RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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):
RHEL-7.2-20150817.n.2
libreoffice-4.3.7.2-5.el7.x86_64

How reproducible:
100%

Steps to Reproduce:
1. See Above.
2.
3.

Actual results:
Printers do not show up after "service cups restart"

Expected results:
Printers DO show up after "service cups restart"

Additional info:

Fresh install of RHEL-7.2 + yum update to LibreOffice 4.3.7.2 (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.

*** Bug 1257715 has been marked as a duplicate of this bug. ***

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.

Verified

RHEL-7.3-20160901.1
libreoffice-5.0.6.2-3.el7.x86_64
