https://fedoraproject.org/wiki/Changes/Plocate_as_the_default_locate_implementation == Summary == The venerable `mlocate` program is replaced by `plocate` — a compatible reimplementation that is faster and uses less disk space. == Owner == * Name: [[User:Zbyszek| Zbigniew Jędrzejewski-Szmek]] * Email: zbyszek at in.waw.pl * Name: [[User:Msekleta| Michal Sekletár]] * Email: msekleta at redhat.com == Detailed Description == Plocate is a newer implementation of `locate`/`mlocate` that using `liburing` and `libzstd` for speed. The database it creates on disk is also smaller. Debian recently switched to `plocate` as the default implementation (https://lwn.net/Articles/846405/). 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: # F35: `plocate` is made available for testing # F36: `mlocate` is replaced by `plocate` in comps # F37 or F38: `mlocate` will 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. == Scope == * Proposal owners: ** package `mlocate` (Review bug: https://bugzilla.redhat.com/show_bug.cgi?id=1931141, DONE) ** submit a pull request to comps with `s/mlocate/plocate/` * 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: none == Upgrade/compatibility impact == 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. == How To Test == # Install `plocate` (`sudo dnf install plocate --allowerasing`) # Wait for `plocate-updatedb.service` to finish (`sudo systemctl start plocate-updatedb.service`) # Use `plocate pattern` or `plocate -r <regexp>` to search for files. == User Experience == 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. == Dependencies == None. == Contingency Plan == * Contingency mechanism: (What to do? Who will do it?) N/A (not a System Wide Change) * Contingency deadline: N/A (not a System Wide Change) * Blocks release? N/A (not a System Wide Change) == Documentation == N/A (not a System Wide Change) == Release Notes == `plocate` is now used as the default provider of `/usr/bin/locate` instead of `mlocate`. -- Ben Cotton He / Him / His Fedora Program Manager Red Hat TZ=America/Indiana/Indianapolis _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
