s3:printing: Move pcap_cache_loaded() to load.c

2021-12-10T14:02:30+00:00

A future patch will remove the PRINTING dependency from smbd, but in
delete_and_reload_printers() we still reference it.

Maybe at some later stage we can remove reload_printers() overall, we
don't really need to load the full printer list into every smbd. All
we need is to load them on-demand for explicit listing functions, but
there we can throw them away again. And when someone connects to the
printer, we can also load them on demand.

printing: traverse_read the printer list for share updates

2014-08-08T12:10:38+00:00

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.
