In Ubuntu, we've applied the attached patch to achieve the following:
* Merge from debian unstable. Remaining changes:
- when upgrading, ensure the index is fully rebuild (in the
background) to ensure that we get updated information in
/var/lib/apt-xapian-index/{index.values} and that the index
fully utilizes the new plugins (LP: #646018)
- use ionice for the index building
We thought you might be interested in doing the same.
This is only needed on upgrade and until the weekly cron job kicks
in. But because 0.39 adds the new catalogued time plugin its useful
to rebuild so that the data is available. Its not strictly needed
though as the client can also just read the values file and skip
using cataloguedtime if its missing there.
Cheers,
Michael
