+++ This bug was initially created as a clone of Bug #811285 +++ I see the same behaviour in Fedora 18. Yum autocompletion is very slow. Still I consider this as a feature request, not bug. bash-completion-2.0-2.fc18.noarch yum-3.4.3-51.fc18.noarch In bash, when you hit tab after typing 'yum install gnome', bash invokes helper script to get possible completion. It takes few seconds to finish: $ time /usr/share/yum-cli/completion-helper.py -d 0 -C list available gnome >/dev/null real 0m4.368s user 0m2.876s sys 0m0.640s It would be good to speed it up to run at least 10 times faster to improve user experience.
Andrej, could you apply the proposed patch to /etc/bash_completion.d/yum.bash, then set YUM_CACHEDIR to your /var/cache/yum/ and test? On my box the completion-helper.py example above runs ~300ms, so speedup is not noticeable.
Created attachment 709974 [details] faster bash completion of available packages.
This message is a reminder that Fedora 18 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 18.

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 18's end of life. Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 18 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 change the 'version' to a later Fedora version prior to Fedora 18's end of life. 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.
Fedora 18 changed to end-of-life (EOL) status on 2014-01-14. Fedora 18 is no longer maintained, which means that it will not receive any further security or bug fix updates.
