new pcap data has been received.

printing/load.c so swat can get it without linking to the backend code ------------ The following series of commits are for the new tdb based printing backend. This completely replaces our old printing backend. Major changes include: - all print ops are now done in printing/*.c rather than scattered all over the place - system job ids are decoupled from SMB job ids - the lpq parsers don't need to be nearly so smart, they only need to parse the filename, the status and system job id - we can store lots more info about a job, including the full job name - the queue cache control is much better I also added a new utility routine file_lines_load() that loads a text file and parses it into lines. This is used in out lpq parsing and I also want to use it to replace all of our fgets() based code in other places. (This used to be commit a902caf8d78ae4cb11ea3776d10273cb37d5fcd0)
