HAL Removal

Summary

HAL is a behemoth, do-it-all, daemon to access hardware. It is now obsoleted by udisks (né DeviceKit-disks) and upower (né DeviceKit-power), as well as libudev for device discovery.

HAL package maintainer is planning to retire it for Fedora 16.

This feature tracks the removal of HAL in the Fedora Desktop spin.

Detailed Description

To generate the list of packages still depending on hal in rawhide:

$ repoquery --repofrompath=fedora-rawhide-i386,http://download.fedoraproject.org/pub/fedora/linux/development/rawhide/i386/os/ --repoid=fedora-rawhide-i386 --qf '%{NAME}' --whatrequires hal hal-info hal-libs hal-storage-addon | sort -u

Packages in the Desktop spin

Package name Status Bug reports or discussions
abrt-gui done Requires gnome-python2-gnomevfs (Fedora bug 652423)
cheese done upstream bug 594966
evolution done
evolution-data-server done
gdm done upstream bug 572765, Fedora bug 567432
gnome-power-manager done upstream bug 593933
gnome-vfs2 TODO GnomeVFS has been deprecated since 2008, applications should use gvfs instead. Packages depending directly on gnome-vfs2:

gnome-python2-gnome
gnome-python2-gnomevfs
libgnome (required by gnome-python2-bonobo, libbonoboui)
libgnomeui (required by gnome-python2-gnome)

gnome-python is also deprecated for GNOME3, applications should use PyGObject.
libbonoboui, libgnome and libgnomeui are also deprecated for GNOME3.
at-spi-python is also deprecated, applications should use pyatspi.
Since >100 other packages depend on gnome-vfs2, it may be useful to disable its HAL support, as was recently done by Debian (Debian bug 599020), but the goal is to get rid of GnomeVFS too.

Benefit to Fedora

Faster boot-up, and removal of obsoleted technology.

Scope

Loads of applications require HAL itself, or libhal. Applications should not rely on HAL, or libhal being available.

How To Test

Need to test:

  • yum remove hal-filesystem hal-libs
  • Check that nothing gets removed because it depends on hal
  • Check that applications that access hardware still work as before

User Experience

  • Faster boot-up
  • Possibly faster applications startup when switching from libhal to libgudev for device enumeration

Dependencies

  • See description

Contingency Plan

  • Still ship HAL.

Documentation

N/A

Release Notes

  • Fedora now does not ship with the HAL daemon, and libhal by default. If a specific application require libhal to function, please file a bug against it to be ported to the new technology.
