This message is a reminder that Fedora 16 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 16. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '16'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 16's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 16 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged to click on "Clone This Bug" and open it against that version of Fedora. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping Fedora 16 changed to end-of-life (EOL) status on 2013-02-12. Fedora 16 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed. |
Description of problem: Every time a printer changes state, the entire list of printers is fetched using cupsGetDests(). This can be a very expensive operation in the case of having very many printers configured, and would be better avoided. cupsGetDests() only really needs to be called once, to get a full list of printers. That list, and the printers' attributes, can be updated as needed using IPP notifications. Version-Release number of selected component (if applicable): gnome-settings-daemon-3.2.1-1.fc16.x86_64 ref. gsd-print-notifications-manager.c:429-564 } else if (g_strcmp0 (signal_name, "PrinterStateChanged") == 0) { [...] } Note that printer states many change very often, and there may be a great many printers configured. In this situation, printer states are more likely to change more often, exacerbating the problem.
