Plocate is a newer implementation of
mlocate that using
libzstd for speed.
The database it creates on disk is also smaller.
Debian recently switched to
plocate as the default implementation
It doesn't seem useful to maintain multiple locate implementations. Thus the new package Conflicts with the old one, so they cannot be installed in parallel.
The plan is:
plocateis made available for testing
mlocateis replaced by
- F37 or F38:
mlocatewill be retired (or given away, if somebody wants to pick it up)
Benefit to Fedora
We save some cpu cycles and disk sectors by using a more modern implementation of a common tool.
- Proposal owners:
mlocate(Review bug: https://bugzilla.redhat.com/show_bug.cgi?id=1931141, DONE)
- submit a pull request to comps with
- Other developers: install plocate locally and test if it works as expected on F35 and other versions
- Release engineering: n/a
- Policies and guidelines: n/a
- Trademark approval: n/a
- Alignment with Objectives:
The upgrade should be mostly invisible. It is possible that somebody might be relying on some very specific
mlocate behaviour or parsing the
mlocate database directly, but no such cases are currently known.
Plocate indexes bind mounts by default, while mlocate did not (bug 906591). This is a bug fix / positive change in behaviour.
How To Test
sudo dnf install plocate --allowerasing)
- Wait for
plocate-updatedb.serviceto finish (
sudo systemctl start plocate-updatedb.service)
plocate -r <regexp>to search for files.
Users should not notice the difference. Installing
plocate automatically removes
mlocate. The new implementation is generally compatible with the old one in all common cases, and provides some additional options.

plocate is now used as the default provider of
