Created attachment 1640227 [details] script output with set -x while trying to do autocompletion. Description of problem: Bash autocompletion for dnf install lags by several seconds. Version-Release number of selected component (if applicable): 1:2.8-7.fc31 How reproducible: sudo dnf install gnome-<press tab to autocomplete> or sudo dnf install firefox<press tab to autocomplete> Steps to Reproduce: 1. Open a terminal and attempt to autocomplete sudo dnf install <program> Actual results: 4-6 second lag between presentation of the results Expected results: Results should be presented in 1-2 seconds at most. Additional info: The source of the lag appears to be between: 11116:32:16/usr/share//bash-completion/completions/dnf:_dnf_commands_helper:LINENO:/usr/bin/python3 -c 'import sys; from dnf.cli import completion_helper as ch; ch.main(sys.argv[1:])' install firefox -d 0 -q -C --assumeno --nogpgcheck^M 1116:32:20/usr/share//bash-completion/completions/dnf:_dnf_commands_helper:LINENO:echo 'firefox-pkcs11-loader-3.13.3-2.fc31.x86_64^M firefox-x11-70.0.1-4.fc31.x86_64^M firefox-x11-69.0.1-3.fc31.x86_64^M firefox-wayland-70.0.1-4.fc31.x86_64^M firefox-69.0.1-3.fc31.x86_64'^M Issue is only observed on Bash, Zsh completion works find. This issue makes it easier and/or faster to use dnf search to find packages vice autocompletion on bash.

This message is a reminder that Fedora 31 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora 31 on 2020-11-24. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 EOL if it remains open with a Fedora 'version' of '31'. 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. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 31 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 this bug is closed as described in the policy above. 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 31 changed to end-of-life (EOL) status on 2020-11-24. Fedora 31 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. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
