[Bug 1529152] Re: slow completion for systemd units

[Brian Murray]

Hello Karl-Philipp, or anyone else affected,

Accepted systemd into bionic-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/systemd/237-3ubuntu10.41 in a few
hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
bionic to verification-done-bionic. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-bionic. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

** Changed in: systemd (Ubuntu Bionic)
       Status: In Progress => Fix Committed

** Tags added: verification-needed verification-needed-bionic

Bug description:
  [impact]

  systemctl tab completion is annoyingly slow.

  [test case]

  on a bionic system:

  $ systemctl status systemd-<tab>

  any unit can be used, or even <tab> before specifying any unit name
  chars.

  That will hang for sometimes a few seconds.

  [regression potential]

  this updates systemctl bash completion, so any regression would likely
  result in systemctl command misbehaving; most likely, failure to tab-
  complete.

  [scope]

  This is needed for Bionic and Xenial, however I am not currently
  planning to fix this for Xenial.

  This is fixed by upstream commit
  f28255e2d5695b0d060558ff8cbb2b526fc94cc0 and a few other previous
  commits, which are all included starting in v240, so this is fixed
  already in Eoan and later.

  [original description]

  Pressing <kbd>Tab</kbd> after entering `sudo systemctl status
  [existing service name without .service suffix]` into console it takes
  up to 5 seconds until the auto-completion completes. Until then the
  cursor can't be moved.
