Red Hat Bugzilla – Bug 1257635
[fix available] sometimes LO doesn't see cups printers
Last modified: 2016-11-03 15:01:37 EDT
Description of problem:
I install LO on a RHEL 7.2 install without printers configured. I run LO for a while and exit. I then:
* vim /etc/cups/cupsd.conf and add "BrowsePoll cups.bos.redhat.com:631"
* vim /etc/cups/client.conf and add "ServerName cups.bos.redhat.com:631"
service cups restart
After the restart, LO only still has "Generic Printer" in the list of printers. If I then reboot the system, then I see the full list of printers that I would expect to see after the restart command.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. See Above.
Printers do not show up after "service cups restart"
Printers DO show up after "service cups restart"
Fresh install of RHEL-7.2 + yum update to LibreOffice 184.108.40.206 (etc) + vpn into redhat network. Followed the exact steps to reproduce and I get a full list of printers.
But if I leave libreoffice alone for a while, and revisit then it says just "generic printer", but another attempt to launch the print dialog will show them again. Maybe there is a timeout issue or something of that nature at work.

We're calling httpConnectEncrypt and then httpClose on its get and then using cupsGetDests and sometimes we get 0 printers back. If I change this to the more logical httpConnectEncrypt and use its result with cupsGetDests2 and then clean up with httpClose I consistently get results so I reckon we can solve this that way.
Fixed by rebase to 5.0.x: bug 1290148.
