cupsd.conf

This is the cupsd.conf we use.	It is a little non-standard (sends browse
queries but does not accept any).
Comment 6 Orion Poplawski 2006-05-15 16:36:13 EDT
Watching cups during reload:

- main.c:631 -> cupsdStopServer -> cupsdStopBrowsing closes the browe socket and
sets BrowseSocket to -1.

- Here:
#0  0x00839ca3 in read_configuration (fp=0x9c614d8) at conf.c:2285
#1  0x0083c2f9 in cupsdReadConfiguration () at conf.c:456
#2  0x00843b6b in main (argc=1, argv=0xbfba49c4) at main.c:637

NumBrowsers gets set to 1

- Here:
#0  send_cups_browse (p=0x8e63fd0) at dirsvc.c:2608
#1  0x007d6d84 in cupsdDeletePrinter (p=0x8e63fd0, update=0) at printers.c:681
#2  0x007d6e7b in cupsdDeleteAllPrinters () at printers.c:571
#3  0x007b2c3a in cupsdReadConfiguration () at conf.c:938
#4  0x007b9b6b in main (argc=1, argv=0xbf9a6b64) at main.c:637

  NumBrowsers gets set to 0

- main.c:668 -> cupsdStartServer -> cupsdStartBrowsing sets BrowseSocket to 2,
reopened.


So, NumBrowsers gets left at 0 and no browsing.

- NumBrowsers gets set by read_configuration (conf.c:1998)
